Applying behavioral economics to understand changes in alcohol outcomes during the transition to adulthood: Longitudinal relations and differences by sex and race.

Population drinking trends show clear developmental periodicity, with steep increases in harmful alcohol use from ages 18 to 22 followed by a gradual decline across the 20s, albeit with persistent problematic use in a subgroup of individuals. Cross-sectional studies implicate behavioral economic indicators of alcohol overvaluation (high alcohol demand) and lack of alternative substance-free reinforcers (high proportionate alcohol-related reinforcement) as potential predictors of change during this developmental window, but longitudinal evidence is sparse. Using a sample of emerging adults (N = 497, Mage = 22.61 years, 62% female, 48.69% White, 40.44% Black), this study examined prospective, bidirectional relations between both past-week heavy drinking days (HDD) and alcohol problems and proportionate alcohol-related reinforcement (reinforcement ratio), alcohol demand intensity (consumption at zero price), alcohol demand Omax (maximum expenditure), and change in demand elasticity (rate of change in consumption across escalating price) over five assessments (every 4 months) using random intercept cross-lagged panel models. Alcohol problems and HDD decreased across assessments. Significant between-person effects indicated that each behavioral economic variable was associated with increased drinking risk. Change in reinforcement ratio was positively associated with decreases in alcohol problems. Multigroup invariance modeling revealed distinct risk pathways in that change in demand intensity and Omax predicted change in alcohol problems for male participants and change in intensity predicted change in alcohol problems for non-White participants. The study provides consistent support for proportionate alcohol-related reinforcement and mixed support for demand as within-person predictors of reductions in drinking.

Can cross-lagged panel modeling be relied on to establish cross-lagged effects? The case of contemporaneous and reciprocal effects.

This article considers identification, estimation, and model fit issues for models with contemporaneous and reciprocal effects. It explores how well the models work in practice using Monte Carlo studies as well as real-data examples. Furthermore, by using models that allow contemporaneous and reciprocal effects, the paper raises a fundamental question about current practice for cross-lagged panel modeling using models such as cross-lagged panel model (CLPM) or random intercept cross-lagged panel model (RI-CLPM): Can cross-lagged panel modeling be relied on to establish cross-lagged effects? The article concludes that the answer is no, a finding that has important ramifications for current practice. It is suggested that analysts should use additional models to probe the temporalities of the CLPM and RI-CLPM effects to see if these could be considered contemporaneous rather than lagged.

Bidirectional longitudinal associations between parental self-efficacy and child rule-breaking behaviours: A random-intercept cross-lagged panel study.

Parental self-efficacy (PSE) is a pivotal determinant of change in children's adjustment. However, not only has previous research shown that PSE plays a protective role for children's rule-breaking (RB) behaviours (i.e., parent-driven process), but RB also can reduce parents' PSE over-time (i.e., child-driven process). This study examined the bidirectional longitudinal associations between PSE and RB behaviours by disentangling maternal from paternal influences and between- from within-person effects. In the present seven-wave longitudinal study involving 200 Italian children (T1: Mage = 9.80, SD = 0.65; 50.5% girls), their mothers (N = 200) and fathers (N = 190), two random-intercept cross-lagged panel models (one for mothers and one for fathers) were used to explore whether: (a) stable parts of PSE and RB were related to each other, (b) higher levels of PSE were associated with lower levels of RB at a given time point, and (c) higher levels of PSE at a given time point were associated with future lower levels of RB. Results provided evidence both for a parent- and a child-driven process between mothers' PSE and children's RB behaviours. However, these results were not replicated for fathers. Implications are discussed.

The bidirectional longitudinal associations between fear of negative evaluation and suicidal ideation among Chinese adolescents: The mediating role of interpersonal needs factors

Based on previous theories and studies, fear of negative evaluation (FNE) may be a key predictor of suicidal ideation in adolescents. However, few studies examined the longitudinal relationships between FNE and suicidal ideation. This study aimed to explore the bidirectional longitudinal relationships between FNE and suicidal ideation. Meanwhile, based on the Interpersonal Theory of Suicide, this study would examine the longitudinal mediating role of interpersonal needs factors (thwarted belongingness and perceived burdensomeness) on the relationship between FNE and suicidal ideation.A sample of 515 adolescents (Mage = 12.309, SD = 0.807; 49.3 % girls) completed questionnaires on 4 waves, 6 months apart. The Random Intercept Cross-Lagged Panel Models (RI-CLPMs) were utilized to estimate the associations among study variables. The results showed that: (1) there was a significant bidirectional longitudinal relationship between FNE and suicidal ideation; (2) thwarted belongingness and perceived burdensomeness independently and serially mediated the relationship between FNE and suicidal ideation.This study contributed to understanding the complex relationship between FNE and suicidal ideation, emphasizing the critical roles of thwarted belongingness and perceived burdensomeness. The findings underscore the bidirectional nature of these associations and provide insights into the potential pathways involved in the development of suicidal ideation among adolescents.

Longitudinal Change in Appearance-Related Social Media Consciousness and Depressive Symptoms: A Within-Person Analysis during Early-to-Middle Adolescence.

Online appearance preoccupation may put adolescents at risk of developing mental health challenges, perhaps especially during early-to-middle adolescence. A random intercept cross-lagged panel model assessed within-person associations between appearance-related social media consciousness and depressive symptoms over three time-points with three months between waves. The sample (n = 1594) included U.S. adolescents aged 11-15 (Mage = 13; 47% girls, 46% boys, 7% another gender; 37% Latine, 33% White, 18% Black, 7% Asian). Within-person increases in appearance-related social media consciousness were associated with subsequent increases in depressive symptoms, but not vice versa. There was no evidence of gender differences and results were robust to controlling for both time on social media and offline self-objectification. Thus, online appearance concerns precede mental health challenges during early and middle adolescence.

Family cumulative risk, life satisfaction, and anxiety and depression in adolescents: A developmental cascades model.

Family cumulative risk (FCR) is predominantly regarded as an antecedent for adolescent mental health, as the prevailing perspective continues to emphasize the influential role of parents, despite recognizing the child's influence. To identify the interplay between family adversity (FCR, process-related FCR, and sociodemographic-related FCR), life satisfaction (LS), and anxiety and depression (AD), this study examined the cascade effects among these constructs. Participants (N = 707; 52.9% male; grades 10 and 11) from four high schools in Wuhan, China, were recruited to participate, and they completed the measures in October 2018, April 2019, and November 2019. Family sociodemographic risk (e.g., single parenthood) and family process risk (e.g., low family cohesion) were simulated in the models for FCR, sociodemographic-related FCR, and process-related FCR. The random intercept cross-lagged panel models (RI-CLPMs) revealed a lagged effect from LS to FCR; lagged effects from LS and AD to process-related FCR at the within-person level; and significant associations between LS, AD, and family adversity at the between-person level. The lagged effects provide evidence for the influential child perspective and suggest that FCR and family process risk are sensitive to adolescent well-being and psychopathological symptoms. School mental health prevention and intervention programs that take a complete mental health approach to enhance children's well-being and alleviate symptoms would help prevent increases in family risk.

Longitudinal effects of sexual minority stigma on depressive symptoms among young men who have sex with men: Distinguish between and within person effects.

Young men who have sex with men (YMSM) may experience high levels of sexual minority stigma (SMS) and depressive symptoms (DS) over the world and in China. However, there is a lack of studies investigating the longitudinal effects of SMS on DS of YMSM, especially focusing on YMSM and separating the between-person and within-person effects. This study aimed to fill the said gaps. Study data were derived from a prospective cohort of 349 YMSM from central China (Wuhan, Changsha, Nanchang), the baseline survey was started in 2017 with one follow-up visit every year. SMS and DS were measured three times using valid and reliable instruments. The cross-lagged panel model (CLPM) and the random intercept CLPM (RI-CLPM) were used to examine the between-person and within-person concurrent and lagged effects, respectively. Findings of CLPM revealed bidirectional associations between SMS and DS over time. RI-CLPM suggested that at the between-person level, SMS was significantly associated with DS, echoing the results of CLPM. However, this reciprocal relationship has not been found at the within-person level. The associations between SMS and DS among YMSM at the population level is more significant than that at the individual level. We suggest that interventions should be against the adverse effects of cultural marginalization and systemic change the social concepts to reduce the amount of SMS in society.

Within-person bidirectional associations between maternal cortisol reactivity and harsh parenting across infancy and toddlerhood.

To understand transactional associations between mothers' biological stress responsivity and parenting behaviors, we examined bidirectional effects between maternal cortisol reactivity to observing their children during distress-eliciting paradigms and harsh parenting across infancy and toddlerhood using longitudinal data from the Family Life Project (N = 1,292, 41.5% African American). Children completed a series of distress-eliciting laboratory paradigms when they were 7, 15, and 24 months old, and mothers observed their children during the paradigms. Maternal cortisol reactivity was computed as a residualized change score from baseline to 20 min postparadigm, controlling for the time of day the saliva sample was collected. Harsh parenting was measured using five items from the Home Observation Measurement of the Environment inventory. A random-intercept cross-lagged panel model revealed that increases in maternal cortisol reactivity at 15 months predicted subsequent increases in harsh parenting at 24 months. Similarly, increases in harsh parenting at 15 months predicted increases in maternal cortisol reactivity at 24 months. Findings indicate that increased cortisol reactivity to children's distress in early toddlerhood may indicate a risk for harsh parenting in late toddlerhood and that increases in harsh parenting can also negatively impact mothers' stress physiology over time.

Circular causality in daily coparenting processes among first-time parents.

Although coparenting has been widely studied, little is known about the daily processes of coparenting between mothers and fathers in early parenthood. Based on family systems theory and the ecological model of coparenting, we investigated new parents' day-to-day within-family processes of cooperative and tensioned coparenting. Mothers and fathers from 144 Finnish first-time couples completed daily mobile diaries for 7 consecutive days when their firstborn was 4-6 months old. The random-intercept cross-lagged panel model showed three types of within-family processes in daily coparenting, which we named continuity, spread, and shift. Continuity in cooperative coparenting occurred when a parent's previous-day cooperative coparenting positively predicted his or her own cooperative coparenting experiences the next day. We also found that coparenting experiences spread from one spouse to another: A parent's cooperative coparenting on the previous day negatively predicted his or her spouse's experiences of tensioned coparenting the following day. Finally, daily coparenting experiences also shifted from day to day: One parent's experience of tensioned coparenting the previous day positively predicted that parent's cooperative coparenting experiences the next day. No gender differences were found. These findings emphasize that the two daily coparenting dimensions seem to operate partly differently in daily life, as cooperative coparenting was slightly more often a cause and consequence in the observed processes than tensioned coparenting. Therefore, it seems that interventions should focus on enhancing cooperative coparenting. Moreover, the new concepts of continuity, spread, and shift are proposed as better descriptions of the three daily processes. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Examining dynamic developmental trends: the interrelationship between age-friendly environments and healthy aging in the Chinese population—evidence from China Health and Retirement Longitudinal Study, 2011–2018

BackgroundThe objective of this research is to investigate the dynamic developmental trends between Age-Friendly Environments (AFE) and healthy aging in the Chinese population.MethodsThis study focused on a sample of 11,770 participants from the CHARLS and utilized the ATHLOS Healthy Aging Index to assess the level of healthy aging among the Chinese population. Linear mixed model (LMM) was used to explore the relationship between AFE and healthy aging. Furthermore, a cross-lagged panel model (CLPM) and a random-intercept cross-lagged panel model (RI-CLPM) were used to examine the dynamic developmental trends of healthy aging, taking into account both Between-Person effects and Within-Person effects.ResultsThe results from LMM showed a positive correlation between AFE and healthy aging (β = 0.087, p < 0.001). There was a positive interaction between the geographic distribution and AFE (central region * AFE: β = 0.031, p = 0.038; eastern region * AFE: β = 0.048, p = 0.003). In CLPM and RI-CLPM, the positive effect of healthy aging on AFE is a type of Between-Person effects (β ranges from 0.147 to 0.159, p < 0.001), while the positive effect of AFE on healthy aging is Within-Person effects (β ranges from 0.021 to 0.024, p = 0.004).ConclusionFirstly, individuals with high levels of healthy aging are more inclined to actively participate in the development of appropriate AFE compared to those with low levels of healthy aging. Furthermore, by encouraging and guiding individuals to engage in activities that contribute to building appropriate AFE, can elevate their AFE levels beyond the previous average level, thereby improving their future healthy aging levels. Lastly, addressing vulnerable groups by reducing disparities and meeting their health needs effectively is crucial for fostering healthy aging in these populations.

Longitudinal and Reciprocal Effects in the Association Between School Bullying and Homicidal Ideation During Early Adolescence.

Several cross-sectional studies indicated a positive association between school bullying and homicidal ideation during early adolescence. However, few longitudinal studies investigated this association. This study examined whether a bi-directional relationship exists within the longitudinal association between bullying victimization or bullying perpetration and homicidal ideation among early adolescents using a Random Intercept Cross-Lagged Panel Model. A total of 1611 early adolescents (39.5% girls; Mage = 12.50 years, SD = 0.50) were recruited from the Chinese Early Adolescents Cohort study. Data on bullying victimization, bullying perpetration, and homicidal ideation collected during three time points (September 2019, September 2020, and September 2021) were used. Bullying victimization showed a significant positive association with homicidal ideation at the between-person level. Bullying victimization and bullying perpetration had a bi-directional relationship with homicidal ideation at the within-person level. Additionally, this study considered the impact of biological sex-based differences and bullying types on adolescents' homicidal ideation. Based on these findings, school bullying might exhibit unique reciprocal associations with homicidal ideation.

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.

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 potential confounders. ResultsThere was a cross-lagged effect of chronic pain on 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 on 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.

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.

Bidirectional relationship between intraindividual changes in behavioral activation and intraindividual changes in postpartum depressive symptoms: A random intercept cross-lagged panel model.

According to Lewisohn's model of depression, decreases in behavioral activation (BA) occurring after facing a vital stressor may increase the risk of depression. Transition to parenthood is a potentially stressful life event that increases the risks of postpartum depression. We aimed to (a) describe the changes in BA and depressive symptomatology between the prepartum period, 1 month, 3 months, and 6 months postpartum and (b) evaluate the bidirectionality of the relationship between intraindividual changes in BA and intraindividual changes in depressive symptoms longitudinally. Chilean pregnant women (N = 503) completed a battery of questionnaires when they were between 32 and 37 weeks of gestation and 1, 3, and 6 months after delivery. A repeated measures analysis of variance showed that BA significantly decreased from prepartum to 1 month postpartum. A random intercept cross-lagged panel model supported the bidirectional inverse relationship between intraindividual changes in BA and intraindividual changes in depressive symptoms. The effect sizes of these associations were large (βs ranging from -.141 to -.243) according to Orth et al. (2022)'s recommendations for cross-lagged effect benchmarks. This relationship showed robustness when multigroup random intercept cross-lagged panel models were conducted to adjust for several covariates (i.e., marital status, the type of health insurance, type of delivery, primiparous vs. multiparous participants, and pregnancy or delivery complication or newborn health problem). Nonetheless, reporting a previous history of major depression moderated this relationship so that intraindividual decreases in BA more likely led to intraindividual increases in depressive symptoms in people with a history of depression than in people without such a history. We discuss implications for behavioral models of depression. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Longitudinal associations between subjective cognitive impairment, pain and depressive symptoms in home-dwelling older adults: Modelling within-person effects.

Cognitive impairment, pain and depressive symptoms are common and interrelated factors in older adults. However, the directionality and specificity of their association remains unclarified. This study explored whether these factors prospectively increase reciprocal risk and examined the longitudinal association between these factors and quality of life (QoL). This study used longitudinal data from The Older Persons and Informal Caregivers Survey Minimal Data Set (TOPICS-MDS; the Netherlands). Older adults self-reported cognitive impairment, pain, depressive symptoms and QoL at baseline and after 6 and 12months of follow-up. The Random Intercept Cross-Lagged Panel Model was used to assess the prospective association between the three factors, while a multilevel linear regression analysis in a two-level random intercept model was used to examine the longitudinal associations between the three factors and QoL at the within-person level. The data of 11,582 home-dwelling older adults with or without subjective cognitive impairment were analysed. At the within-person level, pain at 6months was associated with subsequent depressive symptoms (β=0.04, p=0.024). The reverse association from depression to pain, and longitudinal associations between pain and subjective cognitive impairment and between depressive symptoms and subjective cognitive impairment were non-significant. Pain, depressive symptoms and subjective cognitive impairment showed a significant association with poor QoL 6months later. A directional relationship was observed from pain to depressive symptoms. Pain reduction holds a potential benefit in the prevention of depressive symptoms, ultimately optimising the QoL of older adults.

The longitudinal relationship between life events and loneliness in adolescence: A twin study.

The aim of the study was to examine associations between life events and self-assessed loneliness in adolescence. We used data from a Norwegian population-based twin sample including seven birth cohorts (N = 2,879, 56% females). The participants completed self-report questionnaires three times throughout adolescence, with 2 years in between (i.e., 12-18 years old at Wave 1). By using a random intercept cross-lagged panel model (RI-CLPM), we were able to separate stable influences in the measured constructs from the within-person changes at each measurement occasion. In addition, using data from twins allowed us to examine to what degree the associations between life events and loneliness were genetic and/or environmental in nature. The results showed moderate stability of both loneliness and aggregation scores of life events throughout adolescence. The life events were assigned to clusters based on their independence (i.e., events considered dependent or independent on a person's behavior) and desirability (i.e., positive or negative). The time-stable between-person variance in all three measures, loneliness and person-dependent positive and negative life events, could almost exclusively be accounted for by genetic factors. However, as expected, also shared environmental factors influenced person-independent life events. The associations between time-stable between-person variance in loneliness and life events were small, and nearly exclusively due to shared genetic influences. Furthermore, life events do not seem to predict changes in loneliness or vice versa. In conclusion, the self-reported levels of loneliness throughout adolescence seems to be independent of life events. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
