Mistrust of outreach workers and lack of confidence in available services among individuals who are chronically street homeless.

This qualitative study explored how individuals who are homeless perceive outreach practices and available services. Interviews were conducted with 24 people who had been homeless for >/=1 year and who consistently resided on the streets of west midtown, Manhattan, New York. Reasons why these individuals refuse services include a pervasive mistrust of outreach workers and the agencies that employ them, as well as a prominent lack of confidence in available services. The findings suggest a need for an approach to outreach that incorporates giving individualized attention from outreach workers, using an empathetic listening approach, minimizing stereotyping, providing greater choices, and employing formerly homeless people as outreach workers.

Neurological soft signs and minor physical anomalies in patients with schizophrenia and related disorders, their first-degree biological relatives, and non-psychiatric controls.

BACKGROUND: Subtle neurological impairments and inconsequential minor anomalies of the face and limbs are manifestations of neurodevelopmental and ontogenic abnormalities that are consistently found at higher rates in individuals with schizophrenia compared to healthy controls. Limited research has been conducted on these traits among biological relatives of patients with schizophrenia. This study hypothesized that the mean NSS score and the mean MPA score would be greater in patients than controls and that first-degree relatives would have intermediate scores. Furthermore, it was hypothesized that NSS scores and MPA scores would not be correlated. This study also explored correlations between patients' NSS and MPA scores and their relatives' respective scores and sought to replicate the finding that NSS are associated with negative and disorganized symptoms of schizophrenia, whereas MPAs are not. METHODS: Patients with schizophrenia and related psychotic disorders (n=73), first-degree relatives (n=44), and non-psychiatric controls (n=54) were assessed. Measures included the Neurological Evaluation Scale, a structured examination for MPAs, and the Positive and Negative Syndrome Scale in patients. Analyses accounted for clustering within families. RESULTS: Both NSS and MPAs were greater in patients than controls, and first-degree relatives had intermediate scores. Furthermore, NSS and MPA scores were independent in all three groups. Correlations were found between patients' and their relatives' scores on one NES subscale (sensory integration) and total MPA score and several MPA regions (eyes, ears, and hands). This study replicated previous findings that in patients with schizophrenia, NSS are associated with negative, disorganized, and other domains of symptoms. Associations between MPAs and symptoms were sparse and inconsistent. CONCLUSION: These findings suggest that NSS and MPAs represent two quite distinct markers of risk for schizophrenia that may stem from genetic factors, as well as from environmental/developmental influences. Future research on multivariable risk prediction models may benefit from the use of somewhat independent risk markers or endophenotypes.

Facial measurement differences between patients with schizophrenia and non-psychiatric controls.

OBJECTIVE: Several previous reports suggest that facial measurements in patients with schizophrenia differ from those of non-psychiatric controls. Because the face and brain develop in concert from the same ectodermal tissue, the study of quantitative craniofacial abnormalities may give clues to genetic and/or environmental factors predisposing to schizophrenia. Using a predominantly African American sample, the present research question was two-fold: (1) Do patients differ from controls in terms of a number of specific facial measurements?, and (2) Does cluster analysis based on these facial measurements reveal distinct facial morphologies that significantly discriminate patients from controls? METHOD: Facial dimensions were measured in 73 patients with schizophrenia and related psychotic disorders (42 males and 31 females) and 69 non-psychiatric controls (35 males and 34 females) using a 25-cm head and neck caliper. Due to differences in facial dimensions by gender, separate independent samples Student's t-tests and logistic regression analyses were employed to discern differences in facial measures between the patient and control groups in women and men. Findings were further explored using cluster analysis. Given an association between age and some facial dimensions, the effect of age was controlled. RESULTS: In unadjusted bivariate tests, female patients differed from female controls on several facial dimensions, though male patients did not differ significantly from male controls for any facial measure. Controlling for age using logistic regression, female patients had a greater mid-facial depth (tragus-subnasale) compared to female controls; male patients had lesser upper facial (trichion-glabella) and lower facial (subnasale-gnathion) heights compared to male controls. Among females, cluster analysis revealed two facial morphologies that significantly discriminated patients from controls, though this finding was not evident when employing further cluster analyses using secondary distance measures. When the sample was restricted to African Americans, results were similar and consistent. CONCLUSIONS: These findings indicate that, in a predominantly African American sample, some facial measurements differ between patients with schizophrenia and non-psychiatric controls, and these differences appear to be gender-specific. Further research on gender-specific quantitative craniofacial measurement differences between cases and controls could suggest gender-specific differences in embryologic/fetal neurodevelopmental processes underpinning schizophrenia.

Associations between olfactory identification and verbal memory in patients with schizophrenia, first-degree relatives, and non-psychiatric controls.

OBJECTIVE: Olfactory identification deficits and verbal memory impairments may represent trait markers for schizophrenia. The aims of this study were to: (1) assess olfactory identification in patients, first-degree relatives, and non-psychiatric controls, (2) determine differences in verbal memory functioning in these three groups, and (3) study correlations between olfactory identification and three specific verbal memory domains. METHOD: A total of 106 participants-41 patients with schizophrenia or related disorders, 27 relatives, and 38 controls-were assessed with the University of Pennsylvania Smell Identification Test (UPSIT) and the Wechsler Memory Scale-Third Edition. Linear mixed models, accounting for clustering within families and relevant covariates, were used to compare scores across groups and to examine associations between olfactory identification ability and the three verbal memory domains. RESULTS: A group effect was apparent for all four measures, and relatives scored midway between patients and controls on all three memory domains. UPSIT scores were significantly correlated with all three forms of verbal memory. Age, verbal working memory, and auditory recognition delayed memory were independently predictive of UPSIT scores. CONCLUSIONS: Impairments in olfactory identification and verbal memory appear to represent two correlated risk markers for schizophrenia, and frontal-temporal deficits likely account for both impairments.
