Validation of the Inventaire du Milieu Familial Questionnaire (French version of the Infant/Toddler HOME) into the Brazilian Portuguese language

Abstract

ObjectiveTo validate the Brazilian Portuguese version of the Family Environment Assessment questionnaire (Inventaire du Milieu Familial). MethodsThe validation process was carried out in two stages. First, translation and back-translation were performed, and in the second phase, the questionnaire was applied in 72 families of children between 0 and 24 months for the validation process. The tool consists of the following domains: mother's communication ability; behavior; organization of the physical and temporal environment; collection/quantity of toys; maternal attitude of constant attention toward her baby; diversification of stimuli; baby's behavior. The following was performed for the scale validation: 1 – content analysis (judgment); 2 – construct analysis (factorial analysis – Kaiser-Meyer-Olkin, Bartlett, and Pearson's correlation tests); 3 – criterion analysis (calculation of Cronbach's alpha coefficient, intraclass correlations, and split-half correlations). ResultsThe mean age of the children was 9±6.7 months, and of these, 35 (48.6%) were males. Most correlations between items and domains were significant. In the factorial analysis of the scale, Kaiser-Meyer-Olkin values were 0.76, Bartlett's test showed a p-value<0.001, and correlation between items and domains showed a p-value<0.01. Regarding the validity, Cronbach's alpha was 0.92 (95% CI: 0.89–0.94). The intraclass correlation among the evaluators was 0.97 (0.96–0.98) and split-half correlations, r: 0.60, with p<0.01. ConclusionsThe Portuguese version of the Inventaire du Milieu Familial showed good to excellent performance regarding the assessed psychometric properties.
