The Montreal Cognitive Assessment (MoCA) has started to be used in longitudinal investigations to measure cognition trends but its measurement properties over time are largely unknown. This study ...aimed to examine the longitudinal measurement invariance of individual MoCA items.
We used four waves of data collected between 2014 and 2017 from a cohort study on health and well-being of older adults from twelve public housing estates in Hong Kong. We identified people aged 65 years or older at baseline who answered the MoCA items across all time points and had a valid indicator of educational level. A total of 1028 participants were included. We applied confirmatory factor analysis of ordinal variables to examine measurement invariance of the Chinese (Cantonese) MoCA (version 7.0) items across four time points, stratified by educational level, where invariant items were identified by sequential model comparisons.
Four items exhibited a lack of measurement invariance across the four time points in both education groups (Clock Hand, abstraction, Delayed Recall, and Orientation). The items Cube and Sentence Repetition lacked longitudinal measurement invariance only in the "some education" group and the items Clock Shape and Clock Number only in the "no education" group. However, accounting for the lack of measurement invariance did not substantially affect classification properties for major neurocognitive disorder and mild cognitive impairment.
Our findings support using MoCA to assess changes in cognition over time in the study population while calling for future research in other populations.

There is an ample body of literature examining the experiences and outcomes of peer support services for mental health recovery in western countries. However, formal peer support is only recently ...adapted and piloted to alleviate depression among older people, and little is known about how the peer-to-peer model might be lived out in the older Chinese population. This qualitative study investigated peer supporters' (PS) perspectives of their roles and experiences of rendering formal peer support to community-dwelling older adults at risk of or living with depression in Hong Kong.
The study adopted a qualitative design. Five semi-structured focus groups were conducted with 27 trained peer supporters between ages 54-74 (21 females and 6 males) who had provided peer-to-peer support to older adults at risk of or living with depression in the community for at least 12 months. Thematic analysis was employed to derive content and meanings from the focus group transcripts.
Participants' mean age was 61.9 years; two-thirds of them were retired and the rest still engaged in part-time or full-time employment. Four themes were identified in relations to the roles and experiences in rendering the peer support services: (1) peerness in health and age-related lived experiences; (2) companionship, social and emotional ties beyond formal support; (3) meaningful roles to facilitate older people's functional ability; and (4) hopes and actions against the undesirable outcomes of aging. Being a PS might provide meaningful roles for persons in transition to or living in late adulthood, and enable community-dwelling older adults with depression to maintain functional ability. On the other hand, defining the concept of 'peer' beyond the shared experience of mental distress, ensuring a healthy boundary between the peers and the service users, maintaining a careful balance between time-limited formal support and stable social ties, and providing self-management training and on-going support appear crucial.
This study of PS' perspectives and experiences offer insights into the age-specific dimension of the peer relationship. Despite the promising effects it might offer, careful implementation of peer support among older adults is warranted to safeguard against the ensuing loss of meaningful social ties and the potential emotional distress.
There is accumulating evidence for the efficacy of nonpharmacological multimodal stimulation interventions in maintaining cognition and improving quality of life in people with mild-to-moderate ...dementia. However, the complex nature of these interventions limits their application in practice and research. We report here the design and development of a culturally appropriate framework, the Six Arts, to guide delivery of multimodal interventions in a Chinese community.
The Six Arts are a core set of Confucian philosophy comprising 6 disciplines of rites, music, archery, charioteering, literacy, and numeracy. They correspond to major mind-body functional domains of social functioning; music and rhythm; visuospatial and fine motor skills; kinesthetic and gross motor skills; language and verbal skills; and executive function. Using Six Arts as a framework, we mapped theoretical principles and evidence-based nonpharmacological interventions of cognitive stimulation, physical exercise, and social activities against the 6 functional domains. From 2011, we field-tested the use of Six Arts in structuring intervention programs in 263 people in a dementia day center in Hong Kong.
The Six Arts was operationalized through the development of an intervention activity database, a scoring system for intensity level, and a service delivery model for application in dementia day centers.
Six Arts can be used as framework for structuring nonpharmacological group intervention programs in dementia day center in a metropolitan Chinese city. Its cultural appropriateness may facilitate communication and shared decision making with families with dementia in communities influenced by Confucian philosophy.
ObjectiveLoneliness is a significant and independent risk factor for depression in later life. Particularly in Asian culture, older people may find it less stigmatising to express loneliness than ...depression. This study aimed to adapt a simple loneliness screen for use in older Chinese, and to ascertain its relevance in detecting depressive symptoms as a community screening tool.Design, setting and participantsThis cross-sectional study was conducted among 1653 older adults aged 60 years or above living in the community in Hong Kong. This was a convenient sample recruited from four local non-governmental organisations providing community eldercare or mental healthcare services. All data was collected by trained social workers through face-to-face interviews.MeasuresLoneliness was measured using an adapted Chinese version of UCLA 3-item Loneliness Scale, depression symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9), and social support with emotional and instrumental support proxies (number of people who can offer help). Basic demographics including age, gender, education and living arrangement were also recorded.ResultsThe average loneliness score was 3.9±3.0, and it had a moderate correlation with depressive symptoms (r=0.41, p<0.01). A loneliness score of 3 can distinguish those without depression from those with mild or more significant depressive symptoms, defined as a PHQ-9 score of ≥5 (sensitivity 76%, specificity 62%, area under the curve=0.73±0.01). Loneliness explained 18% unique variance of depressive symptoms, adding to age, living arrangement and emotional support as significant predictors.ConclusionA 3-item loneliness scale can reasonably identify older Chinese who are experiencing depressive symptoms as a quick community screening tool. Its wider use may facilitate early detection of depression, especially in cultures with strong mental health stigma.Trial registration numberClinicalTrials.gov NCT03593889
Depression symptoms are significantly associated with an increased risk of cardiovascular disease (CVD). However, understanding of the magnitude of the association between depression duration and ...risk of CVD is limited. Therefore, we aimed to assess whether a longer duration of exposure to depression is associated with a higher risk of new-onset CVD.
We conducted a territory-wide retrospective cohort study among patients (≥ 10 years old) with depression diagnosed between January and December 2014 in Hong Kong. The observation period spanned January 1, 2014, to December 31, 2019, and all participants had no CVD at baseline. Incidence of CVD was calculated. We used Cox proportional hazard regression to adjust confounders and estimate hazard ratios of CVD risk.
Among 11,651 participants with depression, 1306 (11.2%) individuals developed CVD. Multi-adjusted models showed individuals with depression duration of 2–5 years (Hazard Ratios HRs: 1.38 95% confidence interval (CI): 1.19–1.60) and ≥6 years (1.45 1.25–1.68) had a significantly escalated risk of developing CVD, compared to those with depression within one year. Stratified analyses indicated that the association was prominent in women and those under 65 years old.
Lack of depression severity information and the small sample size in some subgroup analyses.
Longer exposure to depression is associated with significant increased risk of CVD. The interplay between mental and vascular health emphasizes the need for CVD prevention in patients with long-term depression.
•More than one-tenth of people with depression developed cardiovascular disease in Hong Kong during a 5.5-year follow-up.•The association between depression duration and cardiovascular disease was dose dependent.•The dose dependent relationship was prominent in women and people under 65 years.
Preferences for aging-in-place are unclear among low-income elderly Chinese city-dwellers, who are more likely to be geographically bound, to have little care support, but possess strong filial ...values and family cohesiveness. This study investigated the preferences for aging-in-place and its contributing neighborhood factors among low-income Chinese elderly in a metropolitan city.
We conducted interviews with 400 older people residing in public housing estates in Hong Kong.
The majority of low-income elderly persons (80.4%) prefer to age in place even if their health and functioning has deteriorated beyond independent living. Logistic regression showed that (a) having very low income (<HK$2,000/month) and not receiving means-tested welfare predicted lower preference for this option odd ratios (OR) = 0.27; and (b) having medical facilities within reach (OR =9.02); and (c) an elderly center in the area (OR = 2.98) were associated with a preference for aging in place, after controlling for demographic, and functioning characteristics.
Low-income elderly Chinese city-dwellers prefer to age in place, given appropriate neighborhood support. These findings can be interpreted in light of Lawton's ecological theory of aging and suggest a service model similar to the Naturally Occurring Retirement Community with Supportive Service Programs.
Background:
Bridging scores generated from different cognitive assessment tools is necessary to efficiently track changes in cognition across the continuum of care. This study linked scores from the ...Montreal Cognitive Assessment-5 min (MoCA 5-min) to the interRAI cognitive Performance Scale (CPS), commonly adopted tools in clinical and long-term care settings, respectively.
Methods:
We included individual-level data from persons who participated in a home- and community-based care program for older people with mild impairment in Hong Kong. The program used the interRAI-Check Up instrument for needs assessment and service matching between 2017 and 2020. Each participant's cognitive performance was assessed using CPS, CPS Version 2 (CPS2), and MoCA 5-min. We performed equipercentile linking with bivariate log-linear smoothing to establish equivalent scores between the two scales.
Results:
3,543 participants had valid data on both scales; 66% were female and their average age was 78.9 years (SD = 8.2). The mean scores for MoCA 5-min, CPS, and CPS2 were 18.5 (SD = 5.9), 0.7 (SD = 0.7), and 1.3 (SD = 1.1), respectively. A CPS or CPS2 score of 0 (intact cognition) corresponds to MoCA 5-min scores of 24 and 25, respectively. At the higher end, a CPS score of 3 (moderately impaired) and a CPS2 score of 5 (moderately impaired Level-2) corresponded to MoCA 5-min scores of 0 and 1, respectively. The linking functions revealed the floor and ceiling effects that exist for the different scales, with CPS and CPS2 measuring more-severe cognitive impairment while the MoCA 5-min was better suited to measure mild impairment.
Conclusions:
We provided score conversions between MoCA 5-min and CPS/CPS2 within a large cohort of Hong Kong older adults with mild physical or cognitive impairment. This enabled continuity in repeated assessment with different tools and improved comparability of cognitive scores generated from different tools from diverse populations and research cohorts.
Objective: This study examined the moderator role of intergenerational family capital on the relationship between community social capital and life satisfaction of older Chinese adults.
Method: The ...data were derived from a quota sampling of 372 older adults aged 60 and above, who were interviewed at four districts in Hong Kong in 2011. Multiple group analysis was employed to examine the proposed model.
Results: For the low family capital group, community social capital was found to be a significant predictor of life satisfaction, even when the well-known covariates were controlled. However, the association between community social capital and life satisfaction was statistically non-significant among the high family capital group.
Discussion: The findings highlighted the interplay between community social capital and intergenerational family capital, which supported community social capital replacement theory in understanding the mechanism linking social capital to life satisfaction in older age in a Chinese context. Community social capital can play a compensatory role in maintaining the mental health of older people. It is particularly important for older adults who lack family support and/or suffer from social isolation and loneliness in local communities.

A growing body of research suggests an association between attention deficit hyperactivity disorder (ADHD) and allergic disorders, but little work has been done to explore the role of external ...factors such as parental smoking at home in the development of comorbid ADHD and allergic disorders. This study aimed to examine the association between allergic diseases and ADHD adjusted for exposure to parental smoking at home in early adolescents. We recruited 250 male (41.7%) and 350 female (58.3%) adolescents (mean SD age, 13.29 0.52 years) via chain-referral sampling. Their ADHD symptoms were assessed by the parent proxy-report version of the Chinese Strengths and Weaknesses of Attention-Deficit/Hyperactivity-symptoms and Normal-behaviours (SWAN) rating scale. Data on the participants’ history of clinician-diagnosed allergic diseases, family socio-demographics, and parental smoking habit were collected using a parent-completed questionnaire. Regression analyses were performed to examine the associations of interest. The levels of ADHD symptoms were comparable between allergic and non-allergic participants after controlling for child and family demographics and parental smoking at home. Notably, the risk of probable ADHD was particularly high in participants with food allergies (odd ratio = 4.51, p = 0.011) but not in those with allergic rhinitis after adjusting for parental smoking at home. Our findings suggest that second-hand smoke exposure at home is a potential risk factor underlying the link between ADHD and allergic diseases. Current management guidelines should emphasize the importance of early identification and cessation of tobacco smoke exposure for prevention of comorbidity of ADHD and allergic disorders.

Objectives
To examine the neuropsychological and clinical profile of help‐seekers in an early‐detection community dementia program and to explore any relationship between profiles and time to seek ...help.
Design
Cross‐sectional.
Setting
Early‐detection community dementia program.
Participants
Help‐seekers (N = 1,005) with subjective cognitive complaints or complaints from an informant.
Measurements
Neurocognitive testing, including the Cantonese Mini‐Mental State Examination (MMSE), Clock Drawing Test, Digit Span, and Fuld Object Memory Evaluation and other clinical and functioning assessments, including the Clinical Dementia Rating (CDR), activities of daily living (ADLs), instrumental ADLs (IADLs), and depressive symptoms. Time since the person or an informant reported that they first noticed symptoms.
Results
Eighty‐six percent of help‐seekers had at least very mild dementia (CDR score ≥0.5). Cognitive performance was moderately impaired (mean MMSE score 18.4 ± 6.1). They required some assistance with IADLs, had very mild ADL impairments, and had few depressive symptoms. Median time to seek assessment was 12 months (interquartile range 7–30 months) according to the person or the informant (an adult child in 75% of the sample). Using the median‐split method, time to seek assessment was classified as early (0–12 months) and late (>12 months). Worse cognitive and IADL performance but not ADL performance or depressive symptoms were observed in late than in early help‐seekers. Longer time intervals between symptom recognition and early assessment showed a trend of further impairments on all measures except ADLs.
Conclusion
A time interval of more than 12 months between symptom recognition and early assessment appears to be associated with worse cognitive function upon presentation.
