Depression literacy among Chinese stroke survivors.

OBJECTIVES: Mental health literacy is fundamental to the pursuit of health. Little is known about patients' literacy levels regarding depression even though it is common among elderly stroke survivors. This paper will report the level of mental health literacy and thematic constructs of depression interpreted by a group of stroke survivors. METHOD: Qualitative data on patients' understanding of 'depression' in Chinese were translated and analyzed by an academic and a researcher separately to identify emerging constructs using a thematic approach. Out of 214 ischemic stroke older adults, aged 50+, 85 were able to explain the term in their own words after their first stroke attack. RESULTS: The majority of stroke patients (60%, 129 out of 214) had never heard of depression and only four referred to it as a medical disease. Only a third would like to learn more about depression. Older Chinese adults depicted depression mainly by using words in the cognitive and affective domains, but the descriptors used were mostly non-specific and might not match the diagnostic criteria for depression or the commonly used screening tools. CONCLUSION: Low mental health literacy among older patients indicated that much more work needs to be done in health promotion and education on depression literacy.

The smiley as a simple screening tool for depression after stroke: a preliminary study.

UNLABELLED: In Hong Kong, there is a paucity of evidence to support which tool is superior in measuring depression after stroke (DAS). A simple, non-language-based, culturally neutral, non-verbal and easy to apply tool that is not highly dependent on training will be desirable. OBJECTIVES: The present study aimed to examine the clinical utility of three smiley pictures in detecting DAS for older Chinese patients at 1 month after first-ever ischemic stroke. METHODS: This was a cross-sectional study. A total of 253 stroke patients were interviewed by a research nurse at 1-month follow-up. RESULTS: Taking Diagnostic and Statistic Manual (DSM IV) as the gold standard, the measurement properties of emoticon (sad) in terms of sensitivity, specificity, positive and negative predictive values, as well as Kappa's value were found comparable to Geriatric Depression Scale (GDS). The emoticon (happy) demonstrated a highly significant inverse relationship with all depression assessment tools (p<0.001). It was also found that the emoticon (flat) could capture 98% of all depressed subjects identified by DSM IV, although its predictive values were less satisfactory. CONCLUSIONS: The smiley pictures seemed to fulfil the requirements for early and prompt screening among older patients. Cultural implication regarding emotions dissipation among Chinese patients should be further studied.

The reliability and validity of the Alzheimer's Disease Assessment Scale Cognitive Subscale (ADAS-Cog) among the elderly Chinese in Hong Kong.

INTRODUCTION: The Alzheimer's Disease Assessment Scale cognitive subscale (ADAS-cog) was reported to be a sensitive cognitive function assessment scale for Alzheimer's Disease (AD). The English, Greek, Spanish but not Chinese versions had been validated previously. OBJECTIVES: The objectives of the present study were to investigate the reliability and validity of an adapted Chinese version of the ADAS-cog among Chinese elderly AD patients in Hong Kong. MATERIALS AND METHOD: Thirty-nine subjects were recruited during the period July to December 1998. Twenty were AD patients while 19 were non-demented normal subjects. Two raters administered the ADAS-cog scale thrice on different occasions. RESULTS: The internal consistency (Cronbach's alpha) of the ADAS-cog were 0.91, 0.88 and 0.65 for the whole group, the AD and normal (i.e. non-demented) subjects respectively. The test-retest reliability as measured by the Spearman's rho correlation coefficients were 0.96, 0.86 and 0.86 for the whole group, AD and normal subjects, respectively, (all P < 0.001). The Spearman's rho correlation coefficients for inter-rater reliability were 0.95 (P < 0.001), 0.91 (P < 0.001) and 0.65 (P = 0.003) for the whole group, AD and normal subjects, respectively. The ADAS-cog score was inversely related to the Mini-Mental Status Examination (MMSE) score (Spearman's rho = -0.91; P < 0.001). The ADAS-cog score was directly proportional to the Clinical Dementia Rating (CDR) (rho = 0.89; P < 0.001). Forward stepwise discriminant function analysis between AD and normal subjects yielded a canonical discriminant function with 3-question items (i.e. word recall test, orientation and comprehension of speech; P < 0.001). This short version had a sensitivity of 90%, specificity of 94.7% and overall accuracy of 92.3%. CONCLUSION: The Chinese version of ADAS-cog subscale is both reliable and valid among the elderly Chinese in Hong Kong.

A study of elderly suicides in Hong Kong.

Hong Kong has one of the highest rates of suicide among the elderly in the world. Most of the existing suicide prevention programs have had very little effect on the elderly, who rarely utilize these programs. This study aims to help in understanding the problem, so that effective prevention can be provided to this high-risk group of suicidal people. Specifically, the study (1) describes the characteristics of the suicidal elderly, (2) investigates the reason(s) why the elderly are in distress and become suicidal, and (3) formulates a policy and service model to reach the elderly high-risk group. This research project involves secondary data analysis. Police records on elderly suicide cases in 1992 were scrutinized to find out the major reason(s) for fatal death in the elderly. Our study points out those districts that are more crowded and have fewer medical and social facilities tended to have higher suicide rates. Most of the deaths occurred at home or nearby, and the suicidal elderly were alone before their death. The majority of elderly suicide victims suffered from chronic diseases. Very few of them, however, were totally dependent: About 40% of the cases had consulted medical practitioners, and 27% had consulted psychiatrists within one month before their deaths. Close to 70% of the cases had indicated to family members or other their suicidal thoughts, and many of them had revealed numerous suicidal indications. Both policy and practice issues are discussed in light of the findings.

Comparison of type A enterotoxigenic Staphylococcus aureus strains isolated from geographically far distant locations by pulsed field gel electrophoresis.

Staphylococcal enterotoxin A (SEA) is one of the major staphylococcal enterotoxins which may cause food-borne outbreaks. In order to investigate the difference in genomic types and to elucidate the most disseminated strains for enterotoxin A-producing strains of Staphylococcus aureus, a total of 60 SEA Staph. aureus strains isolated from food and clinical samples in Taiwan and 30 strains of the same enterotoxigenic type of strains obtained from geographically far distant locations were compared for their pulsed field gel electrophoresis (PFGE) patterns. The rare cutting endonuclease SmaI generated 10 distinct genome patterns for the 60 local SEA isolates and 15 and eight genome patterns, respectively, for the 20 and 10 SEA strains originally isolated from the USA and other countries. The local isolates are less diverse in genome patterns as compared to the US isolates. Of all these PFGE patterns, a certain pattern, such as pattern 3, is shared by the food and clinical isolates and the local and foreign isolates. Thus, although SEA Staph. aureus strains from geographically far distant locations showed considerable genetic diversity, PFGE pattern 3 strain might be one of the most disseminated strains.

Vietnamese refugee children in camps in Hong Kong.

Vietnamese refugee children staying in an open camp in Hong Kong were interviewed to find out the nature of their war experience. The effects of war and refugee experience on their fears about being hurt or killed were assessed. Most of the Vietnamese children in the present sample travelled to Hong Kong with their family and had little experience of separation, death or injury of close family members. However, about two-thirds of them had witnessed violence and one-third reported experience of being assaulted. Children exposed to unpleasant war experience were more likely to report a fear of being hurt than those not exposed to similar negative events. However, there was no consistent finding relating other types of fear to war experience. The family and the cohesiveness of the community in which they lived may have protected them against adverse psychological reactions.
