The clinical effectiveness of cognitive behaviour therapy: outcome for a large sample of adults treated in routine practice

There is increasing interest in questions about how far the demonstrated efficacy of psychological therapies in research trials can be translated into clinical effectiveness in routine practice. This paper summarises outcome data from several hundred patients treated with CBT in routine clinical practice in a National Health Service psychology service, and compares their outcomes with some of the published research. Although the data have flaws common in ordinary clinical practice (no untreated controls, missing data, uncontrolled pharmacotherapy, etc.), the analyses suggest that CBT in this context is an effective treatment, albeit with probably not quite such good results as it achieves in research trials. Using clinical significance statistics on standardised measures, about half of the sample reliably improved over a course of therapy, including about a third who recovered to normal range.     

Cognitive therapy versus interoceptive exposure as treatment of panic disorder without agoraphobia

Cognitive therapy (CT) and interoceptive exposure (IE) as treatments of panic disorder without agoraphobia were compared in a sample of 69 patients, randomly allocated to condition. There were no significant differences between treatments as to reductions in panic frequency, daily anxiety levels and a composite questionnaire score, at posttest after the 12-session treatment, and at both follow-ups (4 weeks, 6 months). In both conditions, high percentages of patients were panic free at post and follow-up tests (range 75-92%). Although the reduction in idiosyncratic beliefs about the catastrophic nature of bodily sensations was equally strong in both conditions, post-treatment beliefs correlated strongly with symptoms at post and follow-up tests in the CT condition, but not in the IE condition. Reduction of beliefs may be essential in CT, but not in IE. This suggests that the two treatments utilize different change mechanisms.     

Virtual reality treatment versus exposure in vivo: a comparative evaluation in acrophobia

The aim of the present study was to evaluate the effectiveness of low-budget virtual reality (VR) exposure versus exposure in vivo in a between-group design in 33 patients suffering from acrophobia. The virtual environments used in treatment were exactly copied from the real environments used in the exposure in vivo program. VR exposure was found to be as effective as exposure in vivo on anxiety and avoidance as measured with the Acrophobia Questionnaire (AQ), the Attitude Towards Heights Questionnaire (ATHQ) and the Behavioral Avoidance Test (BAT). Results were maintained up to six months follow-up. The present study shows that VR exposure can be effective with relatively cheap hardware and software on stand-alone computers currently on the market. Further studies into the effectiveness of VR exposure are recommended in other clinical groups as agoraphobics and social phobics and studies in which VR exposure is compared with more emerging virtual worlds as presented in CAVE-type systems.     

心理咨询过程-效果研究现状及展望

心理咨询过程-效果研究考察咨询过程变量对咨询效果的影响。以人为中心流派、认知流派、行为流派、精神分析流派等都为该研究领域提供了理论基础。主要研究内容有咨询师的反应方式、会谈中的当事人行为、工作同盟、会谈中的重要内容等过程变量与效果的关系。该领域积累的成果还不多,这可能与过程-效果关系本身的复杂性有关,同时研究方法尚有许多欠缺,如考察复杂关系时使用的研究设计过于简单、测量工具不统一导致结果难以比较,有些测量工具不成熟信效度不高。未来的研究除了努力克服这些问题外,还应多考虑理论构建、内隐变量的调节和中介作用、当事人变量,在研究方法上应更为综合和多样化     

Measure and integral with purely ordinal scales

We develop a purely ordinal model for aggregation functionals for lattice-valued functions, comprising as special cases quantiles, the Ky Fan metric and the Sugeno integral. For modelling findings of psychological experiments like the reflection effect in decision behaviour under risk or uncertainty, we introduce reflection lattices. These are complete linear lattices endowed with an order reversing bijection like the reflection at 0 on the real interval [−1,1]. Mathematically we investigate the lattice of nonvoid intervals in a complete linear lattice, then the class of monotone interval-valued functions and their inner product.     

论老子首倡人性善

老子是第一个提出人性善的哲学家。从他的宇宙生成论、人性修养论可以看出老子是主张人性善的。老子认为人性变坏的原因主要是客观事物的影响和世俗教育,"复归于婴儿"是老子人性修养论的总纲,其复归美好天性的主要措施是:反对享乐品的出现,反对世俗的教育。     

The impact of dissociation and depression on the efficacy of prolonged exposure treatment for PTSD

This study investigates the impact of dissociative phenomena and depression on the efficacy of prolonged exposure treatment in 71 patients with posttraumatic stress disorder (PTSD). Diagnoses, comorbidity, pretreatment depressive symptoms, PTSD symptom severity, and dissociative phenomena (trait dissociation, numbing, and depersonalization) were assessed at pretreatment using semi-structured interviews and questionnaires. In a pretreatment behavioral exposure test, patients were imaginally exposed to (part of) their trauma memory for 9 min, during which subjective fear was assessed. At posttreatment and 6 months follow-up PTSD, depressive and dissociative symptoms were again assessed in the completers (n = 60). Pretreatment levels of dissociative and depressive symptoms were similar in dropouts and completers and none of the dissociative phenomena nor depression predicted improvement. Against expectations, dissociative phenomena and depression were associated with enhanced rather than impeded fear activation during the behavioral exposure test. However, these effects disappeared after controlling for initial PTSD severity. Hence, rather than supporting contraindication, the current results imply that patients presenting with even severe dissociative or depressive symptoms may profit similarly from exposure treatment as do patients with minimal dissociative or depressive symptoms.     

L’adaptation transculturelle d’une échelle de mesure Cas de l’échelle des ancres de carrière

The objective of this research is to achieve a transcultural adaptation of a measure scale of professional values, particularly Schein’s (1985) career anchors from a north American context where it has been conceived to an arab-islamic culture, Tunisian’s environment. For this, this research follows a rigorous methodological process, that enable it to establish a new measure scale, offering good psychometric qualities and building up professional values adapted to Tunisian employees.     

The Relationship Between Dropout and Outcome in Naturalistic Cognitive Behavior Therapy

Dropout from psychotherapy is frequent and limits the benefits patients can receive from treatment. The study of factors associated with dropout has the potential to yield strategies to reduce it. This study analyzed data from a large sample of adults (N = 1,092) receiving naturalistic cognitive behavioral therapy (CBT) to test the hypotheses that dropouts, as compared to completers, had (1) higher symptom severity at treatment termination, (2) a slower rate of symptom change during treatment, and (3) a higher odds that the therapist rated treatment as ending for reasons related to poor outcome. Results showed that although dropouts ended treatment with higher symptom severity than completers, dropouts and completers did not differ in their rate of symptom change during treatment, suggesting that dropouts had higher symptom severity at termination because they received fewer sessions of treatment, not because their symptoms changed at a slower rate. Dropout was also associated with a higher odds of having a therapist-rated termination reason indicating a poor outcome, suggesting that dropout is more likely if patients are dissatisfied with some aspect of the therapy outcome or process. These findings suggest that strategies for monitoring and enhancing patient satisfaction with the process and outcome of treatment may help patients stay in treatment longer and end treatment with fewer symptoms than if they had dropped out.
