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\u2014TREpS (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.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods and analysis<\/jats:title>\n                <jats:p>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).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Ethics and dissemination<\/jats:title>\n                <jats:p>Ethics approval was obtained from the Ethics Review Panel of the University of Luxembourg.
