A systematic scoping review of post-treatment lifestyle interventions for adult cancer survivors and family members

Living together-does it help or hinder the pursuit of a healthful diet, physical activity, and weight loss among cancer survivors and their chosen partners?

PURPOSE

Parental or spousal cohabitating relationships are often targeted in behavioral interventions, but the contribution of cohabitation is poorly understood. This study explored whether cohabitation status moderated the impact of social cognitive theory constructs on adiposity, diet, and exercise in a dyadic, web-based weight loss intervention among cancer survivors and their chosen partners.

METHODS

The 24-week weight loss intervention was conducted among 56 dyads, comprised of a cancer survivor and their chosen partner (n = 112). Baseline and 6-month data on social cognitive theory constructs (self-efficacy, social support, and perceived barriers), and study outcomes of adiposity (weight and waist circumference), diet (calories and diet quality), and moderate-to-vigorous physical activity (MVPA) were used to perform moderated-mediation analyses among cohabitating (n = 25) versus non-cohabitating (n = 31) dyads.

RESULTS

The intervention was positively associated with dietary social support (path a1: 0.36, 95% CI [0.083, 0.659]) and inversely associated with perceived dietary barriers (path a1: - 10.57, 95% CI [- 19.109, - 3.091]) and perceived exercise barriers (path a1: - 11.29, 95% CI [- 22.098, - 3.500]) among those who did not cohabitate (effects not observed among cohabitating pairs). The intervention's mediating effects through perceived barriers on weight (indirect effect (ab): - 2.21, 95% CI [- 4.794, - 0.548]), waist circumference (ab: - 1.13, 95% CI [- 2.452, - 0.171]), caloric intake (ab: - 5.09 (2.86), 95% CI [- 12.602, - 0.709]), and self-reported MVPA (ab: 0.29 (0.18), 95% CI [0.019, 0.754]) also were stronger among non-cohabitating pairs.

CONCLUSIONS

These findings suggest that social support partners outside the home substantially enhance intervention impact, though relationship quality and gender dynamics warrant further exploration.

Changes in rural caregivers' health behaviors while supporting someone with cancer: A qualitative study

PURPOSE

Caring for someone with cancer has a significant impact on usual routines, including caregivers' ability to maintain their own health and wellbeing. Caregivers living in rural areas face additional challenges in supporting someone with cancer, and little is known about the impact of caregiving on the health behaviors of rural caregivers. Therefore, this study explored how caring for someone with cancer affected rural caregivers' health behaviors.

METHODS

Through semi-structured interviews, 20 rural caregivers described changes in their health behaviors while caring for someone with cancer and the factors underlying these changes. Specific prompts were provided for diet, physical activity, alcohol, smoking, sleep, social connection and leisure, and accessing health care when needed. Interviews were audio-recorded and transcribed verbatim. Content analysis was used to identify changes in health behaviors and the factors underlying these changes. The factors identified were mapped to the socioecological framework, identifying areas for intervention across multiple levels (individual, interpersonal, organizational, community, and policy).

RESULTS

Rural caregivers reported both positive and negative changes to their diet, physical activity, alcohol, and smoking. Sleep, social connection and leisure, and accessing health care were negatively impacted since becoming a caregiver.

CONCLUSIONS

Designing interventions to address rural caregivers' coping strategies, reduce carer burden and fatigue, improve access to cooking and exercise facilities and social support while away from home, reduce the need to travel for treatment, and increase the financial support available could yield widespread benefits for supporting the health and wellbeing of rural caregivers.

Feasibility, Adherence, and Effectiveness of Blended Psychotherapy for Severe Mental Illnesses: Scoping Review

BACKGROUND

Blended psychotherapy (bPT) combines face-to-face psychotherapy with digital interventions to enhance the effectiveness of mental health treatment. The feasibility and effectiveness of bPT have been demonstrated for various mental health issues, although primarily for patients with higher levels of functioning.

OBJECTIVE

This scoping review aims to investigate the feasibility, adherence, and effectiveness of bPT for the treatment of patients with severe mental illnesses (SMIs).

METHODS

Following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines, we conducted searches in PubMed, MEDLINE, Embase, PsycINFO, and PsycArticles for studies published until March 23, 2023.

RESULTS

Out of 587 screened papers, we incorporated 25 studies encompassing 23 bPT interventions, involving a total of 2554 patients with SMI. The intervention formats and research designs exhibited significant variation. Our findings offer preliminary evidence supporting the feasibility of bPT for SMI, although there is limited research on adherence. Nevertheless, the summarized studies indicated promising attrition rates, spanning from 0% to 37%, implying a potential beneficial impact of bPT on adherence to SMI treatment. The quantity of evidence on the effects of bPT for SMI was limited and challenging to generalize. Among the 15 controlled trials, 4 concluded that bPT interventions were effective compared with controls. However, it is noteworthy that 2 of these studies used the same study population, and the control groups exhibited significant variations.

CONCLUSIONS

Overall, our review suggests that while bPT appears promising as a treatment method, further research is necessary to establish its effectiveness for SMI. We discuss considerations for clinical implementation, directions, and future research.

A Systematic Review of Dietary Interventions for Cancer Survivors and Their Families or Caregivers

Family or caregiver engagement has the potential to support healthy dietary changes among cancer survivors. However, little is known about these family- or caregiver-involved dietary interventions and their effects. This systematic review aimed to identify the behavior change techniques (BCTs) used in dietary interventions for cancer survivors and their families or caregivers and to synthesize intervention effects on dietary and health outcomes. Following the PRISMA guidelines, we conducted systematic searches in three databases and identified 12 trials (16 peer-reviewed manuscripts) for inclusion in this review. Data were extracted from these manuscripts and the BCT taxonomy was used to identify the BCTs. A total of 38 BCTs were identified from 12 trials, 13 of which were used in at least half of the 12 trials. Ten studies reported significant intervention effects on health outcomes (e.g., adiposity) and six suggested significant improvements in dietary behaviors (e.g., fruit and vegetable intake). Overall, this review found that family- or caregiver-involved interventions for cancer survivors significantly improved dietary and health outcomes. Future research should identify BCTs particularly for dietary changes and develop effective dyadic strategies to facilitate diet-related interactions between survivors and their families or caregivers to enhance their engagement in healthy diets.

A Scoping Review to Explore the Potential Benefits of Nutrition Interventions for Latino/a Adult Cancer Survivors in the US

Despite evidence for the role of healthy diets in preventing cancer, little is known about how nutrition can support positive health outcomes after a cancer diagnosis for Latino/a cancer survivors in the United States (U.S.). The purpose of this scoping review is to understand the potential benefits of nutrition interventions in supporting healthy survivorship among Latino/a cancer survivors in the U.S. A team compiled, evaluated, and summarized the available evidence. Potentially relevant studies were identified from a comprehensive search of peer-reviewed databases and the gray literature. Eligible studies included Latino/a adult cancer survivors with a nutrition education, dietary change, or behavioral intervention; and a nutrition-related health outcome. Data were extracted and summarized using tables. The review included 10 randomized controlled trials, with samples or subsamples of Latino/a cancer survivors. Interventions mostly focused on breast cancer survivors. The results showed some evidence that dietary behaviors, like fruit and vegetable intake, were related to positive outcomes, like a decreased risk of cancer (through changes in DNA methylation), decreased risk breast cancer recurrence (through changes in inflammatory biomarkers), or improved perception of health status. The findings highlight a need for community-engaged and culturally relevant nutrition interventions for Latino/a adults, especially for rural communities; and innovative intervention approaches, including m/ehealth approaches with long-term follow-up.

Dietary Barriers Appear to Influence the Effects of a Dyadic Web-Based Lifestyle Intervention on Caloric Intake and Adiposity: A Mediation Analysis of the DUET Trial

Mechanisms that explain behavior change within web-based lifestyle interventions are not well-studied. This secondary analysis explores whether the effects of the DUET web-based lifestyle intervention on diet, physical activity, and/or adiposity are mediated through changes in self-efficacy, social support, and perceived barriers (key constructs of social cognitive theory). Data on mediators, diet quality, caloric intake, moderate-to-vigorous physical activity (MVPA), weight, and waist circumference (WC) were analyzed from 112 cancer survivors and their partners enrolled in the DUET intervention. Mediation analyses were performed using Mplus to execute regression analyses and determine associations. Mediation analyses supported an effect of the intervention on caloric intake (-3.52, 95% CI [-8.08 to -0.84]), weight (-1.60, CI [-3.84 to -0.47]), and WC (-0.83, CI [-1.77 to -0.18]), interpreting these negative associations as intervention induced reductions in dietary barriers. Higher social support was significantly and positively associated with, but not a mediator for, improvements in self-reported and accelerometry-measured MVPA (b = 0.69, CI [0.19, 1.24]) and (b = 0.55, CI [0.15, 1.00]), respectively. Self-efficacy did not appear to mediate the intervention's effects. Findings suggest that the effects of the DUET intervention on diet and adiposity stem from reducing perceived barriers to a healthful, low-calorie diet.

Motivational interviewing interventions aiming to improve health behaviors among cancer survivors: a systematic scoping review

PURPOSE

The scoping review aimed to map out the literature on the utilization of motivational interviewing (MI) to improve health behaviors (i.e., physical activity, nutrition) in adult cancer survivors.

METHODS

This scoping review was conducted following the methods and protocol outlined by the Joanna Briggs Institute Methods Manual. Five databases, including PubMed, CINAHL, Web of Science, and SPORTDiscus, were searched in February 2022 to identify MI interventions to improve health behaviors among cancer survivors.

RESULTS

The review included 22 interventions mostly designed to optimize exercise/physical activity (50%). The number of sessions ranged from 2 to 19, and most MI sessions were offered via telephone calls combined with face-to-face sessions (31.8%). Of the interventions, 81.8% improved at least one outcome measurement. Most studies used principles of MI such as empathy expression, developing discrepancy, roll with resistance, and supporting self-efficacy.

CONCLUSION

The use of MI appears to have the potential to improve health behaviors in various settings for individuals on different cancer care trajectories.

IMPLICATIONS FOR CANCER SURVIVORS

Healthcare providers can use MI to support physical activity and a healthy diet. Future research should focus on providing evidence on the utilization of MI with minimum standards and longitudinal outcome assessment for developing and maintaining sustainable healthy behaviors.

Social Support in a Cancer Patient-Informal Caregiver Dyad: A Scoping Review

Social support that includes promoting healthy behaviours throughout the oncology pathway, from diagnosis to treatment to survival, can leverage existing support networks and improve the health of patients and family members in supportive roles. This scoping review aimed to identify and summarise the impact of social support on the patient-informal caregiver relationship during cancer treatment. Inclusion criteria were related to a high focus on dyadic cancer patient-informal caregiver relationships, considering a population of adult cancer patients in active hospitalisation on an oncology ward, and published between 2012 and 2022 to get a portrait of the literature that might influence the current practice. A systematic search using the "Population, Concept, and Context" framework was performed in PubMed, Web of Science, SCOPUS, EBSCO Medline, and CINAHL: 13 articles from the 16,425 pre-qualified articles published between 2012 and 2022. The narrative synthesis of the included studies highlighted that social support, encompassing its different forms within the context of dyads, is frequently associated with an enhanced quality of life, hope, and resilience of both patients and informal caregivers. However, it is important to recognize that the support interventions provided to patients, particularly caregivers, were frequently not thoroughly evaluated or explained, and the sample sizes of the included studies were often limited. Therefore, this review clarified the social and clinical potential of social support for the patient-informal caregiver relationship, paving the way for future robust studies that require to be powered and designed on specific outcomes to allow informing the practice on specific recommendations.

Perceived Provision of Perioperative Information and Care by Patients Who Have Undergone Surgery for Colorectal Cancer: A Cross-Sectional Study

BACKGROUND

Active patient participation in preparation and recovery from colorectal cancer surgery can be facilitated by timely information and care and may improve patient wellbeing and reduce hospitalizations; Methods: We aimed to identify gaps in perioperative information and care by asking colorectal cancer surgical patients to retrospectively report on their perceptions of care via a cross-sectional survey; Results: Overall, 179 (64% consent rate) patients completed one of two 64-item surveys exploring their views of 'optimal care' or their experiences of 'actual care'. In total, 41 (64%) aspects of care were endorsed as optimal. Of these, almost three-quarters (73%) were received by most patients (80% or more). Gaps in care were identified from discrepancies in the endorsement of optimal versus actual survey items. Of the 41 items identified as representing 'optimal care', 11 items were received by fewer than 80% of patients, including the provision of information about the impact of surgical wait-times on cancer cure (69%); pre-habilitation behaviors to improve health (75%); the type of questions to ask the health care team (74%); impact of pain medications on bowel movements (73%); how to obtain medical supplies for self-care at home (67%); dietary or exercise advice after discharge (25-31%); and emotional advice after discharge (44%).

CONCLUSIONS

These gaps represent patient-centered priorities and targets for supportive interventions.

A Model of Social Support for a Patient–Informal Caregiver Dyad

Background

Close persons (informal caregivers) are the most important providers of support indicated by cancer patients. Cancer affects couples as a codependent system. The aim of this study was to investigate the factors influencing the multidimensional aspect of social support in a cancer patient–informal caregiver dyad.

Methods

The research project was cross-sectional. The diagnostic survey method and the survey technique were used. The study was conducted using standardised research tools: BSSS, POS, SSCS, TIPI, ET, SPT, and the authors' own tool for sociodemographic assessment.

Results

Patients and caregivers experienced injustice, exclusion, and a sense of loss with a similar intensity. Statistically significant differences between the examined patients and their caregivers were obtained for the support currently received (p < 0.01), emotional support (p < 0.05), and the general level of protective buffering support (p < 0.001). A higher level of information support for caregivers increases the need for support and a sense of support for patients.

Conclusion

The quality of functioning and mental well-being of patients is directly influenced by the way their caregivers experience the situation of caring for them; negative or positive states of caregivers, affecting the condition of patients, may affect the course of treatment and contribute to or delay the improvement of the state of health. The subjective sense of support in patients during treatment depends on the need for help that is shown to their caregivers. The sense of support variable is subjective and sometimes disproportionate to the support received and given. Therefore, both the patient and their loved one should be provided with care during the treatment process. In the treatment process, both patients and their caregivers need more protective buffering support that allows them to overcome difficulties related to stress, anxiety, and insecurity, thus weakening their negative effects rather than functional support: emotional, information, instrumental, or material.

Support-seeking by cancer caregivers living in rural Australia

OBJECTIVE

Rural cancer caregivers report poor wellbeing and high unmet needs for support. This study investigates sources of support sought by cancer caregivers living in rural Australia, and factors associated with support-seeking.

METHODS

Informal caregivers of people with cancer completed a questionnaire assessing sociodemographic characteristics, caregiver factors and support-seeking. Descriptive statistics, bivariate analyses and logistic regression were used to identify common sources of support and factors associated with support-seeking. Alluvial and radar plots were used to identify and describe support-seeking profiles.

FINDINGS

Of 244 rural caregivers, 64% reported seeking support for themselves, 72% for the cancer patient, and 22% did not seek any support. The most common sources of support were general practitioners and online. Higher caregiver burden, higher income, caring for someone with anxiety/depression or caring for someone who has difficulty completing their usual activities were associated with seeking support from a greater number of sources. The 'No support-seekers' profile had the highest proportions of caregivers who were male, caring for someone <12 months post-diagnosis and lower income earners.

CONCLUSIONS

Many rural caregivers seek support for themselves and the cancer patient, commonly from medical and online sources.

IMPLICATIONS FOR PUBLIC HEALTH

Further work may be needed to reduce caregiver burden and support caregivers who are male, caring for someone recently diagnosed, and those with lower incomes.

A qualitative exploration of women's perspectives and acceptability of including new cancer awareness information in all-clear breast or cervical screening results

Objective

This study explored women's perspectives on the acceptability of including new cancer information with an all‐clear breast or cervical screening result letter (using ovarian cancer as a case study).

Methods

In 2016, six focus group discussions were conducted with women aged 25–70 years old, eligible for invitation to the NHS breast or cervical screening programme and resident in England. The focus groups lasted 60–90 min and were held in community venues. Data were analysed using thematic analysis.

Results

Thirty‐eight women aged 25–67 years old participated in the focus groups. Data analysis yielded six descriptive themes: general cancer awareness, taking advantage of a ‘teachable moment’, a double‐edge sword, barriers to accepting and using new cancer information, motivators for accepting and using new cancer information and wider strategies to increase cancer awareness in women. Women welcomed the inclusion of new cancer information in all‐clear screening results but highlighted pertinent lessons to be considered to maximise the usefulness of the approach.

Conclusion

While women perceived this approach as acceptable, it is pertinent to note the potential of the new cancer information to stimulate anxiety and potentially widen inequalities by excluding non‐attenders at screening programmes. Specific complementary and tailored approaches are necessary to mitigate these limitations.

Healthy Moves to Improve Lifestyle Behaviors of Cancer Survivors and Their Spouses: Feasibility and Preliminary Results of Intervention Efficacy

Spouses offer a primary source of support and may provide critical assistance for behavior change. A diet-exercise intervention previously found efficacious in improving cancer survivors' lifestyle behaviors was adapted to utilize a couples-based approach. The aims were to test the feasibility of this couples-based (CB) intervention and compare its efficacy to the same program delivered to the survivor-only (SO). Twenty-two survivor-spouse couples completed baseline assessments and were randomized to the CB or SO interventions. The study surpassed feasibility benchmarks; 91% of survivors and 86% of spouses completed a 6-month follow-up. Survivors and spouses attended 94% and 91% of sessions, respectively. The SO survivors showed significant improvements on the 30-s chair stand and arm curl tests, weight, and fruit and vegetable (F and V) consumption. The CB survivors showed significant improvements on the 6-min walk and 2-min step tests, body weight, and fat and F and V consumption. Improvement in the 30-s chair stand and arm curl tests was significantly better for SO survivors. The SO spouses showed no significant changes in outcome measures, but the CB spouses showed significant improvements in moderate-to-strenuous physical activity, weight, and fat and F and V consumption. Weight loss was significantly greater in CB spouses compared to SO spouses. Findings demonstrate feasibility, warranting further investigation of CB approaches to promote lifestyle change among cancer survivors and spouses.
