Propiedades psicométricas de la versiòn castellana del cuestionario de evaluaciòn de patròn estacional (Seasonal Pattern Assessment Questionnaire, SPAQ)

The Seasonal Pattern Assessment Questionnaire (SPAQ– Rosenthal, Bradt & Wehr, 1984) is the most frequently used self-evaluation instrument for identifying the subject’s sensibility to seasonal changes. The objective of this study is to present the psychometric properties of the Spanish version of the SPAQ in young subjects. The questionnaire was administered to 592 university students (395 women and 197 men). Good psychometric properties of the SPAQ reported by authors from several countries are replicated (descriptive statistics, internal consistency, inter-item correlation and factor analysis). On the grounds of the patterns of the results we believe that the Spanish version of the SPAQ is a valuable instrument in order to further study the chronobiological aspects of psychopathologies, which are highly useful in epidemiological research and, with the due precautions, also in the clinical environment.
