A description of the social-ecological framework used in the trial of activity for adolescent girls (TAAG).

Social-ecological (SE) models are becoming more widely used in health behavior research. Applying SE models to the design of interventions is challenging because models must be tailor-made for each behavior and population, other theories need to be integrated into multi-level frameworks, and empirical research to guide model development is limited. The purpose of the present paper is to describe a SE framework that guided the intervention and measurement plans for a specific study. The trial of activity for adolescent girls (TAAG) is a multi-center study of interventions to reduce the decline of physical activity in adolescent girls. The TAAG framework incorporates operant learning theory, social cognitive theory, organizational change theory and the diffusion of innovation model in a multi-level model. The explicit and practical model developed for TAAG has already benefited the study and may have elements that can generalize to other health promotion studies.

Data to action: using formative research to develop intervention programs to increase physical activity in adolescent girls.

Formative research is used to inform intervention development, but the processes of transmitting results to intervention planners and incorporating information into intervention designs are not well documented. The authors describe how formative research results from the Trial of Activity for Adolescent Girls (TAAG) were transferred to planners to guide intervention development. Methods included providing oral and written reports, prioritizing recommendations, and cross-checking recommendations with intervention objectives and implementation strategies. Formative work influenced the intervention in many ways. For example, results indicated that middle schools offered only coeducational physical education and health education classes, so the TAAG intervention was designed to be appropriate for both sexes, and intervention strategies were developed to directly address girls' stated preferences (e.g., enjoyable activities, opportunity to socialize) and barriers (e.g., lack of skills, fear of injury) for physical activity. The challenges of using formative research for intervention development are discussed.

A pilot school-based healthy eating and physical activity intervention improves diet, food knowledge, and self-efficacy for native Canadian children.

The Sandy Lake school-based diabetes prevention program is a culturally appropriate intervention for Ojibway-Cree students in the 3rd, 4th, and 5th grades. This paper reports the results of the program in changing dietary intake behaviors and related psychosocial factors. Physical activity results are not included. The study was a pretest/post-test, single-sample design conducted during the 1998-1999 school year. A total of 122 students completed all 4 measurements (anthropometry, 24-h dietary recall, and 2 questionnaires), at baseline and follow-up. There were significant increases (P < 0.0001) in dietary intention, dietary preference, knowledge, and dietary self-efficacy, and in the curriculum knowledge scale between baseline and follow-up. Intervention exposure was significantly associated with being in the highest category for knowledge about foods that were low in dietary fat [Medium Exposure odds ratio (OR): 3.4; P < 0.05; High Exposure OR: 6.4; P < 0.05], being in the highest category for dietary self-efficacy (Medium Exposure OR: 3.7; P < 0.05; High Exposure OR: 3.9; P < 0.1), being in the highest category for knowledge about curriculum concepts (Medium Exposure OR: 3.4; P < 0.05; High Exposure OR: 9.4: P < 0.01), and for having met the age + 5 g dietary fiber intake/d (Medium Exposure OR: 2.9; P < 0.1; High Exposure OR: 11.0; P < 0.01). Exposure to the intervention was not associated with dietary intent or the percentage of energy from dietary fat. This program was associated with improved knowledge and the psychosocial factors related to healthy eating and dietary fiber intake of students in a remote First Nations community.
