Abstract
The aim of current article was the adaptation and validation of the Adolescents' Perceived Collective Family Efficacy Scale (EFCP/A) in the Spanish context. The sample includes 486 adolescents. Psychometric properties of the EFCP/A were examined with exploratory factor analysis, item analysis and reliability. Construct validity was examined by means of correlations with parental relationships (PBI). The correlations with drug use (tobacco, alcohol, cannabis) and coping strategies were also examined. Results supported the unidimensionality and reliability of the EFCP/A scale in the Spanish context. As hypothesised, adolescents' beliefs in collective family efficacy are highly correlated with the quality of their paternal and maternal relationships. Further, the adolescents who are convinced that their family is efficacious display more productive coping strategies and less drug use.
