ABSTRACT Generalized anxiety disorder (GAD) is characterized by excessive worry and somatic symptoms of anxiety (e.g., restlessness, muscle tension). Several psychological treatments lead to significant reductions in GAD symptoms by posttreatment. However, little is known about how GAD symptoms change over time. Our main goal was to examine how GAD symptoms changed in relation to one another during 2 distinct but efficacious psychological treatments: cognitive-behavioral therapy (CBT) and applied relaxation (AR). Specifically, we asked whether change in worry accounted for change over time in somatic anxiety (or the reverse) to the same degree in CBT and AR.
We examined data from 57 individuals with GAD enrolled in a randomized controlled trial. Self-report measures of worry and somatic anxiety were obtained daily during treatment.
Although the direction of influence between changes in worry and somatic anxiety was bidirectional to some extent in both treatments, a significant difference was also observed: Change in worry accounted for subsequent change in somatic anxiety to a greater extent in CBT than in AR.
These findings allowed us to identify differences in a mechanism of change in GAD symptoms during 2 treatments and to provide some support for the idea that similarly efficacious treatments may produce symptom change via different mechanisms in a manner that is consistent with the theoretical rationales on which the treatments are based.

    • "Hence, it would be important to determine what happens specifi cally in the case of ADs and whether the presence of some specifi c technique can be associated with an increase of therapy duration. Among the techniques with greater empirical support of effi cacy and effectiveness most frequently used, are the techniques of psychoeducation, exposure, cognitive restructuring, or relaxation techniques (Donegan & Dugas, 2012; Hoyer, Beesdo, Gloster, Runge, Höfl er, & Becker, 2009; Öst, Svensson, Hellström, & Lindwall, 2001). Therefore, it is important to study the value of these techniques with regard to treatment duration. "

    ABSTRACT: Anxiety disorders are one of the disorders most frequently requested for psychological attention. The purpose of this study is to identify the factors that can explain a longer duration of psychological treatment for anxiety disorders. 202 patients from the University Psychology Clinic of the Complutense University of Madrid were analyzed. Multivariate regression analysis showed that the presence of obsessive-compulsive disorder and the application of arousal control techniques followed by modeling and other specific techniques were the best predictors of treatment duration. Reducing as much as possible the number of techniques applied without reducing intervention efficacy is suggested. In some disorders that produce a greater life disorganization, it may be useful to try to organize the patient´s life either as a first goal or at the same time as the intervention program, so as to increase its effectiveness and reduce the number of sessions.

    • "Two studies of mindfulness-based treatment for depression also found that decreased levels of worry and rumination (change scores) mediated the effect of treatment on depression outcome (Van Aalderen et al., 2012). Similarly, changes in worry (measured daily) have been shown to partially mediate the effect of time on decreased anxiety in CBT and applied relaxation for GAD (Donegan & Dugas, 2012). To the authors' knowledge, there is only one study that has examined changes in content independent RNT and treatment outcome. "

    ABSTRACT: Repetitive negative thinking (RNT) is a common symptom across depression and anxiety disorders and preliminary evidence suggests that decreases in rumination and worry are related to improvement in depression and anxiety symptoms. However, despite its prevalence, relatively little is known about transdiagnostic RNT and its temporal associations with symptom improvement during treatment. The current study was designed to examine the influence of RNT on subsequent depression and anxiety symptoms during treatment. Participants (n = 131; 52% female; 93% White; M = 34.76 years) were patients presenting for treatment in a brief, cognitive behavior therapy based, partial hospitalization program. Participants completed multiple assessments of depression (Center for the Epidemiological Studies of Depression-10 scale), anxiety (the 7-item Generalized Anxiety Disorder Scale), and repetitive negative thinking (Perseverative Thinking Questionnaire) over the course of treatment. Results indicated statistically significant between and within person effects of RNT on depression and anxiety, even after controlling for the effect of time, previous symptom levels, referral source, and treatment length. RNT explained 22% of the unexplained variability in depression scores and 15% of the unexplained variability in anxiety scores beyond that explained by the control variables. RNT may be an important transdiagnostic treatment target for anxiety and depression. Copyright © 2015 Elsevier Ltd. All rights reserved.

    • "uno de los objetivos psicoterapéuticos más frecuentes, siendo de especial relevancia en algunos problemas, como los trastornos de ansiedad que se encuentran entre los más habituales en la práctica clínica (Conrad y Roth, 2007; Donegan y Dugas, 2012; Hoyer, Beesdo, Gloster, Runge, Höfler, y Becker , 2009; Ost y Breitholtz, 2000). Por otro lado, se considera que las TR no presentan efectos secundarios indeseables , incluso que pueden utilizarse sin tener que responder a un déficit específico del paciente y que son útiles simplemente para mejorar la calidad de vida o disfrutar más de és- ta.

    ABSTRACT: The aim of this article is to describe the use of relaxation tech-niques (RT) in the practice of clinic psychology care. Relaxation techniques are analyzed considering what type of technique they are and their use, go-ing from a general overview to a specific diagnosis context and treatment results. 67.2 percent of 880 clinic patients with all types of diagnosis are women and the average age is 32.79 years old. The results show that some RT has been used in 70.5 per cent of the cases being breath control the most frequent one (72.3 per cent). It is mainly used for anxiety disorders (87.8%), somatoform disorder (84.2%) and impulse control disorder (77.8%). The use of these techniques is more frequent in cases of comor-bid disorder (82.4% versus 68%). Breathe control and progressive muscular relaxation techniques are used in about 69 per cent of discharged patients. The discussion of this paper focuses on the results of using RT regardless of the diagnosis.
