Introduction: Emotion regulation difficulties have been associated with mental disorders and sexual dysfunctions.
Traditional face-to-face transdiagnostic emotion regulation interventions have shown positive results for emotional
and personality disorders. Only recently have the effects of these interventions on sexual health started to be
investigated. Internet-delivered psychological interventions have several advantages over face-to-face interventions,
such as cost-effectiveness, accessibility, and suitability for people who experience shame because of their
stigmatized problematic behaviors and those who avoid seeking help. The aims of the SHER 2—TREpS (Portuguese
acronym for Emotion Regulation training for sexual health) project are as follows: (a) determine the efficacy of an
Internet-based emotion regulation intervention for sexual health and sexual satisfaction and (b) explore the effects
of the intervention on (1) emotion regulation skills, (2) mental health, and (3) sexual self-perception.
Methods and analysis: The study will use a randomized controlled trial design. Eligible participants will be
randomly allocated to one of two groups: intervention (Internet-based emotion regulation training) or waitlist
control. Assessments will take place before the start of the trial, at the end of the trial, and at 6-month follow up,
after which participants assigned to the waitlist control condition will receive the same intervention. Primary
outcomes include sexual function and satisfaction and secondary outcomes self-report measures of depression,
anxiety, difficulties in emotion regulation, and sexual self-perception. This intervention study is financed by the
Luxembourg National Research Fund (FNS).
Ethics and dissemination: Ethics approval was obtained from the Ethics Review Panel of the University of
Luxembourg. Findings will be disseminated via peer-reviewed publications and conference presentations.
