    ABSTRACT: The current study describes the validation of a new cognitive assessment measure for social phobia, entitled the Appraisal of Social Concerns (ASC). Item content is relevant to a range of social situations. The ASC can be used to tailor interventions to patients' idiosyncratic concerns. Data are presented from both clinical (n=71) and non-clinical (n=550) samples. Preliminary data indicate that the ASC has good internal consistency and test–retest reliability. The construct validity of the ASC is comparable to that of well-established measures in use with social phobics. A strength of the ASC is its sensitivity to the effect of treatment. An exploratory factor analysis yielded three factors tapping concerns about negative evaluation, observable symptoms, and social helplessness. Subscale scores were strongly correlated. Preliminary findings suggest that the ASC is a psychometrically sound, time efficient instrument that can be used for both clinical and research purposes.

    ABSTRACT: The present study examined the efficacy of an 8-wk, cognitive-behavioral group treatment for panic disorder. Patients meeting DSM-III-R criteria for panic disorder with or without agoraphobia were randomly assigned to treatment (N = 34) or delayed treatment control (N = 33). The treatment consisted of: (a) education and corrective information; (b) cognitive therapy; (c) training in diaphragmatic breathing; and (d) interoceptive exposure. At posttreatment, 85% of treated Ss were panic free, compared to 30% of controls. Treated Ss also showed clinically significant improvement on indices of anxiety, agoraphobia, depression and fear of fear. Recovery, as estimated conservatively by the attainment of normal levels of functioning on each of the major clinical dimensions of the disorder (i.e. panic, anxiety and avoidance), was achieved in 64% of the treated Ss and 9% of the controls. At the 6 month follow-up, 63% of the treated patients met criteria for recovery. These findings mirror those from recently-completed trials of individually-administered cognitive-behavioral treatment, and suggest that CBT is a viable alternative to pharmacotherapy in the treatment of panic disorder.
