Impact of the "Planning to be Active" leisure time physical exercise program on rural high school students.

PURPOSE: The purpose of the study was to evaluate the effects of a Social Cognitive Theory-based intervention designed to increase the frequency of leisure time planned moderate and vigorous physical exercise among rural high school students attending physical education class. METHODS: Students in treatment and comparison groups were exposed to an activity-based physical education curricula. The treatment group received eight behavioral skill-building lessons integrated into the existing curriculum. RESULTS: The Social Cognitive Theory-based educational treatment increased levels of moderate physical exercise occurring outside the classroom. CONCLUSIONS: This study demonstrated an impact on adolescent leisure time moderate physical exercise using classroom instruction. The intervention was most effective with students who were previously sedentary. The curricular approaches used to promote regular moderate exercise may be useful for sedentary adolescents.

The long-term impact of a four-session work-site intervention on selected social cognitive theory variables linked to adult exercise adherence.

Many work-site physical activity interventions use theoretical variables in the design of their programs. Yet, these interventions do not document the degree of change in theoretical variables produced by the intervention. This study examined the construct validity of an intervention designed to affect social cognitive theory variables linked to exercise behavior. Construct validation methods were used to evaluate an instructional intervention composed of four 60-minute sessions delivered across 2 weeks. Increases were found in self-regulation skills, outcome-expectancy values, and self-efficacy for the treatment group. No significant increases were detected for the comparison group on any study variables. Sixty-seven percent of the treatment group was able to maintain exercise behavior across 12 months, whereas the comparison group declined in exercise participation from 68% to 25% across 12 months. The study revealed the intervention effective in producing the intended changes in social cognitive theory constructs. The analysis shows self-regulation-mediated exercise behavior.

A meta-analysis of adolescent psychosocial smoking prevention programs published between 1978 and 1997 in the United States.

Psychosocial smoking prevention studies have shown inconsistent results and theory-driven programs have been related to program success. This meta-analysis was used as a judgment tool for resolving these issues by estimating average program effects and investigating the relative efficacy of program types. The present study examined 65 adolescent psychosocial smoking prevention programs (1978 to 1997) among students in Grades 6 to 12 in the United States. Three program modalities (social influence, cognitive behavior, life skill) and two program settings (exclusively school based, school-community-incorporated) were identified as major a priori classifications. Knowledge had the highest effect sizes (.53) at short-term (< or = 1 year) but rapidly decreased (.19) at long-term (> 1 year). Behavioral effect was the most meaningful, being persistent over a 3-year period (.19 at < or = 1 year; .18 at 1 to 3 years). Adolescent smoking reduction rates were increased by using either cognitive behavior or life skills program modalities, and/or a school-community-incorporated program setting.

Stages of change among ethnically diverse college students.

The authors applied the stage-of-change construct in the transtheoretical model to examine the distribution of Asian (n = 869), African American (n = 373), White (n = 1322), and Hispanic (n = 535) American undergraduate students across the 5 stages of change for exercise. Stage of change varied as a function of ethnicity. Higher percentages of minorities were in the precontemplation and contemplation stages. The likelihood of being in these stages was from 43% to 82% greater for minorities than for White students. Also examined were the congruency between stage of change and self-reported levels of physical activity. Half of the sedentary students and 15.6% of the active students were misclassified by the stage-of-change procedure. Misclassification rates were higher for minority women (27.8%) than for White women (17.8%) and for Asian students (24.6%) compared with all others (20.6%). The results of this study have implications for the design of physical activity interventions based on stage of change.

Physical activity among ethnically diverse college students.

The authors compared physical activity patterns among 874 Asian, 332 African, 1,101 White, and 529 Hispanic American college students aged 18 to 25 years. According to self-report responses, 46.7% of the sample did not engage in vigorous physical activity and 16.7% were physically inactive. Among women, ethnic-specific rates of physical inactivity were Asian, 28.1%; African, 23.5%; White, 17.4%; and Hispanic, 20.3%. For men, rates of inactivity were Asian 11.7%; African, 7.7%; White, 12.0%; and Hispanic, 13.8. Weight-training activity, youthful physical activity, and TV viewing accounted for a significant portion of the variance in physical activity levels (13.1% for women and 14.8% for men). The results of this study support the need for physical activity interventions for college students, particularly minorities.

Web-assisted instruction for changing social cognitive variables related to physical activity.

The authors examined the efficacy of Web-assisted instruction for promoting the use of social cognitive theory (SCT) strategies related to physical activity. They recruited college students attending health courses. The authors created 3 groups (Web-assisted, comparison, and control) based on the course structure. The Web-assisted group received information on exercise and fitness and a Web-based program (treatment, n = 127); 7 sections received the same exercise and fitness information as the treatment condition, but no Web-based program (comparison, n = 118); and 6 sections received information in unrelated areas (control, n = 178). The Web-based program consisted of 9 Web assignments (1 per week) that targeted key SCT variables. Satisfaction with the Web-based program was high. Use of self-regulation strategies was significantly higher at posttest in the treatment group than it was in the other groups. Knowledge concerning the skills taught by the Web assignments was significantly greater in the treatment group than it was in the comparison group. The results of this study demonstrate that a Web-based instructional program has a positive impact on knowledge and skills related to SCT strategies for changing physical activity behavior.
