The association between demographic and familial characteristics and psychological properties of adolescents

Background: We aimed to investigate the association between demographic and familial characteristics and psychological properties of adolescents including identity style, spiritual intelligence (SI), perceived parenting style (PPS), family functioning, and mental health.

Materials and methods: In this cross-sectional study, high school students aged 15-18 years were enrolled. Demographic characteristics of each student and their parents were recorded. Psychological properties of the students including PPS questionnaire, family assessment device, identity status, mental health status, and SI were assessed. The association between demographic and familial characteristics and psychological properties of adolescents was determined using Multiple Indicators and Multiple Causes (MIMIC) model.

Results: In this study, 279 high school students (140 boys and 139 girls) were enrolled. The most common forms of identity style were diffusion and foreclosure with a prevalence rate of 49.1% and 39.5%, respectively. Results of MIMIC model showed acceptable fit with comparative fit index = 0.91, Tucker-Lewis index = 0.87, and root-mean-square error of approximation = 0.05 (0.04-0.06). There was a significant positive association between age and family functioning (P = 0.001). There was a significant positive association between age and mental health (P = 0.003). There was a significant negative association between gender and PPS (P < 0.001). The most common forms of PPS in females and males were authoritative form and uninvolved parenting, respectively. There was a significant positive association between father education and PPS (P = 0.001).

Conclusion: Our findings indicated that there is an association between families' demographic characteristics and identity style, perceived parental style, family functioning, and SI of adolescence. The association of some factors with mentioned psychological variables is more prominent such as age, gender, and father age.
