RESUMO

BACKGROUND: The COVID-19 pandemic has had situational impacts and induced various psychological responses among residents. The present study aims to analyze the network structure of psychological responses to the pandemic and their relationships with situational impact, resilience, and well-being through a network approach. METHODS: An online survey recruited 1122 residents (mean age = 32.5 years, 65.4 % female) in Hong Kong from October 2020 to October 2021. The participants completed the Mental Impact and Distress Scale: Psychological Response (MIDc-PR) and other validated measures. Gaussian graphical modeling was conducted in R to identify the central MIDc-PR symptoms and their bridge linkages with situational impact, resilience, and well-being. RESULTS: In the MIDc-PR network, the central symptoms were 'Routine' and 'Images' for Anticipation and 'Tense' and 'Lonely' for Modulation, with 12 bridge edges between the two clusters. In the combined network, the MIDc-PR nodes showed 12 bridge edges with situational impact, particularly in the health domain. 'Concerned', 'Sleep', and 'Lonely' showed negative linkages with resilience; 'Unmotivated' and 'Trapped' showed negative linkages with well-being. The network models showed good levels of stability and did not differ significantly in network structure and global strength across gender and age groups. LIMITATIONS: The cross-sectional study design only allowed undirected associations in the network and could not model the within-subject effects. CONCLUSIONS: The study findings contributed to the literature by elucidating the network structure of psychological responses to the pandemic. The central and bridge symptoms have clinical implications as potential targets for future interventions.

RESUMO

BACKGROUND: The present study aimed to examine the comorbidity among symptoms of internet gaming disorder (IGD), social withdrawal, and depression using the network perspective. METHODS: An online survey recruited 3430 young people in Hong Kong (mean age = 19.4 years, 80.5 % male) via gaming channels in 2019. The participants completed the 9-item IGD Scale, Hikikomori Questionnaire, and Patient Health Questionnaire-9. Network analysis was conducted using R to estimate the central symptoms of IGD and depression in individual networks and identified the bridge symptoms in combined network of IGD, social withdrawal, and depressive symptoms. RESULTS: All network models showed high stability. 'Withdrawal', 'Loss of control', and 'Tolerance' were the central IGD symptoms, while 'Depressed mood' and 'Self-blame/guilt' were the central depressive symptoms. The bridge symptoms were 'Gaming as escape or mood relief' from IGD cluster, 'Depressed mood' and 'Self-blame/guilt' from depression cluster, and 'Marked social isolation at home' and 'Significant distress due to social isolation' from social withdrawal cluster. The combined network showed no significant differences in network structure and global strength across gender and age groups. LIMITATIONS: The cross-sectional sample only indicated undirected associations between the symptoms in the three clusters and could not model the intra-individual variation. CONCLUSIONS: The present study provided the first results on the comorbidity among IGD, social withdrawal, and depression at a symptom level among Chinese young people via network analysis. The bridge symptoms highlight potential targets for interventions of comorbidity among the disorders.

RESUMO

OBJECTIVE: Female labor-force participation (FLFP) has been theorized as contributing to higher suicide rates, including among women. Evidence on this relationship, however, has been mixed. This study explored the association between FLFP and suicide in an understudied context, Taiwan, and across 40-years. METHODS: Annual national labor-participation rates for women ages 25-64, and female and male suicide-rates, for 1980-2020, were obtained from Taiwan's Department of Statistics. The associations between FLFP rates and sex/age-stratified suicide-rates, and between FLFP rates and male-to-female suicide-rates ratios were assessed via time-series regression-analyses, accounting for autoregressive effects. RESULTS: Higher FLFP rates were associated with lower female suicide-rates (ß = -0.06, 95% CI (Credibility Interval) = [-0.19, -0.01]) in the adjusted model. This association held in the age-stratified analyses. Associations for FLFP and lower male suicide-rates were observed in the ≥45 age-groups. FLFP rates were significantly and positively associated with widening male-to-female suicide-rates ratios in the adjusted model (ß = 0.24, 95% CI = [0.03, 0.59]). CONCLUSION: This study's findings suggest that FLFP protects women from suicide, and point to the potential value of FLFP as a way of preventing suicide. In Taiwan, employed women carry a double-load of paid and family unpaid care-work. Child care-work is still done by mothers, often with grandmothers' support. Therefore, this study's findings contribute to evidence that doing both paid work and unpaid family care-work has more benefits than costs, including in terms of suicide-protection. Men's disengagement from family care-work may contribute to their high suicide rates, despite their substantial labor-force participation.


Female labor-force participation (FLFP) has been theorized to increase suicide.Over time higher FLFP was associated with lower suicide, particularly in women.Higher FLFP was associated with widening male-to-female suicide-rate ratios.

RESUMO

BACKGROUND: Online sexual experiences (OSEs) are becoming increasingly common in young adults, but existing papers have reported only on specific types of OSEs and have not shown the heterogeneous nature of the repertoire of OSEs. The use patterns of OSEs remain unclear, and the relationships of OSEs with sexual risk behaviors and behavioral health outcomes have not been evaluated. OBJECTIVE: This study aimed to examine the latent heterogeneity of OSEs in young adults and the associations with sexual risk behaviors and behavioral health outcomes. METHODS: The 2021 Youth Sexuality Study of the Hong Kong Family Planning Association phone interviewed a random sample of 1205 young adults in Hong Kong in 2022 (male sex: 613/1205, 50.9%; mean age 23.0 years, SD 2.86 years) on lifetime OSEs, demographic and family characteristics, Patient Health Questionnaire-4 (PHQ-4) scores, sex-related factors (sexual orientation, sex knowledge, and sexual risk behaviors), and behavioral health outcomes (sexually transmitted infections [STIs], drug use, and suicidal ideation) in the past year. Sample heterogeneity of OSEs was analyzed via latent class analysis with substantive checking of the class profiles. Structural equation modeling was used to examine the direct and indirect associations between the OSE class and behavioral health outcomes via sexual risk behaviors and PHQ-4 scores. RESULTS: The data supported 3 latent classes of OSEs with measurement invariance by sex. In this study, 33.1% (398/1205), 56.0% (675/1205), and 10.9% (132/1205) of the sample were in the abstinent class (minimal OSEs), normative class (occasional OSEs), and active class (substantive OSEs), respectively. Male participants showed a lower prevalence of the abstinent class (131/613, 21.4% versus 263/592, 44.4%) and a higher prevalence of the active class (104/613, 17.0% versus 28/592, 4.7%) than female participants. The normative class showed significantly higher sex knowledge than the other 2 classes. The active class was associated with male sex, nonheterosexual status, higher sex desire and PHQ-4 scores, and more sexual risk behaviors than the other 2 classes. Compared with the nonactive (abstinent and normative) classes, the active class was indirectly associated with higher rates of STIs (absolute difference in percentage points [Δ]=4.8%; P=.03) and drug use (Δ=7.6%; P=.001) via sexual risk behaviors, and with higher rates of suicidal ideation (Δ=2.5%; P=.007) via PHQ-4 scores. CONCLUSIONS: This study provided the first results on the 3 (abstinent, normative, and active) latent classes of OSEs with distinct profiles in OSEs, demographic and family characteristics, PHQ-4 scores, sex-related factors, and behavioral health outcomes. The active class showed indirect associations with higher rates of STIs and drug use via sexual risk behaviors and higher rates of suicidal ideation via PHQ-4 scores than the other 2 classes. These results have implications for the formulation and evaluation of targeted interventions to help young adults.

RESUMO

The COVID-19 pandemic poses substantial risks to individuals' physical and mental health and prolonged psychological responses to the pandemic could lead to emotional exhaustion. The present study aimed to examine the mediating role of COVID-19 related mental impact and distress in the relationship among resilience, burnout, and well-being. The present study recruited 500 community adults (mean age = 38.8 years, SD = 13.9; 76% females) in Hong Kong via an online survey in autumn 2021. The participants completed the Mental Impact and Distress Scale: COVID-19 (MIDc) and validated measures on resilience, burnout, and well-being. Confirmatory factor analysis was conducted to evaluate the psychometric properties of the MIDc. Direct and indirect effects of resilience on burnout and well-being via MIDc were examined via structural equation modeling. Confirmatory factor analysis supported factorial validity for the three factors of MIDc (situational impact, anticipation, and modulation). Resilience showed negative effects on the MIDc (ß = -0.69, SE = 0.04, p < 0.01) and burnout (ß = 0.23, SE = 0.06, p < 0.01). Burnout was positively associated with MIDc (ß = 0.63, SE = 0.06, p < 0.01) and negatively associated with well-being (ß = -0.47, SE = 0.07, p < 0.01). Resilience showed a significant and positive indirect effect (αßγ = 0.203, 95% CI = 0.131 to 0.285) on well-being via MIDc and burnout. The results support a potential mediating role for MIDc as psychological responses in the relationship among resilience and burnout and well-being.

RESUMO

Background: COVID-19 quarantine has been associated with increased sleep problems and prolonged psychological responses to the pandemic could mediate this relationship. The present study attempted to examine the mediating role of COVID-19 mental impact and distress between quarantine and sleep disturbance. Methods: The present study recruited 438 adults (109 with quarantine experience) in Hong Kong via an online survey between August and October 2021. The respondents completed a self-report questionnaire on quarantine, Mental Impact and Distress Scale: COVID-19 (MIDc), and Pittsburgh Sleep Quality Index (PSQI). The MIDc was treated as a latent mediator and continuous PSQI factor and poor sleep quality (PSQI score > 5) were the study outcomes. We evaluated the direct and indirect effects of quarantine on sleep disturbance via MIDc using structural equation modeling. Analyses were adjusted for gender, age, education level, knowing confirmed COVID-19 cases, COVID-19 frontline work, and primary income source of the family. Results: More than half (62.8%) of the sample reported poor sleep quality. Quarantine was associated with significantly higher levels of MIDc and sleep disturbance (Cohen d = 0.23 - 0.43, p < 0.05). In the structural equation model, the MIDc mediated the relationship between quarantine and sleep disturbance (αß = 0.152, 95% CI = 0.071 to 0.235). Quarantine significantly increased the proportion of poor sleep quality by 10.7% (95% CI = 0.050 to 0.171) indirectly via MIDc. Conclusions: The results provide empirical support to the mediating role of the MIDc as psychological responses in the relationship between quarantine and sleep disturbance.

RESUMO

Background: Young adults in Hong Kong are subject to elevated psychological distress given the societal stressors such as civil unrest and COVID-19 pandemic and suicide is a leading cause of death among them. The present study aimed to evaluate the psychometric properties and measurement invariance of the 4-item Patient Health Questionnaire-4 (PHQ-4) as a brief measure of psychological distress and its associations with meaning in life and suicidal ideation (SI) in young adults. Materials and methods: A mobile survey recruited a large and random sample of 1,472 young adults (Mean age = 26.3 years, 51.8% males) in Hong Kong in 2021. The participants completed the PHQ-4 and Meaning in Life Questionnaire-short form (MLQ-SF) for presence of meaning in life (MIL), SI, COVID-19 impact, and exposure to suicide. Confirmatory factor analysis was conducted to examine the factorial validity, reliability, and measurement invariance of PHQ-4 and MLQ-SF across gender, age, and distress subgroups. Multigroup structural equation model evaluated and compared the direct and indirect effects of latent MIL factor on SI via latent PHQ-4 factor across distress groups. Results: Both MIL and PHQ-4 supported a 1-factor model with good composite reliability (Ω = 0.80-0.86) and strong factor loadings (λ = 0.65-0.88). Both factors showed scalar invariance across gender, age, and distress groups. MIL showed significant and negative indirect effects (αß = -0.196, 95% CI = -0.254 to -0.144) on SI via PHQ-4. PHQ-4 showed a stronger mediating role between MIL and SI in the distress group (Δ = -0.146, 95% CI = -0.252 to -0.049) than the non-distress group. Higher MIL predicted higher likelihoods of help-seeking (Odds ratios = 1.46, 95% CI = 1.14-1.88). Conclusion: The present results support adequate psychometric properties in terms of factorial validity, reliability, convergent validity, and measurement invariance for the PHQ-4 in young adults in Hong Kong. The PHQ-4 demonstrated a substantial mediating role in the relationship between meaning in life and SI in the distress group. These findings support clinical relevance for using the PHQ-4 as a brief and valid measure of psychological distress in the Chinese context.

RESUMO

OBJECTIVE: The current study aimed to examine the latent heterogeneity of gaming and social withdrawal behaviors in internet gamers and their associations with help-seeking behaviors. METHOD: The present study recruited 3430 young people (1874 adolescents and 1556 young adults) in Hong Kong in 2019. The participants completed the Internet Gaming Disorder (IGD) Scale, Hikikomori Questionnaire, and measures on gaming characteristics, depression, help-seeking, and suicidality. Factor mixture analysis was used to classify the participants into latent classes based on their latent factors of IGD and hikikomori in separate age groups. Latent class regressions examined the associations between help-seeking and suicidality. RESULTS: Both adolescents and young adults supported a 4-class, 2-factor model on gaming and social withdrawal behaviors. Over two-third of the sample were classified as healthy or low-risk gamers with low IGD factor means and low prevalence of hikikomori. Around one-fourth was moderate-risk gamers with elevated prevalence of hikikomori, higher IGD symptoms and psychological distress. A minority of the sample (3.8%-5.8%) belonged to high-risk gamers with the highest IGD symptoms and prevalence of hikikomori and heightened suicidal risks. Help-seeking in low-risk and moderate-risk gamers was positively associated with depressive symptoms and negatively associated with suicidal ideation. Perceived usefulness of help-seeking was significantly linked with lower likelihoods of suicidal ideation in the moderate-risk gamers and suicide attempt in the high-risk gamers. CONCLUSIONS: The present findings explicate the latent heterogeneity of gaming and social withdrawal behaviors and associated factors on help-seeking and suicidality among internet gamers in Hong Kong.

RESUMO

BACKGROUND: Public involvement is an essential element of effective suicide prevention. However, few studies have investigated laypeople's intentions and behaviors in supporting suicidal people, especially within Chinese contexts. This study was conducted among young adults in Hong Kong to identify categories of helping intentions toward suicidal people, and to understand whether, and why, youth transitioned over time between helping intention categories. METHODS: A total of 807 Hong Kong young adults (18-35 years) participated in this two-wave study across 2018 (W1) and 2019 (W2). Latent class analyses were conducted to identify categories of helping intentions toward suicidal people. A latent transition analysis was applied to explore the stability of the categories over time, and the factors that influenced stability. RESULTS: Three categories were identified in both waves: 1) dedicated helpers (W1: 28.38 %, W2: 28.50 %), 2) willing helpers (W1: 30.24 %, W2: 33.83 %), and 3) inconsistent helpers (W1: 41.39 %, W2: 37.67 %). 73.48 % of the young adults stayed in the same category across two years. Gender, and attitudes toward suicide victims were related to category membership and transitions between categories. LIMITATIONS: Measurement of helping intentions may not be thorough. Further studies are required to examine whether the findings can be generalized to the other population. CONCLUSIONS: Effective community engagement is essential for suicide prevention. Young adults in Hong Kong exhibited different helping intentions toward suicidal people, that were moderately stable over a two-year period. Understanding how and why young adults behave differently toward suicidal people is important when planning effective suicide prevention programs.

RESUMO

The present study examined the psychometric properties of the 12-item Stroke-Specific Quality of Life Scale (SSQOL-12) in 184 stroke survivors in Hong Kong. The participants completed a self-report questionnaire including the SSQOL-12, SF-12 health survey, and validating variables at baseline and 148 stroke survivors completed SSQOL-12 two months later. Confirmatory factor analysis investigated the construct validity, reliability, and measurement invariance of SSQOL-12 across two months. Concurrent, convergent, and divergent validity was examined with respect to SF-12, hope, self-esteem, functional disability, anxiety, and depression. The original 2-factor model did not reveal a superior fit over the 1-factor model and a modified 1-factor model provided an acceptable fit to the data in both waves. The SSQOL-12 factor displayed substantial factor loadings (λ = 0.40-0.87), good internal consistency (Ω = 0.88), temporal stability (r = 0.70), and scalar measurement invariance across time. Stroke-specific quality of life was significantly associated with higher levels of SF-12, hope, and self-esteem and lower levels of functional disability, anxiety, and depression. Most correlations remained significant after controlling for demographic covariates and SF-12. The present findings offered empirical support for the validity and reliability of the unidimensional structure for SSQOL-12 as a measure of stroke-specific quality of life among stroke survivors.

RESUMO

Objectives: Stroke survivors are prone to functional impairments and reduced quality of life (QoL). This study examined the mediating role of social support and hope in the relationships between functional impairment, emotional distress, and QoL. Methods: A total of 188 stroke survivors in Hong Kong completed assessments on functional impairment, social support, and hope at baseline, with follow-up measurements of emotional distress at 2 months and QoL at 8 months. Structural equation modeling with bootstrapping was used to analyze the direct and indirect effects of functional impairment on emotional distress and QoL via the mediating factors of social support and hope. Results: The partial cascading model provided an adequate fit to the data. Functional impairment had significant negative direct effects on hope and physical QoL and social support had significant positive direct effects on hope and physical QoL. Social support had a significant positive indirect effect on physical QoL via hope and perceived stress and on psychosocial QoL via hope and depression. Functional impairment and hope had a significant negative interaction effect on perceived stress. Conclusion: The findings support a mediating role for hope in the relationship between social support and QoL in stroke survivors. The protective effect of hope on perceived stress was stronger among patients with greater functional impairment.

RESUMO

Saliva collection and handling procedures for salivary C-reactive protein (CRP) can be challenging due to a lack of standardized protocols. This study compared two collection methods used to quantify salivary CRP. Twenty-two Chinese adults provided two unstimulated whole saliva samples using passive drool and cotton-based collection devices in two consecutive mornings at baseline and 1 month later. The effects of various factors on CRP levels were analyzed using linear mixed models. Salivary CRP levels were significantly affected by collection time and method, but not day or wave. The CRP peaked upon awakening and declined 45 min later. CRP levels were significantly higher in the passive drool than in the cotton-based method. The Bland-Altman plot revealed relative and proportional biases. The difference in the CRP levels between the methods decreased as the CRP levels increased. Results suggest that passive drool and cotton-based collection methods should not be used interchangeably for measuring low levels of salivary CRP.

RESUMO

Young residents in care homes experience psychological distress arising from their complex family backgrounds. Residential care workers face job demands and are prone to burnout due to the role stress of balancing enormous workloads with residents' emotional needs. This 2-year study examined the changes in role stress, burnout, and residents' behavioral problems, and their temporal relationships in a sample of 381 young residents and 76 workers from residential care homes in Hong Kong. The workers completed the Role Questionnaire and Copenhagen Burnout Inventory and evaluated the residents' behavioral problems using the Child Behavior Checklist every 3 months. Latent growth modeling was used to analyze the temporal changes, and multilevel regression analysis was used to evaluate the associations between role stress and residents' behavioral problems. The workers displayed stable trends in role stress and burnout with significant inter-individual variations in temporal changes. The residents' total behavioral problems displayed piecewise decreasing trajectories with significant declines over the first 9 months. Controlling for baseline levels, changes in role stress showed significant and positive associations with changes in work burnout and total behavioral problems over the first 9 months. The findings provide support for the temporal relationships among role stress, work burnout, and residents' behavioral problems in a residential care setting.

RESUMO

BACKGROUND: Salivary C-reactive protein (CRP) could be a viable biomarker of inflammation and has been associated with stress outcomes. The hypothalamic-pituitary-adrenal axis can modulate stress-related inflammation. This study aimed to evaluate the interaction effects of immune-endocrine markers on psychological outcomes. METHODS: The study participants were 52 healthy Chinese adults who collected 10 saliva samples over 2 consecutive days at baseline. The participants completed validated measures on anxiety, depression, positive affect, and sleep disturbance at baseline and 1 month later. The stability and diurnal patterns of salivary cortisol and CRP were investigated via paired t-tests and repeated-measures analyses of variance. Regression analysis was used to examine the longitudinal associations between immune-endocrine markers and their interactions (cortisol [Cort]: morning CRP [CRPmorn] and Cort:CRPeven) and psychological measures. RESULTS: Salivary cortisol and CRP displayed satisfactory stability over 2 consecutive days and diurnal patterns of abrupt and gradual decline during the day, respectively. Controlling for baseline psychological measures and confounding variables, Cortmorn and diurnal cortisol slope was significantly and negatively associated with anxiety symptoms and positive affect 1 month later, respectively. Cort:CRPeven and Cort:CRPmorn was significantly and positively associated with depressive symptoms and sleep disturbance 1 month later, respectively. CONCLUSION: These findings offer initial support for the prognostic utility of salivary cortisol and CRP and their balance as determinants of psychological health in healthy adults.

RESUMO

Depressed people are prone to sleep disturbance, which may in return perpetuate the depression. Both depression and sleep disturbance influence proinflammatory cytokines interleukin (IL) 6 and 1ß. Thus interventions for depression should consider the effect on sleep disturbance, and vice versa. Integrative Body-Mind-Spirit (IBMS) and Qigong interventions have been applied in a wide range of health and mental health conditions, including depression and sleep disturbance. This study aimed to evaluate the effect of these two mind-body therapies for persons with both depressive symptoms and sleep disturbance. A three-arm randomized controlled trial was conducted among 281 participants, who were randomly assigned to either IBMS, Qigong or wait list control group. Participants in IBMS and Qigong groups received eight weekly sessions of intervention. Outcome measures were plasma concentrations of IL-6 and IL-1ß, and a questionnaire containing Pittsburgh Sleep Quality Index, Center for Epidemiologic Studies Depression Scale, Somatic Symptom Inventory, Perceived Stress Scale and Body-Mind-Spirit Holistic Well-being Scale. Outcomes were assessed at baseline (T0), immediate post-intervention (T1) and at three-months post-intervention (T2). Besides intervention efficacy analysis, path analysis was performed to explore the relations among perceived stress, depression, sleep disturbance, and IL-6 and IL-1ß values. The study found both IBMS and Qigong reduced depression, sleep disturbance, painful and painless somatic symptoms, IL-6 and IL-1ß levels, and increased holistic well-being. The effect sizes of IBMS and Qigong, mostly in the medium magnitude range, were approximatively equivalent. Path analysis models revealed a predictive role of perceived stress in depression and sleep disturbance, a bidirectional relationship between depression and sleep disturbance, and significant influence of depression and sleep disturbance on IL-6 and IL-1ß. Compared with control, the findings support the efficacy of IBMS and Qigong interventions in relieving depression and sleep disturbance, and in reducing IL-6 and IL-1ß levels.

RESUMO

The Chinese Health Questionnaire (CHQ) is a 12-item assessment tool of psychological distress. The present study systematically evaluated the psychometric properties of the CHQ in a large sample of 1968 young people in Hong Kong. The participants completed the CHQ online in 2018 and 869 of them completed a follow-up survey on the CHQ, suicidal ideation, hikikomori, and help-seeking in 2019. Dimensionality of the CHQ was assessed via confirmatory factor analysis using the robust weighted least square estimator in 2018 and 2019. Measurement invariance was investigated across gender, age groups, and time between 2018 and 2019. Convergent validity of the CHQ factors were evaluated with respect to the mental health outcomes in the multiple indicators and multiple causes (MIMIC) approach. Confirmatory factor analyses shortened the CHQ into 10 items and revealed a superior fit for the bifactor model with a general factor and two specific factors on somatic and depressive symptoms in both 2018 and 2019. The general factor demonstrated substantial factor loadings (λ = 0.58-0.91), good reliability (ΩH = 0.85), and temporal stability (r = 0.62), and scalar measurement invariance across gender, age groups, and time. The general factor was significantly and positively associated with suicidal ideation, hikikomori, and help-seeking. The two specific factors displayed lower factor loadings, reliability, temporal stability, and weaker associations with the mental health outcomes. The present findings lend support to a valid and stable bifactor structure with a strong general factor for the CHQ-10 among young people in Hong Kong.

RESUMO

Suicide is a global public health concern. The Stigma of Suicide Scale-Short Form (SOSS-SF) is a brief measure on the stigma toward suicide. This study aimed to examine the psychometric properties of the SOSS-SF in a sample of 1,946 adolescents and early adults (M age = 23.3, 69% females) in Hong Kong. The participants completed the SOSS-SF, measures on suicidal ideation and perceived distress, and binary items on lifetime risk behaviors online. Exploratory structural equation modeling evaluated the factor structure and reliability of the SOSS-SF in split samples and its measurement invariance, convergent validity, and discriminant validity in the overall sample. Contrary to a poor fit for the three-factor structure in the original 16-item SOSS-SF, the four-factor model showed a good fit in the revised 12-item version in both subsamples. The four factors (Glorification, Isolation, Disgrace, and Selfishness) loaded significantly on three items each (λ = .52-.93) and had adequate reliability (ω = .78-.88). The SOSS-SF displayed scalar invariance across age group, gender, and suicidal ideation and significant associations with validating variables. These results demonstrate a valid and reliable four-factor structure for the SOSS-SF and support its use for assessment of multifaceted stigma toward suicide.

RESUMO

PURPOSE: Suicide in young adulthood is a vital public health concern. There have been few systematic studies that examined the prevalence and transition of suicidal ideation classes in young adults and the factors associated with the transition. METHODS: This two-wave survey recruited 1269 young adults (Mean age = 24.0 years, 70.1% males) in Hong Kong. The participants completed the Suicidal Ideation Attributes Scale, Chinese Health Questionnaire, and help-seeking behaviors in 2018 and 2019. Latent profile analysis was used to classify the participants into latent classes of suicidal ideation with substantive checking under the 3-step approach. Latent transition analysis with measurement invariance examined the transition among the latent classes from 2018 to 2019 and the associations with help-seeking behaviors and change in psychological distress. RESULTS: Three latent classes of suicidal ideation were identified and over two-thirds of the participants belonged to the Low-risk class with minimal suicidal ideation. The prevalence of the High-risk class dropped from 10.2 to 7.2%, while that of the Moderate-risk class remained stable from 2018 to 2019. Increases in psychological distress predicted higher probabilities to remain at or transit into more risky classes. Engagement in help-seeking behaviors showed differential transitions in suicidal ideation across time. CONCLUSION: The findings suggest three latent classes of suicidal ideation with distinct profiles among the young adults. Deterioration in psychological distress showed a temporal effect on worsening of suicidal ideation over a 1-year period. Future studies should elucidate the comparative effectiveness of help-seeking behaviors via online and offline channels.

RESUMO

BACKGROUND: The Urbanicity Scale was developed based on the China Health and Nutrition Survey (CHNS) to measure the urbanization index of communities according to 12 components. The present study was designed to systematically investigate the factorial validity, reliability, and longitudinal measurement invariance (LMI) of the Urbanicity Scale. METHODS: Six waves of CHNS data from 2000 to 2015 were adopted. The factor structure and reliability of the Urbanicity Scale for 301 communities were examined using Bayesian exploratory factor analysis. Metric and scalar LMIs were evaluated using both the conventional exact and a novel approximate LMI approach via Bayesian structural equation modeling across various timeframes. RESULTS: The findings verified the one-factor structure for the Urbanicity Scale, with adequate reliability. LMI was established for the Urbanicity Scale only over a shorter timeframe from 2006 to 2009 but not over a longer timeframe from 2000 to 2015. Partial LMI was found in the factor loadings and item intercepts for the Urbanicity Scale over the 2004 to 2011 period. CONCLUSION: Interpretation of the temporal change in urbanicity was supported only for a shorter (2006 to 2009) but not a longer timeframe (2000 to 2015). Adjustments addressing the partial non-invariance of the measurement parameters are needed for the analysis of temporal changes in urbanicity between 2004 and 2011.

RESUMO

BACKGROUND: Mindfulness has emerged as an important correlate of well-being in various clinical populations. The present study evaluated the psychometric properties of the 20-item short form of the Five Facet Mindfulness Questionnaire (FFMQ-SF) in the Chinese context. METHODS: The study sample was 127 Chinese colorectal cancer patients who completed the FFMQ-SF and validated physical and mental health measures. Factorial validity of the FFMQ-SF was assessed using Bayesian structural equation modeling (BSEM) via informative priors on cross-loadings and residual covariances. Linear regression analysis examined its convergent validity with the health measures on imputed datasets. RESULTS: The five-factor BSEM model with approximate zero cross-loadings and one residual covariance provided an adequate model fit (PPP = 0.07, RMSEA = 0.06, CFI = 0.95). Satisfactory reliability (ω = 0.77-0.85) was found in four of the five facets (except nonjudging). Acting with awareness predicted lower levels of perceived stress, negative affect, anxiety, depression, and illness symptoms (ß = - 0.37 to - 0.42) and better quality of life (ß = 0.29-0.32). Observing, nonjudging, and nonreacting did not show any significant associations (p > .05) with health measures. Acting with awareness was not significantly correlated (r < 0.15) with the other four facets. CONCLUSION: The present findings provide partial support for the psychometric properties of the FFMQ-SF in colorectal cancer patients. The nonjudging facet showed questionable validity and reliability in the present sample. Further studies with larger sample sizes are needed to elucidate the viability of FFMQ-SF as a measure of mindfulness facets in cancer patients.
