Objective: In the present study we aim to assess the reliability and validity of the 20-item version of the Dutch Measure of Processes of Care (MPOC).
Design: The reliability, concurrent validity, predictive validity and construct validity of the Dutch MPOC-20 were determined. A subset of MPOC-20 data was extracted from a large Dutch MPOC (56-item version) database.
Subjects: Participants were 405 mothers and 22 fathers of children aged 1-18 years recruited through nine paediatric rehabilitation centres in the Netherlands.
Main measures: The participants filled out the MPOC-20 items, the Client Satisfaction Questionnaire (CSQ), and two additional questions about satisfaction with services and the amount of stress they experienced.
Results: The internal consistency analyses (alphas 0.75-0.87) and the test-retest analyses (intraclass correlation coefficients (ICCs) 0.78-0.91) showed that the Dutch MPOC-20 is a reliable tool. The concurrent validity of the Dutch MPOC-20 was confirmed by positive correlations between MPOC-20 scale scores and the CSQ (r 0.39-0.69), and between MPOC-20 scale scores and an overall satisfaction variable (r 0.37-0.66). The predictive validity of the Dutch MPOC-20 was supported by moderately negative correlations between MPOC-20 scores and a stress variable (r -0.27 to -0.44). The construct validity of the Dutch MPOC-20 was confirmed by significant scale intercorrelations (r 0.41-0.84) and a factor analysis.
Conclusions: The 20-item version of the MPOC (Dutch MPOC-20) is a reliable and valid measure of the family-centredness of paediatric rehabilitation.
