Propriedades psicométricas do autoquestionnaire qualité de vie enfant imagé (auqei) aplicado em crianças com paralisia cerebral

The present study aims to evaluate the psychometric properties of the Brazilian version of the Autoquestionnaire Qualité de Vie Enfant Imagé (AUQEI), applied to children with cerebral palsy. The questionary was answered by 45 children with cerebral palsy and 45 healthy children aged 5 to 12 years. The following psychometric properties of the AUQEI were evaluated: data quality (missing data, floor effect and ceiling effect), reliability and validity. The missing data rate varied from 8.8% to 46.7% among the factors, being the largest value found in the autonomy dominion. The floor effect was 0% for the factors. The ceiling effect varied 0 to 4.4% among the factors. In assessing the reliability of the internal consistency of the item the success rate was less than 80.0% only for the autonomy factor (40.0%). The Cronbach alpha coefficient was 0.71 for the general analysis of the instrument and 80.0% for discriminated validity of the item. The factors were not correlated with each other, in general, indicating adequate discriminated validity. Only the function factor had correlations with the family factors (r = 0.47 and p0,05), in the assessment of divergent validity. In the construct validity, the total score obtained by AUQEI the patients group was lower (median: 47.0) than the healthy group (median: 51.0) (p 80,0% para validade discriminante do item. Os fatores não tiveram correlação entre si, em geral, indicando adequada validade discriminante. Apenas o fator função teve correlações com os fatores família (r = 0,47 e p0,05), na avaliação da validade divergente. Na validade de construto, o escore total do AUQEI obtido pelo grupo de pacientes foi menor (mediana: 47,0) que o do grupo saudável (mediana: 51,0) (p
