Cross-Cultural adaptation of the General Functioning Scale of the Family

Abstract

OBJECTIVE To describe the process of cross-cultural adaptation of the General Functioning Scale of the Family, a subscale of the McMaster Family Assessment Device, for the Brazilian population.METHODS The General Functioning Scale of the Family was translated into Portuguese and administered to 500 guardians of children in the second grade of elementary school in public schools of Sao Gonçalo, Rio de Janeiro, Southeastern Brazil. The types of equivalences investigated were: conceptual and of items, semantic, operational, and measurement. The study involved discussions with experts, translations and back-translations of the instrument, and psychometric assessment. Reliability and validity studies were carried out by internal consistency testing (Cronbach’s alpha), Guttman split-half correlation model, Pearson correlation coefficient, and confirmatory factor analysis. Associations between General Functioning of the Family and variables theoretically associated with the theme (father’s or mother’s drunkenness and violence between parents) were estimated by odds ratio.RESULTS Semantic equivalence was between 90.0% and 100%. Cronbach’s alpha ranged from 0.79 to 0.81, indicating good internal consistency of the instrument. Pearson correlation coefficient ranged between 0.303 and 0.549. Statistical association was found between the general functioning of the family score and the theoretically related variables, as well as good fit quality of the confirmatory analysis model.CONCLUSIONS The results indicate the feasibility of administering the instrument to the Brazilian population, as it is easy to understand and a good measurement of the construct of interest.

Cross-Cultural Adaptation of the General Functioning Subscale of the McMaster Family Assessment Device

“…The reliability of the Malay GF12 was tested in terms of internal consistency and test-retest reliability whereby ndings were in agreement with the Spanish and French FAD-GF12 studies 34,35 . The Cronbach alpha of the Malay GF12 was 0.89 which indicates a high level of internal consistency supporting the previous ndings of Spanish and Dutch versions 20,36 .…”

Transcultural adaptation of the Thirst Distress Scale (TDS) into Brazilian Portuguese and an analysis of the psychometric properties of the scale for patients on hemodialysis

“…In the scale adapted for patients with heart failure, "algodão" (cotton) was replaced with "lixa" (sandpaper), 19 a more adequate term in Portuguese to express a sensation of roughness rather than dryness. 24 In the Turkish adaptation, the term "cotton" was suppressed and the item read "my mouth gets really dry when I am thirsty." 18 Item 5 remained unchanged in our and other adaptations.…”

“…The study included 126 patients, a sample size characteristically seen in validation studies. [23][24][25][26] Data collection took place in the morning, afternoon, and evening shifts during HD sessions. The questionnaire included identification information and probed into etiology of CKD, time on HD, KT/V (a marker of quality of dialysis), comorbidities, body mass index (BMI), interdialytic weight gain (an indicator of fluid status), biochemical tests (transferrin, hemoglobin, ferritin, albumin, creatinine, pre-dialysis blood urea nitrogen, post-dialysis blood urea nitrogen).…”

Internal construct validity of a Brazilian version of the McMaster Family Assessment Device

“…It is important to consider this study as a possible solution or at least a proposal to be taken into account in further studies about the cross-cultural adaptation of the assessment tool to the Brazilian reality. In this context, Pires et al 23 have indicated another Brazilian version of FAD, which they stated revealed a good applicability, easy understanding by the population, and good measurement of the construct of interest.…”
