Psychometric Properties of the Turkish Version of the Partners in Health Scale: Chronic Disease Self-Management in Primary Healthcare

Background: This study aimed to assess the psychometric properties of the Turkish version of the Partners in Health Scale (PIH-TR), which was developed to assess the perceptions of patients with chronic conditions in primary care. Accurate assessment of facilitators and barriers to self-management of chronic conditions, from the patients' perspective, is important for working effectively with them to promote better health outcomes. Methods: A cross-sectional validation study was conducted and designed according to the STROBE guidelines. One hundred thirty-six patients, aged 30–90 years (86.7% aged > 60), were recruited from family care centres. Data were collected using the revised PIH, an adapted version of Model-2 (PIH-TR), which is a 12-item self-rated measure of self-management of chronic conditions. The PIH was translated into Turkish using Beaton et al.'s method. Content, construct validity and internal consistency analyses were undertaken to evaluate the data. Results: The PIH-TR had satisfactory reliability and validity and revealed a four-factor structure appropriate to the original scale: knowledge, partnership in treatment, recognition and management of symptoms and coping. Omega coefficient (0.860), test–retest reliability (0.841) and comparative fit indices (CFI) (0.99) were high. Conclusion: The PIH-TR has good specifics and is reliable and valid as an objective self-rated tool to assess self-management of Turkish patients' chronic conditions.
