Validation Study of the Portuguese Version of the Family Problem Solving Communication (FPSC) Index

Within family stress theories, the way in which families communicate about their hardships and issues is crucial for the family’s stress management and functioning. In the current study, we sought to validate the Portuguese version of the Family Problem Solving Communication (FPSC) Index and examine its psychometric properties. Developed within the context of the resiliency model of family stress, adjustment and adaptation, the FPSC is a ten-item self-report measure that assesses the family communication patterns that are likely to play a role in the family’s coping with hardships and difficulties. The participants were 332 individuals between 18 and 76 years who completed the FPSC and self-report measures of family hardiness and family functioning. A confirmatory factor analysis supported the original FPSC bifactorial structure, indicating the presence of two dimensions, Affirmative Communication and Incendiary Communication. Correlations between the scale’s total score and its dimensions with the measures of family hardiness and family functioning attested to its convergent validity. Furthermore, the index demonstrated respectable to very good internal consistency and temporal stability. In conclusion, the Portuguese version of the FPSC is a valid and reliable instrument that can support the development of future empirical studies focused on family problem solving communication, especially with regard to family adaptation in different contexts of adversity.
