Measuring adolescent patients’ engagement in their health care is especially important in preparing for chronically ill adolescents’ transition into adult care. In this study, we aimed to create an adolescent version of the German language Patient Activation Measure (PAM‐13‐D) originally tested in in adults and psychometrically test the adapted measure (PAM ® 13 for Adolescents). After linguistic and content‐related adaptations, the PAM ® 13 for Adolescents was tested in a large sample of adolescents with different chronic conditions ( N = 586, mean age 17.5 years, SD = 1.4) in 40 health centers. Internal consistency was assessed with Cronbach's alpha and test–retest reliability with Pearson correlation. Convergent and divergent validity were calculated with Pearson correlations between the two IE‐4 scales (internal and external Locus of Control) and the PAM ® 13 for Adolescents. Known‐group validity (type 1 diabetes vs. IBD, higher vs. lower education level) was checked by Mann–Whitney‐ U ‐tests. The PAM ® 13 for Adolescents showed good test–retest reliability (rtt = .68), internal consistency ( α = .79) and demonstrated good validity. The original structure of the PAM 13‐D was replicated. Rasch analysis using the partial credit model was used to investigate the operating characteristics of the items. Rasch analysis indicated a sufficient fit of 12 of the 13 items. PAM ® 13 for Adolescents is the first instrument measuring patient activation of adolescents with chronic conditions in a broad age range. Patient activation level can be used by clinicians to better plan and structure transition processes.
