Background and Objectives Although poor diet is a major driver of morbidity and mortality in people 60 and older, few dietary interventions are widely implemented for this population. We mapped behavior change theories, agents, and techniques in dietary interventions for adults 60+ and explored relationships between these factors and ability to retain at least 80% of the study participants. Research Design and Methods We conducted a scoping review using MEDLINE, CINAHL, and Web of Science through April 2021 for dietary interventions in adults 60 and older. We collated, summarized, and calculated frequency distributions of behavior change theories, behavior change agents, and behavior change techniques (BCTs) using BCTv1 taxonomy with regard to participant retention across 43 studies. Results Only 49% and 30% of the studies reported behavior theory and change agents respectively. Of the studies reporting on theory and agents, the most common were social cognitive theory and the related mechanism of self-efficacy. The most common BCTv1 were “shaping knowledge” and “goals and planning.” Several BCTv1 such as “antecedents” and “reward and threat” and evidence for concordance between BCTs and change agents were more common in interventions with higher retention rates. Discussion and Implications Mechanistically concordant studies with BCTs that involve resource allocation and positive reinforcement through rewards may be advantageous for retention in dietary intervention for older adults. Future studies should continue developing theory and mechanism-oriented research. Furthermore, future studies should consider diversifying the portfolio of currently deployed BCTs and strengthening a concordance between BCTs and mechanisms of change.

Background Web-based interventions aimed at supporting informal caregivers of people living with dementia have the potential to improve caregivers’ well-being and psychological health. However, few interventions are widely implemented for this population, and none of the prior reviews have systematically examined the use of behavior change techniques (BCTs), theories, and agents in web-based interventions for informal caregivers of people living with dementia. To better understand this implementation gap, we reviewed the literature to map behavioral factors (BCTs, theories, and agents) deployed in the studies. Furthermore, because there is an emerging consensus that retention could be shaped by participant characteristics and behavioral factors, we explored relationships between these features and retention rates across studies. Objective We pursued 3 objectives: to map behavioral factors involved in the web-based interventions for informal caregivers of people living with dementia; to examine the relationship between behavioral change elements and retention in the studies; and to examine the relationship between participant characteristics (gender, age, and spouse or adult children caregiver proportion) and study retention. Methods We conducted a literature review using the following keywords and their corresponding Medical Subject Headings terms: dementia, caregivers, and web-based intervention. The time limits were January 1998 to March 2022. Using the BCTv1 taxonomy, which specifies active behavioral components in interventions, 2 coders collected, summarized, and analyzed the frequency distributions of BCTs. Similarly, they abstracted and analyzed participant characteristics, behavior change theories, behavior change agents, and retention rates in the studies. Results The average age was 61.5 (SD 7.4) years, and the average proportion of spousal informal caregivers, adult children informal caregivers, and retention rates were 51.2% (SD 24.8%), 44.8% (SD 22%), and 70.4% (SD 17%), respectively. Only 53% (17/32) of the studies used behavior change theories, but 81% (26/32) included behavior change agents. The most common BCTv1 clusters were shaping knowledge and social support. The median number of BCTv1 clusters was 5 (IQR 3). We observed a negative correlation between the proportion of spousal informal caregivers and the retention rate (r=−0.45; P=.02) and between the number of BCTv1 clusters and retention rates (r=−0.47; P=.01). We also found that the proportion of adult children informal caregivers in the study was significantly and positively correlated with the retention rate (r=0.5; P=.03). No other participant characteristics or behavioral factors were associated with retention rates. Conclusions We found that almost half of the studies were not informed by behavior change theories. In addition, spousal involvement and a higher number of BCTs were each associated with lower retention rates, while the involvement of adult children caregivers in the study was associated with higher retention. In planning future studies, researchers should consider matching participant characteristics with their intended intervention as the alignment might improve their retention rates.

Purpose (1) To test the short-term impact of Helping Us Heal ( HUSH ), a telephone-delivered counseling program for spouse caregivers of women with breast cancer. (2) To compare outcomes from HUSH with outcomes from a historical control group which received the same program in-person. Methods Two-group quasi-experimental design using both within- and between-group analyses with 78 study participants, 26 in the within-group and 52 in the between-group analyses. Spouse caregivers were eligible if the wife was diagnosed within 8 months with stage 0–III breast cancer and were English-speaking. After obtaining signed informed consent and baseline data, 5 fully scripted telephone intervention sessions were delivered at 2-week intervals by patient educators. Spouses and diagnosed wives were assessed on standardized measures of adjustment at baseline and immediately after the final intervention session. Results Within-group analyses revealed that spouses and wives in HUSH significantly improved on depressed mood and anxiety; spouses improved on self-efficacy and their skills in supporting their wife. Additionally, wives’ appraisal of spousal support significantly improved. Between-group analyses revealed that outcomes from HUSH were comparable or larger in magnitude to outcomes achieved by the in-person delivered program. Conclusions A manualized telephone-delivered intervention given directly to spouse caregivers can potentially improve adjustment in both spouses and diagnosed wives but study outcomes must be interpreted with caution. Given the small samples in the pilot studies and the absence of randomization, further testing is needed with a more rigorous experimental design with a larger study sample.

Background and Objectives In the context of global aging, there is a need to better understand how older adults adapt to their changing health status. Engaging with Aging (EWA) is an emerging framework proposed by Carnevali which provides a new lens to understand an active, conscious daily living process of managing age-related changes (ARCs) taken on by older adults. Study aims were to 1) describe the ARCs experienced by community-dwelling older adults; and 2) identify the strategies and resources used by older adults to accommodate the daily living challenges caused by the associated ARCs. Research Design and Methods We conducted semi-structured interviews using a virtual card sort to gather qualitative data about ARCs and strategies to manage ARCs. Interviews were conducted virtually due to COVID-19 restrictions. Results Participants included 19 females and 10 males. The mean age was 77.45 years old (range from 64 to 98). Sixteen ARCs (e.g., changes in hearing, changes in stability, changes in sleep, etc.) were mentioned by participants, and their corresponding adaptations were discussed. Participants linked their adaptations to their ARCs based on their changing capacities and needs. Examples of commonly used adaptations included, for example, conserving energy, utilizing tools or technology, and being more conscious before and while taking actions. The challenges caused by COVID-19 in implementing the adaptations were also discussed. Discussion and Implications Findings from this study demonstrate how older adults explore, generate, and utilize adaptive behaviors to address their ARCS. This study substantiates the EWA framework by showing common patterns among older adults in linking ARCs with adaptations. Implications for clinicians include using EWA to help older adults identify personalized health solutions that fit their capacities. Researchers may use EWA to design and test interventions by considering the specific ARCs older adults encounter and the attitudes they hold towards the ARCs.
