Development and psychometric properties of an instrument for the Assessment of Sexual Behaviour and Knowledge of people with Intellectual Disability

ABSTRACT Background This paper presents psychometric properties of an instrument for the Assessment of Sexual Behaviour and Knowledge of people with Intellectual Disability (ASBKID), other‐reported by professionals who are in daily contact with them. Methods and procedures Assessments of 236 individuals with intellectual disability were obtained from 100 professionals. Results Confirmatory factor analysis revealed a four‐factor structure: concern about the user's inappropriate or uninhibited sexual behaviour; perception of the user's knowledge about privacy and social norms; perception of the user's knowledge about sexuality; and concerns about the user's sexuality. A multi‐group CFA was also conducted in men and women, confirming the adequacy of this four‐factor structure by gender. The reliability of the factors ranged from 0.74 to 0.92. Conclusions The psychometric results obtained support the use of the ASBKID as a valid and reliable measure for the assessment of sexual behaviour and knowledge in both men and women with intellectual disability.
