The Anxiety Sensitivity Index for Children: factor structure and relation to panic symptoms in an adolescent sample.

This study examines the factor structure underlying the Anxiety Sensitivity Index for Children (ASIC. J Anxiety Disord, 12 (1998) 307) in an adolescent sample. Three-hundred-and-eight adolescents, aged 12 to 18, completed the ASIC and measures of anxiety and depression. Factor analysis of the ASIC items resulted in a two-factor structure that is similar to that reported by Laurent et al. These two factors included a physical concerns dimension and a mental concerns dimension similar to those found in studies of adult anxiety sensitivity. Subscales measuring these two factors demonstrated concurrent validity, showing particularly close associations with measures of panic symptoms. In addition, both of these subscales showed incremental validity in predicting panic symptoms after controlling for the other anxiety sensitivity subscale and a measure of depression. These results provide evidence that the anxiety sensitivity construct is applicable during adolescence and support the use of the ASIC.

The facilitative effects of heart-rate feedback in the emotional processing of claustrophobic fear.

This study examines predictions derived from Foa and Kozak's theory of emotional processing. We hypothesized that the provision of heart-rate feedback would facilitate emotional processing through a fuller activation of the participant's fear structure, and by focusing participants' attention on information that is incompatible with the fear structure, i.e., the interoceptive pattern of habituation. Nonclinical students (N = 54) showing marked claustrophobic fear received 30 min of self-directed exposure to a claustrophobic chamber. Three exposure conditions (heart-rate feedback, paced-tone control, and exposure only control) were examined across six 5-min exposure trials. Participants receiving heart-rate feedback displayed greater between-trial habituation across treatment trials and lower levels of fear at post-treatment. Treatment process findings failed to support the fear activation hypothesis. Implications of the findings for theories of fear reduction are discussed.

Substance use and non-clinical panic attacks in a young adult sample.

This study examines panic attacks and substance use in a non-clinical, young adult sample. Two hundred seventy-nine college students completed questionnaires that assessed non-clinical panic attacks, alcohol and drug use behavior, and anxiety and depression symptoms. Non-clinical panickers (n = 25) were significantly more likely than non-panickers (N = 222) to report using sedatives, but not alcohol, cocaine, stimulants, or other drugs. Among non-clinical panickers, sedative use was not associated with distress about panic attacks, panic attack frequency, the occurrence of unexpected attacks, or general anxiety or depression symptoms. Coping-motivated alcohol use, though not associated with non-clinical panic, was significantly associated with anxiety and depression symptoms. These results are discussed in terms of theories of the co-morbidity between substance use and panic disorder.

Coping with negative symptoms of schizophrenia: patient and family perspectives.

An exploratory study was conducted of the strategies that schizophrenia patients and their relatives employ to cope with negative symptoms. Coping strategies and their perceived efficacy were elicited in semistructured interviews conducted separately with patients and relatives. Coping responses were coded according to the following dimensions: behavioral-cognitive, social-nonsocial, and problem focused-emotion focused. Overall, the number of coping strategies was related to perceived coping efficacy for both patients and relatives, regardless of the type of strategy. Perceived coping efficacy tended to be highest for apathy; intermediate for alogia, anhedonia, and inattention; and lowest for blunting. Relatives with more knowledge about schizophrenia used more coping strategies and reported higher levels of coping efficacy. Patient rejection by relatives and distress (either patient or relative) tended to not be related to coping strategies. The findings suggest that patients and relatives use a wide variety of strategies to cope with negative symptoms of schizophrenia. Future clinical work and research need to evaluate whether families may benefit from psychoeducational approaches to teaching them how to better manage negative symptoms.

Coping strategies and posttraumatic stress disorder in female victims of sexual and nonsexual assault.

The coping behaviors and posttraumatic stress disorder (PTSD) symptoms of 215 female assault victims (103 rape victims and 112 nonsexual assault victims) were assessed within 2 weeks following the assault (Time 1), and 133 of them (62%) were followed up 3 months later (Time 2). Posttrauma symptom severity significantly decreased during the 3-month study period, but PTSD severity levels at Times 1 and 2 were highly correlated. Three coping scales were constructed on the basis of exploratory factor analyses: Mobilizing Support, Positive Distancing, and Wishful Thinking. Three months postassault, rape victims showed higher levels of wishful thinking and PTSD than nonsexual assault victims. Wishful thinking showed a positive association and positive distancing a negative association with PTSD severity, controlling for assault type, initial levels of PTSD severity, and other coping strategies. The clinical relevance of these findings is discussed.

The effects of alcohol consumption on laboratory-induced panic and state anxiety.

BACKGROUND: This study tested whether alcohol consumption reduces anxiety and panic associated with a panic-challenge procedure. METHODS: Subjects with panic disorder were randomly assigned to consume either a moderate dose of alcohol or a nonalcoholic placebo. All subjects were told that they were drinking alcohol to control beverage expectancies. Following the beverage administration, subjects underwent a panic challenge (35% carbon dioxide) and a series of anxiety symptom assessments. RESULTS: Subjects who consumed alcohol reported significantly less state anxiety both before and after the challenge. In response to the challenge, subjects who consumed alcohol experienced significantly fewer panic attacks when applying liberal panic criteria; however, this effect only approached significance when applying conservative panic criteria. CONCLUSIONS: These findings suggest that alcohol acts acutely to reduce both panic and the anxiety surrounding panic, and they lend support to the view that drinking behavior among those with panic disorder is reinforced by this effect. We suggest that this process may contribute to the high rate at which alcohol-use disorders co-occur with panic disorder.

Claustrophobic fear behavior: a test of the expectancy model of fear.

The present study examined Reiss and McNally's expectancy model in the prediction of claustrophobic fear, measured across three domains. Non-clinical subjects (N = 117) reporting claustrophobic concerns were administered a behavioral approach test to a claustrophobic chamber. Consistent with the expectancy model, danger expectancy, anxiety expectancy and the interaction of anxiety sensitivity and anxiety expectancy accounted for unique portions of behavioral performance, with other variables partialled out. The expectancy model variable set, however, did not meaningfully relate to subjective fear or heart-rate reactivity. The formulation of anxiety sensitivity as a measure of the salience of anxiety is discussed. These findings lend support to the theory as a model for the behavioral dimension of pathological fear, but not the subjective or physiological facets.
