Objective:To explore the central mechanism of working memory impairments experienced by patients with schizophrenia.Methods:Using block-design,ten normal and twenty patients with schizophrenia perform digital recognition(remember two or five digitals simultaneous and make judgment about whether the digital presented latter is that appeared before)and direction judgment of arrows(toward to left or right)while proceeding blood-oxygen level dependent contrast functional magnetic resonance imaging(BOLD-fMRI).Results:On the condition of same cognitive load,abnormal activation of basal ganglia occurred in schizophrenics.Comparing to normal control,patients with schizophrenia exhibited a tendency of more activation in dorsolateral prefrontal cortex.Conclusion:Abnormal activity of basal ganglia and dorsolateral prefrontal cortex may be the critical cause of working memory deficit experienced by patients with schizophrenia.

Objective:To explore the utility of psychiatric service of clients having online counseling for anxiety or depression. Methods:The anxiety group was consisted of clients (n=107) who were positive in the Self-rating Anxiety Scale (SAS) online, similarly the depression group was consisted of clients (n=102) with positive results in Self-rating Depression Scale (SDS) online screening. Both groups were investigated with the questionnaires include issues related to the clinical features, diagnostic categories and treatment vs professional advice on clients. Results:In the anxiety group (male 69/female 38), the average age was 28+8, 88(82.2%) with more than 15 years education. In the depression group (male 57 vs. female 45), the average age was 29+8, 81(79.4%) with more than 15 years education. None was illiterate. For the age, sex, education and occupation, there was no significant difference between the two groups. 81(79.4%) clients in the anxiety group and 89(87.2%) clients in the depression group were advised to visit psychiatrists or psychologists. A few were advised to counseling online only and there was no significant difference between the two groups. The main diagnoses were mood disorders, neurosis and psychogenic disorders. Actually, 29(27.1%) in the anxiety group were treated with anxiolitics, 31(30.2%) in the depression group were treated with antidepressants at local clinics. Conclusion:Most of the clients should visit psychiatrists or psychologists, and a few may have their psychological counseling online only. Health education and psychological counseling online may be helpful to improve the rate of diagnosis and treatment of mental disorders in local clinics.

Objective To explore the relationship between prospective memory (PM), retrospective memory (RM) and social function in old patients with schizophrenia. Methods 54 old patients with schizophrenia and 54 healthy controls were evaluated with logical memory (LM)IQ, LMIIQ of Wechsler Memory Scale-Fourth Edition (WMS-IV), Chinese Cambridge Prospective Memory Test (C-CAMPROMPT), University of California at San Diego (UCSD) Performance- based Skills Assessment- brief (UPSA- B), and Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV). Results The scores of LMIQ, LMIIQ, event-based prospective memory (EBPM), time-based prospective memory (TBPM), IQ, and UPSA-B were poorer in the patients than in the controls (P<0.001). The score of UPSA-B was positively correlated with LMIQ (r=0.524, P<0.001), LMIIQ (r=0.427, P<0.001), EBPM (r=0.437, P<0.001), TBPM (r=0.479, P<0.001) and IQ (r=0.709, P<0.001). Linear regression analysis indicated that TBPM (β=0.811, P=0.007), IQ (β=0.610, P<0.001) were contributing factors for the score of UPSA-B. Conclusion Schizophrenics may complicate the impairment of PM and RM, and the former may be independent fluence to their social function.

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.

Objectives To compare prospective memory (PM) deficits with retrospective memory (RM) deficits and to explore the correlation between PM and RM in chronic schizophrenia. Methods Fifty chronic schizophrenia pa?tients and fifty healthy controls were recruited. The PM performance [event-based PM (EBPM) and time-based PM (TB?PM)] were evaluated by the Chinese version of the Cambridge Prospective Memory Test (C-CAMPROMPT); working memory (WM) was evaluated by the digital span subtest (DS);immediate auditory logical memory (IALM), delayed audito?ry logical memory (DALM), immediate visual reproduction memory (IVRM) and delayed visual reproduction memory (DVRM) were evaluated by the logical memory and visual reproduction subtest. The score of each test was transformed to comparable standard score. Results Patients performed significantly worse on EBPM [(7.9 ± 3.4) vs. (13.7 ± 2.9)], TBPM [(6.9±3.6) vs. (13.0±3.2)], DS [sequence:(5.8±2.0) vs. (7.5±2.2);backward:(6.5±1.9) vs. (8.2±2.8)], IALM [(8.3±3.1) vs. (11.9 ± 2.5)], DALM [(7.4 ± 3.7) vs. (11.8 ± 2.6)], IVRM [(8.0 ± 2.7) vs. (11.2 ± 3.8)], and DVRM [(7.7 ± 3.5) vs. (10.8 ± 2.7)] scores than controls (P<0.05). The extent of deficits of EBPM and TBPM were greater than those of DS (sequence and backward), IALM, DALM, IVRM and DVRM (P<0.05), but not DALM (P>0.05). The performance of PM in chronic schizophrenia was significantly related to DS (sequence and backward), IALM, DALM and DVRM (P<0.05), but not IVRM (P=0.155). Conclusion:There are greater prospective memory deficits than retrospective memory deficits in chron?ic schizophrenia and the prospective memory deficits are correlated with the retrospective memory deficits in chronic schizophrenia.

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.

Objective To explore the reliability and validity of the computerized Chinese version of Cambridge Prospective Memory Test (C-CAMPROMPT) for assessment of prospective memory (PM) in chronic schizophrenia patients. Methods 50 patients and 50 healthy controls formed the study sample. PM performance was measured with computerized C-CAMPROMPT, while the Wechsler Adult Memory Scale-Forth Edition (WMS-IV), Wisconsin Card Sorting Test (WCST) and Category Fluency Test (CFT) were administered to assess logical memory (LM), visual representation (VR), executive function and processing speed. Results The test- retest reliability (0.981, P<0.001), split half reliability (0.627, P<0.001) and internal consistency reliability (0.742) of C-CAMPROMPT were satisfied. The scores of C-CAMPROMPT and its subtest in schizophrenia were lower than that in healthy control (P<0.001). The performance of PM in patients with schizophrenia closely related to the scores of LM, VR, WCST-CC and CFT (r=0.34~0.89, P<0.05). The sensitivity (86%) and specificity (92%) of the scale were satisfied. Factor analysis extracted 2 factors. Conclusion The computerized C-CAMPROMPT shows a good reliability and validity for assessment of PM function in chronic schizophrenia, and is a sensitive, adaptable, stable instrument.

Objective To develop Prospective Memory Test and explore its reliability and validity in normal and schizophrenic population. Methods According to the structure of prospective memory, Prospective Memory Test was developed based on the previous researches. 40 inpatients with schizophrenia and 30 healthy subjects were assessed with Prospective Memory Test and Wechsler Memory Scale-Fourth Edition, Chinese (WMS-Ⅳ). Results Factor analysis extracted 2 main factors, named time-based prospective memory (TBPM) and event-based prospective memory (EBPM), including 10 items. The average score of Prospective Memory Test was lower in the patients than in the healthy controls by 1~2 standard deviations (P<0.001). Discriminant analysis showed that the specificity, sensitivity, and diagnostic consistency were 93.3%, 72.5% and 81.4%, respectively. Prospective Memory Test scores and two subtest scores positively correlated with total score of WMS-Ⅳ (r=0.44~0.53, P<0.001). The Cronbach's α among all the items was 0.76, and was 0.68 in the TBPM and 0.59 in the EBPM. Split-half reliability of the scale was 0.65 (P<0.001). Conclusion The reliability and validity of Prospective Memory Test are acceptable for schizophrenics.
