Assignment 2 – Literature Review and Case study on CBT

Literature Review

Major Diagnosis: DSM-IV-TR (2000): Social Phobia (Social Anxiety Disorder).

According to the DSM-IV-TR (2000, p. 450) “The essential feature of Social Phobia is a marked and persistent fear of social or performance situations in which embarrassment may occur.” In a situation where the adolescent has social phobia, exposure to a social situation will provoke an immediate anxiety response, sweating, palpitations, and/or panic attack. Further to this the DSM-IV-TR (2000, p.450) also stipulates that a diagnosis of Social Phobia is “appropriate only if the avoidance, fear or anxious anticipation of encountering the social situation” interferes significantly with the person’s social or occupational functioning.  Symptoms must have persisted for at least six months, before diagnosis and the presentation cannot be better accounted for by other disorders.

  1. In order to confirm the psychopathology of adolescent social phobia, Beidel, Turner, Young, Ammerman, Floyd and Crosby(2007) carried out a clinical study on sixty-three adolescents with social phobia and compared them to a control group of forty three adolescents with no psychiatric disorders and established that while “clinically impairing social fear” was a common element for the group with social phobia, they also experienced “higher levels of loneliness, dysphoria, general emotional over-responsiveness and more internalizing behaviors than normal controls”, as well as being less socially skilled.  This is very relevant to my client Joe who isolates himself, is hyper vigilant of negative evaluation, has experienced anhedonia in the last year and feels socially inadequate to the point that he will have sweaty palms, goes pale when he thinks about interacting socially. Beidel, Turner, Young, Ammerman, Floyd and Crosby (2007) also found that 57.1% of socially phobic adolescents had a second, concurrent diagnosis, 75% of which were other anxiety disorders. This is also relevant to Joe who has another diagnosis of Cannabis Abuse while he also presents as very anxious around his physical health. The Strengths of the study is that it used randomised selection to allocate participants.  

  1. Velting and Albano (2001) examined the clinical presentation of Social phobia with particular attention to research carried out regarding the “developmental pathways of childhood social anxiety into social phobia, highlighting normative developmental factors, behavioural inhibition, pathophysiology, genetics, and parenting/environmental factors.” Joe’s personal history and background is telling with regards to confirming the role played by developmental factors in fuelling his social anxiety. In their findings Velting and Albano (2001) also came to the understanding that there is a critical need for effective treatments, for children and adolescents in order to ultimately circumvent the risk of long-term problems with education, employment, social relationships, and independent adult functioning.

  1. In a study to prove the effectiveness of CBT in treatment of social phobia, Spence, Donovan and Brechman-Toussaint(2000), enrolled fifty children between the ages of 7 to14 years with a principal diagnosis of social phobia and randomly assigned them to either child-focused cognitive-behaviour therapy (CBT), CBT plus parent involvement, or a wait list control (WLC). The integrated CBT program involved intensive social skills training combined with graded exposure and cognitive challenging. At post-treatment, significantly fewer children in the treatment conditions retained a clinical diagnosis of social phobia compared to the WLC condition.  In comparison to the WLC, children in both CBT interventions showed significantly greater reductions in children's social and general anxiety and a significant increase in parental ratings of child social skills performance. At 12-month follow-up, both treatment groups retained their improvement. There was a trend towards superior results when parents were involved in treatment, but this effect was not statistically significant. While Joe is a number of years older that this group, the results remain relevant for him given that teenagers formed part of the sample. The strengths of this study were that the sample was randomly assigned which generally reduces bias and the CBT interventions are applicable in usual practice.  A weakness may be the numbers studied given the possibility that the study may not be externally valid.

  1. Mancini, Van Ameringen, Bennett, Patterson and Watson (2005) sought to determine whether CBT would be equally effective in children and adolescents as has been proven in adults. Mancini et al (2005) saw value in the use of both CBT and Pharmacotherapy by way of treatment with SSRI’s and wondered if this might equally be effective in Adolescents. However Mancini et al (2005) acknowledge the lack of studies that have specifically looked at this comparison for youth, given that the comparison is usually between CBT intervention and a Waitlist control group. Mancini et al (2005) concluded that “Cognitive behavioural therapy is likely the treatment of choice for mild-to-moderate social phobia in youth. In more severe cases, clinicians should initiate treatment with an SSRI or SNRI. This is relevant to my client Joe with regards to current discussions around whether it might be appropriate to use an SSRI in conjunction with CBT in his treatment plan. Joe remains severely anxious and could possibly benefit from both treatments.

  1. Hawton, Salkovskis, Kirk and Clark (1998) examined the reasons why some anxious clients might have difficulty with identifying their negative thoughts. One reason put forward is that the negative thoughts are “so habitual and apparently plausible that they fail to attract the person’s attention. This has been my experience with the client under discussion. While there are some negative thoughts that he is able to rationalise and come to the realisation that he may be overestimating the perceived danger there are some thoughts such as the idea that when people are looking at him they are negatively evaluating him is so entrenched it may take a number of sessions to shift. Salkovskis et al (1989) advocate the use of discussion of a recent emotional experience, the use of imagery or role play to relive the emotional experience and others. I believe these two would work well with Joe given that he has an enquiring mind and would find both the discussion and the role play useful.
