A test of the four-factor model of impulsivity-related traits

In a recent article, Whiteside and Lynam [Person. Indiv. Diff. 30 (2001) 669] proposed a new model for understanding personality pathways to impulsive behavior. Their UPPS model maintains that there are four personality dimensions that are related differentially to impulsive behaviors: urgency, sensation seeking, (lack of) premeditation, and (lack of) perseverance. The purpose of the current study was to provide validation for this model and to test some of the specific hypotheses offered by Whiteside and Lynam. The sample used in this study consisted of 481 individuals who completed mailed surveys at age 20 and an in-depth laboratory protocol at age 21. Zero-order correlations and multiple regression analyses were used to examine the relations between the four personality traits and various forms of externalizing behaviors, several types of internalizing psychopathology, and intelligence. Results revealed that the four traits were differentially related to various behaviors and forms of psychopathology consistent with many of Whiteside and Lynam's predictions. Therefore, the UPPS model does appear to offer a novel and useful way of understanding behaviors and forms of psychopathology considered to be characterized by some form of impulsivity.     

Internet use and social support in women with breast cancer.

Many Web sites offer information to breast cancer patients, who are increasingly using these sites. The authors investigated the potential psychological benefits of Internet use for medical information by breast cancer patients. Of the 251 women approached, 188 were successfully interviewed (74.9%). Forty-two percent used the Internet for medical information related to breast health issues and did so for an average of 0.80 hr per week. The Interpersonal Support Evaluation List and the UCLA Loneliness Scale, with results controlled for covariates, showed that Internet use for breast health issues was associated with greater social support and less loneliness than Internet use for other purposes or nonuse. Breast cancer patients may obtain these psychological benefits with only a minimal weekly time commitment.     

The Impact of Adolescent Suicide on Siblings and Parents: A Longitudinal Follow-Up

The psychiatric sequelae of loss of a family member to suicide were evaluated in parents and siblings of adolescent suicide victims and controls, who were followed up to 3 years after the suicide. Siblings did not show an increased risk for the development of depression, posttraumatic stress disorder (PTSD), or other conditions over the course of follow-up, despite showing a prolonged elevated level of grief symptomatology. Mothers showed an increased rate of recurrence of depression over follow-up, whereas fathers did not show an increased incidence of disorder compared to fathers of controls. The interrelationship of bereavement and depression for siblings, parents, and others exposed to suicide is discussed.     

Boosting the Potency of Resistance: Combining the Motivational Forces of Inoculation and Psychological Reactance

The efficacy of inoculation theory has been confirmed by decades of empirical research, yet optimizing its effectiveness remains a vibrant line of investigation. The present research turns to psychological reactance theory for a means of enhancing the core mechanisms of inoculation—threat and refutational preemption. Findings from a multisite study indicate reactance enhances key resistance outcomes, including: threat, anger at attack message source, negative cognitions, negative affect, anticipated threat to freedom, anticipated attack message source derogation, perceived threat to freedom, perceived attack message source derogation, and counterarguing. Most importantly, reactance‐enhanced inoculations result in lesser attitude change—the ultimate measure of resistance.     

An investigation of everyday prospective memory

Prospective memory, remembering to carry out one’s planned activities, was investigated using a naturalistic paradigm. Three experiments, with a total of 405 participants, were conducted. The goal was to demonstrate that the cognitive processing underlying successful everyday prospective remembering involves components other than mere “memory.” Those components are probably best represented as individual differences in various cognitive capacities. More specifically, metamemory, attentional capacities, and planning processes that reprioritize intentions according to the demands of everyday life may determine how people actually accomplish the plans they establish for themselves. The results of these experiments suggest that researchers interested in the topic will have to contend with a multidimensional set of factors before any comprehensive understanding of prospective remembering can be realized.
