Objective? To understand the situation of disability acceptance, coping style and social support in rectal cancer patients with permanent enterostomy and to explore the correlations among them. Methods? From March 2017 to December 2017, we selected 110 rectal cancer patients with permanent enterostomy in Heilongjiang Provincial Hospital as subjects by convenience sampling. All of the patients were investigated with the Acceptance of Disability Scale (ADS), Simplified Coping Style Questionnaire (SCSQ), Social Support Rating Scale (SSRS). Results? A total of 110 questionnaires were sent out and 101 valid questionnaires were collected. The total score of ADS, the scores of positive coping and negative coping of SCSQ as well as the total score of SSRS, were (79.55±7.42), (1.69±0.37), (1.74±0.24) and (41.35±10.24) respectively among rectal cancer patients with permanent enterostomy. The total score of ADS was positively correlated with the positive coping (P＜0.05), was negatively correlated with the negative coping (P＜0.05), and it also had a positive correlation with the total score of SSRS (P＜ 0.05). Conclusions? The disability acceptance of rectal cancer patients with permanent enterostomy needs to be improved. Health care providers should take targeted intervention based on social support system so as to help patients take positive coping style to improve their disability acceptance.
