The Family‐Centred Practices Scale: Psychometric properties of the Spanish version for use with families with children with Down syndrome receiving early childhood intervention

摘要

Abstract Background The Family‐Centred Practices Scale (FCPS) assesses the degree to which staff in early childhood intervention and development centres use this therapeutic approach. However, there is no adaptation of this scale to families of children with Down syndrome, which is one of the most prevalent intellectual disabilities in early intervention. Objectives To validate and analyse the psychometric properties of the FCPS in Spanish parents with children with Down syndrome receiving early childhood intervention. Methods Descriptive analyses, exploratory factor analysis (n?=?131), confirmatory factor analysis (n?=?126) and scale reliability analyses were performed. In addition, the invariance of the scale by parents' age and gender was assessed, and a longitudinal analysis of the scores was performed. Results A new scale was obtained with a two‐factor structure, similar to the original version, but with fewer items. Goodness‐of‐fit indices were excellent (root mean square error of approximation [RMSEA] [95% confidence interval {CI}]?=?0.02 [0.01; 0.04]; comparative fit index [CFI]?=?0.98; Tucker–Lewis index [TLI]?=?0.97; root mean residual [RMR]?=?0.02; goodness‐of‐fit index [GFI]?=?0.91; adjusted GFI [AGFI]?=?0.90). However, the measure was not gender invariant. Additionally, internal consistency of the two dimensions showed high values in this sample, and comparing the means between the two measurement time points (initial and at about 6?months) showed no differences; the test was powerful but had a very small effect size. Conclusions The psychometric properties of this FCPS are adequate, and it uses fewer items, which makes it faster to apply and gives it better clinical applicability. This new version of the scale is a valid, reliable tool for evaluating family‐centred practices in Spanish families with children with Down syndrome.
