Psychometric Properties and Cultural Adaptation of the Polish Version of the Healthy Lifestyle and Personal Control Questionnaire (HLPCQ).

Background: Chronic non-communicable diseases (NCDs), sometimes referred to as lifestyle diseases, are the most common cause of death and disability worldwide. Thus, healthcare professionals should be equipped with tools, knowledge, skills, and competencies in the newly distinguished field of lifestyle medicine. The purpose of this study was to test the psychometric properties of the Polish version of the Healthy Lifestyle and Personal Control Questionnaire (HLPCQ). The Polish version of the HLPCQ would further provide Polish healthcare professionals with a useful and convenient tool for routine lifestyle assessment while giving HLPCQ novel use and potential for further research.

Methods: Before testing its psychometric properties, the HLPCQ was translated and adapted from the original Greek version into Polish. Subsequently, we tested the instrument's psychometric properties on a sample of 2433 participants. In addition, we tested the factorial validity of the HLPCQ using confirmatory and exploratory factor analysis.

Results: There were more female than male participants (91.78%). Most of them were middle-aged (30.40 ± 7.71), single (39.62%), and living with family (70.65%). In terms of residence, 1122 (46.12%) participants lived in cities with a population of over 500,000. In terms of reliability, the internal consistency of the Polish version and its domains is excellent. Cronbach's alpha for each of the domains of the scale ranged between 0.6 and 0.9.

Conclusions: The Polish version of the Healthy Lifestyle and Personal Control Questionnaire (HLPCQ) has good characteristics of factorial validity and can be used in clinical practice and research.
