Design: Cross-sectional study.Setting: Cognition clinic and memory clinic of a public hospital in Hong Kong.Participants: A total of 272 participants (dementia, n=130; mild cognitive impairment, n=93; normal controls, n=49) aged 60 years or above were assessed using HK-MoCA. The HK-MoCA scores were validated against expert diagnosis according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed) criteria for dementia and Petersen's criteria for mild cognitive impairment. Statistical analysis was performed using receiver operating characteristic curve and regression analyses. Additionally, comparison was made with the Cantonese version of Mini-Mental State Examination and Global Deterioration Scale. Results:The optimal cutoff score for the HK-MoCA to differentiate cognitive impaired persons (mild cognitive impairment and dementia) from normal controls was 21/22 after adjustment of education level, giving a sensitivity of 0.928, specificity of 0.735, and area under the curve of 0.920. Moreover, the cutoff to detect mild cognitive impairment was 21/22 with a sensitivity of 0.828, specificity of 0. • It is a reasonably good screening tool for mild cognitive impairment with comparable efficacy with the Cantonese version of Mini-Mental State Examination (MMSE). Implications for clinical practice or policy • HK-MoCA is brief and feasible to conduct in the clinical setting, and can be completed in less than 15 minutes.• HK-MoCA provides an attractive screening instrument in place of MMSE which has ceiling effect and needs to be purchased due to copyright issues.

This study examined the impact of attachment avoidance on relationship outcomes. A “cultural fit” hypothesis, which states that individual differences in personality should be associated with relationship problems if they encourage patterns of behavior that are incongruent with cultural norms, was investigated. It was hypothesized that attachment avoidance, a style of relationship in which emotional distance and independence are emphasized, would be more strongly associated with relationship problems in more collectivist societies (Hong Kong and Mexico) than in a more individualist one (the United States), given the greater emphasis placed on closeness and harmony in relationships in collectivist cultures. As predicted, associations between avoidant attachment and relationship problems were stronger in Hong Kong and Mexico than in the United States.
