Objective
Although it is important to analyze the effectiveness of new therapies, it is also necessary to consider how patients experience them. This is particularly important if we are to maximize treatment acceptability and reduce attrition. This study examined patient experiences of a new 10‐session cognitive‐behavioral therapy (CBT‐T), using a qualitative approach.
Method
The sample was 17 patients with a diagnosis of bulimia nervosa who had received CBT‐T (including treatment completers and non‐completers) within the previous 2 years. Sample size was determined by saturation of the emergent themes. Responses were analyzed using a six‐step thematic analysis process.
Results
Rated acceptability and effectiveness of CBT‐T were high. Five themes emerged, with subthemes. The key elements of patient experience of the therapy were: the therapeutic relationship; the nature of the therapy; its challenging but beneficial aspects; ending therapy; and the overall experience of CBT‐T (including comparison with other therapies).
Discussion
The findings build on the effectiveness research for CBT‐T, suggesting that it is an acceptable therapy that addresses many of the same themes that matter to patients as other therapies. The findings show that patients were positive about CBT‐T relative to other therapies, and offer suggestions as to how CBT‐T might be delivered to emphasize the importance of the time‐limited nature of the therapy.
We present a method for assessing an atomic force microscope's (AFM's) ability to reject externally applied vibrations. This method is demonstrated on one commercial and two prototype AFMs. For optimally functioning AFMs, we find that the response to externally applied vibrations obeys a 1/ω 2 frequency dependence. This 1/ω 2 frequency dependence can be understood by modelling the mechanical system which connects the AFM cantilever and the sample under test as a simple harmonic oscillator. According to such a model, the resonant frequency of the mechanical system which connects the AFM cantilever and the sample under test determines an AFM's ability to reject externally applied, low-frequency vibrations.
Objective
While there is evidence to support the use of group dialectical behavior therapy (DBT) in the treatment of binge‐eating disorder (BED), treatment is relatively long compared with other evidence‐based treatments. This study explored the effectiveness of brief DBT groups for BED, delivered in a routine community setting.
Method
Eighty‐four adults with BED entered 10‐week DBT group treatment in a community eating disorders service. In total, 12 groups were conducted. Patients completed measures of eating disorder pathology, anxiety, depression, and emotional eating at the start and end of treatment, and at 1‐month follow‐up. Frequency of weekly binges was recorded.
Results
Outcomes were similar to those of longer versions of DBT, with an attrition rate of 26%, and significant reductions in eating disorder psychopathology and emotional eating by the end of treatment and at follow‐up. Over 50% of patients were abstinent from binge eating by Session 4.
Discussion
Group DBT delivered in a 10‐session format is clinically equivalent to longer versions of the same treatment. Future research is required to explore patterns of change and to demonstrate replicability under controlled conditions, but these findings are promising for the efficient delivery of effective treatment and reducing waiting times.
