Objectives: A significant body of research suggests that patient motivation is related to better rehabilitation outcome with regard to psychosocial and physical well-being. Thus, patient motivation gains increasing attention with regard to the course of treatment and individual treatment planning in the practice and research in medical rehabilitation. This study aims to validate the PAREMO-20, a measure of rehabilitation motivation in a sample of cancer patients with different tumour sites. Methods: 1193 cancer patients participated in a prospective study evaluating the medical and psychosocial effects of inpatient cancer rehabilitation. A set of various questionnaires was completed at the beginning and at the end of the rehabilitation measure as well as at one year follow-up (participation rate at follow-up: 78%). The PAREMO-20 was psychometrically examined on this sample. Validity was examined using a cancer-specific questionnaire for individual therapy goals, as well as the HADS-D and the SF-8. Results: The original six factors were replicated. The factor solution emerging through PCA was tested with a confirmatory factor analysis. Maximum likelihood estimation of this model produced good fit statistics. Internal consistencies were high to satisfactory with Cronbach's Alpha =0.88 to Alpha = 0.59. Psychological distress and physical impairments were positively associated with anxiety and depression, as well as with therapy goal dimensions. Moderate to high (negative) correlations were observed with health related quality of life, in particular with the mental-health dimension (r= -0.74, p=0.01 ). Discussion: The PAREMO-20 is a reliable, valid and economic instrument, which can be recommended for use in clinical care. © Georg Thieme Verlag KC Stuttgart New York. |
