ABSTRACT
Background: The Snaith-Hamilton Pleasure Scale (SHAPS) is a self-assessment scale designed to evaluate anhedonia in various psychiatric disorders. In order to facilitate its use in Malaysian settings, our current study aimed to examine the validity of a Malay-translated version of the SHAPS (SHAPS-M). Methods: In this cross-sectional study, a total of 44 depressed patients and 82 healthy subjects were recruited from a university out-patient clinic. All participants were given both the Malay and English versions of the SHAPS, Fawcett-Clark Pleasure Scale (FCPS), General Health Questionnaire 12 (GHQ-12), and the Beck Depression Inventory (BDI) to assess their hedonic state, general mental health condition and levels of depression. Results: The results showed that the SHAPS-M has impressive internal consistency (α = 0.96), concurrent validity and good parallel-form reliability (intraclass coefficient, ICC = 0.65). Conclusion: In addition to demonstrating good psychometric properties, the SHAPS-M is easy to administer. Therefore, it is a valid, reliable, and suitable questionnaire for assessing anhedonia among depressed patients in Malaysia.
ABSTRACT
The Snaith-Hamilton Pleasure Scale (SHAPS) is a self-assessment scale designed to evaluate anhedonia in various psychiatric disorders. To facilitate its use in Malaysian settings, our current study aimed to examine the validity of the Simplified-Chinese translated version of the SHAPS (SHAPS-SC) in a group of subjects at a university out-patient clinic. Method: A total of 40 depressed patients were recruited in this cross sectional study. They were given both the Simplified Chinese and Malay versions of SHAPS, General Health Questionnaire 12 (GHQ-12) and Beck Depression Inventory (BDI) to assess their hedonic state, general mental health condition and level of depression. Results: Our study showed that SHAPS-SC had impressive internal consistency (Cronbach’s alpha 0.84) and concurrent validity, and fair parallel-forms reliability (Pearson’s correlation 0.39). Conclusion: SHAPS-SC demonstrate good psychometric properties in the evaluation of hedonic state among a group of Chinese speaking depressed patients in an out-patient setting. It is easy to administer and suitable as a valid and reliable questionnaire in assessing anhedonia among depressed patients in Malaysia.

Background and objectives: Radiation treatment in nasopharyngeal carcinoma (NPC) is known to be associated with increased prevalence of carotid stenosis. The objectives of the study was to determine the prevalence of radiation-induced extracranial carotid stenosis, plaque, carotid intima thickness (CIMT) in NPC patients; to explore whether the stenosis is due to direct effect of radiation rather than general tendency to atherosclerosis. Methods: This was a cross-sectional study conducted in the University Malaya Medical Centre from July 2011 to February 2012. The study subjects consisted of 47 NPC patients who were treated with radiation, and 47 healthy control. The patients and control had carotid duplex ultrasound and transcranial Doppler (TCD). Results: The mean age of the patients was 55.1 years, the time lapse from radiation was 76.7 ± 95.3 months. Internal carotid artery (ICA) and common carotid artery (CCA) stenosis of ≥50% was seen in 17.0% of patients vs 2.1 % of controls (p = 0.031), with 61.7% of patients and 19.1% of controls having plaque in ICA and CCA (p=0.004). CIMT was increased in 70.2% of patients and 44.7% of controls (p =0.022). Both the patient group and control had similar rate of intracranial stenosis of 12.8% in TCD. Conclusion: Extracranial internal carotid artery is the most common site of stenosis following radiotherapy in NPC. This suggests that local trauma from irradiation is the most important factor in predisposition to atherosclerosis following radiation therapy.
