ABSTRACT
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.
ABSTRACT
Objective:By analyzing the norm data results of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-Ⅳ) in China,to prove the validity of the procedure and methods during the norming development.Methods:The whole process of the revision of WAIS-Ⅳ,the development of computer-assisted system and norm sampling plan,were introduced in more detail,and the distribution of actual norm data of 1757 cases was analyzed.Results:For area distribution,compared with planned sampling number,the number from North and Northeast China was statistically significant different (x2 =78.02,P ＜0.01).For age stages distribution,most of cases conformed to the requirements of sampling,except that some cases including high-level educational cases aged 16-17 years and above 65 years,and low-level educational cases aged 30-34 years were less than the planned sampling number.For gender distribution,male subjects were more,but there was no statistically significant difference between male and female subjects (x2 =228,P =0.131).For educational degree distribution,the sampling conformed to the requirements of sampling plan (x2 =2.74,P =0.603).For occupation,resident years and registered permanent residence,and the sample was basically representative.Conclusion:The process of the revision of the Chinese version of WAIS-Ⅳ is appropriate,and actual norm sampling basically conforms to planned sample distribution,providing the sufficient representativeness and reliability for national norm data of WAIS-Ⅳ.
ABSTRACT
Objective:To understand the characteristics of the callers with the diagnosis of mental disorders called Beijing Psychological Crisis Hotline for help,in order to provide specific psychological intervention services for them in future.Methods:From December 2002 to December 2008,24217 different callers'data collected from a computer-based operating system of the Beijing Psychological Crisis Hotline were analyzed.According to their self-reported of having the diagnoses of mental disorder or not,the callers were divided into the ones with diagnosis (n=6516)and the ones without diagnosis (n =17701).The callers'demographic characteristics,their main counseling problems and the suicide-related factors in the two groups were compared.Results:The top five main counseling problems in the group with diagnosis were mental problems,the mental illness related knowledge,the problems of family relationships,working problems and interpersonal problems.Mental problem ranked first in both groups.Compared to the group without diagnosis,the diagnosed ones were more likely to be found in such group of people as women,aged between 20 -29 and 30 -44,having 10 or more years of education and the unem-ployed.The results of the assessments of 11 suicide-related risk factors showed that callers with diagnoses had higher prevalence of most suicide-related factors than those in the other group(P <0.001 or 0.05),which included suicidal intention and behavior while calling,history of attempted suicide,severe depressive symptoms,severe physi-cal illness,history of being abused,afraid of being attacked,suicidal history of relatives or associates,severe of hopeless.Conclusion:The hotline counselors should be aware of the necessity of assessing the severity of depres-sion and other suicide-related factors for the callers with mental disorder diagnoses before providing any psychologi-cal intervention.Moreover,except for providing interventions on the callers'psychiatric problems,the hotline coun-selors should also identify and help to deal with the stress events in their lives.
ABSTRACT
Objective:To compare the results of two different measures assessing prospective memory (PM) in elderly schizophrenia,and explore their diagnostic validity.Methods:Fifty patients who were diagnosed as schiz-ophrenia according to the criteria of Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-Ⅳ)and 50 normal elderly people were enrolled in the study.Laboratory paradigm prospective memory task and the Chinese version of the Cambridge prospective memory Test (C-CAMPROMPT)were administered to measure thelevel of EBPM and TBPM.The Wechsler Adult Intelligence Scale-Fourth Edition,Continuous Performance Test-I-dentical Pairs were used to evaluate IQ and attention.Results:Whether in the laboratory paradigm or C-CAM-PROMPT,schizophrenia group performed worse than normal controls on PM total scores[7(0,16)vs.12(0,16),14 (4,34)vs.25(11,36)],EBPM[3(0,8)vs.6(0,8),7(2,16)vs.14(4,18)]and TBPM [3(0,8)vs.6(0,8),6(2,18) vs.12(4,18)],and patients had comparable performances in PM subtypes[-1.0(-2.2,1.0)vs. -1.0(-2.1, 0.8),-1.9(-3.4,0.8)vs. -1.8(-2.9,1.6)].In the C-CAMPROMPT,the scores of EBPM and TBPM were negatively related to age(r=-0.36 --0.40,P<0.001 ),but there was no significant relationship between PM performance and age in the laboratory paradigm task.The area under ROC curve of the laboratory paradigm and C-CAMPROMPT were 0.73 and 0.85.While 8 and 19 as the cut off value,the sensitivity were 0.60 and 0.74,and the specificity were 0.76 and 0.90,respectively.Conclusion:The two measures have confirmed that the elderly schizophrenia have comparable performances in EBPM and TBPM.Both the C-CAMPROMPT and the laboratory paradigm have moderate level of diagnostic validity,but the former is slightly higher and more susceptible to aging.
ABSTRACT
@#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.
ABSTRACT
Objective To explore cognitive change in schizophrenic patients with concomitant metabolism syndrome,and to provide theory basis for early intervention and treatment.Methods According to inclusion standard,56 schizophrenic inpatients with metabolism syndrome and 56 schizophrenic inpatients without metabolism syndrome were included.The matrics consensus cognitive battery(MCCB),stroop test,digit span,UPSA-B were used to assess the cognitive function.Results There were significant differences for test scores of symbol coding subtest,verbal memory subtest,digit sequence subtest,Maze subtest,continue performance among MCCB between schizophrenic patients with and without metabolism syndrome(27.07±10.46 vs 32.18±12.12,16.04±5.07 vs18.71±6.02,13.39±5.18 vs 15.79±5.48,1.38±0.66 vs 1.7±0.68,all P＜0.05),as well as stroop test and digit span test(31.14±11.68 vs 36.57±13.32,13.77±3.64 vs 15.82±4.38,P＜0.05 for both).Conclusion The schizophrenic patients with metabolism syndrome have severer cognitive impairment than those without metabolism syndrome.
ABSTRACT
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.
