Psychometric Properties of the Hebrew Translation of the Patient Activation Measure (PAM-13)

Objective: "Patient activation'' reflects involvement in managing ones health. This cross-sectional study assessed the psychometric properties of the Hebrew translation (PAM-H) of the PAM-13. Methods: A nationally representative sample of 203 Hebrew-speaking Israeli adults answered the PAM-H, PHQ-9 depression scale, SF-12, and Self-efficacy Scale via telephone. Results: Mean PAM-H scores were 70.7 +/- 15.4. Rasch analysis indicated that the PAM-H is a good measure of activation. There were no differences in PAM-H scores based on gender, age or education. Subjects with chronic disease scored lower than those without. Scores correlated with the Self-efficacy Scale (0.47), Total SF-12 (0.39) and PHQ-9 (-0.35, P<0.0001), indicating concurrent validity. Discriminant validity was reflected by a significant difference in the mean PAM-H score of those who scored below 10 (72.1 +/- 14.8) on the PHQ-9 (not depressed) compared to those scoring >= 10 (i.e. probable depression) (59.2 +/- 15.8; t 3.75; P = 0.001). Conclusion: The PAM-H psychometric properties indicate its usefulness with the Hebrew-speaking Israeli population.
