Both researchers and clinicians, especially those working in criminal populations, have long suggested that psychopathy (or antisocial personality disorder) and schizophrenia are associated on an etiological or on some other level (e.g., Eysenck and Eysenck, 1976, 1978). Others (Hare, 1984; Hare and Harpur, 1986; Raine, 1985) argue that psychopathy is not associated (or even negatively associated) with other psychiatric disorders, including schizophrenia. To evaluate these competing positions concerning the psychopathy-schizophrenia association, 80 male prisoners remanded to a forensic psychiatric institute for assessment of their fitness to stand trial were diagnosed using both the Psychopathy Checklist (PCL; Hare, 1980, 1985a) and DSM-III Axis I and II criteria. In addition, clinical global ratings and self-report inventories were used to measure the strength of psychopathy- and schizophrenia-related traits. The results indicated that: a) although diagnoses of psychopathy (according to PCL criteria) did not have perfect specificity with respect to schizophrenia-related clinical diagnoses, the overlap was small, and the PCL scales were either not associated or negatively associated with these disorders; b) diagnoses of antisocial personality disorder (APD, according to DSM-III criteria) were generally not associated with schizophrenia-related disorders, but had lower clinical specificity than did the PCL criteria with respect to both schizophrenia-related and other psychiatric disorders; c) there was no association between psychopathy- and schizophrenia-related clinical ratings; d) psychopathy and APD diagnoses and clinical ratings were not related to scores on other standard rating scales of the severity of psychiatric symptomatology; and e) there was no difference between schizophrenic and non-schizophrenic subjects in the strength of psychopathy-related traits, and no difference between psychopaths and nonpsychopaths (or APD versus non-APD subjects) in the strength of schizophrenia-related traits. As well, self-report measures related to psychopathy and schizophrenia did not correlate with each other, or with clinical ratings of the two disorders. The results are interpreted as supporting the view that psychopathy is not positively associated with schizophrenia or with psychiatric disorder in general. The practical utility of various techniques for assessing psychopathy in forensic psychiatric populations is also discussed. / Arts, Faculty of / Political Science, Department of / Graduate

M.A. (Clinical Psychology) / In contrast to the commonly accepted notion that persons with antisocial personality disorders ore characterised by a marked absence of anxiety and depression recent studies have indicated that anxiety and depression. might indeed be found amongst some antisocial personality disorders.Where resistance to psycho-therapeutic treatment was previously ascribed to the lack of anxiety and depression in the antisocial personality disorder, its presence ...

A study of 96 students at the Islamic University of Gaza was designed to determine whether there is a difference in extroversion and neuroticism between high achieving and low achieving students, and whether there is a difference in extroversion and neuroticism due to sex. The Eysenck Personality Inventory was used to measure extroversion and neuroticism; academic achievement, high or low, was determined by students' grades at the University.The results of a two-way analysis of variance indicated that there was no significant difference in extroversion due to academic achievement, nor was there any significant difference in extroversion due to sex.Another two-way analysis of variance indicated that there was no significant difference in neuroticism due to academic achievement; however, female students did measure significantly higher than male students in neuroticism.

Specific personality characteristics have long been thought to be associated with adolescent substance abusers This study utilized the Millon Adolescent Personality Inventory (MAPI, Millon, 1982) to examine the personality styles, expressed concerns and behavioral correlates of adolescents.The subjects were 122 adolescents between the ages of 13 and 19 years old who were residents of an adolescent substance abuse treatment center. The MAPI was administered as a part of the initial assessment of each adolescent. The adolescents lived in areas that ranged from rural communities to midsize cities in a midwestern state.In this study, the dependent variable was the MAPI scores and the criterion variables were the following: gender, age, parent marital status, primary drug, secondary drug, drug use, treatment completion, and referral source. Additional subgroups studied were the following: 15-18 year old dependent males according to the primary drugs of alcohol or marijuana, and 15-18 year old females according to the primary drugs of alcohol and marijuana.Median base rate scores were calculated for the groups to reveal general personality profiles. Multivarite analyses of variance produced significant univariate Fs in the following groups: gender, parent marital status, and 15-18 year old dependent females by primary drug of choice. Results indicated that, as a whole, the group appeared to be fairly homogeneous in the personality characteristics revealed by the MAPI scores. The characteristics found mostoften in this sample were the following: moods that were unpredictable and erractic; attitudes that vacillated rapidly from unhappy to happy; relationships that ranged from ambiguous to belligerant, and affect that was irritable to disturbed. These adolescents also expressed considerable concern over family relationship issues. The Family Rapport scale was consistently the highest Expressed Concern scale. Other scales that were less pronounced, but frequently elevated were personal esteem, self-concept, and academic confidence. The most prominent elevation on the Behavioral Correlate scales was the Impulse Control scale.Similarities across groups on the scores of the MAPI scales was the most prominent finding. Scale scores in 15-18 year old dependent females group showed differences between alcohol users and marijuana users. Implications for treatment were discussed. / Department of Counseling Psychology and Guidance Services
