The current research examined the effects of the cost of sharing information and individual levels of agreeableness on participants' willingness to help out-of-the-loop individuals. In this study, 119 students from undergraduate psychology courses played the role of a CEO of a pharmaceutical company with three regional managers under their supervision. The participants were given the opportunity to give any number of facts to both in-the-loop managers and the single out-of-the-loop manager. Participants in the high-cost condition were informed that they would be required to spend an additional 2 minutes in the lab explaining the usefulness of the facts distributed for every fact they gave a general manager. Participants in the low-cost condition were told they would be required to spend an additional 10 seconds for each fact they gave a regional manager. After distributing facts among the three regional managers under their supervision, the participants were asked to complete an agreeableness scale, a conscientiousness scale, a needs assessment, and a demographics questionnaire. The results indicated that only the amount of time it would cost an individual to share facts dictated how many facts they would share. The results also found that neither condition nor individual level of agreeableness significantly influenced the difference between the number of facts individuals gave to out-of-the-loop individuals versus in-the-loop individuals.

Past research demonstrates the high prevalence of occupational accidents and injuries, and therefore much work has gone into examining potential antecedents to such incidences. However, while some research has examined personality as a potential antecedent, results suggesting personality as a significant predictor of occupational safety remain inconclusive. Therefore, the purpose of the current work is to conduct a cross-sectional multi-source survey study that will take a closer look at the relationships between various personality variables and occupational safety. Essentially, the purpose of the current study is threefold: (1) to examine the relationships between two Big Five personality factors, safety locus of control, and optimism bias as antecedents of safety performance and outcomes, (2) to take a facet-level analysis by breaking up the extraversion and conscientiousness factors into their constituent facets in order to see if each facet may be differentially related to occupational safety when compared the overall factor, and (3) to examine various moderators that may affect the relationships between extraversion and occupational safety. Results of this study suggest that the extraversion and conscientiousness facets are not differentially related to occupational safety. Further, some evidence for contextual moderators in the relationships between personality and safety performance was found. Overall, this study provides further insight into the role that personality may play in predicting safety across various industries.

An abundance of literature has shown the five-factor model personality traits can influence current and lifetime substance use. Life satisfaction, although less clearly, has also demonstrated a significant contribution to substance use behaviors and outcomes. Still, little is known about how life satisfaction influences the relationship between personality and substance use measures pertinent to recovery like drug use refusal self-efficacy. The goal of this study is to advance the current literature on substance use by examining the mechanisms influencing the relationship between personality and life satisfaction and drug use refusal self-efficacy for a sample diagnosed with at least one substance use disorder (SUD) and/or alcohol use disorder (AUD). Data was analyzed using deidentified information from a large diverse SUD client pool (n = 348) who were recruited from the general population and from two Midwest SUD treatment centers for a larger parent study. A series of mediation and moderation analyses were tested. The relationships between both neuroticism and conscientiousness with drug use refusal self-efficacy were significantly mediated by life satisfaction. Life satisfaction significantly moderated the relationship between extraversion and drug use refusal self-efficacy. These findings suggest life satisfaction may be a novel modifiable treatment target to reduce negative effects of personality on SUD drug refusal self-efficacy, and that life satisfaction may influence and change how extraversion relates to risks among those in recovery. / M.S. / Substance misuse costs the United States healthcare system billions each year, but substance use disorder treatment reduces these costs. Unfortunately, only a small percentage of individuals seek treatment in part because it is notoriously difficult, and relapses are common. Factors like personality traits and life satisfaction influence current and lifetime substance use. The goal of this study was to advance the current literature on substance use by examining the mechanisms influencing the relationship between personality and life satisfaction and the ability for an individual to refuse drugs or alcohol (drug use refusal self-efficacy). Data was analyzed using information from a large diverse substance use disorder client pool (n = 348) who were recruited from the general population from two Midwest treatment centers. A series of mediation and moderation analyses were tested. Life satisfaction influenced the relationships between both neuroticism and conscientiousness with drug use refusal self-efficacy. The relationship between extraversion and drug use refusal self-efficacy differed based on the individual’s life satisfaction. These findings suggest modifying life satisfaction may reduce negative effects of personality on drug refusal self-efficacy, and that life satisfaction may influence and change how extraversion relates to risks among those in recovery.

Studien syftade till att undersöka om det finns samband mellan conscientiousness, Locus of Control och arbetsmotivation samt om ålder och anställningslängd predicerar en del av ar-betsmotivation. Studien omfattade 63 anställda (28 kvinnor och 35 män) på ett telekommuni-kationsföretag i Sverige. För att studera conscientiousness användes ett egenformulerat test med god intern homogenitet, Cronbachs alfa = 0,85. För att mäta Locus of Control och ar-betsmotivation användes redan konstruerade test med god validitet och reliabilitet, skapade av Rotter (1966) och Cammann, Fichman, Jenkins och Klesh (i Bowling & Hammond 2008). I den statistiska prövningen användes både bivariat korrelation i form av Spearmans rho och MRA-standard och hierarkisk. Spearmans rho visade ett signifikant samband mellan consci-entiousness och arbetspsykologisk motivation. Standard MRA visar att endast conscientious-ness förklarar en del av arbetspsykologisk motivation. Varken ålder eller anställningslängd predicerade delar av arbetspsykologisk motivation, vilket inte stämmer överens med tidigare forskning. I diskussionen förs resonemang om resultatet i relation till tidigare forskning. / The study aimed to investigate whether there are correlations between conscientiousness, Lo-cus of Control and job motivation, and if age and length of service predict job motivation. The study comprised 63 staff (28 women and 35 men) at a telecommunications company in Swe-den. To study conscientiousness, we used a self-constructed test with good internal homo-geneity, Cronbach's alpha = .85. To study Locus of Control and job motivation we used al-ready developed tests, with high validity and reliability, created by Rotter (1966) and Cam-mann, Fichman, Jenkins and Klesh ( in Bowling & Hammond 2008). Statistical tests, using both bivariate correlations such as Spearman's rho and standard and hierarchical MRA showed significant relationship between conscientiousness and job motivation. Using stan-dard MRA shows that only conscientiousness predicts aspects of motivation. Neither age nor length of service predicted aspects of motivation, which is not consistent with previous re-search. The discussion is carried on effect on the outcome in relation to previous research.

To better understand the cognitive processes associated with faking behaviors, Ajzen?s Theory of Planned Behavior was adapted to the study of faking on overt integrity tests. This decision-based model is then expanded through the inclusion of a key outcome (counterproductive work behavior) and basic individual differences (conscientious personality and cognitive ability). Results from two student samples (n = 233 and n = 160) demonstrate that conscientiousness negatively predicts attitudes toward faking on employment tests, while cognitive ability predicts the ability to fake. In turn, faking ability moderates the effect of self-reported faking motive on actual test scores, while self-reported faking decreases the validity of integrity tests for predicting counterproductive work behaviors. Implications are discussed.

Conscientiousness-related personality traits are relevant predictors of many outcomes in achievement domains outside sport. They have also been associated with several outcomes in sport, however, their relative role on athletes’ deliberate practice (DP) and other criteria of expertise development has not been investigated. The overall aim of this dissertation was to examine the role of conscientiousness-related traits on sport expertise development. It had six specific purposes: (a) to examine the structural validity of conscientiousness-related measures; (b) to understand whether athletes’ DP amounts, skill level, and other criteria of expertise development could be predicted by these measures; (c) to identify the best personality predictor and combination of predictors that explained the maximal variance in different criteria of expertise development; (d) to examine whether grit facets predicted athletes’ practice engagement across a demanding sport season; (e) to explore coaches’ perspectives on the behavioural indicators of conscientious, gritty, and self-controlled athletes in training; and (f) to explore coaches’ views about how these personality traits may impact athletes’ quantity and quality of practice and development toward higher skill levels. The dissertation used a sequential explanatory mixed-methods design, wherein Phase 1 (Articles 1, 2, and 3) quantitatively pursued purposes (a) to (c), Phase 2 (Article 4) addressed (d), and Phase 3 (Article 5) qualitatively addressed (e) and (f). Article 1 tested the factor structure of the Brief Self-Control Scale in sport and showed distinct associations between self-control variables and (a) sport-specific practice amounts, (b) engagement in various practice contexts, and (c) threats to commitment to one’s sport, in a diverse sport sample. Article 2 conducted factor analyses of the Grit Scale in sport and examined a full latent variable model showing associations between grit variables and several criteria of expertise development. In particular, perseverance of effort associated with athletes’ weekly amounts of DP, engagement in different practice contexts, and skill level, while consistency of interests associated with athletes’ commitment to their sport. Article 3 comprised two studies. In Study 1, path analyses were used to assess the role of conscientiousness on criteria of expertise development. At the broad level, conscientiousness predicted athletes’ engagement in practice contexts and commitment to their sport; at the facet-level, achievement-striving was the best predictor of athletes’ weekly DP and engagement in practice contexts. The systematic test of the role of self-control (Article 1), grit (Article 2), and conscientiousness (Article 3, Study1) for key criteria of expertise development culminated with Study 2 of Article 3, which reported comparative analyses of the predictive ability of self-control, grit, and conscientiousness facets—which had shown to be significant predictors when assessed separately—for the criterion measures of sport expertise. Study 2 showed that (a) perseverance of effort was the best predictor of athletes’ weekly DP, engagement in mandatory practice, and the only predictor of higher skill level, (b) achievement-striving best predicted athletes’ engagement in optional practice, and (c) consistency of interests best predicted athletes’ commitment to their sport. Article 4 tested whether athletes’ self-reported levels of grit (broad and facets) were longitudinally associated with their coach-reported practice engagement throughout one sport season. Perseverance of effort was the grit variable most related to indicators of practice engagement, the only variable related to overall practice engagement across three time points, and the only variable marginally associated with athletes’ stability of practice engagement over time. Article 5 explored coaches’ views about the behavioural indicators of athletes’ conscientiousness, grit, and self-control in the daily training environment and how these traits impacted athletes’ training and development. Coaches described (a) conscientious athletes as systematic and detail-oriented, highly considerate of others, and highly engaged in self-regulation; (b) gritty athletes as those who persevere despite adversity and work hard in practice; and (c) self-controlled athletes as those who control impulses, resist temptations, and delay gratification. Coaches believe grit, conscientiousness, and self-control play important roles on athletes’ development toward higher skill levels, but results generally highlighted the preponderance of perseverance of effort. Potential mechanisms (e.g., conscientiousness—self-regulation—practice quality and conscientiousness—self-regulation—skill level) were highlighted to help explain the personality-expertise link found in Phases 1 and 2. This dissertation contributed to the literature on sport expertise by parsimoniously identifying conscientiousness-related personality traits that were associated with measures of athletes’ practice quantity, quality, and stability, commitment to sport, and higher skill level. Although several facets (i.e., perseverance of effort, consistency of interests, achievement-striving, self-discipline, and dutifulness) showed associations with practice and performance-related outcomes, this dissertation generally highlighted the role of grit facets. In particular, while perseverance of effort was the best predictor of athletes’ amounts of DP, the only grit variable associated with quality practice engagement over time, and the only predictor of higher skill level, consistency of interests was the best predictor of commitment variables. Furthermore, results based on coaches’ descriptions (a) provided behavioural indicators of conscientiousness-related traits that serve as reference points for practitioners aiming to help athletes develop desirable traits, (b) suggested that gritty athletes ‘work hard’ and conscientious athletes ‘work smart’, and (c) proposed mechanisms to explain the personality-expertise link found in the quantitative studies. Taken together, the results of this dissertation suggest that the tendency to persevere despite adversity and mindfully use self-regulated processes seems to be a powerful predisposition for athletes’ development toward expert levels of performance.
