The　UPPS-P　Impulsive　Behavior　Model　and　the　various　psychometric　instruments　developed　and　validated　based　on　this　model　are　well　established　in　clinical　and　research　settings.　However,　evidence　regarding　the　psychometric　validity,　reliability,　and　equivalence　across　multiple　countries　of　residence,　languages,　or　gender　identities,　including　gender-diverse　individuals,　is　lacking　to　date.　Using　data　from　the　International　Sex　Survey　(N　=　82,243),　confirmatory　factor　analyses　and　measurement　invariance　analyses　were　performed　on　the　preestablished　five-factor　structure　of　the　20-item　short　version　of　the　UPPS-P　Impulsive　Behavior　Scale　to　examine　whether　(a)　psychometric　validity　and　reliability　and　(b)　psychometric　equivalence　hold　across　34　country-of-residence-related,　22　language-related,　and　three　gender-identity-related　groups.　The　results　of　the　present　study　extend　the　latter　psychometric　instrument＇s　well-established　relevance　to　26　countries,　13　languages,　and　three　gender　identities.　Most　notably,　psychometric　validity　and　reliability　were　evidenced　across　nine　novel　translations　included　in　the　present　study　(i.e.,　Croatian,　English,　German,　Hebrew,　Korean,　Macedonian,　Polish,　Portuguese-Portugal,　and　Spanish-Latin　American)　and　psychometric　equivalence　was　evidenced　across　all　three　gender　identities　included　in　the　present　study　(i.e.,　women,　men,　and　gender-diverse　individuals).
