Summary Lay health worker-led health promotion interventions are well received within racial and ethnic minority communities. Increasing numbers of trained lay health workers will be needed to meet global health goals. The purpose of this process evaluation was to gain insights about how lay health worker as interventionists used theory-based approaches within a nutrition and physical activity health behavior change intervention in a clinical trial enrolling immigrant and refugee families. Data were comprised of ongoing reflective writing statements from four health workers about their implementation of the intervention. Using content analysis three themes emerged: (i) encouraging setting of small, family focused and relevant goals, (ii) being flexible in content delivery and (iii) being personally transformed (i.e. gained a sense of meaning from their experience). Lay health worker interventionist reflections on practice revealed they delivered the intervention within the primacy of the family partnering relationship by attending to unique family needs, and adjusting educational content and goal setting accordingly. Our results provide guidance for training and process evaluation of lay health worker intervention delivery in ethnically and racially diverse populations. Incorporating real-time reflection upon what was learned about skills of facilitating family motivation and family confidence enhanced affective learning and may be useful in future research studies and health promotion practice. The processes identified including setting small goals, flexibility and personal transformation could be considered in future lay health worker-delivered health promotion interventions.
Healthy Immigrant Families: Randomized Controlled Trial of a Family-Based Nutrition and Physical Activity Intervention
Purpose: To evaluate a healthy eating and physical activity intervention for immigrant families, derived through community-based participatory research. Design: The Healthy Immigrant Families study was a randomized controlled trial with delayed intervention control group, with families as the randomization unit. Setting: US Midwest city. Participants: Participants were recruited by community partners from Hispanic, Somali, and Sudanese immigrant communities. Intervention: Family health promoters from participating communities delivered 6 healthy eating modules, 4 physical activity modules, and 2 modules synthesizing information in 12 home visits (60-90 minutes) within the first 6 months. Up to 12 follow-up phone calls to each participant occurred within the second 6 months. Measures: Primary measures were dietary quality measured with weekday 24-hour recall and reported as Healthy Eating Index score (0-100) and physical activity measured with accelerometers (14 wear days) at baseline, 6, 12, and 24 months. Results: In total, 151 persons (81 adolescents and 70 adults; 44 families) were randomly assigned. At 12 months, significant improvement occurred in Healthy Eating Index scores for adults in the intervention group compared with controls (change, +8.6 vs −4.4; P < .01) and persisted at 24 months (+7.4 from baseline; P < .01). No differences were observed for adolescents and no significant differences occurred between groups for physical activity. Conclusion: This intervention produced sustained dietary quality improvement among adults but not among adolescents. Program outcomes are relevant to communities working to decrease cardiovascular risk among immigrant populations.
Treatment Fidelity Among Family Health Promoters Delivering a Physical Activity and Nutrition Intervention to Immigrant and Refugee Families
Lack of treatment fidelity can be an important source of variation affecting the credibility and utility of outcomes from behavioral intervention research. Development and implementation of a well-designed treatment fidelity plan, especially with research involving underserved populations, requires careful conceptualization of study needs in conjunction with what is feasible in the population. The purpose of this article is to review a fidelity-monitoring plan consistent with the National Institutes of Health Behavior Change Consortium guidelines (e.g., design, training, delivery, receipt, and enactment) for an intervention trial designed to improve physical activity and nutrition among immigrant and refugee families. Description of the fidelity monitoring plan is provided and challenges related to monitoring treatment fidelity in a community-based participatory intervention for immigrant and refugee families are discussed.
Screening for Tuberculosis at an Adult Education Center: Results of a Community-Based Participatory Process
Objectives. We used a community-based participatory research (CBPR) approach to plan and implement free TB skin testing at an adult education center to determine the efficacy of CBPR with voluntary tuberculosis (TB) screening and the prevalence of TB infection among immigrant and refugee populations. Methods. We formed a CBPR partnership to address TB screening at an adult education center that serves a large immigrant and refugee population in Rochester, Minnesota. We conducted focus groups involving educators, health providers, and students of the education center, and used this input to implement TB education and TB skin testing among the center's students. Results. A total of 259 adult learners volunteered to be skin-tested in April 2009; 48 (18.5%) had positive TB skin tests. Conclusions. Our results imply that TB skin testing at adult education centers that serve large foreign-born populations may be effective. Our findings also show that a participatory process may enhance the willingness of foreign-born persons to participate in TB skin-testing efforts.
