Although the RP model considers the high-risk situation the immediate relapse trigger, it is actually the person’s response to the situation that determines whether he or she will experience a lapse (i.e., begin using alcohol). A person’s coping behavior in a high-risk situation is a particularly critical determinant of the likely outcome. Thus, a person who can execute effective coping strategies (e.g., a behavioral strategy, such as leaving the situation, or a cognitive strategy, such as positive self-talk) is less likely to relapse compared with a person lacking those skills. Moreover, people who have coped successfully with high-risk situations are assumed to experience a heightened sense of self-efficacy (i.e., a personal perception of mastery over the specific risky situation) (Bandura 1977; Marlatt et al. 1995, 1999; Marlatt and Gordon 1985). Conversely, people with low self-efficacy perceive themselves as lacking the motivation or ability to resist drinking in high-risk situations.
