OBJECTIVE: To investigate whether changes in volunteering from adolescence to young adulthood are associated with subsequent health and well-being outcomes in adulthood.
METHODS: Longitudinal cohort study.
METHODS: National Longitudinal Study of Adolescent to Adult Health.
METHODS: U.S. adults from Wave IV (2008/2009; N = 12,234) and Wave V (2016-2018; N = 9,971).
METHODS: Any volunteering and nine types of volunteering (independent variables) and 41 health and well-being outcomes (dependent variables) using an outcome-wide approach with multiple linear-, logistic-, and generalized linear regressions.
RESULTS: Volunteering in young adulthood was associated with better health behaviors (e.g., 34% decreased risk of binge drinking, 95% CI [0.54, 0.81]) and improved psychosocial and civic outcomes (e.g., lower depressive symptoms (β = -0.08, 95% CI [-0.14, -0.02]) in adulthood. Volunteering showed little evidence of associations with other health and well-being outcomes (e.g., loneliness, (β = -0.04, 95% CI [-0.09, 0.01])). Assessing volunteering by organization types showed a range of positive and negative outcomes. For example, volunteering in hospitals/nursing homes was associated with a 36% increased risk of high cholesterol (95% CI [1.06, 1.73]) and volunteering with political clubs was associated with a 52% increased risk of an anxiety diagnosis (95% CI [1.13, 2.05]).
CONCLUSIONS: Our findings suggest more work is needed to determine the conditions under which volunteering is health promoting and to minimize potential adverse effects associated with some types of volunteering.

Previous research has shown a robust association between different childhood and adolescent vulnerabilities and youth offending. However, these investigations have primarily focused on youths from high-income Western countries. Consequently, the generalizability of these findings to better inform global justice policies remains uncertain. This study aimed to address this gap by examining the relationship between individual, familial, and contextual vulnerabilities and criminal versatility during young adulthood, accounting for sociodemographic factors and cross-national differences. Data were derived from a diverse sample of 4,182 young adults (67% female; mean age = 18.96; SD = 0.81) residing in 10 countries across 5 continents who participated in the International Study of Pro/Antisocial Behavior in Young Adults. The Psychosocial and Family Vulnerability Questionnaire and the Adverse Childhood Experiences questionnaire were used to assess social and family adversity, and past-year criminal diversity was measured with the Criminal Variety Index. Results indicate that child maltreatment, substance abuse, and delinquent peers are global risk factors for criminal variety. Moreover, they are independent across males and females and among youths living in countries that are ranked differently on the Human Development Index (HDI). In addition, some childhood vulnerabilities showed different predictive ability across sexes (e.g., school failure), and across countries ranked differently on the HDI (e.g., family dysfunction). These findings suggest that certain childhood factors contribute to criminal behavior through transcultural mechanisms. Moreover, they highlight the importance of developing evidence-based policies that focus on transcultural risk factors to globally prevent criminal behavior.

UNASSIGNED: The transition to young adulthood can be a turbulent life stage, and this is often magnified for autistic youth. Young adults frequently profess different goals and values than their parents. While there is some indication in autism research about how parents, and to a lesser extent, autistic young adults, feel about this transition, little research leverages dyadic interviews with both populations or has used this method with Black and/or low-income families.
UNASSIGNED: We conducted four sets of dyadic interviews with autistic young adults and their parents who live together.
UNASSIGNED: We identified three key themes that both groups found important to the transition: independence, structured transition, and interpersonal relationships. However, we found that how the groups conceptualized these themes were divergent and revealed differences in goals and values. Parents were more oriented toward long-term normative views of fulfillment, whereas young adults spoke about what was meaningful to them currently.
UNASSIGNED: This work has implications for changes to how autism research will conceptualize the transition to young adulthood and how we can create better social opportunities for this population.
UNASSIGNED: Why is this an important issue?: Autistic adults are at risk for difficulties getting work and education, which can lead to them feeling alienated or unfulfilled. Most research on autistic people becoming adults is based on White people with more cultural and financial resources and does not ask autistic people themselves or their families with them. Research is needed to improve transition outcomes for these underresearched and underserved groups.What was the purpose of this study?: This study explored how autistic youth and their parents thought about and experienced the transition to adulthood out of an urban, low-resourced school district.What did the researchers do?: Researchers interviewed four parents and four autistic youth. Three families were Black, and one family was White and from a low-income household. All autistic youth had received special education services, needed support to transition to adulthood, and had finished high school 1 to 6 years before the study. The young adults lived with their mothers and received support from them for daily tasks. We interviewed the parents and then the youth. In some cases, youths joined parents\' interviews or parents joined youths\' interviews to provide help with remembering information or giving answers.What were the results of the study?: Researchers identified three themes. First, parents and youth thought about independence differently. Parents focused more on work and financial independence. Youth focused more on social aspects of work and having independence in daily activities such as shopping. The second theme was that youth and parents approached ongoing structured supports differently. Youth reported positive experiences with a range of services but did not discuss the need for ongoing supports like their parents did. Third, youth emphasized the importance of social relationships and opportunities to connect with peers through shared interests.What do these findings add to what was already known?: We learned that standard questions about transition may not reflect how autistic youth and their parents think about becoming an adult. Interviewing families coming out of a predominantly Black and low-income urban school district helped us to understand how these groups experience and think about the transition to adulthood, even though they did not use these identities as a logic for how they thought about young adulthood. This suggests that parent and youth perspectives differ in groups that are not usually well represented in research studies related to transition for autistic youth.What are potential weaknesses in the study?: This study only included a small number of youth and parents. These results do not represent all Black autistic youth or low-income autistic youth coming from urban school districts. Families who are less connected to services may have been less likely to hear about or take part in the study.How will these findings help autistic adults now or in the future?: These findings could inform the development of better interviewing approaches and research to address the needs of diverse autistic youth entering adulthood. This work could improve transition support. Parents, youth, support providers, and researchers may think about adulthood differently. Improved support could help build mutual understanding and coordination around youths\' and their families\' goals.

OBJECTIVE: Studies on adolescent alcohol use and cognition are often unable to separate the potential causal effects of alcohol use on cognition from shared etiological influences, including genetic influences or other substance use comorbidities also known to be associated with cognition, such as nicotine use. The present study aimed to fill this gap and clarify the relationship between adolescent alcohol use and young adult cognition by accounting for both measured and unmeasured confounders.
METHODS: A random effects model accounting for nesting in families was used to control for measured confounders. Next, co-twin comparisons were conducted within the full sample and in monozygotic twin pairs (MZ) to control for unmeasured genetic and environmental confounders shared by co-twins.
METHODS: Participants were 812 individuals (58.6% female, 361 complete pairs, 146 MZ pairs) from the longitudinal FinnTwin12 study in Finland.
METHODS: Adolescent alcohol use was indexed with measures of frequency of use and intoxication averaged across ages 14 and 17. Cognitive outcomes were measured at average age 22 and included Trail Making Test, California Stroop test, Wechsler Adult Intelligence subtests (Vocabulary, Block Design, Digit Symbol), Digit Span subtest of Wechsler Memory Scale, Mental Rotation Test and Object Location Memory test. Covariates included sex, parental education, general cognitive ability, current alcohol use and nicotine use.
RESULTS: Greater frequency of alcohol use and frequency of intoxication across adolescence was associated with decreased vocabulary scores in the co-twin control [freq: stnd beta = -0.12, 95% confidence interval (CI) = -0.234, -0.013] and MZ only co-twin control models (freq: stnd beta = -0.305, 95% CI = -0.523, -0.087; intox: stnd beta = -0.301, 95% CI = -0.528, -0.074).
CONCLUSIONS: In Finland, there appears to be little evidence that adolescent alcohol use causes cognitive deficits in young adulthood, except modest evidence for association of higher adolescent alcohol use with lower young adult vocabulary scores.

BACKGROUND: Participation in occupations is considered essential for individuals\' health and wellbeing. Participation is a multidimensional construct that encompasses objective and subjective dimensions that transform over the course of life. Nonetheless, there is a lack of comprehensive measures that examine young adults\' participation in age-appropriate activities. Therefore, we developed the Young Adults\' Daily Participation Scale (YADAPS) and aimed to explore its psychometric properties.
METHODS: In Study 1, the content validity of the YADAPS was established based on nine experts. Its internal consistency, criterion, convergent, and construct validity were explored among 115 typical young adults (21-35 years). Using a different sample, Study 2 examined YADAPS discriminant validity among 33 young adults with developmental coordination disorder (DCD) and 52 typical peers.
UNASSIGNED: No consumer and community involvement was included in these studies.
RESULTS: The relevance of YADAPS items was sufficient. Internal consistency was acceptable to excellent in most scales (.74 ≤ α ≤ .89). Criterion validity was supported by correlations between the subjective participation scales and a wellbeing measure. Convergent validity was found for all scales. No gender effect was observed (p ≥ .05). However, significant differences (p ≤ .05) were found between individuals with and without DCD.
CONCLUSIONS: The YADAPS appears to be a promising measure of objective and subjective dimensions of participation in young adults. The results support the importance of examining various participation dimensions, including occupational experience. Thus, it may be used for clinical purposes among young adults as well as for occupational science research, to broaden our understanding on the interplay between participation dimensions in various life situations in young adulthood. However, further research is needed on psychometric properties, the most suited scoring method, and to consolidate their robustness among diverse populations of young adults.
CONCLUSIONS: Participation, or how one engages in daily life activities, greatly affects wellbeing. The activities in one\'s routine change over the lifespan, in accordance with one\'s developmental phase. Existing assessments of participation have limitations, like not considering young adults\' concerns or only focussing on certain aspects of participation. By focussing on both the objective-observable and subjective-experiential aspects of participation, the Young Adults\' Daily Participation Scale (YADAPS) strives to be a comprehensive assessment tool designed specifically for reflecting activities relevant in young adulthood. This manuscript provides preliminary validity and reliability for the YADAPS, a new questionnaire that assesses objective and subjective aspects of participation in activities relevant for individuals in young adulthood. Furthermore, the questionnaire is able to distinguish between young adults with and without participation difficulties; therefore, it is suitable for research and clinical use.

Young adults face stressful role transitions as well as increased risk for poor mental health, but little is known about a \"natural course\" of response to such events. We used the PHQ-2 to characterize the trajectory of depressive symptoms before, during, and after relationship breakup and examined subjective appraisal and sense of control as moderators. In our sample of participants reporting a single breakup during the 2-year study period (N=156), breakup was associated with a temporary increase in depressive symptoms that returned to pre-breakup levels within three months. We observed increased symptoms among negatively appraised, but not positive or neutral, events. A general low sense of control was associated with higher depressive symptoms at all time points. Our results suggest that a natural course of response to young adult breakups is characterized by recovery within three months and that subjective appraisal and sense of control contribute to this adaptive response.

UNASSIGNED: To estimate the extent to which drinking to cope with the COVID-19 pandemic and experiencing pandemic-related life stressors are associated with alcohol use escalation among young adults.
UNASSIGNED: Respondents in Los Angeles, CA, USA (N=2,130) completed prospective cohort study surveys before (baseline; October 2018-November 2019; mean age: 19.7[SD=0.4) and during (follow-up; May-August 2020) the COVID-19 outbreak. Past 30-day drinking days and number of drinks per drinking day were assessed from baseline to follow-up. At follow-up, participants reported drinking to cope with social isolation and pandemic-related stressors.
UNASSIGNED: Pandemic-related stressor prevalence ranged from 5.5% (evicted/lost home) to 72.6% (worried about education) and 27.1% drank to cope with social isolation during the pandemic. Respondents who did (vs. did not) report pandemic-related coping drinking were more likely to increase past 30-day drinking days and drinks per drinking day from baseline to follow-up after adjustment for possible confounders. Employment loss/reduction, financial problems, and perceived likelihood of contracting COVID-19 or handling the pandemic poorly were each associated with increases in drinking days or drinks per drinking day.
UNASSIGNED: Experiencing certain life stressors and drinking to cope with social isolation may be associated with drinking escalation among young adults during the COVID-19 pandemic.

OBJECTIVE: Parental interpartner conflict is a highly prevalent form of family risk that is stressful for adolescents with ramifications for their sleep. Multiple studies have demonstrated that adolescents from high-conflict homes are at risk for sleep problems. Building on this literature, we conducted novel analyses and investigated whether exposure to interpartner conflict in adolescence predicts sleep problems in the subsequent developmental period of emerging adulthood.
METHODS: We used a rigorous four-wave design spanning 8years (collected between 2012-2020). At wave 1, participants were 245 adolescents from diverse backgrounds (M age=15.74years; 67% White/European American, 33% Black/African American; 52% girls). Individuals participated again in their adolescence at wave 2 (M age=16.77) and wave 3 (M age=17.69). Participants returned for wave 4 in emerging adulthood (M age=22.97). Adolescents reported on their parents\' interpartner conflict (intense and frequent conflict). Sleep duration (minutes) and quality (efficiency, long wake episodes) were measured using actigraphy.
RESULTS: After controlling for autoregressive effects and several covariates, findings from a structural equation model revealed that greater exposure to parental interpartner conflict in adolescence predicted reduced sleep efficiency and more long wake episodes in emerging adulthood.
CONCLUSIONS: Results build on the literature to consider sleep in the family context and are among the first to illustrate that exposure to parental interpartner conflict in adolescence predicts sleep problems in emerging adulthood. Continued investigations into the antecedents of sleep problems in emerging adulthood may benefit from considering past exposure to family risk.

UNASSIGNED: Depression, anxiety, and stress are persistent and co-occurring symptoms in survivors of childhood traumatic brain injury (TBI), and often impact on health-related quality of life (HRQoL). This paper explored emotional distress symptom clusters and associated factors in young adults with childhood TBI.
UNASSIGNED: We included 54 young adults who sustained mild (n = 14), moderate (n = 27), and severe (n = 13) childhood TBI, at 20 years post-injury. The Depression Anxiety Stress Scale was administered. Cluster group membership was identified using two-step clustering and hierarchical clustering methods, and associated factors were assessed with multiple regression models.
UNASSIGNED: Two symptom cluster groups were identified, including a No Distress (n = 66%) and an Elevated Distress (n = 33%) group, with the latter showing significantly higher symptoms of depression, anxiety, and stress (all p < .001). Elevated Distress group membership was linked to tobacco use and poor sleep quality, while poor HRQoL was associated with younger age at injury and Elevated Distress group membership.
UNASSIGNED: Using cluster methodology, we showed that one-third of young adults with childhood TBI had elevated emotional distress symptoms. This underscores the complex emotional profile of this subgroup and the need for assessment, analysis, and treatment methods that target a range of symptoms rather than relying on single-diagnostic protocols.

BACKGROUND: This study adopts individual and societal-level approaches to examine the contribution of childhood risk factors to major depressive episodes (MDE) in 2526 American young adults.
METHODS: Nationally representative data from the 2017 U.S. Panel Study of Income Dynamics - Transition into Adulthood Supplement (PSID-TAS) were analyzed using multivariate methods to assess the impact of parental mental illness, childhood adversities, childhood mental disorders, and childhood physical conditions. Adjusted odds ratios and population attributable risk proportions (PARPs) are calculated to estimate the proportion of MDE cases related to risk factors.
RESULTS: The 12-month prevalence of positive screens for MDE was 25.4 %. Approximately 34 % of these were attributable to childhood mental disorders, 24 % to childhood physical conditions, 21 % to childhood adversities, and 16 % to parental mental illness. Childhood and parental depression were critical risk factors, both at the individual (odds ratio exceeding 2) and societal (PARP approximately 24 %) levels. Gender-specific risk factors were identified, with childhood physical abuse and childhood anxiety disorders constituting risk factors for females, and childhood externalizing disorders and childhood headaches as risk factors for males. Approximately 60 % of U.S. young adult MDE cases are attributable to risk factors before age 18.
CONCLUSIONS: Possible over reporting of MDE may have biased the associations between predictors and depression.
CONCLUSIONS: Exposure to depression at a young age-one\'s own or parental depression-is a robust risk factor for both genders. Policies and interventions focused at alleviating the societal burden of depression should value its generational transmission.
