A psychometric investigation of the eysenck personality questionnaire (revised) and its relationship to the I.7 impulsiveness questionnaire

The present study investigated the psychometric properties of the Eysenck Personality Questionnaire-Revised (EPQ-R) and the I.7 Impulsiveness Questionnaire. 307 Ss (215 female, 92 male) completed the EPQ-R and the I.7. Scale means and the standard deviations were calculated, scale reliability tested, scale scores intercorrelated and the resulting matrices were factor-analysed. The items from the EPQ-R and the I.7 were submitted to an item factor analysis. The results of the present study were quite similar to those reported by Eysenck, Eysenck and Barrett (1985) for the EPO-R and those reported by Eysenck, Pearson, Easting and Allsopp (1985) for the I.7. It was concluded that the EPQ-R represents an improvement on the 90-item EPQ and that the I.7 represents an adequate and reliable measure of Impulsiveness, Venturesomeness and Empathy. The relationships between the EPQ-R factors and the I.7 factors are also discussed.     

A sensation seeking scale for children: Further refinement and psychometric development

A revision of the Sensation Seeking Scale for Children (SSSC) was standardized and validated on a community sample of 660 elementary- and middle-school children and 168 clinic-referred male children. Factor analysis of the combined samples yielded three unique factors, entitled Thrill and Adventure Seeking, Drug and Alcohol Attitudes, and Social Disinhibition. Psychometric indices of reliability and validity were acceptable, but test-retest reliability was only moderate. Differences in SSSC scores according to sex, ethnic group, age, and intellectual status were similar to those found previously with the adult Sensation Seeking Scales. Consistent with documented relations between adult antisocial personality and sensation seeking, the SSSC distinguished boys with conduct disorder (CD) from clinic controls, but the SSSC scores of boys with CD did not differ from those of the community sample boys. Discussion includes suggestions as to the continued study of the assessment of sensation seeking in children.This research was supported by National Institutes of Health Grant 1-R01-MH42529-04 and is based on the doctoral research of the first author.     

Boredom proneness in anger and aggression: effects of impulsiveness and sensation seeking

The present study was a replication and extension of Rupp and Vodanovich’s (1997) work on the role of boredom proneness in anger expression and aggression. In addition to replicating their primary analyses, impulsiveness and sensation seeking were included to determine the potential impact of these variables on the relationships between boredom proneness and anger and aggression. Two hundred and twenty-four college student volunteers completed measures of boredom proneness, impulsiveness, sensation seeking, anger expression, and aggression. Findings were consistent with Rupp and Vodanovich (1997) but demonstrated more pervasive effects of external boredom proneness on aggression. Hierarchical multiple regression analyses demonstrated that the relationships between external boredom proneness and trait anger, anger expression/control, and aggression persisted even after accounting for impulsiveness and sensation seeking. Boredom due to a lack of external stimulation predicted one’s propensity to experience anger, maladaptive anger expression, aggression, and deficits in anger control.     

A psychometric investigation into the body-cathexis scale

The Body-cathexis Scale is examined to assess its psychometric properties. Results indicate a strong unidimensional measure with high internal consistency. It is recommended as a scale for research into the role of body feelings in self-concept and personality.     

Factor structure and psychometric features of the Italian version for the EPQ-R

Factor structure and psychometric properties of the Eysenck Personality Questionnaire—Revised were investigated in an Italian sample of 553 subjects (328 females and 225 males). The main psychometric features of the questionnaire are similar to those reported for the original English form. Factor analysis, however, showed six (out of 32) items of the P scale, referring chiefly to compliance to formal rules of conduct, to have their highest loadings on the Lie factor. The consistency of this finding with previous results suggests that, in the Italian context, these items tend to be more closely connected with the social conformity aspect of the Lie scale than with the psychopathy facet of Psychoticism and should be excluded from the scoring of the P dimension.     

On the replicability of the factorial structure of the sensation seeking scale

The present investigation sought to further examine the underlying factorial structure of the Sensation Seeking Scale (SSS). Since the cross-national replicability of the structure postulated by Zuckerman was studied recently by researchers from Australia and Canada using the SSS form V (Ball, Farnill and Wangeman, 1983; Rowland and Franken, 1986), it seemed worthwhile to compare their results with the results obtained in a non-English speaking culture.One-hundred-and-sixty-nine Israeli female students completed the Hebrew version of the SSS within a selection type setting. The factor analytic results by-and-large replicated three out of the four Sensation Seeking subfactors identified by Zuckerman. A comparison of the factor analytic results with those obtained in the Australian and Canadian studies yielded a considerably high congruence between the Israeli and the Canadian samples. However, a lower congruence was achieved when each of these samples was compared with the Australian sample. As a result of the cross-national comparison, 16 items were identified as inadequate. In spite of the general replicability of the factor structure of the SSS in several cultures, the findings of this study support the conclusion reached by Ball et al. (1983) and by Roland and Franken (1986) that a refinement of the scale is desirable.     

Relationship between the sensation seeking scale and a biographical inventory designed to predict risk-taking behavior

One hundred and five students were administered both Zuckerman's Sensation Seeking Scale (SSS) and the Torrance-Ziller biographical inventory (BI) for measuring risk-taking tendencies. Correlations between the BI and selected subscales on the SSS were positive and significant. However, the proportion of explained variance does not suggest that the SSS and the BI are tapping the same dimension.     

Mediational effects of sensation seeking on the age and financial risk-taking relationship

The current study examined the potential mediating role of sensation seeking in the well-established negative relationship between age and financial risk-taking. A total of 299 participants, aged 17–90 years, allocated hypothetical money into mutual funds that varied in risk and completed a sensation seeking measure. Hierarchical multiple regressions revealed that the amount of variability age accounted for in risk-taking (4.1%; β = −.22) was significantly reduced when sensation seeking was controlled for (0.8%; β = −.12). A Sobel test revealed that sensation seeking fully mediated the aforementioned relationship. Results suggest sensation seeking’s role as a mediator in more physiologically arousing risk-taking contexts (e.g., surfing). Discussion recommends investigating potential biologically and cognitively-rooted mediators and moderators of the age and risk-taking relationship.     

On the construct validity of the sensation seeking scale in a non-english-speaking culture

The purpose of the present study was to examine the structure validity of Zuckerman's Sensation Seeking Scale in a non-English-speaking culture. A nonmetric multidimensional scaling technique (SSA) was employed for analyzing the responses of 272 Israeli male applicants for a job for which sensation seeking was of special relevance. The general findings replicated the structure postulated by Zuckerman. Only 1 in 8 of the items were mislocated, all of which were indicated as inappropriate in previous factor-analytic studies conducted in other nations.     

Love styles,relationship experience,and sensation seeking: A test of validity

The present study was designed to test the validity of a typology and measure of styles of loving by examining the relationships among love styles, romantic experience and sensation seeking. Male and female research participants completed the Hendrick's (1986) Attitudes toward Love Scale and a measure of sensation seeking and answered a variety of questions about their experiences with romantic relationships. Results provided some evidence of the validity of the measure and conceptualization of love styles. However, questions were also raised about the validity of some of the scales.     

A genetic and environmental analysis of sensation seeking

The genetic and environmental contributions to the trait of sensation seeking were analyzed using the responses of 422 pairs of twins to the Sensation Seeking Scale (Form IV). The biometrical method of Jinks and Fulker was applied to the data. The data fit the model indicating the likelihood of a predominantly additive gene action controlling the general trait. The heritability figure of 58% (69% of the reliable variance) was quite high for a personality trait. Data from other studies suggest that the heritability of the personality trait rests upon specific inherited biological traits, such as the biochemicals of the brain and gonadal hormones which affect arousability of the central nervous system and relevant traits, such as mood, impulsivity, risk taking, and sociability.     

A psychometric investigation of the Eysenck Personality Questionnaire.

The Eysenck Personality Questionnaire was administered to 139 females and 123 males. Scale statistics were obtained and hierachial factor analyses were performed. The P scale was found to have low internal consistency reliabilities and to covary with the L scale in the female subsample. Factor analyses showed recovery of E scale items in a secondary factor, Social Extraversion, without an impulsivity primary factor. No P and N dimensions recovered; rather components of each scale interrelated in two meaningful dimensions at the tertiary level.     

A psychometric examination of the multidimensional perfectionism scale

The Multidimensional Perfectionism Scale (MPS), developed by Frost, Marten, Lahart, and Rosenblate (1990), was constructed using an all female sample at an elite university. This study examined the psychometric properties of the instrument using a more typical sample (n=278) of college students from a large state university and a small liberal arts college, both located in the South. Significant differences were found on the overall MPS score as well as six of the seven subscales between this sample and that of Frostet al. No gender differences were found for any of the MPS scores. Internal reliability was found to be .88 for the total score, with subtests ranging from .57 to .95. Interscore correlations were relatively consistent with the Frostet al. sample except for a negative correlation between the PS subscale and the total score. There was a strong confirmation of the underlying factor structure reported by Frostet al. The overall impression was that the MPS is a psychometrically sound instrument of potential value in studying the construct of perfectionism.     

Individual differences in the development of sensation seeking and impulsivity during adolescence: further evidence for a dual systems model

Consistent with social neuroscience perspectives on adolescent development, previous cross-sectional research has found diverging mean age-related trends for sensation seeking and impulsivity during adolescence. The present study uses longitudinal data on 7,640 youth from the National Longitudinal Study of Youth Children and Young Adults, a nationally representative sample assessed biennially from 1994 to 2006. Latent growth curve models were used to investigate mean age-related changes in self-reports of impulsivity and sensation seeking from ages 12 to 24 years, as well individual differences in these changes. Three novel findings are reported. First, impulsivity and sensation seeking showed diverging patterns of longitudinal change at the population level. Second, there was substantial person-to-person variation in the magnitudes of developmental change in both impulsivity and sensation seeking, with some teenagers showing rapid changes as they matured and others maintaining relatively constant levels with age. Finally, the correlation between age-related changes in impulsivity and sensation seeking was modest and not significant. Together, these results constitute the first support for the dual systems model of adolescent development to derive from longitudinal behavioral data.     

A further investigation of the life-world

Conclusions My personal way to phenomenology revealed to me qualities that seem to be essential to one's sense of everyday social reality. Having been victimized I became aware of some of the basic elements that lie beneath the intersubjectivity of the taken-for granted life-world.Death is the ultimate problematic event and the individual is shielded from it by his or her life-world. We hope that actions are repeatable and that others are trustworthy so that we will not confront our own isolation and our own mortality. Although one is alone in death, we act as if we are, and always will be, fundamentally with others within a shared and orderly social world. In short, we avoid our finite individuality through the hopeful construction of a sense of permanent and fundamental sociability. By sheltering ourselves within the life-world, we are, in essence, hoping that we will not die. In this sense, the life-world is a fundamentally deceptive construction. Yet, in this same sense, the life-world is also the source of social and cultural progress. Paradoxically, our sense of everyday reality is both deceptive and productive.The author wishes to express his gratitude to Susan Meisenhelder, George Psathas, and Richard Zaner for their comments on earlier drafts of this paper.     

A comparison of impulsivity and sensation seeking in pathological gamblers and skydivers

The aim of this study was to compare pathological gamblers and skydivers in relation to measures of impulsivity and sensation seeking. The Eysenck Impulsivity Scale - Narrow Impulsiveness Subscale and the Arnett Inventory of Sensation Seeking were administered to pathological gamblers (n = 29), skydivers (n = 93), and a control group (n = 43). A two-way multivariate analysis of variance was conducted to explore differences in impulsivity and sensation seeking between the groups and possible group by gender and group by age interaction effects. The significant effects were further investigated using follow-up univariate analysis of variance. The results showed significant main effects of Group, Gender and Age, and a significant Group by Gender interaction effect. The results showed no statistically significant differences in impulsivity between pathological gamblers and skydivers; however, both groups scored higher than the controls. The skydivers scored higher compared to the pathological gamblers and controls on both sensation seeking subscales. Pathological gamblers scored higher than the controls on the subscale Need for Stimulus Intensity, although lower than the controls on the subscale Need for Novelty. We conclude that skydivers and pathological gamblers do not seem to differ in terms of impulsivity, but that the two groups differ in terms of sensation seeking. Skydivers are hence characterized by more sensation seeking compared to pathological gamblers. Skydiving, as opposed to pathological gambling, is not considered a psychiatric disorder, and skydiving may represent a more non-pathological way to fulfill the need for stimulus intensity.     

A psychometric investigation of the Rigorous Eating Scale

A psychometric analysis of the Rigorous Eating Scale was carried out based on data of Smead from 1986 and also from 1987 by Smead and Boyd. This 13-item scale was designed to measure hunger, deprivation, and restraint in eating style and used in both of the foregoing studies to investigate the relationship between dieting and eating style and scoring higher on measures of subclinical symptoms of anorexia and bulimia. This brief report highlights internal consistency reliability, factor structure, and item-criterion correlations. Results indicate appropriately high reliability, but inadequate factor structure. Item-criterion correlations suggest several aspects of eating style which may be important to include in similar scales of the future.
