Despite the established co-prevalence of substance use (SU) and disordered eating (DE), few longitudinal studies have sought to examine their shared development. Findings have been inconsistent within the extant literature. This may be attributable in part to several methodological aspects, including overlooking distinct psychopharmacological properties of common substances of abuse, examining only between-person relations, and failing to account for shared risk factors. The current study sought to address these gaps by applying latent curve models with structured residuals (LCM-SR) to a preexisting, national sample of adolescent girls followed into adulthood, Add Health. In Aim 1, between-person effects examined the simultaneous development of alcohol, tobacco, and marijuana use and DE behaviors in substance-specific models. In Aim 2, bivariate latent curve models were expanded to account for within-person effects (LCM-SR) in order to examine the potentially bidirectional, prospective relationship between use of a specific substance and DE. Lastly, models accounted for shared developmental risk factors. Findings of the current study demonstrate preliminary evidence of substance-specific effects with DE emerging in adolescence. Across model-building steps, DE engagement in early adolescence was significantly associated with growth in tobacco use and marginally associated with marijuana use. Appetitive side-effects of both substances may link use with DE behaviors and enhance instrumental use for weight control. Significant associations did not emerge between alcohol and DE, and results of the conditional model indicate this co-occurrence is best explained by third variable mechanisms. Implications for prevention are discussed.

When a sports performance is at its peak, it is akin to a musical performance in the sense that each player seems to perform their part effortlessly, creating a rhythmic flow of counterparts all moving as one. Rhythm and timing are vital elements in sports like basketball in which syncopated passing and shooting appear to facilitate accuracy. This study tests if shooting baskets “in rhythm,” as measured by the catch-to-release time, reliably enhances shooting accuracy. It then tests if an “in rhythm” timing is commonly detected and agreed upon by observers, and if observer timing ratings are related to shooting accuracy. Experiment 1 tests the shooting accuracy of two amateur basketball players after different delays between catching a pass and shooting the ball. Shots were taken from the three-point line (180 shots). All shots were recorded and analyzed for accuracy as a function of delay time, and the recordings were used to select stimuli varying in timing intervals for observers to view in Experiment 2. In Experiment 2, 24 observers each reviewed 17 video clips of the shots to test visual judgment of shooting-in-rhythm. The delay times ranged from 0.3 to 3.2 seconds, with a goal of having some of the shots taken too fast, some close to in rhythm, and some too slow. Observers rated if each shot occurs too fast, in rhythm slightly fast, in rhythm slightly slow, or too slow. In Experiment 1, shooters exhibited a significant cubic fit with better shooting performance in the middle of the timing distribution (1.2 sec optimal delay) between catching a pass and shooting. In Experiment, 2 observers reliably judged shots to be in rhythm centered at 1.1 ± 0.2 seconds, which matched the delay that leads to optimal performance for the shooters found in Experiment 1. The pattern of findings confirms and validates that there is a common “in rhythm” catch-to-shoot delay time of a little over 1 second that both optimizes shooter accuracy and is reliably recognized by observers.

Midlife is a unique period of development during which individuals are simultaneously engaging in multiple roles. Despite this, there is a surprisingly small amount of research on this period of the life course. In order to examine sources of adversity during this period, we analyzed interviews with individuals in midlife about their greatest challenge. The most common themes for types of adversity included relationships, health, and work, reflecting the unique combination of roles in midlife.

Exploration of a mouse model (C57BL/6J) capable of demonstrating behavioral changes after adolescent social isolation that are consistent with prior findings may prove beneficial in later research. This study examined 2 proposed long-term effects of isolated housing (one mouse/cage), when compared to group housing (two mice/cage) during adolescence. Mice were placed in their respective housing conditions after weaning (PND 21) and remained in those conditions until PND 60. The same cohorts were used in both phases of the experiment. Phase 1 sought to confirm previous findings that showed increases in ethanol intake after adolescent social isolation using a 2-bottle preference Drinking-in-the-Dark (DID) design over a 4-day period (PND 64-PND 67.). Phase 2 sought to elucidate the effects present after adolescent social isolation, as measured using response inhibition capabilities demonstrated during fixed-minimum interval (FMI) trials (PND 81-PND 111). Findings in phase 1 of the experiment were non-significant, save a strong tendency for female mice in both housing conditions to drink more as a proportion of their bodyweight (g/kg). However, a trend of lower bodyweight in single housed mice did exist, which does suggest that detrimental stress was applied via the used of adolescent isolation in that housing condition. Findings in phase 2 showed little effect of adolescent social isolation on mean inter-response time (IRT) at any criterion used (FMI-0, FMI-4, FMI-6). Evaluation of mean interquartile range (IQR) of IRTs showed a significantly greater amount of variation in IRT responses within single housed mice at the highest criterion (FMI-6), and a trend in the same direction when FMI-4 and FMI-6 were tested concurrently. Taken as a whole, the findings of this experiment suggest that the effect of adolescent social isolation on ethanol intake is far less robust than the effect of sex and may be difficult to replicate in a low-power study. Additionally, adolescent social isolation may interfere with the ability of mice to show consistent accuracy during FMI tasks or a delay in recognition of FMI criterion change.

In the past year, considerable misinformation about the COVID-19 pandemic has circulated on social media platforms. Faced with this pervasive issue, it is important to identify the extent to which people are able to spot misinformation on social media and ways to improve people’s accuracy in spotting misinformation. Therefore, the current study aims to investigate people’s accuracy in spotting misinformation, the effectiveness of a game-based intervention, and the role of political affiliation in spotting misinformation. In this study, 235 participants played a misinformation game in which they evaluated COVID-19-related tweets and indicated whether or not they thought each of the tweets contained misinformation. Misinformation accuracy was measured using game scores, which were based on the correct identification of misinformation. Findings revealed that participants’ beliefs about how accurate they are at spotting misinformation about COVID-19 did not predict their actual accuracy. Participants’ accuracy improved after playing the game, but democrats were more likely to improve than republicans.

Shared Parenting: From Practice to Policy

This study examines how a 2013 Arizona law on shared parenting would affect living arrangements, and thus mental health measures. There were two hypotheses. According to the Law Change Hypothesis, it was hypothesized that parenting time in Arizona would be more equal following the 2013 Arizona law change while there would be no change in parenting time in other states following the 2013 Arizona law change. It was further hypothesized that child mental health would be better after the law change in Arizona with no change being seen in other states. Results of this study were almost completely inconsistent with the hypothesis. According to the Law Reflect Hypothesis, the law is actually reflecting the behavior of the community and their thoughts on equal parenting time becoming more favorable, and therefore a change towards more equal parenting time would be found prior to 2013 in Arizona with no change seen in other states. Furthermore, as the Arizona community’s behavior changed, child mental health would be better with no change being seen in other states. Regressions found that a small change toward more equal parenting and closeness with father was prior to 2013 for Arizona students, compared to out-of-state students, although it did not find that the year of divorce resulted in less anxiety, stress, and depression. This partially agrees with past research that the 2013 law is working as intended, even if it started working earlier than we thought. This does not agree with previous research stating there is a connection between equal parenting and better mental health. This is important because this study questions the efficacy of an important and controversial policy. If future studies are consistent with this one, the effectiveness of the Arizona 2013 law change on mental health will need to be further evaluated.

Description

People generally struggle with making good decisions for their well-being (Hershfield, 2019; Hershfield & Bartels, 2018). One reason for this might be that people struggle with connecting to their future selves. Prior research suggests that future self-connectedness predicts better decisions.

People generally struggle with making good decisions for their well-being (Hershfield, 2019; Hershfield & Bartels, 2018). One reason for this might be that people struggle with connecting to their future selves. Prior research suggests that future self-connectedness predicts better decisions. This study examined if feeling more positive or negative helps people connect more to their future self and if this, in turn, helps people make better decisions. Participants read a scenario in which they are presented with two decisions, one having a short-term benefit/long-term cost and the other having a short-term cost/long-term benefit. Either neutral affect framing, positive affect framing, or negative affect framing was emphasized in the scenario depending on the condition. Our study did not find that positive affect framing and negative affect framing enhanced future self-connectedness. Neither did we find that positive affect framing and negative affect framing influenced decision-making.

Using data from a randomized, experimental trial of a brief family-based preventive intervention for parentally-bereaved families, this study evaluated whether participation in the Family Bereavement Program (FBP) when the offspring were in childhood/adolescence (ages 8 to 16) improved competencies when the offspring were emerging/young adults (ages 23 to 32). Participants were 244 emerging/young adults; data used were from assessments at pretest, posttest, 6 years post-intervention, and 15 years post-intervention. In addition to testing the direct effects of the program, developmental cascade effects models were used to test the relations between program-induced improvements in positive parenting and decreased negative life events at posttest and subsequent effects on domains of competence and behavior problems in adolescence/emerging adulthood (ages 14 to 22) and four developmental competencies of emerging/young adulthood: academic, peer, romantic, and work competence. Results supported a cascading effects model of program effects on competence outcomes. In the full sample, there were significant mediation effects of the intervention to decreased negative life events at posttest to increased grade-point average (GPA) at the 6-year follow-up to higher academic and work competence at the 15-year follow-up. For females only, two additional significant mediational pathways of the FBP occurred. The FBP led to an increase in peer competence 6 years post-intervention, which was associated with an increase in work competence 15 years post-intervention. Also, the FBP led to a decrease in externalizing problems in adolescence/emerging adulthood, but externalizing problems were positively associated with work competence. For males, additional mediation effects of the FBP on work competence occurred. The FBP decreased negative life events. However, higher negative life events were associated with lower externalizing problems in adolescence/emerging adulthood, and externalizing problems were positively associated with work competence. For males only, a significant three-pathway mediation effect of the intervention occurred on increased positive parenting at posttest to increased romantic attachment at the 6-year follow-up to higher romantic competence at the 15-year follow-up. Peer competence showed continuity over development. Mediational analyses highlighted the role of program-induced improvements in parenting, reductions in exposure to negative life events, and earlier developmental competencies on competence outcomes in emerging/young adulthood. Implications for promoting resilience in parentally-bereaved, at-risk youth are discussed.

Prior research has established a relation between parenting behaviors and symptoms of child psychopathology, and this association may be influenced by both genetic and environmental factors. Gene-environment correlation, or the influence of a child’s genes on the environment they receive, represents one possible mechanism through which genes and environment combine to influence child outcomes. This study examined evocative gene-environment correlation in the relation between parenting and symptoms of child psychopathology in a sample of 676 twins (51.5% female, 58.5% Caucasian, 23.7% Hispanic/Latinx, primarily middle class, MAge=8.43, SD=.62) recruited from Arizona birth records. Using univariate ACE twin biometric models, genetic influences were found to moderately contribute to internalizing symptoms (A=.47, C=.25, E=.28), while externalizing (A=.86, E=.14) and ADHD (A=.84, E=.16) symptoms were found to be highly heritable. The genetic influences for positive (C=.54, E=.46) and negative (C=.44, E=.56) parenting were smaller and found to be nonsignificant. The correlations between parenting and types of psychopathology were examined and bivariate Cholesky decompositions were conducted for statistically significant correlations. Negative parenting was moderately positively correlated with externalizing and ADHD symptoms; the relation between externalizing symptoms and negative parenting was found to be due to shared genetics, whereas the relation between negative parenting and ADHD symptoms was due to the shared environment. The mixed results regarding the role of gene environment correlation in relations between parenting and child psychopathology indicate that further research on the mechanisms of this relation is needed.
