An exploratory study of social problems experienced by ambulatory cancer patients in Japan: Frequency and association with perceived need for help.

Objective: Little is known about the social problems experienced by cancer patients in non-Western countries. The aims of this study were (1) to explore the characteristics and frequencies of social problems in cancer outpatients, as well as their associations with the need for help, and (2) to take the initial steps to develop an instrument for the assessment of cancer-related social problems in Japan.

Methods: A cross-sectional group of 109 patients completed the Social Problem Checklist and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30. Participants rated the levels of the problem severity and the need for help on each item. Factor structure, internal consistency, and construct validity were also assessed.

Results: In total, 72.5% of the participants encountered ≥1 problem, and 33% experienced ≥1 serious problem. The amount of help needed tended to be lower than problem severity, especially for family and social life issues. The most common reason for not needing help, as reported by approximately 40% of patients who experienced problems, was the preference for self-management. A 3-factor model was extracted that included financial matters, medical information, and family and social life. Excellent internal consistencies for each factor and convergent correlations between the relevant subscales of European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and Social Problem Checklist were confirmed.

Conclusions: A substantial proportion of participants had cancer-related social problems, but they had ambivalent help-related needs. Interventions that enhance the patient's abilities for self-care could be essential to help cancer outpatients manage social problems in Japan.
