Psicothema was founded in Asturias (northern Spain) in 1989, and is published jointly by the Psychology Faculty of the University of Oviedo and the Psychological Association of the Principality of Asturias (Colegio Oficial de Psicología del Principado de Asturias).
We currently publish four issues per year, which accounts for some 100 articles annually. We admit work from both the basic and applied research fields, and from all areas of Psychology, all manuscripts being anonymously reviewed prior to publication.

Background: The aim of this study is to explore the psychometric properties of the Motiva.Diaf questionnaire, which assesses the adherence to healthy diet and physical activity in clinical patients. Method: Participants were 230 patients, who attended hospital services, with a mean age of 49.28 years (SD = 12.34). Women constituted 55.7% of the patients. Two weeks after initial administration, 40 participants, from those who had another hospital appointment scheduled, were selected at random to complete again the questionnaire in order to assess test–retest reliability. Results: the accuracy of the scores is adequate both in terms of internal consistency (α = .802; Ω = .776) and temporal stability (r =.786). The test’s structure is essentially one-dimensional, and the scores in this dimension converge with other necessary basic psychological measurements (r Diet = .294; r Physical Activity= .359) and perceived health (r = .266). In addition, a relatively moderate relationship was found with the Body Mass Index (r = - .129). Conclusions: The test has shown adequate reliability and validity for evaluating adherence to healthy habits. The availability of an instrument with these characteristics has significant implications for evaluating behaviour, designing and implementing behavioural interventions.
Adherencia a la dieta saludable y a la realización de actividad física en pacientes. Antecedentes: el objetivo de este estudio ha sido explorar las propiedades psicométricas del cuestionario Motiva.Diaf, diseñado para medir la adherencia a las características de la dieta saludable y realización de actividad física en personas enfermas. Método: participaron 230 pacientes, que asistieron a consultas hospitalarias, con una edad media de 49,28 años (SD = 12,34), siendo un 55,7 % mujeres. Dos semanas tras la administración inicial, se seleccionaron al azar 40 participantes, de los que tenían otra cita hospitalaria, para completar nuevamente el cuestionario con el fin de evaluar la fiabilidad test-retest. Resultados: la precisión de las puntuaciones es adecuada en términos de consistencia interna (α = .802; Ω = .776) y de estabilidad temporal (r =.786). La estructura del test es esencialmente unidimensional y las puntuaciones en esta dimensión convergen con las medidas de necesidades psicológicas básicas (r Diet = .294; r Physical Activity= .359) y salud percibida (r = .266). También se encontró una relación moderada con IMC (r = - .129). Conclusiones: Motiva.Diaf ha demostrado una fiabilidad y validez. La disponibilidad de un instrumento de estas características tiene implicaciones significativas en la evaluación de las conductas, diseño e implementación de intervenciones conductuales.
