Description
Obesity in Hispanic youth has reached alarmingly high levels, increasing the risk of type 2 diabetes, hyperlipidemia, hypertension, and cardiovascular disease. In Mexican American children ages 6-11 years, 41.7% are overweight and obese, 24.7% are obese and 19.6% have a Body Mass Index (BMI) greater than the 97th percentile. While personal, behavioral, and environmental factors contribute to these high rates, emerging literature suggests acculturation, self-efficacy and social support are key influences. The one-group, pre- and post-test, quasi-experimental design used a community-based participatory research (CBPR) method to test the feasibility, acceptability, and preliminary efficacy of the 8-week intervention. Social Cognitive Theory (SCT) was used to guide the design. Measurements included an analysis of recruitment, retention, participant satisfaction, observation of intervention sessions, paired t-tests, effect sizes, and bivariate correlations between study variables (acculturation, nutrition and physical activity [PA] knowledge, attitude and behaviors, perceived confidence and social support) and outcome variables (BMI z-score, waist circumference and BP percentile) Findings showed the SSLN program was feasible and acceptable. Participants (n = 16) reported that the curriculum was fun and they learned about nutrition and PA. The retention rate was 94%. The preliminary effects on adolescent nutrition and PA behaviors showed mixed results with small-to-medium effect sizes for nutrition knowledge and attitude, PA and sedentary behavior. Correlation analysis among acculturation and study variables was not significant. Positive associations were found between perceived confidence in eating and nutrition attitude (r = .61, p < .05) and nutrition behavior (r = .62, p < .05), perceived confidence in exercise and nutrition behavior (r = .66, p < .05), social support from family for exercise and PA behavior (r = .67, p < .01) and social support from friends for exercise and PA behavior (r = .56, p < .05). These findings suggest a culturally specific healthy eating and activity program for adolescents was feasible and acceptable and warrants further investigation, since it may fill a gap in existing obesity programs designed for Hispanic youth. The positive correlations suggest further testing of the theoretical model.

Description
Type 1 diabetes (T1D) is one of the most common chronic diseases in youth and it has been shown that adolescents have the worst glycemic control of any age group. The objective of this study was to develop, test and evaluate the feasibility of an online intervention (Can-Do-Tude) that uses the principles of motivational interviewing (MI) to deliver tailored diabetes self-management education to adolescents with T1D. Bandura’s efficacy belief system was used to guide the design of this study.
The study used a multi-phase, multi-method approach. The first phase (alpha) of this study was a qualitative descriptive design to examine the intervention’s fidelity. Evaluation of performance was conducted by experts in the fields of MI, T1D, adolescence and/or online education. The second phase (beta) was a quantitative descriptive design conducted in order to evaluate feasibility by examining the acceptability (recruitment, retention and satisfaction) and implementation (diabetes self-management self-efficacy) to determine whether the intervention was appropriate for further testing.
First phase findings showed that the intervention passed all measures with the content experts (n = 6): it was functional, accurate, usable and secure. Improvements to the intervention were made based on reviewer recommendations. For the second phase 5 adolescents between 14 and 17 were enrolled. Three adolescents completed all 4 weeks of the intervention while 2 completed only 3 weeks. Participants (n = 3) rated satisfaction on a 5-point Likert-type scale ranging from “not at all” satisfied (1) to “very much” satisfied (5). There was a positive response to the intervention (M = 4.28, SD = 0.55). Implementation was measured by a pre- and post-test for diabetes self-management self-efficacy. Participants (n = 3) demonstrated overall improvements in diabetes self-management self-efficacy (Z = -2.952, p = .007).
Implications for further Can-Do-Tude research are planned at a metropolitan diabetes center using updated technology including an application platform. Although the sample was small, findings indicate that the intervention can be conducted using a web-based format and there is initial evidence of improvement in self-efficacy for diabetes self-management.
