Challenges to and strategies for recruiting chronic care dyads into intervention research

Recruitment Challenges and Strategies in a Technology-Based Intervention for Dementia Caregivers: Descriptive Study

Background

Researchers have encountered challenges in recruiting unpaid caregivers of people living with Alzheimer disease and related dementias for intervention studies. However, little is known about the reasons for nonparticipation in in-home smart health interventions in community-based settings.

Objective

This study aimed to (1) assess recruitment rates in a smart health technology intervention for caregivers of people living with Alzheimer disease and related dementias and reasons for nonparticipation among them and (2) discuss lessons learned from recruitment challenges and strategies to improve recruitment.

Methods

The smart health intervention was a 4-month, single-arm trial designed to evaluate an in-home, technology-based intervention that monitors stressful moments for caregiving dyads through acoustic signals and to provide the caregivers with real-time stress management strategies. The recruitment involved two main methods: on-site engagement by a recruiter from a memory clinic and social media advertising. Caregivers were screened for eligibility by phone between January 2021 and September 2023. The recruitment rates, reasons for nonparticipation, and participant demographics were analyzed using descriptive statistics.

Results

Of 201 caregivers contacted, 11 were enrolled in this study. Eighty-two caregivers did not return the screening call, and others did not participate due to privacy concerns (n=30), lack of interest (n=29), and burdensome study procedures (n=26). Our recruitment strategies included addressing privacy concerns, visualizing collected data through a dashboard, boosting social media presence, increasing the recruitment budget, updating advertisements, and preparing and deploying additional study devices.

Conclusions

This study highlighted barriers to participation in the smart health intervention. Despite several recruitment strategies, enrollment rates remained below expectations. These findings underscore the need for future research to explore alternative methods for increasing the recruitment of informal dementia caregivers in technology-based intervention studies.

Physical Activity Together for Multiple Sclerosis (PAT-MS): A randomized controlled feasibility trial of a dyadic behaviour change intervention

Background

Many people with advanced multiple sclerosis (MS) and their care-partners do not engage in sufficient physical activity (PA) for health benefits. We developed "Physical Activity Together for MS (PAT-MS)", a 12-week dyadic behavioural intervention, to promote PA among these dyads. Herein, we evaluated the feasibility of PAT-MS before a definitive trial.

Methods

A randomized controlled feasibility trial, with 1:1 allocation into the intervention or wait-list control condition. Predefined progression criteria included rates of recruitment, retention, safety, participant satisfaction and adherence. Changes in self-reported and accelerometer-measured PA were assessed at baseline and post-intervention using mixed-factor ANOVAs. Effects sizes were calculated as Cohen's d.

Results

The recruitment rate (i.e., 20 participants in 10 months) was not acceptable. However, retention (80%) was acceptable. No serious adverse events were reported. There were high levels of participant satisfaction with the intervention (content (median = 6 out of 7), facilitator (median = 7 out of 7), and delivery (median = 5 out of 7)) and adherence (92% of the group sessions, 83% of the individual support calls, and 80% of the practice activities were completed). There were statistically significant time-by-condition interactions on self-reported PA, steps/day, and %wear time and minutes in sedentary behaviour, and moderate-to-vigorous PA from baseline to post-intervention in people with MS and their family care-partners.

Conclusion

PAT-MS appears feasible, safe, and efficacious for PA promotion in MS dyads. We established effect size estimates to power a future definitive trial and identified necessary methodological changes to increase the efficiency of study procedures and improve the quality of the intervention.

Prerandomization withdrawals from a Type 2 diabetes self-care support intervention trial are associated with lack of available support person coparticipant

OBJECTIVES

Dyadic interventions, involving two persons with a preexisting close relationship, offer the opportunity to activate support persons (SPs) to improve health for adults with chronic conditions. Requiring SP coparticipation can challenge recruitment and bias samples; however, the associations between voluntary SP coparticipation and recruitment outcomes across patient characteristics are unknown.

METHODS

The Family/Friend Activation to Motivate Self-care 2.0 randomized controlled trial (RCT) enrolled adults with Type 2 diabetes (T2D) from an academic health system. Participants were asked-but not required-to invite an SP to coenroll. Using data from the electronic health record we sought to describe RCT enrollment in the setting of voluntary SP coparticipation.

RESULTS

In a diverse sample of adults with (T2D) (48% female, 44% minoritized race/ethnicity), most participants (91%) invited SPs and (89%) enrolled with SPs. However, prerandomization withdrawal was significantly higher among participants who did not have consenting SPs than those who did. Females were less likely to invite SPs than males and more Black PWD were prerandomization withdrawals than randomized.

DISCUSSION

Voluntary SP coenrollment may benefit recruitment for dyadic sampling; however, more research is needed to understand if these methods systematically bias sampling and to prevent these unintended biases.

Differences between complete and incomplete couples in physical health research: Implications for methods and generalizability

RATIONALE

Couples-based interventions to facilitate health behavior change and improve disease outcomes are gaining attention from researchers. Dyadic research, however, poses unique methodological challenges that have raised questions about research samples and the generalizability of findings.

OBJECTIVE

The current study examined whether couples in which both partners participated (i.e., complete couples) in a couples' health research study systematically differed from those in which only one partner participated (i.e., incomplete couples).

METHODS

Between January 2014 and November 2015, an online survey was advertised on Facebook to people who were both engaged to be married and living in the Denver, Colorado metropolitan area. When the first member of a couple completed the survey (initially recruited participant), they provided their partner's email address, which prompted the research staff to invite the second partner to complete the same online survey. Constructs assessed included demographics, health behaviors, general health status, and relationship quality. Participants answered questions about themself and their partner. Approximately one-third of the partners of initially recruited participants also participated. Data from initial participants in complete couples (N = 265) were compared to data from initial participants in incomplete couples (N = 509).

RESULTS

Chi-square tests and independent samples t-tests indicated participants in incomplete couples had significantly lower relationship quality, worse health behaviors, and poorer health status compared to those in complete couples. Reports on partner health behaviors also differed in the same direction between the two groups. Participants in complete couples were more likely to be White, less likely to have children, and had more education than in incomplete couples.

CONCLUSIONS

Findings suggest that studies requiring both members of a couple may recruit samples that are less diverse with fewer health concerns than research that only requires individual participation if their partner refused participation. Implications and recommendations for future couples-based health research are discussed.

Feasibility of a meditation intervention for stroke survivors and informal caregivers: a randomized controlled trial

BACKGROUND

Depressive symptoms are a significant psychological complication of stroke, impacting both survivors and informal caregivers of survivors. Randomized controlled trials are needed to determine optimal non-pharmacological strategies to prevent or ameliorate depressive symptoms in stroke survivors and their informal caregivers.

METHODS

A prospective, randomized, parallel-group, single-center, feasibility study. Participants were assigned to a 4-week meditation intervention or expressive writing control group. The intervention comprised four facilitator-led group meditation sessions, one session per week and building upon prior session(s). Descriptive statistics were used to examine the proportion of eligible individuals who enrolled, retention and adherence rates, and the proportion of questionnaires completed. Data were collected at baseline, immediately after the 4-week intervention period, and 4 and 8 weeks after the intervention period. Secondary analysis tested for changes in symptoms of depression (Center for Epidemiologic Studies-Depression [CES-D]), anxiety [State-Trait Anxiety Inventory for Adults (STAI)], and pain (Brief Pain Inventory-Short Form) in the intervention group via paired t tests. Linear mixed models were used to compare longitudinal changes in the measures between the groups. Intervention and trial design acceptability were preliminary explored.

RESULTS

Seventy-one (77%) individuals enrolled and 26 (37%) completed the study (baseline and 8-week post-intervention visits completed). Forty-two (66%) participants completed baseline and immediate post-intervention visits. Mean questionnaire completion rate was 95%. The median meditation group session attendance rate for the intervention group was 75.0%, and the mean attendance rate was 55%. Non-significant reductions in CES-D scores were found. Paired t tests for stroke survivors indicated a significant reduction from baseline through week 8 in BPI-sf severity scores (p = 0.0270). Repeated measures analysis with linear mixed models for informal caregivers indicated a significant reduction in in STAI-Trait scores (F [3,16.2] = 3.28, p = 0.0479) and paired t test showed a significant reduction from baseline to week 4 in STAI-Trait scores (mean = - 9.1250, 95% CI [- 16.8060 to 1.4440], p = 0.0262). No between-group differences were found.

CONCLUSIONS

Future trials will require strategies to optimize retention and adherence before definitive efficacy testing of the meditation intervention.

Use of the Self- and Family Management Framework in quantitative studies

BACKGROUND

The Self- and Family Management Framework (SFMF) identifies factors and outcomes of patient and family management of chronic illness. In a previous citation analysis, we reported the frequency and nature of use of the SFMF.

PURPOSE

We conducted a sub-analysis of quantitative articles in the citation analysis to examine testing of relationships depicted in the SFMF.

METHODS

We analyzed study purposes, independent and dependent variables, study implications, and text that referred to the SFMF in 40 articles.

FINDINGS

The SFMF has been used largely to explore factors affecting SFM behaviors, focusing on patient versus family self-management. Independent variables included all categories of facilitators/barriers specified in the SFMF. Dependent variables included all SFMF components (Facilitators/Barriers, Processes, Proximal and Distal Outcomes). Racial/ethnic diversity was limited among study participants. Study implications pertained mostly to psychosocial outcomes. Most studies referred to the SFMF generally.

DISCUSSION

Findings will contribute to revision of the SFMF.

Psychological and Sexual Distress in Rectal Cancer Patients and Partners

BACKGROUND

Rectal cancer (RC) patients experience unique sources of distress, including sexual dysfunction and body image concerns, which can also cause distress among partners. This preliminary study investigated patterns of psychological distress, sexual functioning, sexual distress, and relationship satisfaction among RC patient-partner couples at pivotal points during cancer treatment.

METHODS

Twenty couples participated (N=40). Patients and partners completed a series of validated measures of psychological distress (ET), sexual functioning (FSFI; IIEF), sexual distress (GMSEX; Sexual Distress Scale) and relationship satisfaction (GMREL) at time of diagnosis, 3 weeks after radiation, 4 weeks post-surgery, and after chemotherapy and surgery for ostomy closure. Descriptive statistics, t-tests, and repeated-measures ANOVA were used to analyze scores over time, first for patients and partners, and then by sex.

RESULTS

Relationship satisfaction remained elevated over time. In this sample, 55% of patients and 78.9% of partners reported clinically significant rates of psychological distress at diagnosis, which decreased to 23% and 46% respectively at the last assessment. Sexual satisfaction and distress worsened for patients and partners between baseline and surgery for ostomy closure. Both male and female participants reported statistically significant declines in sexual function from baseline to end of treatment (p< .05).

DISCUSSION

Relative to relationship satisfaction, psychological and sexual health outcomes seem more vulnerable to the effects of RC treatment during the first year after diagnosis, both for patients and partners and for men and women. Results support the need for psychosocial care and sexual education/counseling for couples coping with RC. This article is protected by copyright. All rights reserved.
