Changing Me,Changing Us: Relationship Quality and Collective Efficacy as Major Outcomes in Systemic Couple Therapy

We examine the sensitivity to change in the Evaluation of Social Systems (EVOS) scale, which assesses relationship quality and collective efficacy. In Study 1 we conducted a waitlist‐control, short‐term couple therapy RCT study (N = 43 couples) with five systemic therapy sessions treating communication and partnership problems; our intent was to provide high external validity. Construct validity of EVOS was assessed by comparison with additionally applied scales (Family Scales; Outcome Questionnaire, OQ‐45.2). In Study 2, N = 332 individuals completed an experiment with high internal validity in order to verify sensitivity to change in three different social contexts. Results from Study 1 revealed a significant increase in relationship quality in the treatment group directly after treatment, as compared to the control group. Sensitivity to change was slightly better for EVOS than for other measures. While this positive change could not be fully sustained between posttreatment and a 4‐week follow‐up, EVOS score did not fall below baseline and pretreatment levels, supporting moderate‐to‐large sensitivity to change. Study 2 supported high sensitivity to change in EVOS for couple relations, family relations, and work‐team relationships. Therefore, EVOS can be used as an outcome measure to monitor the process of systemic interventions focusing on relationship quality and collective efficacy. Due to its sensitivity to change, EVOS can provide evidence for treatment success with regard to relationship aspects.     

Eyewitness identification in simultaneous and sequential lineups: an investigation of position effects using receiver operating characteristics

For decades, sequential lineups have been considered superior to simultaneous lineups in the context of eyewitness identification. However, most of the research leading to this conclusion was based on the analysis of diagnosticity ratios that do not control for the respondent’s response criterion. Recent research based on the analysis of ROC curves has found either equal discriminability for sequential and simultaneous lineups, or higher discriminability for simultaneous lineups. Some evidence for potential position effects and for criterion shifts in sequential lineups has also been reported. Using ROC curve analysis, we investigated the effects of the suspect’s position on discriminability and response criteria in both simultaneous and sequential lineups. We found that sequential lineups suffered from an unwanted position effect. Respondents employed a strict criterion for the earliest lineup positions, and shifted to a more liberal criterion for later positions. No position effects and no criterion shifts were observed in simultaneous lineups. This result suggests that sequential lineups are not superior to simultaneous lineups, and may give rise to unwanted position effects that have to be considered when conducting police lineups.     

A latent trait model for response times on tests employing the proportional hazards model

For computer-administered tests, response times can be recorded conjointly with the corresponding responses. This broadens the scope of potential modelling approaches because response times can be analysed in addition to analysing the responses themselves. For this purpose, we present a new latent trait model for response times on tests. This model is based on the Cox proportional hazards model. According to this model, latent variables alter a baseline hazard function. Two different approaches to item parameter estimation are described: the first approach uses a variant of the Cox model for discrete time, whereas the second approach is based on a profile likelihood function. Properties of each estimator will be compared in a simulation study. Compared to the estimator for discrete time, the profile likelihood estimator is more efficient, that is, has smaller variance. Additionally, we show how the fit of the model can be evaluated and how the latent traits can be estimated. Finally, the applicability of the model to an empirical data set is demonstrated.     

Die Behandlung von Borderline-Persönlichkeitsstörungen

Zusammenfassung Bereits 1681 beklagte sich ein englischer Arzt in einem Brief über Patienten, die ohne jedes Ma? jene lieben, die sie alsbald ohne jeden Grund hassen würden. Weiterhin seien pl?tzliche Ausbrüche von Wut, Schmerz, Angst oder ?hnlichen Emotionen zu beobachten. Mit dieser frühen Beschreibung typischer Borderline-Symptome wird die Darstellung der Entwicklung der Theorie der Borderline-St?rung von den Anf?ngen bis heute eingeleitet. Vor diesem Hintergrund werden der Stand der Diagnostik und die derzeit wichtigen Behandlungskonzepte umrissen, und zwar die psychodynamischen, verhaltenstherapeutischen und klientenzentrierten Ans?tze. Es wird dargelegt, welche Antworten es auf die Frage gibt, was das angemessene therapeutische Setting ist, insbesondere mit Blick auf station?re Behandlungskonzepte. Die vorliegenden empirischen Studien best?tigen die Wirksamkeit von Psychotherapie bei Borderline-St?rungen. Die geringe Zahl der Studien belegt aber auch die Schwierigkeit der empirischen Forschung in diesem Bereich. Der abschlie?ende Ausblick in die Zukunft der Psychotherapie der Borderline-Pers?nlichkeitsst?rungen prognostiziert eine weitere Zunahme von Pers?nlichkeitsst?rungen im Spektrum psychiatrischer Erkrankungen und eine zunehmende Differenzierung des Behandlungsangebots bzw. Spezialisierung der Behandler.      

Letter-detection patterns in German: A window to the early extraction of sentential structure during reading

Letters are more difficult to detect in function words than in content words, presumably because function words serve to cue sentential structure but recede to the background as meaning unfolds. This function disadvantage was found for the definite article in German for all three genders and all four cases, but it was more pronounced when the article appeared in a nominative noun phrase than in an object noun phrase. It was also more pronounced for the typical subject-predicate-object sentential format than for the object-predicate-subject sentential format and also when the definite article unequivocally specified the case of a phrase than when it was ambiguous. The results suggest that the structural frames established on line in reading are finely tuned to both phrase-level and sentence-level organization.
