RESUMO
OBJECTIVES: This study examined whether 'personality vulnerability' (i.e., self-critical perfectionism or dependency) predicts the trajectory of change, as well as variability and instability (i.e., entropy) of symptoms, during cognitive behaviour therapy (CBT) for depression. DESIGN: Study participants were outpatients (N = 312) experiencing a primary mood disorder. Participants received CBT for depression group sessions over 15 weeks. Self-report measures of self-critical perfectionism, dependency, and depression were collected longitudinally. METHODS: A latent growth mixture modelling (LGMM) statistical approach was used to evaluate the presence of latent classes of individuals based on their longitudinal pattern of symptom change during CBT and to evaluate whether baseline self-critical perfectionism or dependency predicts class membership. A Latent Acceleration Score (LAS) model evaluated whether perfectionism or dependency led to variability in depression symptom change (e.g., velocity) by considering changes in velocity (e.g., acceleration and/or deceleration). RESULTS: LGMM indicated the presence of two latent classes that represent symptom improvement (N = 239) or minimal symptom improvement over time (N = 73). Elevated baseline self-critical perfectionism, but not dependency, predicted a greater likelihood of membership in the class of participants who demonstrated minimal symptom improvement over time. The second analysis examined whether baseline self-critical perfectionism also predicts depression symptom variability and instability. The LAS perfectionism model demonstrated that perfectionism accelerates depression symptom change during the first seven sessions of treatment, then has a decelerating effect on depression symptom change. CONCLUSIONS: Results indicated that higher baseline self-critical perfectionism predicted higher variability and instability in depression symptoms and variability in acceleration and deceleration, over the course of treatment.

Early intervention for psychosis has become an established clinical practice. Research is now focusing on identifying individuals in the pre-psychotic period when they appear to be putatively prodromal for psychosis. Criteria have been established for identifying these young people who are at clinical high risk, and there have been some early studies testing both pharmacological and psychological treatments. Cognitive behavioral therapy (CBT) has been tested as a potentially effective intervention in this group. Here, we describe two cases that were treated with CBT.

OBJECTIVE: Both Mindfulness Based Cognitive Therapy (MBCT) and Cognitive Therapy (CT) enhance self-management of prodromal symptoms associated with depressive relapse, albeit through divergent therapeutic procedures. We evaluated rates of relapse in remitted depressed patients receiving MBCT and CT. Decentering and dysfunctional attitudes were assessed as treatment-specific process markers. METHOD: Participants in remission from Major Depressive Disorder (MDD; N = 166) were randomized to 8 weeks of either MBCT (N = 82) or CT (N = 84) and were followed for 24 months, with process markers measured every 3 months. Attendance in both treatments was high (6.3/8 session) and treatment fidelity and competence were evaluated. Relapse was defined as a return of symptoms meeting the criteria for major depression on Module A of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (SCID). RESULTS: Intention-to-treat analyses indicated no differences between MBCT and CT in either rates of relapse to MDD or time to relapse across 24 months of follow up. Both groups experienced significant increases in decentering and participants in CT reported greater reductions in dysfunctional attitudes. Within both treatments, participants who relapsed evidenced lower decentering scores than those who stayed well over the follow up. CONCLUSIONS: This is the first study to directly compare relapse prophylaxis following MBCT and CT directly. The lack of group differences in time to relapse supports the view that both interventions are equally effective and that increases in decentering achieved via either treatment are associated with greater protection. These findings lend credence to Teasdale et al.'s (2002) contention that, even though they may be taught through dissimilar methods, CT and MBCT help participants develop similar metacognitive skills for the regulation of distressing thoughts and emotions.

Barlow et al. published the unified protocol (UP) for transdiagnostic treatment of emotional disorders, focusing on common pathological factors across a variety of diagnoses. The limited UP research to date suggests that this treatment may be particularly useful for anxiety disorders. However, it has largely been evaluated only in individual treatment format. The current study examined the effectiveness of the UP treatment in a group format, with individuals with comorbid anxiety disorder symptoms. Twenty-six individuals with clinically significant anxiety symptoms in at least two of the following areas, social anxiety, worry, or panic, participated in a 14-week manualized group treatment using the UP. Significant decreases were found on general anxiety, worry, social anxiety, panic, depression, and negative affect, and increases on positive affect. The UP may hold promise for a transdiagnostic group treatment of comorbid anxiety symptoms, but further examination of this treatment is warranted.

Cognitive-behavioral therapy (CBT) for depression is highly effective. An essential element of this therapy involves acquiring and utilizing CBT skills; however, it is unclear whether the type of CBT skill used is associated with differential symptom alleviation. Outpatients (N = 356) diagnosed with a primary mood disorder received 14 two-hour group sessions of CBT for depression, using the Mind Over Mood protocol. In each session, patients completed the Beck Depression Inventory and throughout the week they reported on their use of CBT skills: behavioral activation (BA), cognitive restructuring (CR), and core belief (CB) strategies. Bivariate latent difference score (LDS) longitudinal analyses were used to examine patterns of differential skill use and subsequent symptom change, and multigroup LDS analyses were used to determine whether longitudinal associations differed as a function of initial depression severity. Higher levels of BA use were associated with a greater subsequent decrease in depressive symptoms for patients with mild to moderate initial depression symptoms relative to those with severe symptoms. Higher levels of CR use were associated with a greater subsequent decrease in depressive symptoms, whereas higher levels of CB use were followed by a subsequent increase in depressive symptoms, regardless of initial severity. Results indicated that the type of CBT skill used is associated with differential patterns of subsequent symptom change. BA use was associated with differential subsequent change as a function of initial severity (patients with less severe depression symptoms demonstrated greater symptom improvement), whereas CR use was associated with symptom alleviation and CB use with an increase in subsequent symptoms as related to initial severity.
