Construct validation of the Greek version of the Children's Assessment of Participation and Enjoyment (CAPE) and Preferences for Activities of Children (PAC).

BACKGROUND The Children's Assessment of Participation and Enjoyment (CAPE) and the Preferences for Activities of Children (PAC) are 2 measures of children's participation in various activities. The purpose of this study was the validation of the Greek version of "CAPE & PAC." METHODS The questionnaires were translated and pilot tested on a sample of 25 individuals. The reliability and validity of the questionnaires were tested on 302 individuals (253 typical population, 49 disabled), 6-21 years of age. The construct validity of the instruments was examined the directional hypothesis by comparing known groups with existing differences. An exploratory factor analysis was conducted to determine the validity of the typology of activities. The reliability was examined by checking the internal consistency of the instruments. RESULTS The comparison between divergent groups confirmed the predicted differences of the mean scores and the validity of the instruments. Seven factors (categories of activities) emerged from the factor analysis. The acceptable range of Cronbach alpha for the PAC scale indicated high consistency. CONCLUSION This study provides evidence that partially support the validity and reliability of "CAPE & PAC" instruments to use in Greek population. Further investigation is recommended for both clinical and research purposes.
