Construcción y validación de una escala de autoeficacia para la actividad física

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. 2) A pilot study. 3) Determination of reliability and validity of the test. The sample was 388 adult users (18-65 years) of health centres from the province of Seville selected by cluster sampling (health centres) and quotas (town size, age and sex). Concurrent validity was found by the International Physical Activity Questionnaire (IPAQ) and discriminant validity by Beck Depression Inventory (BDI). RESULTS The results reported adequate content validity and high reliability (Cronbach Alpha > 0,9 in all factors and β = 0,96). Exploratory factor analysis showed three factors explaining 52,569% of the variance. The scale was sensitive to activity levels assessed by the IPAQ (F (1)= 4.131; p <0.05) and negatively correlated with BDI (r = -0,127; p <0,05). CONCLUSIONS The psychometric properties of the scale are appropriate for measuring the efficacy of adult users of Health Services to practice regular 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.

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). The elements that, according to Shadish, Cook, and Levinton (1991), constitute the theory of evaluation (evaluand, value, building of knowledge, and uses) have also been considered. The analysis of all these components led to the elaboration of a guideline to orient the practice of evaluation from a pragmatic perspective, in accordance with the demands and needs of a certain social context.

Construcción y validación de una escala de auto-discrepancias de competencias de cuidado en Enfermería

Objetivos: Diseñar y validar una escala para estudiantes de enfermería que identifica las concepciones en las competencias de cuidado y determina las discrepancias que puedan derivarse entre las experiencias actuales en la adquisición de competencias y los estándares o guías establecidos por la propia profesión. Métodos: Estudio transversal con una muestra de 349 estudiantes de primero y cuarto de Enfermería. Se elaboró una primera versión de la escala que fue depurada siguiendo criterios estadísticos y de jueces expertos. La escala definitiva contempla 24 ítems de competencias de cuidado. Resultados: Se aporta una escala con adecuadas propiedades psicométricas. Incluye dos subescalas con dos dominios independientes entre sí (Yo real, Yo debería). Discusión: Se plantea una línea de trabajo que introduce nuevos elementos para el análisis del bienestar y el éxito académico y profesional de los estudiantes de enfermería en función de la concepción real y normativa de las competencias de cuidado. Palabras clave: Competencia profesional. Atención de Enfermería. Autoevaluación. Estudios de Validación. Estudiantes de Enfermería.
