摘要：The efficacy of a youth development intervention on
improving eating and physical activity(PA) self-efficacy, goal
attainment scaling, goal effort, and behaviors was examined in a
repeated measures, quasi-experimental field trial. Ethnically diverse
students (n=64) from a low-income middle school participated in the
10-session intervention driven by the Social Cognitive Theory with a
Goal Setting Theory emphasis. Participants, 13-14 years old, made
significant changes in dietary behaviors (P=0.03) and PA selfefficacy (P=0.02) after receiving the intervention. Self-efficacy did
not mediate dietary behavior change but did mediate the small
changes made in PA. Goal effort was not a mediator of behavior
change. After the intervention, more participants rated themselves
as making one lasting improvement in eating (P<0.001) and PA
(P<0.05) choices and/or were planning on making more. This study
adds to a small body of research with youth supporting use of goal
setting interventions for diet and PA change in low-income
communities.
