PTSD's latent structure in Malaysian tsunami victims: assessing the newly proposed Dysphoric Arousal model

Armour C, Raudzah Ghazali S, Elklit A

Psychiatry Res, 2013 Mar 30;206(1):26-32.

The underlying latent structure of Posttraumatic Stress Disorder (PTSD) is widely researched. However, despite a plethora of factor analytic studies, no single model has consistently been shown as superior to alternative models. The two most often supported models are the Emotional Numbing and the Dysphoria models. However, a recently proposed five-factor Dysphoric Arousal model has been gathering support over and above existing models. Data for the current study were gathered from Malaysian Tsunami survivors (N=250). Three competing models (Emotional Numbing/Dysphoria/Dysphoric Arousal) were specified and estimated using Confirmatory Factor Analysis (CFA). The Dysphoria model provided superior fit to the data compared to the Emotional Numbing model. However, using chi-square difference tests, the Dysphoric Arousal model showed a superior fit compared to both the Emotional Numbing and Dysphoria models. In conclusion, the current results suggest that the Dysphoric Arousal model better represents PTSD's latent structure and that items measuring sleeping difficulties, irritability/anger and concentration difficulties form a separate, unique PTSD factor. These results are discussed in relation to the role of Hyperarousal in PTSD's on-going symptom maintenance and in relation to the DSM-5.

Determination of naltrexone dosage for narcotic agonist blockade in detoxified Asian addicts

Navaratnam V, Jamaludin A, Raman N, Mohamed M, Mansor SM

Drug Alcohol Depend, 1994 Feb;34(3):231-6.
PMID: 8033761

Thirty-eight, adult, male, detoxified, Malaysian opiate addicts participated in this double-blind clinical evaluation of naltrexone. Addicts from three ethnic groups: Chinese, Malays, and Indians received a weekly regimen of naltrexone (100 mg on Days 1 and 3, and 150 mg on Day 5). Subjects were randomly assigned to receive intravenous challenge with either 25 mg heroin or placebo 12, 24, 48, and 72 h after the third naltrexone dose. Physiological and subjective parameters were measured at each challenge interval. Results indicated that naltrexone was effective in blocking the physiological and psychological effects of heroin for at least 48 and 72 h, respectively, in detoxified Malaysian opiate addicts. The efficacy of naltrexone did not differ among the three ethnic groups evaluated in this study.

Using mental imagery to deliver self-regulation techniques to improve sleep behaviors

Loft MH, Cameron LD

Ann Behav Med, 2013 Dec;46(3):260-72.
PMID: 23640130 DOI: 10.1007/s12160-013-9503-9

BACKGROUND: Poor sleep habits and insufficient sleep represent significant workplace health issues.
PURPOSE: Applying self-regulation theory, we conducted a randomized, controlled trial testing the efficacy of mental imagery techniques promoting arousal reduction and implementation intentions to improve sleep behavior.
METHOD: We randomly assigned 104 business employees to four imagery-based interventions: arousal reduction, implementation intentions, combined arousal reduction and implementation intentions, or control imagery. Participants practiced their techniques daily for 21 days. They completed online measures of sleep quality, behaviors, and self-efficacy at baseline and Day 21; and daily measures of sleep behaviors.
RESULTS: Participants using implementation intention imagery exhibited greater improvements in self-efficacy, sleep behaviors, sleep quality, and time to sleep relative to participants using arousal reduction and control imagery.
CONCLUSIONS: Implementation intention imagery can improve sleep behavior for daytime employees. Use of arousal reduction imagery was unsupported. Self-regulation imagery techniques show promise for improving sleep behaviors.

Fulltext The prevalence of sexual dysfunction among postpartum women on the East Coast of Malaysia

Khalid NN, Jamani NA, Abd Aziz KH, Draman N

J Taibah Univ Med Sci, 2020 Dec;15(6):515-521.
PMID: 33318744 DOI: 10.1016/j.jtumed.2020.08.008

Objective: Sexual health is a key component of the overall health and quality of life of both men and women. Sexual dysfunction is a common condition, but it lacks professional recognition. This study aims to determine the prevalence and types of sexual dysfunctions among postpartum women in primary care clinics and their associated factors in a Malaysian cohort.
Method: In this cross-sectional study, we recruited 420 women from nine primary care clinics in Kuantan, Pahang, Malaysia. All participants had given livebirths within six weeks to six months and had attended either a postnatal or a well-child clinic at a government primary care clinic. The assessment of female sexual dysfunction (FSD) was done using a validated Malay version of the female sexual function index (MVFSFI). Data were statistically analysed using appropriate methods.
Results: More than one-third (35.5%) of women had postpartum sexual dysfunction. The most common types were lubrication disorder 85.6% (n = 113), followed by loss of desire 69.7% (n = 92) and pain disorders 62.9% (n = 83). Satisfaction disorder 7.3% (n = 27), orgasmic disorder 9.7% (n = 56) and arousal disorder 11.0% (n = 41) were less common sexual problems. The independent associated factors for FSD were high education level (adjusted odd ratio = 1.717, 95% CI 1.036-2.844; p

Fulltext The prevalence and factors influencing posttraumatic stress disorders (PTSD) among helpseeking women experiencing domestic violence in Malaysia

Objective: The aim of the study is to examine the prevalence and factors influencing PTSD among a sample of help-seeking women experiencing domestic violence. Methods: This was a cross-sectional survey study of 40 women in two shelters in Malaysia from 2007 to 2008. Measures include the Detailed Assessment of Posttraumatic Stress; the Measure of Wife Abuse; the Posttraumatic Cognitions Inventory; the Coping Scale for Adults; and the Provision of Social Relations. Results: Results showed that 60% of subjects
exhibited patterns of symptoms consistent with the diagnosis of PTSD. The most prominent posttraumatic symptoms reported were re-experience, avoidance, dissociative responses, and symptoms of increased arousal. Both negative appraisals about themselves and self blame for the abusive situations were positively associated with increased tendency to develop PTSD. The greater use of optimism coping style and the higher quality social
support appeared to lead to a significantly reduced tendency of developing PTSD. Negative appraisals about themselves were found to be the strongest positive predictor of PTSD [R² = 0.32, F(1,38)=17.67, p

Fulltext Sexual desire and sexual arousal in Malaysian women: are they of the same entity?

ASEAN Journal of Psychiatry, 2009;10(1):43-53.
MyJurnal

Objective: To investigate the correlation between sexual desire and sexual arousal among Malaysian women in a primary care setting. Methods: The Malay Version of Female Sexual Function Index (MVFSI) was used to assess low sexual desire and lack of sexual arousal among the respondents. A total of 230 married women aged 18 – 70 years old participated in this study. Their sociodemographic, marital profiles and correlation between low sexual desire and lack of sexual arousal were examined. Results: More than 60% respondents with low sexual desire have co-exist low sexual arousal and 94.4% respondents with high sexual desire do have high sexual arousal ( χ²= 79.6, p

Consumer preference is rapidly changing from 2D to 3D movies due to the sensational effects of 3D scenes, like those in Avatar and The Hobbit. Two 3D viewing technologies are available: active shutter glasses and passive polarized glasses. However, there are consistent reports of discomfort while viewing in 3D mode where the discomfort may refer to dizziness, headaches, nausea or simply not being able to see in 3D continuously.
