Is the repeatable battery for the assessment of neuropsychological status factor structure appropriate for inpatient psychiatry? An exploratory and higher-order analysis.
ABSTRACT The present study, utilizing a sample of inpatients with schizophrenia or schizoaffective disorder (n = 167), examined the factor structure of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Principal axis exploratory factor analysis, multiple factor extraction criteria, and higher-order factor analysis were used. Results were inconsistent with the five-factor structure of the RBANS purported in the test manual. Factor extraction criteria recommended extraction of one or two factors. Extraction of two factors resulted in a memory dimension and a less homogeneous visual perception and processing speed dimension. Higher-order analysis found that a second-order factor, representing general neurocognitive functioning, accounted for over three times the total and common variance than the two first-order factors combined. It was concluded that although the RBANS appears to be a useful measure of general neurocognitive functioning for inpatients with schizophrenia or schizoaffective disorder, clinical interpretation beyond a general factor (i.e., Total Scale score) should be done with caution in this population. Limitations of the present study and directions for future research are discussed.

ABSTRACT: The aim of this study was to investigate the characteristics of cognitive function damage in chronic schizophrenia patients with metabolic syndrome (MS); 388 patients were divided into two groups: MS group (180 people with schizophrenia and MS) and non-MS group (208 people with schizophrenia but without MS). The Positive and Negative Syndrome Scale (PANSS) and the Treatment Emergent Symptom Scale (TESS) were used to evaluate clinical symptoms and drug adverse reaction. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was used to assess cognitive function. There was no significant change in PANSS (p = 0.53) and TESS score (p = 0.26) between the MS group and the non-MS group. However, RBANS total scale score as well as attention, immediate memory, and delayed memory scores in the MS group were significantly lower than those in the non-MS group (p < 0.05). There was no significant change in visuospatial skill (p = 0.07) and language scores (p = 0.08) between the two groups. Besides, course of disease, triglyceride, antipsychotic drug type, systolic pressure, negative symptom factor, and education level showed a notable significance for cognitive function damage in turn. MS might aggravate injury of cognitive function in chronic schizophrenia, especially in immediate memory, delayed memory, and attention.The Journal of nervous and mental disease 03/2014; · 1.77 Impact Factor

ABSTRACT: This naturalistic study investigated longitudinal and cross-sectional symptomatic and neurocognitive correlates of social cognition indexed by emotion perception. Participants were 31 persons admitted to a psychiatric emergency ward due to acute psychosis. Positive and negative (i.e., affective blunting and avolition) symptoms were assessed at baseline and 12-month follow-up using the Positive and Negative Syndrome Scale. Participants completed neuropsychological assessments with alternative versions of the Repeatable Battery for the Assessment of Neuropsychological Status at baseline and at 12-month follow-up. Emotion perception was measured using the Face/Voice Emotion Test at 12-month follow-up. Correlational analyses (Spearman's rho) revealed strong and statistically significant associations between neurocognition and emotion perception (baseline r = 0.58, follow-up r = 0.43). Associations between positive symptoms and emotion perception were weak or non-existent (baseline r = 0.13, follow-up r = -0.01). Emotion perception was moderately, but not significantly, associated with affective blunting at follow-up (r = 0.33), but not at baseline (r = 0.21). The association with avolition was non-existent (baseline r = -0.05, follow-up r = 0.01). This study supports the notion that emotion perception has neurocognitive correlates. The cross-sectional trend level association with affective blunting suggests that the ability to perceive emotions might be related to, but dissociable from the ability to express emotions.Scandinavian Journal of Psychology 03/2013; · 1.29 Impact Factor
