Ó Beaglaoich and associates (2013, 2015a, 2015b) report that the Gender Role Conflict Scale for Adolescents (GRCS-A, Blazina et al. 2005) may not be suitable for use with Irish boys. Therefore, the purpose of the current study was to develop a culturally appropriate measure of gender role conflict (GRC). The resultant 26-item scale was entitled the Gender Role Conflict Scale for Irish Adolescents (GRCS-IA). It had satisfactory scale score reliability and a unidimensional factor structure. Evidence of convergent validity was adduced through statistically significant correlations between participants’ gender role conflict and indices of psychological functioning (i.e., self-esteem and state as well as trait anxiety). The divergent validity of the GRCS-IA also was demonstrated (i.e., participants’ gender role conflict did not correlate significantly with their endorsement of masculine norms). Limitations of the current study are outlined and directions for future research are discussed.
