Positive family relationships: Longitudinal network of relations.

The construct of positive family relationships (PFR), defined as family members getting along well and supporting each other, was investigated in a long-term prospective study. A newly constructed scale of positive family relationships developed using the nominal response model of item-response theory, was subject to a longitudinal network of relations analysis. The conceptualization for this research was founded on a positive psychology framework. Data derived from the Fullerton Longitudinal Study and spanned 20 years from middle childhood (age 9 years) to early adulthood (age 29 years). Evidence indicated both stability and change in PFR across time. Moderate to high stability of individual differences among families across 9 annual assessments was found from ages 9-17 years. Concomitantly across these years, there was a progressive decline in PFR. PFR proved to be independent of socioeconomic status. Specific conceptually based directional hypotheses were tested using structural equation modeling. Multiple sources of information included intra- and cross-informant, as well as objective and ecologically valid data. The network of relations involved concurrent and predictive criterion-related variables. PFR had a pervasive relation to a variety of psychological domains across time. As predicted, PFR related (a) positively to family cohesion and inversely to family conflict, (b) positively to parental social support, (c) positively to children's self-concept, (d) positively to children's academic performance and educational attainment, and (e) inversely to children's behavior problems. The theoretical importance of the findings and the applicability of the PFR Scale for both researchers and practitioners in the field of family psychology are discussed.
