The internal consistency and construct validity of the partners in health scale: validation of a patient rated chronic condition self-management measure

Abstract

Please note that any alterations made during the publishing process may not appear in this version. Please refer to the published article cited above. MethodsBaseline PIH data were collected for 294 patients with a range of co-morbid chronic conditions including diabetes, cardiovascular disease and arthritis. Scale data were analyzed for internal consistency and construct validity using Reliability Analysis and Factor Analysis. Construct validity was established using confirmatory factor analysis and a structural equation model. ResultsResults show a Cronbach alpha value of .82 and highlight four key factors (knowledge, coping, management of condition and adherence to treatment) across the twelve domains of the scale. These four key factors were then confirmed by applying the exploratory structural equation model to a hold-back sample of 118 patients. ConclusionThe PIH scale has been shown to exhibit construct validity and internal reliability.It therefore provides a relevant measure of health related outcomes for patients involved in chronic illness management and self-management programmes currently being implemented across Australia and around the world.

Validation study of a Chinese version of Partners in Health in Hong Kong (C-PIH HK)

“…The C-PIH(HK) had a slightly different factor structure when compared to the Petkov's study [4]. Four factors were identified in the Petkov's study, and three factors were idenified in the C-PIH(HK) study.…”

“…Factor analysis supported a 3-factor solution (Cronbach's alpha = 0.88) [3]. Later, two 12-item versions were developed (version A and version B 1 ) [4,5] and demonstrated good construct validity and internal consistency in the English, Spanish, and Dutch versions (Cronbach's alphas ranged from 0.66 to 0.82) [4,6,7]. The PIH has been used to validate the Multiple Sclerosis Self-Management Scale [8].…”

Use and effects of patient online access to medical records in general practice through a personal health record in the Netherlands. A protocol for a mixed methods study. (Preprint)

“…We will use the Partners in Health scale (PIH) [40] to assess effects on patients' perceived knowledge about their conditions and treatment (two items), patients' taking an active role in their treatment (four items) and patients' recognition and management of symptoms (two items). This scale has been developed in Australia to assess patients' skills to be involved in self-management and used in the Netherlands among ambulant patients with chronic diseases and demonstrated adequate internal consistency, with a Cronbach's alpha coefficient (α) of 0.69 for active role, 0.89 for knowledge, 0.66 for recognition and management of symptoms [40,41].…”

The effects of patient–professional partnerships on the self-management and health outcomes for patients with chronic back pain: A quasi-experimental study

“…A higher 2 score represents better self-management practice. The PIH scale has been shown to have 3 high internal consistency (Cronbach's alpha=0.82) (Petkov et al, 2010). 4…”
