Several　scales　assessing　problematic　pornography　use　(PPU)　are　available.　However,　in　most　previous　studies,　primarily　nonclinical　and　Western　samples　were　used　to　validate　these　scales.　Thus,　further　research　is　needed　to　validate　scales　to　assess　problematic　pornography　use　across　diverse　samples,　including　subclinical　populations.　The　aim　of　the　present　study　was　to　examine　and　compare　the　psychometric　properties　of　the　PPCS-18　in　Hungarian　and　Chinese　community　samples　and　in　subclinical　men.　A　sample　of　Chinese　community　men　(N1　=　695),　a　sample　of　subclinical　men　who　were　screened　for　PPU　using　the　Brief　Pornography　Screen　(N2　=　4651),　and　a　sample　of　Hungarian　community　men　(N3　=　9395)　were　recruited　to　investigate　the　reliability　and　validity　of　the　PPCS-18.　Item-total　score　correlation,　confirmatory　factor　analyses,　reliability,　and　measurement　invariance　tests　showed　that　the　PPCS-18　yielded　strong　psychometric　properties　among　Hungarian　and　Chinese　community　men　and　indicated　potential　utility　in　the　subclinical　men.　The　network　analytic　approach　also　corroborates　that　the　six　factors　of　the　PPCS-18　can　reflect　the　characteristic　of　the　participants　from　different　cultural　contexts,　and　participants　from　community　and　subclinical　populations.　In　sum,　the　PPCS-18　demonstrated　high　generalizability　across　cultures　and　community　and　subclinical　men.
