By means of a single case study, the effects of redirecting attention above exposure only on fear of blushing, avoidance, and idiosyncratic dysfunctional beliefs were tested. A social phobic patient with fear of blushing as the predominant complaint received sessions of Task Concentration Training (TCT) and Exposure in Vivo (EXP) alternately, after a steady baseline had been established. The treatment consisted of 14 individual sessions. Assessments were held before and after baseline, after treatment, after 4 weeks follow-up, and after 1-year follow-up. Continuous measurements were held throughout the treatment in order to measure the differential effects of TCT and EXP on fear, avoidance and beliefs. TCT and EXP together, turned out to be an effective treatment for fear of blushing: large effects were observed on all three outcome measurements. When differential effects are closely looked at, EXP seemed more effective in decreasing fear of blushing. However, the patient appeared to have used TCT strategies as well during the EXP weeks, which may have contributed to the favourable effects of EXP.

The present study examined whether trait anxiety as indexed by the Spielberger State-Trait Anxiety Inventory (STAI) can be employed as a predictor of behaviour therapy outcome. Thirty-six female spider phobic patients completed the STAI trait anxiety scale, and then received one 2.5 hours session of exposure in vivo treatment. Therapy outcome was evaluated by means of standardized self-report measures and a behavioural approach test. Results showed that STAI trait anxiety substantially contributed to therapy success on all outcome measures: the higher the trait anxiety scores, the less patients profited from behaviour therapy.
