Assertiveness,aggressiveness and Eysenck's personality variables

The relationship of scores on the Interpersonal Behavior Survey (IBS) and the Eysenck Personality Questionnaire (EPQ) were studied to investigate the relationship of assertiveness and aggressiveness to more basic dimensions of personality. This relationship was studied in two samples. Sample one consisted of 12 psychiatric inpatients, 67 college students and 69 state prison inmates. Sample two was made up of 50 psychiatric inpatients. The correlational results were highly similar in both samples. Significant negative correlations were found between the EPQ Neuroticism scale and IBS assertiveness scales; significant positive correlations were found between the EPQ Neuroticism and Psychoticism scales and the IBS aggressiveness scales, and significant positive correlations were obtained between the EPQ Extraversion scale and the IBS assertiveness scale. An ANOVA revealed a significant Neuroticism by Extraversion interaction on the IBS General Assertiveness, Rational scale. Neurotic introverts were found to have especially large deficits in assertive behavior. The results are generally consistent with Eysenck's theory of personality.     

Cross-cultural comparison of personality: Norway and England

Three hundred and seventy-seven male and 425 female Norwegian subjects completed the translated Eysenck Personality Questionnaire (EPQ). Factor comparisons all exceeded 0.97, so that the factors of Psychoticism (P), Extraversion (E), Neuroticism (N) and Social Desirability or Lie Scale (L) can be considered to be identical with those found in England. Sex differences were the usual, i.e. males scored higher that females on P and E but lower on N and L. Cross-cultural comparisons found no statistical differences between the personality scores of the two countries, except on Neuroticism, with both Norwegian sexes scoring significantly lower than their English counterparts. A slight tendency for Norwegian males to score lower on Social Desirability was detected.

Personality and female criminals in Bangladesh

A study is reported of female criminals at Dacca Jail, using the EPQ standardized in Bangladesh. The Ss of the present investigation were considered as a single group and also divided into groups according to the nature of the crime committed and their age. The major finding that clearly emerged from the study is that the female criminals returned very high P scores. They were also found to have elevated scores on N. It is suggested that the translated version of the EPQ be used with male criminal and psychiatrically-abnormal groups in future studies.     

Structural and functional equivalence of the Eysenck Personality Questionnaire within and between countries

The question was examined as to whether scores at the individual level and scores at the country level on the four scales of the Eysenck Personality Questionnaire (EPQ) have the same psychological meaning. Using data of 24 countries, it was found that the EPQ has different factorial structures at both levels. Both the Lie scale and the Psychoticism scale were shown to jeopardize cross-level equivalence. For further exploration of the meaning of the EPQ scales within countries and between countries country-level correlations were calculated with a variety of country characteristics such as Gross National Product, political indices, religiosity, Hofstede's measures, and subjective well-being. Significant findings for 38 countries included correlations of the EPQ scales with Hofstede's Masculinity, Diener's Subjective Well-Being, religiosity, the number of deaths in a country due to political violence, and bribery. The most striking finding was a substantial negative correlation of the Lie scale with Gross National Product and other wealth-related indices.     

Deliberate self-harm,clinical history and extreme scoring on the EPQ

Two hundred consecutive admissions to an inpatient psychiatric unit were assessed on the EPQ following recovery from the disturbance for which they were hospitalized. Case-history data was also checked for these patients and extended by using a clinical-history structured interview, also administered within 1 week of discharge. Results showed that for males, high P and high N was associated with a history of deliberate self-harm (DSH) by mutilation. High N was also associated with parental violence. In females, both low E and high N were associated with a history of self-mutilation. High N scores were also more likely to have appeared in court, and high P females were more likely to have a history of bedwetting and of parental violence.None of the associations between extreme scoring on the EPQ and self-mutilation were found for DSH by overdose.     

How the personality dimensions of neuroticism, extraversion and psychoticism relate to self-actualization

This study examines the relationship between the personality dimensions of ‘neuroticism’, ‘extraversion’, ‘psychoticism’, from the Eysenck Personality Questionnaire (EPQ) and ‘self-actualization’, measured by the Personal Orientation Inventory (POI) for 212 undergraduate students. The two major scales of the POI, (Time Competence and Inner Directed), both separately and as a combined measure of self-actualization were correlated with the scores obtained on the EPQ. The results showed the hypothesized significant negative relationship between neuroticism and self-actualization, and for females only, the hypothesized significant positive relationship between extraversion and self-actualization. Contrary to hypothesis, no relationship between psychoticism and self-actualization was found.     

Psychopathy and the personality dimensions of psychoticism,extraversion and neuroticism

The Eysenck Personality Questionnaire (EPQ) was administered to 173 male prison inmates for whom reliable assessments of psychopathy were available. Psychopathy was significantly correlated with the Psychoticism (P) scale (r = 0.16) and the Lie scale (r = 0.14), but not with the Extraversion (E) or Neuroticism (N) scales. Zone (octant) analysis indicated that psychopathy was not associated with any particular combination of P, E and N scores. Additional analyses, based on the discriminant function procedure described in the EPQ manual, indicated that inmates with high assessments of psychopathy were significantly less psychiatrically abnormal, in the EPQ sense, than were those with low assessments of psychopathy. A series of comparisons was also made between the P scale and a 22-item psychopathy checklist. The P scale was significantly correlated with six of the items, and with factors 1 (r = 0.30) and 4 (r = 0.19) that emerged from a principal components analysis of the checklist. Factor 1 is related to an impulsive, unstable lifestyle with no long-term commitments and factor 4 to the early appearance of antisocial behavior. It is argued that the P scale reflects the criminal, antisocial aspects of psychopathy and that the results probably have no direct implications for the suggestion that psychopathy and psychoticism are related in some fundamental way. A canonical analysis indicated that some interesting relations may exist between the EPQ variables and the psychopathy factors.

Lateral preference and students' worries: a correlation

A significant correlation was found between left-sided lateral preference as measured by the General Laterality subtest of the Lateral Preference Schedule and scores on the Student Worry Survey for 34 male college students but not for 44 female college students (M age = 19.9 yr.). This finding is consistent with other studies done with clinical populations showing correlations between left-handedness in males and various psychological disorders.     

The differential relationship between attribution and depression for male and female college students

This study tested for the presence of a differential relationship between attribution and depression for male and female college students. Results yielded no significant differences within male or female positive or negative internality, stability, globality, or composite attribution scores. However, a significant correlation was found between Attributional Style Questionnaire composite negative and Beck Depression Inventory scores for males, but not for females.     

Impulsivity in adults: motor inhibition and time-interval estimation

There is a need for the development of behavioral measures of impusivity in order to elucidate the specific qualities of impulsive persons. The relationships between two behavioral measures of impulsivity and several personality inventories frequently used to assess inpulsivity were examined using 40 male Ss. The behavioral measures involved a motor-inhibition (MI) task and time-interval (TI) estimation. The personality measures included the Extraversion (E), Psychoticism (P) and Neuroticism (N) scales of the Eysenck Personality Questionnaire (EPQ), Barrat's Impulsivity Scale (BIS) and Gough's Socialization Scale (So). Significant relationships between MI scores and E, BIS and a proposed dimension of impulsivity obtained by the formation of E-P quadrants were found. In addition, performance on this task was related to So, P and E-N quadrants in the predicted directions. The consistency of these results supports the use of this task as a behavioral measure of impusivity in adults. Although personality inventory scores were not related to estimations, significant (negative) correlations were obtained between TI estimations and MI scores. The results indicate that TI estimation by itself is not an adequate measure of impulsivity, but does have implications for understanding impulsive behavior.     

EPQ and the psychiatric patients of Bangladesh

The Eysenck Personality Questionnaire, standardized in Bangladesh, was administered to a group of 358 psychiatric patients—109 male and 108 female neurotics and 78 male and 63 female psychotics. The neurotic Ss were analysed separately according to sex, and were also divided into groups according to psychiatric nosology. The major findings that clearly emerged from the study of neurotic individuals were that they returned very elevated N scores and depressed E scores as against the norms, while the depressive patients of both sexes gave the lowest E scores. Most of the psychotic Ss of both sexes were diagnosed schizophrenic. The major finding of the investigation of psychotic individuals was that they returned much elevated scores on the psychoticism scale as compared with norms, and they also gave low E and high N scores. It is suggested that the EPQ be used to promote a better understanding and more efficacious therapeutic intervention of the psychiatrically ill person in this culture.     

Personality and the perception of TV violence

An experiment was carried out to investigate relationships between individuals' personality characteristics and their perceptions of violent TV portrayals. A panel of 40 viewers rated brief violent episodes from five categories of programming, contemporary British crime-detective series, American police series, westerns, science-fiction series and cartoons on eight scales. These responses were then related to viewers' scores on the N, E and P dimensions of the EPQ. Results showed that violent scores from contemporary settings were rated as more serious than scores from non-contemporary and fantastic settings. In addition, viewers exhibited individual differences in ratings of TV violence which were related to certain of their EPQ scores. In particular, high N scorers tended to perceive violence generally, but especially that from contemporary British drama, as more serious than did low N scorers. This study indicates the need to include personality measures in the analysis of audience reactions to TV violence.     

Further analysis of the social psychopathy scale

This paper presents a further examination of the Social Psychopathy Scale (SPS) which was designed to measure psychopathic-like characteristics in normal samples; until the present study, data was only available for U.S. subjects. The SPS, Socialization Scale (SO) and the EPQ were administered to 92 U.K. subjects. The mean scores and factor structure of the SPS obtained in the present study were compared with those obtained in a previous study with U.S. subjects and revealed only a limited degree of correspondence. There was a predicted negative correlation between the SPS and SO and predicted positive correlation between the SPS and the P-scale of the EPQ. There was some variability in the relationship between the SO and subscales of the EPQ with the factors of the SPS obtained in the present study. Two aspects of the results are discussed: the variability in the factor structure of the SPS, and the nature of the concept of social psychopathy.     

Premenstrual tension and personality

The premenstrual symptomalogy (PMT) of 165 students of nursing and midwifery was studied and their personality was assessed using the Eysenck Personality Questionnaire (EPQ). Thirty-four per cent of the Ss showed severe and 42% moderate PMT symptomatology. Ss with severe PMT symptomatology gave significantly higher scores in the neuroticism scale of the EPQ. Abdominal and pelvic pain as well as low back pain, i.e. symptoms of dysmenorrhoea, did not correlate with high neuroticism scores.

本文采用父母教养方式评价量表 (EMBU)和艾森克人格问卷 (EPQ)对 40名住院神经症患者进行了测查 ,结果发现艾森克人格问卷所测查的四种人格维度 E(内、外向 )、L (掩饰或社会性幼稚水平 )、N(神经质 )和 P(精神质或倔强、讲求实际 )得分分别与不良的父母教养方式如严厉惩罚、过度干涉和过分保护、拒绝与否认以及偏爱被试等因子分呈显著的相关关系。     

National differences in personality: India and England

This study reports comparisons between results on the Eysenck Personality Questionnaire (EPQ) obtained from 558 male and 636 female Indian Ss; the comparison group of the original standardized English Sample (Eysenck and Eysenck, 1975). Factor analysis of item correlations showed close correspondence between the factors extracted in the two samples, with indices of factor comparisons being well in excess of 0.97. The reliabilities in the Indian sample were only marginally lower than in the original English standardization group. Some items from the original EPQ did not load on the hypothesized factors; they were substituted by the extra items contained in the 101-item version of the EPQ used in India. The Indian data showed no sex differences with respect to extraversion; females were found to score higher on the Neuroticism and also slightly higher on the Lie scale than the males. The Lie scores for both males and females being quite high suggests a consistent trait of conformity in operation. It was concluded that the organization of personality in India is sufficiently similar to that in England to make national comparisons feasible since identical dimensions underlie the personalities of Indian and English Ss.     

Relationship between mental toughness and physical endurance

This study tested the criterion validity of the inventory, Mental Toughness 48, by assessing the correlation between mental toughness and physical endurance for 41 male undergraduate sports students. A significant correlation of .34 was found between scores for overall mental toughness and the time a relative weight could be held suspended. Results support the criterion-related validity of the Mental Toughness 48.     

The factorial structure of the 16PF and EPQ in Egyptian samples: A preliminary study

Three hundred and sixteen Egyptian undergraduates (164 males and 152 females) completed the 16PF questionnaire (Form A) and the EPQ. The Varimax orthogonal rotation procedure applied to the 16PF revealed two factors, neuroticism (N) and extraversion (E). The rotated Varimax factors of the combined 16PF and EPQ inventories showed three factors, i.e. N and E, in addition to psychoticism (P). Coefficients of factor similarity (CFS) are high between the corresponding extracted factors of N, E and P in the male and female groups. The present results therefore support the second-order, broader factors. They are highly replicable and invariant in the two Egyptian samples studied.
