Traumatic events have predicted depressive symptoms. Despite this consensus, it remains unclear as to whether the relationship between trauma and depression is consistently mediated by a negative cognitive schema, such as low self-esteem, or whether trauma influences mood independently of low self-esteem. This study tested these relationships while considering depressive symptom types. One hundred thirty-two students reported the number of traumatic events experienced and self-esteem and depression levels. Results indicated 2 depressive symptom types: "cognitive-affective" and "somatic." Structural Equation Modeling tested an unmediated path from trauma to depressive symptoms and a path mediated by self-esteem. Results supported the unmediated relationship between trauma and "cognitive-affective" depressive symptoms, and did not support mediation by self-esteem. Findings are discussed in view of a dimensional rather than categorical approach to depression, and in consideration of alternative symptom clusters resulting from trauma in addition to those captured by posttraumatic stress disorder.

Whiteside and Lynam (Whiteside, S. P., & Lynam, D. R. (2001). The Five Factor Model and impulsivity: Using a structural model of personality to understand impulsivity. Personality and Individual Differences, 30, 669-689) clarified the multifaceted nature of impulsivity by identifying four distinct facets of self-reported impulsive behaviors: urgency, (lack of) premeditation, (lack of) perseverance, and sensation seeking. Building on work by Bechara and Van der Linden (Bechara, A., & Van der Linden, M. (2005). Decision-making and impulse control after frontal lobe injuries. Current Opinion in Neurology, 18, 734-739), the main objective of this study was to investigate the hypothesis that perseverance and urgency map onto the two distinct inhibitory functions distinguished by Friedman and Miyake (Friedman, N. P., & Miyake, A. (2004). The relations among inhibition and interference control functions: A latent-variable analysis. Journal of Experimental Psychology: General, 133, 101-135): prepotent response inhibition and resistance to proactive interference. Participants (N=126) completed the UPPS Impulsive Behavior Scale and three tasks: a recent-negatives task to assess proactive interference in working memory, and two Go/No-Go tasks at different paces, the slower of which also assessed task-unrelated thoughts (TUTs). Consistent with the hypothesis, TUTs were positively correlated with lack of perseverance, and multiple regressions revealed that urgency was specifically related to errors in prepotent response inhibition, and lack of perseverance to errors due to difficulties overcoming proactive interference.

According to Gray's Reinforcement Sensitivity Theory (RST; Gray, 1982), personality results from the interaction of three major systems: a Behavioural Activation System (BAS), a Behavioural Inhibition System (BIS) and a Fight/Flight System (FFS). Based on this model, Torrubia, Avila, Molto, and Caseras (2001) developed an instrument, the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), which assesses the two major systems that explain individual differences in sensitivity and reactions to punishing and rewarding stimuli. In the present study, we have proposed a short version of the SPSRQ, based on O'Connor, Colder, and Hawk's (2004) findings. To this end, 360 participants were screened using the French translation of a short version of the SPSRQ. Confirmatory factor analysis showed that a two-factor model has acceptable fit. Moreover, the results indicated that there was very good internal reliability for both the sensitivity to reward and sensitivity to punishment scales. © 2008 Elsevier Ltd. All rights reserved.

Cigarette smoking is a very important health problem and represents the largest preventable risk factor for premature death in developed countries. A considerable body of research indicates that impulsivity is a central etiological concept in many theoretical models of tobacco addiction. The aim of this study is to analyse which dimensions of impulsivity are related to cigarette craving. To this end, 40 undergraduate psychology students were screened using the revised Questionnaire on Smoking Urges (QSU-12) and the French adaptation of the UPPS Impulsive Behavior Scale (UPPS). This scale identifies four distinct components associated with impulsive behaviour: urgency, lack of premeditation, lack of perseverance, and sensation seeking. The results showed that urgency is a significant predictor of tobacco cravings, while depression and anxiety are not. [less ▲]

Several authors have studied the risks arising from the growth in mobile phone use (e.g. large debts incurred by young people, banned or dangerous use of cellular phones). The aim of this study is to analyse whether impulsivity, which has often been related to various forms of addictive behaviours, is associated with massive use of and dependence on the mobile phone. In this study, 108 female undergraduate psychology students were screened using a questionnaire evaluating actual use of and perceived dependence on the mobile phone, and with the French adaptation of the UPPS Impulsive Behavior Scale. This scale identifies four distinct components associated with impulsive behaviour: Urgency, lack of Premeditation, lack of Perseverance, and Sensation Seeking. The results showed that a relationship can be established between the use of and perceived dependence on the cellular phone and two facets of impulsivity: Urgency and lack of Perseverance.
