A Bayesian approach to mitigation of publication bias

The reliability of published research findings in psychology has been a topic of rising concern. Publication bias, or treating positive findings differently from negative findings, is a contributing factor to this “crisis of confidence,” in that it likely inflates the number of false-positive effects in the literature. We demonstrate a Bayesian model averaging approach that takes into account the possibility of publication bias and allows for a better estimate of true underlying effect size. Accounting for the possibility of bias leads to a more conservative interpretation of published studies as well as meta-analyses. We provide mathematical details of the method and examples.     

Hare Psychopathy Checklist-Revised

The Hare Psychopathy Checklist-Revised (PCL-R) is among the most frequently used instruments for the assessment of psychopathic traits. In the scope of the German adaptation of the PCL-R, normative data were collected from a sample of adult male offenders. Based on these data the factor structure and reliability of the German language version of the PCL-R are discussed in the first section of the article. The assessment of a model with four facets and two superordinate factors showed a very good agreement with the empirical data. In addition, examination of interrater agreement and internal consistency indicated that the PCL-R is a reliable measure. In the second part of the paper recommendations are provided for the correct application of the PCL-R. The focus lies on the correct performance, evaluation and interpretation of PCL-R test results with respect to key indices and the dimensional structure of the psychopathy construct.     

Bayesian inference for psychology,part III: Parameter estimation in nonstandard models

We demonstrate the use of three popular Bayesian software packages that enable researchers to estimate parameters in a broad class of models that are commonly used in psychological research. We focus on WinBUGS, JAGS, and Stan, and show how they can be interfaced from R and MATLAB. We illustrate the use of the packages through two fully worked examples; the examples involve a simple univariate linear regression and fitting a multinomial processing tree model to data from a classic false-memory experiment. We conclude with a comparison of the strengths and weaknesses of the packages. Our example code, data, and this text are available via https://osf.io/ucmaz/.

Teilstationäre Psychotherapie

Psychotherapeutic day clinics increasingly take over responsibility for the treatment of patients who cannot be cared for satisfactorily, respectively, at all in an inpatient setting. Psychotherapy in a day clinic setting is a treatment in its own right which has progressively established itself between inpatient and outpatient treatment. Empirically raised up to date data prove the efficacy and the efficiency of psychotherapeutic treatment in day clinics. Accordingly, the goal of the present study is to investigate the outcomes of psychotherapeutic treatment in a day clinic with a psychodynamic concept. Since 1996 the psychotherapeutic day clinic Basel empirically assesses the treatment course of all admitted patients. Patients and therapists fill in questionnaires upon admittance, two months into the course of treatment and upon discharge (SCL-90-R, PSKB-Se-R, OPD etc.) Our results indicate that significant improvements of symptoms as well as of socio-communicative competency can be achieved during treatment which remain stable even after discharge (first follow-up three months after discharge). Comparing outcome data of patients treated in full-time inpatient setting and of patients who undergo partial hospitalization we found that outcome was at least equivalent. Additionally we found that the diagnosis of a personality disorder influenced treatment results significantly in some symptom specific spheres.     

The Peace Work and Witness of the Churches in the German Democratic Republic and the World Disorder of the 21st Century

This article is an edited translation of an address given in Erfurt, Germany, on 12 May 2019, to celebrate the 90th birthday of Heino Falcke, dean (provost) of Erfurt from 1973 until his retirement in 1994. Falcke, who was also a member of the working group on Church and Society of the World Council of Churches, played a central role in developing the theological and ethical response of Protestant churches in the German Democratic Republic (GDR) to the threats to peace in a nuclear age. This was expressed in the “renunciation of the spirt, logic, and practice of deterrence.” This article seeks to set out the insights from the peace work and witness of the churches in the GDR against the background of the “world disorder of the 21st century.”     

Integrating commons dilemma findings in a general dynamic model of cooperative behavior in resource crises

The research on commons dilemmas is characterized by innumerable published findings, each standing relatively isolated from the other. To date there is little integration of the findings under a unified concept. The present contribution aims to integrate already existing findings in a general dynamic model of cooperative behavior in resource crises by means of computer simulation. The model postulates that people base their decisions regarding resource use on both ecological and social information. Whether or not ecological or social information will dominate, however, depends on people's social values, attributions, and their perceptions of the state of the resource. The advantage of the simulation method used is that successful integration of the findings can be shown explicitly, as the simulation then replicates the experimental data. With the model presented here, it is also possible to let variables work together whose interaction has not yet been investigated in real experiments. For instance, the simulation model allows us to hypothesize that people, in dependency upon their resource uncertainty and in dependency upon their attributions, utilize a resource completely differently if the resource is in an optimal or sub‐optimal condition.
