Rest-activity behavior clusters within individuals to form patterns are of significant importance to their intrinsic capacity (IC), yet they have rarely been studied. A total of 1253 community-dwelling older adults were recruited between July and December 2021 based on the baseline survey database of the Fujian Prospective Cohort Study on Aging. Latent profile analysis was used to identify profiles of participants based on rest-activity behaviors, whereas logistic regression analysis was carried out to investigate the relationship between profiles and IC. We identified three latent profiles including: (1) Profile 1-labeled \"Gorillas\": High physical activity (PA), moderate sedentary behaviors (SB), screen time (ST) and sleep (n = 154, 12%), (2) Profile 2-labeled as \"Zebras\": Moderate PA, low SB, ST and high sleep (n = 779, 62%), and (3) Profile 3-labeled as\"Koalas\": High SB, ST, low PA and sleep (n = 320, 26%). Logistic regression revealed a negative correlation between low IC and the \"Gorillas\" profile (β = - 0.945, P < 0.001) as well as the \"Zebras\" profile (β = - 0.693, P < 0.001) among community-dwelling older adults, with the \"Koalas\" profile showing the weakest IC compared to the other profiles. The demographic traits i.e., female, older age, living alone, and low educational level also correlated with low IC. Identifying trends of rest-activity behaviors may help in drawing focus on older adults at risk of decreasing IC, and develop personalized improvement plans for IC.

Shift work tolerance (SWT) refers to the ability to adapt to shift work without significant adverse consequences. The present study aimed to examine the individual differences in SWT and their predictors and outcomes. Latent profile analyses were conducted using cross-sectional data collected form 448 Chinese male sailors who experienced a prolonged (>30 d) non-24-h rotating shift schedule at sea. Depression, anxiety, sleep disturbance, fatigue, domestic disruption, job satisfaction, work engagement, digestive and cardiovascular symptoms were included as indicators of SWT. The results showed that there existed 2 latent profiles of SWT named as High SWT group and Low SWT group. High SWT group was characterized by low levels on all negative bio-psycho-social outcomes but high levels of work engagement and job satisfaction, while Low SWT group exhibited completely opposite characteristics compared to High SWT group. The level of hardiness could predict profile membership that those with higher level of hardiness were more likely to belong to High SWT group. However, there were no significant differences observed in job performance between two groups. In conclusion, hardiness can serve as a predictor of personnel selection for shift work and hardiness-based intervention programs should be encouraged among the shift workers.

This study examined variations in positive well-being as a function of paranormal belief and schizotypy. A sample of 2,362 United Kingdom-based respondents completed self-report measures assessing paranormal belief, schizotypy, positive well-being (meaning in life, satisfaction with life, and self-esteem), paranormal experience, and belief in conspiracies. The paranormal belief was most strongly related to the cognitive-perceptual factor of schizotypy. Both paranormal belief and the cognitive-perceptual factor were associated with reporting paranormal experiences and endorsement of conspiracist beliefs. Despite commonality, paranormal belief and schizotypy were differentially related to well-being. Paranormal belief correlated positively with meaning in life (presence and search) and satisfaction with life. Schizotypy correlated negatively with presence, satisfaction with life, and self-esteem and positively with search. Latent profile analysis identified four subgroups: Profile 1, low belief and schizotypy (49% of the sample); Profile 2, low belief and cognitive-perceptual, moderate interpersonal and disorganised (13.6%); Profile 3, high belief, moderate cognitive-perceptual and interpersonal, low disorganised (24.3%); and Profile 4, high belief and schizotypy (13.1%). Multivariate analysis of variance (MANOVA) found that low belief with mixed schizotypy was associated with lower presence, and low belief and schizotypy (vs. high) were related to higher presence. Paranormal belief and schizotypy were associated with greater search, higher scores on paranormal experiential factors, and endorsement of generic conspiracist beliefs. Finally, lower belief and schizotypy were concomitant with higher satisfaction with life and self-esteem. Overall, paranormal belief was related to positive well-being, whereas schizotypy was associated with lower positive wellbeing.

Despite the growing support for the multiple developmental pathways to phenotypic callous-unemotional (CU) traits (i.e., primary, and secondary CU variants), there remains limited research on childhood manifestations of CU variants in non-Western, community samples. Using a latent profile analysis with data sourced from the longitudinal, nationwide Korean sample (N = 1597, 48.7% girls), we discerned heterogeneous groups of children, based on externalizing problems, CU traits, and emotional reactivity level. The optimal five-profile solution identified distinct subgroups: low-risk, primary CU (characterized by low emotional reactivity and externalizing problem), reactive (low CU/moderate emotion reactivity and externalizing problem), and two secondary CU groups (i.e., secondary-high CU and secondary-moderate CU; both high in emotional reactivity and externalizing problems). The two secondary CU variants demonstrated differences from the primary CU variants, in that both are high in preschool externalizing problems (age 6) and school-age conduct problems (age 11). However, the secondary-moderate CU group displayed greater levels of anxiety at age 11 compared to secondary-high CU, indicating divergent developmental trajectories of secondary CU variants. These findings expand our understanding of CU variants among Korean preschoolers and highlight the role of emotional reactivity in distinguishing such subtypes and identifying their developmental outcomes across time.

BACKGROUND: Nurses\' moral courage (NMC) enhances care quality and patient safety. Nurses\' professional values promote ethical adherence, moral obligation fulfillment, and compliance to prevent ethical violations. It is necessary to explore the current status and influencing factors of moral courage from the perspective of professional values.
OBJECTIVE: To investigate the current situation of nurses\' moral courage, analyze the latent profiles of nurses\' moral courage, and explore the influencing factors from the perspective of professional values.
METHODS: A cross-sectional design was employed.
METHODS: Data were collected through convenient sampling at a tertiary hospital during May 2023 in Wuhan, Hubei province, China. A self-designed web-based questionnaire consisting of demographic characteristics, the Chinese Nurses\' Professional Values Scale-Revised Version (NPVS-R-CV) and the Nurses\' Moral Courage Scale (NMCS) were used for the cross-sectional survey. Latent profile analysis was conducted using the results of 3 explicit indexes of NMCS, and multivariate logistic regression was used to analyze the influencing factors of NMC.
METHODS: Research ethics approval (with the code of TJ- IRB 20220543) was obtained from Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology.
RESULTS: This study included 966 nurses, predominantly female and under 30 years old, with 91.10% holding a bachelor\'s degree. Latent profile analysis identified three moral courage profiles: low-level (31.5%), medium-level (47.2%), and high-level (21.3%). Multivariate logistic regression analysis showed significant positive correlations between professional values and moral courage, with head nurses being significantly more likely to exhibit high moral courage (OR = 3.586, p = 0.013).
CONCLUSIONS: The moral courage of nurses can be classified into 3 subgroups. Nurses\' professional values positively correlate with moral courage, with head nurses showing significantly higher levels of moral courage. Strengthening professional values through training can enhance ethical behavior in nursing, potentially improving patient care and safety.

OBJECTIVE: Adolescent behavior is closely linked to personality, a key predictor of physical activity. Due to inconsistent findings on how personality dimensions influence physical activity, focusing on combinations of personality traits is more valuable for theoretical and practical guidance. This study aims to examine potential categories of adolescent personality and their relationship with physical activity.
METHODS: Using data from the 2014-2015 China Education Panel Survey (CEPS), 9212 adolescents reported their \"Big Five\" personality and physical activity levels after excluding samples with missing core values. Latent profile analysis with Mplus 8.3 determined the optimal model by comparing model fits to categorize personality types. Bolck-Croon-Hagenaars (BHC) analysis was used to compared physical activity across personality profiles based on the resulting class differences and its significance.
RESULTS: Latent profile analysis identified five personality trait types among adolescents based on fit indices such as AIC, BIC, aBIC, and Entropy: Low-control conservative group (5.0 %), Balanced development group (45.1 %), Optimistic action group (40.4 %), Independent avoidant group (4.5 %), and Introverted vulnerable group 5.0 %). Significant differences in physical activity were found among these profiles (p < 0.001), with individuals in the Optimistic action group tending to be more physically active and those in the Independent avoidance group being less physically active.
CONCLUSIONS: Adolescent personality can be classified into five categories, and different combinations of personality traits can predict physical activity. The findings help identify adolescents who lack physical activity based on their personality profiles, allowing for the design of targeted psychological interventions to promote exercise motivation and foster healthy exercise habits. However, the study has limitations include a narrow age range and a single evaluation method. Future research could incorporate diverse evaluation methods and long-term tracking.

Few theoretical and empirical works have described impostor phenomenon (IP) and no study explored impostorism from a dark perspective. We adopted a person-centered approach to identify clusters of impostors based on scores on the IP, perfectionistic self-presentation and the Dark Triad using a sample of 306 university students (Mage = 22.82). The latent profile analysis suggested a 6-cluster solution, which was further compared in terms of psychopathology symptoms (i.e., burnout, generalized anxiety, and fear of failure) by means of (M)ANOVAs. Our results indicated that impostorism relies on a self-presentation strategy. Moreover, individuals scoring high on IP experienced enhanced levels of psychopathology symptoms. Looking at IP from a continuum perspective might improve our understanding about what makes someone suffer from impostorism.

UNASSIGNED: Proinflammatory and neuroendocrine mediators are implicated in disease aetiopathogenesis. Stress increases concentrations of immune-neuroendocrine biomarkers through a complex network of brain-body signalling pathways. Suboptimal sleep further modulates these processes by altering major effector systems that sensitise the brain to stress. Given the ubiquitous, impactful nature of material deprivation, we tested for a synergistic association of financial stress and suboptimal sleep with these molecular processes.
UNASSIGNED: With data drawn from the English Longitudinal Study of Ageing (ELSA), associations were tested on 4,940 participants (~66±9.4 years) across four-years (2008-2012). Through analytical triangulation, we tested whether financial stress (>60% insufficient resources) and suboptimal sleep (≤5/≥9 hours) were independently and interactively associated with immune-neuroendocrine profiles, derived from a latent profile analysis (LPA) of C-reactive protein, fibrinogen, white blood cell counts, hair cortisol, and insulin-like growth factor-1.
UNASSIGNED: A three-class LPA model offered the greatest parsimony. After adjustment for genetic predisposition, sociodemographics, lifestyle, and health, financial stress was associated with short-sleep cross-sectionally (RRR=1.45; 95%CI=1.18-1.79; p<0.001) and longitudinally (RRR=1.31; 95%CI=1.02-1.68; p=0.035), and it increased risk of belonging to the high-risk biomarker profile by 42% (95%CI=1.12-1.80; p=0.004). Suboptimal sleep was not related to future risk of high-risk profile membership, nor did it moderate financial stress-biomarker profile associations.
UNASSIGNED: Results advance psychoneuroimmunological knowledge by revealing how immune-neuroendocrine markers cluster in older cohorts and respond to financial stress over time. Financial stress associations with short-sleep are supported. The null role of suboptimal sleep, as exposure and mediator, in profile membership, provides valuable insight into the dynamic role of sleep in immune-neuroendocrine processes.

BACKGROUND: Social participation is an important index of rehabilitation and social reintegration in patients after total knee arthroplasty (TKA). However, most existing studies focus on improving patients\' functioning and activities, with only a few examining the social participation among patients after TKA. Therefore, the study aims to investigate the heterogeneity of social participation in patients three months after TKA and analyze subgroup influencing factors, to promote functional exercise and postoperative follow-up in specific patients.
METHODS: This cross-sectional study recruited 255 patients who underwent TKA in a Tertiary Hospital in Jinan City, China, from March to July 2022. Three months after having undergone TKA, participants\' data were collected using the Numeric Pain Rating Scale, the Chinese version of the Tampa Scale of Kinesiophobia, the 10-item Kessler Psychological Distress Scale, Hospital for Special Surgery Knee-rating Scale, and Impact on Participation and Autonomy Questionnaire. Latent profile analysis was used to identify categories of patients\' social participation. Multiple logistic regression analysis was used to analyze the influencing factors of the different subgroups.
RESULTS: Three months after TKA, the patients were divided into three subgroups: low social participation group (17.9%), moderate social participation group (40.8%), and high social participation group (41.3%). The vast majority of patients who underwent TKA exhibited moderate-to-high level of social participation. The multiple logistic regression analysis results showed that age, degree of pain, knee function, and kinesiophobia were the influencing factors of the potential profiles of social participation in patients three months after TKA (p < 0.05).
CONCLUSIONS: These results support a distinct categorical feature of social participation among patients three months after undergoing TKA. Medical staff need to provide targeted guidance according to the potential classification characteristics of social participation to improve the level of social participation and promote rehabilitation of patients.

OBJECTIVE: To identify profiles of coping in parents of children with cancer and their underlying factors and to examine which profile(s) are associated with illness adaptation.
METHODS: A cross-sectional study utilizing surveys among parents of children with cancer (n = 89).
METHODS: Questionnaires included socio-demographics, ways of coping, parenting stress, depression, post-traumatic symptoms, illness adjustment and quality of life. Parental coping profiles were identified via latent profile analysis. Logistic multinomial regression was used to identify predictors of coping profiles. Adaptation outcomes were compared across the coping profiles via multivariable analyses of variance with Bonferroni adjustments.
RESULTS: Five profiles were identified: The \'Strong Repertoire\' used coping strategies moderate to high degree, with a positive-active orientation; The \'Moderate-Activist\' used a similar pattern, rather more moderately; The \'Self-Regulator\' used self-content strategies; The \'Mild-Engager\' used active-engaging strategies; The \'Avoidant Coper\' used avoidant-passive strategies. Parental stress predicted coping profiles, so that parents experiencing greater stress utilized the \'Avoidant Coper\' to a greater degree. Group comparisons revealed that \'Avoidant-Copers\' had more depressive and post-traumatic symptoms, worse illness adjustment and lower quality of life.
CONCLUSIONS: Passive-avoidant mechanisms of coping may be maladaptive in terms of parental cancer adaptation and indicative of lower resilience.
CONCLUSIONS: Findings can direct clinicians to promote familial resilience by adapting policy and practice to meet familial needs.
UNASSIGNED: Not applicable.
