“…Higher mean values represent more positive instrumental and affective attitudes. Data collected using the physical activity questionnaire with adolescents provide evidence for acceptable levels of reliability [38,39]. In the present study, scores derived from this instrument displayed acceptable internal consistency at all four assessments (physical activity instrumental attitudes: Cronbach α values ≥0.81; physical activity affective attitudes: Cronbach α values ≥0.83; healthy eating instrumental attitudes: Cronbachα values ≥0.86; healthy eating affective attitudes: Cronbach's α values ≥0.84).…”

The objective of this study was to assess changes in adolescent girls' health-enhancing cognitions and behaviors targeted by the Go Girls! group-based mentorship lifestyle program. Three hundred and ten adolescent girls (nested within 40 Go Girls! groups) completed questionnaires that assessed cognitions (attitudes, self-regulatory efficacy, and intentions) and behaviors (physical activity and dietary) at four time points (two pre-program, one at the end of the program, and one at 7-week follow-up [5]. In response to these public health concerns, genderspecific lifestyle interventions have been developed for adolescent girls that target health behaviors, such as physical activity and dietary behaviors, and cognitions toward those behaviors.The majority of gender-specific lifestyle interventions for youth have tended to focus on the prevention or treatment of obesity [e.g., 6, 7]. For example, Neumark-Sztainer and colleagues [8] examined the effectiveness of a physical education program entitled "New Moves" to target health behaviors and body image among adolescent girls at risk of overweight and obesity. Results from this study [8] indicate that after completing the program, girls reported significant improvements in portion control, reductions in sedentary behavior, and increases in their physical activity self-efficacy and self-reported psychological "stage of change" for both dietary and physical activity behaviors. However, no significant changes were found for physical activity behavior or quality of dietary intake in terms of consumption of fruit and vegetables and sugar-sweetened beverages. Similarly, findings from another school-based lifestyle program for adolescent girls indicated improvements in girls' health behavior intentions and dietary knowledge, but no changes in physical activity or dietary behavior after completing the program [9].In light of the limited effectiveness of these programs, theory-based research is needed to target behavior change. Specifically, the social context has

Objective: To examine how factors related to the home food environment and individual characteristics are associated with healthy food purchasing among lowincome African American (AA) youth. Subjects: A total of 206 AA youth (ninety-one boys and 115 girls), aged 10-14 years, and their primary adult caregivers. Setting: Fourteen Baltimore recreation centres in low-income neighbourhoods. Design: Cross-sectional study. We collected information about food purchasing, the home food environment, sociodemographic and psychosocial factors drawn from social cognitive theory. Multivariable logistic regression was used to examine the factors associated with the frequency and proportion of healthy food purchases in all youth and stratified by gender. Low-fat or low-sugar foods were defined as healthy. Results: Youth purchased an average of 1?5 healthy foods (range 5 0-15) in the week before the interview, comprising an average of 11?6 % (range 5 0-80 %) of total food purchases. The most commonly purchased healthy foods included water and sunflower seeds/nuts. Healthier food-related behavioural intentions were associated with a higher frequency of healthy foods purchased (OR 5 1?4, P , 0?05), which was stronger in girls (OR 5 1?9, P , 0?01). Greater caregiver self-efficacy for healthy food purchasing/preparation was associated with increased frequency of healthy purchasing among girls (OR 5 1?3, P , 0?05). Among girls, more frequent food preparation by a family member (OR 5 6?6, P , 0?01) was associated with purchasing a higher proportion of healthy foods. No significant associations were observed for boys. Conclusions: Interventions focused on AA girls should emphasize increasing foodrelated behavioural intentions. For girls, associations between caregiver self-efficacy and home food preparation suggest the importance of the caregiver in healthy food purchasing.

It has been suggested that limitations in the measurement of subjective norms may explain this lack of predictive association (27)(28)(29) .…”

Objective: To investigate associations of self-perceived eating-related peer norms (called 'subjective peer norms') with adolescents' healthy eating intentions and intake of healthy and unhealthy food. Design: Cross-sectional data were collected in a large international survey. Setting: Two types of subjective peer norms were assessed: perceived peer encouragement of healthy eating and perceived peer discouragement of unhealthy eating. Outcome variables were healthy eating intentions, intake of healthy food (fruits and vegetables) and intake of unhealthy food (snacks and soft drinks). Subjects: Over 2500 European (pre-)adolescents aged between 10 and 17 years participated. Results: Subjective peer norms were associated with all three outcome variables. While both perceived encouragement of healthy eating and perceived discouragement of unhealthy eating were related to intentions, only peer encouragement of healthy eating was related to intakes of both healthy and unhealthy food. Conclusions: Subjective peer norms play a role in adolescent eating behaviour and as such are an important target for health promotion. Addressing norms that encourage healthy eating may be more promising in changing behaviour than norms that discourage unhealthy eating.
