Preferences for family involvement among veterans in treatment for schizophrenia.

Objective: Examine preferences for family involvement in psychiatric care in a large, representative sample of veterans in treatment for schizophrenia.

Method: Veterans with schizophrenia or schizoaffective disorder ( = 801) completed an assessment that included questions about demographic and clinical characteristics, status of family support, and preference for family involvement in their psychiatric care. Open-ended items were independently coded by two raters and categorized; Cohen's kappa was calculated for each category.

White matter abnormalities in schizophrenia and schizotypal personality disorder.

Prior diffusion tensor imaging (DTI) studies examining schizotypal personality disorder (SPD) and schizophrenia, separately have shown that compared with healthy controls (HCs), patients show frontotemporal white matter (WM) abnormalities. This is the first DTI study to directly compare WM tract coherence with tractography and fractional anisotropy (FA) across the schizophrenia spectrum in a large sample of demographically matched HCs (n = 55), medication-naive SPD patients (n = 49), and unmedicated/never-medicated schizophrenia patients (n = 22) to determine whether (a) frontal-striatal-temporal WM tract abnormalities in schizophrenia are similar to, or distinct from those observed in SPD; and (b) WM tract abnormalities are associated with clinical symptom severity indicating a common underlying pathology across the spectrum. Compared with both the HC and SPD groups, schizophrenia patients showed WM abnormalities, as indexed by lower FA in the temporal lobe (inferior longitudinal fasciculus) and cingulum regions.

Implementation of evidence-based employment services in specialty mental health.

Objective: Study a quality improvement approach for implementing evidence-based employment services at specialty mental health clinics.

Data Sources/study Setting: Semistructured interviews with clinicians and administrators before, during, and after implementation. Qualitative field notes, structured baseline and follow-up interviews with patients, semistructured interviews with patients after implementation, and administrative data.

Schizoid personality disorder.

Schizoid personality disorder (ScPD) is one of the "odd cluster" or "cluster A" personality disorders in DSM-IV. In the present article, the authors review information pertaining to the psychometric characteristics of ScPD as gleaned from a search of relevant publications as well as from databases of personality disorder study groups. Comparatively little evidence exists for the validity and reliability of ScPD as a separate, multifaceted personality disorder.

Larger putamen size in antipsychotic-naïve individuals with schizotypal personality disorder.

Objective: To (a) compare the size of the dorsal and ventral striatum (caudate and putamen) in a large sample of antipsychotic-naïve individuals with schizotypal personality disorder (SPD) and healthy control participants; (b) examine symptom correlates of striatal size in SPD.

Methods: The left and right caudate and putamen were hand-traced on structural MRI at five dorsal to ventral slice levels in 76 SPD and 148 healthy control participants. A Group×Region (caudate, putamen)×Slice (1-5: ventral, 2, 3, 4, dorsal)×Hemisphere (left, right) mixed-model MANOVA was conducted on size relative to whole brain.
