Screening for psychosis spectrum disorders in primary care could improve early identification and reduce the duration of untreated psychosis. However, the accuracy of psychosis screening in this setting is unknown. To address this, we conducted a diagnostic accuracy study of screening for psychosis spectrum disorders in eight behavioral health services integrated into primary care clinics.

Objective: To determine whether population-based electronic screening in addition to standard targeted clinician education increases early detection of psychosis and decreases DUP, compared with clinician education alone.
The authors examine U.S.-based evidence that connects characteristics of the social environment with outcomes across the psychosis continuum, from psychotic experiences to schizophrenia.

We investigated how interactions between executive function and the largely overlooked factor of emotion regulation might relate to the incidence of symptoms of psychotic thinking in youth with 22q.

Higher rates of trauma are associated with higher psychosis risk and greater symptom frequency and severity, resulting in increased hospitalization rates and demand on outpatient primary care and mental health services. Despite an estimated 70% of individuals in the early stages of psychosis reporting a history of experiencing traumatic events, trauma effects (post-traumatic anxiety or depressive symptoms) are often overlooked in psychosis treatment and current interventions typically do not target commonly comorbid post-traumatic stress symptoms.

Aim: Duration of untreated psychosis, or the time between onset of psychosis symptoms and accurate diagnosis and treatment, is a significant predictor of both initial treatment response and long-term outcomes. As such, efforts to improve rapid identification are key. Because early signs of psychosis commonly emerge in adolescence, schools have the potential to play an important role in the identification of psychosis-spectrum disorders.

Individuals with chromosome 22q11.2 deletion syndrome (22q) represent one group of special needs youth who are at increased risk for bullying due to co-occurring genetically-mediated developmental, physical, and learning difficulties.
View Article and Find Full Text PDFApathy is a relatively common psychiatric syndrome in HIV infection, but little is known about its neural correlates. In the present study, we examined the associations between apathy and diffusion tensor imaging (DTI) indices in key frontal white matter regions in the thalamocorticostriatal circuit, which has been implicated in the expression of apathy. Nineteen participants with HIV infection and 19 demographically comparable seronegative comparison subjects completed the Apathy subscale of the Frontal Systems Behavioral Scale as a part of a comprehensive neuropsychiatric research evaluation.

A delayed match-to-sample task was modified wherein task-irrelevant facial distracters were presented early and briefly during the rehearsal of pseudoword memoranda that varied incrementally in load size (1, 2, or 3 syllables). Facial distracters displayed happy, sad, or emotionally neutral expressions.

Methods: Four hundred individuals with MA use disorders within 18months of evaluation and 355 non-MA using comparison subjects completed a comprehensive neuropsychiatric research battery, including self-report measures of everyday functioning.
Results: In logistic regression models adjusting for potential confounds, lifetime diagnoses of ADHD as determined by a structured clinical interview were significantly more prevalent among the MA participants (21%) versus comparison subjects (6%), particularly the hyperactive and combined subtypes.
As parametric cognitive models become more commonly used to measure individual differences, the construct validity of the interpretation of individual model parameters needs to be well established. The validity of the interpretation of 2 parameters of a formal model of the Continuous Recognition Memory Test (CRMT) was investigated in 2 experiments. The 1st study found that manipulating the percentage of trials on the CRMT for which degraded pseudowords were presented altered the model's stimulus encoding parameter but not the working memory displacement parameter.

However, it is unclear how distraction caused by perception of faces interacts with load-related performance. We developed a modified version of the delayed match-to-sample task wherein task-irrelevant facial distracters were presented early in the rehearsal of pseudoword memoranda that varied incrementally in load size (1-syllable, 2-syllables, or 3-syllables).
