Background: Over-reporting of posttraumatic stress disorder (PTSD) symptoms has been observed in some cases, following a motor vehicle accident (MVA). It has been suggested, however, that these are cases of underdiagnoses in primary care settings. The current study focused on people with PTSD in primary care settings who experienced an MVA and do not seek psychiatric help.

Although the connection between smoking and individual differences has been recently recognized, the relationship between narcissistic personality traits and cigarette smoking has received less attention. The notion that personality traits can be associated with addictive behavior is influential in clinical practice. However, questions remain about specific interactions between smoking and personality characteristics that need empirical support to substantiate this hypothesis.

Background: Research on the association between decision making and inhibition abilities has exhibited fundamental controversies. Some authors claim that inhibition abilities are an integral part of the decision-making process, whereas others suggest that the decision-making process does not operate in close association with inhibition abilities. Can gender explain variations in risky decisions via inhibition influences?

Purpose: The purpose of the present study was to explore the associations between response inhibition, reflection inhibition, interference inhibition, and decision-making processes in men and women.

Pathological gamblers (PGs) perform differently on neurocognitive tests than do healthy controls (HC). The aim of this study was to assess "waiting ability" - a major components of inhibition control-using a modified Stop Signal Task (SST) in a population of male PGs (N=55), and HCs (N=53). Results indicated no differences between PGs and HCs in reaction times, intra-individual response variability, or number of false alarms and misses.

Background: According to previous studies, one of the common problems of everyday life of persons with tattoos is risky behavior. However, direct examination of the decision making process, as well as factors which determine women's risk-taking decisions to get tattoos, have not been conducted. This study investigates whether risk taking decision-making is associated with the self-assessment impulsiveness in tattooed women.

There is growing evidence that individual differences among patients with major depressive disorder (MDD) on psychological and demographic measures may predict the therapeutic response to selective serotonin reuptake inhibitors (SSRIs). In this retrospective chart review, 108 outpatients with current major depressive episodes were treated with citalopram, paroxetine, or fluvoxamine. The Hamilton Depression Rating Scale and the Minnesota Multiphasic Personality Inventory-2 were administered before and after 8 weeks of SSRIs treatment.

Background: Pathological gambling is classified as an impulse control disorder in the DSM-IV-TR; however, few studies have investigated the relationship between gambling behavior and impulsive decision-making in time-non-limited situations.

Methods: The subjects performed the Matching Familiar Figures Test (MFFT). The MFFT investigated the reflection-impulsivity dimension in pathological gamblers (n = 82) and demographically matched healthy subjects (n = 82).

Previous neuropsychological studies demonstrated various deficits of impulse control in pathological gamblers (PGs). However, there are limited data available on response-inhibition impairment among PGs. The present study attempted to assess response inhibition in untreated PGs (N=83), in comparison with normal subjects (N=84).

In this preliminary investigation of variability of responses on the Lüscher Color Test, subjects were 567 volunteers administered the test twice with a 10-min. interval between them. Two hypotheses were tested: (a) that variability of responses attests to the personality of the respondent (tested by the relations of variability and MMPI scale scores), and (b) variability of responses is based on learning the test's content.
