The bi-directional relationships between diversified leisure activity participation and cognitive function in older adults in China: separating between-person effects from within-person effects

ObjectiveTo examine the bi-directorial association between diversified leisure activity participation and cognitive function over a 7-year period.MethodsData analyzed was from the Chinese Longitudinal Healthy Longevity Survey (CLHLS), a large-scale longitudinal national study. The baseline survey was conducted in 2011 with follow-up every three years. We traced a total of 2718 participants over a period of 7 years. We used adjusted random intercept cross-lagged panel models (RI-CLPMs) to examine the bi-directorial associations between diversified leisure activity participation and cognitive function.ResultsWe observed bi-directorial associations between diversity of leisure activity and cognitive function across waves at the between-person and within-person levels. The adjusted random intercept cross-lagged panel models fitted the data appropriately, and the 3-year cross-lagged effects of prior diversified leisure activity participation on cognitive function (β = 0.058, p < 0.01) and cognitive function on subsequent diversified leisure activity participation (β = 0.047, p < 0.05) were significant. The results remained after adjusting the model for baseline sex, age, educational level, marital status and current residence, the number of chronic diseases, ADL, depressive symptoms, sleep quality, smoking, and drinking.ConclusionThis study suggests that a reciprocal causality relationship between diversified leisure activity participation and cognitive function, indicating a “positive circle” that further promotes cognition over time.

The dynamic interactive influence of community identity, being accepted by others, and life satisfaction among relocated residents for poverty alleviation in China

In China, the ultimate goal of the relocation for poverty alleviation (RPA) policy is to ensure that the relocated poor smoothly relocate, stably resettle, and become wealthier. With the completion of smooth relocation, the next crucial task is to guarantee that residents relocated for poverty alleviation (RRPA) maintain stability. Given that RRPA's life satisfaction affects their willingness and behavior to stabilize their placement. This study aims to explore whether being accepted by others and community identity are related to RRPA life satisfaction, and whether these three variables have a mutual impact over time. Based on the social identity and need to belong theories, a model of the interactive influence of being acceptance accepted by others, community identity, and life satisfaction was constructed. Using a random intercept cross-lagged panel model (RI-CLPM), 383 RRPA datasets were analyzed. The results showed that being accepted by others significantly predicted life satisfaction for RRPA. Being accepted by others and community identity, as well as community identity and life satisfaction, can predict each other on cross-lagged paths. This suggests that resorting to community identity as an intermediate variable, being accepted by others and life satisfaction may form a virtuous cycle over time.

Disentangling between‐ and within‐person variation in relationship science

AbstractObjectiveThis article provides an overview of the Cross‐Lagged Panel Model (CLPM), Random‐Intercept Cross‐Lagged Panel Model (RI‐CLPM), and Latent Curve Model with Structured Residuals (LCM‐SR), highlighting the major issues of the CLPM for relationship science, and discusses dyadic extensions of those three models.BackgroundUnderstanding interdependencies among people and constructs is a central interest in relationship science. Addressing such research questions requires complex designs ideally using data collected at multiple measurement occasions of multiple constructs from at least two persons (e.g., both partners of a couple). The Cross‐Lagged Panel Model (CLPM) has been widely used to analyze such data, however, particularly during the last decade, it has been pointed out that the CLPM confounds between‐ and within‐person variation. As a consequence, alternative models such as the Random‐Intercept Cross‐Lagged Panel Model (RI‐CLPM) and the Latent Curve Model with Structured Residuals (LCM‐SR) were proposed that aim to disentangle between‐ and within‐person variation and, hence, allow conclusions regarding within‐person dynamics.MethodAs an illustrative example, we apply dyadic extensions of the CLPM, RI‐CLPM, and LCM‐SR to investigate the dynamic interplay between depression and relationship satisfaction in a sample of 1699 mixed‐gender couples surveyed in the German Family Panel.ResultsWhile the CLPM indicated a reciprocal relationship between depression and satisfaction, the RI‐CLPM and LCM‐SR indicated a unidirectional association flowing from depression to satisfaction.ConclusionWe discuss how findings like this can foster theory‐building and, ultimately, strengthen relationship science.

Dissociation As a Mechanism of Risk for Interpersonal Victimization Among Adolescent Girls.

Childhood interpersonal violence exposure (IVE) is associated with repeated victimization in adolescence and adulthood. Research suggests dissociation, a psychological phenomenon characterized by alterations and disruptions to consciousness, memory, and perceptions of the environment, and out-of-body experiences, increases the risk of revictimization. Self-report data from a longitudinal study of 92 violence-exposed adolescent girls from a large, urban area were analyzed to assess whether dissociation predicts polyvictimization or exposure to multiple types of interpersonal violence across adolescence. Participants' mental and interpersonal health was assessed at four in-person laboratory visits scheduled across 3.5 years (i.e., T1-T4). IVE included direct or indirect victimization experienced at home, school, the neighborhood, or town, such as child maltreatment, domestic violence, peer victimization, dating aggression, and community violence. Polyvictimization was operationalized as a composite score of the different types of IVE endorsed by the participant or caregiver. A random-intercept cross-lagged panel model was used to test the bidirectional relationships between dissociation and polyvictimization longitudinally. Cross-lagged regressions were analyzed to determine whether dissociation and polyvictimization predicted subsequent dissociation symptoms and polyvictimization. Concurrent and previous dissociation significantly accounted for polyvictimization at T2, T3, and T4. Polyvictimization did not significantly predict future dissociation symptoms. The results from this study provide support for dissociation's unique contribution to polyvictimization among violence-exposed girls, making it an important target for clinical assessment and treatment.

Prospective Relations between Life Stress, Emotional Clarity, and Suicidal Ideation in an Adolescent Clinical Sample

ABSTRACT Objective Although life stress has been linked to adolescent suicidal ideation, most past research has been cross-sectional, and potential processes characterizing this relation remain unclear. One possibility may be a lack of emotional clarity. Informed by stress generation, the current study examined prospective relations between episodic life stress, lack of emotional clarity, and suicidal ideation in an adolescent clinical sample. Methods The sample consisted of 180 youths (M age = 14.89; SD = 1.35; 71.7% female; 78.9% White; 43.0% sexual minority) recruited from a psychiatric inpatient facility. Suicidal ideation severity was assessed at baseline and 18-month follow-up. Lack of emotional clarity and life stress were assessed at baseline, as well as 6-, and 12-month follow-ups. Two random-intercepts cross-lagged panel models were created to estimate within-person relations for variables of interest. Results At the within-person level, lack of emotional clarity at baseline predicted greater 6-month impact of interpersonal dependent stressors (b = 0.29, p = .012, 95% CI [0.07, 0.52]), which subsequently predicted a greater 12-month lack of emotional clarity (b = 0.41, p = .005, 95% CI [0.12, 0.70]). Next, a 12-month lack of emotional clarity but not interpersonal dependent stress, predicted greater 18-month suicidal ideation (b = 0.81, p = .006, 95% CI [0.23, 1.30]; R 2 = .24, p < .001). No significant relations were found for the lack of emotional clarity and independent stress. Conclusions Results support the stress generation hypothesis and suggest that future research should be conducted evaluating whether bolstering youth’s understanding of their emotional experiences may reduce subsequent suicidal ideation.

Longitudinal Associations Between Depression, Suicidal Ideation, and Lack of Certainty in Control among Adolescents: Disaggregation of Within-Person and Between-Person Effects

PurposeDepression and suicidal ideation (SI) are common in adolescents. However, the relation between the two is unclear. According to the cognitive model of suicidal behavior and learned helplessness theory, lack of certainty in control (LCC), referring to individuals' deficiency in predictability, certainty, and control of life, may be an important factor linking the two. Thus, the current study aimed to investigate the temporal relation between depression and SI in adolescents and to assess the mediating role of LCC in this relation. MethodsA three-wave survey was carried out at intervals of 1 and 1.5 years among 516 adolescents at several middle schools in Sichuan Province, China. The random-intercept cross-lagged panel model was used to examine the temporal relations between depression, SI, and LCC among adolescents, which can effectively distinguish between-person and within-person differences. ResultsThe results revealed that depression, SI, and LCC had positive intercorrelations at the between-person level. At the within-person level, early depression predicted subsequent depression and SI via LCC among adolescents. Additionally, early LCC promoted later SI through depression. DiscussionThese findings highlight the mediating role of LCC, clarify the temporal relation between depression and SI, and provide theoretical support for interventions to address depression and suicide.

Bidirectional relationship between chronic pain and depressive symptoms in middle-aged and older adults

ObjectiveTo assess the bidirectional association between chronic pain and depressive symptoms among middle-aged and older adults from two prospective cohort studies. MethodsWe used prospective data (12y of follow-up) from the English Longitudinal Study of Ageing (n = 9149, 5018 women, 65.0 ± 10.2y) and the Health and Retirement Study (n = 16,883, 9810 women, 66.9 ± 10.3y), including data from seven waves of each cohort between 2006 and 2018/2019. Depressive symptoms were assessed using the Centre of Epidemiological Studies Depression scale, while chronic pain was estimated using questions about the frequency of being troubled with pain. We used random-intercept cross-lagged panel models to assess the bidirectional association between pain and depressive symptoms, adjusting for confounders. ResultsThere was a cross-lagged effect of chronic pain with depressive symptoms (ELSA: β: 0.038; 95%CI: 0.011–0.066. Standardized coefficient (B): 0.021. SHARE: β: 0.044; 95%CI: 0.023–0.065. B: 0.023–0.024) as well as depressive symptoms with pain (ELSA: β: 0.010; 95%CI: 0.002–0.018. B: 0.017–0.019. SHARE: 0.011; 95%CI: 0.005–0.017. B: 0.020–0.021). Moreover, there were auto-regressive effects of both chronic pain (ELSA: β: 0.149; 95%CI: 0.128–0.171. SHARE: β: 0.129; 95%CI: 0.112–0.145) and depressive symptoms (ELSA: β: 0.149; 95%CI: 0.130–0.168. SHARE: β: 0.169; 95%CI: 0.154–0.184). ConclusionWe identified a modest bidirectional association between depressive symptoms and chronic pain, using two large prospective ageing cohorts.

Disaggregating within- and between-person associations to test the aversive transmission of alcohol use in late adolescence through adulthood.

The theory of aversive transmission posits that children of parents who have an alcohol use disorder (AUD) may abstain or limit their own alcohol use because they believe themselves to be at risk of developing problems with alcohol. The present study examined relationships among parental AUD, perceived parental AUD, perceived risk for AUD, addiction avoidance reasons for limiting alcohol use, and alcohol use using a random intercept cross-lagged panel model. Participants (N = 805; 48% female; 28% Latinx) were from a longitudinal study investigating intergenerational transmission of AUD. Parental AUD, perceived parental AUD, perceived risk for AUD, addiction avoidance reasons for limiting alcohol use, and alcohol use (quantity, frequency, and frequency of heavy drinking) were measured every 5 years from late adolescence (Mage = 20) to adulthood (Mage = 32). Random intercept cross-lagged panel models tested whether there were stable between-person relations or time-varying within-person relations among these variables. At the between-person level, perceived parental AUD predicted greater addiction avoidance reasons for limiting alcohol use and greater perceived risk. Those with greater addiction avoidance reasons for limiting alcohol use were less likely to use any alcohol and drank less frequently. Parental AUD was associated with higher levels of alcohol use as well as perceived risk. No consistent cross-lagged paths were found at the within-person level. Study findings were at the between-person level rather than the within-person level. Future work on aversive transmission is needed to better understand this subgroup of children of parents with AUD.

Relationships with teachers and sense of belonging in school: Inter- and intra-individual variations according to adolescent immigrant background

BackgroundSocial well-being arises from the fulfillment of the basic need for relatedness. In school, it largely hinges on teacher-student relationships (TSR) and sense of school belonging (SSB), two important levers for educational success, and especially for immigrant-background youths. AimsThis study aims to disentangle the stable and time-specific associations between the two dimensions of social well-being and test if these associations vary according to student immigrant status. SampleA cohort of 1070 students (51% female) from first- (22%), second- (29%), and third-plus generations (49%) attending 10 schools located in low-socioeconomic neighbourhoods was followed across three time points (grade 7, grade 9, grade 11). MethodMain objectives were tested using random-intercept cross-lagged panel models (RI-CLPM) using Mplus. RI-CLPM disaggregates observed scores into a time-invariant interindividual (stable) and intraindividual (time-specific) components. ResultsTeacher-student closeness was not associated with SSB at the interindividual level. However, autoregressive, cross-sectional, and longitudinally links were found at the intraindividual level for all students. Teacher-student conflict was associated with lower SSB at the interindividual level. These dimensions were also linked at the intraindividual level for third-plus-generation students only, while time-variant autoregressive associations for SSB were stronger for immigrant students. ConclusionsThe links between close TSR and SSB are cross-sectional and time-specific for all students. Conflictual TSR and SSB also showed time-specific and longitudinal associations for nonimmigrants only. For immigrants, we observed stronger time-specific carryover effects in terms of SSB. This research calls for yearly intervention efforts promoting social well-being among immigrants and nonimmigrants attending low-SES secondary schools.

Adolescent responses to paternal verbal aggression: Assessing spillover and compensatory processes using random intercept cross-lagged panel models.

Prior research suggests several pathways through which verbal aggression manifests across adolescent relationship contexts, including spillover (continuity of aggression across different relationships) and compensation (offsetting an aggressive relationship with less aggression in other relationships). These pathways vary across timescales in ways that between-person analytic approaches are unlikely to adequately capture. The current study used random intercept cross-lagged panel modeling (RI-CLPM) to examine adolescents' spillover and compensatory responses to paternal verbal aggression. Participants were 184 adolescents (53.2% female) from a United States community sample participating in a longitudinal study. Annually from ages 13-17, participants reported on their experiences of verbal aggression in their paternal and maternal relationships and participated in observed interactions with a close peer that were coded for aggressive behavior. Spillover was observed from father-adolescent to mother-adolescent and adolescent-peer contexts in analyses at the between-person level, likely capturing long-term, cumulative effects of paternal aggression. Conversely, compensation was observed in analyses at the within-person level, likely capturing medium-term (i.e., year-to-year) adaptations to paternal aggression: Adolescents who experienced more aggression from their father than expected at a specific time point were less likely to both perpetrate and experience aggression in maternal and peer relationships the following year. Several findings differed across teen gender, with compensation more likely to occur in males than females. These findings highlight the multiple pathways by which father-adolescent aggression may be linked to behavior in other relationships in the medium- and long-term. They also support the value of RI-CLPM in decomposing these effects.

Shared and distinct effect mediators in exposure-based and traditional cognitive behavior therapy for fibromyalgia: Secondary analysis of a randomized controlled trial

Fibromyalgia is a chronic pain condition associated with substantial suffering and societal costs. Traditional cognitive behavior therapy (T-CBT) is the most evaluated psychological treatment, but exposure therapy (Exp-CBT) has shown promise with a pronounced focus on the reduction of pain-related avoidance behaviors. In a recent randomized controlled trial (N = 274), we found that Exp-CBT was not superior to T-CBT (d = −0.10) in reducing overall fibromyalgia severity. This study investigated pain-related avoidance behaviors, pain catastrophizing, hypervigilance, pacing, overdoing and physical activity as potential mediators of the treatment effect. Mediation analyses were based on parallel process growth models fitted on 11 weekly measurement points, and week-by-week time-lagged effects were tested using random intercepts cross-lagged panel models. Results indicated that a reduction in avoidance behaviors, pain catastrophizing, and hypervigilance were significant mediators of change in both treatments. An increase in pacing and a reduction in overdoing were significant mediators in T-CBT only. Physical activity was not a mediator. In the time-lagged analyses, an unequivocal effect on subsequent fibromyalgia severity was seen of avoidance and catastrophizing in Exp-CBT, and of overdoing in T-CBT. Exposure-based and traditional CBT for fibromyalgia appear to share common treatment mediators, namely pain-related avoidance behavior, catastrophizing and hypervigilance.

Day-to-day associations between mindfulness and perceived stress: insights from random intercept cross-lagged panel modeling.

Mindfulness is frequently seen as a protective factor of stress, but self-report measures of mindfulness may overlap with other related constructs, such as mental health, and could thus not only be a predictor, but also an outcome of stress. This study thus aimed to examine the longitudinal bidirectional associations between the use and perceived helpfulness of the four mindfulness facets Observe, Describe, Nonjudge, and Nonreact with daily perceived stress. Participants from a large (N = 1,276) mixed student and community group sample filled out a brief daily diary over the time span of 7 days. Bidirectional cross-lagged effects were investigated using the random-intercept cross-lagged panel model, an extension of the traditional cross-lagged panel model that allows to differentiate between stable between-unit differences and time-varying within-unit dynamics. In addition, we controlled for several baseline and sociodemographic confounders. At the within-subject level, the use of Actaware was associated with higher perceived stress on the next day (β = 0.03, p = 0.029). The use (β = -0.04, p = 0.025) and perceived helpfulness (β = -0.05, p = 0.014) of Nonreact were associated with lower perceived stress on the next day. In turn, perceived stress was associated with lower perceived helpfulness of Describe (β = -0.04, p = 0.037) and Nonreact (β = -0.03, p = 0.038) on the next day. In addition, there were several residual correlations between mindfulness facets and perceived stress within days. At the between-subject level, there was a positive association between the random intercept of Describe and daily stress (r = 0.15, p = 0.003). In addition, while baseline perceived stress was negatively associated with the random intercepts of the mindfulness facets, two baseline components of mindfulness were not associated with the random intercept of perceived stress. On the currently investigated time scale, our results challenge prior results and assumptions regarding mindfulness as a buffering and protective factor against daily stress. With the exception of Nonreact, mindfulness was either positively associated with perceived stress, or in turn perceived stress appeared to interfere with the ability to stay mindful in daily life.

New parents’ sleep, movement, health, and well-being across the postpartum period

ABSTRACT Objective The aim of this study was to examine changes and the bi-directional relationship in sleep and movement, and health and well-being among new parents and differences by sex. Methods This secondary data analysis included both conditions from a randomized control trial to improve new parents’physical activity [PA] and recruited couples. Parents (n = 181, 117 couples represented 31.5 ± 4.4 years, 51.3% women, 83.3% White) completed questionnaires on regular overnight sleep duration, PA, mental health (perceived stress), physical health (physical quality of life [PQoL]), and well-being (life satisfaction) at 2-, 4-, 6-, and 8-month postpartum. Random-intercept cross-lagged panel models were stratified by sex to examine changes in sleep and PA with health and well-being across time. Results Sleep and stress were interrelated at different times for fathers (2 months), and mothers (8 months). Sleep and PQoL improved across time, with mothers reporting less sleep than fathers at 4 and 6 months. PQoL at 4 months was related to MVPA at 6-months. Life satisfaction and PA at 2 months was related to PA at 4 months. Conclusion Mothers and fathers experienced different sleep and stress trajectories. Mental health improved postpartum with early connections to PA. Supporting the 24-hour movement behavior cycle and mental health across the parenthood transition may benefit couples.

Emotions or cognitions first? Longitudinal relations between executive functions and emotion regulation in childhood.

Executive functions and emotion regulation develop from early childhood to adolescence and are predictive of important psychosocial outcomes. However, despite the correlation between the two regulatory capacities, whether they are prospectively related in school-aged children remains unknown, and the direction of effects is uncertain. In this study, a sample drawn from two birth cohorts in Norway was biennially examined between the ages of 6 and 14 (n = 852, 50.1% girls, 93% Norwegian). Parents completed the Emotion Regulation Checklist, and teachers completed the Behavior Rating Inventory of Executive Function. A random intercept cross-lagged panel model revealed that improved emotion regulation predicted increased executive functioning to the same extent throughout development, whereas enhanced executive functioning was unrelated to future changes in emotion regulation.

Vulnerable self-disclosure co-develops in adolescent friendships: Developmental foundations of emotional intimacy

This study examines the development of vulnerable self-disclosure in supportive interactions from ages 13 to 29. A diverse community sample ( N = 184; 85 boys 99 girls; 58% white, 29% Black, 13% other identity groups) participated in annual observed interactions with close friends and romantic partners. Participants were observed as they sought and provided support to their best friends each year from age 13 to 18, and as they sought support from their romantic partners from age 19 to 29. Random intercept cross-lagged panel models were used to parse markers of within-individual change in vulnerable self-disclosure observed annually across ages 13 to 18. A follow-up regression model also investigated cascading associations from vulnerable self-disclosure in adolescent friendships to vulnerable self-disclosure in adult romantic relationships. When adolescents sought support, they demonstrated greater-than-expected increases in self-disclosure each year when their best friends demonstrated relatively high self-disclosure. For girls in this sample, when providing support, they demonstrated greater-than-expected decreases in self-disclosure each year when their best friends demonstrated relatively high self-disclosure. Adolescents whose friends disclosed highly to them also tended to express more vulnerability with romantic partners in adulthood. Post-hoc analyses investigate the role of friendship stability and gender as potential moderators of self-disclosure development. The best friendship, a key source of emotional support, serves as a foundational context for learning appropriate use of vulnerable self-disclosure when seeking and providing emotional support, which persists across time and relationships.

Unpacking the Myth in the Associations Between Self-control and Gaming Disorder in Children and Adolescents: A Comparison Between Traditional and Random Intercept Cross-lagged Panel Model Analyses

AbstractInternet gaming is becoming increasingly popular; however, children and adolescents are highly vulnerable to gaming disorder due to the underdevelopment of cognitive control. Longitudinal research providing empirical evidence confirming the stability and direction of the association between self-control and gaming disorder is scarce. This study is aimed at clarifying whether prospective relationships exist between self-control and gaming disorder in children and adolescents or whether they are associated due to common causes. We examined the temporal dynamics of the associations between self-control and gaming disorder symptom severity using a traditional cross-lagged panel model (CLPM; aggregating between- and within-person variance) and a random intercept CLPM (RI-CLPM; disaggregating between- and within-person effects) with three-annual wave data from a large cohort of primary and secondary students (N = 1359, mean age 12.67 (SD 1.40), 834 (61.7%) girls). The traditional CLPM indicated a unidirectional negative relationship from self-control to later gaming disorder (B with 95% confidence interval [CI] =  − 0.12 [− 0.19, − 0.040]), whereas the RI-CLPM analysis revealed no prospective relationship between self-control and gaming disorder (95% CIs of Bs all contain 0), indicating that self-control was neither the cause nor the result of gaming disorder in children and adolescents. Our study revealed that the nature of the relationship between self-control and gaming disorder tends to be correlational but not causal. The potential common underlying factors for future research are discussed.

Anxiety, Sleep Problems, and Vigorous Physical Activity: Bidirectional Associations from Early Adolescence to Early Adulthood in Swedish Adolescents.

Anxiety symptoms and sleep problems typically emerge during adolescence and are frequently intertwined. However, there is a dearth of knowledge concerning their reciprocal influence and whether physical activity might play a protective role in this relationship. The present study aims at filling this gap exploring also the moderating role of sex. 915 13-year-old Swedish adolescents (56% girls) answered a survey conducted four times: at ages 13 (T1), 16 (T2), 19 (T3), and 22 (T4). A random intercept cross-lagged panel model was used. At within-levels, sleep problems and anxiety symptoms had a bidirectional positive association in middle adolescence. Vigorous physical activity and anxiety symptoms showed a reciprocal negative association from middle adolescence. Vigorous physical activity and sleep problems were reciprocally associated only in late adolescence. Associations were the same for girls and boys. This study demonstrated that the relations between anxiety symptoms, sleep problems, and vigorous physical activity cannot be understood without adopting a developmental perspective and that middle adolescence is a crucial period to plan interventions to reduce anxiety symptoms and sleep problems.

Associations between interconnectedness, compassion, and participation in collective action for people with mental illness: A random-intercept cross-lagged panel modeling approach.

The present study aims to prospectively investigate the relationships between interconnectedness, compassion, and participation in private and public forms of collective action for people with mental illness. Public form refers to collective action at the macrolevel such as large-scale protests and demonstrations going on in the communities. Private form refers to collective action happening at the microlevel that targets promoting awareness of social inequalities and positive changes among personal social circles, such as calling out microaggressions or correcting others' stigmatizing language. Eligible responses from 501 participants were collected at baseline, with 345 and 318 participants retained at 6-month and 12-month follow-up assessments, respectively. Random-intercept cross-lagged panel models were conducted to investigate the mediating role of compassion in the relationships between interconnectedness and participation in private and public forms of collective action. Interconnectedness was consistently associated with a higher frequency of participation in private form, but not public form, of collective action at subsequent time points. Contrary to the hypothesis, results showed the nonsignificant mediating effect of compassion between interconnectedness and participation in both forms of collective action. The present study highlights the potential of interconnectedness in promoting a private form of collective action for the rights of people with mental illness.

The dynamic and reciprocal relationship between perceived everyday discrimination and cognitive function in later life

Objectives This study, based on socioemotional selectivity theory and cognitive theory, investigates the dynamic and reciprocal relationship between perceived discrimination and cognitive function in later life. Methods Data were drawn from four waves of the Health and Retirement Study (HRS 2006, 2010, 2014, and 2018). A total of 4,125 people who were 51 and older were included. Cognitive function was measured by the telephone interview for cognitive status (TICS-27). Perceived discrimination was measured using scores of the perceived everyday discrimination scale. Random intercept cross-lagged panel model (RI-CLPM) was utilized. The model was adjusted for a range of covariates. Subgroup analysis by ethnoracial groups was conducted. Results Cross-sectionally, while lower cognitive function was associated with higher perceived discrimination, this relationship was unidirectional. Longitudinally, higher perceived discrimination predicted lower cognitive function in later waves only among non-Hispanic White individuals. Conclusion Results suggested that a decline in cognitive function may precede and contribute to the worsening of perceived discrimination, which may result in further decline in cognitive function. Lifetime experience of discrimination was discussed as a possible source of the racial/ethnic variations in the relationship. Further study is needed to examine whether this relationship holds among people with cognitive impairment and dementia.

The Vicious Cycle between Loneliness and Problematic Smartphone Use among Adolescents: A Random Intercept Cross-Lagged Panel Model.

Despite extensive research on the psychological impacts of digital technology, the nuanced dynamics between adolescent loneliness and problematic smartphone use, particularly across different educational levels and genders, remain underexplored. This study aims to fill this gap by employing a Random Intercept Cross-Lagged Panel Model to dissect the bidirectional relationship between loneliness and problematic smartphone use among adolescents, with a focus on the moderating roles of educational levels and gender. Engaging 3132 students from various educational institutions in China, the research conducted a three-wave longitudinal analysis across 2022-2023. The final number of participants included 1120 adolescents (53.5% female; age in 2022: M = 14.57 years, SD = 1.57). Results reveal that loneliness significantly predicts problematic smartphone use, but not vice versa, highlighting a unidirectional influence. The study uncovers crucial differences across educational levels and gender, emphasizing the stronger effect of loneliness on problematic smartphone use among junior high students and female adolescents. These findings underscore the complexity of adolescent loneliness and its relationship with digital behavior, suggesting a need for tailored interventions considering both gender and developmental stages.
