Background　and　aims:　Despite　its　inclusion　in　the　11th　revision　of　the　International　Classification　of　Diseases,　there　is　a　virtual　paucity　of　high-quality　scientific　evidence　about　compulsive　sexual　behavior　disorder　(CSBD),　especially　in　underrepresented　and　underserved　populations.　Therefore,　we　comprehensively　examined　CSBD　across　42　countries,　genders,　and　sexual　orientations,　and　validated　the　original　(CSBD-19)　and　short　(CSBD-7)　versions　of　the　Compulsive　Sexual　Behavior　Disorder　Scale　to　provide　standardized,　state-of-the-art　screening　tools　for　research　and　clinical　practice.　Method:　Using　data　from　the　International　Sex　Survey　(N　=　82,243;　Mage　=　32.39　years,　SD　=　12.52),　we　evaluated　the　psychometric　properties　of　the　CSBD-19　and　CSBD-7　and　compared　CSBD　across　42　countries,　three　genders,　eight　sexual　orientations,　and　individuals　with　low　vs.　high　risk　of　experiencing　CSBD.　Results:　A　total　of　4.8%　of　the　participants　were　at　high　risk　of　experiencing　CSBD.　Country-and　gender-based　differences　were　observed,　while　no　sexual-orientation-based　differences　were　present　in　CSBD　levels.　Only　14%　of　individuals　with　CSBD　have　ever　sought　treatment　for　this　disorder,　with　an　additional　33%　not　having　sought　treatment　because　of　various　reasons.　Both　versions　of　the　scale　demonstrated　excellent　validity　and　reliability.　Discussion　and　conclusions:　This　study　contributes　to　a　better　understanding　of　CSBD　in　underrepresented　and　underserved　populations　and　facilitates　its　identification　in　diverse　populations　by　providing　freely　accessible　ICD-11-based　screening　tools　in　26　languages.　The　findings　may　also　serve　as　a　crucial　building　block　to　stimulate　research　into　evidence-based,　culturally　sensitive　prevention　and　intervention　strategies　for　CSBD　that　are　currently　missing　from　the　literature.
