Self-reported anxiety in children and adolescents: a three-year follow-up study

Anxiety may be more transient in children and adolescents than in adults. The present study involves a longitudinal design enabling the investigation of the continuity/discontinuity of self-reported anxiety in children and adolescents. A sample of 68 children was followed over 3 years. Results indicate that, on the whole, self-reported anxiety decreased over time. This was true for overall anxiety and its sub-types, with the exception of social concerns/concentration, which did not decrease over time. Consistent with past research involving normal fear, girls and younger children were found to score higher on anxiety than boys and older children did. However, those groups scoring higher at inception also demonstrated the most marked decreases over the 3-year period. In addition to the changes found over time, the data indicated continuity in anxiety such that levels of anxiety at inception were significant predictors of follow-up anxiety, although only a small amount of variance was shared. The authors concluded that adult models of anxiety cannot be applied to youth and that future research should investigate the contribution of contextual factors to the development of anxiety in children.     

Manager psychopathy,trait activation,and job performance: a multi-source study

Individuals high in psychopathy are often portrayed as more likely to display antisocial behaviour in the workplace and to demonstrate lower job performance. Current research on the impact of trait psychopathy in the workplace is characterized by divergent findings of moderate versus weak effects. We aim to address two potential causes for these discrepant results: mono-source bias and the failure to consider the situational factors that can activate psychopathy. In addition, we used the triarchic model of psychopathy, which incorporates the meanness dimension, a conceptualization of predatory orientation. Our multi-source design disconfirmed concerns that the effects of psychopathy are merely based on mono-source bias. More specifically, we found that the predatory orientation of managers high in psychopathy and especially high in the trait of meanness was behaviourally activated by high levels of ascendency prospects and prospects for income increases. High psychopathy, mediated by consideration towards subordinates and moderated by high ascendency prospects and high prospects for income increases, was associated with low supervisory job performance ratings. Implications and limitations of our findings and directions for future research are discussed.     

The Ego Impairment Index and schizophrenia: a validation study.

This study is an extension of our work on a new scale, the Ego Impairment Index (EII; Perry & Viglione, 1991). The index is theoretically based on Beres's (1956) model of ego assessment and was empirically developed on a sample of melancholic, depressed outpatients, diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (3rd ed. [DSM-III]; American Psychiatric Association, 1980). The EII is derived from the Rorschach Inkblot Test and offers a single composite score of ego impairment. This study validates the use of the EII with a heterogeneous sample of schizophrenic patients. In support of the trait-like characteristics of the scale, the EII continues to be expressed as a single factor, with a correlation of .98 when comparing the original factor derived from a melancholic population with this sample of schizophrenic patients. Significant correlations were also found between the EII and other clinical indices, including the Magical Ideation Scale, the Schizophrenia Index, and the Minnesota Multiphasic Personality Inventory (MMPI). Finally, the EII was found to differentiate between a paranoid subgroup and a mixed undifferentiated/disorganized subgroup who theoretically have more ego impairment. These results offer support for the use of the EII as an empirical means of quantitatively and qualitatively assessing thought disorder within a theoretical framework. Further research is needed to understand the application of the EII across different diagnostic groups and its relationship to other indices of psychological disturbance.     

The anxiety thermometer: a validation study

The aim of our study was to provide validation and reproducible data for the anxiety thermometer. This thermometer is either a continuous or a 10-point Likert-type scale on which subjects are asked to rate their anxiety feelings at a particular moment. It is a quick way to measure state-anxiety. As a validation criterion the State-Trait Anxiety Inventory (STAI) A-State scale was used. To test the reproducibility of the thermometer, a test-retest correlation coefficient was calculated, with a retrospective second thermometer score. The ego-threatening situation used was a written examination. Two experiments were carried out during different examination conditions. The data consistently indicated that the validity and reproducibility of the anxiety thermometer is fair (correlation coefficients between .60 and .78) In the second study, the possible influence of two factors on the retrospective scores were additionally tested.     

Assessing the basic traits associated with psychopathy: development and validation of the Elemental Psychopathy Assessment

A new self-report assessment of the basic traits of psychopathy was developed with a general trait model of personality (five-factor model [FFM]) as a framework. Scales were written to assess maladaptive variants of the 18 FFM traits that are robustly related to psychopathy across a variety of perspectives including empirical correlations, expert ratings, and translations of extant assessments. Across 3 independent undergraduate samples (N = 210-354), the Elemental Psychopathy Assessment (EPA) scales proved to be internally consistent and unidimensional, and were strongly related to the original FFM scales from which they were derived (mean convergent r = .66). The EPA scales also demonstrated substantial incremental validity in the prediction of existing psychopathy measures over their FFM counterparts. When summed to form a psychopathy total score, the EPA was substantially correlated with 3 commonly used psychopathy measures (mean r = .81). Finally, in a small male forensic sample (N = 70), the EPA was significantly correlated with scores on a widely used self-report psychopathy measure, disciplinary infractions, alcohol use, and antisocial behavior. The EPA provides an opportunity to examine psychopathy and its nomological network through smaller, more basic units of personality rather than by scales or factors that blend these elements.     

Construct validity of psychopathy in a community sample: a nomological net approach.

The construct validity of psychopathy was examined within a sample of 326 male and female university students. The interpersonal circumplex served as a nomological net for the examination of convergences between psychopathy measures and convergent and discriminant validity with a measure of personality disorders was examined using a matrix approach. Measures included: (a) Antisocial scale of the Personality Assessment Inventory (Morey, 1991); (b) Self-Report Psychopathy scale (Hare, 1991); (c) Psychopathic Personality Inventory (Lilienfeld & Andrews, 1996); (d) Personality Diagnostic Questionnaire-4 (Hyler, 1994); and (e) Interpersonal Adjective Scales Revised-Big 5 (Trapnell & Wiggins, 1991). Results indicated (a) substantial convergence between psychopathy measures; (b) high convergent validity between psychopathy measures and antisocial personality disorder; and (c) high discriminant validity from other personality disorders. The prevalence of psychopathy within this non-forensic sample is also discussed.     

Self-reported psychological stress and the risk of breast cancer: a case-control study

The aim of this study was to examine the relationship between severe life events and breast cancer risk. This study was based on a case-control examination of 858 Polish invasive breast cancer cases and 1085 controls matched for age and place of residence. Data on life events, sociodemographic characteristic, reproductive factors, family history of breast cancer, current weight and height, and lifestyle habits were collected between January 2003 and May 2007 using a self-administered questionnaire. Odds ratios with 95% confidence intervals were estimated as the measure of the relationship between life event stress and breast cancer risk using unconditional logistic regression analyses. After adjustment for potential breast cancer risk factors, women with four to six individual major life events had 5.33 times higher risk for breast cancer, compared with those in the lowest quartile. Similarly, women with a lifetime life change score greater than 210 had about 5 times higher risk compared to women with corresponding scores in the range 0-70. Several life events (death of a close family member, personal injury or illness, imprisonment/trouble with the law, retirement) were significantly associated with breast cancer risk. These findings suggest that major life events can play an important role in the etiology of breast cancer.     

Levels of psychopathy and its correlates: a study of incarcerated youths in three states

We report the results of a study on psychopathy and its correlates among 203 youths incarcerated in residential commitment programs in Pennsylvania, Ohio, and Delaware. Latent class analysis of the psychopathy data identified three classes of youths: low psychopathy, moderate psychopathy, and high psychopathy. Significant differences were found among the three groups in regard to their criminal thinking, delinquency, experience of stressful events, family relationships, and drug use. Conduct disordered, psychopathic youths were the most troubled among the youths studied.     

The problems of internal validation without a theoretical context: the different conceptual underpinnings of psychopathy and the disruptive behavior disorder criteria

G. L. Burns (2000) has concluded that the Psychopathy Screening Device's content is limited because it contains items that overlap with criteria for several disorders in the Diagnostic and Statistical Manual of Mental Disorders (DSM). The problem with G. L. Burns's analysis is that it was conducted without an adequate understanding or specification of the conceptual underpinnings of either the construct of psychopathy or the constructs assessed by the DSM criteria. This reply attempts to clarify these conceptual frameworks to illustrate that to judge the adequacy of the content of a measure of psychopathy by comparing it with DSM criteria is inconsistent with the differing theoretical frameworks underlying these classification systems. Forcing measures of psychopathy to be designed around DSM criteria leads to inadequate measures of psychopathy and can limit advances both in our understanding of developmental precursors to psychopathy and in the classification of DSM disorders.     

Self-reported versus behavioral self-handicapping: empirical evidence for a theoretical distinction.

The present study was an investigation of how Ss would respond when given 2 self-handicapping options, 1 behavioral (withdrawal of practice effort) and 1 self-reported (reporting high levels of stress). Ss anticipating a diagnostic test of intellectual ability were given different instructions regarding the effects of stress and practice on test performance. Ss were told that (a) stress only, (b) practice only, (c) both stress and practice, or (d) neither stress nor practice affected test scores. Ss were then given the opportunity to self-report a handicap on a stress inventory and to behaviorally self-handicap by failing to practice before the test. High self-handicapping men and women showed evidence of self-reported handicapping, but only high self-handicapping men behaviorally self-handicapped. However, when both self-handicaps were viable, both high self-handicapping men and women preferred the self-reported over the behavioral self-handicap.     

Self-reported competences and problems in Spanish adolescents: a normative study of the YSR

The aim of the study was to provide a standardization of self-reported competences and emotional/behavioural problems in Spanish adolescents, using the Achenbach's Youth Self-Report (YSR), and to compare our results to those from other countries. The YSR was completed by 2822 adolescents aged 11-18 years, recruited from secondary schools in two regions of Spain. There were significant differences in Total behaviour problems and in most problem scales in boys and girls, scoring boys higher on externalizing syndromes, whereas girls score higher on internalizing syndromes . Males' mean scores were higher than females' scores for social competence. Age effects also showed significant differences with respect to internalizing problems, thought problems, social problems and depression. Cut-off points based on the 90th and 98th percentile developed from this sample are presented for the competences and the problem scales. To test the overall range of variations across cultures, comparisons were made between broad band and narrow band measures of the YSR in Spanish adolescents and those from other countries. Gender differences in the YSR were similar to those found across different cultures; there is a consistent trend to increase behavioural problems with age; and social competence seem to be a relevant protective factor against behavioural problems.     

Screening for adolescent psychopathy among at-risk youth: initial validation of the Survey of Attitudes and Life Experiences

Psychopathic youth pose special challenges to clinicians in providing effective treatment and safe management. Because comprehensive assessments of psychopathy are time intensive and require specialized training, programmatic research is needed to develop time-efficient and useful screens that eliminate from further consideration acting-out adolescents who are unlikely to be psychopathic. The clinical utility of the Survey of Attitudes and Life Erperiences as a psychopathy screen was investigated by combining three samples of adolescent offenders (total N = 223). Its primary purpose was the identification of nonpsychopaths who were distinguished from adolescents in either the mixed or psychopathic ranges. A Psychopathy Screen (PS) Scale was developed with 24-item (PS-24) and 11-item (PS-11) versions. Both appeared moderately effective in excluding nonpsychopaths from further evaluation. Preliminary data on response styles suggest that these scales are not susceptible to social desirability.     

The Aggression Questionnaire: a validation study in student samples

The goal of this study was to examine the psychometric properties of the Aggression Questionnaire (AQ) in Spain. The AQ is a 29-item instrument designed to measure the different dimensions of the hostility/anger/aggression construct. It consists of 4 subscales that assess: (a) anger, (b) hostility, (c) verbal aggression, and (d) physical aggression. In Study 1, reliability, construct validity, and convergent validity were evaluated in a group of 384 male and female university students. Test-retest reliability was evaluated using a group of 154 male and female university students. The results of the factor analysis were similar to the scale structure claimed for this instrument. The subscales also showed internal consistency and stability over time. The AQ and its subscales were also compared with the scales and subscales of the Spielberger State-Trait Anger Expression Inventory (STAXI), the Cook-Medley Hostility Scale (Ho), the Buss-Durkee Hostility Inventory (BDHI), and the Jenkins Activity Survey-Form H (JASE-H). The results show that the AQ evaluates some aspects of anger, such as Anger-Trait and Anger-Out, rather than other elements, such as Anger-In or Anger-State. In Study 2, two new male groups were used to evaluate the criterion validity of the AQ: 57 prison inmates and 93 university students, finding that this instrument discriminated between the scores obtained by common offenders and university students.     

Arousability and stress-related physical symptoms: a validation study of Coren's arousal predisposition scale.

Coren's Arousal Predisposition Scale was validated against 249 college students' self-ratings of stress-related physical symptoms and an item that assessed general level of health. As we predicted, the 126 high-arousability subjects were substantially higher in mean stress-related symptoms score and lower in general health than the 123 peers low in arousability. These data suggest that the Arousal Predisposition Scale may be a useful instrument in the study of human stress.     

Self-reported effects of dreams on waking-life creativity: an empirical study

The authors studied the self-rated effect of dreams on creativity in participants who were not selected for creative abilities. Students (N = 444) and online respondents (N = 636) answered a questionnaire about dreams and creative dreams. In addition, the students completed several personality measures and creativity scales. Results indicated that dreams that stimulated waking-life creativity played a considerable role in the lives of ordinary people (about 8% of all dreams). Examples reported by the online participants fell into 4 categories: (a) dream images used for art, work, or similar areas; (b) dreams that solved a problem; (c) dreams that provided the impetus to do something that the dreamer otherwise had difficulty doing; and (d) dreams containing emotional insights. The main factors influencing frequency of creative dreams were dream recall frequency and the thin boundaries personality dimension. Future researchers should use diary techniques to study the effects of dreams on waking life and should develop techniques to increase the frequency of creative dreams that might be valuable as aids for people in creative jobs.     

Convergence and divergence among self-report psychopathy measures: a personality-based approach

The study examined, in a sample of 346 undergraduates, the convergence and divergence of three self-report measures of psychopathy; the Psychopathic Personality Inventory (Lillienfeld & Andrews, 1996), the Self-Report Psychopathy scale (Hare, Harpur, & Hemphill, 1989), and the Five Factor Psychopathy Index (Miller, Lynam, Widiger, & Leukefeld, 2001). Measures demonstrated strong convergence at the total score level, but weak convergence at the factor level. Correlations with domains and facets of the NEO Personality Inventory-Revised (Costa & McCrae, 1992) provided personality parsings of each measure. Across measures, psychopathy was composed of low Agreeableness, low Conscientiousness and a blend of high and low facets of Neuroticism and Extraversion. Divergence among subscales was due to differences in personality characteristics assessed. Additionally, the potential moderating effects of sex were also examined, but very few were identified. Implications of these results and future directions are discussed.     

Self-reported arousal: further development of a multi-factorial inventory

Abstract.— The previously presented (Bohlin & Kjellberg, 1973) inventory of self-reported arousal, which contained four factor analytically derived scales, was further developed in the following way. First, the original factor pattern was cross-validated. Second, a new response scale was constructed which proved to be superior to the old one. Third, the inventory was extended with new items and factor analysis applied to this new inventory. From the model of phenomenological arousal advanced by Bohlin & Kjellberg (1973) six factors were hypothesized and it was shown that a similar solution could be obtained with the extended inventory. Finally, this six-factor pattern was cross-validated and six scales, labelled Sleep-Wakeful-ness, Energy, Stress, Irritation, Euphoria, and Concentration, were constructed.
