Psychometric Validation of the Coparenting Relationship Scale in Portuguese Mothers

The aim of the present study was to adapt and validate the Coparenting Relationship Scale —crs— in a sample of Portuguese mothers. The original version of this measure assesses in seven  subscales the four dimensions of coparenting described in the ecological model of coparenting.  The study was composed by a sample of 548 mothers having a heterosexual intimate relationship and with at least one child (under 18 years) from the current marital relationship. Using a confirmatory factor analysis, the final factor solution revealed a satisfactory adjustment, suggesting the construct validity of the crs, χ2 (372) = 828.5, ns, cfi = 0.95, nfi = 0.91 e rmsea = 0.04 (90 % ic = 0.04-0.05). The scale also showed coefficients of internal consistency between satisfactory and elevated in all subscales (Cronbach’s α between 0.70 and 0.94) and satisfactory values of convergent and divergent validity, obtained through correlational analysis of crs with other theoretically selected constructs. The results give initial support to the psychometric quality of the Portuguese version of crs.
