Effects of live exposure on symptoms of posttraumatic stress disorder: the role of reduced behavioral avoidance in improvement 总被引:3,自引:0,他引:3
Although the effectiveness of cognitive-behavioral treatment in posttraumatic stress disorder (PTSD) is well established, few studies examined its effects on individual PTSD symptoms and possible mechanisms of improvement in symptoms. In a previous randomized controlled study [Ba?og lu, M., Salciog lu, E., Livanou, M., Kalender, D., & Acar, G. (2005). Single-session behavioral treatment of earthquake-related posttraumatic stress disorder: A randomized waitlist controlled trial. Journal of Traumatic Stress, 18, 1-11] a single session of behavioral treatment involving self-exposure instructions was highly effective in reducing earthquake-related PTSD. In the present study we examined the effects of treatment on each PTSD symptom and which symptoms improved early in treatment. Because the intervention focused solely on behavioral avoidance, we hypothesized that avoidance would be the first symptom to change and that reduction in avoidance would generalize to all other symptoms. The results showed significant between-groups treatment effect on only behavioral avoidance early in treatment (week 6). At 6 months post-treatment recovery rates ranged from 60% to 89% for 15 PTSD symptoms, including the numbing symptoms. Lack of improvement in avoidance was associated with lack of improvement in 12 symptoms. The critical process in recovery thus appeared to be increased sense of control associated with reduction in avoidance. These findings imply that live exposure to fear cues designed to enhance sense of control might be sufficient for recovery from PTSD. 相似文献

Managerial modes of influence and counterproductivity in organizations: a longitudinal business-unit-level investigation 总被引:1,自引:0,他引:1
The authors studied the effect of 3 modes of managerial influence (managerial oversight, ethical leadership, and abusive supervision) on counterproductivity, which was conceptualized as a unit-level outcome that reflects the existence of a variety of intentional and unintentional harmful employee behaviors in the unit. Counterproductivity was represented by an objective measure of food loss in a longitudinal study of 265 restaurants. After prior food loss and alternative explanations (e.g., turnover, training, neighborhood income) were controlled for, results indicated that managerial oversight and abusive supervision significantly influenced counterproductivity in the following periods, whereas ethical leadership did not. Counterproductivity was also found to be negatively related to both restaurant profitability and customer satisfaction in the same period and to mediate indirect relationships between managerial influences and distal unit outcomes. 相似文献

Two experiments were carried out to find within-subject consistencies as well as individual differences in a choice situation involving achievement persistence. Four volunteers, two men (21 and 23 years old) and two women (21 and 22 years old) were exposed twice, with a 1-mo. interval, to a filling-patterns task, to evaluate their choices for two options. For one option, task-time and outcomes for every response were constant. For the other option, task-time decreased in correlation with an increase in earnings for every response. Analyses showed reliable profiles for three of the four subjects when percent of responding to each option was compared in independent experiments. Results are discussed in terms of interactive styles. 相似文献

Cognitive scientists distinguish between automatic and controlled mental processes. Automatic processes are either innately involuntary or become automatized through extensive practice. For example, reading words is a purportedly automatic process for proficient readers and the Stroop effect is consequently considered the "gold standard" of automated performance. Although the question of whether it is possible to regain control over an automatic process is mostly unasked, we provide compelling data showing that posthypnotic suggestion reduced and even removed Stroop interference in highly hypnotizable individuals. Drawing on a large sample of highly hypnotizable participants, we examined the effects of suggestion on Stroop performance both with and without a posthypnotic suggestion to perceive the input stream as meaningless symbols. We show that suggestion administered to highly hypnotizable persons significantly reduced Stroop interference and derailed a seemingly automatic process. 相似文献

The goal of this study was to develop a simple, easy, and quick self-report measure, the Lupus Symptom Inventory (LSI), designed
to evaluate subjective symptoms of Systemic Lupus Erythematosus (SLE). The internal consistency of the LSI was tested, as
well as its concordance with physician reports and serological indicators of disease activity by evaluating the self-reports
of 46 patients with SLE who completed the LSI daily for a one-month period. Throughout this one-month period, parameters of
serological activity and routine medical check-up were obtained. The results showed a high internal consistency of the LSI,
with a Cronbach alpha of .86. Additionally, a contingency analysis showed agreement between medical report and patient self-report
on the same day for six of seven lupus symptoms (difficulty breathing (p < .004), joint pain (p < .001), loss of appetite (p < .003), general malaise (p < .005), fatigue (p < .005), and skin rash (p < .018)) but not for abdominal symptoms. Finally, differences were found between LSI scores of patients with high versus
low serological activity (χ2(1) = 5.302; p < .021), with the former presenting higher LSI scores than the latter. These results show that the LSI may be a reliable
and valid instrument for evaluating the subjective symptoms of the disease as well as its fluctuations. 相似文献

Inspired by attachment theory, the authors tested a series of theoretically derived predictions about connections between attachment working models (attachment to one's parents assessed by the Adult Attachment Interview; M. Main & R. Goldwyn, 1994) and the effectiveness of specific types of caregiving spontaneously displayed by dating partners during a stressful conflict-resolution discussion. Each partner first completed the Adult Attachment Interview. One week later, each couple was videotaped while they tried to resolve a current problem in their relationship. Trained observers then rated each interaction for the degree to which (a) emotional, instrumental, and physical caregiving behaviors were displayed; (b) care recipients appeared calmed by their partners' caregiving attempts; and (c) each partner appeared distressed during the discussion. Individuals who had more secure representations of their parents were rated as being more calmed if/when their partners provided greater emotional care, especially if they were rated as more distressed. Conversely, individuals who had more insecure (dismissive) representations of their parents reacted more favorably to instrumental caregiving behaviors from their partners, especially if they were more distressed. The broader theoretical implications of these findings are discussed. 相似文献

In the last few years, many researchers have studied the presence of common dimensions of temperament in subjects with symptoms of anxiety. The aim of this study is to examine the association between temperamental dimensions (high negative affect and activity level) and anxiety problems in clinical preschool children. A total of 38 children, ages 3 to 6 years, from the Infant and Adolescent Mental Health Center of Girona and the Center of Diagnosis and Early Attention of Sabadell and Olot were evaluated by parents and psychologists. Their parents completed several screening scales and, subsequently, clinical child psychopathology professionals carried out diagnostic interviews with children from the sample who presented signs of anxiety. Findings showed that children with high levels of negative affect and low activity level have pronounced symptoms of anxiety. However, children with anxiety disorders do not present different temperament styles from their peers without these pathologies. 相似文献

The aim of the present study was to validate a reduced Spanish version of the Negative Acts Questionnaire (NAQ; Einarsen & Raknes, 1997). This instrument, which has been widely used in various studies, was developed to measure workplace bullying. Two samples, the first comprising 352 employees from 11 organizations, and the second comprising victims of bullying who were recruited from 15 Spanish associations against bullying, participated in the study. Exploratory factor analysis conducted with the data from the first sample revealed a two-factor solution that accounted for 63.3% of the total variance. The data from the second sample were used for confirmatory factor analyses to compare three structure models of the NAQ (one factor, two independent factors, and two correlated factors). The results indicate that the correlated two-factor model provided the best fit to the data (chi2/df = 2.1, CFI = .93, GFI = .95, RMR = .04, RMSEA = .06, AIC = 215.4). Reliability analysis showed that this 14-item Spanish version had high internal consistency. Significant correlations between the NAQ and its dimensions and diverse health and perceived stress scales were found, which provided evidence of construct validity. Taken conjointly, the results of this study support the use of the Spanish version of the reduced NAQ in future research. 相似文献

Priming of affective word evaluation by pictures of faces showing positive and negative emotional expressions was investigated in two experiments that used a double task procedure where participants were asked to respond to the prime or to the target on different trials. The experiments varied between-subjects the prime task assignment and the prime-target interval (SOA, stimulus onset asynchrony). Significant congruency effects (that is, faster word evaluation when prime and target had the same valence than when they were of opposite valence) were observed in both experiments. When the prime task oriented the subjects to an affectively irrelevant property of the faces (their gender), priming was observed at SOA 300 ms but not at SOA 1000 ms (Experiment 1). However, when the prime task assignment explicitly oriented the subjects to the valence of the face, priming was observed at both SOA durations (Experiment 2). These results show, first, that affective priming by pictures of facial emotion can be obtained even when the subject has an explicit goal to process a non-affective property of the prime. Second, sensitivity of the priming effect to SOA duration seems to depend on whether it is mediated by intentional or unintentional activation of the valence of the face prime. 相似文献
