There are limited treatment options for women with Sexual Interest/Arousal Disorder (SIAD), and most options fail to address interpersonal contexts. This study aims to examine how approach and avoidance sexual motivation influences sexual desire, sexual and relationship satisfaction, and attention to sexual cues to better understand how motivational factors could be considered in treatment. 225 self-identified women and non-binary individuals, with and without SIAD are eligible to participate. Participants will complete a manipulation involving a psycho-educational writing exercise to increase their approach or avoidance sexual motivation, or a control writing task. Participants will also complete an online attention task, where their attention to erotic and neutral videos will be assessed, to determine the impact of the sexual motivation manipulation on attention to sexual cues. The impact of the manipulation on sexual desire, sexual satisfaction, relationship satisfaction, and sexual behaviours will be assessed at 72 hours follow up.
