Comparison of palmtop-computer-assisted brief cognitive-behavioral treatment to cognitive-behavioral treatment for panic disorder.

In the present study, the authors sought to determine whether the efficiency and cost-effectiveness of cognitive-behavioral treatment (CBT) for panic disorder could be improved by adjunctive computer-assisted therapy. Eighteen participants who met Diagnostic and Statistical Manual of Mental Disorders (3rd ed., revised; American Psychiatric Association, 1987) criteria for panic disorder were randomly assigned to a 12-session CBT (CBT12) condition (D. H. Barlow & M. G. Craske, 1989) or to a 4-session computer-assisted CBT (CBT4-CA) condition. Palmtop computers, with a program developed to incorporate basic principles of CBT, were used by CBT4-CA clients whenever they felt anxious or wanted to practice the therapy techniques and were used by all participants as a momentary assessment tool. CBT4-CA clients carried the computer at all times and continued to use it for 8 weeks after termination of therapy. Analyses of clinically significant change showed superiority of CBT12 at posttest on some measures; however, there were no differences at follow-up.

Preliminary evidence for cognitive mediation during cognitive-behavioral therapy of panic disorder.

Cognitive-behavioral therapy (CBT) and pharmacotherapy are similarly effective for treating panic disorder with mild or no agoraphobia, but little is known about the mechanism through which these treatments work. The present study examined some of the criteria for cognitive mediation of treatment change in CBT alone, imipramine alone, CBT plus imipramine, and CBT plus placebo. Ninety-one individuals who received 1 of these interventions were assessed before and after acute treatment, and after a 6-month maintenance period. Multilevel moderated mediation analyses provided preliminary support for the notion that changes in panic-related cognitions mediate changes in panic severity only in treatments that include CBT.

Discontinuation of benzodiazepine treatment: efficacy of cognitive-behavioral therapy for patients with panic disorder

OBJECTIVE: The primary disadvantage of high-potency benzodiazepine treatment for panic disorder is the difficulty of discontinuing the treatment. During treatment discontinuation, new symptoms may emerge and anxiety may return, preventing many patients from successfully discontinuing their treatment. In this controlled, randomized trial the authors investigated the efficacy of a cognitive-behavioral program for patients with panic disorder who were attempting to discontinue treatment with high-potency benzodiazepines. METHOD: Outpatients treated for panic disorder with alprazolam or clonazepam for a minimum of 6 months and expressing a desire to stop taking the medication (N = 33) were randomly assigned to one of two taper conditions: a slow taper condition alone or a slow taper condition in conjunction with 10 weeks of group cognitive-behavioral therapy. RESULTS: The rate of successful discontinuation of benzodiazepine treatment was significantly higher for the patients receiving the cognitive-behavioral program (13 of 17; 76%) than for the patients receiving the slow taper program alone (four of 16; 25%). There was no difference in the likelihood of discontinuation success between the patients treated with alprazolam and those who received clonazepam. At the 3-month follow-up evaluation, 77% of the patients in the cognitive-behavioral program who successfully discontinued benzodiazepine treatment remained benzodiazepine free. CONCLUSIONS: These findings support the efficacy of cognitive-behavioral interventions in aiding benzodiazepine discontinuation for patients with panic disorder.     

Impact of cognitive-behavioral treatment on quality of life in panic disorder patients.

Panic disorder (PD) is associated with significant social and health consequences. The present study examined the impact of treatment on PD patients' quality of life. Patients (N?=?156) meeting DSM-III—R (Diagnostic and Statistical Manual of Mental Disorders [3rd ed., rev.]; American Psychiatric Association, 1987) criteria for PD with agoraphobia were randomly assigned to group cognitive behavioral treatment (CBT) or a delayed-treatment control. An assessment battery measuring the major clinical features of PD as well as quality of life was administered at baseline (Week 0), post treatment (Week 9) and 6-month follow-up (Week 35). Consistent with previous studies, PD patients displayed significant impairment in quality of life at intake. Compared with delayed-treatment control participants, CBT-treated participants showed significant reductions in impairment that were maintained at follow-up. Consistent with prediction, anxiety and phobic avoidance were significantly associated with quality of life, whereas frequency of panic attacks was not.

Comorbid panic disorder and major depression: implications for cognitive-behavioral therapy

The Fourier transform infrared spectrum of H3SiI has been recorded in the nu1/nu4 region from 2075 to 2315 cm-1 at an optical resolution of 2.3 x 10(-3) cm-1. The nu1/nu4 fundamental bands and the (nu1 + nu3) - nu3/(nu4 + nu3) - nu3 hot bands have been rotationally investigated. Numerous local perturbations have been observed in the nu1 and nu4 bands and in the hot bands. Without the lines involved in perturbations, more than 2900 transitions of the nu1/nu4 bands were used to determine the band origins and the vibration-rotation parameters of the nu1 = 1 and nuv4 = 1 states. A least-squares fit of 766 apparently unperturbed transitions of the hot bands gave the parameters of the nu1 = nu3 = 1 and nu4 = nu3 = 1 states. The l(2, 2) resonance in nu4 and the A1-E Coriolis coupling between nu1 and nu4 have been investigated. Most of the local perturbations have been studied individually using a simple model by which the main perturber for each resonance was identified. Copyright 1998 Academic Press.     

Long-term outcome in cognitive-behavioral treatment of panic disorder: Clinical predictors and alternative strategies for assessment.

Long-term outcome (24-month follow-up; 24 MFU) of cognitive-behavioral treatment was examined in 63 patients with panic disorder. When the traditional methods of cross-sectional assessment were used (e.g., panic frequency during past month), long-term outcome findings paralleled those of earlier studies. However, assessments of idiographic response and those that examined longer time periods revealed that a large proportion of the sample experienced a fluctuating symptom course of panic-related symptomatology that was not captured by the cross-sectional method. Many (27%) patients sought further treatment for panic during the follow-up period because of a less-than-adequate response to treatment; nevertheless, additional treatment did not result in further clinical improvement. Pretreatment severity of panic disorder was associated with poorer outcome at 24 MFU. Use of psychotropic medication during treatment was associated with poorer outcome, although to a weaker degree when pretreatment responding was controlled. Findings are discussed in the context of how the outcome of treatments for panic disorder should be evaluated and interpreted. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effects of treatment compliance on outcome in cognitive-behavioral therapy for panic disorder: Quality versus quantity.

Cognitive-behavioral therapy (CBT) is skill based and assumes active patient participation in regard to treatment-related assignments. The effects of patient compliance in CBT outcome studies are equivocal, however, and 1 gap in the literature concerns the need to account for the quality versus the quantity of assigned work. In this study, both quality and quantity of home-based practice were assessed to better evaluate the effects of treatment compliance in patients with panic disorder (N?=?48) who participated in a 12-session CBT protocol. Patient estimates of compliance were not significantly associated with most outcome measures. On the other hand, therapist ratings of compliance significantly predicted positive changes on most outcome measures. Moreover, therapist and independent rater estimates of the quality of the participant's work, relative to the quantity of the work, were relatively better predictors of outcome.

Patient dropout from a couples' group treatment for panic disorder with agoraphobia.

This study examined premature termination from couples' group treatment for panic disorder with agoraphobia. Patients were classified as either treatment noncompleters or treatment completers. Comparisons of pretreatment self-report and clinician-rated measures of anxiety and depression indicated no differences between groups. On communication measures, however, partners of noncompleters rated themselves as less communicative about panic-related issues. Of noncompleters, the majority reported "getting to treatment sessions" as problematic and indicated dissatisfaction with the cognitive-behavioral treatment approach. Results are discussed in terms of these issues and their impact on the treatment of these patients. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effectiveness of cognitive-behavioral treatment for panic disorder versus treatment as usual in a managed care setting: 2-year follow-up.

Eighty clients meeting criteria for panic disorder and receiving either panic control therapy (PCT; M. G. Craske, E. Meadows, & D. H. Barlow, 1994) or treatment as usual (TAU) in a managed care setting were assessed 1 and 2 years following acute treatment. PCT was provided by therapists with little or no previous exposure to cognitive-behavioral therapies. Analyses of the full intent-to-treat sample revealed no significant differences between the treatments across the follow-up period. However, when treatment completer status was added as a moderator, those receiving PCT showed lower levels of panic severity and phobic avoidance and a greater likelihood of achieving and maintaining clinically significant change. Benzodiazepine use during follow-up was associated with greater panic severity for those clients who received PCT, but no such relationship was found for TAU clients. Results are discussed in relation to the dissemination and effectiveness of PCT as well as evidence-based psychotherapies more generally.

Cognitive-behavioral treatment of panic disorder.

Cognitive-behavioral therapy can be effective for many clients with panic disorder. Therapy can be conceptualized in terms of four central components. First, the initial preparation for therapy involves establishing a working alliance, educating the client about panic symptoms and treatments, and conducting a diagnostic assessment. Second, skills training is used to cultivate active coping skills that the client can use to tolerate symptoms of emotional distress. Third, exposure is used to encourage clients to test and refine their newly developed coping skills. Fourth, relapse prevention is used to help clients discontinue psychological and biological treatments without suffering lasting setbacks. Through the use of cognitive-behavioral therapy, most clients can learn to control their symptoms of panic and reduce their anticipatory anxiety. Treatment gains can be maintained after therapy is discontinued. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Catastrophic misinterpretations as a predictor of symptom change during treatment for panic disorder.

Objective: Cognitive models of panic disorder suggest that change in catastrophic misinterpretations of bodily sensations will predict symptom reduction. To examine change processes, we used a repeated measures design to evaluate whether the trajectory of change in misinterpretations over the course of 12-week cognitive behavior therapy is related to the trajectory of change in a variety of panic-relevant outcomes. Method: Participants had a primary diagnosis of panic disorder (N = 43; 70% female; mean age = 40.14 years). Race or ethnicity was reported as 91% Caucasian, 5% African American, 2.3% biracial, and 2.3% “other.” Change in catastrophic misinterpretations (assessed with the Brief Body Sensations Interpretation Questionnaire; Clark et al., 1997) was used to predict a variety of treatment outcomes, including overall panic symptom severity (assessed with the Panic Disorder Severity Scale [PDSS]; Shear et al., 1997), panic attack frequency (assessed with the relevant PDSS item), panic-related distress/apprehension (assessed by a latent factor, including peak anxiety in response to a panic-relevant stressor—a straw breathing task), and avoidance (assessed by a latent factor, which included the Fear Questionnaire–Agoraphobic Avoidance subscale; Marks & Mathews, 1979). Results: Bivariate latent difference score modeling indicated that, as expected, change in catastrophic misinterpretations predicted subsequent reductions in overall symptom severity, panic attack frequency, distress/apprehension, and avoidance behavior. However, change in the various symptom domains was not typically a significant predictor of later interpretation change (except for the distress/apprehension factor). Conclusions: These results provide considerable support for the cognitive model of panic and speak to the temporal sequence of change processes during therapy.

A comparison of bibliotherapy and group therapy in the treatment of panic disorder.

Investigated 2 methods of disseminating a cognitive-behavioral intervention for panic disorder (PD). 36 Ss who met diagnostic criteria for PD were randomly assigned to 1 of 3 conditions: bibliotherapy (BT), group therapy (GT), or a waiting-list control (WL) condition. Results show that both the BT and GT treatments were more effective than the WL condition in reducing frequency of panic attacks, severity of physical panic symptoms, catastrophic cognitions, agoraphobic avoidance, and depression and that the BT and GT treatments were more effective in increasing self-efficacy.

The role of trauma and dissociation in cognitive-behavioral psychotherapy outcome and maintenance for panic disorder with agoraphobia

The relationship between traumatic experiences and dissociation with pretreatment psychopathology and rates of recovery, relapse and maintenance for patients receiving cognitive-behavioral treatments for panic disorder with agoraphobia (PDA) were investigated. One-hundred and forty-seven subjects who met DSM-III criteria for agoraphobia with panic attacks and who completed participation in one of two previously conducted treatment outcome studies were mailed packets containing measures to assess history of trauma, victimization and dissociation. Eighty-nine of these were returned and completed sufficiently to be included in the present study. It was hypothesized that a variety of trauma-related variables (e.g. history of traumatic experience, type of trauma, age at which the trauma first occurred, perceived responsibility, social supports available, self-perceived severity, level of violence, and whether or not the traumatic event was followed by self-injurious or suicidal thoughts and/or behaviors) and dissociative symptomatology would be predictive of (1) greater psychopathology at pretreatment, (2) poorer treatment response and (3) higher relapse rates and poorer maintenance over a 1 year longitudinal follow-up. These hypotheses were supported by the findings and the theoretical, empirical and clinical implications are discussed.     

Therapists, therapist variables, and cognitive-behavioral therapy outcome in a multicenter trial for panic disorder.

The relationship between therapists and treatment outcome was examined in 14 highly trained therapists who participated in the Multicenter Collaborative Study for the Treatment of Panic Disorder. Overall, therapists yielded positive outcomes in their caseloads; yet, therapists significantly differed in the magnitude of change among caseloads. Effect sizes for therapist impact on outcome measures varied from 0% to 18%. Overall experience in conducting psychotherapy was related to outcome on some measures, whereas age, gender, gender match, and experience with cognitive-behavioral therapy (CBT) were not. Therapists with above- and below-average outcomes were rated similarly on measures of adherence and competency. The results suggest that therapists make a contribution to outcome in CBT for panic disorder, even when patients are relatively uniform, treatment is structured, and outcome is positive. Implications for future clinical outcome studies and for training clinicians are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A cognitive-behavioral treatment for impulsivity: A group comparison study.

From a clinic population of emotionally disturbed children, 20 children initially identified as impulsive were randomly assigned to either a cognitive-behavioral treatment group (mean age 10.2 yrs) or to a control group (mean age 11.1 yrs). The treatment group received 6 sessions of verbal self-instructions via modeling with response-cost contingent on errors during training, and controls received similar training without specific treatment. Although 2 self-report measures and teacher and staff ratings of locus of conflict did not show treatment effects, an increase in the latency and decrease in the error measures from the Matching Familiar Figures Test, and improved teacher ratings of impulsive classroom behavior revealed positive effects due to treatment. These effects remained evident at 3-mo follow-up. This study provides group-comparison evidence for the efficacy of the cognitive-behavioral treatment for modifying impulsivity.

A clinical study of autogenic training-based behavioral treatment for panic disorder

The present study investigated the effect of autogenic training-based behavioral treatment for panic disorder and identified the predictors of treatment outcome. Thirty-four patients meeting DSM-III-R criteria for panic disorder received autogenic training-based behavioral treatment from October 1981 to December 1994. They were treated individually by the author. The medical records of the patients were investigated for the purpose of this study. The results showed that this autogenic training-based behavioral treatment had successful results. Fifteen patients were cured, nine much improved, five improved, and five unchanged at the end of the treatment. Improvement trends were found as for the severity of panic attack and the severity of agoraphobic avoidance. No consistent findings about predictors emerged when such pretreatment variables as demographics and severity of symptoms were used to predict the outcome. Also, three treatment variables showed useful predictive power. First, practicing the second standard autogenic training exercise satisfactorily predicted better outcomes. Second, application of in vivo exposure was found to be positively associated with the treatment outcome in patients with agoraphobic avoidance. Third, longer treatment periods were associated with better outcomes. These findings suggested that the autogenic training-based behavioral treatment could provide relief to the majority of panic disorder patients.     

Decreased plasma cortisol level during alprazolam treatment of panic disorder: a case report

OBJECTIVE: Our goal was to evaluate the impact of fetal compromise on the outcome of borderline viable babies. STUDY DESIGN: All 142 babies born in our hospital from 1990 to 1995 with a gestational age of 23 to 25 weeks were included. Fetal compromise was considered present if one of the following was documented: a major anomaly, congenital sepsis, chronic intrauterine infection, intrauterine drug exposure, congenital anemia, severe growth restriction, fetal acidosis, or cardiorespiratory and neurologic depression in the delivery room. RESULTS: The 43 babies who had at least one cause of fetal compromise had a lower birth weight (p < 0.001), but there were no other differences in demographics or complications of prematurity. The survival rate was significantly better for babies free of fetal compromise (75% vs 33%, p < 0.001), particularly for babies born at 23 weeks of gestation (75% vs 6%, p < 0.001). For surviving babies free of fetal compromise, the outcome at 23 weeks was comparable to that at 24 to 25 weeks for major causes of long-term neurologic morbidity. CONCLUSIONS: Like advancing gestational age and increasing birth weight, the absence of fetal compromise has a major beneficial impact on the outcome of borderline viable babies that might be important when decisions are made about the appropriate level of support.     

Methodological controversies in the treatment of panic disorder.

Although the National Institutes of Health Consensus Development Conference on the Treatment of Panic Disorder endorsed the effectiveness of cognitive–behavior therapy (CBT), D. E. Klein (see record 1996-02770-008) argues that fatal flaws in all but one (negative) CBT study undermine claims about the effectiveness of CBT for panic disorder. He holds that methodologically sound CBT trials must include a drug condition and a pill placebo condition and must demonstrate the superiority of drug versus placebo; otherwise researchers are debarred from making comparative statements about the effectiveness of CBT versus drug (or placebo). The purpose of the present article is to provide a critique of Klein's arguments and to provide suggestions for resolving methodological disputes in the panic disorder field.
