[PMID: 38852860 DOI: 10.1016/j.jad.2024.06.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 05/29/2024] [Accepted: 06/03/2024] [Indexed: 06/11/2024]
Abstract
BACKGROUND Loneliness and posttraumatic stress (PTS) are common in adolescence. However, there has been little longitudinal research on their association. To address this deficit, this study examined the longitudinal association between these phenomena in a sample of U.S. school students while also exploring if gender was important in this context. METHODS Data were analysed from 2807 adolescents (52.1 % female; age at baseline 11-16 years (M = 12.79)) who were followed over a one-year period. Information was obtained on loneliness in year 1 using a single-item question, while PTS was assessed with the self-report Child Post-Traumatic Stress - Reaction Index (CPTS-RI). A full path analysis was performed to assess the across time associations. RESULTS Almost one-third of the students reported some degree of loneliness while most students had 'mild' PTS. In the path analysis, when controlling for baseline PTS and other covariates, loneliness in year 1 was significantly associated with PTS in year 2 (β = 0.06, 95%CI: 0.02, 0.09). Similarly, PTS in year 1 was significantly associated with loneliness in year 2 (β = 0.19, 95%CI: 0.15, 0.23). An interaction analysis further showed that loneliness was higher in girls with PTS than in their male counterparts. LIMITATIONS The use of a single-item measure to assess loneliness that used the word 'lonely' may have resulted in underreporting. CONCLUSION Loneliness and PTS are bidirectionally associated in adolescence. Efforts to reduce loneliness in adolescence may help in combatting PTS, while clinicians should intervene to address loneliness if detected in adolescents with PTS.

Abstract
BACKGROUND Subclinical psychotic-like experiences (PLEs) are common among general population adolescents but have been found to correlate with various problems in well-being. Due to limited sample sizes these effects have not been well differentiated by sex and age. METHODS Using a nationally representative survey of almost 160,000 adolescents, we studied endorsement and correlates of PLEs by sex among middle adolescence pupils (ages 14-16) and late adolescence students (ages 16-20). PLEs were investigated with three questionnaire items: auditory and visual hallucinatory experiences and suspicious thought content, using a frequency response scale. RESULTS Weekly PLEs were reported by 14 % of the adolescents, more often in females (17 %) than males (11 %) and in the younger age group (17 %) compared to the older adolescents (10 %). A latent PLE factor represented the three assessed PLEs with good fit. Factor scores were highest for the younger females and lowest for the older males. The PLE factor correlated with two latent factors of other well-being, namely living environment ("adversity", loading most heavily on parental mental abuse; r = 0.63), and concurrent mental health ("distress", loading most heavily on depressive symptoms; r = 0.50). Adversity was associated especially strongly with PLEs in 14-16-year-old males. CONCLUSIONS This cross-sectional study reaching the whole 14-20 age group in schools in Finland offers data on the meaning and relevance of PLEs as general markers of vulnerability. Many adolescents experience PLEs recurrently and these experiences are associated with a wide variety of burden in the adolescent's everyday life.

Results from the experience sampling method study. Compr Psychiatry 2024; 135:152521.

Abstract
BACKGROUND Several studies have shown that social isolation and loneliness are associated with the occurrence of psychotic experiences. However, dynamics of these phenomena in people with subclinical experiences, commonly referred to as psychotic-like experiences (PLEs), remains largely unknown. Therefore, in this study we performed a temporal network analysis to model dynamic predictions between social isolation, loneliness, negative affect, social stress, and PLEs. METHODS A total of 77 drug-naïve individuals with PLEs from a transdiagnostic sample were enrolled. Data were obtained using the experience sampling method (ESM). The ESM questionnaires were delivered during 7 consecutive days (6 assessments per day). Therefore, 3234 data entries were analyzed. RESULTS Social isolation predicted next-moment emergence of PLEs through the effects on loneliness and negative affect. Also, PLEs appeared to predict next-moment loneliness, but not social isolation, through the effects on negative affect. Social stress did not predict any variables in the network. However, it was predicted by previous-moment PLEs and social isolation. Negative affect had the highest in-strength and out-strength centrality. CONCLUSIONS Findings from the present study indicate that social isolation might predict the emergence of PLEs through the effects of momentary loneliness and negative affect. Also, loneliness might be bidirectionally associated with PLEs. Interventions targeting negative affect and social isolation might be beneficial in people with PLEs.

Abstract
BACKGROUND Understanding the etiology of psychosis is essential to the development of preventive interventions. The COVID-19 pandemic provides a rare natural experiment that can expand our understanding of the role of social factors in the trajectories and etiology of psychosis across adolescence, particularly in Tokyo where the prevalence of actual COVID-19 infection remained low. We hypothesized that the likelihood of self-reporting psychotic experiences (PEs) would increase following the onset of the COVID-19 pandemic. METHODS The Tokyo Teen Cohort (TTC) is a prospective cohort study of adolescents in the general population of the Tokyo metropolitan area, followed from age 10 to 16 years. We used multi-level linear regression models to test the associations between the phase of the COVID-19 pandemic and self-reported PEs. RESULTS Among 1935 adolescents included in the analysis, a rapid increase in PEs occurred at the onset of the COVID-19 pandemic, following approximately 6 years of steady decline across prior waves. This association was more pronounced for boys compared to girls. This increase became more pronounced as the pandemic moved into later phases, defined based on contemporaneous sociopolitical changes in Tokyo (i.e. changes to school closure, social distancing guidelines, and the state of emergency status). CONCLUSIONS The steady decline in PEs across adolescence was halted and reversed concurrent with the COVID-19 pandemic onset, despite very low rates of COVID-19 infection. This implicates COVID-19 related socioenvironmental factors as contributory etiological factors in the development of PEs in this adolescent cohort.

Abstract
Although cross-sectional studies have suggested that discrimination has a negative impact on the mental health of patients with COVID-19, no cohort studies with longitudinal data have established a causal relationship. Therefore, this study aimed to investigate the association between COVID-19-related discrimination and subsequent psychotic experiences in individuals who had contracted the disease. Secondary outcomes were PTSD symptoms, psychological distress, and suicidal ideation. We utilized inverse probability weighting and marginal structural models with robust standard errors to analyze the association, accounting for confounders and loss to follow-up. In a sensitivity analysis, we evaluated the robustness of the estimates to potential unmeasured confounding by analyzing E-values. Of 7760 participants who had contracted COVID-19, 5971 were included after excluding those with missing sociodemographic data. Of these, 1736 (29.1 %) reported experiencing COVID-19-related discrimination. Of the 2559 participants who completed the study, 253 (9.9 %) reported having at least one psychotic experience. Participants who reported experiencing any COVID-19-related discrimination showed a higher risk of subsequent psychotic experiences compared with participants without such discrimination (risk difference 6.6 %, 95 % CI 4.0 %-9.9 %; risk ratio 1.82, 95 % CI 1.42-2.47). A negative impact was also found in suicidal ideation, PTSD symptoms, and psychological distress. E-values demonstrated the robustness of some of the observed associations to unmeasured confounding. The study found that COVID-19-related discrimination was associated with subsequent psychotic experiences and other mental health outcomes in individuals who had contracted the disease. A study focusing on prevention strategies, such as an anti-discrimination campaign, is warranted.

Abstract
BACKGROUND The relationship between psychosis and disordered eating remains a challenging area of research to which little interest was paid. Using longitudinal data, we aimed to explore the hypothesis that the pathways from psychotic experiences (PEs) to disordered eating (DE) and body-mass index (BMI) are mediated by body-image disturbances. METHODS A prospective longitudinal study was performed. High-school students (N = 510, 61.2% females, mean age of 16.05 ± 1.01 years) were asked to complete three scheduled assessments (Baseline, 6 months, and 12 months). RESULTS Two body image components, that is, Overweight Preoccupation and Body Area Satisfaction, mediated the prospective association between baseline PEs and DE 12 months later. Direct effects were significant. After accounting for indirect effects through more severe body image concerns at 6 months, higher baseline PEs were significantly associated with greater DE at 12 months. Baseline PEs and 6-month body image explained a significant proportion of variance in 12-month DE. However, we did not find evidence of a direct prospective association between PEs and BMI. CONCLUSION This study is the first to assess the mediating role of body image between PEs and DE. Findings offer promising new avenues for early intervention to help mitigate the effects of PEs on DE in adolescents.

Abstract
AIM Bi-directional associations between loneliness and psychotic experiences (PEs) have been reported, but the mechanisms underlying these associations are unknown. This study aims to explore associations between daily reports of loneliness and PEs, and test differences in this association across young adult individuals at different levels of risk for psychosis. METHODS We analysed 90-day diary data on loneliness and PEs from N = 96 participants (mean age 24.7, range 18-35, 77% female) divided into 4 subgroups, each indexing increased levels of risk for psychosis according to the clinical staging model: 'psychometric' (n = 25), 'low' (n = 27), 'mild' (n = 24), and 'ultra-high'(n = 20) risk. Multilevel vector autoregressive models examined within-day (contemporaneous) and between-day (temporal) associations between loneliness and PEs for the total sample. Next, these associations were compared across subgroups. RESULTS Loneliness and PEs were significantly associated contemporaneously (partial correlation B = 0.14) but not temporally. Subgroup membership moderated both contemporaneous and temporal associations. The contemporaneous association between loneliness and PEs was stronger in the low-risk subgroup compared to the mild-risk (B = -0.35, p < .01) and ultra-high-risk (B = -0.36, p < .01) subgroups. The temporal association between loneliness on the previous day and PEs on the current day was stronger in mild-risk subgroup compared to the ultra-high-risk subgroup (B = -0.03, p = .03). After adjusting for multiple testing, only the contemporaneous-but not the temporal-associations remained statistically significant. CONCLUSIONS Loneliness is associated with PEs in individuals at risk for psychosis, particularly in those with low to mild symptoms. Our findings tentatively suggest that especially individuals with low expressions of PEs may be more sensitive to social context, but future studies are needed to replicate and further unravel the potentially stage-specific interplay between social context and PEs.

Abstract
BACKGROUND Little information is available on the association between gender nonconformity during adolescence and subsequent mental health. While the distress related to gender nonconformity may be socially produced rather than attributed to individual-level factors, further research is needed to better understand the role of psychosocial factors in this context. METHOD We analyzed data from the Tokyo Teen Cohort, obtained through random sampling of adolescents born between 2002 and 2004. We used inverse probability weighting to examine the association of gender nonconformity at ages 12 and 14 as a time-varying variable with subsequent mental health at age 16, while accounting for time-fixed and time-varying confounders. Furthermore, we used a weighting approach to investigate the mediating role of modifiable psychosocial factors in this association, addressing exposure-mediator and mediator-mediator interactions. RESULTS A total of 3171 participants were analyzed. Persistent gender nonconforming behavior at ages 12 and 14 was associated with subsequent depression (β = 2.02, 95% confidence interval [CI] 0.85 to 3.19) and psychotic experiences (β = 0.33, 95% CI 0.14 to 0.52) at age 16. The results remained robust in sensitivity analyses. Approximately 30% of the association between gender nonconformity and depression was consistently mediated by a set of psychosocial factors, namely loneliness, bullying victimization, and relationships with mother, father, and friends. CONCLUSIONS Persistent gender nonconformity during adolescence is associated with subsequent mental health. Psychosocial factors play a vital mediating role in this association, highlighting the essential need for social intervention and change to reduce stigmatization and ameliorate mental health challenges.

Abstract
PURPOSE This paper aims to investigate associations between early childhood and current indicators of socioeconomic inequality and the onset (incident), persistence and progression (increase in severity) of psychotic experiences (PEs) in a longitudinal follow-up of a community-based population. METHODS Households in the metropolitan area of Izmir, Turkey were contacted in a multistage clustered probability sampling frame, at baseline (T1, n = 4011) and at 6-year follow-up (T2, n = 2185). Both at baseline and follow-up, PEs were assessed using Composite International Diagnostic Interview 2.1. The associations between baseline socioeconomic features and follow-up PEs were analysed using logistic regression models. Indicators of social inequality included income, educational level, current socioeconomic status (SES), social insurance, the area resided, ethnicity, parental educational level, and SES at birth. RESULTS The risk of onset of PEs was significantly higher in lower education, lower SES, and slum-semi-urban areas. The persistence of PEs was significantly associated with the lowest levels of education and current SES, and rural residency. Persistent PEs were significantly and negatively associated with paternal SES at birth. Progression of PEs was significantly higher among respondents with educational achievements lower than university level and lower levels of SES, who have no social insurance and who reside in slum-semi-urban areas. Parental education and paternal SES at birth were not associated with the persistence of PEs. CONCLUSION Indicators of social inequality (low education, low SES, low income, and poverty in the neighbourhood) were associated with the onset and persistence of PEs and progression along the extended psychosis phenotype. The early indicators seem to have a modest life-long impact on the psychosis phenotype.

Abstract
BACKGROUND AND HYPOTHESES A wealth of evidence suggests that adolescent psychotic experiences (PEs), and especially auditory hallucinations (AHs), are associated with an increased risk for self-injurious behavior (SIB). However, the directionality and specificity of this association are not well understood, and there are no published studies investigating within-person effects over time. The present study aimed to test whether AHs and SIB prospectively increase reciprocal risk at the individual level during early-to-middle adolescence. STUDY DESIGN Three waves (12y, 14y, and 16y) of self-reported AHs and SIB data from a large Tokyo-based adolescent birth cohort (N = 2825) were used. Random Intercept Cross-Lagged Panel Model (RI-CLPM) analysis was conducted to test the within-person prospective associations between AHs and SIB. STUDY RESULTS At the within-person level, AHs were associated with subsequent SIB over the observation period (12y-14y: β = .118, P < .001; 14-16y: β = .086, P = .012). The reverse SIB->AHs relationship was non-significant at 12-14y (β = .047, P = .112) but emerged from 14y to 16y as the primary direction of influence (β = .243, P < .001). Incorporating depression as a time-varying covariate did not meaningfully alter model estimates. CONCLUSIONS A complex bi-directional pattern of relationships was observed between AHs and SIB over the measurement period, and these relationships were independent of depressive symptoms. Adolescent AHs may be both a predictor of later SIB and also a manifestation of SIB-induced psychological distress.

Abstract
Background: Psychotic symptoms are present in a wide range of both clinical and non-clinical populations. Psychotic symptoms in adolescents often take the form of psychotic-like experiences (PLEs), which are considered a risk factor for numerous serious mental illnesses. Socioeconomic disadvantages are across rural areas, and poverty is known as the third most important risk factor of PLEs. However, there have been limited studies on PLEs which focus on populations in rural areas.Objective: The aim of this study was to assess the prevalence of PLEs and investigate their predictors among early adolescents living in rural areas.Method: Data from 629 early adolescents from two rural areas in Indonesia were analysed using descriptive statistics to determine the prevalence of PLEs. Multiple logistic regression analysis was used to assess the predictors of PLEs. This was a school-based cross-sectional study, and data were collected using a paper questionnaire.Results: The results showed that the prevalence of PLEs among early adolescents in rural areas is 24.5%. Four significant predictors of PLEs were identified after controlling for sex: emotional problems, age, the number of caregivers in daily life, and psychological well-being.
