Two hundred patients (200) from two complementary hospitals, one focusing on Traditional Chinese Medicine and one on the Western type of complementary medicine, completed an extensive questionnaire at the beginning of their inpatient treatment. The questionnaire covered personal background; disease parameters; attitude towards conventional medicine; previous experience with, and knowledge of, complementary therapies; expectations concerning the forthcoming treatment; health-related habits; personality traits; and social support.

Optimistic attitudes towards treatment and a positive appraisal of alternative doctors were frequently stated reasons (80%), as was the disease severity (long duration: 86%; acute progression or imminent surgery: 70%). Previous successes with complementary therapies, however, ranked relatively low (53%). Negative opinions concerning conventional therapies and conventional doctors' treatments were mentioned by 68% of the patients. Many patients felt themselves to be under considerable psychologic stress (74%). A majority (73%) was well informed about complementary therapies, and 65% were curious about the forthcoming therapies. Sixty-eight percent (68%) indicated good health behaviours. Fewer patients mentioned contemplative and/or religious attitudes (44%) or lack of social support (25%). Age primarily accounted for variations in the ranking weights of the two subgroups. The specific type of complementary medicine was of minor influence. In 14 out of 21 personality dimensions, the current patient group showed significant deviations from the healthy reference, which is in good agreement with findings from conventionally treated patients.
