Sibling Constructs: What Are They, Why Do They Matter, and How Should You Handle Them?

Researchers often study constructs that are conceptually and/or empirically related, but distinct (i.e., "sibling constructs"). In social-personality psychology, as well as psychology more generally, there is little guidance for how to deal with sibling constructs, which can result in researchers ignoring or mishandling them. In this article, we start by situating sibling constructs in the literature on the jingle-jangle fallacies. Then, we outline 10 conceptual and empirical criteria for determining the degree to which, and in what ways, constructs may share a sibling relationship, using self-esteem and grandiose narcissism as a running example. Finally, we discuss strategies for handling sibling constructs in a systematic and transparent way. We hope that the procedures described here will help social-personality psychologists identify sibling constructs, understand when and why they pose problems for their research, and adopt strategies that ameliorate their adverse effects.

Do temperament trajectories from late childhood through adolescence predict success in school? Findings from a longitudinal study of Mexican-origin youth.

School achievement has long-term consequences for occupational success, mental health, and overall psychological adjustment. The present study examined the association between temperament trajectories from late childhood through adolescence and academic outcomes during late adolescence and young adulthood. Data come from the California Families Project, a longitudinal study of 674 Mexican-origin youth assessed 12 times from Age 10 to 23, and from school records. Results from latent growth curve models indicate that higher levels of Effortful Control (EC) at Age 10 were associated with better academic achievement (i.e., higher high school grade point average and test scores, greater likelihood of high school graduation and college attendance) in late adolescence and young adulthood. Higher levels of Negative Emotionality (NEM) at Age 10 were associated with worse academic achievement, but this effect did not hold for all facets of NEM. Neither the levels nor slopes of Positive Emotionality (Surgency, Affiliation) consistently predicted school achievement. There were no main effects of the EC or NEM slopes; however, statistically significant interactions between these slopes and parental monitoring emerged. When parental monitoring was low, youth who experienced greater increases in EC (vs. flat or decreasing slopes) had better academic achievement, and youth who experienced greater increases in NEM had worse academic achievement; in contrast, when parents closely monitored their children, changes in EC and NEM were only weakly associated with achievement. Overall, these findings demonstrate that temperament in late childhood, and changes in temperament across adolescence, have important prospective effects on academic achievement.

A guide for social science journal editors on easing into open science.

Journal editors have a large amount of power to advance open science in their respective fields by incentivising and mandating open policies and practices at their journals. The Data PASS Journal Editors Discussion Interface (JEDI, an online community for social science journal editors: www.dpjedi.org ) has collated several resources on embedding open science in journal editing ( www.dpjedi.org/resources ). However, it can be overwhelming as an editor new to open science practices to know where to start. For this reason, we created a guide for journal editors on how to get started with open science. The guide outlines steps that editors can take to implement open policies and practices within their journal, and goes through the what, why, how, and worries of each policy and practice. This manuscript introduces and summarizes the guide (full guide: https://doi.org/10.31219/osf.io/hstcx ).

Are trajectories of personality and socioeconomic factors prospectively associated with midlife cognitive function? Findings from a 12-year longitudinal study of Mexican-origin adults.

Problems with memory, executive function, and language are a significant public health concern, especially when they begin during midlife. However, there is relatively little work on risk and protective factors for cognitive function in middle adulthood. Using data from 883 Mexican-origin adults assessed up to 6 times across 12 years (Mage at Time 1 = 38.2 years; range = 27-63 years), the present study examined whether developmental trajectories (levels and slopes) of Big Five personality domains and socioeconomic factors (per capita income, economic stress) were prospectively associated with cognitive function (memory, mental status, verbal fluency) at the final assessment. We found that individuals with higher levels of, and smaller decreases in, Neuroticism had worse cognitive function 12 years later. Further, individuals with higher initial Conscientiousness had better subsequent memory, mental status, and verbal fluency, and individuals with higher Openness and Extraversion had better subsequent verbal fluency (but not memory or mental status). The trajectories of per capita income and economic stress were robustly associated with cognitive function, such that higher initial levels and greater increases in socioeconomic resources had protective associations, whereas higher levels and greater increases in economic stress had deleterious associations with cognitive function. Higher education level was associated with better cognitive function 12 years later. These findings suggest that changes in personality and socioeconomic factors across adulthood are associated with cognitive function, which may be informative for interventions to support healthier cognitive aging starting at least as early as midlife.

The development of personality-From metatraits to facets-Across adolescence and into adulthood in a sample of Mexican-origin youth.

The time between adolescence and adulthood is a transformative period of development. During these years, youth are exploring work, relationships, and worldviews while gaining the capacities needed to take on adult roles. These social and psychological processes are reflected in how personality develops across this period. Most youth personality development research has focused on the Big Five domains, ignoring the hierarchical structure of personality and missing broader, higher order processes and more specific, lower order processes. Toward a more comprehensive account, this study examines how personality develops from adolescence into the early years of adulthood at the metatrait (stability, plasticity), domain (Big Five), and facet levels. Data come from a longitudinal study of Mexican-origin youth (N = 645) with few socioeconomic resources who were assessed 5 times from Ages 14 to 23. We used latent growth curve models to investigate mean-level change, rank-order consistency, and the maintenance of trajectories for self-reported personality metatraits, domains, and facets. We found distinct developmental processes unfolding at each level of the hierarchy, including (a) mean-level changes in the metatraits and domains indicating increases in exploratory tendencies (i.e., plasticity) and maturity (i.e., increases in agreeableness and conscientiousness, decreases in neuroticism), and divergent change patterns between facets within each domain indicating nuanced maturational processes; (b) comparable levels of rank-order consistency for metatraits, domains, and facets; and (c) evidence that deviations from youth's developmental trajectories did not persist over time. Our findings offer insights into personality development that would be impossible to glean from the domain-level alone and adds needed sociocultural diversity to the literature.

The Development of Shyness from Late Childhood to Adolescence: A Longitudinal Study of Mexican-origin Youth.

Shyness, the tendency to be inhibited and uncomfortable in novel social situations, is a consequential personality trait, especially during adolescence. The present study examined the development of shyness from late childhood (age 10) through adolescence (age 16) using data from a large, longitudinal study of Mexican-origin youth (N = 674). Using both self- and mother-reports of shyness assessed via the Early Adolescent Temperament Questionnaire-Revised, we found moderate to high rank-order stabilities across two-year intervals and a mean-level decrease in shyness from age 10 to 16. Anxiety and depression were associated with higher initial levels of shyness, and anxiety was associated with greater decreases in shyness from age 10 to 16. Contrary to predictions, neither nativity (country of birth) nor language proficiency (English, Spanish) was associated with the development of shyness across adolescence. Thus, youth generally decline in shyness during adolescence, although there is substantial individual variability in shyness trajectories.

The role of temperament in the onset of suicidal ideation and behaviors across adolescence: Findings from a 10-year longitudinal study of Mexican-origin youth.

Suicide among young people is an increasingly prevalent and devastating public health crisis around the world. To reduce the rate of suicide, it is important to identify factors that can help us better predict suicidal ideation and behaviors. Adolescent temperament (effortful control, negative emotionality, positive emotionality) may be a source of risk and resilience for the onset of suicidal ideation, plans, and attempts. The present study uses longitudinal data from a large, community sample of Mexican-origin youth (N = 674), assessed annually from age 12 to 21, to examine how temperament is associated with the onset of suicidal ideation and behaviors during adolescence and young adulthood. Results indicate that higher levels of effortful control (activation control, inhibitory control, attention) are associated with decreased probability of experiencing the onset of suicidal ideation, plans, and attempts, whereas higher levels of negative emotionality (particularly aggression, frustration, and depressed mood) are associated with increased probability of experiencing the onset of suicidal ideation and behaviors. Positive emotionality (surgency, affiliation) was not associated with the onset of suicidal ideation and behaviors. Supplemental analyses showed conceptually similar findings for the Big Five, with Conscientiousness associated with decreased risk, Neuroticism associated with increased risk, and the other three dimensions showing largely null results. The findings did not vary significantly for boys and girls or for youth born in the U.S. versus Mexico. Overall, these findings suggest that adolescent temperament serves as both a protective factor (via effortful control/Conscientiousness) and a risk factor (via negative emotionality/Neuroticism) for suicidal ideation and behaviors in Mexican-origin youth.

The structure of adolescent temperament and associations with psychological functioning: A replication and extension of Snyder et al. (2015).

The present study attempts to replicate and extend Snyder et al. (2015, JPSP). The original study examined the latent factor structure of the Early Adolescent Temperament Questionnaire-Revised (EATQ-R), a commonly used measure of adolescent temperament, and showed that the resulting latent factors (i.e., effortful control, negative emotionality, and positive emotionality) had theoretically meaningful concurrent associations with several measures of adolescent functioning (depression, anxiety, attention-deficit hyperactivity disorder [ADHD], relational aggression, and school performance and behavior). We performed these same analyses using data from a large sample of Mexican-origin youth (N = 674), and also examined prospective associations between the three EATQ-R factors and measures of adolescent functioning assessed two years later. We found some evidence supporting the bifactor models reported in the original study but poor replication of the correlations among latent factors. Additionally, model comparisons demonstrated that correlated factors models produced more interpretable factors than the bifactor models. In contrast, we replicated most of the concurrent correlations (and extended the findings to prospective associations) between the EATQ-R factors and measures of adolescent functioning, supporting the construct validity of the EATQ-R as a measure of adolescent temperament. Thus, these findings raise concerns about the generalizability of the factor structure identified by Snyder et al. (2015), but bolster claims about the generalizability of the concurrent and predictive validity of the EATQ-R. Overall, differences between the present findings and those of Snyder et al. (2015) highlight the importance of ongoing construct validation in youth temperament research, especially with participants from groups traditionally underrepresented in psychological research.

The development of effortful control from late childhood to young adulthood.

The present study investigated the developmental precursors of effortful control, a temperament trait that involves the propensity to regulate one's impulses and behaviors, to motivate the self toward a goal when there are conflicting desires, and to focus and shift attention easily. Data came from the California Families Project, a multimethod longitudinal study of 674 Mexican-origin youth (and their parents), who were assessed at ages 10, 12, 14, 16, and 19. Effortful control (measured via self- and parent-reports) was moderately stable over time (r = .47 from age 10 to 19), and its developmental trajectory followed a u-shaped pattern (decreasing from age 10 to 14, before increasing from age 14 to 19). Findings from latent growth curve models showed that youth who experience more hostility from their parents, associate more with deviant peers, attend more violent schools, live in more violent neighborhoods, and experience more ethnic discrimination tend to exhibit an exacerbated dip in effortful control. In contrast, youth with parents who closely monitor their behavior and whereabouts exhibited a shallower dip in effortful control. Analyses of the facets of effortful control revealed important disparities in their trajectories; specifically inhibitory control showed linear increases, attention control showed linear decreases, and activation control showed the same u-shaped trajectory as overall effortful control. Moreover, most of the precursors of effortful control replicated for inhibitory control and attention control, but not for activation control. We discuss the broader implications of the findings for adolescent personality development and self-regulation. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

The role of effortful control in the development of ADHD, ODD, and CD symptoms.

Many adolescents have difficulty regulating their impulses and become prone to externalizing problems (e.g., attention-deficit/hyperactivity disorder [ADHD], oppositional defiant disorder [ODD], and conduct disorder [CD]) and other adverse consequences. Using multimethod data from a longitudinal study of Mexican-origin youth (N = 674), assessed annually from age 10 to 16, we examined the relations between effortful control and ADHD, ODD, and CD symptoms over time. Bivariate latent growth curve models showed negative correlations between the trajectories of effortful control and ADHD, ODD, and CD, indicating that steeper decreases in effortful control were related to steeper increases in ADHD, ODD, and CD symptoms. Using a novel statistical technique, the factor of curves model (FOCUS), we found that ADHD, ODD, and CD share a common "externalizing" trajectory during adolescence. Although effortful control was strongly associated with this common trajectory, it had few unique associations with the individual disorder trajectories, above and beyond their shared trajectory. When we extended the FOCUS model to include the effortful control trajectory as an indicator, we found that ADHD and ODD had strong loadings, whereas effortful control and CD had comparatively weak loadings on the shared developmental trajectory. Follow-up analyses showed that a two-factor solution, with externalizing symptom trajectories on one factor and the effortful control facet trajectories on a separate factor, was a better fit to the data than a one-factor solution. Finally, parent ASPD symptoms were related to increases in CD, but had no significant influence on effortful control, ADHD, or ODD. We discuss the implications for personality and externalizing problem development. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Reasonable Accommodations for Meeting the Unique Needs of Defendants with Intellectual Disability.

The Americans with Disabilities Act has allowed for greater participation of individuals with disabilities across a variety of contexts, most notably in employment settings. Individuals with intellectual disability (ID) are still precluded, however, from full participation in other contexts, and they are often relegated to the forensic arena without sufficient support, including after being adjudicated incompetent to stand trial (IST). Frequently, individuals who are adjudicated IST due to ID are committed to inpatient psychiatric hospitals that are unable to meet their unique needs. We argue that the provision requiring reasonable accommodations to secure meaningful participation in state-funded restoration efforts, explicitly covered by Title II of ADA, is both relevant and imperative for this group. Further, we argue that simple modifications to the forensic assessment process, as well as the trial itself, can provide the scaffolding to facilitate individuals' full and complete participation in the process, reducing the likelihood of an inappropriate determination as IST. In our opinion, failing to appropriately modify the forensic assessment, treatment, and trial process systematically excludes and uniquely disadvantages this population because individuals with ID are often able to meet the essential functions of participation except for interference from deficits commensurate with ID.
