A community-based epidemiological study of health anxiety and generalized anxiety disorder.

This community-based study examined the frequency of worry about personal health in respondents with and without generalized anxiety disorder (GAD), and the impact of health anxiety on the disorder. A random community-based telephone survey of 5118 Chinese respondents aged 18-64 was conducted. A fully structured questionnaire covered the DSM-IV-TR criteria of GAD, major depressive episode (MDE), eight domains of worry, the seven-item Whiteley Index (WI-7), health service use, and socio-demographic information. Worry about personal health ranked fifth (75.6%) among eight domains of worries examined. GAD respondents with high level of health anxiety were significantly older, less educated, and had lower family income. High health anxiety significantly increased the occurrence of one-year MDE, previous persistent worry, previous persistent low mood, number of domains of worries, number of non-core DSM-IV-TR GAD symptoms, health service use, and mistrust of doctors. Health anxiety is common in GAD and may signify greater severity of the disorder.

Gastrointestinal dysfunction in Chinese patients with fat-phobic and nonfat-phobic anorexia nervosa.

Although gastrointestinal and other somatic symptoms are common in patients with anorexia nervosa (AN), and a growing cross-national literature indicates that not all anorexic patients exhibit the core diagnostic symptom of fat phobia, the relationship between somatic symptoms and anorexic illness remains unclear. Our objective was to evaluate gastrointestinal dysfunction (GD) in Chinese patients with fat phobic (FP) and nonfat phobic (NFP) anorexia nervosa. A total of 113 FP- and 28 NFP-AN outpatients underwent standardized clinical assessment and completed a new 8-item GD scale and other psychopathological measures. A majority (79.4%) of AN patients reported at least some gastrointestinal complaints on the GD scale (Cronbach's alpha = 0.78). FP-AN patients scored significantly higher than NFP-AN patients. The FP-AN with high GD group reported a higher level of specific and general psychopathology than the FP- and NFP-AN with low GD groups. Contrary to expectations, gastrointestinal symptoms were more common in FP-AN than NFP-AN patients. FP-AN with high GD was more severe than FP- and NFP-AN with low GD. The current fat phobic conceptualization of the anorexic illness may overlook its phenomenologic heterogeneity and reify a dichotomy that is inconsistent with patients' varied experience of food restriction.

A general population study of the Chinese Whiteley-7 index in Hong Kong.

OBJECTIVE: To examine the psychometric properties of the Chinese seven-item Whiteley Index (WI-7) in the general population of Hong Kong. METHODS: A random community-based telephone survey of 3014 respondents aged 15-65 was conducted using a fully structured questionnaire that included the WI-7, 15-item Patient Health Questionnaire (PHQ-15), Sheehan Disability Scale (SDS), and items about the frequency of health service use, perceived helpfulness of doctors, level of satisfaction with doctors, and sociodemographic variables. A sub-sample of 199 respondents was re-interviewed to assess test-retest reliability. RESULTS: The WI-7 exhibited satisfactory internal consistency (Cronbach's α=0.73) and stable one-month test-retest reliability. The most commonly endorsed item was "worrying a lot about one's health" (55.7%), followed by "worrying about getting the disease oneself if it is brought to his/her attention" (48.7%) and "bothered by many different pains and aches" (33.9%). Age, gender, and monthly family income significantly predicted WI-7 score. Confirmatory factor analysis revealed that a 2-factor structure was superior to a 1-factor structure in fitting the data. WI-7 total score was positively associated with PHQ-15 somatic distress, SDS impairment, number of healthcare visits, lower levels of perceived helpfulness of doctors and of satisfaction with doctors. CONCLUSION: The Chinese WI-7 exhibits satisfactory reliability and internal validity in a general population. It is a promising tool for the empirical examination of health anxiety which is a common experience with a mostly typical epidemiological profile among Chinese people in Hong Kong.

Prevalence and correlates of social fears in Hong Kong.

This study examined the 12-month prevalence of social fears and their correlates in Hong Kong. A random telephone survey of 3006 Chinese individuals aged 15-45 years was conducted using a questionnaire that covered sociodemographic information, 14 social fears, age of onset, duration of fear, DSM-IV diagnostic features of social anxiety disorder and other psychosocial features. The prevalence of any social fear was 28.7%. The most common fear was talking to a person of higher status. Respondents with social fears were more likely to be younger and female than those without. A two-step cluster analysis revealed three subgroups with 1-3 (34.0%), 4-7 (43.9%) and 8-13 (22.0%) fears, respectively. As the number of social fears increased across these subgroups, respondents exhibited younger age of onset, more physical symptoms, avoidance behavior, impairment, and suicidality. The prevalence and profile of social fears among Chinese people resembled those of their Western counterparts.

The experience of SARS-related stigma at Amoy Gardens.

Severe Acute Respiratory Syndrome (SARS) possesses characteristics that render it particularly prone to stigmatization. SARS-related stigma, despite its salience for public health and stigma research, has had little examination. This study combines survey and case study methods to examine subjective stigma among residents of Amoy Gardens (AG), the first officially recognized site of community outbreak of SARS in Hong Kong. A total of 903 residents of AG completed a self-report questionnaire derived from two focus groups conducted toward the end of the 3-month outbreak. Case studies of two residents who lived in Block E, the heart of the SARS epidemic at AG, complement the survey data. Findings show that stigma affected most residents and took various forms of being shunned, insulted, marginalized, and rejected in the domains of work, interpersonal relationships, use of services and schooling. Stigma was also associated with psychosomatic distress. Residents' strategies for diminishing stigma varied with gender, age, education, occupation, and proximity to perceived risk factors for SARS such as residential location, previous SARS infection and the presence of ex-SARS household members. Residents attributed stigma to government mismanagement, contagiousness of the mysterious SARS virus, and alarmist media reporting. Stigma clearly decreased, but never completely disappeared, after the outbreak. The findings confirm and add to existing knowledge on the varied origins, correlates, and impacts of stigma. They also highlight the synergistic roles of inconsistent health policy responses and risk miscommunication by the media in rapidly amplifying stigma toward an unfamiliar illness. While recognizing the intrinsically stigmatizing nature of public health measures to control SARS, we recommend that a consistent inter-sectoral approach is needed to minimize stigma and to make an effective health response to future outbreaks.
