Objective　The　purpose　of　this　study　was　to　investigate　the　different　categories　of　males　within　two　groups,　namely　a　community　male　sample　who　engaged　in　online　sexual　activities　(OSAs)　and　a　subclinical　male　sample　who　were　out　of　control　in　viewing　pornography　and　had　sought　help.　Additionally,　the　study　aimed　to　determine　the　threshold　for　excessive　OSAs　in　both　samples.　Methods　A　total　of　568　community　adult　males　who　engaged　in　OSAs　and　567　adult　males　seeking　help　for　pornography　use　were　recruited　online.　A　latent　profile　analysis　(LPA)　was　used　to　identify　potential　profiles　within　the　samples.　Cut-point　analyses　were　conducted　to　determine　optimal　cutoff　scores　for　OSAs　in　each　sample.　Results　The　LPA　revealed　two　categories　with　different　cutoff　scores　for　OSAs　within　each　sample.　Excessive　OSA　can　be　a　screening　tool　for　detecting　out-of-control　behavior.　More　stringent　criteria　for　identifying　excessive　OSAs　can　aid　in　distinguishing　problematic　pornography　use　(PPU)　from　impaired　control　in　viewing　sexually-explicit　materials　(SEMs).　Two　subcategories　of　loss　of　control　emerged:　high　OSAs　frequency　impaired　control　and　high　viewing　SEMs　impaired　control.　Conclusion　The　threholds　of　excessive　OSAs　varies　among　community　and　sub-clinical　male　samples;　this　knowledge　can　assist　in　screening　out　individuals　with　impaired　control　and　selecting　individuals　with　PPU　from　the　subclinical　sample.　Psychiatry　Investig　2024;21(12):1338-1348.　©　2024　Korean　Neuropsychiatric　Association.
