Adaptación de la escala de apoyo social familiar y de amigos (AFA-R) como medida del apoyo social de pareja en mujeres mexicanas embarazadas

Abstract

Background and aimsSocial support represents a protective factor for pregnant women, contributing to the favorable coping of stressors. Hence the importance of a partner's social support, since their involvement promotes a woman's adaptation to pregnancy, affecting her physical and psychological health. The objective of the study was to adapt and evaluate the internal structure of the AFA-R scale as a measure of family and partner's social support. Material and methodsTwo hundred and eighty fourMexican pregnant women participated. Sampling for convenience was performed in health sector clinics. Internal consistency analysis, exploratory factor analysis (EFA) (n=100) and confirmatory analysis (CFA) (n=184) were performed. ResultsAn alpha of .927 was obtained, and evidence for criteria validity was assessed with stress measures (rs=-.391) and anxiety (rs=-.401) The exploratory factor analysis (EFA) determined a bifactorial structure that explains 68.07% of the variance. Confirmatory factor analysis (CFA) showed good composite reliability (CR>.8) and an adequate average variance was extracted (AAV>.5) from both latent variables. ConclusionsThe bifactorial structure is confirmed to assess family and partner's social support in pregnant women with the AFA-R's adapted version.
