Creation and validation of an instrument to quantify attitudes, knowledge and difficulties in the approach to social problems

Abstract

ObjectivesThe aim of the study was to develop and validate a questionnaire to assess attitudes, knowledge and difficulties in the management of social problems by paediatric care providers. MethodsThe development of the tool started with a conceptualization phase, followed by the design, pilot testing and psychometric evaluation of the questionnaire based on the responses obtained from 407 professionals. We performed exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to assess the construct validity of the questionnaire. We used the normed fit index (NFI), the root mean square error of approximation (RMSEA), the χ2 test and the comparative fit index (CFI) to test the goodness of fit. We assessed reliability through the Cronbach’s α coefficient of internal consistency. All quantitative analyses were performed with the Stata/SE software, version16.1. ResultsThe EFA identified twelve factors. All factors exhibited a good internal consistency (Cronbach’s α, 0.8434). The CFA showed the model was a good fit (RMSEA=0.037). The NAI and CAI values were 0.742 and 0.797, respectively. ConclusionsThis questionnaire comprising 138 items distributed in twelve factors is a reliable and valid instrument to analyse the attitudes, knowledge and difficulties in the approach to social problems in children by paediatricians, which will allow the design of interventions according to the needs and deficiencies identified through it.
