Though there are known clinical predictors of response (e.g., higher age, presence of psychotic symptoms), there is a lack of knowledge concerning the impact of patients' expectations on treatment outcome and tolerability in terms of possible placebo/nocebo effects. In 31 patients with unipolar or bipolar depressive disorder, we used a questionnaire to investigate the patients' expectations of ECT effectiveness and tolerability prior to and in the course of the treatment. Additionally, the questionnaire was used after the ECT course for a final assessment. Depressive symptoms and putative side-effects were measured at each time point. General linear models were used to analyze the course of depressive symptoms and patients' expectation of ECT effectiveness and tolerability. ECT significantly reduced depressive symptoms with large effect sizes. Patients' rating of ECT effectiveness decreased in parallel: While responders' rating of ECT effectiveness remained stable on a high level, non-responders' rating decreased significantly. Group difference was significant after, but not prior to and during the treatment. Regarding tolerability, there was a (temporary) significant increase in the severity of self-rated symptoms such as headache and memory impairment. In contrast, patients' expectation and assessment of ECT tolerability remained unchanged, and their expectations prior to ECT had no impact on the occurrence of side-effects. These findings contradict the presence of relevant placebo/nocebo effects in the context of ECT when investigating a population of mostly chronic or treatment resistant patients with moderate to severe depressive disorder."],["dc.identifier.doi","10.1007/s00406-017-0840-8"],["dc.identifier.eissn","1433-8491"],["dc.identifier.pmid","28940099"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/57612"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.title","Influence of depressed patients' expectations prior to electroconvulsive therapy on its effectiveness and tolerability (Exp-ECT): a prospective study"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

Patients with psychiatric disorders are a vulnerable risk population for worsening of their condition and relapse of symptoms. This study investigates the pandemic-related course of psychosocial burden in patients with pre-existing mental disorders. With the newly developed Goettingen psychosocial Burden and Symptom Inventory (Goe-BSI) psychosocial burden has been traced retrospectively (1) before the pandemic (beginning of 2020), (2) at its beginning under maximum lockdown conditions (March 2020), and (3) for the current state after maximum lockdown conditions (April/May 2020). The Goe-BSI also integrates the Adjustment Disorder New Module (ADNM-20), assesses general psychiatric symptoms, and resilience. A total of 213 patients covering all major psychiatric disorders (ICD-10 F0-F9) were interviewed once in the time range from April, 24th until May 11th, 2020. Across all diagnoses patients exhibited a distinct pattern with an initial rise followed by a decline of psychosocial burden ( p  < 0.001, partial η 2  = 0.09; Bonferroni-corrected pairwise comparisons between all three time-points: p  < 0.05 to 0.001). Female gender and high ADNM-20 scores were identified as risk factors for higher levels and an unfavorable course of psychosocial burden over time. Most psychiatric symptoms remained unchanged. Trajectories of psychosocial burden vary in parallel to local lockdown restrictions and seem to reflect an adaptive stress response. For female patients with pre-existing mental disorders and patients with high-stress responses, timely and specific treatment should be scheduled. With the continuation of the pandemic, monitoring of long-term effects is of major importance, especially when long incubation times for the development of mental health issues are considered."],["dc.identifier.doi","10.1007/s00406-021-01268-6"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/85373"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-425"],["dc.relation.eissn","1433-8491"],["dc.relation.issn","0940-1334"],["dc.title","Evolution of psychosocial burden and psychiatric symptoms in patients with psychiatric disorders during the Covid-19 pandemic"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

It can be observed in many animals, such as bird flocks, shoals or herds of ungulates. Spatial attraction between humans as the central component of flocking behaviour has been simulated in a number of seminal models but it has not been detected experimentally in human groups so far. The two other sub-processes of this self-organised collective movement - collision avoidance and alignment - are excluded or held constant respectively in this study. We created a computer-based, multi-agent game where human players, represented as black dots, moved on a virtual playground. The participants were deprived of social cues about each other and could neither communicate verbally nor nonverbally. They played two games: (1) Single Game, where other players were invisible, and (2) Joint Game, where each player could see players' positions in a local radius around himself/herself. We found that individuals approached their neighbours spontaneously if their positions were visible, leading to less spatial dispersion of the whole group compared to moving alone.

Our computer-based multi-participant game empirically assessed how competitive versus neutral conditions influenced the reward-maximising behaviour of 200 undergraduate students functioning in ten-person groups - each playing two games (1 neutral and 1 competitive), their perceived pay satisfaction as well as perceived stress levels and sense of calmness within the games' task to search for coins. Participants were represented by black dots moving on a virtual playground. Results showed that competition led to reward-maximising but fellow group member disadvantaging behaviour, and all participants experienced lower pay satisfaction, higher stress levels and less calmness. We conclude that short-term behavioural consequences of positive individual competitive behaviour were gained at the above-mentioned potential long-term negative costs for all group members. This implies group paradigms aimed at sustainability should avoid introducing competitive factors that at best result in short-lived gains and at worst cause widespread dissatisfaction, stress and a pervasive lack of calmness.

Objective: We investigate antidepressant effects of an adapted group-based CORDIAL program in clinical routine care. Methods: During 2013 and 2017, 51 outpatients with mild dementia (45% female, mean age 72.4 years, 67% Alzheimer’s dementia, mean MMST 24.8) periodically received a modified CORDIAL group treatment as part of our regular outpatient care. Treatment comprised 10 bi-weekly sessions, partly involving caregivers. Systematic pre- and post-treatment assessments of clinical routine data were evaluated retrospectively (median time-interval of 6.6 months). Results: Depressive symptoms as measured by the Geriatric Depression Scale significantly decreased over time (p = 0.007, Cohen’s d = 0.39), and irrespective of gender. Patients with longer disease duration before treatment start showed significantly higher initial levels of depressive symptoms (p = 0.044), followed by a reduction to a level of those with shorter disease duration (ns). Most secondary outcomes (cognitive symptoms, disease severity, quality of life, caregiver burden) remained unchanged (ns), while competence in activities of daily living declined from pre- to post-measurement (p = 0.033). Conclusion: A group-based CORDIAL treatment is feasible in a clinical routine setting and demonstrated antidepressant effects comparable to those of the individual treatment design, further suggesting its implementation in regular care. Future trials might also investigate its potentially preventive effects by reducing depressive symptoms in pre-dementia stages, even at a subsyndromal level."],["dc.identifier.doi","10.3233/JAD-220578"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/118184"],["dc.notes.intern","DOI-Import GROB-621"],["dc.relation.eissn","1875-8908"],["dc.relation.issn","1387-2877"],["dc.title","Antidepressant Effects of a Multimodal Group Therapy Program for Mild Dementia: A Retrospective Evaluation of Clinical Routine Data"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
