The relationship between temperament and personality: An exploratory study

Although the terms temperament and personality are often used interchangeably in the literature and clearly are conceptually related, there is little empirical data to illuminate their relationship. In this exploratory study we measured temperament (using the Dimensions of Temperament Survey), and personality (using the Eysenck Personality Questionnaire), in young adolescents and in adults. Some age and sex differences in relationships between the measures and their correlations were found. The temperament dimension of adaptability was clearly related to Eysenck's Extraversion factor and reactivity to Neuroticism in females. More substantial relationships emerged in the adult sample than in the adolescent group, Our data, combined with that of a 1984 Australian study using different techniques, provides substantial support for measurable overlap between some dimensions of temperament derived largely from the developmental literature, and Eysenck's personality theory.     

Biochemical correlates of personality traits in normals: An exploratory study

This study attempted to identify biochemical systems associated with the personality dimensions of Extraversion (E), Neuroticism (N), Psychoticism (P), Sensation Seeking (SS) and Impulsivity (Imp). The subjects were 43 normal volunteers who volunteered to take a battery of psychological tests and allow investigators to obtain samples of blood, urine and cerebrospinal fluid (CSF) for biochemical assessment.Substantial positive correlations were found between CSF norepinephrine (NE), MHPG (the principal metabolite of NE), DBH (an enzyme involved in the production of NE) and plasma MHPG and DBH; all of these are regarded, in some part, as putative indicators of central noradrenergic activity. After partialling out the influences of age, height and weight, a number of significant relationships were found between psychological traits and biochemical variables. Extraversion correlated positively and introversion and neuroticism correlated negatively with CSF Ca. Neuroticism also correlated negatively with plasma MHPG. Ego Strength (inversely related to Neurotic Introversion), P and Disinhibitory SS correlated negatively with CSF cort. General SS correlated negatively with CSF NE and plasma DBH, and these correlations were significant in both males and females, as well as in the total group. The results are consistent with some biological models of personality, but suggest the need for modification in others.     

Pathological personality facets and emotion (dys)regulation in gambling disorder

A number of researches showed high prevalence of personality disorders among addicted gamblers. However, there are still few studies investigating the role of pathological personality facets in Gambling Disorder (GD). Moreover, the nature of the relationship between GD and pathological personality is not clear. We administered to a group of addicted gamblers (N = 79) and a group of healthy participants (N = 101) a battery of self-report questionnaires encompassing the South Oaks Gambling Screen (SOGS), The Personality Inventory for DSM-V (PID-5), the Difficulties in Emotion Regulation Scale (DERS) and the Emotion Regulation Questionnaire (ERQ). Analyses of variance showed that addicted gamblers, compared to healthy participants, scored higher on most of the subscales of the DERS, on the Suppression Dimension of the ERQ and on the five main domains of the PID-5 whereas they obtained lower scores on the Reappraisal subscale of the ERQ. Moreover, multiple regression analyses indicated that some specific facets of pathological personality, emotion dysregulation and lack of cognitive reappraisal, significantly predict GD's severity. Finally, emotion dysregulation levels and lack of cognitive reappraisal partially mediated the relationship between these and GD's severity. Our results confirmed the central roles played by both pathological personality and deficit in emotion regulation capacities in GD. Specifically, Impulsivity, Lack of Perseverance and Suspiciousness may be important predictors of GD severity. Moreover, emotion dysregulation and lack of adaptive emotion regulation strategies partially explained such relationship. As such, training for emotion regulation abilities appears strategically useful in the treatment of addicted gamblers with pathological personality traits.     

Image of God and personality pathology: An exploratory study among psychiatric patients

The associations between personality pathology according to DSM-IV, symptomatology and God image were examined among a group of 46 psychiatric patients. Features of personality disorders were assessed using the 'Questionnaire to Assess Personality Pathology', a self-report screener. God image was measured by means of the 'Questionnaire God Image'. Symptomatology was assesed by means of the SCL-90. The more personality pathology present, the more negative the image of God. The negative image of God appeared to be associated with personality pathology, in particular with pathology from the DSM-IV A- and C-cluster, even after controlling for the influence of symptomatology, suggesting that the association between symptomatology and the God image is mediated by personality pathology. When symptoms of the A-cluster are present God is experienced as detached and passive. When C-cluster symptoms prevail, God is experienced as a harsh judge. Results are discussed both from a psychodynamic object-relational as well as from a cognitive schema focused perspective.     

Factor structure of the Dysfunctional Attitude Scale (Form A) and the Automatic Thoughts Questionnaire: an exploratory study

The factor structure of the Norwegian version of the Dysfunctional Attitude Scale and the Automatic Thoughts Questionnaire was investigated with a sample of 344 male military recruits. Principal factor analyses with promax rotation indicated four factors for the former, labeled Performance Evaluation, Need for Approval, Autonomous Attitude, and Perfectionism which accounted for 15.5%, 3.6%, 2.6%, and 2.5% of the total variance, respectively. Two factors comprised the latter. Factor 1 was labeled Negative Self-concept and Personal Maladjustment and accounted for 40% of the total variance, and Factor 2 was labeled Desire for Change and Negative Expectations and accounted for 6.3% of the total variance. The findings may be useful in identifying the specific dysfunctional beliefs and negative automatic thoughts exhibited by military recruits. Such information can also contribute to the development of more effective treatment interventions.     

The effect of time constraints and personality facets on general cognitive ability (GCA) assessment

General cognitive ability (GCA) is a recognized construct for predicting job performance and capacity to learn. However, it has recently been argued that the time constraints under which GCA is assessed might provoke test anxiety, which negatively biases GCA scores. This can then lead to erroneous rejection of qualified candidates in personnel hiring contexts. This paper aimed to investigate: (1) to what extent candidates’ GCA scores increase when tested without time constraints and the ability of this GCA score to predict job performance; and (2) the personality characteristics that hinder GCA test performance under time constraints. Results from two field studies conducted in an actual personnel selection context partially confirmed the hypotheses. They revealed that, aside from the improvement of all candidates’ GCA scores when time constraint was removed, only GCA assessed without time constraints predicts job performance. Furthermore, while all candidates’ scores were influenced by the time constraint condition, individuals who are anxious, low-impulse, low value-questioning and deliberating are more penalized by the time constraint condition of such testing and, thus, are more likely to be erroneously eliminated in a selection process.     

The location of sense of humor within comprehensive personality spaces: An exploratory study

The present paper tries to discover the position of sense of humor in personality space. Several definitions of humor are discussed and a review of studies relating personality and humor is given. The authors' conceptualization of humor is introduced and two studies are presented that tried to locate these humor dimensions within personality space. Our humor tests were given to two samples: these samples also had to answer several multidimensional personality inventories to cover the whole domain of temperament (e.g. EPQ, 16PF, FPI, STPI, SSS-IV and STAI). The Humor scores were correlated with each of the personality variables. The factor compositions of the best predictors for a humor category were used to arrive at a tentative hypothesis of the location of dimensions of humor in personality space. The results show that strong relationships between humor and temperament exist. Some of the hypotheses discussed in the literature were supported, but also some new hypotheses were derived from this study. All in all, the results show that the separation of appreciation of humor into the independent components of funniness and rejection is appropriate since they are located in different parts of the personality space.     

Scale 4 (Pd) of the MMPI and the diagnosis antisocial personality

The MMPI and a structured diagnostic interview were administered to 225 military offenders in an attempt to determine the relationship between Scale 4 (Pd) of the MMPI and a behavioral diagnosis of Antisocial Personality (AS). Individuals satisfying criteria for a diagnosis of AS were found to score significantly higher than inmates not satisfying these criteria on Scale 4, regardless of whether K- or non-K-corrected T scores were used. Several potential moderating variables were crossed with the AS measure but only confining offense (person crime vs nonperson crime) evidenced a statistically significant interaction with AS.     

Factor structure analysis of the Preschool and Kindergarten Behavior Scale scores in Spanish population

Social competence and antisocial behavior in children are interesting variables for researchers and educators. Nonetheless, there are few assessment instruments capable of measuring the two constructs in small children. The aim of this study is to verify the structural validity of the Preschool and Kindergarten Behavior Scale for Teachers and Caregivers (PKBS-2), in order to determine the theoretical model that best fits the data from a Spanish sample. 1509 children from preschool education (741 males and 768 females) from 3 to 6 years old (M= 3.78; SD= 0.815) participated in the study. Data was analyzed using the Statistical Package for the Social Sciences (SPSS-15.0) and the Structural Equations Program (EQS 6.1). The resulting models of social skills and behavioral problems show adequate fit indexes, statistically significant loadings, and a high internal consistency index (Cronbach's alpha). Lastly, the structural model confirms a two-factor structure: a first factor of Social Skills, comprising three variables (social cooperation, social interaction, and social independence), and a second factor of Behavior Problems, comprising two variables (externalization and internalization of problems).     

A comparative study of the dimensions and facets of the five-factor model in the diagnosis of cases of personality disorder

Two national samples of psychologists (n = 92, n = 89) rated personality disorder cases using either the five factors (domains) or the 30 facets of the five-factor model (FFM) to examine reliability and clinical utility of the model when used as a diagnostic tool. The cases were prototypic and nonprototypic cases representing the three clusters of personality disorders in the DSM-IV. Although confidence was higher using the factors rather than the facets to rate the cases, interrater reliability was similar and the facets were rated more useful for professional communication, case conceptualization, and treatment. Mean ratings for the prototypic cases supported the theorized relationships between those personality disorders and the FFM. Principal components factor analysis of the facet ratings largely replicated the structure of the FFM with only a few facets failing to load with their superordinate dimension in the model. Implications for use of the FFM with personality disorder are discussed.     

Pathological gambling and personality disorders: an exploratory study with the IPDE

This article describes the most frequent personality disorders related to pathological gambling. Participants included 50 pathological gamblers assessed with the IPDE, and 50 normative subjects from the general population with the same demographic features (age, sex, and socioeconomic level). Thirty-two percent of the clinical sample (vs. the 8% of the normative sample) showed at least one personality disorder. The most prevalent disorders were Borderline (16%), followed by Antisocial, Paranoid, Narcissistic, and Non-specified (8% each). Gamblers with personality disorders presented an average of 1.5 disorders and they reported higher gambling severity and more severe symptoms of anxiety, depression and alcohol abuse. The implications of this study for clinical practice and research are discussed.     

The Tennessee Self-Concept Scale and the normal personality sphere (16PF)

An examination of the internal structure of the Tennessee Self-Concept Scale (TSCS) and the interrelationship among the TSCS scales and the secondary dimensions of the Sixteen Personality Factor Questionnaire (16PF) supported three conclusions: (a) The primary dimension underlying the TSCS is positive self-evaluation, freedom from neurotic symptoms, or the absence of anxiety, (b) this central dimension of the TSCS aligns with the 16PF secondary Anxiety vs. Adjustment, and is virtually independent of the other dimensions of the normal personality sphere, and (c) the mutual orthogonality of extraversion, anxiety or neuroticism, and an empirically derived psychoticism scale provided some support for Eysenck's PEN theory of personality organization.     

Genetic associations with personality and mental toughness profiles of English academy football players: An exploratory study

Psychological characteristics influence the performance of youth football players and are significant predictors of development and success at adulthood. Although genetic factors may explain a considerable portion of inter-individual differences in psychological traits, psychogenetic research in football is scarce. As such, the purpose of this study was to examine the association of ten single nucleotide polymorphisms (SNPs) with personality and mental toughness profiles of academy football players. Seventy-three male under-12 to under-18 football players from a Category 3 English academy were genotyped for ten SNPs. Personality and mental toughness were assessed using a 50-item IPIP Big Five personality traits questionnaire and the Mental Toughness Index, respectively. Simple linear regression was used to analyse individual SNP associations with personality dimensions and mental toughness, whereas both unweighted and weighted total genotype scores (TGSs; TWGSs) were computed to measure the combined influence of all SNPs. There was a significant association between DRD3 (rs167771) and agreeableness (p = .043), where A/A homozygotes scored higher than G allele carriers. TGSs and/or TWGSs were significantly correlated with mental toughness and each personality dimension except openness, explaining between 3 and 17% of the variance. The results of this study suggest psychological characteristics of youth football players are partly determined by genetic factors.     

Perceptions of the utility of personality assessment for personnel selection in the South African context: An exploratory study

This study explored South African industrial psychologists’ perceptions of the utility of personality assessment for personnel selection. Eleven industrial psychologists (2 male, 9 female) from the Johannesburg area, South Africa were the participants. They participated in semi-structured interviews exploring their understanding of the place of personality assessment in personnel selection within organisational settings in South Africa and the common practices employed. Thematic analysis was used to analyse the data. Four dominant themes emerged from the data: person-environment fit; specific uses of personality tests; commonly used tests and validity and ethical concerns. Based on the findings, personality assessment use in South African industry settings appears multi-layered and consistently evolving.     

An exploratory investigation of the reliability and validity of the Independent-Interdependent Problem-Solving Style Scale

The Independent-Interdependent Problem-Solving Scale is based on Cross et al.'s conceptualisation of relational-interdependent self-construal. The IIPSS provides a relatively context-free measure of people's tendencies to solve problems independently or with the help of others. Because previous investigations have not provided extensive evidence for the reliability and validity of the IIPSS, the current research aimed to test the psychometric properties of this novel measure. Investigations of four student samples (combined N = 1157) and one sample comprised of academic researchers (N = 198) generally supported the reliability and validity of the IIPSS. Exploratory factor analysis of IIPSS items yielded a single factor structure. However, confirmatory factor analyses did not demonstrate good model fit for the one factor solution and instead yielded good model fit for two underlying factors. The IIPSS showed adequate test–retest reliability and predicted positive associations with social personality traits. It also showed no significant associations with measures of demand characteristics and social desirability. Future research needs to be undertaken to further assess the factor structure and address shortcomings of the present research such as utilising objective data in addition to self-reports to assess the scale's validity.     

An exploratory investigation of the personality correlates of aging using the Hand Test.

The Hand Test was administered to 27 older adults of both sexes (Mage = 66.56) to investigate possible changes in personality concomitant with normal aging. To control partially for such factors as cultural influences and intelligence differences a matched-pair design was used in which the test protocols of the older adults were matched with those of their children of the same sex (Mage = 36.44). Though the Hand Test has not been independently validated on older adults, results were consistent with past findings using projective techniques inasmuch as depletion and constriction of personality were noted. Criticisms of research on the clinical assessment of the elderly were discussed.     

An exploratory study of the relationship between diverse life events and specific personality disorders in a sample of suicide attempters

Personality disorder (PD) increases risk for suicidal behavior. Certain life events (LE) can precipitate suicidal behaviors in patients with PD. A fundamental question is whether specific combinations of LE and PD increase suicidal risk. Four hundred forty-six suicide attempters (SA) were recruited from emergency rooms. We used a healthy control group (n = 515) to identify the best cut-off point for the instrument used to diagnose PD. We used the DSM-IV version of the International Personality Disorder Questionnaire-Screening Questionnaire, the Mini International Neuropsychiatric Interview, and the Social Adjustment Scale to assess PD, Axis I disorders, and LE, respectively. After controlling for Axis I disorders, we found that "Death of spouse" preceded suicidal acts in those with antisocial PD (FET p = 0.024) and patients with narcissistic PD attempted suicide after being Fired at work (FET p = 0.002), among others. Our data suggest the presence of particular LE-PD associations in suicide attempters. Some LE-PD relationships appear independent of Axis I disorders in suicide attempters. This may offer a basis for specific targeted therapies or prevention programs aimed at decreasing suicidal risk.     

Exploring the validity of scores from the Rosenberg Self-Esteem Scale (RSES) in Burundi: A multi-strategy approach

The present study aimed to validate the Rosenberg Self-Esteem Scale (RSES) in Burundi, through a multi-strategy approach used in cross-cultural studies. Respondents were 906 health workers (men = 56%; caregivers 60%). They responded to a bilingual version of RSES. We utilised Confirmatory Factorial Analysis (CFA) with structural equation modelling and a back translation test to explore the structure of the RSES and the reliability of scores from the scale. Data from an independent sample were analysed for the reliability of scores assessment. CFA results suggested that the global RSES factor was likely contaminated by a method-effect; mainly associated with negatively worded items. Internal consistencies and a back-translation test demonstrated that the negatively worded items were unsuitable in this context. The independent sample study confirmed poor reliability and internal consistency of scores for both alternative language versions of the RSES. Our data suggested that an overall cultural effect, rather than a merely specific language effect, may undermine the cross-cultural transportability of the Western scale.
