Stressbew?ltigungsintervention am Arbeitsplatz

Background

Occupational stress is considered a major risk factor for a wide range of health outcomes. To examine long-term effects on perceived stress reactivity a randomized controlled trial [1?year after stress management intervention (SMI)] was implemented in a metal working plant.

Method

A total of 174 participants were randomly assigned to an intervention (IG) or a waiting control group (CG) and underwent a group-based program over 2 days, followed by 2-3?h booster sessions. The primary endpoint was perceived stress reactivity (Stress Reactivity Scale, SRS), while secondary endpoints were anxiety and depression (Hospital Anxiety and Depression Scale, HADS), salivary cortisol and alpha-amylase.

Results

SRS scores decreased in both groups. A two factor ANOVA proved greater reduction in the IG. For SRS, the effect size (Cohen??s d) after 1?year was d=0.416 in the IG and d=0.166 in the CG. Alpha-amylase as a measure of sympathetic nervous system activation decreased more strongly in the IG. Reduction of depression and anxiety was higher in the IG but did not reach statistical significance.

Conclusion

The conducted SMI is effective over a longer period in reducing perceived stress reactivity and sympathetic activation.     

Implicit and explicit emotional behavior and mindfulness

The objective of this study was to examine whether the “step back and watch” attitude of mindfulness manifests in less emotional behavior. We hypothesized that the “acceptance” facet of mindfulness, but not the “presence” facet, is negatively associated with the magnitude of emotional behavior in four tests, i.e., (1) rating of words, (2) rating of aversive and neutral pictures, and (3) evaluative conditioning (EC). Additionally, we hypothesized that (4) the acceptance facet is associated with increased reaction time (RT) in an emotional Stroop test, and that the presence facet is associated with decreased RT and lower error rate. The sample consisted of N = 247 non-clinical adults and was tested in a cross-sectional study. The results provide partial evidence that the acceptance facet of mindfulness may be associated with less aversive reactions towards aversive stimuli. Future studies should substantiate these findings but also determine their clinical relevance.     

Acute psycho-social stress does not disrupt item-method directed forgetting, emotional stimulus content does

It has been shown that stress affects episodic memory in general, but knowledge about stress effects on memory control processes such as directed forgetting is sparse. Whereas in previous studies item-method directed forgetting was found to be altered in post-traumatic stress disorder patients and abolished for highly arousing negative pictorial stimuli in students, no study so far has investigated the effects of experimentally induced psycho-social stress on this task or examined the role of positive picture stimuli. In the present study, 41 participants performed an item-method directed forgetting experiment while being exposed either to a psychosocial laboratory stressor, the Trier Social Stress Test (TSST), or a cognitively challenging but non-stressful control condition. Neutral and positive pictures were presented as stimuli. As predicted, salivary cortisol level as a biological marker of the human stress response increased only in the TSST group. Still, both groups showed directed forgetting. However, emotional content of the employed stimuli affected memory control: Directed forgetting was intact for neutral pictures whereas it was attenuated for positive ones. This attenuation was primarily due to selective rehearsal improving discrimination accuracy for neutral, but not positive, to-be-remembered items. Results suggest that acute experimentally induced stress does not alter item-method directed forgetting while emotional stimulus content does.     

Brain potentials for derivational morphology: an ERP study of deadjectival nominalizations in Spanish

This study investigates brain potentials to derived word forms in Spanish. Two experiments were performed on derived nominals that differ in terms of their productivity and semantic properties but are otherwise similar, an acceptability judgment task and a reading experiment using event-related brain potentials (ERPs) in which correctly and incorrectly formed derived words were presented in sentence contexts. The first experiment indicated productivity differences between the different nominalization processes in Spanish. The second experiment yielded a pattern of ERP responses that differed from both the familiar lexical-semantic and grammatical ERP effects. Violations of derivational morphology elicited an increased N400 component plus a late positivity (P600), unlike gender-agreement violations, which produced the biphasic LAN/P600 ERP pattern known from previous studies of morpho-syntactic violations. We conclude that the recognition of derived word forms engages both word-level (lexical-semantic) and decompositional (morpheme-based) processes.     

Survival processing in times of stress

Recent studies have found that processing information according to an evolutionary relevant (i.e., survival) scenario improves its subsequent memorability, potentially as a result of fitness advantages gained in the ancestral past. So far, research has not revealed much about any proximate mechanisms that might underlie this so-called survival processing advantage in memory. Intriguingly, research has shown that the memorability of stressful situations is enhanced via the release of stress hormones acting on brain regions involved in memory. Since survival situations habitually involve some degree of stress, in the present study, we investigated whether stress serves as a proximate mechanism to promote survival processing. Participants rated words for their relevance to either a survival or a neutral (moving) scenario after they had been exposed to a psychosocial stressor or a no-stress control condition. Surprise retention tests immediately following the rating task revealed that survival processing and acute stress independently boosted memory performance. These results therefore suggest that stress does not serve as a proximate mechanism of the survival processing advantage in memory.     

Sleep normalization and decrease in dissociative experiences: evaluation in an inpatient sample

We conducted a longitudinal study to investigate the relation between sleep experiences and dissociative symptoms in a mixed inpatient sample at a private clinic evaluated on arrival and at discharge 6 to 8 weeks later. Using hierarchical regression analyses and structural equation modeling, we found a link between sleep experiences and dissociative symptoms and determined that specifically decreases in narcoleptic experiences rather than insomnia accompany a reduction in dissociative symptoms. Although sleep improvements were associated with a general reduction in psychopathology, this reduction could not fully account for the substantial and specific effect that we found for dissociation. Our findings are consistent with Watson's (2001) hypothesis that disruptions in the sleep-wake cycle lead to intrusions of sleep phenomena into waking consciousness, resulting in dissociative experiences. Accordingly, sleep hygiene may contribute to the treatment or prevention of dissociative symptoms.     

Predicting adolescents' parent–child relationship quality from parental personality,marital conflict and adolescents' personality

Longitudinal influences on the relationships between parents and their adolescent children in 175 Austrian families were analysed with data from three measurement points over a time span of 18 years. We investigated the influences of parental personality, marital conflict and adolescents' personality on the father–child and mother–child relationships separately. Inconsistent with previous theories and empirical findings, we found almost no associations between parental personality and parent–child relationships. Marital conflict was associated with only the father–child relationship. Children's personality showed the most consistent associations with the parent–child relationship. Our data support the theory of dynamic interactionism, which postulates an interdependency of personality factors and social relationships.     

Psychophysical correlations,synchronicity and meaning

The dual‐aspect framework which Jung developed with Wolfgang Pauli implies that psychophysical phenomena are neither reducible to physical processes nor to conscious mental activity. Rather, they constitute a radically novel kind of phenomena, deriving from correlations between the physical and the mental. In synchronistic events, a particular subclass of psychophysical phenomena, these correlations are explicated as experienced meaning.     

Response Latencies and Attitude‐Behavior Consistency in a Direct Democratic Setting: Evidence from a Subnational Referendum in Germany

This article addresses the role of response latencies in affecting the attitude‐behavior consistency in a German subnational referendum. As voters faced a comparatively easy choice in this referendum, it puts the hypothesis concerning the role of attitude accessibility in increasing attitude‐behavior consistency to a particularly hard test. Utilizing data from a two‐wave panel survey, the analysis examines the effect of response latencies on the attitude‐behavior consistency concerning participation and vote choice. The evidence confirms hypotheses derived from attitude‐consistency theory only in a limited number of cases. The institutional setting and the nature of choice thus appear to make a difference. Moreover, substantive findings depend partially upon the procedure to measure response latencies. Accordingly, sensitivity tests should be employed by default. Irrespective of operationalization, response latencies play a crucial role when it comes to respondents who answered that they would “perhaps” participate. Whereas a quickly uttered “perhaps” was indicative of a rather low likelihood of participation, a slowly given “perhaps” indicated a considerably high probability.     

Contextual Bias in Verbal Credibility Assessment: Criteria‐Based Content Analysis,Reality Monitoring and Scientific Content Analysis

Verbal credibility assessment encompasses several methods used to evaluate the credibility of statements by examining their content. In two experiments, we tested to what extent these methods are sensitive to contextual bias. Four statements were presented, although their context was manipulated by confronting raters with extra‐domain information that either enhanced or diminished the credibility of the statements. In Experiment 1, 32 police officers analysed the statements using scientific content analysis. In Experiment 2, 128 undergraduates analysed the statements using criteria derived from criteria‐based content analysis, reality monitoring or scientific content analysis. Results showed that all three methods were equally vulnerable to contextual bias. Copyright © 2013 John Wiley & Sons, Ltd.
