Cognitive training in schizophrenic diseases

The comparison of an experimental group of schizophrenic patients undergoing cognitive training with a control group was tested for significance over a total of 23 psychometric features, using the test known as t-distribution or "Students distribution". Cognitive training results in varying degrees of improvement in the various parameters. Uncharacteristic schizophrenic basic disorders remitted significantly, and there was improvement in activity of intention, BP/RS sum score, and the BP/RS factors of anxiety/depression, anergy, and activation. The NOSIE factors of manifest psychosis, irritability, and depression remitted, and social interest improved. From the psychological data it can be concluded that cognitive training can help improve, in particular, cognitive adjustment and adaptability, and the organisation of complex societal conditions.     

Cognitive appraisal,vulnerability and coping: An integrative analysis of appraisal and coping mechanisms

Research on stress has generally concluded that stress occurs within the person as a result of their cognitive appraisal of experience. However although a number of cognitive theories of emotion exist, an integrative analysis of cognitive appraisal and vulnerability to stress has not been produced. This report contains two studies. Study 1 draws together the major variables identified in the literature in an analysis of their power to differentiate between a clinical sample (n = 48), a self-help group (n = 54), and a control sample (n = 509). The analysis shows that achievement motivation, attributional style, problem-solving style, emotional reactivity; hopelessness, perceived control and perceived social support are significant discriminators. In a second study the relationship between these variables and aspects of life stress, work stress, life satisfaction, depression, anxiety, and positive affect were investigated. Again the data support an explanatory role for these variables. The suggestion is that these variables can be utilized in an integrative model of cognitive appraisal in the stress process to guide intervention.     

Cognitive appraisal and attributional correlates of depressive symptoms in children

This study examined differences in cognitive appraisal and causal attributions in response to a task among schoolchildren reporting high and low depressive symptomatology. From a sample of 361 fifth- and sixth- grade students, 72 children were classified as depressed or nondepressed on the basis of their scores on the Children's Depression Inventory. They were then presented with modified Picture Arrangement problems from the WISC- R and questioned about their performance. Pretask expectations, evaluations, and future expectations of performance for the self and that of same- aged peers were assessed, as well as causal explanations for solvable and unsolvable problems. Despite similar performance, the depressed group of children provided lower evaluations for themselves than for others on all three measures of self- appraisal, whereas the nondepressed group did not show this tendency. Further, the attribution results indicated that the two groups differed in their explanations for failure, with the depressed group emphasizing the importance of ability in failure and the nondepressed group emphasizing factors other than ability. Overall, the results provide support for the presence of negative cognitions and self- defeating attributional style among depressed relative to nondepressed children, as well as pointing to the importance of social comparison processes in depression.This research was supported by studentships to Nancy Meyer from the Manitoba Health Research Council and subsequentlv from the Social Sciences and Humanities Research Council, and by a grant to Dennis Dyck from the Natural Sciences and Engineering Research Councel of Canada.

Occupational stress management: A review and appraisal

Published and unpublished studies evaluating the merits of occupational stress management are reviewed. Worksite stress management studies are compared along dimensions of type of work group, programme orientation and format, stress management methods, non-specific effects, and long-term maintenance of skills and benefits. Although studies differ widely on these dimensions and too few studies have been conducted to state unequivocally general conclusions, worksite stress management programmes appear to offer promise for helping workers cope with stress and exert greater control over physiological and psychological systems which are reactive to stressors. Troublesome issues in this young research area are noted and future research needs are enumerated. Finally, the advantages and potential disadvantages of worksite stress management programmes are described.     

Cognitive appraisal mediating relationship between social anxiety and internet communication in adolescents

Research suggests that people with high social anxiety trait may be more inclined to interact through computer-mediated communication (CMC). The psychological underpinnings of this inclination however remained unclear. The present research thus examines if cognitive appraisal bias (i.e. heighten estimation of social risk and deflated self-efficacy) would mediate the relationship between social anxiety and one’s perception of CMC attributes, contributing to a differential pattern of responses in CMC use. Four hundred and ten adolescents aged 12-18 years completed a set of self-reported measures tapping social anxiety trait, cognitive appraisals, perception of CMC attributes, and pattern of CMC social responses. Structural equation modeling lent support to the mediating role of the cognitive appraisal factors. Those with higher social anxiety trait would attach higher self-relevance to the CMC attributes, and engage in a more socially-involved pattern of interpersonal responses in CMC. Implications of these findings are discussed.     

Cognitive effects of life stress and learned helplessness

Abstract Stressful life events and learned helplessness attributional styles have been shown to impact a variety of personal outcomes. This study examined how these factors influence two classes of cognitive behaviors: the occurrence of intrusive thoughts and performance in memory and verbal-spatial reasoning tasks. Negative life change and attributions for negative events predicted different types of cognitive responses. Individuals reporting higher levels of life stress were more likely to experience distracting thoughts that were unrelated to the current task, whereas individuals with learned helplessness attributional styles tended to have more worrisome thoughts about their task performance. In general, individuals reporting high levels of negative life stress tended to perform more poorly in tasks, whereas individuals with learned helplessness attributional styles tended to perform better than those who did not share this explanatory style. These results suggest that life stress and attributional style have important influecnes on cognitive processes, and that a learned helplessness attributional style can have beneficial effects on behavior in some situations.     

Mental toughness, stress, stress appraisal, coping and coping effectiveness in sport

The aim of the present study was to investigate the relationship between mental toughness, stressor appraisal, coping strategies and coping effectiveness among a sample of athletes. Participants were 482 athletes (male n = 305; female n = 177), aged between 16 and 45 years (M age = 20.44 years, SD = 3.98). In support of a priori predictions, mental toughness was associated with stress intensity and control appraisal, but not the type of stressor experienced by athletes. Total mental toughness and its six components predicted coping and coping effectiveness in relation to the self-selected stressor. In particular, higher levels of mental toughness were associated with more problem-focused coping, but less emotion-focused and avoidance coping. Coping effectiveness was influenced by the coping strategy employed by the athletes.     

Cognitive bias in acute stress disorder

Cognitive bias was investigated in survivors of motor vehicle accidents with either acute stress disorder (ASD; n=17) or no ASD (n=17). Participants completed the acute stress disorder interview, the Beck depression inventory, the Beck anxiety inventory, the impact of event scale, and a probability questionnaire (PQ) and a cost questionnaire (CQ) within four weeks of their accident. ASD participants exaggerated both the probability of negative events occurring, and the adverse cost of those events more than non-ASD participants. IES-Avoidance scores were the only significant predictors of both PQ and CQ scores. Findings are discussed in terms of the role of cognitive errors in posttraumatic adjustment.     

Cognitive abnormalities in post-traumatic stress disorder

Characteristically arising in response to overwhelmingly terrifying events, post-traumatic stress disorder (PTSD) is a disorder of memory: sufferers seemingly relive their trauma in the form of involuntary recollection. Prominent cognitive abnormalities, especially in memory functioning, have motivated research designed to elucidate the mediating mechanisms that produce PTSD symptoms, especially those involving involuntary recollection. Recent developments suggest a pathophysiological model of PTSD which includes hyporesponsive prefrontal cortical regions and/or a hyper-responsive amygdala. Other work has also identified above-average cognitive ability as a protective factor and below-average hippocampal volume as a vulnerability factor for PTSD among the trauma-exposed. These attempts to elucidate the mediating mechanisms of PTSD have been both cognitive and, more recently, cognitive-neuroscientific in emphasis.     

Cognitive strategies in coping with expedition stress

Expeditions provide a valuable opportunity for studying processes of coping with a stressful situation. An expedition to India organized by the British Schools Exploring Society has already been reported as being accompanied by positive changes on self-report personality scales. This paper is concerned with detailed cognitive coping measures completed throughout the 6 weeks of the expedition. It needs to be noted that the results relate to young adults and to those who provided detailed coping information; the generalizability of the result is a matter for future research. The expedition presented a mixture of physical and social stresses. Men enjoyed the physical experience more than women, but women enjoyed the social experience more than men. There was generally greater reliance on personal resources than on social support in coping with stress. This was particularly true for men in coping with physical stress and women in coping with social stress. In general, the physical stresses had been better anticipated than the social ones. Positive reformulations were much more widely used as coping strategies than avoidance/resignation strategies, especially so for physical stresses. However, use of avoidance/resignation strategies was the better predictor of outcome, with those who used them being least likely to show positive personality change as a result of the expedition. The results are related to current research on stress and coping.     

Cognitive control under stress: how stress affects strategies of task-set reconfiguration

This study investigated the effect of stress on cognitive control in task shifting. Subjects shifted between two tasks in an explicit cuing paradigm. Shift costs (i.e., performance decrements on task shifts relative to task repetitions) were measured for a long and a short cue-stimulus interval (CSI). Stress was varied by administering low-stress and high-stress IQ scales to two groups of subjects. In the low-stress group, shift costs were reduced with an increased CSI, a result that typically indicates anticipatory and shift-specific task-set reconfiguration. In the high-stress group, however, shift costs were independent of the CSI. This result is consistent with the idea that stress induces a change in the reconfiguration strategy, possibly to adapt to depleted resources.     

The dynamic nature of the stress appraisal process and the infusion of affect

Very little is known about the process in which people reappraise a stressful environment or the factors that may influence this process. In the current study, we address the several limitations to previous research regarding stress reappraisals and explore the role of affect on this process. A total of 320 participants (mean age = 20 years, 60% male) completed an increasingly demanding team-based coordination task. Mood and stress appraisals were assessed at three time points using self-report surveys during four different waves of data collection. The longitudinal design enabled us to assess primary and secondary reappraisals (change in appraisals during the experiment), task-irrelevant affect (affect assessed prior to experiment participation), and task-relevant affect (change in affect experienced during the experiment). Guided by the Transactional Theory of Stress, we argue that the relationship between primary reappraisal and secondary reappraisal is an accurate representation of a dynamic stress appraisal process. We found that participants were more likely to engage in the stress appraisal process when they experienced less task-irrelevant positive affect and greater task-relevant positive affect. Both task-irrelevant and task-relevant negative affect were not found to influence the stress appraisal process.     

Cognitive behavioral therapy of violence-related posttraumatic stress disorder

Posttraumatic stress disorder (PTSD) represents the most common psychiatric condition following exposure to violence. Although an increasing number of cognitive behavioral therapy (CBT) studies point to efficacy of this approach in ameliorating PTSD following violence, the methodological rigor of many studies has not been optimal. Further, a significant proportion of traumatized individuals does not benefit from CBT. This article reviews CBT outcome studies, discusses the methodological limitations of CBT studies for PTSD, and offers suggestions for future research. This review highlights the need for more systematic studies of components of CBT with a range of trauma populations to delineate the parameters of effective CBT for individuals with PTSD.     

Effect of cognitive appraisal on d' and response bias to experimental stress.

The effects of an intellectualization-denial passage designed to modify cognitive appraisal of stressor stimuli (gory scences) were evaluated in terms of sensory-decision theory analysis. The passage was found to reduce "felt stress" ') for certain pairs of the stimuli addressed by the passage content but to less effective in reducing stress (Lx) was reduced rather than increased wi;h presentation of the passage for the included simuli only. Differences in d' between subjects classified within treatment groups as repressors versus sensitizers were obtained for certain stimulus pairs generally in the direction of lower sensitivity for repressors. Results are discussed in terms of the effects of altered cognitive appraisal on the "prevention of stress" and on "defensive"denial.     

Cognitive appraisal of daily hassles in college students displaying high or low irrational beliefs

It is argued that Lazarus' construct of cognitive appraisal in life stress might usefully be related to Ellis' ABC model. To test the hypothesized role of cognitive appraisal in Lazarus' model of life stress, 240 male and female undergraduate students completed the Hassles Scale and the Irrational Beliefs Test (IBT). Based upon their scores on the IBT, subjects displaying high irrational beliefs differed significantly from subjects displaying low irrational beliefs in reported hassles frequency (higher for high irrational belief subjects) and reported hassles intensity (greater for high irrational belief subjects). Results are interpreted specifically as supportive of the cognitive appraisal construct in Lazarus' life stress model and generally as quite consistent with RET theory. An attempt is made to relate the cognitive appraisal construct to the ABC model in RET theory.Susan Mills Harran is a graduate of the M.S. Psychology program at Villanova University and is currently a Ph.D. candidate in clinical psychology at Hahneman University.Daniel J.

Extending the challenge-hindrance model of occupational stress: The role of appraisal

Interest regarding the challenge-hindrance occupational stress model has increased in recent years, however its theoretical foundation has not been tested. Drawing from the transactional theory of stress, this study tests the assumptions made in past research (1) that workload and responsibility are appraised as challenges and role ambiguity and role conflict are appraised as hindrances, and (2) that these appraisals mediate the relationship between these stressors and outcomes (i.e., strains, job dissatisfaction, and turnover intentions). For a sample of 479 employees, we found that although workload, role ambiguity, and role conflict could be appraised primarily as challenges or hindrances, they could also simultaneously be perceived as being both to varying degrees. Support was also found for a model in which primary appraisal partially mediated the stressor-outcome relationship.     

Cognitive therapy for post-traumatic stress disorder: development and evaluation

The paper describes the development of a cognitive therapy (CT) program for post-traumatic stress disorder (PTSD) that is based on a recent cognitive model (Behav. Res. Therapy 38 (2000) 319). In a consecutive case series, 20 PTSD patients treated with CT showed highly significant improvement in symptoms of PTSD, depression and anxiety. A subsequent randomized controlled trial compared CT (N = 14) and a 3-month waitlist condition (WL, N = 14). CT led to large reductions in PTSD symptoms, disability, depression and anxiety, whereas the waitlist group did not improve. In both studies, treatment gains were well maintained at 6-month follow-up. CT was highly acceptable, with an overall dropout rate of only 3%. The intent-to-treat effect sizes for the degree of change in PTSD symptoms from pre to post-treatment were 2.70-2.82 (self-report), and 2.07 (assessor-rated). The controlled effect sizes for CT versus WL post-treatment scores were 2.25 (self-report) and 2.18 (assessor-rated). As predicted by the cognitive model, good treatment outcome was related to greater changes in dysfunctional post-traumatic cognitions. Patient characteristics such as comorbidity, type of trauma, history of previous trauma, or time since the traumatic event did not predict treatment response, however, low educational attainment and low socioeconomic status were related to better outcome.
