[Patient expectations regarding methods and outcomes of their rehabilitation--a controlled study of back pain- and cancer patients].

Although patient expectations are important factors of the success of rehabilitation, they have not yet received much attention in research. In the present cross-sectional study, n = 248 rehabilitation patients, n = 160 suffering from chronic back pain and n = 88 suffering from oncological diseases (breast cancer, cervical cancer, ovarian cancer, colorectal cancer), were assessed at the time of admission to a rehabilitation clinic, using a newly developed self-report questionnaire to evaluate their expectations regarding the process and outcome of their rehabilitation. Results show on an item level that non-specific process expectations such as balneophysical treatments or features of the surroundings of the clinic were most prevailing. Across both diagnostic groups, common goals of rehabilitation such as reduction of complaints, physical fitness and recreation scored highest. On the basis of factor analysis, 10 scales of process expectations were constructed: medical attention, physical training, vocational counselling, balneophysical treatment, health information, stress management training, support groups, relief from the strains of everyday life, alternative medicine, and pleasant surroundings. Nine dimensions of outcome expectations were detected: ability for work, physical fitness, reduction of complaints, behaviour change, reduction of body weight, positive body feeling, vitality, enjoyment of life, and social contact. In the univariate analysis, orthopaedical patients scored higher on balneophysical treatments and vocational counselling (process expectations) as well as reduction of complaints and ability for work (outcome expectations). However, there were effects of age, gender and working status, too. Thus these differences between diagnostic groups turned out to be nonsignificant after controlling for the effects of age, gender, and working status. On the other hand, some effects of the medical condition had been hidden in the univariate comparison and were only revealed when adjusting for the moderator variables. Those differences show that oncological patients had higher expectations than back pain patients. Patients' expectations were correlated with functional status and, to a lesser degree, emotional distress and locus of control. To conclude, our study demonstrated that medical condition, sociodemographic factors, working status and functional capacity are important determinants of patient expectations regarding the process and outcome of rehabilitation.
