objectives: the present study aimed at examining the relationship between the enneagram personality types and health responsibility in patients with substance use disorder (sud). methods: the current cross sectional study was conducted on 68 patients with sud referred to methadone maintenance treatment clinics in kermanshah city, western iran, in september 2017. the riso-hudson enneagram type indicator (rheti) and subscale of health responsibility from the health promoting lifestyle profile (hplp-ii) were used for data gathering. the obtained data were analyzed using pearson correlation and multiple linear regression analysis. results: the mean sd age of the samples (100% male) was 39.4 13.3 years. the obtained results showed a significant direct relationship between personality types 1 and 3 and health responsibility, while the same relationship was indirect for the personality type 4 (p < 0.05). despite the inability of the three personality types in predicting health responsibility, the model generally could explain 12.5% of the variance in criterion variable. conclusions: probably, screening the personality patterns of patients with sud using the enneagram model can be useful to identify vulnerable groups. since sud rehabilitation includes long-term formal nursing services, training should be focused on improved health responsibility among risk-taking personalities such as type 4.
