The Toronto Mindfulness Scale: development and validation.

In this study, the authors both developed and validated a self-report mindfulness measure, the Toronto Mindfulness Scale (TMS). In Study 1, participants were individuals with and without meditation experience. Results showed good internal consistency and two factors, Curiosity and Decentering. Most of the expected relationships with other constructs were as expected. The TMS scores increased with increasing mindfulness meditation experience. In Study 2, criterion and incremental validity of the TMS were investigated on a group of individuals participating in 8-week mindfulness-based stress reduction programs. Results showed that TMS scores increased following treatment, and Decentering scores predicted improvements in clinical outcome. Thus, the TMS is a promising measure of the mindfulness state with good psychometric properties and predictive of treatment outcome.

Integrating mindfulness meditation with cognitive and behavioural therapies: the challenge of combining acceptance- and change-based strategies.

Recent innovations in psychological treatments have integrated mindfulness meditation techniques with traditional cognitive and behavioural therapies, challenging traditional cognitive and behavioural therapists to integrate acceptance- and change-based strategies. This article details how 2 treatments, mindfulness-based cognitive therapy and dialectical behaviour therapy, have met this challenge. We review the integration rationale underlying the 2 treatments, how the treatments combine strategies from each modality to accomplish treatment goals, implications for therapist training, and treatment effectiveness. In addition, we discuss the challenges of assessing the benefits of incorporating acceptance-based strategies. Both therapies have integrated acceptance-based mindfulness approaches with change-based cognitive and behavioural therapies to create efficacious treatments.

Teasdale's differential activation hypothesis: implications for mechanisms of depressive relapse and suicidal behaviour.

Teasdale's differential activation hypothesis (DAH) has been proposed as one account of cognitive vulnerability to depression. This view holds that important factors determining whether one's initial depression becomes more severe or persistent are the degree of activation, and content, of negative thinking patterns that become accessible in the depressed state. This phenomenon has been referred to as cognitive reactivity. Empirical support for the predictions of this model derives from a combination of cross-sectional and prospective studies. In this article, we evaluate this evidence with the goal of determining whether mood-induced cognitive reactivity can be considered a risk factor for depressive relapse/recurrence. Our review demonstrates sufficient evidence to consider cognitive reactivity as a potential causal risk factor for depressive relapse/recurrence. Furthermore, we extend the application of this model to the problem of suicidal relapse/recurrence including a review of preliminary support for this approach.

Design and feasibility of a new cognitive-behavioural therapy course using a longitudinal interactive format.

OBJECTIVE: This report describes the design and feasibility of conducting a unique longitudinal supervision course incorporating both therapist and patient evaluation measures in teaching cognitive-behavioural therapy (CBT) to a group of mental health practitioners. METHOD: We designed a 10-session longitudinal supervision course to teach CBT by applying key continuing medical education (CME) principles. Each session consisted of 30 minutes of didactics and demonstrations followed by 90 minutes of group case supervision. Course participants were mental health practitioners who treated patients from their own practice; most of the patients suffered from a depressive and (or) anxiety disorder. We assessed therapists for CBT skill acquisition at the beginning and at the end of the course, using the Cognitive Therapy Scale (CTS). We assessed patients' symptoms weekly, using the Beck Depression Inventory, the Beck Anxiety Inventory, and the Clinical Global Impression scale. RESULTS: A total of 34 participants enrolled in three 10-session courses. Most participants submitted audiotapes for rating at the beginning and end of the course, and most submitted patient symptom information. CONCLUSIONS: This course shows promise as an effective way to teach complex skills in CBT to mental health providers. In limited samples, the course showed clear improvement in therapist adherence to CBT and in patients' clinical outcomes. Future research is required to validate the potential benefit of this CME intervention for mental health practitioners treating patients with mood and anxiety disorders.
