Abstract
Objective
Deficits of dyadic social interaction seem to diminish social functioning in schizophrenia. However, most previous studies are of a limited ecological validity due to decontextualized experimental conditions far off from real-world interaction. In this pilot study, we thus exposed participants to a more real-world-like situation to generate new hypotheses for research and therapeutic interventions.
Methods
Dyads of either participants with schizophrenia (n = 21) or control participants without mental disorder (n = 21) were presented with a 5-min emotionally engaging movie. The subsequent uninstructed dyadic interaction was videotaped and analyzed by means of a semi-quantitative, software-supported behavioral analysis.
Results
The patients with schizophrenia showed significant abnormalities regarding their social interaction, such as more negative verbalizations, a more open display of negative affect and gaze abnormalities. Their interaction behavior was mostly characterized by neutral affect, silence and avoidance of direct eye contact. Neutral affect was associated with poorer psychosocial performance. Verbal intelligence and empathy were associated with positive interaction variables, which were also not impaired by psychotic symptom severity.
Conclusion
In this real-world-like dyadic interaction, participants with schizophrenia show distinct abnormalities that are relevant to psychosocial performance and consistent with a hypothesized lack of attunement to interaffective situations.
期刊介绍:
As official journal of the Schizophrenia International Research Society (SIRS) Schizophrenia Research is THE journal of choice for international researchers and clinicians to share their work with the global schizophrenia research community. More than 6000 institutes have online or print (or both) access to this journal - the largest specialist journal in the field, with the largest readership!
Schizophrenia Research''s time to first decision is as fast as 6 weeks and its publishing speed is as fast as 4 weeks until online publication (corrected proof/Article in Press) after acceptance and 14 weeks from acceptance until publication in a printed issue.
The journal publishes novel papers that really contribute to understanding the biology and treatment of schizophrenic disorders; Schizophrenia Research brings together biological, clinical and psychological research in order to stimulate the synthesis of findings from all disciplines involved in improving patient outcomes in schizophrenia.
