Empirical Articles Contributos Para a Validação Portuguesa do Family Relationship Index ( FRI ) Reduzido Contributions to the Portuguese Validation of the Reduced Family Relationship Index ( FRI )

Aim: Considering the importance of relationships and family functioning in the psychological well-being of its members and in the development of psychopathology, this study aimed to contribute to the Portuguese validation of the reduced version of the Family Relationship Index (FRI). Methods: The sample was composed of 193 Portuguese participants who responded to an online questionnaire. Participants were mostly female (65.3%), with an average age of 44.65 years, and 63.2% were married. Results: Confirmatory factor analysis of the scale resulted in two factors (conflict and cohesion/expressiveness), instead of three, as in the original scale, and the final factor model showed good levels of adjustment quality. The internal consistency for the cohesion/ expressiveness factor was 0.902 and 0.741 for the conflict factor. With the exception of item six, the other items of FRI presented factor weights greater than 0.5, and all items were statistically significant. Concerning family types, results reveal that most families belonged to conflict resolving type (34.7%). Conclusion: In conclusion, this instrument has good internal consistency and construct reliability, so it can be useful for the identification of dysfunctional families.
