Marriage and family therapists and sexual health therapists are likely to receive training in graduate school that prepares them to encounter sexual concerns among clients, but there are few standard ways to assess the efficacy of this training. The Sexual Health Education for Professionals Scale (SHEPS) was developed to address this deficit. In this preliminary study, 163 marriage and family therapy graduate students completed the SHEPS prior to starting a graduate course in assessing and treating sexual concerns. Exploratory factor analyses indicate that the SHEPS subscales have good psychometric properties. The Skills and Knowledge subscales have factors labeled Typical Clients, Special Clients, Conservative Clients, and Ethically Complicated Clients. The Attitudes subscale had factors called General Sexual Attitudes, Valuing Sexual Health Training, Open to Providing Sexual Help, and Conservatism. This new instrument may be used to assess education and training of sexual health and marriage and family therapists. Larger sample sizes and longitudinal studies are needed in future.
