The Relationship Between the Enneagram Personality Types and Health Responsibility in Patients with Substance Use Disorder; A Brief Report

The present study aimed at examining the relationship between the Enneagram personality types and health responsibility in patients with substance use disorder (SUD). 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. 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. 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.
