Background: Subjective response (SR) to antipsychotic medication is relevant for quality of life, adherence and recovery. Here, we evaluate (1) the extent of variation in SR in patients using a single antipsychotic; (2) the association between subjective and symptomatic response; and (3) predictors of SR.

Methods: Open-label, single treatment condition with amisulpride in 339 patients with a first episode of a schizophrenia spectrum disorder, at most minimally treated before inclusion.

Coping styles are associated with levels of subjective well-being. Negative life events and reduced subjective well-being are more prevalent in patients with psychotic disorders. The aims of the current study were to test a mediation model, with coping styles as potential mediators of the relation between negative life events and subjective well-being in patients with psychotic disorders (N = 259), and aimed to repeat the potential mediation model in patients' non-affected siblings (N = 309).

Research has found that Obsessive Compulsive Symptoms (OCS) in schizophrenia are associated with either more or less negative symptoms and either better or poorer cognitive functioning. In order to explain these contradictory results, (Lysaker et al., 2004), performed a cluster analysis resulting in 2 OCS positive (OCSpos) clusters, one with higher functioning (HF) and one with poorer functioning (PF) compared to 2 OCS negative (OCSneg) clusters.

One in five patients with a psychotic disorder has persistent low subjective well-being (SWB), which is associated with a poorer prognosis. In schizophrenia patients, personality traits are associated with SWB. The present study aims to evaluate whether neuroticism and extraversion influence SWB in patients with a psychotic disorder and healthy controls over the course of time.

Subjective well-being (SWB) is associated with treatment adherence and symptom outcome in people with psychotic disorders. Also, it is associated with psychosis susceptibility and it is partly hereditable. The SWN-20 is a widely used tool to assess subjective well-being in patients; it was also found to be suitable for assessing SWB in healthy populations.

Introduction: We present an online decision aid to involve patients with a psychotic disorder in shared decision-making concerning the selection of antipsychotic medication.

Method: Patients selected effectiveness and adverse effects criteria from the Subject's Response to Antipsychotics-34 questionnaire. Numerical data from meta-analyses, clinical trial data, receptor affinities and expert opinions were used to rank antipsychotics on each criterion.

Dopamine D2-receptor blockade by antipsychotic medication reduces psychotic symptoms, but may reduce subjective well-being. The current study aims to further explore the relation between dopamine D2-receptor affinity and subjective well-being within a large sample of patients with psychotic disorders. Patients participated in a longitudinal naturalistic cohort study: the Genetic Risk and Outcome of Psychosis (GROUP) study.
