摘要：Abstract This study was designed with a dual goal: (1) to compare the change in the scores of depressive symptoms by means of the implementation of three intervention programs in comparison to a control group: a) based on Epstein's {TARGET} (ET), b) without {TARGET} strategies (NET), and c) under conditions of active exercise (AE); and (2) to analyze whether the Self-determination Index (SDI) predicts the reduction of depressive symptoms. The participants (N = 106; 68 females and 38 males), aged between 18-30 years, were randomly assigned to one of the groups. Each treatment lasted 8 weeks (3 hours/week). Of the {ET} participants, 59.26% showed a therapeutic response, defined as a 50% reduction in the reference score, versus 25.93% for the NET, 19.23% for the AE, and 3.84% for the control group. After six months, the {ET} group increased their percentage of therapeutic response by slightly more than 10%, which did not occur in the other groups. {SDI} predicted lower levels of depressive symptoms, and our findings indicate that {TARGET} strategies can have a direct effect on depressive symptoms at the time of intervention and an indirect effect at a later stage due to their impact on future levels of physical activity.
