Dyadic analysis of the inventory of family integration in fathers and mothers in the city of Arequipa

The present study analyzes the psychometric properties of the Inventory of Family Integration (IFI) by means of a dyadic analysis based on the responses of fathers and mothers in families from the city of Arequipa, southern Peru. For this purpose, 264 married couples living with their families were non-probabilistically selected and administered the 52-item IFI. An analysis of dimensionality and reliability was carried out, and a factorial invariance analysis was applied under a dyadic approach and, finally, a comparative analysis using Cohen's d was performed. The results reported moderate correlations between the values of fathers and mothers in each family holon: Personal, spousal, parental, sibling and familial. Likewise, the dimensionality fit of each holon in fathers and mothers was adequate with acceptable magnitudes, and the reliability indices calculated with Cronbach's alpha and McDonald's Omega tests were high. The five- factor internal structure and internal consistency in both fathers and mothers were corroborated.
