A hierarchical investigation of personality and behavior: Examining Neo-Socioanalytic models of health-related outcomes

Based on proposed hierarchical relations derived from the Neo-Socioanalytic Theory of personality [Roberts, B. W., & Wood, D. (2006). Personality development in the context of the Neo-Socioanalytic Model of personality. In D. K. Mroczek & T. D. Little (Eds.), Handbook of personality development (pp. 11–39). Mahwah, NJ: Lawrence Erlbaum Associates Publishers], the present study examined the relationships between trait and motivation constructs and health-related outcomes. Participants (N = 201) completed a Big Five measure of personality traits, parallel exercise and diet behavioral identity trait measures, measures of personal values, exercise and diet-related personal strivings, and exercise and diet self-reports. Participants also completed a physical activity assessment and were weighed on a calibrated electronic scale from which body fat percentage could be determined. It was expected that contextualized trait and motivation constructs would mediate the relations between broad trait and motivation constructs and the health-related outcomes. The patterns of relations across trait and motivation constructs also were explored. The trait domain exhibited the expected pattern of hierarchical relations, but the motivation domain showed a more complex pattern of relations. The results are discussed in relation to a hierarchical model of personality and behavior that brings together trait and motivation constructs at multiple levels of analysis.     

Mood-congruent thoughts and personality disorder pathology

The primary aim of this research was to investigate associations that depression severity and trait anxiety have with reactions to specific, identifiable thoughts experienced by persons with varying levels of personality disorder (PD) pathology as they went about their day-to-day lives. Ninety-eight psychotropic medication-free persons participated in an experience sampling assessment procedure over four consecutive days, during which participants recorded specific thoughts experienced moments before a page signal was received and corresponding ratings of thought discomfort. Thought discomfort, regarded as an emotional reaction to thoughts or their evaluation, was moderately associated with several forms of PD pathology, particularly Cluster C pathology. Once depression severity and trait anxiety were controlled, however, associations between PD pathology and thought discomfort were eliminated. Findings from this research generally support the mood-congruence of negatively valenced thoughts in relation to PD pathology.     

Personality in middle childhood: A hierarchical structure and longitudinal connections with personality in late adolescence

Research on the structure of personality in middle childhood, while advancing, is still in the early stages of development. In this study, we employed a group of 1563 twins to elucidate the hierarchical structure of personality in middle childhood and provide connections to established personality traits in adult populations. Our results provide evidence for a higher-order structure of personality in middle childhood that maps on to recent findings in adult populations supporting hierarchical relationships among 2-, 3-, 4-, and 5-factor models of personality. In addition, primary higher-order personality traits rated by parents at age 11 showed substantial predictive validity for analogous traits rated by self at age 17. We discuss our results within the context of developing a convergent hierarchical taxonomy of personality in middle childhood and the importance of multi-informant investigations.     

Uniqueness of real-valued hierarchical classes models

Two novel uniqueness theorems are derived for the family of hierarchical classes (HICLAS) models, a family of structural decomposition models for N-way N-mode data that imply simultaneous hierarchically organized classifications of all modes involved in the data. The theorems generalize earlier results on binary HICLAS models to the integer- and real-valued cases. In addition, they allow for a shorter and insightful proof of a result on Boolean matrix invertibility that goes back to earlier work of Luce (1952) and Rutherford (1963).     

The personality traits of liked people

There is surprisingly little understanding of how personality traits are associated with being generally liked by others after adolescence (Ozer & Benet-Martinez, 2006). We examined the relationship between self-reported personality traits and being generally liked in young adulthood in Greek organizations and freshman dormitories. We found a high level of consistency in which traits were associated with being liked. We examined the relationship between liked and socially desirable traits, using a recent theory on agency and communion (Wojciszke, Abele, & Baryla, 2009). Results help to create a personality profile of the person who is more liked by others, especially pointing to the importance of communal characteristics that are associated with behavior benefiting others.     

The joint structure of maladaptive personality traits and psychopathology

We examined the joint structure of symptoms/syndromes of psychopathology (MMPI-2 Restructured-Clinical Scales; MMPI-2-RC; Tellegen et al., 2003) and maladaptive personality traits (Schedule for Nonadaptive and Adaptive Personality; SNAP-2; Clark, Simms, Wu, & Casillas, 2014) via a series of top-down factor analyses—Goldberg (2006) “bass-ackwards approach”—in a sample of 419 mental-health outpatients and 567 military veterans. A three-factor solution consisting of Negative Affectivity (including Oddity), Low Positive Affectivity, and Disinhibition-versus-Constraint best represented the joint symptom-trait structure, consistent with the third level of Markon et al. (2005) joint hierarchical structure of normal and maladaptive personality traits. Our results point to robustness of the structure of adaptive and maladaptive personality traits and symptoms of psychopathology at the three-factor level.     

From personal goals disclosed to personality judgments composed: Trait perceptions made on the basis of idiographic goals

Traits and goals represent discrete units of personality. Here, we examined the consensus, validity, and cues of trait judgments made on the basis of targets’ goals. Targets (N = 409) generated lists of personal goals and rated their traits. Observers were provided with targets’ (a) lists of goals, (b) first goals, or (c) fifth goals, and then reported trait judgments of targets. Perceptions of targets, which were formed on the basis of the emotional content of goals, were largely consistent among observers. Furthermore, observer reports made on the basis of participants’ lists of goals converged with self-reports of all traits whereas reports made on the basis of single goals converged with self-reports of certain (e.g., extraversion), but not all, traits.     

Gender differences in implicit and explicit personality traits

This article investigates gender differences in implicit and explicit measures of the Big Five traits of personality. In a high-powered study (N = 14,348), we replicated previous research showing that women report higher levels of Agreeableness, Conscientiousness, Extraversion and Neuroticism. For implicit measures, gender differences were much smaller for all, and opposite in sign for Extraversion. Somewhat higher levels of implicit Neuroticism and Agreeableness were observed in women, and somewhat higher levels of implicit Extraversion and Openness were observed in men. There was no gender difference in implicit Conscientiousness. A possible explanation is that explicit self-concepts partly reflect social norms and self-expectations about gender roles, while implicit self-concepts may mostly reflect self-related experiences.     

The five factor model of personality and alexithymia: A meta-analysis

The main objective of the study was to examine the relationship between the Five Factor Model of Personality and alexithymia. Data were collected from 25 studies, which included 30 independent samples, 1384 effect sizes, and 7440 participants. All analyses were conducted with random effects models. Greater neuroticism and lower extraversion, openness to experience, agreeableness, and conscientiousness were associated with higher cognitive alexithymia. Greater neuroticism and openness to experience were linked to lower affective alexithymia. Additionally, age moderated the relationship between the Five Factor Model of Personality and cognitive alexithymia, in that the association between neuroticism and alexithymia became stronger with age whereas the relations of extraversion, openness to experience, agreeableness, and conscientiousness with alexithymia became weaker with age.     

Impulsivity mediates the association between borderline personality pathology and body mass index

Borderline personality disorder (BPD) is associated with obesity, a major risk factor for a number of chronic illnesses (e.g., cardiovascular disease). We examined whether impulsivity and affective instability mediate the association between BPD pathology and body mass index (BMI). Participants were a community sample of adults ages 55–64 and their informants. The Structured Interview for DSM-IV Personality measured BPD symptoms and the Revised NEO Personality Inventory measured self- and informant-report impulsivity and affective instability. Mediation analyses demonstrated that only higher self-report impulsivity significantly mediated the association between greater BPD pathology and higher BMI. A subsequent model revealed that higher scores on the impulsiveness (lack of inhibitory control) and deliberation (planning) facets of impulsivity mediated the BPD–BMI association, with impulsiveness exerting a stronger mediation effect than deliberation. Obesity interventions that improve inhibitory control may be most effective for individuals with BPD pathology.     

Within- and between individual variability of personality characteristics and physical exercise

Using two independent samples, the study investigated links of within- and between-individual variability in personality states in three personality domains—Neuroticism, Extraversion, and Conscientiousness—with physical activity. Activity was defined as self-reported quantity of exercising or walking/cycling. More physical activity was associated with people reporting higher levels of Extraversion and Conscientiousness than they usually did, with the associations clearly replicating across samples and generalizing to all items of these domains. This pattern tended to reflect associations at the level of between-individual differences. When the three domains simultaneously predicted activity, within-individual variance in Neuroticism also emerged as a positive predictor, whereas between-individual level associations waned. The findings are consistent with within-individual differences in personality ratings reflecting meaningful, context-relevant variability.     

Physical activity and personality: A behaviour genetic analysis

ObjectivesThe aim of this study was to obtain a heritability estimate of exercise behaviour in twins and to examine the genetic and environmental contributions to phenotypic associations between personality and exercise behaviour.DesignTwin study was used, the sample including 339 twin pairs (105 MZ and 234 DZ), between 15 and 22 years of age (M = 18.6, SD = 2.31).MethodThe participants filled in a NEO-FFI personality inventory and answered two questions about the frequency (FPE) and intensity (IPE) of physical exercise. We also calculated the composite physical exercise score (CS) representing a combination of FPE and IPE items.ResultsThe broad heritability estimates of three physical exercise variables (FPE, IPE, CS) were significant, with results in the 0.55 to 0.69 range. We found significant phenotypic associations with neuroticism and extraversion. Contrary to our expectations, correlations with conscientiousness were not significant. People scoring higher on extraversion and lower on neuroticism reported exercising more often and more intensely. Phenotypic association between personality traits and physical exercise variables were due to overlapping genetic influences.ConclusionsOur results indicate that the genetic factors contributing to an active lifestyle overlap with those contributing to personality traits extraversion and neuroticism, in line with the “nature” hypothesis which infers the presence of biological differences in predisposition for regular physical activity.     

If it walks like a duck: Construct validation of proverb-based personality dimensions

Previous research has investigated the personality-relevance of proverb endorsement. In this previous research, however, participants were provided with additional information to aid them in their interpretations of the proverbial phrases. Although seven proverb-based personality dimensions were revealed, it is not entirely clear whether these dimensions truly reflect dimensions encoded in the proverb domain itself, or whether they reflect, instead, meanings imposed by the definitional context. In this study, college-student participants relied on their own interpretations of proverbial wisdom to guide their endorsements. Significantly, two of the previously reported dimensions - the two that had previously seemed to be the most novel - did not replicate. Five proverb-based dimensions were replicated, however, and the relationships between these dimensions and dimensions assessed by more established personality inventories were explored. This study thus confirms that proverbial wisdom does indeed advocate behavior and beliefs relevant to important dimensions of individual difference.     

Inside the happy personality: Personality states,situation experience,and state affect mediate the relation between personality and affect

Personality traits are strongly related to affect, but the mechanisms accounting for this association remain mostly unclear. We test a new theoretical model that proposes that personality states, situation characteristics, and affective states mediate the relation between personality traits and trait affect. Data from an experience sampling study (N = 206; 4381 observations) indicate that personality traits are associated with personality states and experienced situation characteristics, personality states and experienced situation characteristics are associated with state affect, state affect is associated with trait affect, and that these variables indeed mediate the relation between personality traits and trait affect. These results emphasize the importance of daily experiences for trait-level variables and call for further research on the interplay between personality, behavior, situations, and affect.     

The relationship between personality traits and psychotic like experiences in a large non-clinical adolescent sample

ObjectiveThe relationship between personality and psychosis is well established. It has been suggested that this relationship may be partly accounted for by higher levels of depression in individuals with certain personality traits. We explored whether the link between personality and psychotic symptoms is already apparent in adolescence, and if this association would still hold when depression was controlled for.Method654 secondary school students were surveyed via self-report questionnaires measuring the Five-Factor model of personality (NEO-FFI), depression (CES-D) and psychotic-like experiences (CAPE).ResultsPositive associations were found between Neuroticism and all CAPE-subscales except Magical Thinking, which was in turn associated with all other personality traits when at high levels. Agreeableness was negatively associated with all CAPE-subscales, while Openness to Experience was only positively associated with Persecutory Ideas and Magical Thinking. After controlling for depression, many of the significant associations remained.ConclusionOur findings suggest that the chance of having psychotic like experiences is more likely for adolescents with certain personality traits. These associations are not fully explained by depression, especially when psychotic experiences are at higher levels. Future research is needed to investigate if these personality traits might put a person at risk for the development of full-blown psychosis.     

Similarity between partners in real and perceived personality traits as measured by the Myers-Briggs type indicator

From 90 couples, 90 male and 90 female subjects, two sets of scores on the four personality dimensions measured by the Myers-Briggs Type Indicator (MBTI) were obtained by letting each person answer each item twice, first in the ordinary way and then as he or she believed the partner would answer the item. Correlations between partners' self-reported scores were all close to zero, whereas the correlations between the partner-reported scores and the self-reported scores were high for both males and females and for all the four dimensions measured by the MBTI, thus indicating that partners were not similar in personality traits, but they had a realistic perception of each other. The results support the hypothesis that mating is random in terms of personality traits.     

Compulsive buying and the Five Factor Model of personality: A facet analysis

In recent years, the broad dimensions of the Five-Factor Model have been an object of an increasing interest in the compulsive buying field. Nevertheless, the absence of studies that analyse the FFM facets in compulsive buyers is surprising. This study, employing the NEO-PI-R, intends to assess whether there are differences in both facets and broad traits, in three groups with low (n = 792), moderate (n = 456), and high (n = 117) compulsive buying propensities. The results confirm that the high propensity group presents the highest significant levels in neuroticism and the lowest in conscientiousness and agreeableness. Whereas all neuroticism and conscientiousness’ facets establish significant differences among the groups (the largest correspond to anxiety and impulsivity, and dutifulness and self-discipline, respectively), only some significant differences for agreeableness are established (namely, straightforwardness, altruism, trust, and modesty). Finally, even though there are no differences between groups in extraversion and openness factors, extraversion’s excitement-seeking, positive emotions and assertiveness facets, and openness’ aesthetics and ideas facets do establish significant differences. Generally speaking, these findings advocate the need to analyse facets, in addition to the broad factors, in the effort to advance our understanding about the elements that make up the personality structure of the compulsive buyer.     

I need my smartphone: A hierarchical model of personality and cell-phone addiction

Using a comprehensive personality model, this study is the first to examine the relationship between a full range of personality traits and cell phone addiction. 346 college students completed an online survey that asked respondents to complete measures of the Big-Five personality traits and measures of materialism and need for arousal, Barratt’s (1959) impulsiveness scale, and a four-item measure of cell phone addiction. Data were analyzed using structural equation modeling. Couched in Mowen’s (2000) 3M Hierarchical Model of Personality, the elemental traits of emotional instability and materialism were positively associated while introversion was negatively associated with cell phone addiction. The central trait of attention impulsiveness exhibited a direct and positive association with cell phone addiction. A significant negative relationship between conscientiousness and all three dimensions of Barratt’s impulsiveness scale (central trait) was found. Several additional relationships between the elemental traits of Mowen’s personality hierarchy and the three dimensions of impulsiveness (central trait) also were uncovered. Study implications and future research directions are discussed.
