Abstract

Background: Although many risk factors have been proposed for the etiology of the addiction, little research has been conducted from the perspective of evolutionary psychology. The theory of life strategies (with respect to evolutionary causes) has led to a new understanding of addiction. While researchers have shown that Cloninger's bio-psychological model is one of the most important personality factors in the etiology of addiction, there is no research about the relationship between life strategy and the temperament-character component of addiction. Objectives: The main objective of this study was to examine the relationship between these two variables in individuals with opioid use disorder in comparison with the normal group. Patients and Methods: This correlational study included 96 participants with opioid use disorder selected by convenience sampling from the Iranian national center for addiction studies (INCAS) and 97 participants without any substance use disorder, who were matched to the opioid-use group. After administering the mini-form of Arizona life history battery (ALHB) and the temperament and character inventory (TCI), data were analyzed with Pearson's correlation coefficient and multivariate regression. Results: Results showed a relationship between fast-life strategy and novelty seeking in the group with opioid use disorder and a positive relationship between slow-life strategy and co-operation in the control group. The regression analysis indicated that novelty seeking was able to predict fast-life strategy in the opioid use group and co-operation could predict slow-life strategy in the control group. Conclusions: Life strategy could be a new variable in understanding and planning addiction prevention programs. © 2018, International Journal of High Risk Behaviors and Addiction.
