Participation in psychosocial group intervention among Japanese women with primary breast cancer and its associated factors.

Though psychosocial group intervention is considered in the West to be an important source of support for reducing psychosocial distress in cancer patients, in Asian countries, there has been no research as yet on the needs for such intervention. This study investigated the level of participation and interest in psychosocial group intervention plus any associated factors in 151 primary breast cancer patients. All were less than 65 years old at 4-18 months post-surgery. Of the 126 subjects who responded (response rate 83%), 53 (42%) participated (participants) and 73 (58%) did not (non-participants). Participation was greater among those with a high level of anxiety measured by the Hospital Anxiety and Depression Scale (HADS) (odds ratio [OR], 3.25; 95% confidence interval [CI], 1.07-10.42), those who had undergone surgery within the last 12 months (OR, 3.10; 95% CI, 1.35-7.55), and those who were 50-65 years old (OR, 3.08; 95% CI, 1.33-7.66). Among the non-participants, 53 (73%) were interested in the intervention while 20 (27%) were not. Non-participants without any interest in the psychosocial group intervention had significantly higher anxiety levels than those with interest (t=-2.08; df=71; p=0.03). These results suggest that most Japanese breast cancer patients who need psychological support can be sought out by asking whether they are willing to participate in a psychosocial group intervention. However, the minority not interested in any psychological group intervention might need other supports such as medication or individual psychotherapy. Copyright 2001 John Wiley & Sons, Ltd.
