Methods: Data from the National Survey of American Life was used for the secondary data analysis. Respondents who had a diagnosis on the spectrum of mood and anxiety disorders were included (n=1,003). Samples were predominantly female (71.6%) and non-White (78.4%). Social support in this study was measured using Likert scale items, having 4 to 7 response options. The Structured Means Model (SMM) was administered to compare the means differences between emerging (n=152) and mature adults (n=851). Emerging adults in the current study were defined as adults aged 18 to 25 whereas mature adults were defined as those aged 26 or older.
Results: The SMM results supported the partial strong invariance of three-factor model of social support between emerging and mature adults with mood and anxiety disorders (Chi-square(df=88)=222.375, p<.001; RMSEA=.055; 90% CI = .046, .064; CFI=.965; TLI=.956). Therefore, factor means of family support, family negative interactions, and friend support were compared. Results revealed that emerging adults with MAD, as compared to mature adults with those diagnoses, had lower family support (B=-.152, p=.007) and higher family negative interactions (B=.419, p<.001); but the level of friends support was not statistically different (B=.058, p=.626). Standardized effects sizes suggested that the magnitude of the differences in factor means of family support (ESfs=.582) and family negative interactions (ESfn=.600) were medium.
Conclusions and implications: Findings revealed that social support characteristics of emerging adults with MAD significantly differ from mature adults with MAD in terms of family relationships, rather than friend relationships. This implies that emerging adults with MAD experience difficulties related to family, even more than individuals with the same diagnoses in older ages. Family interventions are particularly important for emerging adults with MAD. Future research and interventions should take into account the uniqueness of social support in this population.
