The dimensionality and correlates of the Intolerance of Uncertainty Scale (IUS) were examined in a sample of 239 university students. In addition to completing the IUS, participants completed measures of worrying, anxious arousal, anhedonic depression, the big five personality dimensions, and the Need for Closure Scale. A factor analysis of the IUS(More)
Two studies examined the relation between psychological trauma and schizotypal symptoms. In Study 1, in which 1,510 adults completed telephone interviews, both childhood maltreatment and the experience of an injury or life-threatening event were significantly associated with schizotypal symptoms. In Study 2, in which 303 adults (oversampled for having(More)
The present research examined the hypothesis that cognitive processes are modulated differentially by trait and state negative affect (NA). Brain activation associated with trait and state NA was measured by fMRI during an attentional control task, the emotion-word Stroop. Performance on the task was disrupted only by state NA. Trait NA was associated with(More)
BACKGROUND There is a growing recognition that emotional traits are important for understanding many mental health disorders, including major depressive disorder (MDD). The present research examined (a) the relation between MDD and the emotional trait of affective instability, and (b) whether individual facets of affective instability, affect intensity and(More)
The present study examined the utility of the anhedonic depression scale from the Mood and Anxiety Symptoms Questionnaire (MASQ-AD scale) as a way to screen for depressive disorders. Using receiver-operating characteristic analysis, we examined the sensitivity and specificity of the full 22-item MASQ-AD scale, as well as the 8- and 14-item subscales, in(More)
The present study examined the relations between dimensions of intolerance of uncertainty (i.e., desire for predictability and uncertainty paralysis) and perceptions of threat (i.e., perceptions of the probabilities and costs of future undesirable outcomes) in a sample of 239 college students. Uncertainty paralysis was positively associated with both(More)
Attentional control theory (Eysenck et al., 2007) posits that taxing attentional resources impairs performance efficiency in anxious individuals. This theory, however, does not explicitly address if or how the relation between anxiety and attentional control depends upon the perceptual demands of the task at hand. Consequently, the present study examined(More)
Background Habituation of the fear response, critical for the treatment of anxiety, is inconsistently observed during exposure to threatening stimuli. One potential explanation for this inconsistency is differential attentional engagement with negatively valenced stimuli as a function of anxiety type. Methods The present study tested this hypothesis by(More)
Multi-tasking can increase susceptibility to distraction, affecting whether irrelevant objects capture attention. Similarly, people with depression often struggle to concentrate when performing cognitively demanding tasks. This parallel suggests that depression is like multi-tasking. To test this idea, we examined relations between self-reported levels of(More)
This study examined how elevated levels of worry and anhedonic depression are associated with affect intensity, attention to emotion, and clarity of emotion. University students (N = 923) completed the Affect Intensity Measure, the Trait Meta Mood Scale, the Penn State Worry Questionnaire and the anhedonic depression subscale from the Mood and Anxiety(More)
