Psychiatric Care Pathways and the Use of Coercion
The use of coercive measures in psychiatry raises ethical and clinical concerns, particularly given their potential psychological harm and long-term consequences. While most studies focus on inpatient settings, little is known about coercion applied earlier in the care pathway. This retrospective observational study included all patients ( N = 695) admitted through the psychiatric emergency department (ED) to the adult psychiatry division of Gene…
Cross-views between the roles of the therapist and the expert in forensic psychology/psychiatry
Forensic psychology/psychiatry seems particularly subject to ethical tensions, as it involves not only the expert-evaluee or therapist-patient relationships, but also the judicial authorities. This exploratory study aims to identify the professional roles—namely the identity and posture—of both the expert and the therapist within the medico-legal field, with a view to uncovering potential ethical tensions that may arise in the transition from one…
Effort-based decision making in psychopathology
0.01). Altered effort allocation patterns were marked by reduced effort exertion across increasing reward and probability conditions, with schizophrenia spectrum disorders showing the most pronounced deficits. The most robust moderators were the number of probability conditions, ethnicity, gender, and the severity of positive and negative symptoms. A narrative synthesis of computational modeling studies indicated that maladaptive EBDM may reflect…
Treatment without consent in adult psychiatry inpatient units
Women suffering from psychosis are more at risk of receiving involuntary and repeated medication. The risk of deterioration in psychosocial functioning or behavioral disorganization seems to be the main argument for this coercive measure. Future studies should focus on the patient's perception of this coercion to prevent it and improve adherence to care. Follow-up after discharge might be useful to evaluate a long-term benefit
European Validation of the Self-Evaluation of Negative Symptoms (SNS)
In a large European multicentric sample, this study demonstrated that the SNS has: (1) good psychometric properties with good convergent and divergent validities; (2) a five-factor latent structure; (3) an association with patients' functional outcome; and (4) the capacity to identify subjects with negative symptoms that is close to the BNSS and superior to the PANSS negative subscale
Negative symptoms in alcohol use disorder
Negative symptoms as conceptualized for schizophrenia are prevalent in patients with AUD and associated with the severity of AUD. More specifically, severity of AUD correlates with diminished motivation and pleasure, highlighting the importance of disturbances in motivational functions in AUD. This is further supported by the correlation between negative symptoms and craving, a hallmark of AUD. Taken together, our findings suggest that negative s…
Suicide in psychiatry and medical liability
Impact of the Covid-19 Pandemic on Psychiatric Admissions to a Large Swiss Emergency Department
The coronavirus disease 2019 (COVID-19) pandemic is a public health emergency with profound mental health consequences. The psychiatric emergency department (ED) plays a key role during this mental health crisis. This study aimed to investigate differences in admissions at a Swiss psychiatric ED from 1 April to 15 May during a "pandemic-free" period in 2016 and a "during-pandemic" period in 2020. The study included 579 consultations at psychiatri…
Loss Aversion and Risk Aversion in Non-Clinical Negative Symptoms and Hypomania
In the field of behavioral decision-making, "loss aversion" is a behavioral phenomenon in which individuals show a higher sensitivity to potential losses than to gains. Conversely, "risk averse" individuals have an enhanced sensitivity/aversion to options with uncertain consequences. Here we examine whether hypomania or negative symptoms predict the degree of these choice biases. We chose to study these two symptom dimensions because they present…
