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.

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 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.
