The aim of the present article is to present a new instrument, specially developed to assess beliefs about sexuality that are supposed to be closely related with the development of sexual disorders. Using a cognitive theory perspective we hypothesized that sexual behaviour and its problems are in someway related to the way we think about sexuality, our beliefs and our expectations. Although some questionnaires of sexual attitude, information and beliefs already exist, there is, until now, no specific measure oriented to assess both male and female sexual dysfunctional beliefs related to aetiology. The Sexual Dysfunctional Beliefs Questionnaire is a 40-item self-reported measure constituted by two versions (female and male) rated on a five point likert scale. Both male and female versions present satisfactory test-retest reliability (r=0.73 and r=0.80 respectively), and internal consistency (Cronbach's alpha=0.93 for male and 0.81 for the female version). Studies of convergent validity show a relationship with other measures of sexual and more general beliefs, as well as with measures of sexual functioning. Discriminant validity studies support its capacity to discriminate functional from sexual dysfunctional subjects. It is expected that these measures could be useful in both clinical practice and educational programmes serving as an indicator of vulnerability to sexual dysfunction.
