Filter by:The present study is a pilot single-blind randomized controlled therapy study. Its aim is to assess the efficacy of an emotion-focussed form of Cognitive behavior Therapy that focusses on emotional processes that are involved in the formation and maintenance of delusions such as emotional stability, emotion regulation and self-esteem.
Primary study: This study is a single-site, double-blind, randomized, controlled clinical trial to compare an evidence-based structured program of 30-35 hours of on-line cognitive and social cognitive training exercises performed over 16 weeks (~2 hours per week), delivered with an innovative digital app which provides users with a motivation coach to set personalized goals and with secure social networking for peer support, "PRIME" ; vs. 2) A control condition of computer games, encouraged at ~2 hours per week over 16 weeks, delivered with "PRIME". Unblinded Cognitive Training Sub-Study: Participants who were randomized to the computer games arm of the trial may be offered access to the active cognitive training at the end of their 6 month follow up appointments, if they still meet inclusion criteria. PRIME Super Users Sub-Study: Participants who have provided all follow up data to the initial study, including those who are currently enrolled in the Unblinded Cognitive Training sub-study, may be offered continued participation in the PRIME community as super-users.
Schizophrenia (SZ) is a chronic, severe disease resulting in a misperception of reality, major social withdrawal and cognitive disturbances. Executive dysfunctions are widely considered as primary determinants of functional outcome. However, classic neuropsychological executive function measures poorly represent patients' functional outcome and seem inappropriate to evaluate the real-world functional impact of the disease. In this perspective, Shallice and Burgess have developed for brain-damaged patients, the Multiple Errands Test (MET) allowing to assess planning, adaptation, problem solving and mental flexibility in real life settings, thus better capturing day-to-day abilities and including contextual (social, perceptive) influences. Setting the assessment outside the laboratory can help to identify subtle executive impairment not systematically expressed in standard care conditions and consequently improve the future care solutions. MET is based on the Supervisory Attentional System model of executive functioning and attention control that specifies how thought and action schema become activated or suppressed for routine and non-routine circumstances. MET has been designed to measure real-world executive performance confronting the participants to unpredictable affordances and interpersonal interactions while planning and problem solving. Patients are asked to accomplish several tasks of variable complexity in an unknown commercial district. Severals rules must be respected and thus an action plan, strategy formulation, time and space management with very little assistance of the examiner are required. Most of the studies involving MET were conceived for patients with acquired brain damage. LeThiec offered an extensive protocol with the initial scoring system (in terms of inefficiencies, rule breaks, interpretation failures and task execution failures). Simplified versions of MET were also suggested to be more suitable in hospital settings. Only one study was done in SZ including a single patient, it is therefore difficult to draw conclusions about clinical utility in SZ. To date, no other studies investigated the suitability of MET in patients with psychosis, while executive impairment is well documented in this population The investigators hypothesized that the Multiple Errands Test (MET), an ecological assessment of executive function has a better ability to measure everyday adaptative functioning SZ, compared to conventional EF assessment methods.
The study is a retrospective cohort study of adults with schizophrenia that will compare outcomes of new users of alternative psychotropic medication strategies using 10 years of Medicaid data. The primary comparative effectiveness analyses will focus on subgroups of patients with schizophrenia facing common clinical situations.
A one year, open-label, study to evaluate the safety and tolerability of risperidone implants as a maintenance treatment in patients with schizophrenia
Prevalence of somatic comorbidities in psychiatric patients hospitalized in Psychiatric hospital or treated ambulatory or in daily hospital. Comparison of prevalence of somatic comorbidities in psychiatric patients population and the general Croatian population.
The purpose of this study is to estimate the proportion of participants fulfilling criteria for symptomatic remission following a transition to 12 months treatment with flexible-dose paliperidone palmitate 3 month formulation (PP3M) in participants with schizophrenia previously adequately treated with paliperidone palmitate 1 month formulation (PP1M) for at least 4 months.
Impairments in plasticity and working memory in schizophrenia have been hypothesized to reflect dysfunction at the N-methyl-D-aspartate glutamate receptor (NMDAR). However, the specific mechanisms through which the NMDAR is involved in working memory versus plasticity differ. Towards gaining a deeper understanding of how NMDAR signaling relates to individual cognitive functions in healthy adults and patients with schizophrenia, the investigators used a single dose of d-cycloserine (DCS) as an experimental probe to examine the effects of enhancing NMDAR signaling on plasticity versus working memory in healthy adults and individuals with schizophrenia.
The purpose of this study was to assess the safety and tolerability of injections of RBP-7000 in subjects with stable schizophrenia
The main purpose of the study is to examine to which extent abnormalities in the dynamics of neural activities observed in patients with psychosis is related to difficulties at ordering simple visual stimuli and/or personal events.
