Objective: To develop the mental health knowledge questionnaire in order to know about the awareness of mental health knowledge in non-psychiatric clinicians. Methods: A sample of the 641 non-psychiatric clinicians from 2 tertiary general hospitals, 2 second-class general hospitals, and 1 community hospital were used for item analysis and internal consistency test; 38 cases were selected for the re-test interval of 2 weeks to test the test-retest reliability. And totally 99 psychiatrists finished the survey as controls. The awareness rates between the non-psychiatric and psychliatric clinicians were compared. Results: The questionnaire included 46 items and consis-ted of 6 subscales, involving anxiety, schizophrenia, depression, dyssomnia and psychological counseling, or-ganic brain disorder, and recognition for mental health service situation in general hospital The results of confirma-tory factor analysis showed that the ratio of chi-square and degree of freedom was below 3. The fitting indexes except GFI and AGFI were more than 0.90. The Cronbach's alpha coefficients ranged from 0.73 to 0.89, and test-retest Pearson correlation coefficient of reliabifity ranged from 0.59 to 0.78. Awareness rate was 47.6% in general hospital and 90.9% in psychiatric hospitals. Conclusion: The mental health knowledge questionnaire has good psychometric properties and may be applied in clinical studies.

Objective: To establish an intensity-classified Chinese facial emotion image database and provide materials for emotional researches in China. Methods: Firstly, under the guidance of professional director, 22 professional dramatic actors put up seven kinds of emotion, including anger, disgust, fear, sadness, surprise, happy and calm. The process of facial emotional performance of actors were filmed by a high-speed camera. Then we made screen captures according to the intensity of emotion performed by the actors. A total of 814 black-and-white photographs with same size and gray level were made after we removed the irrelevant parts to the facial features. Each kind of emotion contains six levels of intensity scoring from 1 to 6. Totally, 112 healthy volunteers were recruited to evaluate the emotional intensity, pleasure and arousal of all images via a visual scale ranged from 0 to 100. Results: A Chinese face emotional intensity hierarchical picture library was set up, which contained 2 sublibraries. The first library was consisted of 436 images with hierarchical emotional intensity images collected from different performers. The second one was built with 640 images, in which the hierarchical emotional intensity image was collected from same actor/actress. Both image libraries had corresponding scores for intensity, pleasure, and arousal. Furthermore, both exhibited a high degree of internal consistency in reliability analysis (with a Cronbach' s alpha value larger than 0. 9). Conclusion: The present study has established an intensity-classified Chinese facial emotion image database with good recognition degree and psychological measurement attribution, which could provide materials for emotional researches in China.

Objective To investigate the memory characteristics and related factors of patients with mental retardation. Methods 73 patients with mental retardation (patient group) and 73 normal subjects (control group) matched with the patient group were respectively tested with Wechsler Memory Scale-Fourth Edition of Chinese Version (WMS-IV). Results The scores of each subtest and composite scores of WMS-IV were significantly lower in the patient group than in the control group (P<0.01). All the composite scores positively correlated with each other in the patient group (r=0.38-0.90, P<0.01) and in the control group (r=0.31-0.94, P<0.01). Age and education level positively correlated with all the composite scores (except the Visual Working Memory Index) in the patient group (P<0.05). Conclusion The patients with mental retardation present an overall decline in memory, especially in the immediate memory. The memory function in patients is related with their ages and education levels.

Objective To investigate the intellectual characteristics and related factors for patients with mental retardation. Methods 118 patients with mental retardation and 118 normal subjects were assessed with Wechsler Adult Intelligence Scale-fourth edition of Chinese (WAIS-Ⅳ). Results The full intelligence quotient (FIQ), index and scores of subtests were significantly lower in the patients than in the controls (P<0.01), especially for those of working memory and processing speed index. The difference in percentage of significance between verbal comprehension and working memory was higher (P<0.05). The FIQ and some index of patients positively correlated with age, education level and their parents' education level (P<0.01). Conclusion The patients with mental retardation present an overall decline in intelligence,especially in the working memory and processing speed. The mental development is unbalanced in some patients, that the verbal comprehension is relatively better than working memory. The intelligence of patients with mental retardation may be related with their age, education level and their parents' education level.
