“…All participants completed the self-rated Centre for Epidemiologic Studies Depression Scale (CES-D) and the Sinhala version of the Pittsburgh Sleep Quality Index (PSQI). Both these scales have been validated for Sri Lanka [12,13]. If the patients had difficulty understanding the questionnaires due to low literacy level or any other reason the questions were clarified by the first author.…”

Introduction Lifetime prevalence of depression varies across countries and different populations. Depression is a common comorbidity of physical illness. Patients with depression are known to present with somatic symptoms. Depression is under-diagnosed in primary care settings.Objectives To estimate the prevalence of depression in patients attending the outpatient department (OPD) of a tertiary care hospital in the Western Province of Sri Lanka.Methods A cross-sectional descriptive study was conducted in the OPD of the National Hospital of Sri Lanka (NHSL). Sample size was 205. Every fifth patient aged between 18 and 60 years who attended the OPD was recruited until the required number was met. Centre for Epidemiologic Studies Depression Scale (CES-D) was used to identify depression.Results There were 114 (55.6%) females. Mean age was 50 years (SD 13.68 Conclusions Prevalence of depression in outpatients is similar to that reported in other parts of the world. None of the patients with depression presented seeking help for depressive symptoms.

“…A systematic review including 37 studies confirmed that the PSQI had a fair or good Cronbach’s alpha coefficient (ranging from 0.64 to 0.83) ( 17 , 22 ). Previous studies about community-dwelling older adults demonstrated single-factor ( 23 ), two-factor ( 24 ) and three-factor models ( 25 ) with different methodologies. Published findings also showed adequate internal consistency ( 19 ) and construct validity but varying factor structures among the English, Chinese, Korean, Portuguese, Nigerian and Greek versions of the PSQI ( 26 – 30 ).…”

Background: The Pittsburgh Sleep Quality Index (PSQI) is a widely used self-report questionnaire that measures general sleep quality in general populations. However, its psychometric properties have yet to be thoroughly examined in longevous persons. Objectives: This study aimed to explore the reliability, validity and factor structure of the Chinese-language version of the PSQI in community-dwelling centenarians. Methods: A total of 958 centenarians (mean age = 102.8 years; 81.8% females) recruited from 18 regions in Hainan, China, completed the PSQI scale. Cronbach's alpha coefficient was used to measure the internal consistency. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to explore the validity and factor structure of the PSQI in this sample. Correlations between the global PSQI score and physical function, depression symptoms, self-reported health status and subjective wellbeing were used to assess divergent validity. Results: The Cronbach's a coefficient of the PSQI was 0.68, and it increased to 0.78 after two components (medication use and daytime dysfunction) were removed. The Spearman correlation coefficients of the PSQI score with each component were statistically significant (P<0.01). EFA yielded a two-factor structure model of the original PSQI-7 and a one-factor structure model of the simplified PSQI-5. The one-factor model with five components (c 2 /df =1.59, CFI=0.99, RMSEA=0.03) fit the data well and had good configural invariance across demographic characteristics (0.53< D c 2 <5.58, P>0.05). Conclusions: The original PSQI showed acceptable applicability in Chinese communitydwelling centenarians, and its psychometric characteristics moderately improved after

The assessment of fatigue, sleep quality and functional disability requires the use of validated instruments such as the Fatigue Severity Scale (FSS), the Pittsburgh Sleep Quality Index (PSQI) and the Modified Health Assessment Questionnaire (mHAQ) respectively. The aim of this study was to translate and validate these instruments into the Maltese Language. METHOD: Forward translation from the original English version into Maltese was carried out by two translators. The two versions were compiled to produce a preliminary initial Maltese translation. This was translated back into English by two other translators. This led to the development of the pre-final version of the Maltese translation, which was pilot-tested in 20 bilingual patients with systemic lupus erythematosus. RESULTS: Psychometric testing revealed good reliability of the Maltese translation of the three questionnaires. Cronbach's alpha of the Maltese versions of the FSS, PSQI and mHAQ were 0.877, 0.859 and 0.897 respectively, showing good internal consistency. Validity of the Maltese version of the FSS was shown, since it had a significant positive correlation with visual analogue scale for fatigue (r=0.809, p<0.001). CONCLUSION: The Maltese translations were thus finalised, and could be used for clinical assessment or research purposes.
