The Adapted DUKE-UNC Functional Social Support Questionnaire in a Community Sample of Portuguese Parents

Purpose: Social support measures have generated empirical evidence of helping relationships and their role in family functioning and well-being. Social support networks affect parental practices and the ways in which families overcome stressful life events. Thus, it is important to gather knowledge about the different forms of support that families can benefit from. The aim of this study was to translate, adapt, and validate the Portuguese version of the Duke-UNC Functional Social Support Questionnaire (FSSQ), a three dimension measure (confidant support, affective support, and instrumental support), Method: 1058 Portuguese parents participated in the study. They were mostly married/cohabiting and employed mothers. The Portuguese version of the FSSQ contained 13 items distributed into 3 subdimensions. The data were analyzed using confirmatory factor analysis and the study of Pearson correlations. Results: The FSSQ original three-factor structure was supported by confirmatory factor analysis and the instrument showed good internal consistency. Confidant support and Instrumental support were negatively associated with Permissive parenting and Affective support was negatively associated with Authoritative parenting and Permissive parenting. All three dimensions showed low and positive correlations with Authoritarian parenting. Discussion: The Portuguese version of the FSSQ met adequate psychometric criteria and can be confidently used in family assessments of social support, whenever a brief, self-administered questionnaire would be useful for community services providers
