Despite evidence of extensive sexual problems among alcoholics, sexual adjustment is an area of alcoholics' behavior that often has been neglected in both treatment and research. To facilitate work on alcoholics' sexual adjustment, we needed a self-report questionnaire on sexual behavior that we could use in our couples treatment program with alcoholics and in our longitudinal research on the course of alcoholics' sexual problems over time. Pilot work found that available sexual adjustment measures were either too long or too sexually explicit to be useful. This paper describes the 38-item Sexual Adjustment Questionnaire we developed by combining selected items from two existing measures. Factor analysis reduced the questionnaire to the 15 measures of sexual satisfaction and sexual dysfunction described herein. Preliminary normative data and evidence of construct validity, potential clinical and research uses of the questionnaire, and suggestions for future studies are described.
