Most studies on psychotic-like experiences in the non-clinical population were based on self-reported surveys, without any attempt to validate the clinical interview. The present study aimed to test whether the Attenuated Psychosis Syndrome (APS) could be detected in a college population by checking self-report results against an additional interview. A two-stage screening process was used in a sample of 579 college students (16-22 years old): a 16-item Chinese version of the Prodromal Questionnaire (CPQ-16) followed by the Structured Interview for Psychosis-Risk Syndromes (SIPS). Psychopathology symptoms were assessed using the Symptom Checklist-90 (SCL-90). There were 20 (3.5%) students who met the criteria for the APS according to SIPS. Compared with control students, the students with APS were more likely to be from divorced families and had more psychopathology based on the SCL-90. Certain factors on the SCL-90, including Obsessive-Compulsive (OBS), Interpersonal Sensitivity (INT), and Depression (DEP) were significantly correlated with positive psychosis risk symptoms on the SIPS, but only DEP had a strong correlation with the total score on the SIPS. These results demonstrate that the APS can be detected in a college sample and that psychosis risk symptoms are associated with co-occurring psychopathology.
BackgroundAlthough many studies have examined executive functions and facial emotion recognition in people with schizophrenia, few of them focused on the correlation between them. Furthermore, their relationship in the siblings of patients also remains unclear. The aim of the present study is to examine the correlation between executive functions and facial emotion recognition in patients with first-episode schizophrenia and their siblings.MethodsThirty patients with first-episode schizophrenia, their twenty-six siblings, and thirty healthy controls were enrolled. They completed facial emotion recognition tasks using the Ekman Standard Faces Database, and executive functioning was measured by Wisconsin Card Sorting Test (WCST). Hierarchical regression analysis was applied to assess the correlation between executive functions and facial emotion recognition.ResultsOur study found that in siblings, the accuracy in recognizing low degree ‘disgust’ emotion was negatively correlated with the total correct rate in WCST (r = −0.614, p = 0.023), but was positively correlated with the total error in WCST (r = 0.623, p = 0.020); the accuracy in recognizing ‘neutral’ emotion was positively correlated with the total error rate in WCST (r = 0.683, p = 0.014) while negatively correlated with the total correct rate in WCST (r = −0.677, p = 0.017). People with schizophrenia showed an impairment in facial emotion recognition when identifying moderate ‘happy’ facial emotion, the accuracy of which was significantly correlated with the number of completed categories of WCST (R2 = 0.432, P < .05). There were no correlations between executive functions and facial emotion recognition in the healthy control group.ConclusionsOur study demonstrated that facial emotion recognition impairment correlated with executive function impairment in people with schizophrenia and their unaffected siblings but not in healthy controls.
Aim:The aim of this study was to examine the reliability, validity, sensitivity and specificity of the Chinese version of the 16-item Prodromal Questionnaire (CPQ-16) for identifying attenuated psychosis syndrome (APS) in a college population. Methods:The participants were recruited from a university. Five hundred seventy-nine students completed the CPQ-16 and the Symptom Checklist-90. One class (n = 79) was randomly selected to be retested with the CPQ-16 after 2 weeks. A randomly selected group of 49 individuals who tested positive and 50 individuals who tested negative were interviewed using the Structured Interview for Prodromal Syndromes (SIPS). Results:The internal consistency reliability was good (Cronbach's α = 0.72). The test-retest reliability was 0.88. The total score on the CPQ-16 was moderately to highly correlated with the total score on the Symptom Checklist-90 and all of the subscales (r = 0.39-0.67, P < 0.001). A cut-off CPQ-16 score of 9 was used to differentiate between those with a APS diagnosis on the SIPS versus those with no SIPS diagnoses; this cut-off value yielded 85% sensitivity, 87% specificity, a positive predictive value of 63% and a positive likelihood ratio of 6.69. The area under the ROC curve (AUC) was significant for the CPQ-16 total score (AUC = 0.93, SE = 0.026, 95% CI = 0.87-0.98, P < 0.001). Based on the proposed cut-off score, the CPQ-16 yielded a positive rate of 5.0% (29/579). Conclusions:The CPQ-16, administered in a face-to-face interview, demonstrated high reliability and the ability to identify college students at risk for psychosis.
BackgroundThis study aimed to explore the characteristics of event-related potentials induced by facial emotion recognition in patients with first-episode schizophrenia and in their siblings.MethodsIn this case-control study, 30 first-episode schizophrenia patients, 26 siblings, and 30 healthy controls were enrolled. They completed facial emotion recognition tasks from the Ekman Standard Faces Database as an induction for evoked potentials. Evoked potential data were obtained using a 64-channel electroencephalography system. Average evoked potential waveforms were computed from epochs for each stimulus type. The amplitudes and latency of the event-related potentials for P100 (positive potential 100 ms after stimulus onset), N170 (negative potential 170 ms after stimulus onset), and N250 (fronto-central peak) were investigated at O1, O2, P7, and P8 electrode locations.ResultsThere were significant differences between the groups for P100 amplitude (F = 11.526, P < 0.001), electrode position (F = 450.592, P < 0.001), emotion (disgust vs. happiness vs. fear) (F = 1722.467, P < 0.001), and emotion intensity (low vs. moderate vs. high) (F = 1737.169, P < 0.001). Post hoc analysis showed significantly larger amplitudes in the schizophrenia group at the O1, O2, P7, and P8 electrode positions. There were no significant differences between the siblings of schizophrenia patients and the healthy controls.ConclusionsPatients with schizophrenia showed abnormalities in P100 amplitude, but similar results were not observed in their siblings. These results provide evidence of dysfunctional event-related potential patterns underlying facial emotion processing in patients with schizophrenia. P100 may be a characteristic index of schizophrenia.Electronic supplementary materialThe online version of this article (doi:10.1186/s12888-016-1189-7) contains supplementary material, which is available to authorized users.
In Chinese FES patients, the longitudinal course of cognitive function tends to worsen in verbal learning and memory, executive function and motor speed, while that of social function tends to improve. DUP was not found to be associated with cognitive or social deterioration in Chinese FES.
This cross-sectional survey aimed to explore quality of life (QoL) and its correlated factors in Chinese patients with persistent somatoform pain disorder (PSPD) and their related correlation factors in Shanghai, China. A total of 60 patients were assessed with Short Form (36) health survey (SF-36) for QoL, medical outcomes study pain measurement (MOSPM) for pain symptoms, Hamilton depression scale - 17 items (HAMD) for depression and Hamilton anxiety scale (HAMA) for anxiety. Results were as follows: (1) Patients scored significantly lower on all SF-36 subscales' scores ( p < .01) apart from the mental health and vitality subscales; (2) With the exception of the general health subscale, SF-36 subscales' scores were negatively correlated with the total score of MOSPM, three factor scores of MOSPM, and total scores of HAMD and HAMA; (3) PSPD patients with severe depression had significantly lower scores (p < .01) on SF-36 subscales' scores (except for GH subscale) and component summary scores as compared to PSPD patients with none or moderate depression; and (4) Multiple linear stepwise regression revealed that SF-36's physical component summary (PCS) subscale correlated with patients' age and MOSPM total score while SF-36's mental component summary (MCS) subscale correlated with total scores of HAMD and MOSPM total score. In sum, PSPD patients had a lower QoL as compared to general population. Pain, depression, and anxiety were significantly correlated with QoL of PSPD patients while age, pain, and depression were important factors influencing PCS and MCS.
IntroductionA significant number of mania patients fail to respond to current pharmacotherapy, thereby there is need for novel augmentation strategies. The results of some early studies showed the effectiveness of cholinomimetics in the treatment of mania. One open case series suggested the efficacy of donepezil in the treatment of bipolar disorder. Our aim was to explore whether an oral cholinesterase inhibitor, donepezil, administered during a 4-week treatment period, would benefit patients with acute mania.MethodsWe conducted a 4-week double-blind, placebo-controlled trial of donepezil as an adjunctive treatment to lithium in patients with acute mania. Eligible subjects were randomly assigned to receive donepezil or placebo in addition to lithium. Donepezil was started at 5 mg/day, and increased to 10 mg/day in the first week. Patients were rated with the Young Mania Rating Scale (YMRS) and Brief Psychiatric Rating Scale (BPRS) at baseline, day 1, week 1, week 2, and week 4.ResultsOut of the 30 patients who were enrolled, 15 were on donepezil and 15 were on placebo. All patients completed the 4-week trial. On the first day, there was a difference of 1.97 units on the psychomotor symptoms scale of the YMRS in the donepezil group as compared to the placebo group (t = 2.39, P = 0.02). There was a difference of 0.57 units (t = 2.09, P = 0.04) in the speech item and a difference of 0.29 units in the sexual interest item (t = 2.11, P = 0.04) in the donepezil group as compared to the placebo group. The total YMRS difference on the first day approached the conventional significance level (1.97 units, t = 1.84, P = 0.07). Over the course of 4 weeks, we failed to find that donepezil produced any significant difference in the YMRS (6.71 units difference, t = −1.44, P = 0.16) or the BPRS scale (1.29 units difference, t = −0.33, P = 0.75) as compared to placebo. Ten subjects (66.67%) in both groups met the criteria for clinical response (Fisher’s exact P = 1.00). Five subjects (33.33%) in the donepezil group met the criteria for clinical remission while nine subjects (60.00%) in the placebo group met the remission criteria (Fisher’s exact P = 0.27).ConclusionUse of the oral anticholinergic donepezil had some benefit in the augmentation of lithium treatment on the first day, but did not provide any significant benefits in the long-term.
Depression and diabetes mellitus (DM) have existed since ages. Yet, the etiologies of both diseases are unclear till date. However, the effects resulting from these diseases are well documented. Comorbidity of both disorders leads to increase disability and mortality rates. Besides presenting the epidemiological status of depression in DM, this review aims to highlight the different hypotheses governing the association of depression in DM and summarize the current trend in detection and management of depression. A high index of suspicion is required to detect depression in diabetic patients. There seems to be higher prevalence of depression in type 2 diabetes than in type 1 diabetes. Treatment should be tailored as per the individual needs and presence of comorbidity. Though there is no gold standard treatment for depressive diabetics, combinations of both pharmacological and non-pharmacological interventions are likely to improve outcomes. Selective serotonin reuptake inhibitors (SSRIs) and selective norepinephrine reuptake inhibitors (SNRIs) are preferred to conventional antidepressants. Collaborative care, psychoeducation and behavioral interventions are helpful in motivating patients to maintain treatment and improve psychological well-being and quality of life. Untreated depression in diabetics is costly to the health care and economic system as there is an increase in functional impairment and mortality rate. More efforts need to be made to effectively screen, diagnose and treat patients with comorbidity of diabetes and depression.
