[Validation of a questionnaire for measurement of beliefs about the climacteric]

To design an instrument for measuring beliefs about the social, psychological, and physiological consequences of women's climacteric stage.

The study included 340 women affiliated to Instituto de Seguridad y Servicios Sociales para los Trabajadores del Estado (Institute for Social Services and Security for State Workers, ISSSTE) (age mean = 49.46, (SD 7.92). The mean number of pregnancies in the sample was 3.75 (SD 2.57), and the mean number of born children was 3.21 (SD 2.19); 48% of women were premenopausal, 10.9% perimenopausal, and 40.6% postmenopausal. The instrument consisted of 25 items.

A factorial analysis with Varimax rotation was carried out. Four factors were confirmed: disadvantages (alpha = 0.769), advantages (alpha = 0.839), physiological (alpha = 0.659), and psychological (alpha = 0.711).

This instrument shows good internal consistency, and measures four climacteric belief groups: a) beliefs on disadvantages, b) beliefs on advantages, c) beliefs on physiological ailments, and d) beliefs on psychological symptoms. All three confirmed dimensions of the climacteric phase have been proposed in other studies.
