METHODS: A total of 171 patients who received treatment in a local heart centre were included in this study. Several questionnaires such as the Life Event Checklist-5, Posttraumatic Stress Disorder Checklist for DSM-5 and Patient Health Questionnaire-9 were used to measure their traumatic experiences and PTSD and depressive symptoms, respectively. Physiological measures were also examined. Data were analysed using SPSS.
RESULTS: The chi-square test showed significant differences in the percentage of reported PTSD symptoms among the patients with CVD (24.0%), patients with kidney disease (4.3%) and patients with other health problems (7.1%). The patients with CVD reported having a significantly higher percentage of PTSD and depressive symptoms than the patients with other medical conditions. The patients with CVD who reported having PTSD symptoms had significant systolic blood pressure (SBP) and heart rate changes compared to the patients who did not. The patients who reported PTSD symptoms had a significantly shorter sleep duration than their counterparts. The SBP and diastolic blood pressure differed significantly between the patients with and without PTSD symptoms.
CONCLUSION: Earlier detection, prevention and intervention related to trauma exposure and PTSD symptoms are suggested to reduce the CVD risk.
METHOD: Confirmatory factor analysis was conducted on the DSM-5 model of PTSD, followed by a multiple indicators multiple causes (MIMIC) model to examine possible DIF using the PTSD Checklist for DSM-5. Data were analyzed from a Malaysian adolescent sample (n = 481) of which 61.7% were female, with a mean age of 17.03 years.
RESULTS: The results indicated the presence of DIF for 2 of 20 PTSD criteria. Females scored significantly higher on emotional cue reactivity (B4), and males reported significantly higher rates of reckless or self-destructive behavior (E2) while statistically controlling for the latent variables in the model. However, the magnitude of these item-level differences was small.
CONCLUSION: These findings indicate that despite the presence of DIF for 2 DSM-5 symptoms, this does not provide firm support for nonequivalence across sex. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
Methods: This study took place at the National Heart Institute and Universiti Kebangsaan Malaysia Medical Centre, Kuala Lumpur, Malaysia, between March 2013 and March 2014. A self-administered 75-item HFQOL questionnaire was designed and administrated to 164 multi-ethnic Malaysian HF patients. Exploratory factor analysis was performed to assess the instrument's construct validity. Cronbach's alpha coefficients were used to determine internal consistency.
Results: A total of 33 out of 75 items were retained in the final tool. The HFQOL questionnaire had three common factors-psychological, physical-social and spiritual wellbeing-resulting in a cumulative percentage of total variance of 44.3%. The factor loading ranges were 0.450-0.718 for psychological wellbeing (12 items), 0.394-0.740 for physical-social wellbeing (14 items) and 0.449-0.727 for spiritual wellbeing (seven items). The overall Cronbach's alpha coefficient of the questionnaire was 0.82, with coefficients of 0.86, 0.88 and 0.79 for the psychological, physical-social and spiritual wellbeing subdomains, respectively.
Conclusion: The HFQOL questionnaire was found to be a valid and reliable measure of QOL among Malaysian HF patients from various ethnic groups. Such tools may facilitate cardiac care management planning among multi-ethnic patients with HF.
