The Patient Assessment of Chronic Illness Care (PACIC-5A) was developed to assess the satisfaction with patient-provider interaction based on the Chronic Care Model. The additional 5A approach (assess, advise, agree, assist, arrange) allows to score behavioral counseling. The aim of the study was to assess the psychometric properties of the German adaptation of the PACIC-5A questionnaire in a sample of general practitioners (GP) patients with obesity. Analyses were based on data from the study “Five A’s counseling in weight management of obese patients in primary care: a cluster randomized controlled trial (INTERACT)”. Data were collected via standardized questionnaires containing the 26-item version of the PACIC-5A questionnaire. A total of 117 patients with obesity were included in the analyses. Statistical procedures comprised descriptive analyses, the calculation of Cronbach’s alpha, test-retest analyses and factor analyses in order to assess the psychometric properties including reliability and validity of the PACIC-5A. The patient’s mean age was 43.4 years and the sample was mostly female (59%). Middle educational level was found for the majority (78%) and the mean Body Mass Index was 38.9 kg/m2. Descriptive analyses revealed a mean PACIC score of 2.33 and 5A sum score of 2.29. Notable floor effects were found. PACIC-5A showed high level of internal consistency (Cronbach’s alphas > 0.9) and exploratory factor analyses resulted in a unidimensional structure. The results of this study provide evidence regarding the psychometric properties of the German version of the PACIC-5A used in a sample of GP patients with obesity and make an important contribution to the reliable and valid assessment of the patient-GP interaction with regard to obesity counseling in primary care.
