Indikation zur ambulanten Nachsorge (Curriculum Hannover) in der Psychosomatischen Rehabilitation

Outpatient psychosomatic aftercare (Curriculum Hannover) was introduced nationwide in 2000 by the pension scheme. The effectiveness and efficacy of outpatient psychosomatic aftercare has been widely researched. This publication presents an indication-model based on four levels (capacity, participation, activity and impairment) whereas empirical results and clinical experience concerning participation in psychosomatic outpatient aftercare following an in-patient rehabilitation are considered in accordance with the international classification of functioning, disability and health.     

Average Effects Based on Regressions with a Logarithmic Link Function: A New Approach with Stochastic Covariates

Psychometrika - Researchers often use regressions with a logarithmic link function to evaluate the effects of a treatment on a count variable. In order to judge the average effectiveness of the...     

Analysis of Variance Models with Stochastic Group Weights

The analysis of variance (ANOVA) is still one of the most widely used statistical methods in the social sciences. This article is about stochastic group weights in ANOVA models – a neglected aspect in the literature. Stochastic group weights are present whenever the experimenter does not determine the exact group sizes before conducting the experiment. We show that classic ANOVA tests based on estimated marginal means can have an inflated type I error rate when stochastic group weights are not taken into account, even in randomized experiments. We propose two new ways to incorporate stochastic group weights in the tests of average effects – one based on the general linear model and one based on multigroup structural equation models (SEMs). We show in simulation studies that our methods have nominal type I error rates in experiments with stochastic group weights while classic approaches show an inflated type I error rate. The SEM approach can additionally deal with heteroscedastic residual variances and latent variables. An easy-to-use software package with graphical user interface is provided.     

Reminiscing together: joint experiences,epistemic groups,and sense of self

In this essay, I consider a kind of social group that I call ‘epistemic’. It is constituted by its members’ possession of perceptually grounded common knowledge, which endows them with a particular kind of epistemic authority. This authority, I argue, is invoked in the activity of ‘joint reminiscing’—of remembering together a past jointly experienced event. Joint reminiscing, in turn, plays an important role in the constitution of social and personal identity. The notion of an epistemic group, then, is a concept that helps explain an important aspect of a subject’s understanding of who she is.

     

Self-control motivationally reconsidered: “Acting” self-controlled is different to “being good” at self-control

Motivation and Emotion - Self-control is typically conceptualized as an inherent human skill, focusing on the imperative control of thoughts, feelings, and behavior. In the present research, we...     

How do personality disorders modify suicide risk?

There is a lack of psychological autopsy studies assessing the influence of axis II disorders on other risk factors for suicide. Therefore, we investigated if the estimated suicide risk for axis I disorders and socio-demographic factors was modified by personality disorders. Psychiatric disorders were evaluated by a semi-structured interview including the Structured Clinical Interview for DSM-IV Axis I (SCID-I) and Personality Disorders (SCID-II) by psychological autopsy method in 163 completed suicides and by personal interview in 396 population-based control persons. Personality disorders modify suicide risk, differently for affective disorders, substance use disorders, smoking, life events during the last three months, and socio-demographic factors such as being single. Estimated suicide risk for socio-demographic factors and life events is not substantially altered following adjustment for affective disorders or substance use disorders. These findings suggest that treatment of personality disorders is essential for suicide prevention.     

Sound source location modulates the irrelevant-sound effect

Participants memorized lists of visually presented digits in silence or while ignoring distractor sounds that either came from the front and thus from the direction in which participants' attention was oriented, or from behind. Distractor sounds impaired recall performance, but the largest impairment was observed when the sound source was directionally close to the frontal visual target display. The results are consistent with the assumption of cross-modal attentional links in models of attention, and they are problematic for explanations of the irrelevant-sound effect within working memory models that do not specify an explicit role of attention in the maintenance of information for immediate serial recall.     

The influence of syllable onset complexity and syllable frequency on speech motor control

Functional imaging studies have delineated a "minimal network for overt speech production", encompassing mesiofrontal structures (supplementary motor area, anterior cingulate gyrus), bilateral pre- and postcentral convolutions, extending rostrally into posterior parts of the inferior frontal gyrus (IFG) of the language-dominant hemisphere, left anterior insula as well as bilateral components of the basal ganglia, the cerebellum, and the thalamus. In order to further elucidate the specific contribution of these cerebral regions to speech motor planning, subjects were asked to read aloud visually presented bisyllabic pseudowords during functional magnetic resonance imaging (fMRI). The test stimuli systematically varied in onset complexity (CCV versus CV) and frequency of occurrence (high-frequency, HF versus low-frequency, LF) of the initial syllable. A cognitive subtraction approach revealed a significant main effect of syllable onset complexity (CCV versus CV) at the level of left posterior IFG, left anterior insula, and both cerebellar hemispheres. Conceivably, these areas closely cooperate in the sequencing of subsyllabic aspects of the sound structure of verbal utterances. A significant main effect of syllable frequency (LF versus HF), by contrast, did not emerge. However, calculation of the time series of hemodynamic activation within the various cerebral structures engaged in speech motor control revealed this factor to enhance functional connectivity between Broca's area and ipsilateral anterior insula.
