This study is a psychometric evaluation of the Sexual Activity Questionnaire, a 20-item tool that is focused on the relational, emotional, and behavioral aspects of sexual activity in the general population. The Italian Federation of Scientific Sexology proposed this tool. The study sample comprises 618 subjects (ages 18-80) from several cities in Italy. The instrument's dimensionality assessment is based on parallel analysis and exploratory factor analysis, and the evaluation of items' fit and differential functioning (with respect to the respondents' gender, age, and education) are based on the partial credit model. The statistical analyses reveal the presence of two latent variables, as measured using the Satisfaction and Complicity and Non-Penile-Vaginal Practices subscales. The items have satisfactory fit, and the two subscales' scores have good reliability. The Satisfaction and Complicity subscale is correlated with age and personal well-being but not with gender, relationship length, or the tendency to give socially desirable responses. The Non-Penile-Vaginal Practices subscale is correlated with gender and social desirability. The Sexual Activity Questionnaire shows good psychometric properties and is well-suited for use in clinical and research settings. This study includes discussions of its clinical characteristics, hypothetical applications, and future directions

Abstract
This study is a psychometric evaluation of the Sexual Activity Questionnaire, a 20-item tool that is focused on the relational, emotional, and behavioral aspects of sexual activity in the general population. The Italian Federation of Scientific Sexology proposed this tool. The study sample comprises 618 subjects (ages 18-80) from several cities in Italy. The instrument's dimensionality assessment is based on parallel analysis and exploratory factor analysis, and the evaluation of items' fit and differential functioning (with respect to the respondents' gender, age, and education) are based on the partial credit model. The statistical analyses reveal the presence of two latent variables, as measured using the Satisfaction and Complicity and Non-Penile-Vaginal Practices subscales. The items have satisfactory fit, and the two subscales' scores have good reliability. The Satisfaction and Complicity subscale is correlated with age and personal well-being but not with gender, relationship length, or the tendency to give socially desirable responses. The Non-Penile-Vaginal Practices subscale is correlated with gender and social desirability. The Sexual Activity Questionnaire shows good psychometric properties and is well-suited for use in clinical and research settings.
