[Construction and validation of a self-efficacy scale for physical activity].

Background: The estimation by standardized tests on belief in personal capacity to practice regular physical activity (self-efficacy for physical activity) allows us to make predictions about the actual practice of this behavior. We do not have measuring instruments suitable for this purpose, therefore, we propose to construct and validate a scale to determine levels of self-efficacy of adult users of the Primary Health Care Services for regular physical activity.

Methods: Phases: 1) Develop and review the scale by expert judges.

A pragmatic guideline for evaluation of social intervention.

Considering the many theoretical and methodological viewpoints in the field of evaluation, a guideline was established to facilitate the evaluation of social intervention programs. For this purpose, the goals of the evaluation were taken into account: (a) planning interventions, (b) learning and continuous improvement of interventions, (c) programming policies, and (d) transformation of society. These goals will determine the perspective of the analysis selected (focusing on the evaluand or the context) and the strategies for change employed (focusing on processes or results).
