Addiction is a psychological and behavioral syndrome which is associated with a strong desire to use drugs (
1). Some people who use drugs and have entered to addiction’s process are attempting to quit or control drug abuse, when they become aware of its negative side effects. But a small number of them who have stopped their drug abuse, can not fully observe their abstinence and will relapse again (
2). Addiction is a multi dimensional disease and is often associated with many problems such as frequent relapse (
3). Drug abuse is known as a chronic, long term relapsing process. Unfortunately, little attention has been paid to this issue up to now (
4).
Marlatt and Gordon have estimated the likelihood of return to drug abuse to be about 50 percent by the most optimistic estimation. According to them, this probability varies from 60 to 90 % (
5). In Iran, fifty percent of recovered addicts have a tendency to resume drug abuse (
6). The relapse concept has changed over the years and it is now as a failure in person’s recovery. As Dennis et al have noted, relapse is the result of previous unhealthy actions that predisposes the person to relapse. Normally, people who relapse show signs of change in their attitudes, thoughts, feelings and actions (
7). In a study conducted in Iran, 80% of addicts relapsed at the first 6 months (
8).
Several models have been proposed for relapse, but the most comprehensive is the cognitive behavioral approach (
4, 5). In this regard, the concept of “high risk situations” has emerged and two main categories of high-risk situations were identified: intrapersonal factors including negative emotions (NE) , physical discomfort (PD) , urge and temptation (UT), positive emotions (PE), test of personal control (TPC) and, interpersonal factors, including conflict with others (CO), social pressure (SP), pressure times (PT) (
5). Relapse prevention is a medical intervention designed for educating cognitive and behavioral skills to avoid relapse. Marllat's relapse prevention (RP) model was developed after over twenty years of his research and is updated continually based on empirical findings (
9). Although other relapse models exist, valid results have been achieved using this model in well-designed and well- controlled studies. This model is based on a number of high-risk situations that can make people aware of the potential for relapse. The high-risk situations include people, places, feelings and thoughts which can lead to relapse. In addition, there are numerous factors aside from these high-risk situations such as destructive thinking patterns, unbalanced lifestyle and lack of planning. These combined factors undermines individuals’ decisions even before encountering the situation (
5). The more risk factors a person has, the higher is the likelihood of drug abuse (
10). The RP model includes specific intervention strategies which allow the therapist and the client to examine each step of the relapse process. This intervention includes identifying specific high-risk situations and coping skills to deal with the situation, increasing self efficacy, handling relapse, and reconstructing clients’ perceptions of the relapse process and therefore reducing the risk of relapse (
6).
In recent years, the relapse prevention model is widely used throughout the world. Marlatt and Gordon in a study about highest risk situations for relapse among the youth indicated that interpersonal and intrapersonal factors compromised 58% and 42% of the original sample, respectively. Unpleasant emotions were the most frequently reported high risk situation (37%) (
5). El, Sheikh investigated some relapse related situations in alcoholics and heroin addicts. They found that physical discomfort, social pressure and pleasant times with others situations, had the high mean scores in both groups (
9). In Hartwell’s study performed among opiate addicts, the highest mean scores were related to physical discomfort, conflicts with others and testing the personal control (
11). In another study from Iran, the most prevalent reason of relapse was unpleasant emotions and spending pleasant times with others (
12). Despite extensive studies in our country, we could not find any study that had extensively evaluated high- risk situations for relapse.
