The present study aimed to evaluate the construct validity and factor structure of the Spanish language version of the SSQ-6 during early pregnancy.Participants and methods: A total of 4,236 pregnant Peruvian women were interviewed at 10.3 ± 3.8 weeks of gestation.In-person interviewers were used to collect lifestyle, demographic, and social support characteristics.
The construct click here validity and factorial structure of the SSQ-6 were assessed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).The internal consistency was evaluated using Cronbach’s alpha.Results: The mean SSQ-6 score was 39.6 ± 6.8 and Cronbach’s alpha was 0.
83.EFA resulted in a three-factor solution that accounted for 60.6% of the variance.CFA results confirmed the three-factor structure and yielded measures indicating goodness of fit (comparative fit index of 0.9401) and accuracy (root mean square error of approximation of 0.
0394).Conclusion: Although the SSQ-6 was originally developed as a two-factor model, and previous studies have supported this, in our study a three-factor model was found to be more appropriate.The SSQ-6 was found to have good construct validity and reliability for assessing social support.Keywords: social support, SSQ-6, pregnancy, validation.
