Effectiveness of Two Web-Based Interventions for Chronic Cancer-Related Fatigue Compared to an Active Control Condition: Results of the "Fitter na kanker" Randomized Controlled Trial

A scoping review of therapist behaviors in guided digital mental health interventions

Guided digital mental health interventions are more effective than unguided interventions. While research often emphasizes the frequency and intensity of guidance, less attention has been paid to the behaviors enacted by the therapists supporting clients using these interventions. A scoping review of the literature was conducted to systematically examine the evidence on therapist behaviors (i.e., the actions and feedback provided by supporters to patients). Applying broad eligibility criteria, a systematic search was conducted in PubMed, PsycInfo, the Cochrane Library, and Embase from their inception to January 1st 2024. Sixteen studies met inclusion criteria and were included in the review. Following data extraction, a descriptive analysis and synthesis of the results was performed. Most studies (n = 12; 75 %) focused on therapist behaviors in the context of internet-delivered Cognitive Behavioral Therapy for anxiety and depression. While earlier studies primarily focused on identifying therapist behaviors, later studies shifted towards examining the associations between therapist behaviors and different outcomes, as well as deriving research and clinical applications for improving guided internet-delivered treatments. Identified gaps and recommendations for clinical practice, research, training, and treatment development are discussed.

Management of Fatigue in Adult Survivors of Cancer: ASCO-Society for Integrative Oncology Guideline Update

PURPOSE

To update the ASCO guideline on the management of cancer-related fatigue (CRF) in adult survivors of cancer.

METHODS

A multidisciplinary panel of medical oncology, geriatric oncology, internal medicine, psychology, psychiatry, exercise oncology, integrative medicine, behavioral oncology, nursing, and advocacy experts was convened. Guideline development involved a systematic literature review of randomized controlled trials (RCTs) published in 2013-2023.

RESULTS

The evidence base consisted of 113 RCTs. Exercise, cognitive behavioral therapy (CBT), and mindfulness-based programs led to improvements in CRF both during and after the completion of cancer treatment. Tai chi, qigong, and American ginseng showed benefits during treatment, whereas yoga, acupressure, and moxibustion helped to manage CRF after completion of treatment. Use of other dietary supplements did not improve CRF during or after cancer treatment. In patients at the end of life, CBT and corticosteroids showed benefits. Certainty and quality of evidence were low to moderate for CRF management interventions.

RECOMMENDATIONS

Clinicians should recommend exercise, CBT, mindfulness-based programs, and tai chi or qigong to reduce the severity of fatigue during cancer treatment. Psychoeducation and American ginseng may be recommended in adults undergoing cancer treatment. For survivors after completion of treatment, clinicians should recommend exercise, CBT, and mindfulness-based programs; in particular, CBT and mindfulness-based programs have shown efficacy for managing moderate to severe fatigue after treatment. Yoga, acupressure, and moxibustion may also be recommended. Patients at the end of life may be offered CBT and corticosteroids. Clinicians should not recommend L-carnitine, antidepressants, wakefulness agents, or routinely recommend psychostimulants to manage symptoms of CRF. There is insufficient evidence to make recommendations for or against other psychosocial, integrative, or pharmacological interventions for the management of fatigue.Additional information is available at www.asco.org/survivorship-guidelines.

What is needed for improved uptake and adoption of digital aftercare programs by cancer survivors: a mixed methods study applying the COM-B model

INTRODUCTION

Cancer survivors face physical, lifestyle, psychological, and psychosocial challenges. Despite the availability of aftercare services, survivors still have unmet needs. Digital aftercare programs may offer support, but their use is limited. This study aimed to examine what is needed to improve uptake and adoption of these programs. Additionally, it explored sociodemographic and clinical variables that may influence these needs.

METHODS

A mixed-methods approach was used, involving qualitative interviews and a questionnaire. The research was guided by the COM-B model of behaviour, which considers capability, opportunity, and motivation crucial for behaviour. Qualitative analysis was performed using the framework method. Statistical analyses involved descriptive statistics and regression analysis.

RESULTS

Fourteen cancer survivors were interviewed, and 213 participants completed the questionnaire. Findings indicated that most respondents had a positive or neutral attitude towards digital aftercare programs, believing these could address their cancer-related challenges. Still, only a small percentage had experience with them, and most were unaware of their existence. Many expressed a desire to be informed about them. Some were uncertain about their effectiveness. Others were concerned about a lack of reimbursement. No significant influence of the sociodemographic and clinical variables was found.

CONCLUSION

Cancer survivors are generally positive about digital aftercare programs but are often unaware of their availability. Raising awareness, clarifying their value, and providing support and reimbursement could enhance uptake and adoption.

IMPLICATIONS FOR CANCER SURVIVORS

The current insights can help improve participation in digital aftercare programs, ultimately fostering health, well-being, and quality of life of cancer survivors.

Looking at individual symptoms: the dynamic network structure of depressive symptoms in cancer survivors and their preferences for psychological care

PURPOSE

The majority of depressed cancer survivors do not receive psychological care, possibly because offered care does not align with their experiences and preferences. We examined (1) which depressive symptoms cancer survivors would like to receive psychological care for; (2) how distinct depressive symptoms are related to each other in the contemporaneous and temporal network of depressive symptoms; and (3) whether survivors' care needs correspond to the interconnectedness of these specific symptoms.

METHOD

Fifty-two cancer survivors suffering from at least mild depressive symptoms and were not receiving psychological care filled out a baseline questionnaire about their care needs for distinct depressive symptoms, followed by ecological momentary assessments (EMA) assessing depressive symptoms (14 days, five times a day). Multi-level vector autoregression analysis was used to estimate associations between distinct depressive symptoms as well as their centrality within the network.

RESULTS

Cancer survivors most strongly preferred to receive care for fatigue, feeling down, little enjoyment, and sleep problems. Fatigue, together with worry and lack of concentration, most strongly predicted the onset of other symptoms. Little enjoyment and feeling down were two of the most central symptoms (i.e., strongly connected to other symptoms) in the contemporaneous network and were most strongly influenced by other symptoms in the temporal network.

CONCLUSIONS

Clinicians can offer specific interventions that target fatigue, as these played an important role in the onset of symptoms and would align with survivors' needs.

IMPLICATIONS FOR CANCER SURVIVORS

Offering such symptom-specific care may increase the uptake of psychological interventions in cancer survivors.

Prevalence, severity, and risk factors of cancer-related fatigue among working cancer survivors: a systematic review and meta-analysis

PURPOSE

The aim of this study is to evaluate the prevalence, severity, and risk factors of cancer-related fatigue among currently working cancer survivors.

METHODS

We searched the PubMed, Embase, Scopus, CINAHL, Cochrane Library, and ICHUSHI databases. The risk of bias was evaluated independently using the Risk of Bias Assessment Tool for Non-randomized Studies (RoBANS). A meta-analysis was conducted to determine the prevalence, severity, and related factors associated with cancer-related fatigue among currently working cancer survivors.

RESULTS

Our meta-analysis included 18 studies and revealed that 42.2% of currently working cancer survivors experience cancer-related fatigue. The fatigue severity in this group was significantly higher than that in workers without cancer (absolute standardized mean difference (SMD) = 0.67), but lower than that in cancer survivors who had previously worked and were not currently working (absolute SMD = 0.72). Distress was identified as a potential risk factor for cancer-related fatigue in working cancer survivors (partial correlation coefficient = 0.38).

CONCLUSIONS

The high prevalence of cancer-related fatigue among employed cancer survivors underscores the need for targeted workplace interventions and fatigue management strategies. While the severity of fatigue is less than that seen in non-working survivors, the comparison with the general working population highlights a significant health disparity. The association between distress and fatigue suggests the necessity for a holistic approach to fatigue management that considers both physical and mental factors in working cancer survivors.

IMPLICATIONS FOR CANCER SURVIVORS

Our findings highlight the critical need for healthcare professionals and employers to monitor fatigue levels among working cancer survivors and offer appropriate support.

Guided versus non-guided digital psychological interventions for cancer patients: A systematic review and meta-analysis of engagement and efficacy

OBJECTIVE

To evaluate engagement with and efficacy of guided versus non-guided digital interventions targeting psychological symptoms of cancer via a systematic review of current evidence.

METHODS

PubMed, Scopus, PsychINFO, MEDLINE, and CINAHL databases were searched. Eligible publications were randomised controlled trials of guided or non-guided digital psychological interventions used in cancer settings reporting intervention efficacy and/or engagement. Study methodological quality was assessed using the Cochrane risk of bias (RoB) tool. Random effects meta-analyses were performed on outcomes with sufficient data, with sub-group analyses of intervention type and follow-up period.

RESULTS

Forty-three studies were included. Studies varied by level of guidance, type of technology used, duration, and outcomes assessed. Most studies had a high overall RoB. Meta-analysis indicated that guided interventions significantly reduced distress, anxiety, and fatigue, while non-guided did not. For depression and quality of life, both guided and non-guided interventions produced significant improvements. Guided interventions reported higher levels of intervention engagement than non-guided.

CONCLUSIONS

Guided digital psychological interventions were likely to be more effective than non-guided ones for cancer patients, particularly in reducing distress, anxiety, and fatigue. Whilst both types were found to improve depression and life quality, guided interventions were associated with higher patient engagement. These findings suggest digital interventions could supplement traditional cancer care, warranting further research concerning long-term effects and cost-efficiency.

A Web-Based Mindfulness-Based Cognitive Therapy for Couples Dealing With Chronic Cancer-Related Fatigue: Protocol for a Single-Arm Pilot Trial

BACKGROUND

Chronic fatigue is a common symptom among patients who have been treated for cancer. Current psychosocial interventions typically target the patient alone, despite growing evidence suggesting that a couples' approach can increase and broaden the efficacy of an intervention. Therefore, based on an existing web-based mindfulness-based cognitive therapy for patients, the couple intervention COMPANION was developed.

OBJECTIVE

The primary objectives of this study are to determine the acceptability of COMPANION and its potential efficacy in reducing fatigue in patients with cancer. Our secondary objectives are to examine the feasibility of the trial procedures and the potential working mechanisms of the couple intervention.

METHODS

We will conduct a single-arm pilot trial for couples (ie, patients with cancer with chronic fatigue and their partners). All couples are allocated to the web-based couple intervention that consists of psychoeducation, mindfulness, and cognitive-behavioral exercises. The 9 sessions of the intervention are supervised remotely by a trained therapist. Patients and partners will complete questionnaires before starting the intervention (T0), 2 weeks after completing the intervention (T1), and 1 month after T1 (T2). They will also fill out weekly diaries during the intervention period. A subsample of patients (n≈5) and partners (n≈5) as well as all the therapists providing COMPANION will participate in the final focus groups. Benchmark values have been defined to determine the acceptability (ie, ≥60% of couples complete the intervention and/or ≥70% of the participants are satisfied with the intervention) and potential efficacy (ie, a significant improvement in fatigue and/or a clinically relevant improvement in fatigue in 45% of the patients between T0 and T1) of the intervention. The trial procedures are deemed feasible if an average of at least three couples are included per recruiting month and/or adherence to the assessments is at least 65% for T1 and the diaries and 60% for T2. To establish potential working mechanisms, changes in affect, sleep, catastrophizing, partner communication and interactions, self-efficacy, mindfulness, and closeness will be examined. Quantitative outcomes will be interpreted along with the results from the focus groups.

RESULTS

Data collection is expected to be completed by March 2024.

CONCLUSIONS

This pilot trial will test the first web-based mindfulness-based cognitive therapy for couples targeting chronic cancer-related fatigue. Findings will indicate whether proceeding with a randomized controlled trial is warranted.

Effectiveness of online mindfulness-based interventions for cancer patients: a systematic review and meta-analysis

PURPOSE

Cancer is the second leading cause of mortality worldwide. Cancer negatively affects individuals' quality of life and overall health. Mindfulness-based interventions appear to be promising in the reduction of cancer- and treatment-related symptoms. This review aimed to determine the effectiveness of online mindfulness-based interventions on distress, anxiety, depression, stress, mindfulness, sleep disturbance, quality of life, rumination, fear of cancer recurrence, fatigue and post-traumatic growth among adult cancer patients.

METHODS

A literature search was conducted across five electronic databases. Only randomized controlled trials were eligible. Two reviewers independently screened the studies, extracted data, and performed quality assessment using the Cochrane risk of bias assessment tool. Meta-analyses were conducted using review manager software, and standardized mean difference was used to determine intervention effects. Heterogeneity was examined using the I2 statistics.

RESULTS

Ten studies were included with a total of 962 participants. Analyses revealed that online mindfulness-based interventions was effective in reducing distress (I2 = 98%；standardized mean difference = -2.21，95% confidence interval: -3.84 to 0.57；P = 0.008)， depression (I2 = 45%；standardized mean difference = -0.33，95% confidence interval: -0.64 to -0.03；P = 0.03), stress (I2 = 97%；standardized mean difference = -2.14，95% confidence interval: -4.24 to -0.03；P = 0.05) and sleep disturbance (I2 = 54%；standardized mean difference = -0.30，95% confidence interval: -0.59 to -0.01；P = 0.04), and improving quality of life (I2 = 94%；standardized mean difference = 0.92，95% confidence interval: 0.09-1.76；P = 0.03). The online mindfulness-based interventions had no significant effects on anxiety, mindfulness, rumination, fear of cancer recurrence, fatigue and post-traumatic growth. Subgroup analyses revealed that online mindfulness-based interventions resulted in higher effect sizes for distress when delivered by website than application, significantly higher effect sizes were also found for online mindfulness-based interventions with guidance, but not on treatment or cancer type. For sleep disturbance, and quality of life, no significant differences between subgroups were found.

CONCLUSION

These results provide preliminary support that online mindfulness-based interventions may be feasible and acceptable, which can be used as an adjuvant therapy for the management of cancer-related symptoms among cancer patients.

Evaluating the effectiveness of mindfulness alone compared to exercise and mindfulness on fatigue in women with gynaecology cancer (GEMS): Protocol for a randomised feasibility trial

BACKGROUND

In 2020 Globocan reported nearly 1.4 million new cases of gynaecology cancer worldwide. Cancer related fatigue has been identified as a symptom that can be present for gynaecology cancer patients many years after treatment. The current evidence around the management of this symptom suggests that exercise has the most positive outcome. However, some ambiguity remains around the evidence and whether it can address all areas of fatigue effectively. More recently, other interventions such as mindfulness have begun to show a favourable response to the management of symptoms for cancer patients. To date there has been little research that explores the feasibility of using both these interventions together in a gynaecology cancer population. This study aims to explore the feasibility of delivering an intervention that involves mindfulness and mindfulness and exercise and will explore the effect of this on fatigue, sleep, mood and quality of life.

METHODS/DESIGN

This randomised control trial will assess the interventions outcomes using a pre and post design and will also include a qualitative process evaluation. Participants will be randomised into one of 2 groups. One group will undertake mindfulness only and the other group will complete exercise and mindfulness. Both groups will use a mobile application to complete these interventions over 8 weeks. The mobile app will be tailored to reflect the group the participants have drawn during randomisation. Self-reported questionnaire data will be assessed at baseline prior to commencing intervention and at post intervention. Feasibility will be assessed through recruitment, adherence, retention and attrition. Acceptability and participant perspective of participation (process evaluation), will be explored using focus groups.

DISCUSSION

This trial will hope to evidence and demonstrate that combination of two interventions such as mindfulness and exercise will further improve outcomes of fatigue and wellbeing in gynaecology cancer. The results of this study will be used to assess (i) the feasibility to deliver this type of intervention to this population of cancer patients using a digital platform; (ii) assist this group of women diagnosed with cancer to manage fatigue and other symptoms of sleep, mood and impact their quality of life.

An eHealth App (CAPABLE) Providing Symptom Monitoring, Well-Being Interventions, and Educational Material for Patients With Melanoma Treated With Immune Checkpoint Inhibitors: Protocol for an Exploratory Intervention Trial

BACKGROUND

Since treatment with immune checkpoint inhibitors (ICIs) is becoming standard therapy for patients with high-risk and advanced melanoma, an increasing number of patients experience treatment-related adverse events such as fatigue. Until now, studies have demonstrated the benefits of using eHealth tools to provide either symptom monitoring or interventions to reduce treatment-related symptoms such as fatigue. However, an eHealth tool that facilitates the combination of both symptom monitoring and symptom management in patients with melanoma treated with ICIs is still needed.

OBJECTIVE

In this pilot study, we will explore the use of the CAPABLE (Cancer Patients Better Life Experience) app in providing symptom monitoring, education, and well-being interventions on health-related quality of life (HRQoL) outcomes such as fatigue and physical functioning, as well as patients' acceptance and usability of using CAPABLE.

METHODS

This prospective, exploratory pilot study will examine changes in fatigue over time in 36 patients with stage III or IV melanoma during treatment with ICI using CAPABLE (a smartphone app and multisensory smartwatch). This cohort will be compared to a prospectively collected cohort of patients with melanoma treated with standard ICI therapy. CAPABLE will be used for a minimum of 3 and a maximum of 6 months. The primary endpoint in this study is the change in fatigue between baseline and 3 and 6 months after the start of treatment. Secondary end points include HRQoL outcomes, usability, and feasibility parameters.

RESULTS

Study inclusion started in April 2023 and is currently ongoing.

CONCLUSIONS

This pilot study will explore the effect, usability, and feasibility of CAPABLE in patients with melanoma during treatment with ICI. Adding the CAPABLE system to active treatment is hypothesized to decrease fatigue in patients with high-risk and advanced melanoma during treatment with ICIs compared to a control group receiving standard care. The Medical Ethics Committee NedMec (Amsterdam, The Netherlands) granted ethical approval for this study (reference number 22-981/NL81970.000.22).

Navigating severe chronic cancer-related fatigue: an interpretative phenomenological analysis

OBJECTIVE

This article presents a phenomenological study on the embodied experiences of patients with Chronic Cancer-Related Fatigue (CCRF), aiming to better understand this complex phenomenon.

DESIGN

Data collection consisted of individual interviews with 25 participants who suffered from severe CCRF for at least three months after cancer treatment was finished.

MAIN OUTCOME MEASURES

Against the theoretical background of philosophical phenomenology, we explored embodied experiences, incorporated temporal and spatial aspects of living with CCRF. We applied interpretative phenomenological analysis (IPA) to analyze the transcripts of the interviews.

RESULTS

Using IPA, we identified four themes on how chronic fatigue is experienced post-cancer: (1) Worn out; (2) Diminishment of one's 'I can'; (3) Invisibility; and (4) Regaining one's 'I can'.

CONCLUSION

For clinical practice, these results imply that professionals could focus more on the role of the body and limitations of one's 'I can' when treating CCRF. By studying these embodied CCRF experiences in individual patients, future research could help personalize and optimize treatment.

Online mindfulness-based cognitive therapy for fatigue in patients with sarcoidosis (TIRED): a randomised controlled trial

BACKGROUND

Sarcoidosis-associated fatigue is highly prevalent and is often reported as the most burdensome symptom of sarcoidosis. Management of fatigue is challenging, and evidence-based therapies are lacking. In this TIRED trial, we aimed to assess the effects of a 12-week online mindfulness-based cognitive therapy (eMBCT) on fatigue.

METHODS

This study was a prospective, open-label, multicentre randomised controlled trial, conducted at three centres in the Netherlands. Eligible patients were 18 years or older, had stable sarcoidosis, and a score of more than 21 points on the Fatigue Assessment Scale (FAS). Patients were randomised into either the eMBCT or the control group. Participants completed patient-reported outcome measures at baseline, after intervention (T1), and 12 weeks after completion of eMBCT (T2). The primary outcome was the change in FAS score at T1 in the eMBCT group compared with the control group, assessed with the independent students't test in all patients who started the study. Secondary outcomes included within-group difference in FAS score at T1 and T2, between-group difference in FAS score at T2, and changes in the Hospital Anxiety and Depression Scale, the Freiburg Mindfulness Inventory-Short Form, and the Kings Sarcoidosis Questionnaire. The study was registered at the Netherlands Trial Register, NL7816.

FINDINGS

Between June 5, 2019, and Oct 28, 2021, 99 patients were randomly assigned to the eMBCT (n=52) or the control (n=47) groups. Six patients withdrew consent after psychological screening before the start of eMBCT. Baseline FAS score was similar in both groups (34·57 [SD 6·07] for 46 patients in the eMBCT group and 35·51 [4·65] for 47 patients in the control group). Mean change in FAS score at T1 was -4·53 (SD 5·77; p<0·0001) in the eMBCT group and -1·28 (3·80; p=0·026) in the control group (between-group difference 3·26 [95% CI 1·18 to 5·33; p=0·0025]). Furthermore, the eMBCT group had a significant improvement in anxiety (mean between-group difference 1·69, 95% CI 0·22-3·16; p=0·025), depressive symptoms (1·52, 0·08-2·95; p=0·039), mindfulness (3·1, 0·70-5·49; p=0·022), and general health status (6·28, 2·51-10·06; p=0·002) at T1, compared with the control group.

INTERPRETATION

12 week eMBCT improves fatigue, anxiety, depression, mindfulness, and health status in patients with sarcoidosis-associated fatigue.

Digital Health Interventions for Adult Patients With Cancer Evaluated in Randomized Controlled Trials: Scoping Review

BACKGROUND

Digital care has become an essential component of health care. Interventions for patients with cancer need to be effective and safe, and digital health interventions must adhere to the same requirements.

OBJECTIVE

The purpose of this study was to identify currently available digital health interventions developed and evaluated in randomized controlled trials (RCTs) targeting adult patients with cancer.

METHODS

A scoping review using the JBI methodology was conducted. The participants were adult patients with cancer, and the concept was digital health interventions. The context was open, and sources were limited to RCT effectiveness studies. The PubMed, CINAHL, Embase, Cochrane Library, Research Information Sharing Service, and KoreaMed databases were searched. Data were extracted and analyzed to achieve summarized results about the participants, types, functions, and outcomes of digital health interventions.

RESULTS

A total of 231 studies were reviewed. Digital health interventions were used mostly at home (187/231, 81%), and the web-based intervention was the most frequently used intervention modality (116/231, 50.2%). Interventions consisting of multiple functional components were most frequently identified (69/231, 29.9%), followed by those with the self-manage function (67/231, 29%). Web-based interventions targeting symptoms with the self-manage and multiple functions and web-based interventions to treat cognitive function and fear of cancer recurrence consistently achieved positive outcomes. More studies supported the positive effects of web-based interventions to inform decision-making and knowledge. The effectiveness of digital health interventions targeting anxiety, depression, distress, fatigue, health-related quality of life or quality of life, pain, physical activity, and sleep was subject to their type and function. A relatively small number of digital health interventions specifically targeted older adults (6/231, 2.6%) or patients with advanced or metastatic cancer (22/231, 9.5%).

CONCLUSIONS

This scoping review summarized digital health interventions developed and evaluated in RCTs involving adult patients with cancer. Systematic reviews of the identified digital interventions are strongly recommended to integrate digital health interventions into clinical practice. The identified gaps in digital health interventions for cancer care need to be reflected in future digital health research.

Impact of telehealth interventions on physiological and psychological outcomes in breast cancer survivors: A meta-analysis of randomised controlled trials

Introduction

The use of telehealth interventions has been evaluated in different perspectives in women and also supported with various clinical trials, but its overall efficacy is still ascertained. The objective of the present review is to identify, appraise and analyze randomized controlled trials on breast cancer survivors who have participated in technology-based intervention programs incorporating a wide range of physical and psychological outcome measures.

Material and methods

We conducted electronic search of the literature during last twenty years i.e., from 2001 till August 10, 2021 through four databases. Standardized mean difference with 95% confidence interval was used.

Results

A total of 56 records were included in the qualitative and 28 in quantitative analysis. Pooled results show that telehealth interventions were associated with improved quality of life (SMD 0.48, 95% CI 0.03 to 0.92, p=0.04), reduced depression (SMD -1.27, 95% CI =-2.43 to -0.10 p=0.03), low distress and less perceived stress (SMD -0.40, 95% CI =-0.68 to -0.12, p=0.005). However, no significant differences were observed on weight change (SMD -0.27, 95% CI =-2.39 to 1.86, p=0.81) and anxiety scores (SMD -0.09, 95% CI =-0.20 to 0.02, p=0.10) between the two groups. Improvement in health care competence and fitness among participants was also reported.

Conclusion

Study concludes that telehealth care is a quick, convenient and assuring approach to breast cancer care in women that can reduce treatment burden and subsequent disturbance to the lives of breast cancer survivors.

Patient preference attributes in eHealth interventions for cancer-related fatigue: A scoping review

INTRODUCTION

Cancer-related fatigue (CRF) is one of the most reported long-term effects breast cancer patients experience after diagnosis. Many interventions for CRF are effective, however, not for every individual. Therefore, intervention advice should be adjusted to patients' preferences and characteristics. Our aim was to develop an overview of eHealth interventions and their (preference sensitive) attributes.

METHODS

eHealth interventions were identified using a scoping review approach. Eligible studies included breast cancer patients and assessed CRF as outcome. Interventions were categorised as physical activity, mind-body, psychological, 'other' or 'combination'. Information was extracted on various (preference sensitive) attributes, like duration, intensity, peer support and costs.

RESULTS

Thirty-five interventions were included and divided over the intervention categories. (Preference sensitive) attributes varied both within and between these categories. Duration varied from 4 weeks to 6 months, intensity from daily to own pace. Peer support was present in seven interventions and costs were known for six.

CONCLUSION

eHealth interventions exist in various categories, additionally, there is much variation in (preference sensitive) attributes. This provides opportunities to implement our overview for personalised treatment recommendations for breast cancer patients struggling with CRF. Taking into account patients' preferences and characteristics suits the complexity of CRF and heterogeneity of patients.

A systematic review of the barriers and facilitators to adherence to mindfulness‐based cognitive therapy for those with chronic conditions

PURPOSE

Mindfulness-Based Cognitive Therapy (MBCT) can improve the lives of those with a chronic condition and psychological distress, however, high drop-out rates limit benefits. MBCT might be a candidate treatment for this population if nonadherence can be overcome. This review explores the existing literature on the barriers and facilitators to adherence to MBCT for those with chronic conditions.

METHOD

Databases MEDLINE, PsycINFO, CINAHL and Scopus were searched between 28^th May and 11th June 2021. We included empirical papers that identified barriers and/or facilitators to MBCT adherence in patients with chronic conditions-excluding non-English and grey literature. Papers were screened and duplicates removed. Extracted data included: setting, design, aim, sample-size, population and identified barriers/facilitators to MBCT adherence. The Mixed Methods Appraisal Tool (MMAT) was adapted and used to appraise the quality of studies RESULTS: Twenty papers were eligible for review. Synthesis identified six themes (in prevalence order): (1) Practical Factors (e.g., time and other commitments), (2) Motivation (e.g., change-readiness), (3) Patient clinical and demographic characteristics (e.g., current physical health), (4) Connection with Others (facilitators and group members), (5) Credibility (perception of the intervention) and (6) Content difficulty (intervention accessibility). Findings highlight potential adaptations to implementation (e.g., clear treatment rationale, preference matching, and eliciting and responding to individual concerns or obstructive assumptions) that could address barriers and harness facilitators.

CONCLUSION

This review contributes a higher order understanding of factors that may support/obstruct client adherence to MBCT with implications for future implementation in research and practice. Future research should prioritize open exploration of barriers/facilitators.

Impact of connected health interventions on psychological wellbeing and quality of life in patients with cancer: A systematic review and meta-analysis

OBJECTIVE

Connected health technologies have the potential to improve access to cancer care and support and reduce costs. We aimed to assess the impacts of interventions delivered using connected health technologies on psychological and quality of life (QoL) outcomes in people living with and beyond cancer.

METHODS

PUBMED, PsycINFO, Web of Science, and EMBASE were searched using terms relating to (i) cancer, (ii) connected health, and (iii) QoL/psychological wellbeing. Studies were included if they evaluated interventions using connected health technologies and assessed psychological and/or QoL outcomes for adults at any stage of cancer treatment or survivorship.

RESULTS

Thirty-seven studies met the inclusion criteria with a total of 8956 participants. Connected health technologies included web-based applications (n = 24), smart applications (n = 12), and wearable devices (n = 1). Studies were heterogeneous in terms of intervention components. We identified five clusters: (i) Psychosocial support and rehabilitation, (ii) psychoeducation and information support, (iii) symptom monitoring, reporting and self-management, (iv) peer and social support, and (v) health coaching and physical activity training. Due to heterogeneity of outcome measures, the meta-analysis included only seven RCTs; pooled mean estimates showed connected health interventions were moderately effective in reducing symptoms of depression (SMD: -0.226, 95% CI -0.303/-0.149) and anxiety (SMD: -0.188, 95% CI: 0.279/-0.0963) compared with usual care.

CONCLUSION

While the considerable heterogeneity observed highlights the need for more rigorous studies to improve reproducibility and efficiency, results suggest that connected health interventions have the potential to improve psychological wellbeing and QoL outcomes in people living with and beyond cancer.

Fatigue self-management led by occupational therapists and/or physiotherapists for chronic conditions: A systematic review and meta-analysis

OBJECTIVE

The aim of this study was to investigate the effectiveness of occupational therapist-/physiotherapist-guided fatigue self-management for individuals with chronic conditions.

METHODS

Eight databases, including MEDLINE and EMBASE, were searched until September 2019 to identify relevant studies. Randomised controlled trials and quasi-experimental studies of self-management interventions specifically developed or delivered by occupational therapists/physiotherapists to improve fatigue symptoms of individuals with chronic conditions were included. A narrative synthesis and meta-analysis were conducted to determine the effectiveness of fatigue self-management.

RESULTS

Thirty-eight studies were included, and fatigue self-management approaches led by occupational therapists/physiotherapists were divided into six categories based on the intervention focus: exercise, energy conservation, multimodal programmes, activity pacing, cognitive-behavioural therapy, and comprehensive fatigue management. While all exercise programmes reported significant improvement in fatigue, other categories showed both significant improvement and no improvement in fatigue. Meta-analysis yielded a standardised mean difference of the overall 13 studies: 0.42 (95% confidence interval:-0.62 to - 0.21); standardised mean difference of the seven exercise studies was -0.55 (95% confidence interval: -0.78 to -0.31).

DISCUSSION

Physical exercises inspired by the self-management principles may have positive impacts on fatigue symptoms, quality of life, and other functional abilities.

Systematic Review of Functional Outcomes in Cancer Rehabilitation

OBJECTIVE

To systematically review the evidence regarding rehabilitation interventions targeting optimal physical or cognitive function in adults with a history of cancer and describe the breadth of evidence as well as strengths and limitations across a range of functional domains.

DATA SOURCES

PubMed, Cumulative Index to Nursing and Allied Health Plus, Scopus, Web of Science, and Embase. The time scope was January 2008 to April 2019.

STUDY SELECTION

Prospective, controlled trials including single- and multiarm cohorts investigating rehabilitative interventions for cancer survivors at any point in the continuum of care were included, if studies included a primary functional outcome measure. Secondary data analyses and pilot/feasibility studies were excluded. Full-text review identified 362 studies for inclusion.

DATA EXTRACTION

Extraction was performed by coauthor teams and quality and bias assessed using the American Academy of Neurology (AAN) Classification of Evidence Scheme (class I-IV).

DATA SYNTHESIS

Studies for which the functional primary endpoint achieved significance were categorized into 9 functional areas foundational to cancer rehabilitation: (1) quality of life (109 studies), (2) activities of daily living (61 studies), (3) fatigue (59 studies), (4) functional mobility (55 studies), (5) exercise behavior (37 studies), (6) cognition (20 studies), (7) communication (10 studies), (8) sexual function (6 studies), and (9) return to work (5 studies). Most studies were categorized as class III in quality/bias. Averaging results found within each of the functional domains, 71% of studies reported statistically significant results after cancer rehabilitation intervention(s) for at least 1 functional outcome.

CONCLUSIONS

These findings provide evidence supporting the efficacy of rehabilitative interventions for individuals with a cancer history. The findings should be balanced with the understanding that many studies had moderate risk of bias and/or limitations in study quality by AAN criteria. These results may provide a foundation for future work to establish clinical practice guidelines for rehabilitative interventions across cancer disease types.

What web-based intervention for chronic cancer-related fatigue works best for whom? Explorative moderation analyses of a randomized controlled trial

PURPOSE

Approximately 25% of cancer patients suffer from chronic cancer-related fatigue (CCRF), which is a complex, multifactorial condition. While there are evidence-based interventions, it remains unclear what treatment works best for the individual patient. This study explored whether baseline characteristics moderated the effect of web-based mindfulness-based cognitive therapy (eMBCT) versus ambulant activity feedback (AAF) and a psycho-education control group (PE) on fatigue in patients suffering from CCRF.

METHODS

In a randomized controlled trial, participant suffering from CCRF participated in either eMBCT, AAF, or PE. Complete data of the treatment-adherent sample (≥ 6 sessions) was used to explore whether sociodemographic, clinical, and psychological characteristics at baseline moderated the intervention effect on fatigue severity at 6 months.

RESULTS

A trend showed that baseline fatigue severity and fatigue catastrophizing moderated the intervention effect. That is, at low levels of fatigue severity and catastrophizing, patients benefited more from AAF than from eMBCT and at high levels of fatigue severity and catastrophizing, patients benefited more from eMBCT than from PE.

CONCLUSIONS

This study found some preliminary evidence on what treatment works best for the individual suffering from CCRF. These findings emphasize the potential gain in effectiveness of personalizing treatment. An alternative approach that might help us further in answering the question "what treatment works best for whom?" is discussed.

eHealth Interventions for Dutch Cancer Care: Systematic Review Using the Triple Aim Lens

BACKGROUND

Globally, the burden of cancer on population health is growing. Recent trends such as increasing survival rates have resulted in a need to adapt cancer care to ensure a good care experience and manageable expenditures. eHealth is a promising way to increase the quality of cancer care and support patients and survivors.

OBJECTIVE

The aim of this systematic review was 2-fold. First, we aimed to provide an overview of eHealth interventions and their characteristics for Dutch patients with and survivors of cancer. Second, we aimed to provide an overview of the empirical evidence regarding the impact of eHealth interventions in cancer care on population health, quality of care, and per capita costs (the Triple Aim domains).

METHODS

The electronic databases Web of Science, PubMed, Cochrane, and Ovid PsycINFO were searched using 3 key search themes: eHealth interventions, cancer care, and the Netherlands. The identified interventions were classified according to predetermined criteria describing the intervention characteristics (eg, type, function, and target population). Their impact was subsequently examined using the Triple Aim framework.

RESULTS

A total of 38 interventions were identified. Most of these were web portals or web applications functioning to inform and self-manage, and target psychosocial factors or problems. Few interventions have been tailored to age, disease severity, or gender. The results of this study indicate that eHealth interventions could positively affect sleep quality, fatigue, and physical activity of patients with and survivors of cancer. Inconclusive results were found regarding daily functioning and quality of life, psychological complaints, and psychological adjustment to the disease.

CONCLUSIONS

eHealth can improve outcomes in the Triple Aim domains, particularly in the population health and quality of care domains. Cancer-related pain and common symptoms of active treatment were not targeted in the included interventions and should receive more attention. Further research is needed to fully understand the impact of eHealth interventions in cancer care on participation, accessibility, and costs. The latter can be examined in economic evaluations by comparing eHealth interventions with care as usual.

The design and evaluation of a health education control for comparison with cognitive behavioural therapy for individuals with acquired brain injury

Background

In psychological research, control conditions in the form of “treatment as usual” provide support for intervention efficacy, but do not allow the attribution of positive outcomes to the unique components of the treatment itself. Attentionally and structurally equivalent active control conditions, such as health education (HE), have been implemented in recent trials of cognitive behavioural therapy (CBT). However, descriptions and evaluations of these control conditions are limited. The aims of this paper were to (i) provide a detailed description and rationale for a novel HE active control condition and (ii) to evaluate the face validity, treatment integrity and feasibility of HE.

Method

We developed a HE active control similar in structure and duration to a CBT intervention for reducing sleep disturbance and fatigue (CBT-SF) in a pilot randomised controlled trial (n = 51). Face validity was measured using post-treatment participant satisfaction and helpfulness ratings for fatigue and sleep symptoms, treatment fidelity was measured with integrity monitoring ratings from an independent expert and feasibility was measured with completion and attrition rates. HE and CBT-SF groups were compared using Wilcoxon rank-sum tests and chi-square tests of independence.

Results

There were no significant differences in participant ratings of overall satisfaction between HE (n = 17) and CBT (n = 34) or in how helpful each intervention was for fatigue symptoms. Participants rated helpfulness for sleep symptoms higher in the CBT-SF group compared to HE. Integrity monitoring ratings were not significantly different for overall treatment delivery and therapist competency, but HE had greater module adherence than CBT-SF. There were no significant differences in completion or attrition rates between groups.

Conclusion

Our findings suggest that the HE control had adequate face validity, was delivered with fidelity and was feasible and suitable for use as a comparator for CBT-SF. In providing a real-world example of practical and theoretical issues we considered when designing this control condition, we aim to provide a framework and guidance for future investigators.

Effectiveness of online mindfulness-based interventions for improving mental health in patients with physical health conditions: Systematic review and meta-analysis

We aimed to determine the effectiveness of online mindfulness-based interventions (MBIs) for improving mental health in patients with physical health conditions. Randomized controlled trials (RCTs) in PubMed, Cochrane Library, Web of Science, Elsevier, and CINAHL published through September 2019 were searched. Two reviewers selected trials, conducted a critical appraisal, and extracted the data. Meta-analyses were performed. A total of nine RCTs were included. Analyses revealed that online MBIs was effective in improving depression [standardized mean difference (SMD) = -0.22, 95% confidence interval (CI) (-0.37, -0.07), p = 0.004], anxiety [SMD = -0.19, 95% CI (-0.33, -0.04), p = 0.01], and stress [SMD = -0.32, 95% CI (-0.52, -0.13), p = 0.001], and mindfulness [SMD = 1.67, 95% CI (0.14, 3.20), p = 0.03] in patients with physical conditions. We did not find any obvious effects on well-being [SMD = 1.12, 95% CI (-0.11, 2.36), p = 0.08]. Nevertheless, additional well-designed randomized clinical trials are further needed.

The modulatory role of internet-supported mindfulness-based cognitive therapy on extracellular vesicles and psychological distress in people who have had cancer: a protocol for a two-armed randomized controlled study

Background

Mindfulness-based interventions (MBIs) have been used in oncology contexts as a promising tool with numerous benefits for various health-related and psychosocial outcomes. Despite the increasing popularity of MBIs, few randomized controlled trials (RCTs) have examined their effects upon biological parameters. Specifically, no previous study has examined the effects of MBIs on extracellular vesicles (EVs), which are potentially important markers of health, disease, and stress. Moreover, the lack of RCTs is even more limited within the context of technology-mediated MBIs and long-term effects.

Methods

The current study protocol presents a two-arm, parallel, randomized controlled study investigating the effects of internet-supported mindfulness-based cognitive therapy (MBCT) compared with treatment as usual (TAU). Primary outcomes are psychological distress and EV cargo of distressed participants with previous breast, colorectal, or prostate cancer diagnoses. Secondary outcomes are self-reported psychosocial and health-related measures, and additional biological markers. Outcomes will be assessed at baseline, 4 weeks after baseline (mid-point of the intervention), 8 weeks after baseline (immediately post-intervention), 24 weeks after baseline (after booster sessions), and 52 weeks after baseline. Our goal is to recruit at least 111 participants who have been diagnosed with breast, prostate, or colorectal cancer (cancer stage I to III), are between 18 and 65 years old, and have had primary cancer treatments completed between 3 months and 5 years ago. Half of the participants will be randomized to the TAU group, and the other half will participate in an 8-week online MBCT intervention with weekly group sessions via videoconference. The intervention also includes asynchronous homework, an online retreat after the fifth week, and 4 monthly booster sessions after completion of the 8-week programme.

Discussion

This study will allow characterizing the effects of internet-based MBCT on psychosocial and biological indicators in the context of cancer. The effects on circulating EVs will also be investigated, as a possible neurobiological pathway underlying mind-body intervention effects.

Cancer health self-efficacy improvement in a randomized controlled trial

BACKGROUND

eHealth interventions can help cancer survivors self-manage their health outside the clinic. Little is known about how best to engage and assist survivors across the age and cancer treatment spectra.

METHODS

The American Cancer Society conducted a randomized controlled trial that assessed efficacy of, and engagement with, Springboard Beyond Cancer, an eHealth self-management program for cancer survivors. Intent-to treat analyses assessed effects of intervention engagement for treatment (on-treatment vs completed) overall (n = 176; 88 control, 88 intervention arm) and separately by age (<60 years vs older). Multiple imputation was used to account for participants who were lost to follow-up (n = 41) or missing self-efficacy data (n = 1) at 3 months follow-up.

RESULTS

Self-efficacy for managing cancer, the primary outcome of this trial, increased significantly within the intervention arm and for those who had completed treatment (Cohen's d = 0.26, 0.31, respectively). Additionally, participants with moderate-to-high engagement in the text and/or web intervention (n = 30) had a significantly greater self-efficacy for managing cancer-related issues compared to the control group (n = 68), with a medium effect size (Cohen's d = 0.44). Self-efficacy did not differ between the intervention and control arm at 3 months post-baseline.

CONCLUSIONS

Study results suggest that cancer survivors benefit variably from eHealth tools. To maximize effects of such tools, it is imperative to tailor information to a priori identified survivor subgroups and increase engagement efforts.

A randomized clinical trial of guided self-help intervention based on mindfulness for patients with hepatocellular carcinoma: effects and mechanisms

BACKGROUND

Compared with face-to-face mindfulness-based interventions (MBIs), online mindfulness interventions may be more convenient for patients with limited resources and can provide self-help mindfulness methods to improve the quality of life of cancer patients. This study investigated the effects of guided self-help mindfulness-based interventions (GSH-MBIs) on psychological distress, quality of life and sleep quality in patients with hepatocellular carcinoma and explored the underlying mechanisms.

METHODS

A total of 122 patients with hepatocellular carcinoma were randomly divided into the intervention group or the conventional treatment group. Psychological distress, quality of life, sleep quality, psychological flexibility and perceived stress were evaluated in the groups before the intervention at baseline, after the intervention, at 1-month follow-up and 3-month follow-up. The intervention's effects over time and the potential mediating effects were analysed using generalized estimating equations (GEE).

RESULTS

GEE results indicated significant time-group interaction effects on psychological distress (P < 0.001) and sleep quality (P < 0.001). The intervention significantly improved psychological flexibility (β, -2.066; 95% CI, -3.631, -0.500) and reduced perceived stress (β, -2.639; 95% CI, -4.110, -1.169). Psychological flexibility and perceived stress played a mediating role in the observed results.

CONCLUSION

GSH-MBIs can improve psychological distress and sleep quality via changing the psychological flexibility and perceived stress in hepatocellular carcinoma patients.

Efficacy and cost-effectiveness of an online mindfulness program (MindOnLine) to reduce fear of recurrence among people with cancer: study protocol for a randomised controlled trial

INTRODUCTION

Fear of cancer recurrence (FCR) is a common condition among cancer survivors that can lead to significant levels of distress, anxiety and depression. Online mindfulness programmes may provide the mechanism to support cancer survivors manage FCR and distress, and improve people's well-being over the short, medium and long term. The primary aim of this study is to determine the potential efficacy of MindOnLine, a 9 session mindfulness-based programme for survivors of breast, prostate and colorectal cancer. A formal economic programme will also be conducted.

METHODS AND ANALYSIS

A single-blind randomised controlled trial to determine the efficacy and cost-efficacy of a MindOnLine programme for cancer survivors. A total of 400 people living with cancer will be recruited via online advertisements on social media platforms, peak consumer advocacy groups or through outpatient services at healthcare providers across Victoria, Australia. People will be randomly allocated to either the MindOnLine programme (n=200) or waitlist control (n=200). Participant assessments will occur at baseline, at 9 weeks and 9-month follow-up. The primary outcome is change in Fear of Recurrence Index Score total score between baseline and 9 weeks; secondary outcomes are changes in depression and anxiety, quality of life and mindfulness. The economic analysis comprises a cost-consequences analysis where all outcomes will be compared with costs.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Peter MacCallum Cancer Centre (20-53) and Deakin University (2020-284). All participants will be required to provide written informed consent. Findings will be disseminated in peer reviewed journals and among key stakeholder organisations including hospitals, cancer and community organisations and Government. If successful the project will be rolled out nationally with a formal implementation plan.

Supportive Care Interventions for People With Cancer Assisted by Digital Technology: Systematic Review

BACKGROUND

Although relatively new, digital health interventions are demonstrating rapid growth because of their ability to facilitate access and overcome issues of location, time, health status, and most recently, the impact of a major pandemic. With the increased uptake of digital technologies, digital health has the potential to improve the provision of supportive cancer care.

OBJECTIVE

This systematic review aims to evaluate digital health interventions for supportive cancer care.

METHODS

Published literature between 2000 and 2020 was systematically searched in MEDLINE, PubMed, Embase, PsycINFO, Cochrane Central Register of Controlled Trials, and Scopus. Eligible publications were randomized controlled trials of clinician-led digital health interventions to support adult cancer patients. The interventions included were determined by applying a digital health conceptual model. Studies were appraised for quality using the revised Cochrane risk of bias tool.

RESULTS

Twenty randomized controlled trials met the inclusion criteria for the analysis. Interventions varied by duration, frequency, degree of technology use, and applied outcome measures. Interventions targeting a single tumor stream, predominantly breast cancer, and studies involving the implementation of remote symptom monitoring have dominated the results. In most studies, digital intervention resulted in significant positive outcomes in patient-reported symptoms, levels of fatigue and pain, health-related quality of life, functional capacity, and depression levels compared with the control.

CONCLUSIONS

Digital health interventions are helpful and effective for supportive care of patients with cancer. There is a need for high-quality research. Future endeavors could focus on the use of valid, standardized outcome measures, maintenance of methodological rigor, and strategies to improve patient and health professional engagement in the design and delivery of supportive digital health interventions.

Effects of a WeChat-based multimodal psychoeducational intervention on psychological well-being and quality of life in acute leukaemia patients in China: a randomised controlled trial

PURPOSE

The treatment and side effects of chemotherapy for acute leukaemia (AL) may cause both physical and psychological symptoms in patients. This study evaluated the effects of a WeChat-based multimodal psychoeducational intervention (ICARE programme) on fatigue, distress, anxiety, depression, and quality of life (QoL) among adult AL patients.

METHODS

In total, 72 participants were randomly assigned either to an intervention or control group (n = 36), respectively, from two large tertiary hospitals in Fuzhou, China (from April to December 2019). Data were collected at baseline, post-intervention, and after a 4-week follow-up using the Brief Fatigue Inventory, Distress Thermometer, Hospital Anxiety and Depression Scale, and Functional Assessment of Cancer Therapy-leukaemia. Descriptive statistics was used to summarise the sociodemographic and clinical characteristics of the participants and a linear mixed model was used to analyse the score changes.

RESULTS

Between the two groups, there were statistically significant improvements in fatigue, distress, anxiety, depression, physical well-being, social/family well-being, emotional well-being, functional well-being (all p < 0.001), and leukaemia-specific subscale (p = 0.001). The difference over time was significant for leukaemia-specific subscale and fatigue, both (p < 0.001), anxiety (p = 0.001), and social/family well-being (p = 0.005). The interaction effects were significant for fatigue, distress, anxiety, physical well-being, social/family well-being, and emotional well-being, all (p < 0.001), depression (p = 0.019), leukaemia-specific subscale (p = 0.008), and total QoL score (p = 0.004).

CONCLUSION

WeChat-based multimodal psychoeducational intervention demonstrated a significant effect in reducing fatigue, distress, anxiety, depression, and QoL in AL patients. This ICARE programme contributed to continuing care to support AL patients.

IMPLICATIONS FOR CANCER SURVIVORS

The ICARE programme can improve the mental health and QoL of AL patients. The application of WeChat-based psychoeducational interventions have significant potential to benefit cancer patients due to their reach and can be an added value to routine care.

Barriers and facilitators to the availability of efficacious self-directed digital health tools for adults living with cancer and their caregivers: A systematic literature review and author survey study

OBJECTIVE

This study aimed to examine barriers and facilitators to the dissemination of efficacious self-directed digital health tools for adults affected by cancer, and quantify funding used to develop and evaluate these digital health tools.

METHODS

We conducted: (1) a systematic literature review to identify efficacious self-directed digital health tools for adults affected by cancer, published between 2009 and 2019 and (2) an author survey to identify barriers and facilitators to dissemination of those tools, grant funding and the user centredness of their design (UCD) process.

RESULTS

Of 1314 screened articles, 29 articles describing 26 tools met the inclusion criteria. From 26 surveys sent, 12 were completed, 6 of which described disseminated tools. Whilst researchers' motivation and infrastructure support facilitate tool dissemination, limited funds, lack of infrastructure and limited research timelines are the most common barriers. A median of AUD$250,000 was spent on tools not disseminated to end-users.

CONCLUSION

Although incorporating UCD processes in the development of digital health tools is important, it is imperative to integrate implementation processes into the planning stages of tool development to ensure dissemination.

PRACTICE IMPLICATIONS

Researchers, academic institutions, funding agencies and government and non-government organisations all have roles to play to support long-term implementation.

Personalizing Psychological Care for Chronic Cancer-Related Fatigue: A Case Study on Symptom Dynamics

Approximately 25% of cancer patients suffer from chronic cancer-related fatigue (CCRF), which is a complex, multifactorial condition. While there are evidence-based interventions, it remains unclear what treatment works best for the individual patient. Psychological network models can offer a schematic representation of interrelations among fatigue and protective and perpetuating factors for the individual patient. We explored whether feedback based on these individual fatigue networks can help personalize psychological care for CCRF. A 34-year old woman with CCRF was referred to our mental healthcare institute for psycho-oncology. During the waitlist period, she filled out an experience sampling app for 101 days, including five daily assessments of fatigue, pain, mood, activity and fatigue coping. The interplay between items was visualized in network graphs at the moment-level and day-level, which were discussed with the patient. For example, acceptance of fatigue in the past three hours was associated with less hopelessness and less fatigue in the following moment. At the day-level, acceptance was also being associated with less fatigue, less hopelessness, a better mood, and more motivation to do things. The patient recognized these patterns and explained how unexpected waves of fatigue can make her feel hopeless. This started a dialogue on how cultivating acceptance could potentially help her handle the fatigue. The patient would discuss this with her therapist. Feedback based on individual fatigue networks can provide direct insight into how one copes with CCRF and subsequently offer directions for treatment. Further research is needed in order to implement this in clinical practice.

New Evidence in the Booming Field of Online Mindfulness: An Updated Meta-analysis of Randomized Controlled Trials

BACKGROUND

There is a need to regularly update the evidence base on the effectiveness of online mindfulness-based interventions (MBIs), especially considering how fast this field is growing and developing.

OBJECTIVE

This study presents an updated meta-analysis of randomized controlled trials assessing the effects of online MBIs on mental health and the potential moderators of these effects.

METHODS

We conducted a systematic literature search in PsycINFO, PubMed, and Web of Science up to December 4, 2020, and included 97 trials, totaling 125 comparisons. Pre-to-post and pre-to-follow-up between-group effect sizes (Hedges g) were calculated for depression, anxiety, stress, well-being, and mindfulness using a random effects model.

RESULTS

The findings revealed statistically significant moderate pre-to-post effects on depression (g=0.34, 95% CI 0.18-0.50; P<.001), stress (g=0.44, 95% CI 0.32-0.55; P<.001), and mindfulness (g=0.40, 95% CI 0.30-0.50; P<.001) and small effects on anxiety (g=0.26, 95% CI 0.18-0.33; P<.001). For well-being, a significant small effect was found only when omitting outliers (g=0.22, 95% CI 0.15-0.29; P<.001) or low-quality studies (g=0.26, 95% CI 0.12-0.41; P<.001). Significant but small follow-up effects were found for depression (g=0.25, 95% CI 0.12-0.38) and anxiety (g=0.23, 95% CI 0.13-0.32). Subgroup analyses revealed that online MBIs resulted in higher effect sizes for stress when offered with guidance. In terms of stress and mindfulness, studies that used inactive control conditions yielded larger effects. For anxiety, populations with psychological symptoms had higher effect sizes. Adherence rates for the interventions ranged from 35% to 92%, but most studies lacked clear definitions or cut-offs.

CONCLUSIONS

Our findings not only demonstrate that online MBIs are booming but also corroborate previous findings that online MBIs are beneficial for improving mental health outcomes in a broad range of populations. To advance the field of online MBIs, future trials should pay specific attention to methodological quality, adherence, and long-term follow-up measurements.

Trajectories of fatigue in cancer patients during psychological care

OBJECTIVE

Psycho-oncological institutions offer specialized care for cancer patients. Little is known how this care might impact fatigue. This study aimed to identify fatigue trajectories during psychological care, examined factors distinguishing these trajectories and predicted fatigue severity after nine months of psychological care.

DESIGN

Naturalistic, longitudinal study of 238 cancer patients receiving psycho-oncological care in the Netherlands. Data were collected before initiation of psychological care (T1) and three (T2) and nine months (T3) afterwards. Latent class growth analysis, repeated measure analyses (RMA) and linear regression analysis were performed.

MAIN OUTCOME MEASURES

Fatigue severity: Checklist Individual Strength.

RESULTS

Three fatigue trajectories were identified: high- (30%), moderate- (62%) and low-level fatigue (8%). While statistically significant decreases in fatigue were found, this decrease was not clinically relevant. RMA showed main effects for time for fatigue trajectories on depression, anxiety, personal control and illness cognitions. Fatigue severity and physical symptoms at T1, but not demographic or clinical factors, were predictive of fatigue severity at T3.

CONCLUSIONS

Fatigue is very common during psycho-oncological care, and notably not clinically improving. As symptoms of fatigue, depression, anxiety and physical symptoms often cluster, supplementary fatigue treatment should be considered when it is decided to treat other symptoms first.

Forming new habits in the face of chronic cancer-related fatigue: An interpretative phenomenological study

Purpose

The growing group of patients who suffer from chronic cancer-related fatigue (CCRF) after cancer have helpful and less helpful ways of responding to this long-lasting and disruptive problem. This qualitative study aimed to gain insight in essential elements of how patients respond to CCRF, with a focus on helpful responses to facilitate adaptation.

Methods

We conducted semi-structured interviews with a purposive sample of 25 participants who experienced severe CCRF for at least 3 months. Participants were recruited via media, patient associations, meetings, and health professionals until data saturation was attained. We used a topic guide with open-ended questions about lived experiences. Interpretative phenomenological analysis (IPA) was used for analysis of the transcripts.

Results

We identified five interrelated themes of how patients respond to CCRF: (1) discovering physical and emotional boundaries; (2) communicating support needs; (3) reorganizing and planning activities and rest; (4) letting go of one’s habitual identity; and (5) recognizing and accepting CCRF.

Conclusion

This study highlights the development of new habits and positive beliefs in the face of CCRF and the importance of (social) support in this process. This experiential knowledge on helpful responses can be used to inform patients and their significant others and improve self-efficacy. Health professionals could use these insights to improve recognition of CCRF and personalize treatment.

Effects of mindfulness-based interventions on fatigue in cancer survivors: A systematic review and meta-analysis of randomized controlled trials

This systematic review and meta-analysis was designed to determine the efficacy of mindfulness-based interventions (MBIs) in improving fatigue-related outcomes in adult cancer survivors. Randomized controlled trials (RCTs) were identified from PubMed, MEDLINE, PsycINFO, CINAHL, Web of Science, and EMBASE databases and reference lists of included studies. Separate random-effects meta-analyses were conducted for fatigue and vitality/vigor. Twenty-three studies reporting on 21 RCTs (N = 2239) met inclusion criteria. MBIs significantly reduced fatigue compared to controls at post-intervention (g = 0.60, 95 % CI [0.36, 0.83]) and first follow-up (g = 0.42, 95 % CI [0.20, 0.64]). Likewise, MBIs significantly improved vitality/vigor at post-intervention (g = 0.39, 95 % CI [0.25, 0.52]) and first follow-up (g = 0.35, 95 % CI [0.03, 0.67]). The evidence grade was low due to risk of bias, substantial heterogeneity, and publication bias among studies. MBIs show promise in improving fatigue and vitality/vigor in cancer survivors. More rigorous trials are needed to address current gaps in the evidence base.

Use of mHealth to Increase Physical Activity Among Breast Cancer Survivors With Fatigue: Qualitative Exploration

BACKGROUND

Physical activity has shown beneficial effects in the treatment of breast cancer fatigue; nevertheless, a significant portion of patients remain insufficiently physically active after breast cancer. Currently most patients have a smartphone, and therefore mobile health (mHealth) holds the promise of promoting health behavior uptake for many of them.

OBJECTIVE

In this study, we explored representations, levers, and barriers to physical activity and mHealth interventions among inactive breast cancer patients with fatigue.

METHODS

This was an exploratory, qualitative study including breast cancer patients from a French cancer center. A total of 4 focus groups were conducted with 9 patients; 2 independent groups of patients (groups A and B) were interviewed at 2 consecutive times (sessions 1 to 4), before and after their participation in a 2-week mHealth group experience consisting of (1) a competitive virtual exercise group activity (a fictitious world tour), (2) participation in a daily chat network, and (3) access to physical activity information and world tour classification feedback. We used a thematic content analysis.

RESULTS

Several physical activity levers emerged including (1) physical factors such as perception of physical benefit and previous practice, (2) psychological factors such as motivation increased by provider recommendations, (3) social factors such as group practice, and (4) organizational factors including preplanning physical activity sessions. The main barriers to physical activity identified included late effects of cancer treatment, lack of motivation, and lack of time. The lack of familiarity with connected devices was perceived as the main barrier to the use of mHealth as a means to promote physical activity. The tested mHealth group challenge was associated with several positive representations including well-being and good habit promotion and being a motivational catalyzer. Following feedback, modifications were implemented into the mHealth challenge.

CONCLUSIONS

mHealth-based, easily accessed group challenges were perceived as levers for the practice of physical activity in this population. mHealth-based group challenges should be explored as options to promote physical activity in a population with fatigue after breast cancer.

mHealth Mindfulness Intervention for Women with Moderate-to-Moderately-Severe Antenatal Depressive Symptoms: a Pilot Study Within an Integrated Health Care System

Objectives

Traditional mindfulness-based interventions have been shown to reduce depression symptoms in pregnant women, although in-person classes may pose significant accessibility barriers, particularly during the COVID-19 pandemic. Mobile technology offers greater convenience, but little is known regarding the efficacy of self-paced, mobile-delivered (mHealth) mindfulness interventions in this population. This study tested the feasibility and acceptability of offering such an intervention for pregnant women with moderate-to-moderately-severe depression symptoms.

Methods

We conducted a single-arm trial within Kaiser Permanente Northern California (KPNC). Participants were identified through KPNC’s universal perinatal depression screening program. Eligible participants included English-speaking pregnant women (<28 weeks of gestation) with moderate-to-moderately-severe depressive symptoms without a regular (<3 times/week) mindfulness/meditation practice. Participants were asked to follow a self-paced, 6-week mindfulness meditation program using a mobile app, Headspace™, 10–20 min/day. Outcome measures included feasibility, acceptability, and patient-reported outcomes (e.g., depression symptoms).

Results

Of the 27 women enrolled, 20 (74%) completed the study. Over half (55%) of participants used the app ≥50% of the days during the 6-week intervention. Responses to the semi-structured interviews indicated that women appreciated the convenience of the intervention and the ability to engage without having to attend classes or arrange childcare. We observed significant improvements in pre-postintervention scores for depression symptoms, perceived stress, sleep disturbance, and mindfulness.

Conclusions

Our study demonstrates the feasibility and acceptability of an mHealth mindfulness intervention for women with moderate-to-moderately-severe antenatal depression symptoms. The preliminary data further suggest that an efficacy trial is warranted.

Cognitive behavioral therapy or graded exercise therapy compared with usual care for severe fatigue in patients with advanced cancer during treatment: a randomized controlled trial

BACKGROUND

Cancer-related fatigue remains a prevalent and burdensome symptom experienced by patients with advanced cancer. Our aim was to assess the effects of cognitive behavioral therapy (CBT) or graded exercise therapy (GET) on fatigue in patients with advanced cancer during treatment with palliative intent.

PATIENTS AND METHODS

A randomized controlled trial was conducted from 1 January 2013 to 1 September 2017. Adult patients with locally advanced or metastatic cancer who reported severe fatigue during treatment [Checklist Individual Strength, subscale fatigue severity (CIS-fatigue) ≥35] were accrued across nine centers in The Netherlands. Patients were randomly assigned to either 12 weeks of CBT or GET, or usual care (1 : 1: 1, computer-generated sequence). Primary outcome was CIS-fatigue at 14 weeks. Secondary outcomes included fatigue measured with the European Organisation for Research and Treatment of Cancer-Quality of Life Questionnaire (EORTC-QLQ-C30), quality of life, emotional functioning, physical functioning, and functional impairments at baseline, 14, 18, and 26 weeks.

RESULTS

Among 134 participants randomized, the mean age was 63 (standard deviation 9) years and 77 (57%) were women. Common diagnoses included: breast (41%), colorectal (28%), and prostate cancer (17%). A total of 126 participants completed assessment at 14 weeks. Compared with usual care, CBT significantly reduced fatigue [difference -7.2, 97.5% confidence interval (CI) -12.7 to -1.7; P = 0.003, d = 0.7], whereas GET did not (-4.7, 97.5% CI -10.2 to 0.9; P = 0.057, d = 0.4). CBT significantly reduced EORTC-QLQ-C30 fatigue (-13.1, 95% CI -22.1 to -4.0; P = 0.005) and improved quality of life (10.2, 95% CI 2.4 to 17.9; P = 0.011) and physical functioning (7.1, 95% CI 0.5 to 13.7; P = 0.036) compared with usual care. Improvement in emotional functioning and decrease in functional impairments failed to reach significance. GET did not improve secondary outcomes compared with usual care.

CONCLUSIONS

Among advanced cancer patients with severe fatigue during treatment, a CBT intervention was more effective than usual care for reducing fatigue. Following GET, patients reported lower fatigue, but results were not significant, probably due to a smaller sample size and lower adherence than anticipated.

Therapist behaviours in a web-based mindfulness-based cognitive therapy (eMBCT) for chronic cancer-related fatigue - Analyses of e-mail correspondence

Web-based mindfulness-based cognitive therapy (eMBCT) has been found effective in decreasing fatigue severity in patients suffering from Chronic Cancer-Related Fatigue (CCRF). In web-based therapy, guidance from a therapist positively affects treatment outcome. So far, less is known about what kind of therapist behaviours contribute to treatment outcome. The present study aimed at 1) identifying therapist behaviours during eMBCT and 2) exploring whether these behaviours were correlated to a decrease in fatigue severity among patients. Qualitative content analyses were performed on 537 feedback e-mails from five therapists sent to 31 patients within a secured portal. Through content analyses, nine therapist behaviours were identified: emphatic utterances, probing self-reflection, informing, psychoeducation, task prompting, paraphrasing, task reinforcement, providing group context and alliance bolstering. Among these behaviours task prompting (19%), paraphrasing (16%) and task reinforcement (15%) were the most common. Linear regression analyses showed a significant association between informing and task prompting on the one hand and a decrease in fatigue severity on the other. Multivariate analysis indicated that informing and task prompting jointly explain the decrease in fatigue. These findings underline the importance for therapists to provide patients with sufficient information and to encourage them to do the exercises.

Mindfulness-Based Programs for Patients With Cancer via eHealth and Mobile Health: Systematic Review and Synthesis of Quantitative Research

Background

eHealth mindfulness-based programs (eMBPs) are on the rise in complex oncology and palliative care. However, we are still at the beginning of answering the questions of how effective eMBPs are and for whom, and what kinds of delivery modes are the most efficient.

Objective

This systematic review aims to examine the feasibility and efficacy of eMBPs in improving the mental health and well-being of patients with cancer, to describe intervention characteristics and delivery modes of these programs, and to summarize the results of the included studies in terms of moderators, mediators, and predictors of efficacy, adherence, and attrition.

Methods

In total, 4 databases (PubMed, PsycINFO, Scopus, and Web of Knowledge) were searched using relevant search terms (eg, mindfulness, program, eHealth, neoplasm) and their variations. No restrictions were imposed on language or publication type. The results of the efficacy of eMBPs were synthesized through the summarizing effect estimates method.

Results

A total of 29 published papers describing 24 original studies were included in this review. In general, the results indicate that eMBPs have the potential to reduce the levels of stress, anxiety, depression, fatigue, sleep problems, and pain, and improve the levels of mindfulness, posttraumatic growth, and some parameters of general health. The largest median of Cohen d effect sizes were observed in reducing anxiety and depression (within-subject: median −0.38, IQR −0.62 to −0.27; between-group: median −0.42, IQR −0.58 to −0.22) and facilitating posttraumatic growth (within-subject: median 0.42, IQR 0.35 to 0.48; between-group: median 0.32, IQR 0.22 to 0.39). The efficacy of eMBP may be comparable with that of parallel, face-to-face MBPs in some cases. All studies that evaluated the feasibility of eMBPs reported that they are feasible for patients with cancer. Potential moderators, mediators, and predictors of the efficacy, attrition, and adherence of eMBPs are discussed.

Conclusions

Although the effects of the reviewed studies were highly heterogeneous, the review provides evidence that eMBPs are an appropriate way for mindfulness practice to be delivered to patients with cancer. Thus far, existing eMBPs have mostly attempted to convert proven face-to-face mindfulness programs to the eHealth mode. They have not yet fully exploited the potential of eHealth technology.

A Mobile Health Mindfulness Intervention for Women With Moderate to Moderately Severe Postpartum Depressive Symptoms: Feasibility Study

BACKGROUND

Approximately 20% of women suffer from postpartum depression (PPD). Due to barriers such as limited access to care, half of the women with PPD do not receive treatment. Therefore, it is critical to identify effective and scalable interventions. Traditional mindfulness programs have been effective in reducing depressive symptoms, however access remains a barrier. A self-paced mobile health (mHealth) mindfulness program may fit the lifestyle of busy mothers who are unable to attend in-person classes. However, little is known regarding the feasibility or efficacy of mHealth mindfulness interventions in postpartum women with depressive symptoms.

OBJECTIVE

This study aims to assess the feasibility, acceptability, and preliminary efficacy of an mHealth mindfulness intervention for postpartum women with moderate to moderately severe depressive symptoms.

METHODS

We conducted a single-arm feasibility trial of an mHealth mindfulness intervention within Kaiser Permanente Northern California (KPNC), a large integrated health care system. Participants were identified through clinician referral and electronic health records via KPNC's universal perinatal depression screening program and recruited by the study team. Inclusion criteria included the following: English-speaking, up to 6 months postpartum with a Patient Health Questionnaire (PHQ-8) score of 10 to 19, and no regular mindfulness/meditation practice. Participants were asked to use a mindfulness app, Headspace, 10 to 20 min/day for 6 weeks. Baseline and postintervention surveys captured data on patient-reported outcomes (depression and stress symptoms, sleep quality, and mindfulness). Semistructured interviews captured acceptability. Retention and adherence were used to assess feasibility.

RESULTS

Of the 115 women who were contacted and met the eligibility criteria or declined participation before eligibility assessment, 27 (23%) were enrolled. In addition, 70% (19/27) completed the study. The mean age of participants was 31 years (SD 5.2), 30% (8/27) were non-Hispanic White, and, on average, participants were 12.3 weeks postpartum (SD 5.7). Of the women who completed the study, 100% (19/19) used the Headspace app at least once, and nearly half (9/19, 47%) used the app on ≥50% of the days during the 6-week intervention period. Of the 16 participants who completed the postintervention interview, 69% (11/16) reported that they were very or extremely satisfied with the app. Interviews indicated that women appreciated the variety of meditations and felt that the program led to reduced anxiety and improved sleep. Significant improvements in pre- and postintervention scores were observed for depressive symptoms (PHQ-8: -3.8, P=.004), perceived stress (10-item Perceived Stress Scale: -6.0, P=.005), and sleep quality (Pittsburgh Sleep Quality Index: -2.1, P=.02, indicating less sleep disturbance). Improvements in mindfulness were also significant (Five Facet Mindfulness Questionnaire-Short Form: 10.9, P=.01).

CONCLUSIONS

An mHealth mindfulness intervention for postpartum women with moderate to moderately severe depressive symptoms is feasible and acceptable. An efficacy trial is warranted.

Beating cancer-related fatigue with the Untire mobile app: Results from a waiting-list randomized controlled trial

OBJECTIVE

This waiting-list randomized controlled trial examined the effectiveness of a self-management mHealth app in improving fatigue and quality of life (QoL) in cancer patients and survivors.

METHODS

Persons with cancer-related fatigue (CRF) were recruited across four English speaking countries, via social media, and randomized into intervention (n = 519) and control (n = 280) groups. Whereas the intervention group received immediate access to the Untire app, the control group received access only after 12-weeks. Primary outcomes fatigue severity and interference, and secondary outcome QoL were assessed at baseline, 4, 8, and 12-weeks. We ran generalized linear mixed models for all outcomes to determine the effects of app access (yes/no), over 12-weeks, following the intention-to-treat principle.

RESULTS

Compared with the control group, the intervention group showed significantly larger improvements in fatigue severity (d = 0.40), fatigue interference (d = 0.35), and overall QoL on average (d = 0.32) (P's < .01), but not for overall QoL in the past week (P = .07). Sensitivity analyses indicated that participants with medium or high app use benefited most when compared with nonusers and control participants (P's ≤ .02). The intervention effect on fatigue interference was slightly stronger in younger participants (≤56 vs. >56). Effects did not depend on education and cancer status. Reliable change analyses indicated that significantly more people showed full recovery for fatigue in the intervention vs the control group (P's = .02).

CONCLUSIONS

The Untire app can be an effective mHealth solution for cancer patients and survivors with moderate to severe CRF.

Predictors and Effects of Usage of an Online Mindfulness Intervention for Distressed Cancer Patients: Usability Study

Background

One in three cancer patients experience high psychological distress. Mindfulness-based interventions are effective in reducing psychological distress in this patient group. However, these interventions lack availability and flexibility, which may compromise participation in the intervention for cancer patients experiencing late symptoms like fatigue or pain. Therefore, mindfulness-based interventions are increasingly offered via the internet. However, little is known about the usage of these online mindfulness-based interventions.

Objective

The aim of this study was to (1) predict uptake of and adherence to online mindfulness-based cognitive therapy (eMBCT) using baseline patient characteristics (demographic, cancer-related, personality, and psychological variables) and (2) examine the relations between adherence and treatment outcomes in eMBCT for cancer patients.

Methods

A total of 125 cancer patients were assigned to eMBCT in a parent randomized controlled trial comparing MBCT and eMBCT with treatment as usual in distressed cancer patients. Various usage measures of eMBCT were automatically tracked within the online program. Based on activity of use, participants were classified as nonusers, minimal users, low users, and intended users. Questionnaires were used to assess baseline characteristics (preintervention) and outcomes (pre- and postintervention). To answer the research questions, data were analyzed with t tests, χ² tests, and linear regression models.

Results

Based on weekly activity, participants were classified as nonusers (n=17, 13.6%), who completed no exercises in MBCT; minimal users (n=31, 24.8%), who completed at least one exercise of one to three sessions; low users (n=12, 9.6%), who completed at least one exercise of four to seven sessions; and intended users (n=65, 52.0%), who completed at least one exercise of eight to nine sessions. Nonusers had more fear of cancer recurrence at baseline than users (uptake), and intended users were more conscientious than minimal and low users (adherence). Intended users reported a larger reduction in psychological distress and more improvement of positive mental health (ie, emotional, psychological, and social well-being) after the intervention than other participants.

Conclusions

This study showed that adherence was related to improved patient outcomes. Patients with strong fear of recurrence or low levels of conscientiousness should receive extra attention, as they are less likely to respectively start or complete eMBCT. Future research may focus on the development of flexible and adaptive eMBCT programs to fit individual needs.

Integrative Therapies for Cancer-Related Fatigue

Cancer-related fatigue (CRF) is a common symptom for which cancer patients often use integrative and integrative therapies; however, evidence supporting these therapies is limited. The aim of this review is to provide evidence-based recommendations for integrative interventions during and after cancer treatment for CRF. These recommendations are based on a systematic literature review from 1990 through 2019. Cognitive behavior therapy plus hypnosis and American ginseng can be considered during active treatment, and acupressure, mindfulness-based cognitive therapy, and qigong/tai chi easy can be considered during posttreatment. Coenzyme Q10 and L-carnitine are not recommended during active-treatment. All other integrative therapies for CRF had insufficient evidence to make a recommendation. While there is increasing evidence for integrative therapies for CRF, because of lack of rigorous trials and replication, no therapies could be definitively recommended. Further rigorously designed integrative therapy research is needed and should consider implementation and dissemination.

Post-exertional Malaise in People With Chronic Cancer-Related Fatigue

CONTEXT

Cancer-related fatigue (CRF) is a distressing and persistent sense of tiredness or exhaustion that interferes with usual functioning. Chronic CRF continues for months after curative cancer treatment is complete. Post-exertional malaise (PEM) is a worsening of symptoms after physical or mental activity, with limited investigations in people with chronic CRF.

OBJECTIVES

The purpose of this study was to identify and describe self-reported incidences of PEM in people with chronic CRF.

METHODS

Participants (n = 18) were eligible if they scored ≤34 on the Functional Assessment of Chronic Illness Therapy-Fatigue scale and had a cancer-related onset of fatigue. Participants completed a brief questionnaire to assess PEM during a six-month time frame (the DePaul Symptom Questionnaire-PEM). In addition, a maximal exercise test was used to investigate self-reported symptom exacerbation (via an open-ended questionnaire) after strenuous physical exertion.

RESULTS

On the DePaul Symptom Questionnaire-PEM, three participants met previously defined scoring criteria, which included experiencing moderate to very severe symptoms at least half of the time, worsening of fatigue after minimal effort, plus a recovery duration of >24 hours. Content analysis of responses to open-ended questionnaires identified five people who experienced a delayed recovery and symptoms of PEM after maximal exercise.

CONCLUSION

A subset of people with chronic CRF (up to 33% in this sample) may experience PEM. Exercise specialists and health care professionals working with people with chronic CRF must be aware that PEM may be an issue. Symptom exacerbation after exercise should be monitored, and exercise should be tailored and adapted to limit the potential for harm.

Exploring the interconnectedness of fatigue, depression, anxiety and potential risk and protective factors in cancer patients: a network approach

Researchers have extensively studied fatigue, depression and anxiety in cancer patients. Several risk and protective factors have been identified for these symptoms. As most studies address these constructs, independently from other symptoms and potential risk and protective factors, more insight into the complex relationships among these constructs is needed. This study used the multivariate network approach to gain a better understanding of how patients' symptoms and risk and protective factors (i.e. physical symptoms, social withdrawal, illness cognitions, goal adjustment and partner support) are interconnected. We used cross-sectional data from a sample of cancer patients seeking psychological care (n = 342). Using network modelling, the relationships among symptoms of fatigue, depression and anxiety, and potential risk and protective factors were explored. Additionally, centrality (i.e. the number and strength of connections of a construct) and stability of the network were explored. Among risk factors, the relationship of helplessness and physical symptoms with fatigue stood out as they were stronger than most other connections in the network. Among protective factors, illness acceptance was most centrally embedded within the network, indicating it had more and stronger connections than most other variables in the network. The network identified key connections with risk factors (helplessness, physical symptoms) and a key protective factor (acceptance) at the group level. Longitudinal studies should explore these risk and protective factors in individual dynamic networks to further investigate their causal role and the extent to which such networks can inform us on what treatment would be most suitable for the individual cancer patient.
