In　help-　or　treatment-seeking　people,　there　may　be　a　portion　of　individuals　with　self-perceived　addiction;　however,　how　to　distinguish　these　individuals　from　help-seeking　patients　with　dysregulated　pornography　use　remains　unclear.　The　present　study　sought　to　examine　the　specific　role　of　impaired　control　in　identifying　individuals　with　self-perceived　problems　when　screening　problematic　pornography　use　(PPU)　in　a　large　help-seeking　male　sample　(N　=　8,845;　M　(age)　=　25.82　years,　SD　=　7.83).　Based　on　the　results　of　latent　profile　analysis,　three　groups　were　identified　in　the　help-seeking　sample:　Self-perceived　PPU　group　(n　=　2,089;　23.6%),　impaired　control　group　(n　=　4,180;　47.3%),　and　PPU　group　(n　=　2,576;　29.1%).　The　self-perceived　PPU　group　was　characterized　by　the　highest　moral　incongruence,　but　not　objectively　dysregulated　in　pornography　use.　The　other　two　groups　met　the　criteria　of　impaired　control,　suggesting　that,　impaired　control　may　distinguish　between　self-perceived　PPU　and　dysregulated　use　in　help-seeking　men.　Six　months　later,　self-reported　data　were　collected　again　from　972　of　these　help-seeking　men.　The　longitudinal　cross-lagged　analysis　showed　that　impaired　control　at　baseline　positively　predicted　PPU　at　the　6-month　follow-up;　simultaneously,　the　reverse　association　was　also　significant　and　positive.　In　sum,　impaired　control　functioned　as　a　criterion　to　differentiate　between　self-perceived　PPU　and　dysregulated　pornography　use.　Impaired　control　might　be　used　as　a　robust　and　reliable　predictor　of　PPU,　but　it　may　not　be　a　sufficient　criterion　of　PPU　in　itself.　Public　Health　Significance　Statement　Impaired　control　is　a　reliable　feature　when　screening　for　problematic　pornography　use　(PPU).　Impaired　control　is　a　robust　predictor　of　PPU　over　time.　Impaired　control　may　distinguish　between　individuals　with　self-perceived　PPU　and　dysregulated　PPU　in　help-seeking　samples.
