ABSTRACT: PURPOSE: The study aimed to explore the gender difference in using colorectal cancer (CRC) tests among Chinese aged 50 years or over. METHODS: A cross-sectional study was conducted in 2004 Chinese older adults through anonymous telephone survey which covered socio-demographic variables, health status, use of complementary therapy, health-related perceptions and use of CRC tests. RESULTS: The uptake rate of flexible sigmoidoscopy (FS)/colonoscopy was 14% for males and 10% for females, with males significantly more likely to have had the test after adjusting for their differences in socio-demographics, health status, use of complementary therapies, health-related perceptions and recommendation received from health professionals (adjusted OR = 1.5, 95% CI: 1.1-2.0, p = 0.005). The uptake of fecal occult blood test was nearly the same (19%) for both genders. Further interaction analyses indicates that the effect of a family history of cancer on the uptake of a FS/colonoscopy is significantly weaker in males than in females (the interaction odds ratio = 0.4, 95% CI: 0.2-0.8, p = 0.011), whereas a male perceived that visiting a doctor is good for health will be more likely to have an uptake of a FS/colonoscopy than a female with such perception (the interaction odds ratio = 2.1, 95% CI: 1.1-3.8, p = 0.018). CONCLUSIONS: The uptake of CRC tests was low in this average-risk population. More effort is needed to educate the public about the importance and benefits of CRC tests. In view of the gender differences in some determinants of FS/colonoscopy uptake, particular attention should be given to develop gender-specific strategies to improve the rate.

ABSTRACT: OBJECTIVE: The decisional conflict scale (DCS) measures the perception of uncertainty in choosing options, factors contributing to decision conflict and effective decision making. This study examined the validity and reliability of the Chinese version of the DCS in Hong Kong Chinese women deciding breast cancer (BC) surgery. METHOD: A Chinese version of the 16-item DCS was administered to 471 women awaiting initial consultation for BC diagnosis. Confirmatory factor analysis (CFA) assessed the factor structure. Internal consistency, and convergent and discriminant validities of the factor structure were assessed. RESULTS: CFA revealed the original factor structure of the DCS showed poor fit to this sample. Exploratory factor analysis revealed an alternative three-factor structure, Informed and Values Clarity, Uncertainty and Effective Decision and Support, was optimal. Cronbach's alpha ranged from 0.51 to 0.87. Correlations between decision-making difficulties and satisfaction with medical consultation demonstrated acceptable convergent validity. Construct validity was supported by correlations between decision regret and psychological distress. Discriminant validity was supported by differentiation between delaying and non-delaying decision-makers. CONCLUSIONS: The three-factor DCS-14 is a valid and practical measure for assessing decisional conflict in deciding BC surgery. It shows good potential for use in assessing decision satisfaction for women diagnosed with BC.

ABSTRACT: BACKGROUND: Understanding cancer patients' supportive care needs can help optimize health-care systems and inform services development. We therefore examined the prevalence of supportive care needs in Chinese breast (BC) and colorectal cancer (CRC) patients to identify prevalence and correlates of unmet needs. METHODS: We assessed supportive care needs (Supportive Care Needs Survey-Short Form), psychological distress (the Hospital Anxiety and Depression Scale), symptom distress (The Memorial Symptom Assessment Scale-Short Form), and satisfaction with care (Patient Satisfaction Questionnaire) among 210 Chinese BC (97) or CRC (104) outpatient clinic attendees. RESULTS: Breast cancer patients (89.7%) reported more unmet needs (χ(2) = 4.409, p = 0.027), but both CRC and BC samples ranked unmet needs prevalence similarly, with health system and information needs reported as the most common. Younger patients reported higher health system and information and sexuality needs. After multivariate adjustment, the strength of unmet needs did not differ by cancer type. Unmet psychological, physical and daily living, and sexuality needs were positively associated with greater symptom distress. Greater health system information needs were associated with high global distress and low depression scores, whereas greater psychological needs were associated with higher anxiety scores. CONCLUSIONS: Hong Kong Chinese BC and CRC patients strongly prioritized needs related to health systems and information provision. Symptoms and psychological distress were associated with unmet needs, reflecting a service shortfall in symptom management. Improving care provision by optimizing communication and clinic organization can better prepare cancer patients for their rehabilitation and improve symptom control.

ABSTRACT: We examined degree and determinants of change in body image and sexuality over the first year following breast cancer diagnosis to differentiate body image and sexuality trajectories, and then explored if differences in trajectories predicted 6 years' psychosocial outcomes. 363/405 (90%) Chinese women receiving surgery for BC were assessed at 5-days (Baseline), 1-month, 4-months, and 8-months post-surgery. Psychological distress, treatment decision making (TDM) difficulties, satisfaction with treatment outcome, optimism, and self-efficacy were assessed at Baseline. Self-image and sexuality were recorded at each follow-up assessment. Latent growth mixture modeling identified trajectories of self-image and sexuality. Multinominal logistic regression identified factors predicting trajectory patterns. Six years later 211/363 (58%) of the original patients were successfully traced and their psychosocial status assessed. Three distinct trajectories of self-image and sexuality were identified: high-stable, recovery, and high-deteriorating. Most women (64% self-image; 58% sexuality) showed stable levels of self-image and sexuality scores. TDM difficulties, satisfaction with treatment outcomes, physical symptom and psychological distress predicted trajectory patterns. Self-image trajectories over the first year diagnosis predicted 6-years psychosocial outcomes. Women with high-stable level of self-image had the best 6-year self-image and sexuality; women with initial low level of self-image had significantly greater long-term psychological distress. Low TDM difficulties and high treatment outcome satisfaction predicted high and stable self-image and sexuality. Type of surgery showed little impacts on self-image and sexuality. Self-image during acute illness phase predicted long-term outcomes. Interventions should focus on minimizing self-image decrement.

ABSTRACT: This secondary longitudinal analysis describes distinct quality of life trajectories during eight months of radiation therapy (RT) among patients with nasopharyngeal cancer (NPC) and examines factors differentiating these trajectories.
253 Chinese patients with NPC scheduled for RT were assessed at pre-treatment, and 4 months and 8 months later on QoL (Chinese version of the FACT-G), optimism, pain, eating function, and patient satisfaction. Latent growth mixture modelling identified different trajectories within each of four QoL domains: Physical, Emotional, Social/family, and Functional well-being. Multinomial logistic regression compared optimism, pain, eating function, and patient satisfaction by trajectories adjusted for demographic and medical characteristics.
We identified three distinct trajectories for physical and emotional QoL domains, four trajectories for social/family, and two trajectories for functional domains. Within each domain most patients (physical (77%), emotional (85%), social/family (55%) and functional (63%)) experienced relatively stable high levels of well-being over the 8-month period. Different Physical trajectory patterns were predicted by pain and optimism, whereas for Emotion-domain trajectories pain, optimism, eating enjoyment, patient satisfaction with information, and gender were predictive. Age, appetite, optimism, martial status, and household income predicted Social/family trajectories; household income, eating enjoyment, optimism, and patient satisfaction with information predicted Functional trajectories.
Most patients with NPC showed high stable QoL during radiotherapy. Optimism predicted good QoL. Symptom impacts varied by QoL domain. Information satisfaction was protective in emotional and functional well-being, reflecting the importance in helping patients to establish a realistic expectation of treatment impacts.

ABSTRACT: Background Women choosing breast cancer surgery encounter treatment decision-making (TDM) difficulties, which can cause psychological distress. Decision Aids (DAs) may facilitate TDM, but there are no DAs designed for Chinese populations. We developed a DA for Chinese women newly diagnosed with breast cancer, for use during the initial surgical consultation.Aims Conduct a pilot study to assess the DA acceptability and utility among Chinese women diagnosed with breast cancer.Methods Women preferred the DA in booklet format. A booklet was developed and revised and evaluated in two consecutive pilot studies (P1 and P2). On concluding their initial diagnostic consultation, 95 and 38 Chinese women newly diagnosed with breast cancer received the draft and revised draft DA booklet, respectively. Four-day post-consultation, women had questionnaires read out to them and to which they responded assessing attitudes towards the DA and their understanding of treatment options.Results The original DA was read/partially read by 66/22% (n = 84) of women, whilst the revised version was read/partially read by 74/16% (n = 35), including subliterate women (χ2 = 0.76, P = 0.679). Knowledge scores varied with the extent the booklet was read (P1: F = 12.68, d.f. 2, P < 0.001; P2: F = 3.744, d.f. 2, P = 0.034). The revised, shorter version was graphically rich and resulted in improved perceived utility, [except for the ‘treatment options’ (χ2 = 5.50, P = 0.019) and ‘TDM guidance’ (χ2 = 8.19, P = 0.004) sections] without increasing anxiety (F = 0.689, P = 0.408; F = 3.45, P = 0.073).Conclusion The DA was perceived as acceptable and useful for most women. The DA effectiveness is currently being evaluated using a randomized controlled trial.

ABSTRACT: Background
Delayed consultation for potential cancer symptoms influences treatment outcomes and remains problematic. Delay components (Appraisal versus Utilization) and respective associations are poorly understood.Methods
Eligible participants were Cantonese-speaking Chinese women, ≥21 years old, with self-discovered breast symptoms, recruited in surgical clinics before their first consultation, and naïve to their diagnosis. Overall 425/433 (98%) women completed a questionnaire on psychosocial, demographic and medical factors, how and when women discovered their breast symptom(s), and their subsequent decision making; 135/425 women (32%) were later diagnosed with breast cancer.ResultsTwenty-two per cent of women delayed >3 months before consultation. Women with breast cancer (28%) more often had prolonged delay than women with benign disease (19%). Attributing symptom to a non-cancerous condition, low fear on symptom discovery, not disclosing symptoms to others, and no prior breast symptom history predicted prolonged (>60 days) Appraisal Delay. Low fear on symptom discovery, seldom thinking about the symptom, and consultation for other reasons predicted prolonged (>14 days) Utilization Delay. Factors predicting Appraisal and Utilization Delays differentiated cancer from non-cancer groups.Conclusions
Indecision over symptom meaning comprised the main component of Appraisal and Total Delay, suggesting that educational strategies targeting atypical symptoms should reduce avoidable delays following self-discovered breast symptoms. Copyright © 2011 John Wiley & Sons, Ltd.

ABSTRACT: The comparison of psychosocial needs across different cultural settings can identify cultural and service impacts on psychosocial outcomes. We compare psychosocial needs in Hong Kong Chinese and German Caucasian women with breast cancer. Completed questionnaires were collected from 348 Chinese and 292 German women with breast cancer for assessing unmet psychosocial needs (Supportive Care Needs Survey Short Form), psychological distress (the Hospital Anxiety and Depression scale), and listed physical and psychological symptoms. Only 11% of the participants reported not needing help for any of the 34 items. More German (14%) than Chinese women (8%) reported no unmet needs (χ(2) = 6.16, P = .013). With both samples combined, the Health System and Information domain unmet needs were the most prevalent, apart from one Psychological need domain item, "Fear about the cancer spreading." Chinese and German samples differed significantly in prevalence and patterns of unmet psychosocial needs. Multivariate adjustment for demographic, clinical, and sample characteristics, psychological distress, and symptoms showed that significantly greater unmet Health system and Information, and Patient care and support domain needs, associated with the presence of symptoms (β = .232, P < .001), high HADS Anxiety (β = .187, P < .001), higher education attainment (β = .120, P = .002), and Chinese sample membership (β = .280, P < .001). Greater unmet Psychological, Physical and Daily Living, and Sexuality domain needs were associated with the presence of symptoms, psychological distress, and German group membership, among others. German women reported more anxiety (t = 10.45, P < .001) and depression (t = 3.71, P < .001). In post hoc analyses, German, but not Chinese women reporting greater anxiety and depression had greater unmet Psychological and Sexuality domain needs (P < .001). It can be concluded that culture-specific differences in supportive care needs exist. Hong Kong Chinese women prioritize needs for information about their disease and treatment, whereas German Caucasian women prioritize physical and psychological support. Planning for cancer supportive care services or interventions to reduce unmet needs must consider cultural and/or health service contexts.

ABSTRACT: To explore how initial trajectories of distress experienced during the first year following diagnosis with early-stage breast cancer (ESBC) relate to subsequent long-term(6 years) psychosocial outcomes.
285/303 Chinese women recruited 1-week post-surgery for predominantly ESBC were assessed for distress with the Chinese Health Questionnaire at 1, 4, and 8 months later.Latent growth mixture modeling revealed four distinct distress trajectories during the first 8 months following surgery (Lam et al., 2010). Six years later we reassessed 186 of these 285 women, comparing scores on the Hospital Anxiety and Depression Scale, Impact of Events Scale, and Chinese Social Adjustment Scale by first 8 months’ distress trajectory.
Distress trajectories over the first 8 months post-operatively predicted psychosocial outcomes 6 years later. Women with stable low levels of distress over the first 8 months postoperatively(resilient group) had the best 6-year psychosocial outcomes. Women who experienced chronic distress had significantly greater longer-term psychological distress, cancer-related distress, and poorer social adjustment in comparison to women in the resilient group. Women in the recovered or delayed-recovery groups were comparable to those in the resilient group, except for concerns about appearance and sexuality, and self-image.
Women with an illness trajectory characterized by chronic distress over the first 8 months post-operatively had poorest longer-term psychosocial outcomes. Clarification of determinants of chronic distress and means for early identification of at-risk women are needed.This will enable targeted optimization of interventions to prevent and manage chronic distress,improving ESBC rehabilitation efficiency.

ABSTRACT: Little is known about the community psychological and behavioral responses to influenza pandemics.
Using random digit dialing, we sampled 12,965 Hong Kong residents in 13 cross-sectional telephone surveys between April and November 2009, covering the entire first wave of the 2009 influenza A(H1N1) pandemic. We examined trends in anxiety, risk perception, knowledge on modes of transmission, and preventive behaviors.
Respondents reported low anxiety levels throughout the epidemic. Perceived susceptibility to infection and perceived severity of H1N1 were initially high but declined early in the epidemic and remained stable thereafter. As the epidemic grew, knowledge on modes of transmission did not improve, the adoption of hygiene measures and use of face masks did not change, and social distancing declined. Greater anxiety was associated with lower reported use of hygiene measures but greater social distancing. Knowledge that H1N1 could be spread by indirect contact was associated with greater use of hygiene measures and social distancing.
The lack of substantial change in preventive measures or knowledge about the modes of H1N1 transmission in the general population suggests that community mitigation measures played little role in mitigating the impact of the first wave of 2009 influenza A(H1N1) pandemic in Hong Kong.

ABSTRACT: The distinct trajectories of psychological distress over the first year of the diagnosis with breast cancer (BC) and its determinants have not been explored.
285 of 405 Chinese women receiving surgery for BC were assessed at 5-day, 1-month, 4-month, and 8-month post-surgery on measures of psychological distress, optimism, treatment decision-making (TDM) difficulties, satisfaction with treatment outcome, satisfaction with medical consultation, and physical symptom distress. Latent growth mixture modelling identified trajectories of psychological response to BC. Multinominal logistic regression compared TDM difficulties, satisfaction with treatment outcome, satisfaction with medical consultation, optimism, and physical symptom distress, by distress pattern adjusted for age, education, employment status, and stage of disease.
Four distinct trajectories of distress were identified, namely, resilience (66%), chronic distress (15%), recovered (12%), and delayed-recovery (7%). TDM difficulties, optimism, satisfaction with consultation, and physical symptom distress predicted distress trajectories. Psychologically resilient women had less physical symptom distress at early post-surgery compared with women with other distress patterns. Compared with the resilient group, women in the recovered or chronic distress groups experienced greater TDM difficulties, whereas women in the delayed-recovery group reported greater dissatisfaction with the initial medical consultation. Women in the chronic distress group reported greater pessimistic outlook.
Optimism and better early post-operative treatment outcomes predicted resilience to distress. Pre-operative interventions helping women to establish a realistic expectation of treatment outcome may minimize disappointment with treatment outcome and resultant distress, whereas post-operative rehabilitation should focus on symptom management.

ABSTRACT: To examine how Chinese patients with colorectal cancer (CRC) dynamically adapt to diagnosis and treatment and explore how patients evolve and deploy different resources throughout the illness trajectory.
Semi-structured interviews were conducted on a purposive sample of 16 histologically diagnosed Chinese CRC patients about to complete or who had very recently completed all treatment without recurrence. Recorded interviews were transcribed verbatim and analyzed by using grounded theory techniques.
Three major adaptation-related themes were identified: (1) utilization of medical resources, (2) transition of resource utilization, and (3) continuous resistance to demands. Initial prevailing fatalistic views of diagnosis associated predominantly with frequent medical surveillance and with respondents' weighting of treatment and expertise of medical professionals. As treatment progressed, there was a shift toward reliance on personal and social resources to field cancer-related demands concurrent with a gradual distancing from medical care. Upon treatment completion, fatalism re-emerged regarding disease recurrence, which, like diagnosis, was seen as not amenable to individual control, even with close adherence to medical follow-ups and dietary adjustment. Maintaining positive states of mind and good relationships with family and friends were cores strategies respondents adopted to preserve psychological well-being.
Maintenance and enhancement of personal and social resources throughout the CRC trajectory may have considerably more utility than traditional descriptive studies hitherto suggested. Considering personal and social resources within dynamic rather than static models could avoid the pitfall of attributing maladaptive responses to initial dispositions and socioeconomic conditions that are seemingly unalterable and enduring over time.

ABSTRACT: Latent growth curve (LGC) modeling within the framework of structural equation modeling (SEM) is now highly regarded as one of the most powerful and informative approaches to the analysis of longitudinal data (see, e.g., Curran & Hussong, 2003). Whereas LGC modeling enables researchers to test for differences in developmental trajectories across time, conventional repeated measures analyses do not provide this opportunity. Nonetheless, a review of studies reported in most psychology journals reveals scant application of this methodological approach. One possible explanation for this limited use of LGC modeling is a lack of knowledge related to its application. The intent of this article, then, is to address this deficiency by presenting an annotated application of LGC modeling to health psychology data. Based on a sample of 405 Hong Kong Chinese women who recently underwent breast cancer surgery, we walk the readers through SEM modeling procedures that test for differences in both the initial status and rate of change in Psychological Morbidity and Social Adjustment at 1, 4, and 8 months postsurgery. We interpret findings from both a methodological and a substantive perspective.

ABSTRACT: The patterns and determinants of longer-term psychological morbidity in women following breast cancer surgery have not been described for Chinese populations.
Chinese women were assessed at 3-days, 4-months and 8-months following breast surgery, on treatment decision-making difficulty (TDMD), satisfaction with treatment outcome (E-OI), self efficacy (GSeS), optimism (C-LOT-R), consultation satisfaction (C-MISS-R), physical symptom distress (PSD) and psychological morbidity (CHQ-12) and compared using polynomial logistic models. Results: Of 303/405 women providing complete data, 33% received chemotherapy and 26% radiotherapy. GSeS, CLOTR and TDMD scores were moderate. Though the proportion of women meeting psychological morbidity case-criteria declined from 78% (95% Confidence Interval 73-83%) at Baseline to 64% (59-69%) at 8-months, almost 50% (44-54%) of women remained distressed over the 8-month period. After adjustment for demographic and clinical factors, severity of psychological morbidity at 4-months was predicted by PSD, disappointment and higher Baseline CHQ12, and among moderate/severe cases only, greater TDMD and pessimistic outlook. At 8-months, CHQ12 scores were predicted by PSD, Baseline CHQ-12, and difficulties with TDM.
TDM difficulties, early post-surgical psychological and physical symptom distress indicate risk for prolonged distress in Chinese women following breast cancer surgery.

ABSTRACT: Purpose – Avian influenza (AI) has prompted widespread poultry culls and retail changes. Traditional live poultry sales can increase risk for AI virus transmission. Attitudes and risk perceptions regarding these sales influence policy. The purpose of this paper is to report Hong Kong risk perceptions and attitudes regarding live poultry sales and central slaughtering illustrating population reactions to inform policy. Design/methodology/approach – A total of 25 healthy Hong Kong adults completed grounded theory qualitative interviews regarding perceptions of live chicken sales and acceptability of central slaughtering. Taped interviews were transcribed and translated in to English and coded in parallel by the authors working independently, using grounded theory approaches. Findings – The paper finds that hygiene efforts reflected confusion between bacterial contamination and influenza. Hand-transmission was not recognized as a transmission pathway. Opposition to central slaughtering was based on concerns about loss of freshness, flavor, traditions and employment, and meat safety. However, opponents supported policy if it reduced infectious disease risk. Supporters emphasized improved food hygiene. There was considerable scope for further educational efforts. Opposition focused on losses rather than gains, consistent with theory. Supporters emphasized health benefits. AI transmission routes were confused, indicating need for clearer information about personal protective practices. Research limitations/implications – The paper is a qualitative report and awaits confirmation using a quantitative exploration. The data identified a number of barriers to acceptance of a central slaughtering policy, many of which were based on incorrect or limited understanding. Education can help remedy this. Originality/value – The paper describes perceptions among Chinese people towards a public health initiative, revealing many objections are based on misunderstandings.

ABSTRACT: Since 1997, the largest epidemic of highly pathogenic avian influenza (H5N1) ever recorded has caused 172 human and several billion bird deaths. Recently administered questionnaires determined that live poultry exposures have declined by approximately 63% in Hong Kong since 2004 and that, in Vietnam, domestic backyard exposures to poultry are likely more important than retail exposures.

ABSTRACT: to identify factors influencing Chinese women's choices between breast-conserving therapy (BCT), mastectomy (MRM) or MRM followed by breast reconstruction (MRM+R).
of 405/443 Hong Kong Chinese women receiving surgery for early breast cancer who were interviewed one week post-surgery about their pre-surgical consultation, available treatment alternatives, whether their surgeons had indicated a surgical preference, perceived efficacy of the surgical options and considerations influencing their treatment decisions (TDM), 198 (49%) reported they were offered a choice of surgery.
among women offered a choice of surgery, BCT was chosen by 34/43 (79%) of women whose surgeons recommended BCT but by only 34/96 (37%) of women whose surgeons expressed no treatment recommendation. Multivariate adjustment showed women choosing MRM were influenced more by avoiding both cancer recurrence (p = 0.003) and further treatment (p = 0.009) when choosing surgical option than women choosing BCT. In contrast, women choosing MRM+R and BCT, placed more emphasis on appearance (p < 0.001) and body image (p < 0.001) concerns as influencing treatment choice than did women who chose MRM.
survival concerns rather than physical appearance, age and lack of recommendation push Chinese women to choose MRM as BCT is, incorrectly often seen as less efficacious. Recommending BCT increases BCT choice.
