3D printable adhesive elastomers with dynamic covalent bond rearrangement.

Repairable adhesive elastomers are emerging materials employed in compelling applications such as soft robotics, biosensing, tissue regeneration, and wearable electronics. Facilitating adhesion requires strong interactions, while self-healing requires bond dynamicity. This contrast in desired bond characteristics presents a challenge in the design of healable adhesive elastomers.

Development and Initial Validation of a Brief Questionnaire on the Patients' View of the In-Session Realization of the Six Core Components of Acceptance and Commitment Therapy.

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).

Evaluation of the contribution of values clarification to a brief mindfulness meditation intervention for anxiety.

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; M  = 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.

Long-term outcome of a mental health promotion program in Germany.

Mental health promotion programs (MHP) seek to reduce sub-syndromal symptoms of mental distress and enhance positive mental health. This study evaluates the long-term effects of a mindfulness-based MHP program ('Life Balance') provided by health coaches in a multi-site field setting on mental distress, satisfaction with life and resilience. Using a controlled design, propensity score matching was used to select a control group for participants of the MHP.

Increasing valued behaviors precedes reduction in suffering: Findings from a randomized controlled trial using ACT.

Background: Psychological flexibility theory (PFT) suggests three key processes of change: increases in value-directed behaviors, reduction in struggle with symptoms, and reduction in suffering. We hypothesized that Acceptance and Commitment Therapy (ACT) would change these processes and that increases in valued action and decreases in struggle would precede change in suffering.

Method: Data were derived from a randomized clinical trial testing ACT (vs.

Evaluating the Effectiveness of ACT for Anxiety Disorders in a Self-Help Context: Outcomes From a Randomized Wait-List Controlled Trial.

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).

Life Balance - a mindfulness-based mental health promotion program: conceptualization, implementation, compliance and user satisfaction in a field setting.

Background: Mental health disorders account for a large percentage of the total burden of illness and constitute a major economic challenge in industrialized countries. Several prevention programs targeted at high-risk or sub-clinical populations have been shown to decrease risk, to increase quality of life, and to be cost-efficient. However, there is a paucity of primary preventive programs aimed at the general adult population.

Treating Treatment-Resistant Patients with Panic Disorder and Agoraphobia Using Psychotherapy: A Randomized Controlled Switching Trial.

Background: Nonresponsiveness to therapy is generally acknowledged, but only a few studies have tested switching to psychotherapy. This study is one of the first to examine the malleability of treatment-resistant patients using acceptance and commitment therapy (ACT). Methods: This was a randomized controlled trial that included 43 patients diagnosed with primary panic disorder and/or agoraphobia (PD/A) with prior unsuccessful state-of-the-art treatment (mean number of previous sessions = 42.

Brazilian Portuguese validated version of the Cardiac Anxiety Questionnaire.

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.

Longitudinal treatment mediation of traditional cognitive behavioral therapy and acceptance and commitment therapy for anxiety disorders.

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 < .

Randomized clinical trial of cognitive behavioral therapy (CBT) versus acceptance and commitment therapy (ACT) for mixed anxiety disorders.

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.

The Believability of Anxious Feelings and Thoughts Questionnaire (BAFT): a psychometric evaluation of cognitive fusion in a nonclinical and highly anxious community sample.

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.

Biological sex and panic-relevant anxious reactivity to abrupt increases in bodily arousal as a function of biological challenge intensity.

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.

Cardiophobia: a critical analysis.

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.

Heart-focused anxiety before and after cardiac surgery.

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.

Taxonicity of anxiety sensitivity: a multi-national analysis.

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.

Avoidance-oriented coping as a predictor of panic-related distress: a test using biological challenge.

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.

The effects of acceptance versus control contexts on avoidance of panic-related symptoms.

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).

The effects of anxious responding on mental arithmetic and lexical decision task performance.

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.

Contemporary behavioral activation treatments for depression: procedures, principles, and progress.

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.

Offset control during recurrent 20% carbon dioxide-enriched air induction: relation to individual difference variables.

Although control over aversive events maintains a central role in contemporary models of anxiety pathology, particularly panic disorder, there is little understanding about the emotional consequences of specific types of control processes. In the present study, offset control over 8 20% carbon dioxide-enriched air administrations was experimentally manipulated in a large nonclinical population (n = 96) varying in anxiety sensitivity (high or low) and gender. Dependent measures included self-reported anxiety, affective reports of valence, arousal, emotional control, and physiological indices of heart rate and skin conductance.

Heart-focused anxiety and chest pain in postangiography medical patients.

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.

Anxiety sensitivity in six countries.

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.
