This study examined the psychometric properties of an adolescent version of the "triangular love scale" (TLS), which assesses three components of romantic relationships: intimacy, passion, and commitment. Using data from 435 Dutch adolescents aged 12-18 years, we found evidence for convergent validity, showing that dimensions of intimacy, passion, and commitment were all positively correlated with relationship satisfaction and duration. Evidence was also found for divergent validity, as adolescents' perceptions of the main (dis)advantages of being involved in romantic relationships showed a specific pattern of associations with intimacy, passion, and commitment. Finally, CFA analyses in LISREL showed that a model in which all separate questionnaire items were specified to load on three underlying, correlated factors (intimacy, passion, commitment) fit the data adequately. Overall, this measure seems appropriate for use with adolescents.
