Developing and Testing a Measure of Social Support With Mexican-Origin Pregnant Adolescents and Their Mother Figures

The current study describes the development and psychometric testing of the Global Support From Mother Figure During Pregnancy Scale (GSMF-P). The measure is developed in both Spanish and English to assess social support provided to adolescents during their pregnancies. The current study examines the reliability, cross-language equivalence, and validity of the scale with a sample of 207 pregnant, Mexican-origin adolescents ( M age = 16.2, SD = 0.98) and their mother figures ( M age = 40.9, SD = 7.01). The scale demonstrates strong internal consistency across reporters and language versions. Furthermore, findings provide support for the measurement equivalence of the English and Spanish versions. Finally, all construct validity hypotheses are supported, providing initial evidence that the GSMF-P appears to be assessing the construct of mother figure social support from both adolescents’ and mother figures’ perspectives.
