Mediators of Change in Cognitive Behavior Therapy for Clinical Burnout

Evidence supporting the effectiveness of cognitive behavior therapy (CBT) for stress-related illness is growing, but little is known about its mechanisms of change. The aim of this study was to investigate potential mediators of CBT for severe stress in form of clinical burnout, using an active psychological treatment as comparator. We used linear mixed models to analyze data from patients (N = 82) with clinical burnout who received either CBT or another psychological treatment in a randomized controlled trial. Potential mediators (i.e., sleep quality, behavioral activation, perceived competence, and therapeutic alliance) and outcome (i.e., symptoms of burnout) were assessed weekly during treatment. The results showed that the positive treatment effects on symptoms of burnout favoring CBT (estimated between-group d = 0.93) were mediated by improvements in sleep quality, ab = -0.017, 95% CI_asymmetric [-0.037, -0.002], and increase in perceived competence, ab = -0.037, 95% CI_asymmetric [-0.070, -0.010]. Behavioral activation, ab = -0.004 [-0.016, 0.007], and therapeutic alliance, ab = 0.002 [-0.006, 0.011], did not significantly mediate the difference in effects between the treatments. Improving sleep quality and increasing perceived competence may thus constitute important process goals in order to attain symptom reduction in CBT for clinical burnout.     

Single‐item big five ratings in a social network design

To develop and validate an ultra‐short measure to assess the Big Five in social network designs, the unipolar items of the Ten‐Item Personality Inventory were adapted to create a bipolar single‐item scale (TIPI‐r), including a new Openness item. Reliability was examined in terms of the internal consistency and test–retest stability of self‐ratings and peer‐rating composites (trait reputations). Validity was examined by means of convergence between TIPI‐r and Big Five Inventory (BFI) scores, self‐peer agreement and projection (intra‐ individual correlation between self‐ and peer‐ratings). The psychometric quality of the TIPI‐r differed somewhat between scales and the different reliability and validity criteria. The high reliability of the peer‐rating composites motivates to use the TIPI‐r in future studies employing social network designs. Copyright © 2007 John Wiley & Sons, Ltd.     

Adolescents' music preferences and personality characteristics

The present paper examined the structure of Dutch adolescents' music preferences, the stability of music preferences and the relations between Big‐Five personality characteristics and (changes in) music preferences. Exploratory and confirmatory factor analyses of music‐preference data from 2334 adolescents aged 12–19 revealed four clearly interpretable music‐preference dimensions: Rock, Elite, Urban and Pop/Dance. One thousand and forty‐four randomly selected adolescents from the original sample filled out questionnaires on music preferences and personality at three follow‐up measurements. In addition to being relatively stable over 1, 2 and 3‐year intervals, music preferences were found to be consistently related to personality characteristics, generally confirming prior research in the United States. Personality characteristics were also found to predict changes in music preferences over a 3‐year interval. Copyright © 2007 John Wiley & Sons, Ltd.     

Maladaptive perfectionism as an intervening variable between psychological control and adolescent depressive symptoms: a three-wave longitudinal study.

Maladaptive perfectionism has been postulated as an intervening variable between psychologically controlling parenting and adolescent internalizing problems. Although this hypothesis has been confirmed in a number of cross-sectional studies, it has not yet been examined from a longitudinal perspective. Findings from this 3-wave longitudinal study show that parental psychological control (as indexed by parent and adolescent reports) at age 15 years predicted increased levels of maladaptive perfectionism 1 year later. Maladaptive perfectionism, in turn, predicted increased levels of adolescent depressive symptoms again 1 year later and acted as a significant intervening variable between parental psychological control at Time 1 and depressive symptoms at Time 3. Multigroup analyses show that the model tested was consistent across gender for paternal psychological control but not for maternal psychological control. Suggestions for future research are outlined.     

Socialising technology: the archives of István Hajnal

István Hajnal is one of the most remarkable historians and a forerunner of research on the history of communication. He developed his radical theories on the connections between writing as a technique and social structure mainly in the first half of the twentieth century. He emphasized, in a unique way, the importance of technology for social development arguing that the transformation of social structures and the individual within stand in a mutual and interdependent relation with various technological systems. While doing so he reconsidered Max Weber’s concepts of traditionalism and rationalism from a so to speak Heideggerian angle.     

When emotions of others affect decisions in public good dilemmas: An instrumental view

The present research examines whether the emotional display (i.e. anger vs. guilt) of another group member affects people's decision‐making in a public good dilemma. In two experiments we investigated whether the expressed emotion is particularly informative when communicated by a group member who is highly instrumental in reaching the provision point. A first experiment demonstrated that participants were more likely to exit the group when anger as opposed to guilt was communicated, but especially when the group member displaying the emotion was able to contribute many endowments to the public good. Expected justice (based on past inferences) in the group mediated this effect, suggesting that communicated anger signals more than guilt that the group will not set out to achieve fairness. In agreement with this, a second experiment showed that when it was not possible to exit the group, participants preferred to install a democratic leader more when a wealthy group member communicated anger as opposed to guilt. Additionally, this study provided experimental evidence that a communicated emotion is only used for subsequent decision‐making when more explicit information (i.e. a promise to contribute) is absent.

The Development of Delinquency and Perceived Friendship Quality in Adolescent Best Friendship Dyads

The present study examines both the unique and the combined role of best friends' delinquency and perceived friendship quality in the development of adolescent delinquency. Questionnaire data were gathered from 435 Dutch adolescent best friends (mean age at first wave = 12.97) over a period of 5 years with annual assessments. Results showed that mean levels of delinquency and perceived friendship quality increased over time. Adolescent best friends were highly similar in both mean levels and changes in delinquency over time. For boys, similarity in mean level delinquency between best friends was higher than for girls. In addition, only for boys, friends' delinquency is associated with increases in adolescent delinquency over time, and adolescents' delinquency is associated with increases in friends' delinquency over time. No bidirectional longitudinal associations were found between perceived friendship quality and adolescent delinquency. No interaction effects between friendship quality and friends' delinquency on adolescent delinquency were found. Thus, findings were more in support of the differential association theory than of the social control theory.     

The intergenerational transmission of authoritarianism: The mediating role of parental goal promotion

This study examined the intergenerational transmission of adolescent authoritarian submission (Right-Wing Authoritarianism or RWA) and authoritarian dominance (Social Dominance Orientation or SDO). It was hypothesized that the type of goals that parents promote (i.e., conservation versus openness to change and extrinsic versus intrinsic goal promotion) would mediate any direct association between parents’ and adolescents’ authoritarian attitudes. This hypothesis was examined in a sample of middle adolescents and their parents. First, a significant parent–child concordance was found for RWA and SDO. Second, whereas parental RWA predicted parental promotion of conservation goals (rather than openness to change goals) as well as the promotion of extrinsic goals (rather than intrinsic goals), parental SDO predicted parental promotion of extrinsic goals only. Third, process analyses showed that, whereas parental conservation goal promotion mediates the relationship between parent and child RWA, parental extrinsic goal promotion mediates the relationship between parent and child SDO.     

How does dominance rank status affect individual and social learning performance in the dog (<Emphasis Type="Italic">Canis familiaris</Emphasis>)?

Dogs can learn effectively to detour around a V-shaped fence after observing a demonstration from either an unfamiliar human or dog demonstrator. We found earlier that there is substantial individual variation between the dogs’ performance, even when using the same experimental conditions. Here, we investigate if the subjects’ relative dominance rank with other dogs had an effect on their social learning performance. On the basis of the owners’ answers to a questionnaire, subjects from multi-dog homes were sorted into groups of dominant and subordinate dogs. In Experiment 1, dominant and subordinate dogs were tested without demonstration and we did not find any difference between the groups—they had similarly low detour performances on their own. In Experiment 2 and 3, dogs from single dog and multi-dog households were tested in the detour task with demonstration by an unfamiliar dog, or human, respectively. The results showed that social learning performance of the single dogs fell between the dominant and subordinate multi-dogs with both dog and human demonstration. Subordinate dogs displayed significantly better performance after having observed a dog demonstrator in comparison to dominant dogs. In contrast, the performance of dominant and subordinate dogs was almost similar, when they observed a human demonstrator. These results suggest that perceived dominance rank in its own group has a strong effect on social learning in dogs, but this effect seems to depend also on the demonstrator species. This finding reveals an intricate organization of the social structure in multi-dog households, which can contribute to individual differences existing among dogs.     

Encouraging Cooperation: Revisiting Solidarity and Commitment Effects in Prisoner's Dilemma Games1

Pre‐play discussion consistently increases cooperation in dilemma interactions. Most explanations of this “cheap‐talk” effect are based on either commitment or group solidarity effects. Because discussion about the upcoming dilemma allows participants to make promises and creates group solidarity, the 2 explanations are often confounded. This paper aims to clarify past results by having participants engage in an unrelated discussion prior to a dilemma interaction. We find that solidarity effects can be induced by minimal group categorizations, but are relatively weak. Discussions involving consequential but unrelated coordination tasks are shown to prime cooperative norms and increase cooperation with both in‐group and out‐group members. Our findings suggest that cheap talk may work for even cheaper reasons than previously thought.
