Model-based validation of the Slovenian 20-item version of the Measure of Processes of Care

Gregor Sočan, Katja Groleger Sršen, Gaj Vidmar, Anton Zupan


Rationale and aims: The Measure of Processes of Care (MPOC-20) is a self-administered questionnaire for parents of chronically ill or disabled children to report on their experiences of the care process. The aim of this study was to investigate the construct validity of the Slovenian adaptation of MPOC-20.

Method: One hundred and seventy-four parents of children with a chronic illness/disability, treated at 7 public healthcare institutions in Slovenia, completed MPOC-20 and a questionnaire about their child, themselves and their family.

Results: The slightly modified measurement model fitted well to the data. The model was then extended into a structural regression model, which included several predictors of MPOC-20 latent factors. The child’s gender and the presence of a key worker emerged as the most relevant predictors.

Conclusions: We propose a small change in the scoring of MPOC-20. The presence of a key worker improves the parents’ evaluation of the processes of care for their child.
