Abstract
OBJECTIVE To evaluate the severity of depression, anxiety, associated risk factors, and cognitive distortion in Korean patients with ulcerative colitis (UC) and Crohn's disease (CD). METHODS This study included 369 patients with inflammatory bowel disease. The severity of depression and anxiety was examined using Patient Health Questionnaire-9 and Hospital Anxiety and Depression Scale. The Anxious Thoughts and Tendencies scale was used to measure catastrophizing tendency. Multivariate regression analyses were performed. RESULTS The predictors of depression were marital status, anti-tumor necrosis factor-α (TNF-α) agent use, age, and body mass index in UC patients and marital status, disease activity, alcohol use, and employment status in CD patients. For anxiety, sex and marital status were the associated factors in UC patients, whereas steroid use was the only significant predictor in CD patients. Comparing the cognitive distortion level, there were no significant differences between UC and CD patients although there was an increasing tendency according to the severity of depression or anxiety. CONCLUSION If patients are accompanied by high levels of depression or anxiety and their associated risk factors including TNF-α agent or steroid use, it is recommended that not only symptoms are treated but also cognitive approach and evaluation be performed.

Abstract
Reliability and validity of the Symptom Checklist 90 Revised (SCL-90-R) was investigated to determine if this instrument is appropriate for use with Hispanic college students. The sample(28males, 177females) consistedof 101participantswho identified as Anglo and 104 who identified as Hispanic (6 did not identify their ethnicity). Participants ranged in age from 17 to 50. Cronbach’s alpha was used to assess each of the SCL-90-R’s subscales. Multivariate analysis of variance (MANOVA) was employed to check for significant differences between Anglo and Hispanic students’pretest scores. The extent to which the SCL-90-R measures change in both samples in a similar way was investigated. The data support the reliability and validity of the SCL-90-R as a measure of psychological symptoms for Hispanic college students.

Abstract
BACKGROUND The question of whether certain anxiety disorders are especially related to a cognitive style characterized by an exaggerated perception of threat and appraisal of the future as excessively unpredictable (general anxiety-prone cognitive style) remains open. OBJECTIVES This study aimed to compare patients with generalized social anxiety disorder (SAD), generalized anxiety disorder (GAD), panic disorder with agoraphobia (PDA), and panic disorder without agoraphobia (PD) in terms of the levels of general anxiety-prone cognitive style when the severity of general distress and psychopathology is controlled for and to ascertain whether a co-occurring depressive disorder contributes substantially to the levels of this cognitive style. METHODS The Anxious Thoughts and Tendencies Scale, a measure of a general anxiety-prone cognitive style, and Symptom Checklist 90-Revised were administered to 204 patients with various anxiety disorders who attended an outpatient anxiety disorders clinic and were diagnosed based on a semistructured diagnostic interview. RESULTS Patients with principal diagnoses of SAD and GAD had a more prominent general anxiety-prone cognitive style than patients with principal diagnoses of PD and PDA when the severity of general distress and psychopathology was controlled for. The presence or absence of a co-occurring depressive disorder had no bearing on this finding. CONCLUSIONS The general cognitive component characterizes SAD and GAD more than it does PD and PDA, and a co-occurring depressive disorder does not affect this finding. These results have implications for distinguishing between various anxiety disorders.

Abstract
This study investigated an anxiety-prone cognitive style (measured by the Anxious Thoughts and Tendencies Questionnaire, AT&T) as a predictor of the acute response to increasing alprazolam plasma levels in panic disorder. Panic disorder patients (n=26) were treated with escalating doses of alprazolam for 4 weeks, then a fixed dose of 1 mg four times a day for 4 weeks. At 0, 1, 2, 3, 4, 6, and 8 weeks, trough alprazolam plasma levels; clinical, self-report, and performance measures; and vital signs were assessed. Panic attack data were from daily diaries. The repeated response measures were analyzed in relation to alprazolam plasma levels using SAS GENMOD, with patients classified as high or low on the baseline AT&T. Panic attacks, anticipatory anxiety, fear, avoidance, overall agoraphobia, the Hamilton Anxiety Rating Scale, and clinicians' global ratings improved with increasing alprazolam plasma levels. Hopkins Symptom Checklist-90 Anger-Hostility; Profile of Mood States Vigor, Confusion, and Friendliness; and speed and accuracy of performance worsened. Patients with high AT&T scores were worse throughout the study on situational panics, fear, avoidance, overall agoraphobia, the Hamilton Anxiety Rating Scale, the Hamilton Rating Scale for Depression, and Clinical Global Improvement; most Hopkins Symptom Checklist-90 clusters; Profile of Mood States Anxiety, Depression, and Confusion; and Continuous Performance Task omissions. We conclude that in panic disorder: (1) alprazolam has a broad spectrum of clinical activity related to plasma levels in individual patients; (2) sedation, disinhibition, and performance deficits may persist for at least a month after dose escalation ends; (3) marked anxiety-prone cognitions predict more symptoms throughout treatment, but do not modify the response to alprazolam and therefore should not influence the choice of alprazolam as treatment.

Abstract
The objective of this study was to ascertain the relationship of alprazolam plasma levels and an anxiety-prone cognitive style to the characteristics and severity of early withdrawal after abrupt discontinuation of alprazolam in 26 patients with panic disorder. After 8 and 9 weeks of fixed-dose treatment, patients were hospitalized for 24 hours. On 1 admission, ordered at random, treatment was maintained; on the other, placebo was substituted double blind. The Anxious Thoughts and Tendencies questionnaire was administered before treatment. Alprazolam plasma levels were measured 7 times on the day after each admission. Before each blood sampling, the Profile of Mood States and performance tasks were administered, and vital signs were recorded. On the day after abrupt discontinuation of alprazolam, Profile of Mood States anxiety, depression, fatigue, and confusion increased; vigor and elation decreased; speed on the digit symbol substitution task improved; and systolic blood pressure increased substantially over time. High Anxious Thoughts and Tendencies scores were related specifically to more anxiety. Our findings (1) confirm that dysphoric mood, fatigue, low energy, confusion, and elevated systolic blood pressure are part of the early syndrome of withdrawal from alprazolam in patients with panic disorder, notably as the drop in plasma levels approaches 50%; (2) indicate a psychomotor deficit persisting beyond dose stabilization; (3) suggest that an anxiety-prone cognitive style measurable before undertaking treatment may be a risk factor for more severe anxiety upon discontinuation; and (4) provide a rationale for applying cognitive behavior therapy during benzodiazepine taper.

Abstract
Cognitive models of anxiety disorders propose that certain cognitive constructs, that is, underlying beliefs and cognitive processes, may be specific for particular disorders. In this article, we review the specificity of four representative cognitive constructs-anxiety sensitivity, pathological worry, intolerance of uncertainty, and thought-action fusion-for particular disorders. Conceptual overlap, inconsistent definitions, and insufficient consideration of the components of these constructs are limitations of the existing literature. We suggest that the constructs are unlikely to be pathognomonic for any given disorder or to occur in isolation. Rather, the association of each cognitive construct is evident, to varying degrees, with different disorders. Relative to other disorders, anxiety sensitivity is to a certain extent specific for panic disorder, as are pathological worry for generalized anxiety disorder, intolerance of uncertainty for generalized anxiety disorder and obsessive-compulsive disorder, and thought-action fusion for obsessive-compulsive disorder. We discuss the implications of these findings for diagnostic systems and treatment, and suggest areas for further research.

Abstract
PURPOSE This study examined the relationships among certain subtypes of panic attacks (full vs. limited symptom; spontaneous vs. situational) and between these subtypes, panic disorder subtypes, and other characteristics of panic disorder, especially agoraphobia. METHOD Data were drawn from a large (n = 1,168) treatment study of panic disorder in which panic attacks were carefully subtyped and counted using a diary. Relationships between variables at baseline were examined primarily using non-parametric methods, and the course of improvement for panic subtypes among completers was plotted. RESULTS The median number of spontaneous panic attacks per week at baseline was similar among patients with panic disorder without agoraphobia (PD), limited phobic avoidance (PDL), and agoraphobia (PDA). The median number of situational attacks and the median agoraphobia ratings rose progressively across diagnostic subtypes. Anticipatory anxiety, HAM-A, HAM-D, and disability scores were higher in PDA than in PD. Full and limited symptom panic attacks were positively correlated. The proportion of total attacks that were limited rose during the first two weeks of treatment, suggesting conversion of full to limited symptom attacks before complete disappearance. Spontaneous and situational attacks were correlated minimally or not at all. Agoraphobia ratings were more positively correlated with situational than with spontaneous panic attacks. Few of the correlations among measures at baseline were high. CONCLUSIONS Full and limited symptom panic attacks differ primarily in severity. Spontaneous and situational attacks are relatively independent, and situational attacks are more closely related to agoraphobia. These findings are consistent with previous work suggesting that spontaneous attacks reflect a biological component, whereas situational attacks reflect a cognitive component in the psychopathology-- and possibly the pathogenesis-- of panic disorder. This provides a rationale for the use of combined pharmacotherapy and psychotherapy in the treatment of panic disorder. Future investigations of panic disorder should carefully separate panic attack subtypes.

Abstract
To investigate the cognitive characteristics that affect the emotional and functional distress caused by tinnitus and to decide and test the model to explain their relations, 167 patients with tinnitus, who visited Samsung Medical Center, Seoul, Korea between March 2001 and May 2002 were recruited. To examine their features related to tinnitus, the following scales were administered; Tinnitus-related basic questionnaire including dysfunctional beliefs, Tinnitus Handicap Inventory, State-Trait Anxiety Inventory, Anxious Thought and Tendencies, Self-Consciousness Scale, and modified 'catastrophic thought' from Coping Strategies Questionnaire. The results showed that the duration of experiencing tinnitus was 4.7 +/-7.1 yr, those who complained of hearing one sound were the most common (45.5%), and hearing sounds similarly described to whistling were the most common (22.5%). Also, there were significant correlations among tinnitus features, cognitive characteristics, and distresses from tinnitus. As a result of testing the model, Normed fit index, Incremental fit index, Tucker-Lewis index, and Comparative fit index were over .90, indicating that it is a good model, and Root mean square error of approximation showed a reasonable fit. Also, the direct effects of the trait or severity of tinnitus on distress did not appear to be significant, thus it appeared to be affecting indirectly through the cognitive characteristics. This result shows that cognitive interventions can be important for the psychological adaptations of tinnitus patients.

Abstract
BACKGROUND The factor structure and psychometric properties of the revised Anxious Thoughts and Tendencies Scale (AT&T) is investigated. METHODS An Australian sample of 215 students and 33 patients diagnosed with an anxiety disorder completed a battery of anxiety-related questionnaires. RESULTS Factor analysis indicated one factor, which accounted for 38% of the variance and had high internal consistency and reliability. Significant relationships were found with measures of anxiety, anxiety sensitivity, catastrophic cognitions, fear and depression. The AT&T discriminated between students and patients, and between students with high or low levels of anxiety and fear. LIMITATIONS The size of the clinical sample was very small and the study needs to be replicated with a large and carefully recruited clinical sample. CONCLUSIONS These results support the AT&T as a valuable and psychometrically sound measure of the cognitive aspects of anxiety.

Abstract
OBJECTIVE This study compared scores on the Anxious Thoughts & Tendencies (AT&T) questionnaire, a putative measure of a general anxiety-prone cognitive style, among patients with panic disorder without agoraphobia (PD, n=62), panic disorder with agoraphobia (PDA, n=29), generalized anxiety disorder (GAD, n=43), limited social phobia (LSP, n=34), generalized social phobia (GSP, n=33), and community residents (n=319). METHOD Candidates for treatment studies completed a diagnostic interview and the AT&T. AT&T scores were compared among anxious groups using analysis of variance. Then depressed and non-depressed patients were compared. The final analysis compared anxious groups without comorbid depressive or anxiety disorders. RESULTS AT&T scores were highest in PDA patients, followed by patients with GAD or GSP, then patients with PD or LSP, with community residents lowest. Depressed patients were higher than non-depressed patients. Patients with current or past comorbid depressive disorders did not differ. The ranking of anxious groups on AT&T scores remained unchanged after exclusion of patients with comorbid disorders. Patients with PD or LSP without comorbidity had the same AT&T levels as the community sample. CONCLUSIONS The AT&T discriminates PDA and GAD from PD per our hypothesis. The low AT&T levels among patients with PD and LSP suggest no association with a general anxiety-prone cognitive style. LSP and GSP may be distinct disorders. The cognitive style assessed by the AT&T is also associated with depression and may be a marker for vulnerability to depression. Definitive conclusions about a pathogenic role for cognitions require their measurement before the onset of the disorder.

Abstract
It was proposed that pre-post regression slopes be used to index treatment response when the effect of baseline scores differed among treatments (interaction between treatment and baseline score). Reanalyses of two studies using imipramine and fluoxetine in panic disorder showed doserelated decreases in pre-post slopes for the frequency of unexpected panic attacks, but not for the frequency of situational panic attacks or measures of agoraphobia. This report presents similar analyses of data from a study using moclobemide. Patients (N = 452) with panic disorder were randomized to placebo or a fixed dose of moclobemide (75, 150, 300, 600, or 900 mg/day). They were treated double-blindly and evaluated at baseline and 1, 2, 3, 4, 6, and 8 weeks later. The authors analyzed the frequency of unexpected and situational panic attacks compiled from a daily diary, and fear and avoidance ratings based on the patient's main phobia using baseline (pre) and end-point (post) values for all randomized patients. Adjoining dose groups were combined. Both unexpected and situational panic attacks showed systematic doserelated suppression of pre-post treatment slopes. Neither pre-post slopes nor adjusted posttreatment means for fear and avoidance differed reliably between treatment arms. This study replicates the authors' earlier findings, except for situational panic attacks, which probably were not reliably identified. Antidepressants selectively suppress panic attacks, especially unexpected attacks, but not agoraphobia. The findings are consistent with the hypothesis that panic disorder with agoraphobia has clinically separable biologic and cognitive components that respond differentially to treatment. Antidepressants benefit primarily patients with many unexpected panic attacks. Investigators should evaluate pre-post treatment slopes before comparing adjusted posttreatment means (analysis of covariance).

Abstract
The purpose of this study was to test the following interrelated hypotheses in a larger sample by attempting to replicate supportive results from a small therapeutic study: (1) the pathogenesis of panic disorder includes at least two identifiable components: a biological component represented by spontaneous (unexpected) panic attacks, and a cognitive component represented by situational attacks and especially by phobias; (2) these components respond differently to treatment; (3) many biological processes respond to an effective intervention in proportion to their deviance from "normal" prior to treatment ("Law of Initial Value"); and (4) the response of spontaneous panic attacks to an effective treatment conforms to that model. Previously, the authors reanalyzed an 8-week therapeutic study of panic disorder that included groups treated with placebo and with imipramine (225 mg daily). The criteria of response were spontaneous panic attacks (biological component), situational panic attacks (both components), and agoraphobia ratings (cognitive component). The analyses compared the regression lines for posttreatment status on pretreatment status in the imipramine and placebo groups. The effect of imipramine on spontaneous panic attacks fitted the hypothesized model: the pre-post slope in the placebo group was approximately 1 (45 degrees), whereas the slope in the imipramine group was approximately 0. There was no significant difference in pre-post slopes between the imipramine and placebo groups for situational panic attacks or agoraphobia ratings. For this report, the authors applied the same approach to another larger data set from a study using a similar design, but a different antidepressant. In this multicenter, double-blind study, patients with panic disorder were randomly assigned to receive 10 weeks of treatment with placebo (N = 78) or fluoxetine 10 mg (N = 84) or 20 mg (N = 81) daily. Spontaneous and situational panic attacks were registered in a daily diary, and agoraphobia was rated at each visit. Using baseline and endpoint data, fluoxetine had a statistically significant, dose-dependent, suppressive effect on spontaneous panic attacks, as measured by the pre-post slopes in the three treatment groups. The placebo group showed some response (slope = 0.69). There were no significant drug effects on situational panic attacks. On ratings of agoraphobia, the slopes in the placebo and the fluoxetine 20 mg groups did not differ, but the slope in the fluoxetine 10 mg group was significantly less than that in the placebo group, suggesting a therapeutic drug effect on agoraphobia only at the lower dose. These results are consistent with the stated hypotheses. They suggest that the therapeutic effects of antidepressants on panic disorder may be due primarily to the specific suppression of spontaneous panic attacks among patients with high baseline pathologic findings. Implications of these results for concepts of pathogenesis, clinical practice, and therapeutic research regarding panic disorder are discussed.
