Abstract

This research studied on the relationship between the type D personality and source control and predicting its addiction vulnerability. Its aim is to achieve a specific type personality and source control which can predict the addiction vulnerability. This study is descriptive and is done by correlation method to predict and investigate the relationship between the variables. Its statistical population included all active duty forces serving in a service unit. 50 persons were selected randomly. Data was collected by 3 questionnaires of identifying people who are at risk of addiction, type D personality and Rotter’s locus of control.The first questionnaire designed by Anisi (1392) includes 4 subscales of depression and helplessness, positive attitude to drugs, anxiety and fear and high sensation seeking. Type D personality questionnaire was designed by Denowelt in 1998 to measure the characteristics associated with type D personality. The third questionnaire was provided to assess the individual’s generalized expectations of internal control and external reinforcement. This study’s results showed that (i) there is a significant relationship between depression and sensation seeking and negative sentiment and also between positive attitude to drugs and sensation seeking; (ii) there is a negative relationship between the positive attitude to drugs and internal locus of control and also between anxiety and fear and sensation seeking and internal locus of control; and also (iii) there is a positive and significant relationship between addiction vulnerability and type D personality. Also, according to the regression analysis, addiction vulnerability of person can be predicted by type D personality. There is an inverse relationship between the locus of control and addiction vulnerability. Given to the relationship between the personality types and also external locus of control with addiction vulnerability, people can be foster to the internal locus of control by necessary training on necessary skills of people and also probability of the increase of people’s addiction vulnerability can be increased by developing a healthy personality type.
