The impact of experiential avoidance on the reduction of depression in treatment for borderline personality disorder

Background

Reducing symptoms of depression is an important target in the treatment of borderline personality disorder (BPD). Although current treatments for BPD are effective in reducing depression, the average post-treatment level of depression remains high.

Aim

To test whether experiential avoidance (EA) impedes the reduction of depression during treatment for BPD.

Method

EA and depression were assessed in 81 clients at baseline and 4-month intervals during 1 year of therapy. Simple correlations, hierarchical linear modeling, and latent difference score models were used to investigate the association between self-reports of EA and both self-reports and observer-based ratings of depression.

Results

EA was positively associated with greater severity of depression at all points of assessment, and changes in EA were positively associated with changes in depression. Moreover, EA significantly predicted less subsequent reduction in depression whereas no such effect was found for depression on subsequent EA.

Conclusion

The findings are consistent with the hypothesis that EA impedes the reduction of depression in the treatment of BPD and should thus be considered an important treatment target.     

When failing feels good—Relative prototypicality for a high-status group can counteract ego-threat after individual failure

Two studies demonstrate that members of high-status groups (i.e., men and students of business administration) but not members of low-status groups (i.e., women and education students) react with an increase in state self-esteem after an alleged poor performance on a fictitious intelligence test. This Failure-as-an-Asset (FA) effect is only observed when the high-status ingroup (i.e., men) is outperformed by a low-status outgroup (i.e., women). In this case, a poor performance will lead to a strong identification with the ingroup due to high ingroup prototypicality. As predicted, the effects of experiencing success or failure on self-esteem were mediated by identification with the ingroup.     

Goal congruency without stimulus congruency in bimanual coordination

Two experiments explored the role of stimulus congruency and goal congruency for the generation of object-oriented actions with two hands. Participants had to place two objects into either parallel or opposite orientations by carrying out either symmetrical or asymmetrical forearm rotations. Performance was superior when the required object orientations were identical rather than different, almost independent of the symmetry of the required arm movements. In extending previous research, goal congruency effects ensued even under conditions in which congruency of imperative response signals could not have contributed to goal congruency effects, either because only a single stimulus was used to indicate the required goals in an individual trial (Experiment 1) or such stimuli were absent at all (Experiment 2). The results thus confirm the importance of goal codes for the reconcilableness of bimanual actions, and rule out accounts in terms of stimulus-related processes.     

Storage and non-storage components of working memory predicting reasoning: A simultaneous examination of a wide range of ability factors

The current study examined basic cognitive abilities that are related to or included in the concept of working memory (WM): different WM components, three executive functions, simple short-term storage (STM), and sustained attention. Tasks were selected from well-established models and balanced in terms of content. The predictive power of storage and non-storage components of WM was examined. The same analyses were conducted with mental speed as an additional predictor of reasoning. Finally, we investigated whether the identified predictors of reasoning remain relevant when a general factor is considered in the analysis. The analyses revealed that short-term memory accounted for the relationship between complex span measures of WM and reasoning but not for the relationship between coordination and reasoning. These findings remained stable in the context of a mental speed and a general factor. The mental speed factor did not add an incremental contribution to the prediction of reasoning above and beyond short-term memory and coordination. The general factor was mainly built by mental speed tasks and acted as an additional predictor of reasoning besides STM and coordination. Thus, we concluded that reasoning ability can be explained by coordination, STM, and mental speed.     

Base rate effects on the IAT

We investigated the influence of stimulus base rates on the Implicit Association Test (IAT). Using an East/West-German attitude-IAT, we demonstrated that both overall response speed and differential response speed underlying IAT effects depend on the relative frequencies of the stimulus categories. First, when those stimuli that are more common in reality also occurred more frequently in the stimulus list, response speed generally increased. Second, IAT effects increased when congruent blocks profited from the compatibility of frequency-based response biases (i.e., frequent target stimuli and frequent valence stimuli mapped onto the same response key), whereas IAT effects decreased when incongruent trial blocks profited from response compatibility. These findings demonstrate that the stimulus context moderates the magnitude of the IAT effect. Simultaneously, they highlight the need to explore the extent to which implicit measures reflect properties of the task or the environment rather than attributes of test-takers.     

Go no-go performance under psychosocial stress: beneficial effects of implementation intentions

Acute stress has been found to have negative and implementation intentions (IIs) to have positive effects on cognitive performance. This study was the first to examine the effects of IIs on executive action control under acute psychosocial stress. Forty-two male subjects aged 21-39 years were randomly assigned to the Trier Social Stress Test (TSST) versus a rest condition. In addition, the instruction to the executive task (a go no-go task) was manipulated (IIs versus standard instruction). After the stress test, a dual-task procedure including a go no-go task was conducted. The TSST resulted in increases in cortisol response, heart rate and state anxiety compared to the rest condition. Acute stress significantly impaired go no-go performance, but only in the group without IIs. We conclude that under acute stress conditions executive functioning is reduced, but the use of IIs can be an effective strategy to overcome this negative effect.     

Latent state–trait theory: An application in sport psychology

ObjectiveQuestionnaires are often applied in sports psychology to measure a person's trait or state. However, the extent to which the questionnaire captures differences because of trait or state influences is often unclear. The latent state–trait (LST) theory offers the opportunity to separate both variance sources. This separation allows estimating specific reliability coefficients.DesignThe present paper gives a theoretical introduction to LST and its basic ideas. Using a real data set with N = 156 athletes we exemplify the steps necessary to derive the LST coefficients. All athletes filled out a comprehensive inventory assessing competitive anxiety on two occasions.MethodThe data are analysed with structural equation models based on LST principles.ResultsThe results confirm the questionnaire's trait saturation.ConclusionFinally, results are discussed in light of practical and theoretical implications.     

Same situation--different emotions: how appraisals shape our emotions

Appraisal theories of emotion hold that it is the way a person interprets a situation--rather than the situation itself--that gives rise to one emotion rather than another emotion (or no emotion at all). Unfortunately, most prior tests of this foundational hypothesis have simultaneously varied situations and appraisals, making an evaluation of this assumption difficult. In the present study, participants responded to a standardized laboratory situation with a variety of different emotions. Appraisals predicted the intensity of individual emotions across participants. In addition, subgroups of participants with similar emotional response profiles made comparable appraisals. Together, these findings suggest that appraisals may be necessary and sufficient to determine different emotional reactions toward a particular situation.     

Two Notions of Scientific Justification

Scientific claims can be assessed epistemically in either of two ways: according to scientific standards, or by means of philosophical arguments such as the no-miracle argument in favor of scientific realism. This paper investigates the basis of this duality of epistemic assessments. It is claimed that the duality rests on two different notions of epistemic justification that are well-known from the debate on internalism and externalism in general epistemology: a deontological and an alethic notion. By discussing the conditions for the scientific acceptability of empirical results, it is argued that intrascientific justification employs the deontological notion. Philosophical disputes such as those on scientific realism can by contrast be shown to rest on the alethic notion. The implications of these findings both for the nature of the respective epistemic projects and for their interrelation are explored.     

Realizing complex delayed intentions in young and old adults: The role of planning aids

Although it has been suggested that the delayed realization of intended actions should benefit from appropriate intention planning, empirical evidence on this issue is scarce. In three experiments, we examined whether and which planning aids provided in the intention formation phase affect delayed intention realization in young and old adults. One finding was that intention planning directly affected delayed intention realization: instructing participants to include the cue for appropriate intention initiation in their plans benefited delayed performance. Another finding was that older adults' performance was improved when they were guided in structuring their plan in combination with guidance in implementing this plan after a delay. In sum, the results point to the importance of plan-related factors for understanding the delayed realization of intended actions.
