Study of he personality profile of incarcerated female aggressors

This experimental study aims to determine the specifi c personality traits of female incarcerated aggressors in Romanian prisons, a category of inmates that has been insuffi ciently investigated regarding their personality profi le. The research sample consisted of 200 incarcerated women, defi nitively convicted for off enses including homicide, drug traffi cking and consumption, theft, and economic crimes. The investigation of the personality profi le of female aggressor inmates was conducted using the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ), the Nonverbal Personality Questionnaire in Five Factors (FFNPQ), and the Freiburg Personality Inventory (FPI). Analyzing and synthesizing the results of this research, we can conclude that female aggressor inmates exhibit a distinct personality profi le compared to female inmates who have committed non-violent off enses.

A questionnaire measure of adult attachment anxiety correlates with frontal hemispheric asymmetry in sleep spindle activity

Subjects with high levels of attachment anxiety and neuroticism were proposed to be characterized by higher relative right rather than left frontal activity. Since sleep spindles are argued to reflect enhanced offline neuroplasticity, higher spindle activity measured over the right frontal areas relative to the corresponding left frontal ones could index higher attachment anxiety and neuroticism. Our aim was to explore the relationship between the lateralization patterns of frontally dominant slow sleep spindles and questionnaire measures of adult attachment anxiety and neuroticism. Thirty-four healthy subjects (male = 19; Mage = 31.64; SDage = 9.5) were enrolled in our preliminary study. Second night EEG/polysomnography records and questionnaire measures of personality (Zuckerman–Kuhlman Personality Questionnaire) and adult attachment (Relationship Scales Questionnaire) were collected. Frontal slow sleep spindles were measured by the Individual Adjustment Method (IAM), whereas hemispheric asymmetry indexes of spindle occurrence rate, duration, and amplitude were derived as normalized left–right differences (electrode pairs: Fp1–Fp2, F3–F4, and F7–F8). Relative right lateralization of frontolateral and frontopolar slow sleep spindle density and mid-frontal slow spindle duration were associated with attachment anxiety, but spindle lateralization was less closely related to neuroticism. The relationships between frontal slow spindle laterality and attachment anxiety remained statistically significant even after controlling for the effect of neuroticism, whereas attachment avoidance–independence was not correlated with frontal slow spindle lateralization. Right frontal lateralization of slow sleep spindle activity might indicate attachment status in terms of the negative view of the self.

Exploratory examination of the effects of d-amphetamine on active-state functional connectivity: Influence of impulsivity and sensation-seeking status.

Recent advances in diagnostic research identified that individuals with higher impulsivity and sensation-seeking scores tend to report more positive subjective responses to stimulant drugs such as amphetamine. The current exploratory study hypothesized that differences in underlying mesocorticolimbic circuitry may mediate the relationship between personality and responses to stimulants due to its previously established implication in reward processes as well as the overlap between its dopaminergic projections and the pharmacodynamics of many stimulants. Forty participants (20 female) were recruited with relatively high- and low-impulsivity and sensation-seeking scores as defined by the Zuckerman-Kuhlman Personality Questionnaire (Form IIIR; Zuckerman, Kuhlman, Joireman, Teta, & Kraft, 1993) for a double-blind, placebo-controlled, intranasal amphetamine administration study conducted within an MRI scanner. Active state seed-to-voxel connectivity analyses assessed the effects of amphetamine, personality, subjective responses to amphetamine, and their interactions with mesocorticolimbic seeds on data collected during monetary incentive delay and go/no-go task performance. Results indicated that amphetamine administration largely disrupted brain activity as evidenced by connectivity values shifting toward no correlation among brain stem, striatal, and frontal cortex regions. Additionally, associations of impulsivity and connectivity between ventral tegmental and medial orbitofrontal as well as lateral orbitofrontal and putamen regions were inverted from negative to positive during the placebo and amphetamine conditions, respectively. Personality was unrelated to subjective responses to amphetamine. Results are interpreted as providing evidence of underlying differences in mesocorticolimbic circuitry being a potential target for requisite diagnostic and treatment strategies implicated with stimulant use disorders, but further research is needed.

Persistent Impostor Phenomenon Is Associated With Distress in Medical Students.

Medical student distress and mental health needs are critical issues in undergraduate medical education. The imposter phenomenon (IP), defined as inappropriate feelings of inadequacy among high achievers is linked to psychological distress. We investigated the prevalence of IP among first-year medical school students and its association with personality measures that affect interpersonal relationships and well-being. Two hundred fifty-seven students at a large, urban, northeastern medical school completed the Clance Impostor Phenomenon Scale (CIPS), Jefferson Scale of Empathy, Self-Compassion Scale, and Zuckerman-Kuhlman Personality Questionnaire immediately before beginning their first year of medical school. At the end of their first year, 182 of these students again completed the CIPS. Eighty-seven percent of the entering students reported high or very high degrees of IP. Students with higher IP scores had significantly lower mean scores on self-compassion, sociability self-esteem (P<.0001 for all), and getting along with peers (P=.03). Lower IP scores were related to lower mean scores on neuroticism/anxiety and loneliness (P<.001 for both). Women obtained a higher mean IP score than men. IP scores at the end of the school year increased significantly compared with the beginning of the year (P<.001), both in frequency and intensity of IP. IP was common in matriculating first-year medical students and significantly increased at year's end. Higher IP scores were significantly associated with lower scores for self-compassion, sociability, self-esteem, and higher scores on neuroticism/anxiety.

Recreational Activities and d-Amphetamine Effects in High and Low Sensation Seekers

This study examined the behavioral effects of d-amphetamine and recreational activities, alone and in combination, in high and low impulsive sensation seekers. Healthy 18-27 year-old participants, scoring in the upper (N=8) or lower (N=8) third of college students on the impulsive sensation-seeking scale of the Zuckerman-Kuhlman Personality Questionnaire, completed eight test days in which sessions were completed before (i.e., baseline) and 60, 120 and 180 minutes after d-amphetamine (0, 10 mg/70 kg) administration. Between sessions, subjects completed recreational activities (movies, music, reading, videogames) identified as high or low in sensation value. Each of four conditions (low and high sensation value activities combined with placebo and active drug) was administered under double-blind conditions on 2 days according to a randomized-block design. Typical stimulant-like cardiovascular and task performance effects were engendered by d-amphetamine; consistent with previous research, the magnitude of drug effects were greater among high sensation seekers. High sensation value activities engendered independent stimulant-like effects on subject ratings. These results suggest that d-amphetamine and high sensation stimulus materials may activate a common neurobiological substrate, likely the mesolimbic dopamine system, and that individual differences in sensation seeking status play a role in vulnerability to stimulant drug abuse.

Psychological Characteristics of Patients with Diabetes

Abstract The aim of this study is to establish the psychological characteristics of patients with diabetes. In the present study we included subjects with diabetes (n=60), and control group (n=62). In order to study the psychological characteristics of patients with diabetes, we have applied the following tests: Zuckerman-Kuhlman Personality Questionnaire (ZKPQ), Strategic Approach to Coping Scale (SACS), Cognitive Emotion Regulation Questionnaire (CERQ), Young Schema Questionnaire (YSQ-S3), Attitudes and Beliefs Scale (ABS II). The results of this study outlined psychological characteristics of patients with diabetes which consists of neurotic, anxious personality with a high level of activity, dysfunctional coping strategies like: indirect action, antisocial action, aggressive action and catastrophizing, irrational thinking and few maladaptive cognitive patterns. The study highlighted the need to restructure the maladaptive cognitive schemes, irrational beliefs, dysfunctional coping strategies for people with diabetes with a psychological program in order to improve endocrine symptoms and increase quality of life.

Familial aggregation of anxiety disorder subtypes and anxious temperament in the NIMH Family Study of Affective Spectrum Disorders

BackgroundEvidence from family and twin studies suggests that mood and anxiety disorders, and related temperamental factors may share common etiologic factors. We examine the familial aggregation and coaggregation of anxiety disorder subtypes and anxiety-related temperamental traits, and their association with mood disorders. MethodsA total of 477 probands and 549 first-degree adult relatives from a large community based family study of affective spectrum disorders completed semi-structured diagnostic interviews and self-reported assessments of temperamental traits including: negative affectivity on the ‘Positive and Negative Affect Schedule’ (PANAS), neuroticism anxiety on the ‘Zuckerman-Kuhlman Personality Questionnaire’ (ZKPQ), and anxiety sensitivity on the ‘Anxiety Sensitivity Index’ (ASI). ResultsThe anxiety-related temperamental traits of negative affectivity, neuroticism anxiety and anxiety sensitivity had significant familial specificity, even after controlling for comorbid mood and anxiety disorders in probands and relatives. Yet, these traits in probands did not predict anxiety disorders in relatives. Although some anxiety subtypes were familial, there were no longer familial links between anxiety disorder subtypes (generalized anxiety disorder, social anxiety or panic disorder) after controlling for mood disorder subtypes in probands and relatives. LimitationsCross-sectional interviews were used to estimate disorders, and self-report measures were used for temperamental traits. ConclusionsThese results confirm previous research regarding familial overlap between anxiety subtypes and mood disorders, however their shared liability cannot be fully explained by anxiety-related temperamental traits. These findings suggest that anxiety-related temperamental traits may indicate a vulnerability for mood and anxiety disorders or a potential consequence of these conditions.

Personality of patients with central serous chorioretinopathy.

Central serous chorioretinopathy (CSC) is a disease of the retina that is a frequent cause of mild to moderate visual impairment. The disease can be precipitated by psychosocial stress and hypercortisolism while full remission will often be spontaneous within a few months. Risk factors have included male gender, increased plasma cortisol due to other conditions or steroid use and Type A behavior. This is a cross-sectional study comparing three research groups that included 100 CSC patients, 200 healthy volunteers, and 200 patients with other ophthalmic disease on their results in the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ). CSC patients differed from the other subjects on increased high Neuroticism-Anxiety, low Sociability, and high Aggression-Hostility. Since high Neuroticism is related to increased cortisol levels only in males, and high Aggression-Hostility is related to increased cortisol response, these findings point to the possibility of a robust neurobiological background to the etiopathogenesis of CSC that merits further research. The association of Type A behavior with CSC may be a spurious one and its widespread reference in ophthalmology texts should be re-examined.

The location of coping strategies within the Alternative Five Factor Model of personality

This study aimed to determine which personality dimension(s) as measured by the Zuckerman-Kuhlman Personality Questionnaire best explain a given coping strategy as measured by the COPE-48. Additionally, to clarify the location of these strategies in the broader framework of personality structure. Neuroticism-Anxiety contributed mostly to strategies focused on emotions, acceptance and denial, Activity to proactive and resolute strategies, and Sociability to obtaining emotional support and advice. Moreover, Impulsive Sensation-Seeking contributed to denial and substance use while Aggression-Hostility to focus on and venting of emotions, and inversely to restrain coping. Besides, we replicated the approach-avoidance axis and obtained an independent component grouping Religion and the inverse of Drugs, Humor and Impulsive Sensation-Seeking. Positioning coping strategies within the well-known, broader and multidimensional space of personality structure may help in a better understanding of its organization and a rethinking of its conceptualization including their underlying neurobiological basis, ultimate evolutionary nature and survival functions.

Decreased oxytocin plasma levels and oxytocin receptor expression in borderline personality disorder.

Borderline personality disorder (BPD) is characterized by intense affective reactions with underlying social and interpersonal cognitive deficits. Oxytocin has largely been associated with both stress regulation and social cognition in psychiatric patients and in non-clinical populations in previous studies. Finally, abnormal oxytocin levels have been preliminary reported in BPD patients. 53 patients with moderate-severe BPD and 31 healthy control subjects were investigated for plasma levels of oxytocin and protein expression of oxytocin receptor in blood mononuclear cells. Clinical assessments were made for severity, functionality, and comorbidity with axis I and II conditions. Oxytocin plasma levels were significantly lower in BPD patients compared with controls. In addition, protein expression of oxytocin receptor was significantly reduced in the BPD group. A positive correlation was found between plasma oxytocin levels and the activity index score of the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ). Oxytocin receptor protein expression, on the contrary, had a negative correlation with the ZKPQ sociability index score. Results support the evidence of a dysfunction of the oxytocin system in borderline personality disorder, which could be involved in emotional dysregulation and interpersonal disturbances in these patients.

Eating Disorder Risk and Personality Factors in Adolescent Girls

There is a consistent research that shows that adolescents have frequent concerns and worries about their body and self-image. One important factor is the biological and physiological context of development in adolescence, a stage of significant transformation in overall human development. A sample of 185 adolescent girls, aged between 18 and 21 years old, all residing in Constanta County, has been assessed with 4 questionnaires: Garner’s Eating Disorder Inventory (2004), Zuckerman-Kuhlman Personality Questionnaire (2002), The Body Esteem Scale for Adolescents and Adults (Mendelson, Mendelson, & White, 2001), and the Sociocultural Attitudes toward Appearance Scale (Thompson, van den Berg, Roehring, Guarda, & Heinberg, 2004). The purpose of the study was to explore the relationship between the risk of eating disorders and various psychological traits and variables. We examined all variables the questionnaires measured and selected only the statistically confirmed hypotheses (for p<.05). We obtained significant correlations between the risk of eating disorders and ineffectiveness, interpersonal problems, affective problems, excessive control, neuroticism-anxiety, body esteem, the internalization of the perfect athletic body, the internalization of the perfect ideal body and the pressure of having a perfect appearance. Results are discussed with regard to the psychological implications of this study and the need for additional research.

Empathy as related to gender, age, race and ethnicity, academic background and career interest: A nationwide study of osteopathic medical students in the United States.

ContextResearch on associations between medical student empathy and demographics, academic background and career interest is limited, lacks representative samples and suffers from single institutional features. This study was designed to fill the gap by examining associations between empathy in patient care, and gender, age, race and ethnicity, academic background and career interest in nationwide, multi‐institutional samples of medical students in the United States and to provide more definitive answers regarding the aforementioned associations, with more confidence in the internal and external validity of the findings.MethodsFour nationwide samples participated in this study (n = 10 751). Samples 1, 2, 3 and 4 included 3616 first‐year, 2764 second‐year, 2413 third‐year and 1958 fourth‐year students who completed a web‐based survey at the end of the 2017‐2018 academic year. The survey included questions on demographics, academic background and career interest, the Jefferson Scale of Empathy, and the Infrequency Scale of the Zuckerman‐Kuhlman Personality Questionnaire to control for the effect of ‘good impression’ response bias.ResultsStatistically significant and practically important associations were found between empathy scores and gender (in favour of women), race and ethnicity (in favour of African‐American and Hispanic/Latino/Spanish), academic background (in favour of ‘Social and Behavioural Sciences’ and ‘Arts and Humanities’ in Samples 1 and 2) and career interest (in favour of ‘People‐Oriented’ and ‘Psychiatry’ specialties).ConclusionsSpecial features of this study (eg, nationwide representative samples, use of a validated instrument for measuring empathy in patient care, statistical control for the effect of ‘good impression’ response bias, and consistency of findings in different samples from multiple institutions) provide more definitive answers to the issue of correlates of empathy in medical students and increase our confidence in the validity, reliability and generalisability of the results. Findings have implications for career counselling and targeting students who need more guidance to enhance their empathic orientation.

Predicating Attitude Toward Learning Communication Skills in Medical Students of Shahid Beheshti University

Background: The ability of communicating with people is of great importance for physicians. Predicting unknown variables like personality traits is one of the important impressive issues in choosing future medical experts in medical training. Regarding this, medical colleges have training programs all around the world. The present study aimed to investigate the attitude toward learning communication skills based on the personality traits of medical students. Materials and Methods: This correlational study was done in 2019 and the participants were medical students who were selected using a convenience sampling method. Zuckerman-Kuhlman personality questionnaire and communication skills attitude scale (CSAS) were used for data collection. CSAS was used to assess positive and negative attitudes. Results: The results showed that only the sociability dimension among the five dimensions of personality had a significant relationship with attitude toward learning communication skills (P=0.018). Moreover, significant relationships of gender (P=0.022), mother’s education level (P=0.049), and residence (P=0.036) with attitude to learning communication skills were found. Conclusion: According to the results, the dimension of demographic characteristics is effective in improving communication skills of medical students. Therefore, it is recommended that it should be considered in medical curriculum development and revision and modifications.

Personality Factors and Subjective Cognitive Decline: The FACEHBI Cohort.

Individuals with subjective cognitive decline (SCD) have the perception of memory problems without showing impairment on standardized cognitive tests. SCD has been associated with an increased risk of developing Alzheimer's disease (AD). Neuroticism and openness personality dimensions have also been associated with SCD and AD. From the aforementioned, we aimed to ascertain whether the dimensions and traits defined by the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ) differentiate between individuals with SCD and the general population (GP). A total of 187 participants with SCD and mild affective symptomatology recruited from the Fundació ACE Health Brain Initiative (FACEHBI) project completed the ZKPQ. Each SCD participant was matched by sex and age to an individual from the GP. Both samples included 71 men and 116 women with a mean age of 65.9 years. Results indicated that the SCD group scored significantly lower in Neuroticism-Anxiety and Activity than the GP group. Only Activity remained statistically significant in a multivariate analysis. These findings suggest that individuals with SCD have a low energy level and a dislike for an active and busy life. From the obtained results and knowing additional physical activities may delay the conversion from normal aging to cognitive impairment, we encourage promoting this lifestyle in daily routine. The assessment of personality may result in an SCD plus feature, which may serve as an upgrading strategy for future research.

Does Empathy Decline in the Clinical Phase of Medical Education? A Nationwide, Multi-Institutional, Cross-Sectional Study of Students at DO-Granting Medical Schools.

PurposeTo examine differences in students’ empathy in different years of medical school in a nationwide study of students of U.S. DO-granting medical schools.MethodParticipants in this cross-sectional study included 10,751 students enrolled in 41 of 48 campuses of DO-granting medical schools in the United States (3,616 first-year, 2,764 second-year, 2,413 third-year, and 1,958 fourth-year students). They completed a web-based survey at the end of the 2017–2018 academic year that included the Jefferson Scale of Empathy and the Infrequency Scale of the Zuckerman-Kuhlman Personality Questionnaire for measuring “good impression” response bias. Comparisons were made on empathy scores among students in different years of medical school using analysis of covariance, controlling for the effect of “good impression” response bias. Also, comparisons were made with preexisting data from students of U.S. MD-granting medical schools.ResultsA statistically significant decline in empathy scores was observed when comparing students in the preclinical (years 1 and 2) and the clinical (years 3 and 4) phases of medical school (P < .001); however, the magnitude of the decline was negligible (effect size =0.13). Comparison of findings with MD students showed that while the pattern of empathy decline was similar, the magnitude of the decline was less pronounced in DO students.ConclusionsDifferences in DO-granting and MD-granting medical education systems, such as emphasis on provision of holistic care, hands-on approaches to diagnosis and treatment, and patient-centered care, provide plausible explanations for disparity in the magnitude of empathy decline in DO compared with MD students. More research is needed to examine changes in empathy in longitudinal study and explore reasons for changes to avert erosion of empathy in medical school.

Cross-Border Reproductive Care: Psychological Distress in A Sample of Women Undergoing In Vitro Fertilization Treatment with and without Oocyte Donation.

BackgroundCross-border reproductive care (CBRC) refers to the movement of patients to foreign countries for fertility treatment. Limited evidence indicates that this phenomenon is associated with a risk of psychologi- cal distress, but few studies on the psychological impact of CBRC are currently available. The aim of this study was to compare the anxiety and depression levels of a group of cross-border patients with a local Spanish patient group, both of which underwent in vitro fertilization (IVF) treatment. We also sought to explore the clinical, sociodemographic and personality profiles of the CBRC group and local women.Materials and MethodsThis present cross-sectional study was conducted on 161 infertile females (71 CBRC patients and 90 local women) who were undergoing IVF treatment. The following questionnaires were used to collect data: Spielberger State Anxiety Inventory (STAI-S), the Beck Depression Inventory-II (BDI-II) and the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ). Sociodemographic, clinical, reproductive and CBRC variables were also recorded.ResultsCBRC patients, specifically CBRC oocyte recipients, showed higher levels of anxiety compared to lo- cal women. However, no significant differences in depression scores were found between both groups. Finally, when analysing personality, the Activity scale scores of the ZKPQ were found to be higher in CBRC oocyte recipients, which indicated a greater tendency for general activity and higher energy levels.ConclusionCBRC oocyte recipient women may have greater vulnerability to anxiety than local women prior to infertility treatment. Screening and psychological support protocols for anxiety in this population should be considered.

Psychological factors and risk of mortality after spinal cord injury

Objective: Identify the association of personality and purpose in life with competing risks of multiple causes of death after spinal cord injury (SCI), using data from the SCI Longitudinal Health Study. Design: Prospective cohort study with data collected in 1997–1998 and 2007–2009. Mortality status determined as of December 31, 2016. Setting: Specialty hospital in the Southeastern United States. Participants: 3070 adults with chronic (>1-year), traumatic SCI. Interventions: N/A. Outcome Measures: We examined 6 psychological factors (Purpose in Life and 5 scales of the Zuckerman-Kuhlman Personality Questionnaire) and risk of mortality due to 6 specific causes of death, building on published analyses of behavioral and health/clinical risk and protective factors. Results: There were 803 deaths. Four of the 6 psychological factors were predictive of all-cause mortality. All except 1 personality scale were related to cause-specific mortality. Psychological factors were most predictive of unintentional injury deaths. Purpose in life was protective of death due to pneumonia; whereas, Activity was protective of death due to diseases of heart and blood vessels and to unintentional injury. Sociability, Impulsive-Sensation Seeking, and Neuroticism-Anxiety were risk factors for death due to unintentional injury. Neuroticism-Anxiety was related to death due to septicemia. There were no significant psychological predictors of cancer. Conclusions: Rehabilitation professionals have a central role in promoting purpose in life as a means of increasing longevity. By assessing personality factors predictive of specific causes of mortality, those at risk may be targeted for cause-specific prevention strategies.

Validity and reliability of Chinese version of 28-item Substance Use Risk Profile Scale in Chinese adolescents and young adults

The present study aimed to explore the validity and reliability of the Chinese version of the 28-item Substance Use Risk Profile Scale (SURPS) and provide an effective assessment tool for personalities related to substance use by which to predict and intervene in substance use cases. A total of 2114 Chinese adolescents and young adults (age 19.44 ± 1.63 years old) were enrolled. The results showed that the modified SURPS-SL_r model fit well (χ2/df = 5.15, p < 0.01, CFI = 0.851, TLI = 0.835, RMSEA = 0.037, SRMR = 0.063), indicating that the structure of the SURPS was suitable for Chinese adolescents and young adults. The SURPS significantly correlated with the Satisfaction with Life Scale, Subjective Health Complaints Index, Beck Depression Inventory, Zuckerman-Kuhlman Personality Questionnaire, and Neuroticism Extraversion Openness Five-Factor Inventory (r = 0.22 ~ 0.60, all ps < 0.01), indicating that the criterion validity of the SURPS was good. The Cronbach’s α of SURPS and its dimensions were 0.74~0.83, which suggested the SURPS has good reliability. Therefore, the Chinese version of the 28-item SURPS is an effective and reliable measure of personalities linked to substance use in Chinese adolescents and young adults.

In memoriam of Marvin Zuckerman: His impact on Spanish Psychology.

The work of recently deceased Marvin Zuckerman is well-known in Psychology. Zuckerman is mainly known around the world for describing the nature of the Sensation Seeking personality trait (with a strong biological basis related to physiology, endocrinology, brain biochemistry and genetics), and its practical usefulness in explaining many human behaviors, especially high-risk behaviors. The article refers to biographical aspects of Zuckerman's career, and presents and presents an outline of results produced in Spain within the Zuckerman framework. We summarize studies conducted in our context with the Sensation Seeking Scale, form V (SSS-V), the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ), the new Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) and its short form (ZKA-PQ/SF) about psychometric and biological aspects of Zuckerman's theory. Results support the good psychometric properties of the Zuckerman instruments, the transcultural viability of his personality model, and their multiple biological correlates (gonadal hormones, genetic polymorphisms, and electrophysiological variables such as the startle reflex and frontal spectroscopy [fNIR]). The whole picture demonstrates the great usefulness of Zuckerman's theoretical framework in personality psychology research.
