Reliability and validity of the Chinese version of the multidimensional anxiety scale for children among Chinese secondary school students.

The objective of the current study was to develop a Chinese translation of the Multidimensional Anxiety Scale for Children (MASC) [March (1997) Multidimensional anxiety scale for children: Technical manual, Multi health systems, Toronto, ON], and to evaluate its reliability and validity. The original version of the MASC was translated into Chinese (MASC-C) and administered to 1,538 Chinese adolescents between the ages of 14 and 19. In comparison to the American normative sample [March (1997) Multidimensional anxiety scale for children: Technical manual, Multi health systems, Toronto, ON], Chinese adolescents reported significantly higher scores on the subscales of social anxiety and separation anxiety. Girls reported higher levels of anxiety on all subscales than males. Participants between the ages of 16 and 19 reported higher scores on the physical symptoms and harm avoidance subscales. The MASC-C exhibited strong internal consistency (Cronbach's alpha coefficient was 0.91 and the mean inter-item correlation coefficient was 0.20) and moderate test-retest reliability (intra-class correlation coefficient was 0.84 over a one-month interval). MASC scores inter-correlated a small to moderate degree with measures assessing negative life events and depressive symptoms indicating acceptable convergent validity. The results of confirmatory factor analyses indicated that the four-factor structure of the MASC was suitable for the Chinese sample. The four factor structure was also invariant across sex and age. As the Chinese translation of the MASC indicated high levels of reliability and validity, the MASC-C is appropriate for assessing anxiety in Chinese adolescents.

Intratask and intertask asymmetry analysis of motor function.

Ample evidence from functional magnetic resonance imaging studies has demonstrated functional brain asymmetries in the motor cortex and cerebellum within the task of finger-to-thumb (intratask), but the asymmetries across left and right hand-performed tasks of finger-to-thumb (intertask) are little known. Here, we found that intratask evoked asymmetry responses in the motor cortex and cerebellum, and interestingly in the Extra-Nuclear and insula. Intertask comparisons between left and right hand-activated images and between the asymmetries of intratasks of left and right hand, however, revealed distinct lateralization responses in the temporal cortex, extranuclear, parahippocampal gyrus, cingulate gyrus and prominently in basal ganglia. These results suggest that multiple aspects of functional asymmetries in motor organization are reflected in specific brain regions.

Reliability and factorial validity of the Observer Alexithymia Scale-Chinese translation.

The purpose of the present study was to develop a Chinese translation of the Observer Alexithymia Scale (OAS-C) and evaluate its reliability and factorial validity. The original English-version of the Observer Alexithymia Scale (OAS) was translated into Chinese and given to 468 Chinese undergraduate students. Students were asked to rate a person (other than themselves) whom they knew well (e.g., a parent, sibling, another relative, or friend). We evaluated internal consistency, test-retest and inter-rater reliability, and factorial validity. Average OAS-C scores were slightly higher than, but comparable to, OAS scores in the normative samples (English-speaking/nonclinical). The OAS-C showed adequate internal consistency (Cronbach's alpha coefficient was 0.84, and the mean inter-item correlation coefficient was 0.14), good stability (test-retest reliability with a 2-week interval was 0.90), and inter-rater reliability (intra-class correlation coefficient was 0.78). Moreover, the OAS five-factor model (Distant, Uninsightful, Somatizing, Humorless, and Rigid) was confirmed: incremental fit index=0.905, comparative fit index=0.904, and root mean square error of approximation=0.086; each represented an adequate model fit. The OAS-C appears to be a reliable and valid observer-rated alexithymia measure. We recommend that researchers collect both self- and observer-rated alexithymia data and, when possible, obtain observer reports from more than one person.

Positive and negative symptom profile schizophrenia and abnormalities in the P300 component of the event-related potential: a longitudinal controlled study.

The relationship between symptoms of schizophrenia and abnormalities in the P300 component of the event-related potential (ERP) was investigated in 22 and 27 patients diagnosed with positive and negative profile schizophrenia, respectively. The Positive and Negative Syndrome Scale (PANSS) was used to characterize clinical symptoms. A group of 30 normal controls were also studied. Results showed that patients with schizophrenia exhibited reduced P300 amplitudes compared with controls and that those with negative profile schizophrenia had amplitude decrements and longer latencies. These findings suggest that there are neurobiological differences between positive and negative profile schizophrenia.
