Aim: The aim was to investigate whether high catecholamine (CA) excreters would respond less well to a group cognitive behaviour therapy (CBT) treatment for depression than others. Method: A sample of 70 adults with depression symptoms participated in a 12-week course of group CBT. Participants’ 24 hour urinary catecholamine levels at pre-therapy and post-therapy were used to classify them as High (N = 10); Low (N = 33) or Mixed (N = 27) according to a cut-off one standard deviation above a published mean for healthy adults. Beck Depression Inventory (BDI) and cognitions questionnaire (Automatic Thoughts Questionnaire; Beck Hopelessness Scale and Dysfunctional Attitudes Scale) were used. Results: Repeated measures ANOVA analyses showed an equal rate of mood improvement in all three groups over the course of CBT, despite the fact that the High excreters were on average more depressed throughout the study. Changes in depression symptoms were mirrored by improvements in cognitive measures in the three catecholamine groups. Conclusion: This study indicates that adults showing a biological marker of depression (elevated catecholamine levels) are equally able to benefit from CBT treatment as adults without this marker.

Background: The study aimed to assess the effectiveness of group and individual formats of a combined motivational interviewing and cognitive behavioral treatment (CBT) program for problem gamblers (PGs) using a randomized controlled design. Method: One hundred and two PGs were randomly assigned to individual or group CBT conditions. Twenty-eight of these participants were randomly allocated to a 6-week waitlist control condition prior to receiving the designated treatment. Results: At post-treatment, there were significant improvements in all dependent variables (frequency and amount gambled, gambling urges, gambling cognitions, negative psychological states, and life satisfaction) for both the treatment conditions but not for the waitlist condition. Individuals that completed the individual (compared to group) treatment condition generally had higher effect sizes for gambling correlates. Therapeutic gains for gambling correlates were generally maintained at 6-month follow-up. Conclusions: A combined motivational interviewing and CBT program applied in group or individual format can improve PG behaviors, as well as gambling correlates.

The present study sought to clarify the role of cognitive change in Cognitive Behavioural Therapy (CBT) by examining the relationship between depression outcome and changes to automatic thoughts and dysfunctional attitudes at different points of therapy. Thirty patients suffering from Major Depression (MDD) or Dysthymia attended the 12 sessions of a group CBT program. Multiple regressions found total scores on the Automatic Thoughts Questionnaire (ATQ) and cumulative change scores on the Dysfunctional Attitudes Scale (DAS) to predict scores on the Beck Depression Inventory (BDI) at later stages of therapy, though neither form of cognition was predictive from earlier stages of therapy. Only scores on the ATQ were significantly related to both cognitive and somatic subscales of the BDI, indicating that automatic thoughts are more directly related to cognitive change than dysfunctional attitudes. Overall findings suggest that significant reductions in both automatic thoughts and dysfunctional attitudes are related to non-clinical levels of depressive symptoms at the end of the treatment.

This study examined in detail the psychobiological correlates of panic attacks experienced in panic disorder with agoraphobia. The cognitions, affect, and physiology of the six patients were monitored during in vivo exposure to their phobic situations. The results from these case studies showed that catastrophic cognitions are the key component of panic attacks. However, there was no clear-cut evidence to support an interaction among cognitions, affect, and physiology, which has been postulated by cognitive theories to be the central component of panic attacks and panic disorder with agoraphobia.

The present paper aimed (1) to review the literature to examine the effectiveness of CBT as treatment for PDA and (2) to evaluate whether the efficacy of CBT treatments is related to the change to cognitive processes that are postulated to be important in the cognitive models of PDA. A literature review of CBT studies in the area of PDA was conducted using both descriptive and quantitative (meta-analysis) procedures. In all, 35 studies published between 1969 and 1996 were included. The results show that CBT is an effective treatment for PDA. However, the contribution of cognitive processes to this disorder and the role that they play in the successful outcome of CBT remain unclear and in need of further empirical investigation. At present, CBT treatment provides limited support to validate the cognitive models of PDA.

The present study used two single case studies to evaluate clinical improvement as a result of cognitive behavior therapy in panic disorder with or without agoraphobia (PDA). A special emphasis was placed on assessing the reduction in catastrophic cognitions, which are considered to be of prime importance in PDA. Multiple measures were employed, during pre and post treatment and at a six month follow-up. Data from self-report questionnaires, physiological measures and cognitive sampling during in vivo exposure were used. Convergent results demonstrated clinical improvement and supported the importance of catastrophic cognitions in the process of change for treatment outcome of PDA.

Research using ambulatory monitoring and cognitive sampling procedures has revealed the importance of negatively biased cognitions in panic attacks and panic disorder. However, the normal population has never been investigated on the basis of these procedures and it is still unclear how patients deviate from them on the basis of negative cognitions and their interaction with affect and physiology. The present study investigated these issues by comparing 15 panic disorder patients with an equal number of normal controls. The results revealed that, although the pattern of reporting cognitions was similar, the two groups differed on type and content of the cognitions. In general, there were significant differences between the two groups for neutral and negative cognitions. Patients experienced high anxiety levels that were associated with cognitions of negative affect. There was a low frequency of reported panic attacks in the patients group. Possible reasons for the limited number of panic attacks are discussed.

While Cognitive Behavior Therapy (CBT) has been widely used for treatment of childhood disorders, the process underlying the success of CBT in this area is still unclear. This paper attempts to examine empirically the above issue, using the literature from 1974 to 1989 to see whether there is support for the underlying changes in cognitive processes that are assumed to mediate the therapy. The results show that while CBT is relatively effective in treating some childhood disorders, there is little empirical evidence to support the underlying cognitive models of childhood disorders.

This paper critically evaluates the empirical evidence of 36 studies regarding the comparative cost-effectiveness of group and individual cognitive behaviour therapy (CBT) as a whole, and also for specific mental disorders (e.g. depression, anxiety, substance abuse) or populations (e.g. children). Methods of calculating costs, as well as methods of comparing treatment outcomes were appraised and criticized. Overall, the evidence that group CBT is more cost-effective than individual CBT is mixed, with group CBT appearing to be more cost effective in treating depression and children, but less cost effective in treating drugs and alcohol dependence, anxiety and social phobias. In addition, methodological weaknesses in the studies assessed are noted. There is a need to improve cost calculation methodology, as well as more solid and a greater number of empirical cost-effectiveness studies before a firm conclusion can be reached that group CBT is more cost effective then individual CBT.
