Mindfulness-based Cognitive Therapy for Generalized Anxiety Disorder: A Preliminary Evaluation

Mindfulness training has been proposed as a potentially important new approach for the treatment of generalized anxiety disorder (GAD). However, to date only a few studies have investigated mindfulness training for GAD. The aim of this study was to further investigate symptom change and recovery in pathological worry after mindfulness-based cognitive therapy (MBCT) using an uncontrolled pre-post design. Twenty-three adults with a primary diagnosis of GAD participated in the study. The MBCT program involved 9 weekly 2-hour group sessions, a post-treatment assessment session, and 6-week and 3-month follow-up sessions. Intent-to-treat analysis revealed significant improvements in pathological worry, stress, quality of life, and a number of other symptoms at post-treatment, which were maintained at follow-up. Attrition was also low, and MBCT was perceived as a credible and acceptable intervention. However, when applying standardized recovery criteria to pathological worry scores, the rate of recovery at post-treatment was very small, although improved at follow-up. Overall, the findings suggest MBCT is definitely worthy of further investigation as a treatment option for GAD, but falls well short of outcomes achieved by past research. Possible reasons for the poor rate of recovery, implications, and limitations are briefly outlined.

The Purpose in Life Scale: Psychometric Properties for Social Drinkers and Drinkers in Alcohol Treatment

The aim of the present research was to further investigate (a) the structure of the Purpose in Life test (PIL) using confirmatory factor analytic techniques,(b) the reliability of PIL scores, and (c) the validity of the PIL. Participants were 357 social drinkers (not in alcohol treatment) and 137 treatment drinkers (in alcohol treatment). With the exclusion of 3 items, a unidimensional measurement model for the PIL provided an adequate fit for social and treatment drinkers. Model invariance analysis indicated that 6 of 17 PIL items had different pattern coefficients for the two groups of drinkers. The 17 items of the PIL demonstrated good measurement reliability for both groups of drinkers and good criterion-related validity

Post-traumatic growth and bereavement

Abstract There is no uniform response to death, and the range of initial responses may run from delighted, satisfied and relieved, through to distraught, depressed and traumatised. This variability in initial response means that the subsequent course of bereavement is likely to be equally varied – with final outcomes often dependent upon what has preceded them. Where some subset of final outcomes is of research interest, it is essential that the antecedents of, or preconditions for, the final outcome are of at least equal interest. This appears in some cases to have become less of a focus in the bereavement research on post-traumatic growth (PTG). Without at least attempting to distinguish normal mourning from depression, and traumatic from other pathological responses to bereavement, it is unlikely that PTG will be consistently associated with adjustment or distress. In this review, we outline some of the conceptual distinctions that may be important in increasing our understanding of responses to death and conclude that making such distinctions, where possible, can enhance our treatment approaches in terms of ensuring they are tailored to accommodate particular psychiatric syndrome(s) that can follow bereavement, but are also aimed at facilitating PTG in certain individuals.

Psychometric Properties of the Locus of Control of Behaviour Scale (LCBS) among Australians Seeking Alcohol and Other Drug (AOD) Treatment

Despite a paucity of studies evaluating the psychometric properties of the Locus of Control of Behaviour Scale (LCBS), it continues to be widely used in behavioural research. The present study sought to redress this gap in the literature. The 17‐item LCBS was administered to 373 Australians attending Alcohol and Other Drug (AOD) treatment agencies in the northern metropolitan region of Perth. Confirmatory factor analyses were conducted in order to determine which of several plausible measurement models provided the best fit for the data. A unidimensional model, recommended by the authors of the LCBS, and a two‐dimensional (Internal Locus of Control vs External Locus of Control) model provided poor fits. Other multidimensional models, differing only in the dimensionality of the externality factor, were also tested. A multidimensional model consisting of an Internal Locus of Control factor and four component External Locus of Control factors provided the best fit; however, the fit is probably best described as “reasonable” rather than “good.” A subsequent exploratory factor analysis using parallel analysis indicated a cohesive internality factor; however, the externality factor showed a tendency to fragment into smaller components. Results were discussed in terms of the problematic externality factor.
