Measuring Social Support from Mother-Figures in the Transition from Pregnancy to Parenthood among Mexican-Origin Adolescent Mothers.

Social support for adolescent mothers, particularly from mother figures, can buffer risks and promote well-being. To date, no longitudinal research has investigated how the dimensions of social support may change during the transition from pregnancy to parenthood for adolescent mothers. This study examined stability and change in dimensions of social support from the third trimester of pregnancy to two years postpartum among 191 dyads of Mexican-origin adolescent first-time mothers and their mother figures. Perceptions of social support received from a mother figure shifted from a single dimension (i.e., global support) to three distinct factors (instrumental, emotional, and companionship support) during this transition; however, social support provision as reported by mother figures remained stable. Measurement equivalence was established across interview language (English and Spanish) and across two time points postpartum. Bivariate correlations provided support for the convergent and divergent validity of these measures. Implications for future research and practice are discussed.
