Effectiveness of a HealthMessages Peer-to-Peer Program for People With Intellectual and Developmental Disabilities

Lifestyle modification interventions for adults with intellectual disabilities: systematic review and meta-analysis at intervention and component levels

BACKGROUND

Adults with intellectual disabilities (IDs) are susceptible to multiple health risk behaviours such as alcohol consumption, smoking, low physical activity, sedentary behaviour and poor diet. Lifestyle modification interventions can prevent or reduce negative health consequences caused by these behaviours. We aim to determine the effectiveness of lifestyle modification interventions and their components in targeting health risk behaviours in adults with IDs.

METHODS

A systematic review and meta-analysis were conducted. Electronic databases, clinical trial registries, grey literature and citations of systematic reviews and included studies were searched in January 2021 (updated February 2022). Randomised controlled trials and non-randomised controlled trials targeting alcohol consumption, smoking, low physical activity, sedentary behaviours and poor diet in adults (aged ≥ 18 years) with ID were included. Meta-analysis was conducted at the intervention level (pairwise and network meta-analysis) and the component-level (component network meta-analysis). Studies were coded using Michie's 19-item theory coding scheme and 94-item behaviour change taxonomies. Risk of bias was assessed using the Cochrane Risk of Bias (ROB) Version 2 and Risk of Bias in Non-randomised Studies of Interventions (ROBINS-I). The study involved a patient and public involvement (PPI) group, including people with lived experience, who contributed extensively by shaping the methodology, providing valuable insights in interpreting results and organising of dissemination events.

RESULTS

Our literature search identified 12 180 articles, of which 80 studies with 4805 participants were included in the review. The complexity of lifestyle modification intervention was dismantled by identifying six core components that influenced outcomes. Interventions targeting single or multiple health risk behaviours could have a single or combination of multiple core-components. Interventions (2 RCTS; 4 non-RCTs; 228 participants) targeting alcohol consumption and smoking behaviour were effective but based on limited evidence. Similarly, interventions targeting low physical activity only (16 RCTs; 17 non-RCTs; 1413 participants) or multiple behaviours (low physical activity only, sedentary behaviours and poor diet) (17 RCTs; 24 non-RCTs; 3164 participants) yielded mixed effectiveness in outcomes. Most interventions targeting low physical activity only or multiple behaviours generated positive effects on various outcomes while some interventions led to no change or worsened outcomes, which could be attributed to the presence of a single core-component or a combination of similar core components in interventions. The intervention-level meta-analysis for weight management outcomes showed that none of the interventions were associated with a statistically significant change in outcomes when compared with treatment-as-usual and each other. Interventions with core-components combination of energy deficit diet, aerobic exercise and behaviour change techniques showed the highest weight loss [mean difference (MD) = -3.61, 95% credible interval (CrI) -9.68 to 1.95] and those with core-components combination dietary advice and aerobic exercise showed a weight gain (MD 0.94, 95% CrI -3.93 to 4.91). Similar findings were found with the component network meta-analysis for which additional components were identified. Most studies had a high and moderate risk of bias. Various theories and behaviour change techniques were used in intervention development and adaptation.

CONCLUSION

Our systematic review is the first to comprehensively explore lifestyle modification interventions targeting a range of single and multiple health risk behaviours in adults with ID, co-produced with people with lived experience. It has practical implications for future research as it highlights the importance of mixed-methods research in understanding lifestyle modification interventions and the need for population-specific improvements in the field (e.g., tailored interventions, development of evaluation instruments or tools, use of rigorous research methodologies and comprehensive reporting frameworks). Wide dissemination of related knowledge and the involvement of PPI groups, including people with lived experience, will help future researchers design interventions that consider the unique needs, desires and abilities of people with ID.

Supporting active engagement of adults with intellectual disabilities in lifestyle modification interventions: a realist evidence synthesis of what works, for whom, in what context and why

BACKGROUND

Lifestyle modification interventions for adults with intellectual disabilities have had, to date, mixed effectiveness. This study aimed to understand how lifestyle modification interventions for adults with intellectual disabilities work, for whom they work and in what circumstances.

METHODS

A realist evidence synthesis was conducted that incorporated input from adults with intellectual disabilities and expert researchers. Following the development of an initial programme theory based on key literature and input from people with lived experience and academics working in this field, five major databases (MEDLINE, EMBASE, CINAHL, PsycINFO and ASSIA) and clinical trial repositories were systematically searched. Data from 79 studies were synthesised to develop context, mechanism and outcome configurations (CMOCs).

RESULTS

The contexts and mechanisms identified related to the ability of adults with intellectual disabilities to actively take part in the intervention, which in turn contributes to what works, for whom and in what circumstances. The included CMOCs related to support involvement, negotiating the balance between autonomy and behaviour change, fostering social connectedness and fun, accessibility and suitability of intervention strategies and delivery and broader behavioural pathways to lifestyle change. It is also essential to work with people with lived experiences when developing and evaluating interventions.

CONCLUSIONS

Future lifestyle interventions research should be participatory in nature, and accessible data collection methods should also be explored as a way of including people with severe and profound intellectual disabilities in research. More emphasis should be given to the broader benefits of lifestyle change, such as opportunities for social interaction and connectedness.

The delivery of healthy lifestyle interventions for people with disability living in supported accommodation: a scoping review of intervention efficacy and consumer involvement

BACKGROUND

People with disability living in supported accommodation experience health disparities that may be partly attributed to sedentary lifestyle behaviors and poor dietary quality. Healthy lifestyle interventions have been suggested as a method of health promotion for this population; however, a synthesis of their efficacy has not yet been conducted.

OBJECTIVE

The primary aims were to (1) identify healthy lifestyle interventions delivered to people with disability living in supported accommodation and (2) examine their efficacy in supporting health and well-being. A secondary aim was to explore whether people with disability have been involved in the codesign of these interventions.

METHODS

A scoping review was conducted following the Joanna Briggs Institute's guidance for conducting scoping reviews, and six databases were searched from January 2011 to November 2021.

RESULTS

Thirty-two studies were included. Identified intervention types included training and education, exercise programs, and multicomponent interventions. A broad range of outcomes were examined; however, findings regarding efficacy were overall mixed and limited due to significant heterogeneity and the underreporting of consistently measured outcomes. The codesign of interventions in consultation with people with disability was underexplored.

CONCLUSIONS

Health promotion training for staff and tailored education for people with disability hold promise in creating a care environment that supports a healthy lifestyle. The paucity of interventions developed in consultation with people with disability is concerning and highlights the importance of meaningful co-design. The development of a theoretically informed intervention that is codesigned and addresses the broader social determinants that influence health behavior is recommended.

A systematic review of the health literacy of adults with lifelong communication disability: Looking beyond accessing and understanding information

OBJECTIVE

To determine the a) extent to which people with lifelong communication disability are included in health literacy research, b) level of health literacy of people with lifelong communication disability, c) methods applied to measure the health literacy of people with lifelong communication disability, d) barriers and facilitators mediating the health literacy of people with lifelong communication disability, and e) outcomes of health literacy interventions for people with lifelong communication disability.

METHODS

We searched for studies relating to health literacy, people with lifelong communication disability, and key areas of the Sørensen et al. (2012) health literacy model (i.e., accessing, understanding, appraising, applying health information, personal/environmental/systemic barriers and facilitators).

RESULTS

Analysis of 60 studies demonstrated that this population is not well represented. Insufficient research exists to inform statements on level of health literacy or methods used to measure health literacy of this population. Barriers and facilitators appear consistent with those applicable to the general population. Health literacy intervention outcomes were variable.

CONCLUSION

Significant gaps exist in the research which has primarily focused on people with intellectual disability accessing and understanding health information.

PRACTICE IMPLICATIONS

Findings can inform policies, practice, and future research on health literacy and people with lifelong communication disability.

A scoping review of voluntary male mentoring: Themes to connect adult men

In contemporary western cultures, such as Australia, there is increasing reported social disconnection. This disconnection is associated with loneliness and for some suicide, particularly for men. Voluntary male mentoring organisations aim to socially connect and improve men's wellbeing through facilitating men's one-to-one relationships. As is the case with most people, men value someone with whom they may communicate openly and safely, as occurs in voluntary mentoring. However, there is limited research on voluntary male mentoring or the experiences of the participants. This scoping review of the literature from voluntary adult male mentoring thematically synthesises the reported narratives from mentors. A systematic search was undertaken of five academic databases on voluntary adult male mentoring for scholarly articles in English. Additionally, the returned articles had their references reviewed for relevant authoritative reports and publications. After duplicates were removed, there were 471 publications. Sources included publications from humanities, social science, psychology and the health sciences. Once screened for eligibility this number was reduced to 29 publications. A thematic synthesis of the literature found the concepts of intentional relationship, journey and mutual growth were present. The implications of these findings are that men in community settings, informed by the experience of voluntary mentors, may be prepared to engage with other men. Additional research on the lived experience of mentors may offer further insights into facilitating male connection.

Efficacy of Healthy Aging Interventions for Adults With Intellectual and Developmental Disabilities: A Systematic Review

BACKGROUND AND OBJECTIVES

There is a lack of information on intervention strategies employed for health promotion and disease prevention for older adults with intellectual and developmental disabilities (IDDs), who usually experience poorer health compared to their peers without IDDs. We carried out the first systematic review to scrutinize the impact of intrinsic factors (e.g., cognitive, mental, and physical health) on the health status of older adults with IDDs.

RESEARCH DESIGN AND METHODS

To assess the efficacy of such interventions, we examined 23 articles including prospective "healthy aging" interventions designed for adults with IDDs. Searches were carried out in the databases Web of Science, Scielo, and PsycINFO in April 2020. Articles were organized in thematic areas: (a) physical activity and health nutrition (n = 10), (b) health education and health screening (n = 6), (c) social inclusion and community participation (n = 3), and (d) multicomponents (n = 4). Except for 5 randomized controlled trial studies, the designs were mainly nonrandomized, involving small sample sizes (Nrange = 8-379 participants), and lacking follow-up.

RESULTS

The studies included 2,398 men and women with IDDs (ranging in age from 18 to 86 years [mean age: 44.3 years]). Overall, intervention outcomes were mostly positive; however, some negative outcomes were reported.

DISCUSSION AND IMPLICATIONS

In brief, healthy aging interventions for people with IDDs remain scarce, incipient, and sporadic. We recommend that more attention needs to be given to active health promotion with people with IDDs as a program practice among organizations and as a focal public policy among governments.

Goal Setting with Latinx Families of Children with Intellectual and Developmental Disabilities: Case Studies

Behavioral community psychology focuses on studying issues that matter to communities, unpacking contextual factors that impact people's behaviors, and identifying strategies to address such issues. Goal setting is one such strategy often used by behavioral psychologists. Grounded in the values of behavioral community psychology and a behavior analysis paradigm, this study illustrated two case studies of Latinx parents of children with disabilities where goal-setting strategies were implemented to promote behavior change. The first case study focused on the promotion of healthy lifestyle behaviors and routines among Latinx families of children with disabilities in the United States. The second case study examined goal setting related to youth development by parents of adolescents with disabilities in Colombia. In both cases, participants received training on goal setting and had opportunities to discuss progress toward achieving their goals, share action steps taken, and discuss the contextual challenges or barriers that they experienced. The results indicate that behavioral goal-setting procedures can be effective in helping parents attain their goals and brainstorm strategies for addressing behavioral and contextual challenges. Implications for future research advancing behavioral community psychology are discussed.

Adolescents encouraging healthy lifestyles through a peer-led social marketing intervention: Training and key competencies learned by peer leaders

Background

Adolescents who participate as peer leaders can benefit and acquire competencies from their peer leadership experience.

Objectives

To identify the competencies gained by adolescents who participated as peer leaders in a healthy lifestyle study and to determine whether the training characteristics were related to improvement in competencies.

Design

The present study was part of the European Youth Tackling Obesity (EYTO) project, a multicentre social marketing intervention involving four European countries.

Setting and Participants

Eighteen peer leaders (aged 13–15 years, three or five leaders per country) from disadvantaged neighbourhoods received training in designing and implementing activities for their peers.

Measures

The peer leaders' confidence, experience and interest in 11 tasks related to lifelong learning competencies were assessed with questions rated on a colour scale at baseline and at the end of the study.

Results

The peer leaders demonstrated improvements in experience, confidence and interest in different tasks, such as research, website or logo design, oral presentations, social media use and collaboration with people from other countries. They increased their confidence in management tasks (p = 0.03) and their confidence and experience in communication tasks (p = 0.01). The peer leaders from Spain and Portugal had greater improvements than those from the other countries.

Conclusion

The peer leaders improved their confidence in management tasks and their confidence and experience in communication tasks. Slight differences were detected in improvement in competencies by country, likely due to the differences in the peer training applied. Recommendations for peer leader training are proposed, although these results should be verified with larger sample size.

Patient or Public Contribution

The peer leaders contributed to the design and implementation of the training and intervention.

A Systematic Review of Health Promotion Programs to Improve Nutrition for People with Intellectual Disability

PURPOSE OF REVIEW

To investigate the type and effectiveness of health promotion programs designed to improve nutrition for people with intellectual disability. This review also sought to highlight gaps in the evidence by mapping interventions to the socio-ecological model.

RECENT FINDINGS

To date, reviews on health promotion programs for people with intellectual disability have focused on individualised weight management interventions and behaviour change techniques. No reviews have focused solely on nutrition or considered a broader range of interventions and policies targeted beyond the individual. This review found that health promotion interventions to date were predominantly at the individual level of the socio-ecological model and of varying effectiveness. Of the non-individually focused interventions, those targeting the physical environment or considering multiple socio-ecological levels achieved the greatest improvements in nutrition outcomes. Nutrition and obesity prevention research and policy need to include intellectual disability as part of equity considerations, while intellectual disability policy needs to consider the broader food environment.

How can care settings for people with intellectual disabilities embed health promotion?

BACKGROUND

People with intellectual disabilities (ID) depend on their environment to live healthily. Asset-based health promotion enhances a settings' health-promoting capacity starting with identifying protective or promotive factors that sustain health.

METHOD

This inclusive mixed-methods study used group sessions to generate and rank ideas on assets supporting healthy nutrition and physical activity in Dutch intellectual disability care settings. Participants included people with moderate intellectual disabilities and family and care professionals of people with severe/profound intellectual disabilities.

RESULTS

Fifty-one participants identified 185 assets in group sessions. They include the following: (i) the social network and ways "people" can support, (ii) assets in/around "places," and person-environment fit, and (iii) "preconditions": health care, prevention, budget, and policy.

CONCLUSION

This inclusive research provides a user perspective on assets in the living environment supporting healthy living. This gives insight in contextual factors needed for development and sustainable embedment of health promotion in the systems of intellectual disability support settings.
