Analysis of resting state fMRI (rs-fMRI) typically excludes images substantially degraded by subject motion. However, data quality, including degree of motion, relates to a broad set of participant characteristics, particularly in pediatric neuroimaging. Consequently, when planning quality control (QC) procedures researchers must balance data quality concerns against the possibility of biasing results by eliminating data.

Background: Cumulative risk scores predict negative outcomes including antisocial behaviour and mental health. Less work has examined the role of cumulative protection, despite the availability of preventive interventions focused on bolstering protection across domains. Understanding links between cumulative risk and protection measured in childhood and later outcomes can help to guide the timing of prevention programmes.

Article Synopsis
  • The research highlights that the prevalence of electronic nicotine delivery systems (ENDS) among young adults matches that of traditional cigarettes, indicating a need for tailored prevention strategies that address specific risk and protective factors (RPFs) for each.
  • Using data from the Community Youth Development Study involving over 4,000 participants, the study explores how general protective factors and substance-specific RPFs influence young adult use of both cigarettes and ENDS from early adolescence to young adulthood.
  • Findings reveal that while general protective factors can indirectly affect young adult nicotine use, targeted interventions focusing on cigarette-specific beliefs and peer substance use are necessary for effective prevention of both cigarette and ENDS use.

Little is known about the impacts of living in diaspora from the Hawaiian Islands on Native Hawaiian health. To address this, the authors conducted an exploratory analysis using cross-sectional data from the 2021 Native American COVID-19 Alliance Needs Assessment. A total of 1418 participants identified as Native Hawaiian (alone or in any combination), of which 1222 reported residency in the continental US and 196 in Hawai'i.

Objective: Test whether global self-reports of urgency moderated the within-person associations of affect and impulsive behaviors.

Background: Negative urgency is a personality trait that is a risk factor for a range of psychopathology. Although it is assumed that global self-reports of urgency measure individual tendencies to act more impulsively in the face of negative emotions, evidence from ecological momentary assessment studies is mixed.

Objective: An aim of quantitative intersectional research is to model the joint impact of multiple social positions on health risk behaviors. Although moderated multiple regression is frequently used to pursue intersectional research hypotheses, such parametric approaches may produce unreliable effect estimates due to data sparsity and high dimensionality. Machine learning provides viable alternatives, offering greater flexibility in evaluating many candidate interactions amid sparse data conditions, yet remains rarely employed.

Background And Aims: For young adults, the disruptions brought by the COVID-19 pandemic to work, social relationships and health-care probably impacted normative life stage transitions. Disaster research shows that negative effects of these events can persist for years after the acute crisis ends. Pandemic-related disruptions may have been especially consequential for young adults with a history of substance use disorder (SUD).

Evidence suggests that loneliness causes people to feel more depressed. It is unknown, however, why this association occurs and whether momentary versus chronic experiences of loneliness are implicated. Theoretical accounts suggest that momentary feelings of loneliness produce two competing motivations: social reaffiliation and social withdrawal.

Objective: There is inconclusive evidence regarding sexual identity and race/ethnicity differences in outcomes in evidence-based psychological treatments. Although dialectical behavior therapy (DBT) is well-studied, little is known about the extent to which its efficacy generalizes to sexual minority and racial/ethnic minority people. This study examined sexual identity, race/ethnicity, and their interaction as predictors of treatment outcome and retention in DBT.

Objective: The Acquired Preparedness (AP) model proposes that impulsive personality traits predispose some individuals to learn certain behavior-outcome associations (expectancies), and that these expectancies in turn influence the escalation of risky behaviors. This theory has been applied to the development of behaviors such as drinking, drug use, gambling, and disordered eating. In the current study, we aimed to summarize empirical tests of this model over the 20 years since it was proposed.

Negative emotionality and effortful control consistently predict child adjustment, yet few studies explore their interactive effects on adjustment. In concurrent and longitudinal (one-year follow-up) analyses, we examined negative emotionality-by-effortful control interactions in predicting anxiety, depression, and conduct problems in 214 children aged 8-12. Temperament was assessed using behavioral tasks measuring fear, frustration, executive control, and delay ability.

Objective: Generalized linear models (GLMs) such as logistic and Poisson regression are among the most common statistical methods for modeling binary and count outcomes. Though single-coefficient tests (odds ratios, incidence rate ratios) are the most common way to test predictor-outcome relations in these models, they provide limited information on the magnitude and nature of relations with outcomes. We assert that this is largely because they do not describe direct relations with quantities of interest (QoIs) such as probabilities and counts.

Psychology research frequently involves the study of probabilities and counts. These are typically analyzed using generalized linear models (GLMs), which can produce these quantities via nonlinear transformation of model parameters. Interactions are central within many research applications of these models.

There is a small body of research that has connected individual differences in negative urgency, the tendency to report rash actions in response to negative emotions, with self-report depressive and anxiety symptoms. Despite the conceptual overlap of negative urgency with negative emotionality, the tendency to experience frequent and intense negative emotions, even fewer studies have examined whether the association of negative urgency with internalizing symptoms hold when controlling for negative emotionality. In the current study, we estimated the bivariate association between negative urgency and internalizing symptoms, tested whether they remained significant after partialling out negative emotionality, and tested whether these effects generalized to real-time experiences of negative emotions.

Objectives: Psychological science has taken up investigations of the effectiveness of mindfulness-based programs (MBPs) and mechanisms through which people benefit from mindfulness. Reliable and valid psychometric tools are essential components of psychological science, and efforts have been made to produce tools for the accurate measurement of mindfulness as a construct. However, trait measurement methods, which are commonly used, may not adequately assess mindfulness and mental health outcomes in a way that allows for mechanisms to be adequately tested.

Emerging evidence suggests impulsive states may be reliably measured in the moment using ecological momentary assessment (EMA); however, research has not investigated whether the multi-factor structure of impulsive traits also characterizes impulsive states. In two independent samples spanning adolescence through young adulthood ( = 211, = 222), we adapted global self-report measures of impulsive traits to EMA and conducted multilevel confirmatory factor analyses to characterize the within- and between-person factor structure of five impulsive traits (negative urgency, planning, persistence, sensation seeking, and positive urgency). Across both studies, factor models with one factor for each UPPS-P facet fit the data well at both levels, though some latent factors were highly correlated.

There are stable between-person differences in an internalizing "trait," or the propensity to experience symptoms of internalizing disorders, such as social anxiety, generalized anxiety disorder, and depression. Trait internalizing may serve as a marker of heightened risk for problem alcohol outcomes (such as heavier drinking, binge drinking, or alcohol dependence). However, prior research on the association between internalizing symptoms and alcohol outcomes has been largely mixed in adolescence, with more consistent support for an association during adulthood.

We reexamined the psychometric properties of the Momentary Impulsivity Scale (MIS) in two young adult samples using daily diary (=77) and ecological momentary assessment (=147). A one-factor between- and within-person structure was supported, though "I felt impatient" loaded poorly within-person. MIS scores consistently related to emotion-driven trait impulsivity; however, MSSDs of MIS scores were unrelated to outcomes after accounting for aggregate MIS scores.

Background: Depression is the leading cause of disability and represents a significant challenge to stable employment and professional success. Importantly, employment may also operate as a protective factor against more chronic courses of depression as it can function as a form of behavioral activation and scaffold recovery by facilitating community integration. The current study examined work-related characteristics as protective or risk factors for subsequent long-term depression trajectories.

Historically, mentorship has been conceived of as a dyadic relationship between a senior mentor and an early-career investigator. Models involving multiple mentors have gained favor in recent years, but empirical research on multiple-mentor models has been lacking. The current work aims to fill this gap by describing a long-standing health services research mentoring program at the U.
