    INTRODUCTION: The Schizotypal Personality Questionnaire (SPQ) is a widely used self-report measurement instrument for the assessment of schizotypal personality traits. However, the factor structure of the SPQ has been a matter of some debate. As a contribution to this debate, we examined the factor structure of the SPQ in Malaysian adults.

    METHOD: A total of 382 Malaysian adults completed a Malay translation of the SPQ. Confirmatory factory analysis was used to examine the fit of 3- and 4-factor solutions for the higher-order dimensionality of the SPQ. Ethnic invariance for the best-fitting model was tested at the configural, metric, and scalar levels, and a multivariate analysis of variance was used to examine sex and ethnicity differences in domain scores.

    RESULTS: The 4-factor model provided a better fit to the data than did the 3-factor model. The 4-factor model also demonstrated partial measurement invariance across ethnic groups. Latent mean comparisons for sex and ethnicity revealed a number of significant differences for both factors, but effect sizes were small.

    DISCUSSION: The 4-factor structure of the SPQ received confirmatory support and can be used in Malay-speaking populations.

    INTRODUCTION: The objective of this study was to establish the psychometric properties of the AD8 Dementia Screening Interview in patients with Parkinson disease (PD) with or without cognitive impairment using the Montreal Cognitive Assessment Tool (MoCA) for comparison.

    METHODS: The AD8 was translated into Malay for Malay-speaking participants. A correlation analysis and a receiver operator characteristic curve were generated to establish the psychometric properties of the AD8 in relation to the MoCA.

    RESULTS: One hundred fifty patients and their caretakers completed the AD8 and MoCA. Using a cutoff score of 1/8, the AD8 had 81% sensitivity and 59% specificity for the detection of cognitive impairment in PD. With a cutoff score of 2/8, the AD8 had 83% specificity and 64% sensitivity. The area under the receiver operator characteristic curve was 80%, indicating good-to-excellent discriminative ability.

    DISCUSSION: These findings suggest that the AD8 can reliably differentiate between cognitively impaired and cognitively normal patients with PD and is a useful caregiver screening tool for PD.

    INTRODUCTION: Health issues often differ from one population to another. Assessing different aspects of the health condition is a vital step toward developing and designing appropriate prevention and treatment programs to reduce health problems in any group or population. This study aimed to assess both the prevalence of stress and the coping mechanisms as well as identify the predictors of stress levels among adolescents in Malaysian orphanages.

    METHODS: Overall, 307 male and female adolescents (aged 13-18 y old) living in 9 private orphanages located in Klang Valley, Malaysia, participated in this cross-sectional study. Brief COPE scale and Depression, Anxiety and Stress Scale-21 were used as the main instruments in the current study.

    RESULTS: The results of the current study showed female adolescents and participants with a higher level of education were more likely to experience stress. The results also showed significant differences between boys and girls in using of coping mechanisms in self-distraction (t = -2.39, P = .01), substance use (t = 2.12, P = .03), use of emotional support (t = -2.70, P = .001), humor (t = 2.28, P = .02), and religion (t = -2.19, P = .02). Denial, venting, religion, humor, planning, and active coping were identified as predictors of stress among participants.

    DISCUSSION: The results showed a high prevalence of stress and a negative coping pattern among participants. The finding of the current study also showed the urgency of taking immediate action to reduce stress and improve coping methods among Malaysian institutional adolescents.

    INTRODUCTION: The occurrence of female sexual dysfunction (FSD) in patients with major depressive disorder (MDD) receiving selective serotonin reuptake inhibitors (SSRIs) treatment gives negative impacts on patients' quality of life and causes treatment discontinuation. We aimed to investigate whether genetic polymorphism of identified candidate gene is associated with FSD in our study population.

    METHODS: This is a cross-sectional study. A total of 95 female patients with MDD who met the criteria of the study were recruited and were specifically assessed on the sexual function by trained psychiatrists. Patients' DNA was genotyped for BDNF Val66Met polymorphism using real-time polymerase chain reaction.

    RESULTS: The prevalence of FSD in this study is 31.6%. In the FSD group, patients with problematic marriage were significantly more frequent compared with patients who did not have problematic marriage (P = 0.009). Significant association was detected in the lubrication domain with BDNF Val66Met polymorphism (P = 0.030) using additive genetic model, with even stronger association when using the recessive model (P = 0.013).

    DISCUSSION: This study suggested that there was no significant association between BDNF Val66Met with FSD. However, this polymorphism is significantly associated with lubrication disorder in patients treated with SSRIs.

    INTRODUCTION: To evaluate efficacy and safety of lurasidone for the treatment of Asian patients with schizophrenia.

    METHODS: Patients with schizophrenia from Japan, South Korea, Malaysia, and Taiwan were randomly assigned to 6 weeks of double-blind treatment with 40 or 80 mg/d of lurasidone or placebo. The primary efficacy measure was change from baseline to week 6 on the Positive and Negative Syndrome Scale (PANSS) total score. Efficacy was evaluated using a mixed-model repeated-measures (MMRM) analysis in the modified intention-to-treat (mITT) population.

    RESULTS: On the basis of the analysis for the mITT population, the estimated difference score for lurasidone 40 and 80 mg/d vs placebo was -4.8 (P = 0.050) and -4.2 (P = 0.080). For the full intention-to-treat (ITT) population, the difference score for lurasidone 40 and 80 mg/d vs placebo was -5.8 (P = 0.017) and -4.2 (P = 0.043). The most frequent adverse events in the lurasidone 40 and 80 mg/d and placebo groups, respectively, were akathisia (7.3%, 10.4%, 3.3%), somnolence (6.0%, 2.6%, 0.7%), and vomiting (6.0%, 5.8%, 2.0%). The proportion of patients experiencing clinically significant weight gain (≥7%) was 5.3% for lurasidone 40 mg/d, 1.3% for 80 mg/d, and 1.4% for placebo. End point changes in metabolic parameters and prolactin were comparable for both lurasidone groups and placebo.

    CONCLUSIONS: In the ITT (but not the mITT) population, treatment with lurasidone was associated with significant improvement in the PANSS total score in patients with schizophrenia. Lurasidone was generally well tolerated with minimal impact on weight and metabolic parameters.

    INTRODUCTION: Cognitive dysfunction has been significantly associated with functional impairment in patients with major depressive disorder (MDD).

    METHODS: This is a subgroup analysis of 211 Malaysian patients recruited from the multicountry, multicenter, cross-sectional Cognitive Dysfunction in Asian patients with Depression (CogDAD) study. Depression severity, cognitive dysfunction, and functional disability were assessed and compared with the overall CogDAD study population. Factors associated with functional disability were also evaluated in this Malaysian patient population.

    RESULTS: Approximately half of the Malaysian patients were in their first depressive episode, with the majority being treated for mild-to-moderate depression. Furthermore, Malaysian patients experienced cognitive dysfunction, with self-reported Perceived Deficits Questionnaire (PDQ-D) scores falling within the third quartile of PDQ-D severity. Malaysian patients also reported functional disability evidenced by a mean total Sheehan Disability Scale (SDS) score of 11.47 ± 6.68, with the highest SDS score reported in the "Social Life/Leisure Activities" domain. Compared with the overall CogDAD study population, the Malaysian patient population had comparable patient demographics in terms of marital and working status; outcome scores for PHQ-9 (9-item Patient Health Questionnaire for self-reported depression severity), PDQ-D and SDS; and worst perceived cognitive dysfunction reported in the "Attention/Concentration" domain. Factors found to be significantly associated with functional disability were PDQ-D score, sick leave taken, and antidepressant treatment (P

    Providing optimal care to patients with recent-onset psychosis can improve outcomes and reduce relapse. However, there is a lack of consistency of the implementation of guidelines for such patients across the Asia-Pacific region. We determined a pragmatic set of recommendations for use on a day-to-day basis to help provide optimal care at this crucial stage of illness. The recommendations were developed over a series of meetings by an international faculty of 15 experts from the Asia-Pacific region, Europe, and South Africa. A structured search of the PubMed database was conducted. This was further developed based on the faculty's clinical experience and knowledge of the literature into 10 key aspects of optimal care for patients during the first five years of a diagnosis of a psychotic disorder, with particular relevance to the Asia-Pacific region. Several common principles emerged: adherence to antipsychotic medications is crucial; substance abuse, psychiatric and medical comorbidities should be addressed; psychosocial interventions play a pivotal role; and family members can play a vital role in overall patient care. By following these recommendations, clinicians may improve outcomes for patients with recent-onset psychosis.
