Measuring Epistemic Curiosity in Young Children

Epistemic curiosity (EC) is the desire to obtain new knowledge capable of either producing positive experiences of intellectual interest (I‐type) or of reducing undesirable conditions of informational deprivation (D‐type). Although researchers acknowledge that there are individual differences in young children's epistemic curiosity, there are no existing measures to assess the I‐ and D‐type constructs of EC in early childhood. The aim of this study was to develop and validate parent‐report scales that reliably assessed early expressions of I‐ and D‐ type EC in young children. To develop the I/D‐Young Children (I/D‐YC) scales, 16 potential items were administered to 316 parents of children aged 3 to 8. These items were adaptations of an existing adult self‐report measure of EC as well as newly developed items. Confirmatory factor analyses demonstrated that a 10‐item 2‐factor (5 I‐type, 5 D‐type) model had the best fit. Construct validity analyses and psychometric data indicated that our newly developed I/D‐YC scales are valid and reliable measures of individual differences in early expressions of I‐ and D‐type EC.

Examining gender differences in received,provided, and invisible social control: an application of the dual-effects model

The dual-effects model of social control not only assumes that social control leads to better health practices but also arouses psychological distress. However, findings are inconsistent. The present study advances the current literature by examining social control from a dyadic perspective in the context of smoking. In addition, the study examines whether control, continuous smoking abstinence, and affect are differentially related for men and women. Before and three weeks after a self-set quit attempt, we examined 106 smokers (77 men, mean age: 40.67, average number of cigarettes smoked per day: 16.59 [SD = 8.52, range = 1–40] at baseline and 5.27 [SD = 6.97, range = 0–40] at follow-up) and their nonsmoking heterosexual partners, assessing received and provided control, continuous abstinence, and affect. With regard to smoker's affective reactions, partner's provided control was related to an increase in positive and to a decrease in negative affect, but only for female smokers. Moreover, the greater the discrepancy between smoker received and partner's provided control was the more positive affect increased and the more negative affect decreased, but again only for female smokers. These findings demonstrate that female smokers' well-being was raised over time if they were not aware of the control attempts of their nonsmoking partners, indicating positive effects of invisible social control. This study's results emphasize the importance of applying a dyadic perspective and taking gender differences in the dual-effects model of social control into account.

Predicting Bystander Behavior to Prevent Sexual Assault on College Campuses: The Role of Self-Efficacy and Intent

Bystander intervention has been increasingly applied to prevent sexual violence on college campuses. Its underlying theory assumes unidirectional relationships between variables, predicting that bystander behaviors (i.e., actions taken to intervene in sexual violence situations) will be influenced by bystander intentions (BI; i.e., likelihood to intervene in the future), which in turn will be affected by bystander efficacy (BE; i.e., confidence to intervene). One question for theory is whether a reciprocal relationship exists between BI and BE. We used structural equation modeling (SEM) with longitudinal data to test unidirectional and reciprocal causal relations between BI and BE. Participants (n = 1390) were students at a northeastern US university. Four models were examined using SEM: (1) a baseline model with autoregressive paths; (2) a model with autoregressive effects and BI predicting future BE; (3) a model with autoregressive effects and BE predicting future BI; and, (4) a fully cross‐lagged model. Results indicated that reciprocal causality was found to occur between BI and BE. In addition, a final model demonstrated indirect effects of a bystander intervention program on bystander behaviors through both BI and BE at different time points. Implications for theory and practice are described, and directions for future research discussed.     

A depleted mind feels inefficacious: Ego‐depletion reduces self‐efficacy to exert further self‐control

Recent research has found that ego‐depletion undermines self‐control by motivating cognition that justifies conservation of mental resource. One potential cognitive mechanism is reduction of self‐efficacy. Specifically, we propose that ego‐depletion might demotivate self‐control by making people believe that they are inefficacious in exerting self‐control in subsequent tasks. Three experiments support the proposal. First, we demonstrated that (a) ego‐depletion can reduce self‐efficacy to exert further control (Experiments 1 to 3) and (b) the temporary reduction of self‐efficacy mediates the effect of depletion on self‐control performance (Experiment 2). Finally, we found that (c) these effects are only observed among participants who endorse a limited (versus non‐limited) theory of willpower and are, hence, more motivated to conserve mental resources (Experiment 3). Taken together, the present findings show that decrease in self‐efficacy to exert further self‐control is an important cognitive process that explains how ego‐depletion demotivates self‐control. This research also contributes to the recent discussion of the psychological processes underlying ego‐depletion.     

Envy mediates the relation between low academic self-esteem and hostile tendencies

In previous research, there has been little discussion about mediators or moderators that affect the negative relation between self-esteem and hostile tendencies. In the current article, we propose a model in which envy mediates that relation in the academic context. Across three studies, with correlational (N₁ = 303), experimental (N₂ = 76), and round-robin designs (N₃ = 330), results revealed that academic self-esteem indirectly influenced hostile tendencies through envy. In Studies 2 and 3, the indirect effect was moderated by the performance context. Results suggest that individuals with low academic self-esteem may exhibit hostile tendencies because of feelings of envy, especially in highly competitive contexts. Findings are discussed with respect to theoretical implications for research on personality and interpersonal perceptions.     

The General Factor of Personality: The “Big One,” a self-evaluative trait,or a methodological gnat that won’t go away?

Though recent research indicates that the Big Five can be subsumed under a “General Factor of Personality” (GFP), considerable dissention remains about whether the GFP is a substantive trait (either a “mega”-trait or simply, positive self-evaluation), or a response artifact. To disentangle these potential explanations, we estimated GFP saturation based on scales within a single inventory (which may share response artifacts) versus between different inventories (wherein the GFP would be more substantive). Drawing on meta-analytic findings across 370 independent samples of 155,781 individuals, GFP saturation was reduced substantially when based on between inventory data (26%) compared to within inventory data (50%). These results indicate that the GFP functions as a response artifact that may be reduced by administering scales from different inventories. However, some GFP variance also appears to represent stable tendencies that span across inventories. Overall, the GFP appears to be partly a stable, self-evaluative trait and partly a set of response tendencies specific to a particular personality inventory. We discuss the implications of these results for academic and applied personality measurement.     

Personality and physical activity: A systematic review and meta-analysis

Whether personality determines physical activity or its outcomes is relevant for theory and public health but has been understudied. We estimated the population correlations between Big-Five personality factors and physical activity and examined whether they varied according to sample characteristics and study features. Database searches were conducted according to PRISMA guidelines, for articles published in the English language prior to November 1st, 2013. Sixty-four studies including a total of 88,400 participants yielded effects (k) for Extraversion (88), Neuroticism (82), Conscientiousness (69), Openness (51) and Agreeableness (52). Significant mean r was found for Extraversion (r = .1076), Neuroticism (r = −.0710), Conscientiousness (r = .1037) and Openness (r = .0344), but not Agreeableness (r = .0020). Effects were moderately heterogeneous (I² range = 44–65%) and varied by sample characteristics (e.g., age, gender, or clinical status) and/or study features (e.g., measure quality or item format). This analysis expands results of previous reviews and provides new support for a relationship between physical activity and Openness. Future studies should use better measures of physical activity and prospective designs, adjust for statistical artifacts, and consider advances in the conceptualization of personality.     

Structural validity of the Mental Health Continuum-Short Form: The bifactor model of emotional,social and psychological well-being

The Mental Health Continuum-Short Form (MHC-SF) is a growingly popular questionnaire designed to assess three components of well-being: emotional, social, and psychological. The main goal of the present study was to evaluate the structural validity of the MHC-SF and test the bifactor model of the MHC-SF, which includes one general factor and three specific factors of well-being. Sample 1 consisted of 1095 Serbian students (aged 18–26 years), while Sample 2 included 325 Serbian adults (aged 27–63 years). The bifactor model of the MHC-SF yielded the best fit to the data across the two samples. The results showed that the general factor of well-being accounted for substantially greater amount of variance of the MHC-SF than three specific factors of well-being. After controlling for the general factor, three specific factors explained a small portion of variance in well-being. In addition, the three subscales of the MHC-SF showed low reliability as estimated by omega-subscale coefficients, indicating that these subscales comprise too small amount of reliable variance to interpret. The present findings suggest that researchers should not calculate separate scores for three types of well-being when using the MHC-SF and that alternative measures of specific components of well-being should be considered.
