Abstract:
Sexual disinhibition in dementia is correlated with multiple negative care recipient and caregiver outcomes but remains largely overlooked in the literature. Its prevalence is not well understood, with studies reporting between 1.8% and 25% presence of sexual disinhibition in dementia samples. One reason for the variability in the reported presence of sexual disinhibition may be lack of standardized methods for assessment. Several widely used measures for neuropsychiatric symptoms do not include items to assess sexual disinhibition. When measures do include sexual disinhibition, it is not addressed in a consistent manner. Inconsistency in how questions about sexual disinhibition are phrased is problematic, given that recent work shows it can differentially influence endorsement. Working toward a gold standard of sexual disinhibition measurement in dementia is needed. To this end, a systematic review of the literature to identify potentially appropriate instruments for measurement of sexual disinhibition in this population was conducted through the Web of Science and PubMed databases between January 2019 and February 2019. An overview of the 20 measures identified in this search is provided. Each measure is evaluated for appropriateness of use in dementia samples through broad examination of psychometric properties, structure, and format and the extent to which measure content overlaps with current conceptualizations of sexual disinhibition in dementia. Five common content domains were identified: hypersexuality, lewd/aberrant sexual behavior, inappropriate sexual advances, inappropriate sexual comments, and socially disruptive sexual behavior. No single measure addressed all content domains. Directions for future research are identified and discussed.
