Worry and Rumination: Repetitive Thought as a Concomitant and Predictor of Negative Mood

Abstract: Worry and depressive rumination have both been described as unproductive, repetitive thought which contributes to anxiety or depression, respectively. It was hypothesized that repetitive thought, rather than its specific forms, is a general concomitant of negative mood. Study 1 was a cross-sectional test of the hypothesis. Repetitive thought was positively correlated with anxiety and depression in students (n = 110). In patients (n = 40), repetitive thought was positively correlated with anxiety and depression, and rumination was also specifically correlated with depression. Study 2 was a prospective test of the hypothesis. In students (n = 90), there were significant cross-sectional relationships between repetitive thought and both anxiety and depression. In addition, repetitive thought at least partially predicted maintenance of anxious symptoms. Phenomena such as goal interruption, failures of emotional processing, and information processing may lead to repetitive thought which increases negative mood states, including both anxiety and depression.

Children's Memories for Painful Cancer Treatment Procedures: Implications for Distress

Abstract: Children (ages 3 to 18, N = 55) diagnosed with leukemia were tested for their memories of lumbar punctures (LPs), a repeated and painful part of the cancer treatment protocol. Memory for both event details and the child's emotional responses was assessed one week after the LP. Children of all ages displayed considerable accuracy for event details, and accuracy increased with age. Overall recall accuracy for event details and emotional responses was similar. Recall among children given oral Versed was similar to that among children not given Versed. Finally, higher distress predicted greater exaggerations in negative memory 1 week later (although controlling for age weakened this relationship); moreover, greater exaggerations in negative memory predicted higher distress at a subsequent LP. These results indicate that children's memories play an important role in their experience of distress during repeated stressful events.

Pain-Sensitive Temperament: Does It Predict Procedural Distress and Response to Psychological Treatment Among Children With Cancer?

Abstract: Objective: To evaluate the relationship between pain sensitivity and children’s distress during lumbar punctures (LPs), and whether pain sensitivity functions as a moderator of children’s responses to a psychological intervention aimed at reducing LP distress. Method: Fifty-five children with acute lymphoblastic leukemia (ages 3 to 18) and their parents completed a questionnaire measure of pain sensitivity. Self-report, physiological, and observed measures of distress were collected during the study baseline LP. Children were then randomized into a psychological intervention or an attention control group. Postintervention and follow-up LPs were observed. Results: Higher levels of pain sensitivity were associated with greater anxiety and pain, both prior to and during the LP. Preliminary analyses indicated that pain sensitivity moderated the effects of intervention on distress. Children who were more pain-sensitive and who received no intervention showed greater increases in LP distress over time. In contrast, children who were more pain-sensitive and who received intervention showed greater decreases in LP distress over time. Conclusions: A measurement of pain sensitivity may be useful in pediatric oncology settings for effectively targeting pain-vulnerable children for psychological intervention. Preliminary analyses indicate that an empirically-supported intervention for procedural distress is efficacious for those children who are most pain-sensitive.

Autonomic reactivity of panic patients during a CO2 inhalation procedure

Abstract: The objectives of this study were to compare continuous subjective and physiological responses of panic disorder patients and normal controls during 5% CO2 inhalation. Psychophysiological responses of panic disorder patients (n = 42) and controls (n = 25) were monitored during baseline (20 min), 5% CO2 inhalation (20 min), and recovery (20 min). The data were compared at baseline and over periods of the experiment using analysis of variance. A subgroup of patients who experienced panic attacks during the CO2 inhalation (n = 12) were significantly different from the other subjects on baseline heart rate and on variability of systolic and diastolic blood pressure, skin conductance, and breathing variability (length and number of breathing pauses and length of breathing cycle variability). Inspection of the data showed that elevation in blood pressure and breathholding were present during some of the panic attacks, suggesting that some attacks may represent a complex psychophysiological response with elements of a “freezing” reaction, well described in animal experiments, which can quickly shift to a “fight/flight” reaction that is usually characterized by an increase in heart and breathing rate. However, some patients had only minimal changes in breathing and others had minimal psychophysiological changes during the time they indicated that they had a panic attack. Panic attacks are not homogeneous and may be characterized by a variety of physiological and cognitive responses. This may indicate that biological mechanisms of panic include abnormality in many functionally connected areas of the brain responsible for complex psychophysiological reactions to multiple threatening situations.

Verbalization and imagery during worry activity.

Abstract: This study examined a model of worry as verbal activity that suppresses imagery and autonomic fear. The effects of emotional imagery vs. verbalization upon worry and fearfulness of an impending public speaking situation were assessed in 54 public speaking anxious participants who were categorized as worriers. Randomly assigned groups that processed the impending public speaking task either verbally or imaginally were compared to a group that received no processing instructions. Subjective distress was measured throughout the study. Results revealed partial support for the hypotheses that proportions of verbal thought and imagery shift upon threat presentation and a mitigation of fear habituation with verbalization. However, interpretation of between-group differences was complicated because the groups did not report consistent or complete adherence to cognitive processing instructions. Methodological and design implications for future investigations in this area are discussed. Depression and Anxiety 11:169–174, 2000. © 2000 Wiley-Liss, Inc.

The Anxiety Attitude and Belief Scale: initial psychometric properties in an undergraduate sample

Abstract: The development of a measure of attitudes and beliefs intended to index a psychological vulnerability to anxiety problems is described. Items for the Anxiety Attitude and Belief Scale (AABS) were developed by polling researchers and clinicians active in the area of anxiety disorders. The initial psychometric properties of the resulting scale were examined in a sample of undergraduates. The three factors underlying the AABS appear to index theoretically interesting domains, and both the total and factor scores showed adequate reliability. Confirmatory factor analyses suggested that the AABS indexes a distinct, although likely overlapping, domain from the Dysfunctional Attitude Scale (A. N. Weissman and A. T. Beck, presentation at the meeting of the Association for the Advancement of Behavior Therapy, Chicago, IL, 1978), a theoretically related scale of cognitive vulnerability to depression and other emotional disorders. Finally, a cross- lagged panel analysis indicated no causal relationship between the AABS and depression. On the other hand, this analysis suggested a causal relationship between the AABS and anxiety, with prior AABS scores predicting later anxiety, rather than the reverse.
