- Abstract:
- Introduction Patient activation describes the confidence, skills and knowledge in managing ones own disease. It can be assessed by the Patient Activation Measure® (PAM). The main objective of the thesis is to investigate the psychometric properties of the German PAM® survey in patients with chronic diseases. Methods Outpatients with macular edema participated in this questionnaire-based cross-sectional study. Through interviews, patient activation, self-rated health, self-efficacy, quality of life, general mood and health information seeking were assessed. Psychometric properties were investigated using item response theory (IRT), Cronbach's α and trait-trait correlations. Results 554 patients were included in the final analysis. The median age was 69 (IQR: 62.0 76.0) years. The study sample showed a mean overall activation score of 74.1 (SD: 13.7). All items showed ceiling eects. Empirical reliability from the IRT model and Cronbach's α were 0.75. The PAM® survey showed a Spearman correlation of 0.54 (p<.001) with self-efficacy, 0.51 (p<.001) with quality of life, 0.34 (p<.001) with general mood and 0.27 (p<.001) with health information seeking. Discussion The PAM® survey reliably assesses patient activation in an everyday clinical setting, and it is also a valid measurement tool. Objective assessment in an interview setting with the PAM® survey is possible. Patients with low patient activation are identied with the questionnaire. Measurement quality deteriorates for those with high activation ability level, as items oer little information to distinguish between them. In general, patients were highly activated, indicating they are already engaged in the management of their health.
