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 26item 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. KEYWORDS boys, gender role conflict, Ireland, masculinity, psychometrics Gender role conflict (GRC), defined as a "psychological state in which socialized gender roles have negative consequences for the person or others" (O'Neil 2015: 42), prevents individuals from realizing their full potential as human beings. Furthermore, findings from more than 350 studies suggest that GRC may compromise men's psychological and physical health (O'Neil 2015). To illustrate: GRC correlates positively with depression, stress, anxiety, shame, body dissatisfaction, alexithymia, substance use/misuse, and suicide probability, and negatively with self-esteem. The associations between GRC and both depression and self-esteem are particularly robust, having been found with samples that are diverse in terms of their cultural, racial, and sexual identity composition (O'Neil 2015).
