Evaluation of the psychometric properties of the Polish adaption of the questionnaire for assessment of parental satisfaction in pediatric outpatient care

Introduction
In Poland, outpatient care has not yet been tested with validated tools. Many care providers use author's questionnaires that, which do not have their psycho-metric properties evaluated, which may result in misinterpretation of the expectations of patients and their parents. The use of standardized research tools is a prerequisite for obtaining reliable test results.

Objective
The aim of the study was to adapt the German Kinder ZAP questionnaire to evaluate the satisfaction of the parent with pediatric outpatient care, both from the perspective of the patient and himself.

Material and methods
The Polish version of the Kinder ZAP questionnaire was developed in accordance with the standards of adaptation and tool validation. The psychometric properties of the tool were tested on a sample of 362 parents with developmental progeny. The collected data were analyzed by factorial method with varimax rotation and confirmatory analysis. The reliability of each test scale was determined by the Cronbach alpha coefficient.

Results
During the analysis, 8 factors were identified in two blocks: for parental assessment (5 factors) and child (3 factors). The internal structure of the created tool was a replica of the Kinder ZAP questionnaire, both in terms of the number and content of the questions assigned to each factor. The selected factors served as a basis for the construction of the target scales of the Polish adaptation of the tool. Each of the scales was characterized by high reliability (o = 0.82-0.97).

Conclusion
Providing high quality medical services requires direct reference to the practitioner (patients and their families) through reliable measurement of satisfaction with health care. The Polish version of the Kinder ZAP questionnaire can be used to measure the satisfaction of outpatient pediatric care both from the perspective of the parent and the child.
