Purpose: To implement a culturally tailored physical activity (PA) promotion program (FunAction) and to assess its impact on five self-regulation skills and attitudes in adolescents. Design . The design and implementation of the FunAction program were informed by social marketing principles. The study used a quasi-experimental approach to assess the impact of the program on specific outcome variables.
Setting: A multiethnic, underserved middle school in Montreal, Quebec, Canada.
Subjects: The intervention group was made up of grade 8 students (n = 165) and the control group was made up of grade 7 students (n = 137).
Intervention: During the 16-week intervention, adolescents were able to choose from a variety of 45-minute cardiovascular PAs offered daily during their school lunch period. Adolescents participated in the activities on a voluntary basis.
Measures: A self-report questionnaire was administered preintervention and postintervention to measure adolescents' scores on the following self-regulation skills and attitudes: self-control, self-esteem, attention/concentration, social competence, and interethnic relationships.
Analysis: Three-way repeated measures analyses of variance and correlational analyses were used. Results . A significant improvement was observed only in attention/concentration. Girls' attention/concentration scores improved significantly in the intervention group compared to the control group (F(1,127) = 16.26, p < .001). The improvement in attention/concentration scores for boys in the intervention group was correlated with their frequency of participation in the program PAs (r = .24, p = .008).
Conclusion: Using social marketing principles can help encourage adolescents from underserved, multiethnic milieus to participate in PA during their school lunch hour. Furthermore, voluntary participation in a culturally tailored PA program can improve youths' attention/concentration.
