The vicious cycle of psychopathology and stressful life events
10) stress. We also identified unique patterns of effects across specific types of psychopathology. For example, effects were larger for depression than anxiety. Furthermore, effects were sometimes larger in studies with younger participants, shorter time lags between assessments, checklist measures of stress, and for interpersonal stressors. Finally, a multilevel meta-analytic structural equation model suggested that dependent stress exacerbates…
Unique Functional Abnormalities in Youth with Combined Marijuana Use and Depression
Prior research has shown a relationship between early onset marijuana (MJ) use and depression; however, this relationship is complex and poorly understood. Here, we utilized passive music listening and fMRI to examine functional brain activation to a rewarding stimulus in 75 participants [healthy controls (HC), patients with major depressive disorder (MDD), frequent MJ users, and the combination of MDD and MJ (MDD + MJ)]. For each participant, a …
Disturbances of emotional awareness and expression in posttraumatic stress disorder
Demonstrations of deficient emotional awareness (EA) in posttraumatic stress disorder (PTSD) measured by alexithymia were extended to trait metamood, difficulties in emotion regulation, and trait mindfulness in 55 women with PTSD related to history of interpersonal/familial maltreatment. Perceived causes of interference of emotional expression were also identified that fully mediated the association between PTSD diagnostic status and alexithymic …

Neural Correlates of Levels of Emotional Awareness During Trauma Script-Imagery in Posttraumatic Stress Disorder
Objective: To examine individual differences in levels of emotional awareness as a predictor of the blood oxygenation level dependent (BOLD) response to trauma script-driven imagery in trauma-exposed individuals with (n = 25) and without (n = 16) posttraumatic stress disorder (PTSD). Methods: Participants completed the Levels of Emotional Awareness Scale (LEAS) and a functional magnetic resonance imaging trauma script-driven imagery paradigm. Res…
Decision-theoretic aspects of stress arousal and coping propensity
Scenario descriptor and laboratory studies evaluated a decision-theoretic model of stress arousal and coping propensity composed of 2 stress expectancies; namely, expected stress given engagement in coping activity and expected stress given nonengagement in coping activity. The model predicted (a) that coping propensity would vary inversely with the ratio of the first stress expectancy to the second and (b) that stress arousal would vary with the…
Locus of Control, Sensation Seeking, and Mathematical Models of Stress and Decisional Control
In a recent study, De Brabander and Hellemans (1996) reported that stress (somatic complaints) was inversely related to scores on personality scales of "thrill-and-adventure sensation seeking" and "internal locus of control." These observations, useful in their own right, are of further value when examined in the light of mathematical models of stress and decisional control. It is suggested that diminished stress associated with higher scores on …

A dynamic vulnerability perspective on stress and schizophrenia
Previous vulnerability models of schizophrenia, while strong, have serious limitations. To deal with the main areas of concern, a multifactor transactional conceptual framework of stress and schizophrenia, which builds on earlier models and incorporates recent research findings, is proposed. Research implications deriving from this framework are discussed

Use of the Simple Change Score in Correlational Analyses
This article examines the simple difference score (Y-X) as used in three different correlational analyses. As discussed in this paper, this difference score is viewed as a simple change from a pretest (X) to a posttest (1Y), but the generalizations apply to any difference score of the type (Y-X). The three classes of correlational analyses considered involve the correlation of initial score (X) with change (Y-X); the correlation of another variab…
Clear danger
The present trend in research on psychological stress is to examine the appraisal process for explanations of the wide individual ditferences typically found in responses to identical stressors. This approach comes at the expense of attempts to determine how aspects of the stimulus configuration tend to influence response independent of individual differences. The latter technique is unable to explain much of the variability in response, but it d…
The interactional model of anxiety
The interactional model of anxiety states that individuals who score high on trait anxiety measure for a specific situation dimension will respond with elevated state anxiety only in reaction to encounters with congruent situations. We tested this model by presenting subjects who scored high or low on ego threat, physical danger, novelty ambiguity, and daily routine trait measures with stressors representative of the four situation dimensions. Th…

Sources of differential stress response associated with psychometrically designated anxiety proneness
This research examined different aspects of the expression of psychometrically designated anxiety proneness related to dimensions of "ego threat" and "novelty ambiguity." In an ego-threatening situation, subjects were presented with abstract-reasoning items whose stress-relevant properties-item difficulty-had earlier been scaled among comparable samples. In the first study, comparisons focused on objective outcomes (records of task failure) as we…

Veridicality of cognitive mapping of stressor effects
In order to examine the veracity of judgment-questionnaire data regarding the effects of confronting a stressor in various contexts, judgments based on the imagined consequences of these encounters were scaled for both male and female subjects using individual-differences multidimensional scaling analyses. A parallel experiment was then carried out where a second group of subjects were directly exposed to the spectrum of stressor-context combinat…
Simultaneous Processing Of Multiple Stimulus Dimensions Among Paranoid And Nonparanoid Schizophrenics
In the first study, paranoid and nonparanoid schizophrenics and normals made dichotamous conceptual judgments about multidimensional visual stimuli. While the schizophrenics were not significantly inferior with respect to efficiency in multidimensional stimulus combination and did not display abnormal patterns of dimensional combination, they were less sensitive to interstimulus variation in the relevant attributes. In the second study, subjects …
Evidence of stress as a function of experimentally altered appraisal of stimulus aversiveness and coping adequacy
The present study examined the effects of initial appraisal of stimulus aversiveness and coping adequacy on subsequent evidence of stress. Results indicated that level of appraised coping efficacy had the most pronounced effect during stressor exposure and that the pattern of this effect was dependent on whether the source of the appraised coping resources was "personal" (the subject's own resources) or "environmental" (a bogus technique donated …
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. Diff…
Semantic Dimensionality of the Subjective Stress Scale
Ratings of the similarity of feelings denoted by the 14 adjectives of the Subjective Stress Scale were obtained from 24 male and 24 female undergraduates and analyzed with an individual-differences multidimensional scaling procedure. Results indicated high consistency in the similarity judgments among Ss and supported consideration of the items as varying along a single dimension

Scaling of the Subjective Stress Scale with a Sample of University Undergraduates
The Subjective Stress Scale was rescaled with a sample of university undergraduates using the method of successive intervals. Scale values were found to correlate .93 with previously established values obtained from a military sample although the order of the items along the stress continuum changed somewhat. The revised order for student populations is presented
