The theme of this study is to investigate the effectiveness of hypnotherapy, as regards smoking cessation. An evaluation will be made regarding the effectiveness of single session therapy, compared to multiple session therapy. In light of this evaluation, a non-clinical case study will be discussed, in order to evaluate the benefits of adapting therapy to the needs of the individual. According to numerous studies, hypnotherapy for smoking cessation has produced impressive results. That said, the results are varied. Some studies claim impressive success, i.e. 90.6% (Barber, 2001), 90% (Klager, 2004) and 80% (Crasilneck, 1990), while others report lower success, i.e. 48% (Elkins and Rajab , 2004) and 25% (Ahijevych, Yerardi and Nedilsky, 2000). This variation may be due to the number of methods and approaches adopted (Crasilneck, 1990; Barber, 2001; Spiegel, Frischholz, Fleiss, & Spiegel, 1993). Or perhaps it could be due to the personality of the therapist, that is, the powerful “chemistry” of the alliance (Kroger, 1977; Lynn & Rue, 1991; Hubble, Duncun, & Miller, 1999). There are numerous variables when it comes to the smoking cessation study. However, the burden of this study is to focus on the constant variable, a variable common to all studies, i.e. the patient. First, however, it is important to explore whether single or multiple session therapy may prove more effective. There is strong evidence to support the use of multiple session hypnosis over single session hypnosis when it comes to smoking cessation (Hammond, 1990). Indeed, a variety of counseling methods have been found to be more effective in multiple sessions, regardless of technique (Zhu, Stretch, Balabanis, Rosbrook, Sadler, & Pierce, 1996). Furthermore, the meta-analysis delves further...... half of the paper...... patient (2) the family and social environment (3) the culture in which the patient lives and (4) the therapeutic intervention itself. It follows that (4) must be influenced by (1), (2) and (3). Therefore an appropriate treatment plan was considered based on this. D expressed that he is unhappy being a smoker. Additionally, he expressed concerns about his skin, his odor, the isolation, and the social stigma surrounding his smoking habit. D comes from a family of smokers and his father gave him his first cigarette when he was 12 years old. Social learning plays an obvious role in shaping self-perception and behavior (T. Barber, 1969, 2000; Spanos, 1991), and early experiences have a notable influence (Klein, 2008), which may be one of the reasons for the initial inability of D. termination. Furthermore, it may be D's secondary gain to "fit in" with his family.
