Study protocol for a feasibility study of an internet-administered, guided, CBT-based, self-help intervention (ENGAGE) for parents of children previously treated for cancer

Behavioural change for Parkinson's Disease: A randomised controlled feasibility study to promote physical activity and exercise adherence among people with Parkinson's: study protocol

Background

Parkinson's is a common progressive neurological condition characterized by motor and non-motor deficits. Physical activity and exercise can improve health, but many people with Parkinson's (PwP) have trouble reaching the recommended dosage. Our recent literature review found improvements in exercise adherence with behavioural change interventions, but it remains unclear which are most effective. Further qualitative research and patient and public involvement has informed a novel behavioural change intervention to be tested alongside an existing exercise program.

Objective

To examine the feasibility of behavioural change techniques delivered alongside an exercise programme to improve physical activity, function, and self-efficacy in PwP (and study procedures) to inform a future pilot RCT trial.

Methods

A parallel-arm single blinded randomised feasibility study. Twenty participants with Parkinson's (Hoehn and Yahr stage 1-3) will be recruited from a physiotherapy primary-care waiting list. Following written consent, and baseline assessment, the participants will be randomly allocated to the intervention (n=10) or the control group (n=10). Both groups will receive usual care, which includes a weekly program of a multidisciplinary education, a supervised exercise class and a prescribed home exercise program. The intervention group will receive additional behavioural change techniques, targeting behaviour regulation, belief about capabilities and social influences. Class and home exercise adherence, behavioural component uptake and adherence, and negative events will be recorded. Outcomes will include enrolment and maintenance rates, physical function, falls, physical activity, and exercise self-efficacy measured pre- and post- the 12-week program (in-person). Surveys will be used to compare experiences and satisfaction between groups. Exit interviews will be completed with the intervention group only, exploring their experience of the behavioural change techniques.

Discussion

The results will help inform a future pilot RCT, based on the intervention acceptability, consent rate, maintenance, and protocol integrity.

Consolidated guidance for behavioral intervention pilot and feasibility studies

BACKGROUND

In the behavioral sciences, conducting pilot and/or feasibility studies (PFS) is a key step that provides essential information used to inform the design, conduct, and implementation of a larger-scale trial. There are more than 160 published guidelines, reporting checklists, frameworks, and recommendations related to PFS. All of these publications offer some form of guidance on PFS, but many focus on one or a few topics. This makes it difficult for researchers wanting to gain a broader understanding of all the relevant and important aspects of PFS and requires them to seek out multiple sources of information, which increases the risk of missing key considerations to incorporate into their PFS. The purpose of this study was to develop a consolidated set of considerations for the design, conduct, implementation, and reporting of PFS for interventions conducted in the behavioral sciences.

METHODS

To develop this consolidation, we undertook a review of the published guidance on PFS in combination with expert consensus (via a Delphi study) from the authors who wrote such guidance to inform the identified considerations. A total of 161 PFS-related guidelines, checklists, frameworks, and recommendations were identified via a review of recently published behavioral intervention PFS and backward/forward citation tracking of a well-known PFS literature (e.g., CONSORT Ext. for PFS). Authors of all 161 PFS publications were invited to complete a three-round Delphi survey, which was used to guide the creation of a consolidated list of considerations to guide the design, conduct, and reporting of PFS conducted by researchers in the behavioral sciences.

RESULTS

A total of 496 authors were invited to take part in the three-round Delphi survey (round 1, N = 46; round 2, N = 24; round 3, N = 22). A set of twenty considerations, broadly categorized into six themes (intervention design, study design, conduct of trial, implementation of intervention, statistical analysis, and reporting) were generated from a review of the 161 PFS-related publications as well as a synthesis of feedback from the three-round Delphi process. These 20 considerations are presented alongside a supporting narrative for each consideration as well as a crosswalk of all 161 publications aligned with each consideration for further reading.

CONCLUSION

We leveraged expert opinion from researchers who have published PFS-related guidelines, checklists, frameworks, and recommendations on a wide range of topics and distilled this knowledge into a valuable and universal resource for researchers conducting PFS. Researchers may use these considerations alongside the previously published literature to guide decisions about all aspects of PFS, with the hope of creating and disseminating interventions with broad public health impact.

E-therapists' views on the acceptability and feasibility of an internet-administered, guided, low-intensity cognitive behavioural therapy intervention for parents of children treated for cancer: A qualitative study

Background

Childhood cancer treatment completion can be a period of vulnerability for parents and is associated with mental health difficulties such as depression and anxiety. We developed an internet-administered, guided, low-intensity cognitive behavioural therapy-based self-help intervention (EJDeR) for parents delivered on the U-CARE-portal (Portal). The acceptability and feasibility of EJDeR and study procedures were examined using a single-arm feasibility trial (ENGAGE). Results indicated that EJDeR and ENGAGE study procedures are acceptable and feasible, however, a need for clinical and technical modifications to EJDeR and refinements to ENGAGE study procedures was identified.

Objectives

This study aimed to explore the acceptability and feasibility of EJDeR and ENGAGE study procedures from the perspective of e-therapists to inform clinical and technical modifications to EJDeR and refinements to study procedures prior to progression to a superiority randomised controlled trial.

Methods

We conducted semi-structured interviews with 10 e-therapists. Data were analysed using manifest content analysis.

Results

We identified three categories relating to the acceptability and feasibility of EJDeR: (a) Support to e-therapists (subcategories: Clinical supervision and Technical difficulties); (b) Guidance to parents (subcategories: Support protocols and Synchronous communication); and (c) Content (subcategories: Relevancy of the intervention and Pacing of the intervention). We identified four categories relating to the acceptability and feasibility of study procedures: (a) Recruitment and training of e-therapists (subcategories: Definition of the role and Training program); (b) Retention of parents (subcategories: Parent suitability and screening and Frequency of weekly Portal assessments); (c) Retention of e-therapists (subcategories: Administrative requirements and Communication with the research team); and (d) The Portal.

Conclusions

EJDeR and study procedures were considered acceptable and feasible, however, clinical and technical modifications and refinements to study procedures were suggested to enhance acceptability and feasibility. Results may also inform implementation considerations for both EJDeR and other similar digital psychological interventions.

Internet-administered, low-intensity cognitive behavioral therapy for parents of children treated for cancer: A feasibility trial (ENGAGE)

BACKGROUND

Parents of children treated for cancer may experience mental health difficulties, such as depression and anxiety. There is a lack of evidence-based psychological interventions for parents, with psychological support needs unmet. An internet-administered, guided, low-intensity cognitive behavioral therapy-based (LICBT) self-help intervention may provide a solution.

METHODS

The feasibility and acceptability of such an intervention was examined using a single-arm feasibility trial (ENGAGE). Primary objectives examined: (1) estimates of recruitment and retention rates; (2) feasibility and acceptability of data collection instruments and procedures; and (3) intervention feasibility and acceptability. Clinical outcomes were collected at baseline, post-treatment (12 weeks), and follow-up (6 months).

RESULTS

The following progression criteria were met: sample size was exceeded within 5 months, with 11.0% enrolled of total population invited, study dropout rate was 24.0%, intervention dropout was 23.6%, missing data remained at ≤10% per measure, and no substantial negative consequences related to participation were reported. Intervention adherence was slightly lower than progression criteria (47.9%).

CONCLUSION

Findings suggest an internet-administered, guided, LICBT self-help intervention may represent a feasible and acceptable solution for parents of children treated for cancer. With minor study protocol and intervention modifications, progression to a pilot randomized controlled trial (RCT) and subsequent superiority RCT is warranted.

Parental Distress in Pediatric Inflammatory Bowel Diseases: Associations With Time From Diagnosis, Disease Activity, and Demographic Factors

Background

There are limited studies examining caregiver distress when raising a child with inflammatory bowel disease (IBD). The aim of this study was to investigate the occurrence of symptoms of distress (anxiety, depression, and post-traumatic stress disorder [PTSD]) among parents with children with IBD and associations with disease severity, time from diagnosis, and demographic factors.

Methods

We conducted a cross-sectional study with parents of children (2-17 years) diagnosed with IBD. There were 2 cohorts: (1) recently diagnosed cohort (<6 months from diagnosis); (2) established diagnosis cohort (>1 year from diagnosis). Parents completed measures of anxiety, depression, and PTSD, while children completed surveys on the symptoms of their IBD.

Results

Fifty-two parents in the recently diagnosed cohort and 103 parents in the established diagnosis cohort completed surveys. For the entire cohort of parents, we found the mean scores on all measures of distress were within the normal ranges with 20%, 13%, and 8% of parents reporting moderate-to-severe symptoms of anxiety, depression, and PTSD, respectively. Symptoms of anxiety and depression were not significantly associated with time from diagnosis; symptoms of anxiety and PTSD were significantly associated with patients' IBD clinical activity.

Conclusions

Parents with children with IBD are remarkably resilient to distress even soon after their child's diagnosis. Despite considerable resilience, routine brief caregiver screening for symptoms of anxiety during annual visits seems reasonable and feasible.

Opt-out rates and reasons for non-participation in a single-arm feasibility trial (ENGAGE) of a guided internet-administered CBT-based intervention for parents of children treated for cancer: a nested cross-sectional survey

OBJECTIVES

Difficulties with recruitment into clinical trials are common. An opt-out recruitment strategy, whereby potential participants can decline further contact about a study (opt-out), and non-responders are contacted, may facilitate participation. Primary objectives examined opt-out and consent rates, mode and time point of opt-out, and sociodemographic characteristics of those who opted out versus those who chose to participate in a single-arm feasibility trial (ENGAGE) of a guided, internet-administered, cognitive-behavioural therapy-based intervention for parents of children treated for cancer. Secondary objectives examined reasons for non-participation.

DESIGN

A cross-sectional survey nested within the ENGAGE feasibility trial.

SETTING

The intervention was delivered from Uppsala University, with parents located throughout Sweden.

PARTICIPANTS

Potential participants were recruited 3 months-5 years following their child ending treatment for cancer and were identified via their personal identification number (via the Swedish Childhood Cancer Registry and Swedish Tax Agency) and invited via postal invitation packs and could opt out via post, online, telephone or email. Those who did not opt out or consent, within 4 weeks, received up to five telephone calls and/or one postal reminder.

RESULTS

Of 509 invited, 164 (32.2%) opted out, 78 (47.6%) via post, 53 (32.3%) via telephone, 24 (14.6%) online, and 6 (3.7%) via email, 88 (53.7%) opted out after at least one telephone call and/or postal reminder. There was a trend for parents with lower educational levels to opt out. No need of psychological support, lack of time, and no interest in internet-administered self-help were frequently reported reasons for non-participation.

CONCLUSIONS

Results emphasise the importance of using different opt-out modes and suggest future research should consider how to widen study participation for parents with lower education levels. Self-identifying a need for psychological support and the acceptability of internet-administered self-help are important factors for participation and should be considered in future research to increase recruitment.

The effect of personalised versus non-personalised study invitations on recruitment within the ENGAGE feasibility trial: an embedded randomised controlled recruitment trial

BACKGROUND

Recruitment into clinical trials is challenging and there is a lack of evidence on effective recruitment strategies. Personalisation of invitation letters is a potentially pragmatic and feasible way of increasing recruitment rates at a low-cost. However, there is a lack of evidence concerning the effect of personalising of study invitation letters on recruitment rates.

METHODS

We undertook a Study Within A Trial (SWAT) to investigate the effect of personalised versus non-personalised study invitation letters on recruitment rates into the host feasibility trial ENGAGE, a feasibility study of an internet-administered, guided, Low Intensity Cognitive-Behavioural Therapy based self-help intervention for parents of children previously treated for cancer. An intervention group (n = 254) received a personalised study invitation letter and the control group (n = 255) received a non-personalised study invitation letter. The primary outcome was the proportion of participants in the intervention group and the control group enrolled into the ENGAGE host feasibility trial. Secondary outcomes relating to the recruitment and screening process, and retention were examined. Differences in proportions between groups for the primary and secondary outcomes were estimated using logistic regression.

RESULTS

Of the 509 potential participants, 56 (11.0%) were enrolled into the ENGAGE host feasibility trial: personalised: 30/254 (11.8%) and non-personalised: 26/255 (10.2%). No statistically significant effect on personalisation of enrolment was found (OR 1.18, 95% CI 0.68-2.06). No statistically significant differences were found for any secondary outcome.

CONCLUSIONS

Personalisation of study invitations had no effect on recruitment. However, given the small study sample size in the present SWAT, and lack of similar embedded recruitment RCTs to enable a meta-analysis, additional SWATs to examine the personalisation of study invitation letters are warranted.

Conducting Digital Health Care Research: Document Analysis of Challenges Experienced During Intervention Development and Feasibility Study Setup of an Internet-Administered Intervention for Parents of Children Treated for Cancer

Background

The design and conduct of research to develop, test, and evaluate complex health care interventions is challenging. Although the existing literature describes key challenges associated with the design and conduct of definitive (evaluation) trials, there is a lack of information concerning specific challenges associated with the intervention development phase and setup of feasibility studies. In particular, the literature is scarce concerning the challenges associated with conducting digital health care research, such as research on internet-administered interventions and research using digital features to support the execution of study procedures (eg, recruitment, consent, retention, and data collection and management). This study is conducted in the context of the intervention development and feasibility study setup phases of an internet-administered, guided, low-intensity cognitive behavioral therapy–based intervention for parents of children previously treated for cancer.

Objective

The aim of this study is to explore the challenges experienced during the development phase of the internet-administered intervention and digital features to support the execution of the study procedures and a feasibility study setup.

Methods

To explore the key challenges experienced, we conducted a document analysis of written records from all study meetings held by the research team (meeting minutes) between June 7, 2018, and January 10, 2020, guided by a thematic analysis approach. Furthermore, discussion groups with members of the research team were held to develop a more detailed understanding of the key challenges experienced. Methods and results are reported in accordance with the relevant items from the Standards for Reporting Qualitative Research checklist.

Results

Six main themes were identified: decision-making and communication, expertise, external constraints, flexibility, planning and scheduling, and technical constraints.

Conclusions

Significant challenges were experienced during the intervention development and setup phases of the feasibility study. Implications are discussed to inform future design, conduct, and planning of internet-administered intervention development and feasibility studies, especially within the context of digital health care research.

Internet-Administered Cognitive Behavioral Therapy for Common Mental Health Difficulties in Parents of Children Treated for Cancer: Intervention Development and Description Study

BACKGROUND

Following the end of a child's treatment for cancer, parents may report psychological distress. However, there is a lack of evidence-based interventions that are tailored to the population, and psychological support needs are commonly unmet. An internet-administered low-intensity cognitive behavioral therapy (LICBT)-based intervention (EJDeR [internetbaserad självhjälp för föräldrar till barn som avslutat en behandling mot cancer]) may provide a solution.

OBJECTIVE

The first objective is to provide an overview of a multimethod approach that was used to inform the development of the EJDeR intervention. The second objective is to provide a detailed description of the EJDeR intervention in accordance with the Template for Intervention Description and Replication (TIDieR) checklist.

METHODS

EJDeR was developed through a multimethod approach, which included the use of existing evidence, the conceptualization of distress, participatory action research, a cross-sectional survey, and professional and public involvement. Depending on the main presenting difficulty identified during assessment, LICBT behavioral activation or worry management treatment protocols are adopted for the treatment of depression or generalized anxiety disorder when experienced individually or when comorbid. EJDeR is delivered via the Uppsala University Psychosocial Care Programme (U-CARE) portal, a web-based platform that is designed to deliver internet-administered LICBT interventions and includes secure videoconferencing. To guide parents in the use of EJDeR, weekly written messages via the portal are provided by e-therapists comprising final year psychology program students with training in cognitive behavioral therapy.

RESULTS

An overview of the development process and a description of EJDeR, which was informed by the TIDieR checklist, are presented. Adaptations that were made in response to public involvement are highlighted.

CONCLUSIONS

EJDeR represents a novel, guided, internet-administered LICBT intervention for supporting parents of children treated for cancer. Adopting the TIDieR checklist offers the potential to enhance fidelity to the intervention protocol and facilitate later implementation. The intervention is currently being tested in a feasibility study (the ENGAGE study).

Feasibility and acceptability of the "Day 100 Talk": An interdisciplinary communication intervention during the first six months of childhood cancer treatment

BACKGROUND

Communication gaps arise early in the childhood cancer trajectory and may persist. The authors conducted a pilot study of the feasibility and acceptability of a communication intervention, the Day 100 Talk (D100). D100 involves an interprofessional family conference during initial months of treatment between oncologists, psychosocial clinicians, and parents, facilitated by a 3-part conversation tool.

METHODS

The authors enrolled English-speaking parents of children with nonrelapsed, nonprogressive cancer who were receiving continuity care from enrolled pediatric oncologists and psychosocial clinicians at a single site. The a priori feasibility threshold was 60% parent completion of the D100 intervention. Surveys from parents and professionals and debrief interviews with professionals assessed D100 acceptability.

RESULTS

Thirty-seven parents (77%) and 38 oncology professionals (67%) enrolled. Twenty of 33 evaluable parents (61%) participated in a D100 family conference. Most commonly, parents did not complete the D100 intervention because of scheduling difficulties related to clinical team constraints. All 17 parents who completed a post-D100 survey agreed or strongly agreed that D100 participation was helpful. In debrief interviews, professionals identified D100 benefits, namely, stepping back to the big picture and getting on the same page, and barriers related to logistical challenges and professionals' anticipatory dread.

CONCLUSIONS

The D100 intervention pilot demonstrates high acceptability among parents of children with cancer. Despite meeting the prespecified feasibility threshold, findings highlight important barriers to D100 dissemination, namely, perceived burdens on professionals. Potential strategies to reduce burden may include using virtual visit platforms, incorporating D100 elements across multiple visits, or prioritizing intervention delivery to parents with the greatest need for enhanced communication.

Increasing Physical Activity in Empty Nest and Retired Populations Online: A Randomized Feasibility Trial Protocol

Despite the extensive evidence on the benefits of physical activity (PA) in older adults, including reduced risk of disease, mortality, falls, and cognitive and functional decline, most do not attain sufficient PA levels. Theoretical work suggests that behavioral change interventions are most effective during life transitions, and as such, a theory-based, online intervention tailored for recently retired and empty nest individuals could lend support for increasing levels of PA. The aim of this study is to examine the feasibility of the intervention and study procedures for a future controlled trial. This study has a randomized controlled trial design with an embedded qualitative and quantitative process evaluation. Participants are randomized at 1:1 between the intervention and waitlist controls. Potential participants are within six months of their final child leaving the familial home or within six months of retiring (self-defined), currently not meeting the Canadian PA guidelines, have no serious contraindications to exercise, and are residing in Victoria, British Columbia, Canada. Participants are recruited by online and print flyers as well as in-person at community events. The study aims to recruit 40 empty nest and 40 retired participants; half of each group received the intervention during the study period. The internet-delivered intervention is delivered over a 10-week period, comprising 10 modules addressing behavior change techniques associated with PA. Primary outcomes relate to recruitment, attrition, data collection, intervention delivery, and acceptability. Secondary behavioral outcomes are measured at baseline and post-treatment (10 weeks). Intervention-selected participants are invited to an optional qualitative exit interview. The results of this feasibility study will inform the planning of a randomized effectiveness trial, that will examine the behavior change, health-related fitness, and well-being outcomes by exploring how reflexive processes of habit and identity may bridge adoption and maintenance in behavioral adherence.

Study within a trial (SWAT) protocol. Investigating the effect of personalised versus non-personalised study invitations on recruitment: An embedded randomised controlled recruitment trial

Introduction

Recruitment into clinical trials is a common challenge experienced by healthcare researchers. Currently, there is little evidence regarding strategies to improve recruitment into clinical trials. However, preliminary research suggests the personalisation of study invitation letters may increase recruitment rates. As such, there is a need to investigate the effectiveness of personalisation strategies on trial recruitment rates. This study within a trial (SWAT) will investigate the effect of personalised versus non-personalised study invitation letters on recruitment rates into the host trial ENGAGE, a feasibility study of an internet-administered, guided, Cognitive-Behavioural Therapy (CBT) based self-help intervention for parents of children previously treated for cancer.

Methods

An embedded randomised controlled trial (RCT) will investigate the effectiveness of a personalised study invitation letter including the potential participant’s name and address compared with a standard, non-personalised letter without name or address, on participant recruitment rates into the ENGAGE study. The primary outcome is differences in the proportion of participants recruited, examined using logistic regression. Results will be reported as adjusted odds ratios with 95% confidence intervals.

Discussion

Even moderate effects of the personalisation of study invitation letters on recruitment rates could be of significant value by shortening study length, saving resources, and providing a faster answer to the clinical question posed by the study. This protocol can be used as a template for other researchers who wish to contribute to the evidence base for trial decision-making, by embedding a similar SWAT into their trial.

Parents' needs of support following the loss of a child to cancer: a Swedish, prospective, longitudinal, multi-centre study

Introduction: Parents' needs of support following the loss of a child to cancer and whether these needs are met are not fully known. This study aimed to describe parents' needs, opportunity, and benefit of support from healthcare professionals and significant others from shortly after, up to five years after bereavement.Material and methods: Data were collected at nine months (T5, n = 20), eighteen months (T6, n = 37), and five years after the child's death (T7, n = 38). Parents answered questions via telephone about need, opportunity, and benefit of talking to psychologists, social workers, partners, and friends. Needs were examined in relation to parent and child characteristics, including sex, age, and parent posttraumatic stress symptoms (PTSS).Results: The proportion reporting a need of support from psychologists varied from 56% and 46% at T5 to 20% and 6% at T7 (mothers and fathers, respectively). All mothers and 90% of fathers reported a need of support from social workers at T5. At T7, the corresponding percentages were 30% and 6%. More mothers than fathers reported a need of support from friends at T7 (p = .001). The proportion reporting a need of support from psychologists, social workers, and friends decreased over time (all p ≤ .050). Parents reporting a higher level of PTSS were more likely to report a need of support from social workers at T6 (p = .040) and from psychologists (p = .011) and social workers (p = .012) at T7. Opportunities for support from healthcare professionals varied, most reported need of and opportunity for support from significant others. Almost all reported benefit from received support.Conclusion: Bereaved parents need and benefit of support from healthcare professionals and significant others. Results show a need for improved access to psychosocial services, even at five years post bereavement. Large-scale studies are needed to better understand the associations between parent and child characteristics and support needs.

Attitudes and Preferences Toward a Hypothetical Trial of an Internet-Administered Psychological Intervention for Parents of Children Treated for Cancer: Web-Based Survey

BACKGROUND

Clinical trials are often challenged with issues of recruitment and retention. Little is known concerning general attitudes and preferences toward trial design and willingness to participate among parents of children treated for cancer. Furthermore, willingness to participate in internet-administered psychological interventions remains unexplored. In this study, we examined attitudes and preferences of the population regarding study procedures for a hypothetical trial of an internet-administered psychological intervention. In addition, differences in the response rate between modes of study invitation and willingness to engage in internet-administered interventions were examined.

OBJECTIVE

The primary objective of this study was to examine attitudes and preferences toward participating in an internet-administrated psychological intervention. The secondary objective was to examine the response rates and help-seeking behavior among parents of children treated for cancer.

METHODS

A cross-sectional, Web-based survey was conducted with parents of children who had completed cancer treatment. This Web-based survey examined self-reported emotional distress, prior help-seeking and receipt of psychological support, past research participation, attitudes toward research, preferences concerning recruitment procedures, and attitudes toward different types of trial design.

RESULTS

Of all the parents invited, 32.0% (112/350) completed the survey, with no difference in response rate between modes of study invitation (χ²₁=0.6, P=.45). The majority (80/112, 71.4%) of parents responded that they had experienced past emotional distress. Responses indicated high (56/112, 50.0%) or somewhat high trust in research (51/112, 45.5%), and the majority of parents would accept, or maybe accept, internet-administered psychological support if offered (83/112, 74.1%). In addition, responses showed a preference for postal study invitation letters (86/112, 76.8%), sent by a researcher (84/112, 75.0%) with additional study information provided on the Web via text (81/112, 72.3%) and video (66/112, 58.9%). Overall, parents responded that trials utilizing a waiting list control, active alternative treatment control, or a patient-preference design were acceptable.

CONCLUSIONS

Parents of children treated for cancer appear willing to participate in trials examining internet-administered psychological support. Findings of this study will inform the design of a feasibility trial examining internet-administered psychological support for the population.
