Examining SEB skills' incremental validity over personality traits in predicting academic achievement.

Personality traits and social, emotional, and behavioral (SEB) skills share the same behavioral referents, but whereas traits refer to a person's typical or average performance, skills refer to their capacity or maximal performance. Given their shared behavioral foundations, an important question to address is whether personality traits and SEB skills independently predict important outcomes. In this study (N = 642), we examined whether subscales of the Behavioral, Emotional, and Social Skills Inventory (BESSI), a measure of SEB skills, provided incremental validity in the prediction of the ACT composite score, an important academic outcome for American adolescents, over the Big Five personality traits. Consistent with our expectations, on average, SEB skills showed stronger associations with ACT achievement scores than personality traits. Moreover, SEB skills added incremental validity over and above personality traits in predicting ACT achievement scores. The findings reinforce the importance of conceptually distinguishing and measuring traits and skills.

Multimethod Support for Using the Big Five Framework to Organize Social and Emotional Skills.

A challenge in the field of social and emotional learning is the lack of consensus regarding a framework to delineate key social and emotional skills (SE skills). Taking a conceptual approach, some have argued that the Big Five model from personality psychology offers a comprehensive framework to organize SE skills; however, little research has been done to empirically support this. In two studies-one using a factor analytic, data-driven approach, and one using an expert consensus approach-we provide multimethod evidence suggesting that there is a significant degree of overlap between SE skills and the Big Five, and we conclude that the Big Five can be used to organize SE skills.

Transcriptional features of biological age maintained in human cultured cardiac interstitial cells.

Ex vivo expansion of cells is necessary in regenerative medicine to generate large populations for therapeutic use. Adaptation to culture conditions prompt an increase in transcriptome diversity and decreased population heterogeneity in cKit+ cardiac interstitial cells (cCICs). The "transcriptional memory" influenced by cellular origin remained unexplored and is likely to differ between neonatal versus senescent input cells undergoing culture expansion. Transcriptional profiles derived from single cell RNASEQ platforms characterized human cCIC derived from neonatal and adult source tissue. Bioinformatic analysis revealed contrasting imprint of age influencing targets of 1) cell cycle, 2) senescence associated secretory phenotype (SASP), 3) RNA transport, and 4) ECM-receptor/fibrosis. A small subset of cCICs exist in a transcriptional continuum between "youthful" phenotype and the damaged microenvironment of LVAD tissue in which they were embedded. The connate transcriptional phenotypes offer fundamental biological insight and highlights cellular input as a consideration in culture expansion and adoptive transfer protocols.

Relating psychological and social factors to academic performance: A longitudinal investigation of high-poverty middle school students.

We investigated the relations between middle school students' psychological factors (academic commitment and emotional control), social perceptions (family involvement and school climate), and academic performance over time. Gender differences in these relations were also examined. Based on a two-year longitudinal data set of 942 middle-school students from a high-poverty district in the United States, we found that all four factors measured in 6th grade were predictive of GPA at the end of the 7th grade above and beyond gender, race, and home intellectual materials. Among these factors, emotional control had the strongest relation with GPA, and the importance of family involvement increased over time, especially for female students. The results also revealed the indirect effects of the social factors on GPA through the psychological factors, and mostly through emotional control. These findings highlight the complex relation between the social-emotional factors and academic outcomes in early adolescence.

Psychometric evaluation of the restructured clinical scales of the MMPI-2.

Conceptual overlap and heterogeneity have long been noted as weaknesses of the Minnesota Multiphasic Personality Inventory's clinical scales. Restructured clinical (RC) scales recently were developed to address these concerns (A. Tellegen et al., 2003). The authors evaluated the psychometric properties of the RC scales in psychology clinic clients (N=285) and military veterans (N=567). The RC scales were as internally consistent as the clinical scales and correlated strongly with their original counterparts (except for RC3/Hysteria). They also were less intercorrelated, produced conceptually clearer relations with measures of personality and psychopathology, and yielded somewhat greater incremental utility than the clinical scales. Thus, the RC scales demonstrated several psychometric strengths while utilizing 60% fewer items, but the 2 sets of scales cannot be used interchangeably. Interpretive considerations are discussed.

Match makers and deal breakers: analyses of assortative mating in newlywed couples.

We conducted a comprehensive analysis of assortative mating (i.e., the similarity between wives and husbands on a given characteristic) in a newlywed sample. These newlyweds showed (a) strong similarity in age, religiousness, and political orientation; (b) moderate similarity in education and verbal intelligence; (c) modest similarity in values; and (d) little similarity in matrix reasoning, self- and spouse-rated personality, emotional experience and expression, and attachment. Further analyses established that similarity was not simply due to background variables such as age and education and reflected initial assortment (i.e., similarity at the time of marriage) rather than convergence (i.e., increasing similarity with time). Finally, marital satisfaction primarily was a function of the rater's own traits and showed little relation to spousal similarity.

Dependency, impulsivity, and self-harm: traits hypothesized to underlie the association between cluster B personality and substance use disorders.

Cluster B personality disorders (PDs) (i.e., antisocial, borderline, histrionic, and narcissistic) typically show a high degree of comorbidity with substance use disorders (SUDs). Previous research suggests that the broad-based personality domains of Disinhibition and Negative Temperament/Neuroticism may be common factors to both types of disorders. Using a two-phase process (i.e., screening and follow-up), this study examined three lower-order personality traits (i.e., dependency, impulsivity, and self-harm) that fall within the Disinhibition and Neuroticism domains. The study evaluated the hypotheses that these traits (a) are related both to cluster B PDs and to SUDs; and (b) underlie the association between the two types of disorders. Results indicate that impulsivity and self-harm play a significant role in cluster B PDs and SUDs, as well as in their association with each other. However, dependency was not associated with either type of disorder. These results indicate that sets of individual traits can be of significant utility in understanding the comorbidity between PDs and SUDs.
