Validation of the Impulsive/Premeditated Aggression Scale in College Students

ABSTRACT

Impulsive (IA) and premeditated (PM) aggression reflect functions of aggressive behavior that may have differential correlates and clinical utility. The purpose of this study was to extend the use of the Impulsive/Premeditated Aggression Scale (IPAS) for characterizing aggression in a college student sample. Three hundred forty students completed the IPAS, Buss and Perry's (1992) Buss, A. H. and Perry, M. 1992. The Aggression Questionnaire. Journal of Personality and Social Psychology, 63: 452–459. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] Aggression Questionnaire (AQ), and measures of childhood maltreatment and negative life events. Principal components analyses supported reliable IA and PM factors. The degree of IA was significantly higher than that of PM. Convergent validity for the IA scale was supported with significant relationships with certain AQ scales. Implications for studying aggressive functions in this age group may inform violence prevention and treatment on college campuses.     

The Mediating Role of Peritraumatic Dissociation and Thought Control Strategies on Posttraumatic Stress in Women Survivors of Child Sexual and Physical Abuse

This study examined the link between cognitive coping strategies, type of abuse, and posttraumatic stress symptomatology. In a sample of 294 undergraduate women, several key findings emerged: (a) reported use of cognitive coping strategies significantly differed based on the type of abuse; (b) some differences in posttraumatic stress symptomatology emerged based on the type of abuse; (c) once the cognitive coping strategies were accounted for, the type of abuse was no longer associated with posttraumatic stress symptomatology. These findings suggest that peritraumatic dissociation, punishment, and social control significantly mediated the relationship between the type of abuse and posttraumatic stress symptomatology. This is important information for interventionists striving to help their clients maximize already-occurring adaptive strategies (e.g., social control).     

Domain‐specific impulsivity in school‐age children

Impulsivity is a salient individual difference in children with well‐established predictive validity for life outcomes. The current investigation proposes that impulsive behaviors vary systematically by domain. In a series of studies with ethnically and socioeconomically diverse samples of middle school students, we find that schoolwork‐related and interpersonal‐related impulsivity, as observed by teachers, parents, and the students themselves, are distinct, moderately correlated behavioral tendencies. Each demonstrates differentiated relationships with dimensions of childhood temperament, Big Five personality factors, and outcomes, such as report card grades. Implications for theoretical conceptions of impulsivity as well as for practical applications (e.g. domain‐specific interventions) are discussed.     

Time of Day Affects Episodic Memory in Older Adults*

ABSTRACT

The neuropsychological test scores of 2,030 cognitively normal older adults were examined to evaluate performance patterns as they related to time of day (TOD) at which testing was initiated. Multiple regression analyses were used to examine the association of TOD with scores on seven neuropsychological tests used in the clinical evaluation of dementia. Episodic memory performance was significantly related to TOD, while memory span and verbal fluency were not. Best performance occurred during early morning hours and late afternoon; worst performance occurred mid-day (i.e., noon). These findings may have implications for clinical assessment, the design of research on dementia, and the daily functioning of older adults.     

War exposure and post-traumatic stress as predictors of Portuguese colonial war veterans' physical health

The relationship between war exposure and post-traumatic stress disorder (PTSD) has been largely investigated but the impact of the combat experience on physical health has only recently merited attention. The authors investigated the relationship between war exposure and psychological and physical health among 350 Portuguese colonial war veterans. The role of current PTSD symptoms as a mediator of these relationships was also investigated. The results showed that 39% of the veterans met criteria for current PTSD diagnosis and psychological distress was present in half of the sample. Pain, fatigue, and sleep problems were the most reported physical symptoms and mental health and gastro-intestinal problems, the most reported illnesses. Combat exposure variables were significant predictors of current health. The results indicated that veterans with higher exposure to war trauma maintained higher current levels of psychological distress and presented more physical health problems and physical symptoms than those less exposed. Mediation analyses showed that current PTSD was a full mediator of the relationship between war exposure and physical health outcomes.
