Behandlungsmotivation und Indikation von Psychotherapie

Concepts and results of research into treatment motivation under psychotherapy are discussed with regard to the question whether decisions for indications on the basis of the motivational characteristics of patients are reasonable. Established concepts and broader theories of treatment motivation as well as diagnostic tools for the assessment are presented. Subsequently, empirical results for the effects of motivational factors on the maintenance and success of psychotherapy are briefly sketched. Approaches aimed at the enhancement of treatment motivation before and during psychotherapeutic processes are then illustrated. Finally, it is emphasized that, in turn, features of individual therapeutic processes may provide a basis for the indication of motivational enhancement interventions, thus supporting the notion of a dynamic nature of treatment motivation.     

Consequences of voluntary job changes in Germany: A multilevel analysis for 1985–2013

Analyzing the development of the consequences of voluntary job changes in Germany between 1985 and 2013, the study focuses on income gains and job satisfaction increases. Drawing on arguments of the job-search literature on the one hand and the proliferation of choices on the other we investigate whether the returns of job changes have increased or decreased. Results show that income gains have decreased over time while the job satisfaction surplus has remained stable. We further conclude that in determining the outcomes of job changes over time, structural factors seem to be more important than individual ones.     

Somatic symptom reporting has a dimensional latent structure: Results from taxometric analyses

Medically unexplained symptoms (MUS) are one of the key features of somatoform disorders. Although MUS are currently treated as both categorical (in terms of the diagnosis of somatoform disorders) and dimensional (in terms of quantitative measures of somatization/somatic symptom reporting), little is known about the empirical latent structure of MUS. Using taxometric analyses, the latent structure of somatic symptom reporting was analyzed with the Patient Health Questionnaire (PHQ)-15 in two student samples (N = 782 and N = 2,577) and a primary care sample (N = 519). We applied three popular taxometric methods: Maximum Eigenvalue (MAXEIG), Mean Above Minus Below a Cut (MAMBAC) and Latent-Mode (L-Mode). Simulation data were created to evaluate the appropriateness of the data for our analyses and to create the comparison curve fit index (CCFI) as an objective outcome measure. The results of all taxometric methods in any of the three data sets were in favor of a dimensional solution (CCFI < .50). Simulated taxonic and dimensional datasets differed substantially and the samples were appropriate for taxometric analysis. Accordingly, the latent structure of somatization/somatic symptom reporting as assessed by the PHQ-15 is dimensional in both primary care and student samples. Implications regarding the practical application as well as models of etiology and pathogenesis of somatic symptom reporting are discussed.

Intact risk-based decision making in rats with prefrontal or accumbens dopamine depletion

The medial prefrontal cortex (mPFC) and the core region of the nucleus accumbens (AcbC) are key regions of a neural system that subserves risk-based decision making. Here, we examined whether dopamine (DA) signals conveyed to the mPFC and AcbC are critical for risk-based decision making. Rats with 6-hydroxydopamine or vehicle infusions into the mPFC or AcbC were examined in an instrumental task demanding probabilistic choice. In each session, probabilities of reward delivery after pressing one of two available levers were signaled in advance in forced trials followed by choice trials that assessed the animal??s preference. The probabilities of reward delivery associated with the large/risky lever declined systematically across four consecutive blocks but were kept constant within four subsequent daily sessions of a particular block. Thus, in a given session, rats need to assess the current value associated with the large/risky versus small/certain lever and adapt their lever preference accordingly. Results demonstrate that the assessment of within-session reward probabilities and probability discounting across blocks were not altered in rats with mPFC and AcbC DA depletions, relative to sham controls. These findings suggest that the capacity to evaluate the magnitude and likelihood of rewards associated with alternative courses of action seems not to rely on intact DA transmission in the mPFC or AcbC.     

Understanding AIDS preventive behavior with casual and primary partners in homosexual men: The theory of planned behavior and the information-motivation-behavioral-skills model

Abstract

This study examined whether components from the Information-Motivation-Behavioral-Skills Model, in particular information, added explanatory power to factors derived from the Theory of Planned Behavior with respect to predicting AIDS-preventive behaviors among gay men. Participants were recruited from a longstanding cohort study in Amsterdam. Multivariate regression analyses showed that concepts from the Theory of Planned Behavior could account adequately for intentions to use condoms with casual as well as with steady partners. Actual behavior was best predicted by past behavior. In addition, structural equation modeling demonstrated that the causal paths as posited by Theory of Planned Behavior had a good fit to the data. From the presented findings implications for preventive interventions can be drawn. Specifically, interventions to increase condom use with casual partners need to focus at improving perceived behavioral control regarding this behavior, for instance through skills training. Interventions aimed at safer sex within steady relationships should take into account that the HIV-status of the individual and his partner plays an important role in the occurrence of unprotected anal sex in a romantic dyad.
