Participant, MM, exhibits the nonfunctional behavior of excessive cigarette smoking. This behavior began in late adolescence through social learning. The targeted behavior occurred mainly when MM was alone at home, on her balcony, and occasionally when she was away from home, with friends who also smoked, at night. Using the laptop, studying, drinking beverages, and experiencing feelings of boredom or stress acted as triggers for MM to elicit this behavior. MM lacked a consistent sleep routine and was prone to fatigue. Thus, the subject sometimes drank coffee to compensate and was often stressed. The subject was at university, which required him to spend a lot of time studying, which led to additional stress. MM's smoking was positively reinforced by small increases in his concentration and feelings of confidence in social situations. The behavior was negatively reinforced by small reductions in his stress levels and feelings of boredom and by dampening his cravings. The behavior was positively punished by negative comments made by others about the smell of cigarette smoke, by MM's feelings of embarrassment about his behavior, and by the resulting increased susceptibility to chronic illness. . His smoking was also penalized by his reduced finances, impaired cardiovascular fitness, and likely shortened lifespan. DiscussionThe aim of this case study was to complete a functional analysis of MM's smoking behavior, in order to develop an individualized behavioral intervention. The most salient points of the SORCK were firstly that the context in which MM was alone, at home and on her balcony increased the likelihood...... middle of paper ...... this treatment plan would only work if MM was committed to it. Restriction to generally available reinforcers, maintaining the star chart, and implementing aversive elements, may become too rigorous for MM. Thus, this may reduce their compliance with the intervention. A limitation of this study in terms of self-monitoring This period was the reactivity of self-observation. There were odd occasions during the self-monitoring period, where MM found herself refraining from smoking another cigarette because she felt the current total for the day was already too high . Therefore, the results cannot be considered a completely accurate account of the frequency of MM smoking behavior. Despite these limitations, this study demonstrated how a specific intervention for smoking behavior in MM could be achieved through a functional analysis..
