The aim of this study was to translate and search for validity evidence of Iowa-Netherlands Comparison Orientation Scale for adolescents’ Portuguese context. This scale assesses levels of social comparison orientation. Participants were 238 adolescents, with ages between 13 and 18 years (M = 15.43, SD = 1.76). We verified that scale structure was in line with the original instrument version. Two dimensions emerged: Opinions and Abilities, both with satisfactory internal consistency indices. The dimension Opinions correlated positively with Self-esteem and Materialism; Abilities showed positive correlations with Self-compared, Materialism and Impulse buying. Regarding sex differences, girls showed higher mean for Opinions; boys higher mean for Abilities. Our results strengthen the Portuguese scale version adequacy to assess a tendency towards social comparison in adolescents.
