Integrity tests were coded into the types of overt tests, covert tests, biodata, organizational measures, value/moral reasoning/situational judgment tests, integrity-related...

Background and Objectives Studies on longitudinal trajectories of diet and the influence on aging in older adults are limited. We characterized diet quality trajectories over the past 2 decades among adults aged ≥85 years and examined their associations with cognitive and psychosocial outcomes. Research Design and Methods We used data from 861 par...

Introduction: Although successful aging (SA) studies have examined objective indicators such as disease and disability, physical and cognitive function, and social and productive engagement, as well as subjective indicators such as self-rated health, function, and well-being, the interplay among these indicators is rarely studied. We studied SA pr...

Mental ill-health prolongs and complicates other chronic illnesses, which is a major public health concern because of the potential stress it places on health systems. Prevention via active aging and place-based interventions thus became increasingly important with population aging, e.g., through health promotion and age-friendly neighborhoods. How...

Volunteering can be critical to late middle-aged adults’ well-being. Hence, it is essential to understand the antecedents of volunteering in this age group. The present study of Singaporeans aged 50 to 59 (N = 1620) considered 18 volunteering acts and used latent class analysis (LCA) to identify volunteering profiles. The relationships between huma...

The measures against the coronavirus disease (COVID-19) pandemic, such as lockdown, pose a major challenge to those who manage work and caregiving demands. Drawing on social cognitive theory, which emphasizes the critical role of self-referent thought and human agency in overcoming obstacles and striving toward goals, the present longitudinal study...

Objective: Network typology studies have identified heterogeneous types of older adults' social networks. However, little is known about stability and change in social network types over time. We investigate transitions in social network types among older adults, aged 60 years and older, and factors associated with such transitions. Methods: We...

Background The importance of social network in mortality among older adults has been acknowledged. However, existing studies typically overlook the interplay among social network indicators, and seldom consider the change in social network over time. We take a person-centered approach to identify transitions between social network profiles, and exa...

Employability may play an important role in the job seeking behavior and well-being among unemployed youth. To date, the literature has tended to study the indicators of employability individually, without considering the intertwinement among them. The present research (N = 447 unemployed youth [16 to 24 years] in Hong Kong) addressed this gap. We...

Background Cerebrospinal fluid t-tau (CSF t-tau) is a measure of neurodegeneration in Alzheimer’s disease (AD) and has been increasingly demonstrated to be a non-specific biomarker within the AD continuum. Objective We sought to test whether t-tau influences the longitudinal effects of amyloid-β (Aβ) and phospho-tau (p-tau) on memory and executive...

Objectives: The association between family support exchange and personal mastery among older adults remains unclear. The present study addresses this gap. Methods: We utilized two waves of data from the Panel on Health and Ageing of Singaporean Elderly (N= 1398). Latent class analysis was conducted to identify distinct patterns of family support...

Background : The relation of changes in sleep duration with risk of cognitive impairment are inconclusive. This study evaluated the prospective relationships of changes in sleep duration with risk of cognitive impairment in Singapore Chinese. Methods : We used data from 16,948 Chinese men and women who were aged 45-74 years at baseline (1993-1998)...

Objectives: Little is known about composite patterns of productive engagement among older people. Related, the implication of these patterns for well-being remains unclear. The present study addresses these gaps. Methods: The analytical sample comprised 2037 community-dwelling Singaporeans aged 60 years and above. We included nine productive activi...

Background: In Singapore, English is predominantly used on prescription medication labels (PMLs). However, many older Singaporeans cannot read English, and among those who read English, their English health literacy (EHL) proficiency varies. It is thus pertinent to examine the link between EHL and medication use outcomes in this population. The pre...

Introduction: Few studies in Asia have examined the association among depressive symptoms, relationship satisfaction, sexual dysfunction and emotional expressiveness. Examining the role of emotional expressiveness in the context of depression and relationships is important as it can be a point for therapeutic intervention. Materials and methods:...

Prospective memory (PM) enables us to execute previously conceived intentions at a later time and is used when remembering to call a friend or submitting a proposal on time. Evidence that sleep benefits PM is presently mixed. Further, when a benefit is observed, it is unclear if this is achieved through improvements in strategic monitoring (maintai...

Wealth inequality is a prevalent social issue. The present study focuses on acceptance of wealth inequality, and considers personal income, perceived upward mobility, and future time perspective as its antecedents, and collective action intention as its outcome. With reference to the social identity literature and socioemotional selectivity theory,...

Scholars are divided as to whether sexting—an unprecedented sexual activity using digital media—is objectifying or sexually liberating. One notion is that sexting involves the representation of an individual’s sexuality in the presence of others and thus reinforces objectification. Another perspective contends that the self-portrayal of the body in...

Objective: The relationship between stiffness and quality of life (QoL) remains unclear. We therefore aimed to examine the role of pain and function in linking stiffness and QoL in patients with axSpA. Methods: We used cross-sectional data from a registry of axSpA patients in a tertiary referral centre to assess the links among stiffness, pain a...

This meta‐analysis investigates the direction and strength of the relationship between diversity in culturally diverse teams and team creativity/innovation. We distinguish the effects of two diversity levels (i.e., surface‐ versus deep‐level) in culturally diverse teams and examine the moderators suggested by the socio‐technical systems framework (...

Purpose Sleep disturbance is common in late life. While social interaction is a basic human concern, few studies have explored the linkage between interpersonal relationships and sleep disturbance. The present study examines the reciprocal associations between weak social networks outside the household and sleep disturbance in elderly, as well as t...

Consistent with an evolutionary perspective, memory may be enhanced when people are in precarious situations. Particularly, a survival processing effect (SPE) has been found whereby people have better memory for a list of items when the items are rated for their relevance in a grassland context that contains survival threats including predators, an...

Background Aging is accompanied by cognitive decline that is escalated in older adults reporting extreme sleep duration. Social relationships can influence health outcomes and thus may qualify the association between sleep duration and cognitive function. The present study examines the moderating effects of marital status, household size, and socia...

Aims We explored the direct and indirect impact of restrictions in daily living activities on the relationship between perceived visual symptoms associated with diabetic retinopathy (DR) and psychological functioning. Methods In this prospective, cross-sectional study, 514 tertiary patients with DR (mean age±SD, 60.4±12.6 years; 64% male) answered...

Study Objectives: To determine the effects of changes in nocturnal sleep and daytime nap durations on all-cause mortality among older adults. Methods: 2448 community-dwelling older Singaporeans (≥60 years) reported their nocturnal sleep and daytime nap durations at baseline (2009) and the 2-year follow-up. At each phase, they were grouped into the...

Background Durations of nocturnal sleep and daytime nap influence the well-being of older adults. It is thus essential to understand their determinants. However, much previous research did not assess sleep duration and nap duration individually, and longitudinal data is lacking. This study aimed at examining the impact of demographic, psychosocial,...

The emergence and popularity of new communication tools provide opportunities for new sexual behaviours, among which is sexting. Sexting refers to sending nude or sexually suggestive pictures of oneself to another person through digital media. Extending Walrave, Heirman, and Hallam’s work [2014. “Under Pressure to Sext? Applying the Theory of Plann...

Purpose of the study: To (a) assess the validity and reliability of the 9-item Positive Aspects of Caregiving (PAC) scale among a national sample of caregivers for older adults with functional limitations, (b) develop a shorter version (short-PAC [S-PAC] scale) and assess its psychometric properties, and (c) investigate both scales' measurement eq...

Sleep is important for optimal cognitive functioning across the lifespan. Among older adults (≥55 years), self-reported short and long sleep durations have been repeatedly, albeit inconsistently, reported to elevate the risk for poor cognitive function. This meta-analytic review quantitatively summarizes the risk for poorer cognitive function among...

To evaluate and extend climato-economic theory, the use of more micro units of analysis, such as cities and families, may open up new data sources. The consideration of environmental demands other than thermal climate may also broaden the range of useful data. Longitudinal designs can provide causal evidence, and so can experiments if the theory ca...

The current research examines how peripheral group members differ from prototypical group members in reacting to procedural discrimination (favoring self vs. favoring other procedures). Results of two experiments reveal that peripheral members react more negatively when the authority procedurally favors a prototypical member over them than when the...

The present research examined whether reactions to procedural discrimination (favoring self vs. favoring other procedures) are qualified by whether the authority is an ingroup or an outgroup member. We argue that because we tend to demonstrate ingroup bias in an intergroup context, we should react more positively when we are favored over an outgrou...

The present meta-analysis examined the tenure, age, and gender differences in the relationship between job insecurity and its job-related and health-related consequences. A total of 133 studies, providing 172 independent samples, were included in the analysis. Our results basically replicated Sverke et al.'s (2002) meta-analytic findings with an up...

This study was designed to examine the qualities of online friendships with different gender compositions that had been maintained for varying periods of time. A total of 167 Hong Kong Internet-users rated the qualities of their same-sex and cross-sex online friendships on measures such as intimacy, trust, self-disclosure, and relational satisfacti...

The present study was designed to compare offline and online friendship qualities at different stages of relationship development. The sample consisted of 162 Hong Kong Internet users. They were asked to think of two friends, one they knew through face-to-face interactions and one they knew through the Internet, and then describe the qualities of t...
