RESUMO

Background: Assessing in-session processes is important in psychotherapy research. The aim of the present study was to create and evaluate a short questionnaire capturing the patients' view of the in-session realization of the six core components of Acceptance and Commitment Therapy (ACT). Method: In two studies, psychotherapy patients receiving ACT (Study 1: n = 87) or Cognitive-Behavioral Therapy (CBT) (Study 2, Sample 1: n = 115; Sample 2: n = 156) completed the ACT session questionnaire (ACT-SQ). Therapists were n = 9 ACT therapists (Study 1) and n = 77 CBT trainee therapists (Study 2). Results: Factor structure: Exploratory factor analyses suggested a one-factor solution for the ACT-SQ. Reliability: Cronbach's alpha of the ACT-SQ was good (Study 1: α = .81; Study 2, Sample 1: α = .84; Sample 2: α = .88). Convergent validity: The ACT-SQ was positively correlated with validated psychotherapeutic change mechanisms (p < .05). Criterion validity: Higher ACT-SQ scores were associated with better treatment outcomes (p < .05). Conclusion: The study provides preliminary evidence for the reliability and validity of the ACT-SQ to assess the in-session realization of the six core components of ACT in the patients' view. Further validation studies and ACT-SQ versions for therapists and observers are necessary.

RESUMO

OBJECTIVE: Evaluate the incremental effects of a computerized values clarification (VC) activity on anxiety symptomology and quality of life over and above establishment of a mindfulness meditation (MM) practice. METHOD: Anxious participants (N = 120, Female = 86; Mage  = 22.26) were randomly assigned to a 2-week, 10-min daily MM practice + control task or a 2-week, 10-min daily MM practice + VC task. Pre-assessments and post-assessments included well-established and ideographic self-report measures. RESULTS: Overall decreases in past week and past 24-h anxiety symptom frequency, as well as increased quality of life during the previous 24-h cycle only. VC did not have a demonstrable impact on outcomes. CONCLUSIONS: Though findings are preliminary, brief VC exercises may not enhance outcomes that follow from mindfulness practice. Additional research is needed to isolate specific and shared impacts of mindfulness-based and values-based treatment strategies on anxiety symptoms and quality of life.

RESUMO

Rigorous evaluations of cognitive behavioral self-help books for anxiety in pure self-help contexts are lacking. The present study evaluated the effectiveness of an Acceptance and Commitment Therapy (ACT) self-help workbook for anxiety-related concerns, with no therapist contact, in an international sample. Participants (N=503; 94% mental health diagnosis) were randomized to an immediate workbook (n=256) or wait-list condition (n=247). Assessments at pretreatment, 12weeks, 6months, and 9months evaluated anxiety and related symptoms, quality of life, and ACT treatment processes (e.g., psychological flexibility). Participants in the wait-list arm crossed over to the workbook following the 12-week assessment. The workbook condition yielded significant improvements on all assessments from pre- to posttreatment relative to wait-list, and these gains were maintained at follow-ups. The pattern observed in the wait-list condition was virtually identical to the active treatment arm after receiving the workbook, but not before. Attrition was notable, but supplemental analyses suggested dropout did not influence treatment effects for all but one measure. Overall, findings provide preliminary support for the effectiveness of this self-help workbook and suggest ACT-based self-help bibliotherapy might be a promising low-cost intervention for people experiencing significant anxiety-related concerns.

RESUMO

FUNDAMENTOS: A ansiedade cardíaca (AC) é o medo de sensações cardíacas, caracterizado por sintomas recorrentes de ansiedade em pacientes com ou sem doença cardiovascular. O Questionário de Ansiedade Cardíaca (QAC) é uma ferramenta para avaliar a AC, já adaptado, mas não validado em português. OBJETIVO: Este trabalho apresenta as três fases dos estudos de validação do QAC brasileiro. MÉTODOS: Foram recrutados 98 pacientes com doença arterial coronária, a fim de extrair a estrutura fatorial e avaliar a confiabilidade do QAC (fase 1). O objetivo da fase 2 foi explorar a validade convergente e divergente. Cinquenta e seis pacientes completaram o QAC, juntamente com o Escala de sensações corporais (ESC) e o Versão brasileira do Social Phobia Inventory (SPIN). Para determinar a validade discriminante (fase 3), comparamos os escores do QAC de dois subgrupos formados por pacientes da fase 1 (n = 98), de acordo com os diagnósticos de transtorno do pânico e agorafobia obtidos com o MINI - Mini International Neuropsychiatric Interview (Mini Entrevista Neuropsiquiátrica Internacional). RESULTADOS: A solução de dois fatores foi a mais interpretável (46,4% da variância). As subescalas foram denominadas de "Medo e Hipervigilância" (n = 9; alfa = 0,88) e "Evitação" (n = 5; alfa = 0,82). Foi encontrada correlação significativa do fator 1 com o escore total do ESC (p < 0,01), mas não com o fator 2. Os fatores do SPIN apresentaram correlações significativas com as subescalas do QAC (p < 0,01). Na fase 3, os escores dos pacientes "Cardíacos com pânico" foram significativamente maiores no fator 1 do QAC (t = -3,42; p < 0,01, IC = -1,02 a -0,27), e maiores, mas não significativamente diferentes, no fator 2 (t = -1,98; p = 0,51, IC = -0.87 a 0,00). CONCLUSÕES: Os presentes resultados fornecem uma versão final brasileira validada do QAC adequada aos contextos clínicos e de pesquisa.


BACKGROUND: Cardiac Anxiety (CA) is the fear of cardiac sensations, characterized by recurrent anxiety symptoms, in patients with or without cardiovascular disease. The Cardiac Anxiety Questionnaire (CAQ) is a tool to assess CA, already adapted but not validated to Portuguese. OBJECTIVE: This paper presents the three phases of the validation studies of the Brazilian CAQ. METHODS: To extract the factor structure and assess the reliability of the CAQ (phase 1), 98 patients with coronary artery disease were recruited. The aim of phase 2 was to explore the convergent and divergent validity. Fifty-six patients completed the CAQ, along with the Body Sensations Questionnaire (BSQ) and the Social Phobia Inventory (SPIN). To determine the discriminative validity (phase 3), we compared the CAQ scores of two subgroups formed with patients from phase 1 (n = 98), according to the diagnoses of panic disorder and agoraphobia, obtained with the MINI - Mini International Neuropsychiatric Interview. RESULTS: A 2-factor solution was the most interpretable (46.4% of the variance). Subscales were named "Fear and Hypervigilance" (n=9; alpha = 0.88), and "Avoidance", (n = 5; alpha = 0.82). Significant correlation was found between factor 1 and the BSQ total score (p<0.01), but not with factor 2. SPIN factors showed significant correlations with CAQ subscales (p < 0.01). In phase 3, "Cardiac with panic" patients scored significantly higher in CAQ factor 1 (t = -3.42; p < 0.01, CI = -1.02 to -0.27), and higher, but not significantly different, in factor 2 (t = -1.98; p = 0.51, CI = -0.87 to 0.00). CONCLUSIONS: These results provide a definite Brazilian validated version of the CAQ, adequate to clinical and research settings.

RESUMO

OBJECTIVE: To assess the relationship between session-by-session putative mediators and treatment outcomes in traditional cognitive behavioral therapy (CBT) and acceptance and commitment therapy (ACT) for mixed anxiety disorders. METHOD: Session-by-session changes in anxiety sensitivity and cognitive defusion were assessed in 67 adult outpatients randomized to CBT (n = 35) or ACT (n = 32) for a DSM-IV anxiety disorder. RESULTS: Multilevel mediation analyses revealed significant changes in the proposed mediators during both treatments (p < .001, d = .90-1.93), with ACT showing borderline greater improvements than CBT in cognitive defusion (p = .05, d = .82). Anxiety sensitivity and cognitive defusion both significantly mediated post-treatment worry; cognitive defusion more strongly predicted worry reductions in CBT than in ACT. In addition, cognitive defusion significantly mediated quality of life, behavioral avoidance, and (secondary) depression outcomes across both CBT and ACT (p < .05, R(2) change = .06-.13), whereas anxiety sensitivity did not significantly mediate other outcomes. CONCLUSIONS: Cognitive defusion represents an important source of therapeutic change across both CBT and ACT. The data offered little evidence for substantially distinct treatment-related mediation pathways.

RESUMO

OBJECTIVE: Randomized comparisons of acceptance-based treatments with traditional cognitive behavioral therapy (CBT) for anxiety disorders are lacking. To address this gap, we compared acceptance and commitment therapy (ACT) to CBT for heterogeneous anxiety disorders. METHOD: One hundred twenty-eight individuals (52% female, mean age = 38, 33% minority) with 1 or more DSM-IV anxiety disorders began treatment following randomization to CBT or ACT; both treatments included behavioral exposure. Assessments at pre-treatment, post-treatment, and 6- and 12-month follow-up measured anxiety-specific (principal disorder Clinical Severity Ratings [CSRs], Anxiety Sensitivity Index, Penn State Worry Questionnaire, Fear Questionnaire avoidance) and non-anxiety-specific (Quality of Life Index [QOLI], Acceptance and Action Questionnaire-16 [AAQ]) outcomes. Treatment adherence, therapist competency ratings, treatment credibility, and co-occurring mood and anxiety disorders were investigated. RESULTS: CBT and ACT improved similarly across all outcomes from pre- to post-treatment. During follow-up, ACT showed steeper linear CSR improvements than CBT (p < .05, d = 1.26), and at 12-month follow-up, ACT showed lower CSRs than CBT among completers (p < .05, d = 1.10). At 12-month follow-up, ACT reported higher AAQ than CBT (p = .08, d = 0.42; completers: p < .05, d = 0.56), whereas CBT reported higher QOLI than ACT (p < .05, d = 0.42). Attrition and comorbidity improvements were similar; ACT used more non-study psychotherapy at 6-month follow-up. Therapist adherence and competency were good; treatment credibility was higher in CBT. CONCLUSIONS: Overall improvement was similar between ACT and CBT, indicating that ACT is a highly viable treatment for anxiety disorders.

RESUMO

Cognitive fusion--or the tendency to buy into the literal meaning of thoughts, feelings, and bodily sensations--plays an important role in the etiology and maintenance of anxiety disorders and figures prominently in third-generation behavior therapies such as acceptance and commitment therapy (ACT). Nonetheless, there is a lack of validated self-report measures of cognitive fusion/defusion, particularly in the area of anxiety disorders. We attempted to fill this gap with the development and validation of a self-report cognitive fusion measure, the Believability of Anxious Feelings and Thoughts Questionnaire (BAFT), in both a healthy undergraduate sample (N = 432) and highly anxious community sample (N = 503) undergoing a 12-week online ACT intervention. Results suggested a hierarchical factor structure of the BAFT with three lower order factors and one hierarchical factor and excellent internal consistency for the total BAFT score (i.e., αs = .90 and .91 for the undergraduate and highly anxious samples, respectively) and for its factors. Additionally, the BAFT and all of its factors consistently showed strong construct validity with other relevant process and outcome measures in both samples, strong 12-week test-retest reliability (r = .77) in our highly anxious waitlist control subsample and responsiveness to treatment in our highly anxious intervention subsample. These findings suggest that the BAFT is a reliable and valid measure of cognitive fusion in both healthy and clinical populations.

RESUMO

An emerging pattern of results from panic-relevant biological challenge studies suggests women respond with greater subjective anxiety than men, but only to relatively abrupt and intense challenge procedures. The current investigation examined the relation between biological sex and self-reported anxious reactivity following biological challenges of varying durations and intensity. Participants were 285 (152 females; M(age) = 21.38; SD = 5.92) nonclinical adults who completed one of three protocols: a 3-min voluntary hyperventilation challenge (VH), a 5-min 10% carbon dioxide-enriched air (CO(2)) challenge, or a 25-s 20% CO(2) challenge. As predicted, results indicated that the 20% CO(2) challenge elicited greater self-reported anxiety than the VH and 10% CO(2) challenges. Moreover, women endorsed greater anxious reactivity than men, but only following the 20% CO(2) challenge. Results are discussed in terms of processes likely to account for sex differences in anxious reactivity following relatively abrupt and intense biological challenges.

RESUMO

INTRODUÇÃO: É crescente a produção científica brasileira na adaptação de instrumentos internacionais para avaliar ansiedade. A tradução e adaptação transcultural de escalas é um primeiro passo na obtenção de instrumentos válidos que permitam a comparação de diferentes populações. O objetivo do presente estudo foi traduzir e avaliar a equivalência semântica do Cardiac Anxiety Questionnaire, realizando um estudo piloto na população brasileira de diferentes níveis de escolaridade. MÉTODO: O processo de adaptação transcultural envolveu duas traduções e retrotraduções realizadas por avaliadores independentes, avaliação das versões e elaboração de uma versão síntese. Também examinamos os comentários dos participantes sobre a versão preliminar do questionário, os quais foram usados no desenvolvimento da versão final. RESULTADOS: Para cada item do instrumento, apresentam-se os resultados das quatro etapas. Os participantes com maior grau de escolaridade não apresentaram dificuldades na compreensão do instrumento, tendo apenas apresentado sugestões controversas acerca do item 5. Entretanto, os participantes apenas com escolaridade em nível fundamental relataram dificuldades com os itens 2, 4, 6, 7, 10, 11 e 14. Algumas alterações semânticas foram realizadas com o intuito de facilitar a compreensão do instrumento. CONCLUSÃO: A utilização de duas versões de tradução e retrotradução, discussão sobre a versão síntese e a interlocução com a população-alvo proporcionaram maior segurança ao processo de equivalência semântica da versão final brasileira.


INTRODUCTION: There has been a growing interest in the cross-cultural application of psychological questionnaires to assess anxiety. The translation and cross-cultural adaptation of the original instrument is the first step in validating an instrument in a new population that will permit comparisons between different populations. The goals of this study were to translate the Cardiac Anxiety Questionnaire, assess its semantic equivalence, and perform a preliminary test with participants from the Brazilian population that were drawn from different educational backgrounds. METHOD: The cross-cultural adaptation process consisted of two translations and back translations performed by two independent evaluators; a critical evaluation of the two versions, and the development of a synthesized version. We also examined comments provided by participants on the preliminary version of the questionnaire and used them for the development of the final version. RESULTS: We report the results of the four stages for each item of the instrument. Participants with tertiary education had no difficulties comprehending the translated items of the questionnaire, only pointing item 5 as ambiguous. Participants from the lower educational level reported comprehension problems regarding items 2, 4, 6, 7, 10, 11 and 14. Some small changes were made in our first version to enhance comprehensibility. CONCLUSION: The use of two versions of translations, a critical examination of the two versions, and suggestions made by participants resulted in a final Brazilian version with a satisfactory degree of semantic accuracy and semantic equivalence with the original version.

RESUMO

Cardiophobia, a clinical syndrome that affects hundreds of thousands of individuals in the USA, is characterized by abrupt, recurrent sensations and pain in the chest in the absence of physical pathology. This conceptual article seeks to address the significance of cardiophobia in western culture and to distinguish it from related disorders. In addition, a model of cardiophobia that highlights the role of heart-focused anxiety and interoceptive conditioning in the generation of limited-symptom panic attacks and acute chest pain is presented and vulnerability factors for cardiophobia are discussed. Future research directions relevant to the assessment and treatment of this clinically significant phenomenon are reviewed.

RESUMO

OBJECTIVE: We investigated the degree and course of heart-focused anxiety (HFA) in patients with cardiac diseases before and after cardiac surgery. METHODS: We examined 90 patients undergoing coronary bypass, valve replacement, or combined surgery before surgery, 6 weeks after surgery, and 6 months after surgery. Patients completed the Cardiac Anxiety Questionnaire (CAQ), which assesses heart-focused fear, attention, and avoidance, and a set of other questionnaires assessing general anxiety, depression, and quality of life. Data were compared with an age- and sex-controlled contrast group of 72 orthopedic patients with no history of cardiac disease. RESULTS: All dimensions of HFA were elevated in patients before surgery. CAQ-Fear was significantly reduced 6 weeks after surgery and at 6-month follow-up. CAQ-Avoidance was stable after surgery but declined on follow-up, while there was only a statistical tendency indicating reduction in CAQ-Attention. Approximately 20% of patients continued to experience clinically elevated levels of HFA at 6-month follow-up. Furthermore, we found decreases in global anxiety and depression, and an increase in quality of life after surgery. CONCLUSIONS: In contrast to global psychosocial indicators, the more specific assessment of HFA may help identify individuals with elevated levels of HFA who might benefit from interventions to help them adjust to the effects of surgery and lingering cardiac problems.

RESUMO

Taxometric coherent cut kinetic analyses were used to test the latent structure of anxiety sensitivity in samples from North America (Canada and United States of America), France, Mexico, Spain, and The Netherlands (total n = 2741). Anxiety sensitivity was indexed by the 36-item Anxiety Sensitivity Index--Revised (ASI-R; [J. Anxiety Disord. 12(5) (1998) 463]). Four manifest indicators of anxiety sensitivity were constructed using the ASI-R: fear of cardiovascular symptoms, fear of respiratory symptoms, fear of publicly observable anxiety reactions, and fear of mental incapacitation. Results from MAXCOV-HITMAX, internal consistency tests, analyses of simulated Monte Carlo data, and a MAMBAC external consistency test indicated that the latent structure of anxiety sensitivity was taxonic in each of the samples. The estimated base rate of the anxiety sensitivity taxon differed slightly between nations, ranging from 11.5 to 21.5%. In general, the four ASI-R based manifest indicators showed high levels of validity. Results are discussed in relation to the conceptual understanding of anxiety sensitivity, with specific emphasis on theoretical refinement of the construct.

RESUMO

The present experimental psychopathology study sought to investigate the extent to which pre-experimental levels of avoidance-oriented coping predict anxious and fearful responding during acute physical stress, relative to other theoretically relevant variables. Participants included 80 individuals with no known history of psychological or physical health problems. Dependent measures include self-reported anxiety, DSM-IV panic symptoms, and physiological indices of heart rate and skin conductance. Consistent with our hypotheses, the tendency to engage in avoidance-oriented coping predicted increased physical panic symptoms and self-reported anxiety elicited by biological challenge, relative to specific anxiety sensitivity (AS) dimensions. These findings are discussed in terms of how specific types of coping are associated with prototypical indices of panic distress, with implications for forwarding future work on emotional regulation in panic disorder.

RESUMO

Anxiety-related responding and skill deficits historically are associated with performance-based problems such as mathematics anxiety, yet the relative contribution of these variables to substandard performance remains poorly understood. Utilizing a 7% carbon dioxide (CO2) gas to induce anxiety, the present study examined the impact of anxious responding on two performance tasks, mental arithmetic and lexical decision. Independent variables included math anxiety group, gender, and gas condition. Dependent variables included task performance and physiological and self-report indices of anxiety. A total of 64 university undergraduate students participated. Physiological and verbal-report measures of anxiety supported the utility of 7% carbon dioxide-enriched air as an anxiety-inducing stimulus. Behavioral disruption on performance tasks, however, did not differ as a function of carbon dioxide inhalation. Performance did differ as a function of math anxiety. High math anxious individuals generally exhibited higher error rates on mathematical tasks, particularly on tasks designed to measure advanced math skill and those requiring working memory resources. These findings are discussed with reference to processing efficiency theory, discordance among anxiety response systems, and the intricacies associated with skill measurement.

RESUMO

In the past decade, there has been renewed interest in the feasibility and efficacy of purely behavioral treatments for clinical depression. Emphasizing the functional aspects of depressive and nondepressive behavior, these treatments focus on the concept of behavioral activation, which guides implementation of procedures aimed at increasing patient activity and access to reinforcement. Although researchers have provided positive preliminary support for behavioral activation-based interventions, many fundamental issues concerning strategies, principles, and change processes involved in behavioral activation have yet to be addressed. In this paper, we compare and contrast contemporary behavioral activation interventions, explore strategies and process of change issues, clarify the basic behavioral principles underlying activation strategies, and outline questions that need to be addressed to improve outcomes and better understand the potential significance of behavioral activation as it pertains to the future of behavior therapy for depression.

RESUMO

The present cross-sectional study sought to examine the extent to which heart-focused anxiety is associated with the co-occurrence of coronary artery disease (CAD) and a history of regular smoking in a sample of 148 postangiography patients from a cardiology unit. Individuals with CAD who regularly smoked demonstrated significantly greater heart-focused attention, but no greater degree of avoidance and fear of heart-focused sensations, than did nonsmoking persons with CAD and smokers without CAD. We also found evidence that heart-focused attention and fear incrementally predicted (above and beyond demographic variables and body mass index) intensity of average chest pain. Overall, this study provides some of the first empirical evidence that the occurrence of regular smoking and CAD is associated with specific dimensions of health anxiety. We discuss these findings in relation to models of panic pathology and anxious responding to bodily sensations.

RESUMO

In the present study, the Anxiety Sensitivity Index-Revised (ASI-R; ) was administered to a large sample of persons (n=2786) from different cultures represented in six different countries: Canada, France, Mexico, The Netherlands, Spain, and the United States. We sought to (a) determine the factor structure and internal consistency of the ASI-R and (b) examine the correlations of the measure with psychiatric symptoms and personality dimensions in a single European non-English speaking country (The Netherlands). Partially consistent with the original hypothesis, the underlying structure of the anxiety sensitivity construct was generally similar across countries, tapping fear about the negative consequences of anxiety-related physical and social-cognitive sensations. Lower-order factors were moderately to strongly correlated with one another and showed good internal consistency. The observed lower-order ASI-R factors correlated with established psychiatric symptoms and with the personality trait of neuroticism. Partial correlations indicated that both factors are useful in accounting for variance in symptom measures. We discuss the results of this investigation in relation to the cross-cultural assessment of the anxiety sensitivity construct.

RESUMO

The present study compared the effects of creating an acceptance versus a control treatment context on the avoidance of aversive interoceptive stimulation. Sixty high anxiety sensitive females were exposed to two 10-min periods of 10% carbon dioxide enriched air, an anxiogenic stimulus. Before each inhalation period, participants underwent a training procedure aimed at encouraging them either to mindfully observe (acceptance context) or to control symptoms via diaphragmatic breathing (control context). A third group was given no particular training or instructions. We hypothesized that an acceptance rather than control context would be more useful in the reduction of anxious avoidance. Compared to control context and no-instruction participants, acceptance context participants were less avoidant behaviorally and reported less intense fear and cognitive symptoms and fewer catastrophic thoughts during the CO(2) inhalations. We discuss the implications of our findings for an acceptance-focused vs. control-focused context when conducting clinical interventions for panic and other anxiety disorders.

RESUMO

The authors examined whether motivations for drinking alcohol are associated with the anxiety-related dispositional tendencies of anxiety sensitivity, experiential avoidance, and alexithymic coping. The authors administered the Anxiety Sensitivity Index, Experiential Avoidance Scale, 20-item Toronto Alexithymia Scale, Revised Drinking Motives Questionnaire, and a demographics questionnaire to 182 university drinkers. In multiple regressions, the dispositional factors significantly predicted the risky drinking motives of coping, enhancement, and conformity. Coping and enhancement motives were significantly predicted by experiential avoidance. Conformity motives were significantly and independently predicted by anxiety sensitivity and alexithymia. The process of experiential avoidance mediated the bivariate correlation between anxiety sensitivity and coping-motivated drinking to a greater extent than did the process of alexithymic coping. The authors discuss the observed relations in regard to the psychological functions of drinking behavior that may portend the development of heavy drinking and alcohol problems in dispositionally vulnerable individuals. They also review implications for refinements of behavior therapy for problem drinkers.
