Notwithstanding the oldest-old cohort being the fastest-growing population in most ageing societies, characterizing successful ageing in adults of advanced age, such as nonagenarians and centenarians, remains challenging. This study investigated the successful ageing subphenotypes using the data from Hong Kong Centenarian Study 2. Between April 2021 and September 2022, 146 family caregivers of community-dwelling older adults aged 95 or above were interviewed by phone. Latent class analysis identified three classes-Overall Frail (46.6%) with poor mobility, cognitive and functional health, Nonambulant (37.0%) but good functional health, and Robust (16.4%) with overall good health-from 11 indicators based on caregivers' reports. Although we found a low prevalence of fulfillment of all indicators of successful ageing, our findings will help care professionals appreciate the heterogeneity underlying partial successful ageing in this vulnerable cohort for segmented and targeted healthy longevity interventions.

According to the broaden-and-build theory, positive emotions can broaden our awareness and build psychological resources, which leads to better psychological outcomes. Previous studies demonstrated that hope partially mediates the association between positive emotions and life satisfaction in college students. Yet, there has no similar model been tested among older adults. The objective of the current study was to evaluate the mediating role of hope agency and pathways in the association between positive emotions and life satisfaction. Three hundred and forty-one Chinese community-dwelling older adults (mean = 70.83, SD = 9.16) were asked to complete a survey questionnaire comprising measures assessing positive emotions, hope, life satisfaction, and other sociodemographic variables. Results showed that hope agency, but not hope pathways, partially mediated the relationship between positive emotions and life satisfaction. We discussed the importance of these initial findings concerning positive emotions and hope as predictors of life satisfaction in the older adult population.

The global coronavirus disease 2019 (COVID-19) crisis has exerted significant psychological impacts on university students who have faced drastic changes in the learning mode and suspension of classes. Despite these challenges, many students maintained subjective well-being. In this study, we examined the role of "hope" as a potential protector to maintain their subjective well-being when facing adversity during this global crisis. Specifically, we explored the mediating role of two hope components (agency thinking and pathways thinking) on the association of positive emotions and life satisfaction among Chinese university students. We conducted an online survey at a local university and recruited a total of 315 undergraduates from the humanities, creative arts, and social sciences programs through convenience sampling. Participants confirmed their informed consent and completed a set of self-administered questionnaires measuring positive emotions, hope, life satisfaction, and demographic variables. The results of mediation testing indicated that, during a global crisis such as COVID-19, positive emotions indirectly influenced life satisfaction through agency thinking rather than pathways thinking. The findings highlight the importance of agency thinking among Chinese university students in adverse situations and provide valuable insights for psychological interventions during a crisis. The article concludes by discussing possible explanations and implications of the findings in a post-pandemic world.

Nursing students are at risk for high-stress levels and psychological distress. Limited longitudinal studies have been conducted examining factors associated with stress levels and psychological distress of nursing students in their course of study. The purpose of this study was to examine the levels of stress and corresponding stressors, particularly those predicting psychological distress, among nursing students over their 5 years of study. A longitudinal design, using questionnaires and focus group interviews of a single cohort of nursing students in Hong Kong and following them over their 5 years of training. The Stressors in Nursing Students Scale-Chinese version and the Chinese version of General Health Questionnaire-12 were used to assess stress levels and psychological distress, respectively. Ninety-seven participants completed the questionnaires 5 times. Quantitative findings revealed that the overall stress levels of the nursing students increased over 5 years (from mean = 3.08 to 3.33), with the highest levels in the second wave (mean = 3.33). Nursing students experienced higher stress during years 2 (p = 0.006) and 4 (p = 0.037). Psychological distress was the highest in year 3 (sum score = 18.47) (p = 0.002) but declined from year 4 (p < 0.001). Thematic analysis revealed that academic performance issues, coping challenges, unfavorable learning environments, relationships were identified as the stressors. However, nursing students also used positive coping strategies to pursue success and seek support. This study suggests that the year of study is a significant predictor of stress levels among nursing students, especially during the first and senior years due to heavy academic workload. Psychological distress was observed among nursing students, and those who worked more part-time jobs tended to report higher levels of distress. The junior year was associated with higher levels of distress related to financial and time-related stress, while academic and personal problems were more prevalent during the senior year.

Existing image-based rendering methods usually adopt depth-based image warping operation to synthesize novel views. In this paper, we reason the essential limitations of the traditional warping operation to be the limited neighborhood and only distance-based interpolation weights. To this end, we propose content-aware warping, which adaptively learns the interpolation weights for pixels of a relatively large neighborhood from their contextual information via a lightweight neural network. Based on this learnable warping module, we propose a new end-to-end learning-based framework for novel view synthesis from a set of input source views, in which two additional modules, namely confidence-based blending and feature-assistant spatial refinement, are naturally proposed to handle the occlusion issue and capture the spatial correlation among pixels of the synthesized view, respectively. Besides, we also propose a weight-smoothness loss term to regularize the network. Experimental results on light field datasets with wide baselines and multi-view datasets show that the proposed method significantly outperforms state-of-the-art methods both quantitatively and visually.

The development of resident safety culture in nursing homes (NH) represents a major challenge for governments and NH owners, with a requirement for suitable tools to assess safety culture. Indonesia currently lacks suitable safety cultures scales for NH. To evaluate the psychometric properties of the translated Indonesian version of the Nursing Home Survey on Patient Safety Culture (NHSOPSC-INA). This study was a cross-sectional survey conducted using NHSOPSC-INA. A total of 258 participants from 20 NH in Indonesia were engaged. Participants included NH managers, caregivers, administrative staff, nurses and support staff with at least junior high school education. The SPSS 23.0 was used for descriptive data analysis and internal consistency (Cronbach's alpha) estimation. The AMOS (version 22) was used to perform confirmatory factor analysis (CFA) on the questionnaire's dimensional structure. The NHSOPSC CFA test originally had 12 dimensions with 42 items and was modified to eight dimensions with 26 items in the Indonesian version. The deleted dimensions were 'Staffing' (4 items), 'Compliance with procedure' (3 items), 'Training and skills' (3 items), 'non-punitive response to mistakes' (4 items) and 'Organisational learning' (2 items). The subsequent analysis revealed an accepted model with 26 NHSOPSC-INA items (root mean square error of approximation = 0.091, comparative fit index = 0.815, Tucker-Lewis index = 0.793, CMIN = 798.488, df = 291, CMIN/Df = 2.74, GFI = 0.782, AGFI = 0.737, p < 0.0001) and a factor loading value of 0.538-0.981. Expert feedback confirmed the relevance of the instrument items (content validity index [CVI] = 0.942). The modified NHSPOSC-INA model with eight dimensions (26 items) fits the data set in the context of Indonesian NH services. The NHSPOSC-INA is a valid and reliable instrument for assessing staff perceptions of NH resident safety culture in Indonesia. The questionnaire can now be used to evaluate interventions for resident safety in Indonesian NH.

Image style transfer has attracted widespread attention in the past years. Despite its remarkable results, it requires additional style images available as references, making it less flexible and inconvenient. Using text is the most natural way to describe the style. Text can describe implicit abstract styles, like styles of specific artists or art movements. In this work, we propose a text-driven style transfer (TxST) that leverages advanced image-text encoders to control arbitrary style transfer. We introduce a contrastive training strategy to effectively extract style descriptions from the image-text model (i.e., CLIP), which aligns stylization with the text description. To this end, we also propose a novel cross-attention module to fuse style and content features. Finally, we achieve an arbitrary artist-aware style transfer to learn and transfer specific artistic characters such as Picasso, oil painting, or a rough sketch. Extensive experiments demonstrate that our approach outperforms the stateof-the-art methods. Moreover, it can mimic the styles of one or many artists to achieve attractive results, thus highlighting a promising future direction.

Social networks play a vital role in facilitating late-life health and well-being. The current research sought to examine the psychometric properties of the abbreviated Lubben Social Network Scale (LSNS-6) among community-dwelling Hong Kong Chinese older adults and to explore the association between social network and well-being indicators such as life satisfaction, functional social support, loneliness and anxiety. We administered the LSNS-6 scale to 324 older adults (mean = 71.70, SD = 8.58, range: 58-95). We performed confirmatory factor analysis (CFA) to confirm the construct validity. Cronbach's alpha was chosen for internal consistency estimation. Correlational analysis was performed between LSNS-6 scale and other measures to ascertain the convergent validity. The two-factor model of LSNS-6 indicated an adequate fit. The goodness-of-fit index values for the model were χ2 /df = 2.61, CFI = 0.98, RSMEA = 0.07, SRMR = 0.05. The internal consistency of the scale was α = 0.75. It also demonstrated good construct validity in measuring the social network and acceptable convergent validity to other measures. The LSNS-6, according to current findings, can be a valid reference to the social network of Hong Kong older adults, enabling researchers and clinicians to investigate and develop further corresponding remedies for those in need.

PurposeTo explore older adults’ perceived relationship quality with migrant domestic workers (MDWs) and examine the correlation between older adult/MDW (O-M) relationship quality and loneliness of community-dwelling older adults. Materials and methodsIn this cross-sectional study, older adults living with MDWs were conveniently recruited from neighbourhood elderly centers in Hong Kong. Loneliness and O-M relationship quality were assessed by the 6-item De Jong Gierveld Loneliness Scale and the mutuality scale, respectively. Older adults’ demographic and functional characteristics, and MDW's nationality, spoken language and years of service in the dyad were also collected. Hierarchical multiple regression analyses were conducted to examine the contributions of 1) demographic variables and functional status, 2) MDW characteristics, 3) perceived social network and 4) perceived O-M relationship quality on loneliness. ResultsThe 178 participants [mean age 83.44 (SD 7.05 years); 155 (87.1%) women and 23 men (22.9%)] were socially lonely (1.07 ± 1.15) and close to being lonely overall (1.90 ± 1.68), and emotionally (0.84 ± 0.97). The mean O-M relationship quality was poor (1.42 ± 0.79), which was significantly correlated with overall (β= -0.33, 95% CI: -0.65 to -0.01, P value = 0.045), and social (β= -0.24, 95% CI: -0.46 to -0.01, P value = 0.04) loneliness, but not significantly correlated to emotional loneliness. ConclusionBetter perceived O-M relationship quality is correlated with a lower level of loneliness among older adults. Strategies to improve O-M relationship quality may alleviate loneliness among older adults.

IntroductionThe fifth wave of COVID-19 has significantly overburdened the health care system in Hong Kong. Health care professionals, particularly nurses continue to experience significant levels of psychological distress when tackling this ongoing outbreak. Yet, no study has explored the psychological experiences of nurses during the most recent outbreak of the highly transmissible Omicron variant in Hong Kong. The aim of this qualitative study was to explore the psychological distress experienced by nurses during the fifth wave of the COVID-19 pandemic in Hong Kong.MethodsTwenty-two nurses (14 female and 8 male nurses; average age, 36.7 ± 8.5 years) were recruited to attend the one-to-one semi-structured telephone interviews from June to July, 2022. Data were analyzed using thematic analysis.ResultsFour main themes emerged from the interview: (1) Intense fear, worry, and anxiety; (2) Feeling worn out and psychologically distress; (3) Impact on psychosocial and physical health; and (4) Limited options to cope with psychological distress during the difficult times.DiscussionOur study findings may provide concerned stakeholders with useful insights into reducing the psychological distress experienced by nurses in Hong Kong. Offering psychological support is of paramount importance to address the unmet psychological needs of nurses and reduce their psychological distress during the pandemic, particularly when they are working under high levels of workplace stress.
