The paradox of relaxation training: Relaxation induced anxiety and mediation effects of negative contrast sensitivity in generalized anxiety disorder and major depressive disorder

Savoring changes novel positive mindset targets of GAD treatment: Optimism, prioritizing positivity, kill-joy thinking, and worry mediation

This study analyzed effects of savoring on unstudied positive mindset targets of generalized anxiety disorder (GAD) treatment (ClinicalTrials.gov: NCT05040061). 85 students with GAD were randomly assigned to one of two ecological momentary interventions (EMIs) on smartphone for seven days. The SkillJoy EMI promoted practices for savoring positive emotions. An active control EMI mirrored SkillJoy, yet did not include savoring or positive emotion. Optimism, worry, kill-joy thinking (lessening positive emotion with cognition), and prioritization of positive emotion activities and goals were assessed at pre-trial, eighth-day, post-trial, and 30th-day follow-up. Savoring was assessed pre-trial and fifth-day mid-trial. Longitudinal linear mixed models and simple slope analyses examined change between and within conditions. Bias-corrected bootstrapping path analysis examined mediation of worry change by increased savoring. SkillJoy led to significantly greater increases in both optimism and prioritizing positivity than the control from pre-trial to post-trial and pre-trial to follow-up. Both interventions significantly reduced kill-joy thinking at both timepoints with Skilljoy leading to marginally greater change at post-trial. Pre- to mid-trial increases in savoring mediated the relationships between treatment condition and reductions in worry at both post-trial and follow-up.

Treatment condition as a moderator and change in trait mindfulness as a mediator of a brief mindfulness ecological momentary intervention for generalized anxiety disorder

BACKGROUND

Theories propose that judgment of and reactivity to inner experiences are mediators of the effect of mindfulness-based interventions on generalized anxiety disorder (GAD). However, no study has tested such theories using brief, mindfulness ecological momentary intervention (MEMI). We thus tested these theories using a 14-day MEMI versus self-monitoring app (SM) control for GAD.

METHODS

Participants (N = 110) completed self-reports of trait mindfulness (Five Facet Mindfulness Questionnaire), GAD severity (GAD-Questionnaire-IV), and trait perseverative cognitions (Perseverative Cognitions Questionnaire) at prerandomization, posttreatment, and 1-month follow-up (1MFU). Counterfactual mediation analyses with temporal precedence were conducted.

RESULTS

Improvement in pre-post mindfulness domains (acceptance of emotions, describing feelings accurately, acting with awareness, judgment of inner experience, and reactivity to inner experience) predicted pre-1MFU reduction in GAD severity and pre-1MFU reduction in trait perseverative cognitions from MEMI but not SM. MEMI reduced pre-post reactivity to inner experiences (but not other mindfulness domains) significantly more than SM. Only reduced pre-post reactivity significantly mediated stronger efficacy of MEMI over SM on pre-1MFU reductions in GAD severity (indirect effect: β = -2.970 [-5.034, -0.904], p = .008; b path: β = -3.313 [-6.350, -0.276], p = .033; percentage mediated: 30.5%) and trait perseverative cognitions (indirect effect: β = -0.153 [-0.254, -0.044], p = .008; b path: β = -0.145 [-0.260, -0.030], p = .014; percentage mediated: 42.7%). Other trait mindfulness domains were non-significant mediators.

CONCLUSIONS

Reactivity to inner experience might be a mindfulness-based intervention change mechanism and should be targeted to optimize brief MEMIs for GAD.

Introduction to a special issue on the contrast avoidance model

The current paper introduces the special issue on the Contrast Avoidance Model. The Contrast Avoidance Mmodel theorizes that chronic worriers are afraid of a sharp increase in negative emotion and/or sharp reduction in positive emotion (labeled negative emotional contrasts; NECs). They thus use perseverative thought as means to create and sustain negative emotion to prevent NECs if they were to experience negative events. Further, these individuals are uncomfortable with sustained positive emotion because it leaves them vulnerable to NECs. At the same time, worry increases the probability of positive emotional contrasts (PECs), or sharp increases in positive emotion or decreases in negative emotion when things turn out better than expected or positive events are experienced. Therefore, these individuals generate negative emotion via perseverative thought as a way to avoid NECs and increase the likelihood of PECs. The current special issue provides novel research on the model.

The Contrast Avoidance Model: Conclusion and synthesis of new research in the special issue

In this special series, new research on the Contrast Avoidance Model (CAM) was presented, including studies on the role of CAM in the maintenance of chronic worry, the incremental validity of CAM, CAM as a mediator of the association between generalized anxiety disorder (GAD) and other variables, CAM as transdiagnostic, and interpersonal behaviors as a means to avoid negative emotional contrasts (NECs). Furthermore, the role of perseverative thought in relation to positive emotional contrasts (PECs) was explored. Studies indicated that higher worry was positively and negatively reinforced, a factor that is likely to contribute to the maintenance of GAD. Further, research demonstrated that CAM contributed unique variance to understanding GAD above and beyond other variables associated with GAD, such as intolerance of uncertainty and negative problem orientation. Additional research revealed the transdiagnostic nature of contrast avoidance, as well as the association between contrast avoidance and problem-solving deficits. In addition, both worry and rumination increased the likelihood of PECs. Further, data suggested that anxious individuals may use interpersonal strategies to avoid NECs. Finally, savoring positive emotions was found to reduce contrast avoidance, providing a novel intervention strategy to address contrast avoidance in individuals with GAD.

Designing a Perioperative Mind-Body Intervention for Peripheral Vascular Interventions

Background

Peripheral vascular interventions (PVIs) performed under procedural sedation and analgesia (PSA) can be associated with anxiety and poor compliance with patient instructions during surgery. Mind-body interventions (MBIs) such as meditation have demonstrated the potential to decrease perioperative anxiety, though this area is understudied, and no tailored interventions have been developed for the vascular surgical patient population.

Objectives

We aimed to design a perioperative MBI that specifically targeted vascular surgical patients undergoing PVIs under PSA. We sought to perform this in a scientifically rigorous, multi-disciplinary collaborative manner.

Methods

Following the Obesity-Related Behavioral Intervention Trials (ORBIT) model, we designed (Phase 1a) and then refined (Phase 1b) a MBI for patients undergoing PVIs under PSA to decrease perioperative anxiety and sedation and facilitate patient intraoperative compliance. Phase 1a involved a literature review, informal information gathering and synthesis, and drafting a preliminary protocol for a perioperative MBI. Phase 1b involved assembling a multi-disciplinary expert panel of perioperative and mind-body clinicians and researchers to improve the MBI using an iterative, modified Delphi approach.

Results

The modified Delphi process was completed, and a consensus was reached after three iterations. The resulting MBI consisted of two seven-minute preoperative guided meditations on the day of surgery, including diaphragmatic breathing, body scans, and guided imagery emphasizing awareness of the ipsilateral leg where the vascular surgery was performed. A document delineating the integration of the MBI into the operating room workflow was produced, including details regarding the intervention's timing, duration, and modality.

Conclusion

Using a multi-specialty expert panel, we designed a novel MBI in the form of a guided meditation with elements of mindfulness and guided imagery to decrease anxiety and increase intraoperative compliance for patients undergoing PVIs under PSA. A prospective pilot study is being planned to test the program's feasibility.

Psychometric Properties of the Iranian Version of Contrast Avoidance Questionnaires: Could Contrast Avoidance Be a New Transdiagnostic Construct?

The contrast avoidance model (CAM) hypothesizes that individuals with chronic worry recruit worry to create and maintain a negative emotional state to avoid sudden increases in negative emotions. Preliminary evidence using the contrast avoidance questionnaires (CAQs) suggests that there might be a similar mechanism across mood and other anxiety disorders. To continue to assess the CAQs, they should be adapted for other languages and evaluated across multiple symptom domains. The present study aimed to develop the Persian versions of the CAQs and examine the transdiagnostic nature of CAM across two studies. A large Persian-speaking college student sample (Total n = 1438) was used to evaluate the factor structure of the CAQs (Study 1) and the psychometric properties of CAQs (Study 2). Results supported the two-factor structure of the CAQ-W (worry) and CAQ-GE (general emotion). Results showed that CAQ-W was a significant predictor of anxiety-related measures. However, CAQ-GE and IUS-12 significantly predicted depressive and other symptoms over the CAQ-W. Results demonstrated excellent psychometric properties. They indicate that contrast avoidance, measured via CAQ-GE, could be a transdiagnostic construct, and CAQ-W may be more sensitive to anxiety-specific contrast avoidance among Persian speaking and/or Iranian individuals.

Savoring, worry, and positive emotion duration in generalized anxiety disorder: Assessment and interventional experiment

BACKGROUND

Intentional attempts to savor positive emotions may be infrequent in Generalized Anxiety Disorder (GAD) due to avoidance of emotional contrasts. Yet purposeful enjoyment may help reduce worry and increase wellbeing in GAD. We sought to explore 1) the frequency, intensity, and duration of positive emotions from savoring in GAD and 2) its effect on pre-existing worry.

METHOD

The same 139 participants participated in two studies. They first took baseline measures. After, they were explicitly taught about savoring practices. In study 1, all participants were instructed to savor a photograph and video, timing and rating their emotion. Then in study 2, participants underwent a worry induction followed by an interventional experiment. In a savoring condition, participants were instructed to savor a personally-chosen enjoyable video. In a control condition, participants watched an emotionally neutral video.

RESULTS

Participants who met DSM-5 criteria for GAD had significantly lower scores on naturalistic savoring via self-report than those without GAD. Yet when explicitly taught and directed to savor in study 1, there were no differences between those with and without GAD in positive emotion duration and intensity. In study 2, longitudinal linear mixed models demonstrated that savoring after a worry induction significantly decreased worry, decreased anxiety, and increased positive emotions to greater degrees than the control task. These changes did not differ between diagnostic groups. All analyses controlled for depression symptoms.

CONCLUSION

Although persons with GAD tend to savor less in daily life than those without GAD, intentional savoring may decrease worry and increase positive emotion for both groups.

The transdiagnostic use of worry and rumination to avoid negative emotional contrasts following negative events: A momentary assessment study

The contrast avoidance model (CAM) suggests that individuals with generalized anxiety disorder (GAD) are sensitive to a sharp increase in negative and/or decrease in positive affect. They thus worry to increase negative emotion to avoid negative emotional contrasts (NECs). However, no prior naturalistic study has examined reactivity to negative events, or ongoing sensitivity to NECs, or the application of CAM to rumination. We used ecological momentary assessment to examine effects of worry and rumination on negative and positive emotion before and after negative events and intentional use of repetitive thinking to avoid NECs. Individuals with major depressive disorder (MDD) and/or GAD (N = 36) or without psychopathology (N = 27) received 8 prompts/day for 8 days and rated items on negative events, emotions, and repetitive thoughts. Regardless of group, higher worry/rumination before negative events was associated with less increased anxiety and sadness, and less decreased happiness from before to after the events. Participants with MDD/GAD (vs. controls) reported higher ratings on focusing on the negative to avoid NECs and greater vulnerability to NECs when feeling positive. Results support the transdiagnostic ecological validity for CAM extending to rumination and intentional engagement in repetitive thinking to avoid NECs among individuals with MDD/GAD.

Incremental validity of the contrast avoidance model: A comparison with intolerance of uncertainty and negative problem orientation

BACKGROUND

This study examined the incremental validity of the Contrast Avoidance Model (CAM) in predicting generalized anxiety disorder (GAD) symptoms when compared against well-established constructs in the GAD literature: intolerance of uncertainty (IU) and negative problem orientation (NPO).

METHOD

In this study, 185 students (108 of whom endorsed clinical levels of GAD symptoms) completed questionnaires to assess for all constructs. GAD symptoms were regressed on measures of contrast avoidance (CA; Contrast Avoidance-General Emotion and Contrast Avoidance-Worry Questionnaires; Llera & Newman, 2017) tendencies in addition to measures of IU and NPO in separate analyses. Commonality analyses explored the unique versus overlapping contributions of each factor in explaining GAD symptoms.

RESULTS

In all models, CA was a significant predictor after controlling for demographic variables (age, gender, race, and ethnicity) and both IU and NPO. This was also true when excluding CA items referencing worry. All variables contributed unique explanatory power in the prediction of GAD.

CONCLUSION

Results provide evidence of the incremental validity of the CAM as a model of GAD.

Contrast avoidance predicts and mediates the effect of trait worry on problem-solving impairment

This study examined the relationship between the Contrast Avoidance Model (CAM; Newman & Llera, 2011) and impairment in the problem-solving process using an in-vivo laboratory-based problem-solving task. We also explored whether general emotional CA tendencies explained the relationship between trait worry and problem-solving outcomes. In this study, 185 participants (42 of whom met diagnostic criteria for generalized anxiety disorder) engaged in a problem-solving task, and reported outcomes related to ability to generate solutions, confidence in solutions, intention to implement solutions, and state anxiety levels. According to results, higher general emotional CA tendencies predicted significantly more difficulties on most problem-solving outcomes. Further, CA tendencies mediated between trait worry and some, but not all, problem solving outcomes. Overall, CA appears to be linked to problem-solving deficits, and may help to explain some of the association between trait worry and negative problem-solving outcomes.

Contrast avoidance prospectively mediates effects of fear of emotional responding, negative problem orientation, and sensitivity to low perceived control on generalized anxiety disorder symptoms

The Contrast Avoidance Model (CAM; Newman & Llera, 2011) has been well established in the literature on the etiology and maintenance of generalized anxiety disorder (GAD). Research has investigated other factors that may also characterize GAD, such as fear of emotional responding, negative problem orientation (NPO), and negative beliefs about control; however, these have yet to be explored within the context of the CAM regarding maintenance of GAD symptoms. The purpose of this study was to explore the predictive relationship between the above-mentioned factors and GAD symptoms, mediated by contrast avoidance. Participants (N = 99, 49.5% of whom scored in the upper range on GAD symptoms) completed a series of questionnaires across three time points, each one week apart. Results indicated that fear of emotional responding, NPO, and sensitivity to low perceived control predicted CA tendencies a week later. CA tendencies then mediated the relationship between each predictor and GAD symptoms in the following week. Findings suggested that known vulnerabilities for GAD predict coping with distressing internal responses via sustained negative emotionality (such as through chronic worry) as a way to avoid negative emotional contrasts. However, this coping mechanism itself may maintain GAD symptoms over time.

A transdiagnostic evaluation of contrast avoidance across generalized anxiety disorder, major depressive disorder, and social anxiety disorder

BACKGROUND

The contrast avoidance model (CAM) proposes that persons with generalized anxiety disorder (GAD) are sensitive to sharp increases in negative emotion or decreases in positive emotion (i.e., negative emotional contrasts; NEC) and use worry to avoid NEC. Sensitivity to and avoidance of NEC could also be a shared feature of major depressive disorder (MDD) and social anxiety disorder (SAD).

METHODS

In a large college sample (N = 1409), we used receiver operating characteristics analysis to examine the accuracy of a measure of emotional contrast avoidance in detecting probable GAD, MDD, and SAD.

RESULTS

Participants with probable GAD, MDD, and SAD all reported higher levels of contrast avoidance than participants without the disorder (Cohen's d = 1.32, 1.62 and 1.53, respectively). Area under the curve, a measure of predictive accuracy, was 0.81, 0.87, and 0.83 for predicting probable GAD, MDD, and SAD, respectively. A cutoff score of 48.5 optimized predictive accuracy for probable GAD and SAD, and 50.5 optimized accuracy for probable MDD.

CONCLUSION

A measure of emotional contrast avoidance demonstrated excellent ability to predict probable GAD, MDD, and SAD. Sensitivity to and avoidance of NEC appears to be a transdiagnostic feature of these disorders.

Reducing contrast avoidance in GAD by savoring positive emotions: Outcome and mediation in a randomized controlled trial

This secondary analysis of a randomized controlled trial (RCT) examined whether contrast avoidance (CA) in Generalized Anxiety Disorder (GAD) could be reduced through savoring-purposeful engagement with positive emotions. 85 participants were diagnosed with GAD by both questionnaire and clinical interview. They were then randomly assigned to one of two seven-day smartphone-delivered ecological momentary interventions (EMIs). The SkillJoy EMI facilitated in-the-moment practice of savoring positive emotions in participants' daily lives. The active self-monitoring control (ASM) was nearly identical to SkillJoy in ratings, activities, and language, yet omitted specific attention to positive emotion and savoring. CA was assessed by questionnaire at pre-trial and post-trial. Savoring was assessed by questionnaire at pre-trial and fifth-day mid-trial. Longitudinal linear mixed models and simple slope analyses examined CA change between and within conditions. Bias-corrected boot strapping path analysis examined mediation by savoring using individuals' CA slopes extracted from a multilevel model as outcome. Results showed that SkillJoy led to significant reductions in CA, whereas the ASM control did not. The relation between treatment condition and reduction in CA was mediated by increases in savoring from pre- to mid-trial. It may be possible for treatment to meaningfully reduce CA in GAD, specifically through savoring practices.

The naturalistic reinforcement of worry from positive and negative emotional contrasts: Results from a momentary assessment study within social interactions

BACKGROUND

The Contrast Avoidance Model (Newman & Llera, 2011) proposes that worry is reinforced by avoiding a negative contrast and increasing the likelihood of a positive contrast.

OBJECTIVE

To determine if reinforcement of worry occurs naturalistically via contrasts in both negative and positive emotion.

METHOD

Using event-contingent momentary assessment we assessed social interactions, pre-interaction state worry and pre-post interaction positive and negative emotion. Participants with generalized anxiety disorder (GAD; N = 83) completed an online questionnaire after social interactions lasting at least 1 min for 8 days. Three-level multilevel models were conducted.

RESULTS

Higher worry was concurrently associated with increased negative emotion and decreased positive emotion. Regardless of pre-interaction worry level, negative emotion decreased, and positive emotion increased from before to after interactions, suggesting that most interactions were benign or positive. At lower levels of pre-interaction worry, participants experienced increased negative emotion and decreased positive emotion from before to after interactions. At higher levels of pre-interaction worry, participants experienced decreased negative emotion and increased positive emotion from before to after interactions.

CONCLUSION

Among persons with GAD, worrying before social interactions may be both negatively and positively reinforced; furthermore, not worrying before social interactions may be both negatively and positively punished.

A five-factor model of perseverative thought

Like diagnostic status, clinically relevant thought remains overwhelmingly conceptualized in terms of discrete categories (e.g., worry, rumination, obsessions). However, definitions can vary widely. The area of perseverative thought (or clinically relevant thought more broadly) would benefit substantially from a consensus-based, empirically grounded taxonomy similar to the Hierarchical Taxonomy of Psychopathology (Kotov et al., 2017) or the Big Five for personality. This article addresses three major barriers to establishing such a taxonomy: (a) a lack of research explicitly comparing categorical (subtype) versus dimensional models, (b) primary reliance on between-person measures rather than modeling at the level of the thought (within person), and (c) insufficient emphasis on replication and refinement. Participants included an unselected crowdsourced sample (790 observations from 286 participants) and an independent anxious-depressed replication sample (808 observations from 277 participants). Participants made dimensional ratings for three idiographic clinically relevant thoughts on a range of features. Multilevel latent class analysis and multilevel exploratory factor analysis were applied to identify and extract natural patterns of covariation among features at the level of the thought, controlling for person-level tendencies. A consistent five-dimension solution emerged across both samples and reliably outperformed the best-fitting categorical solution in terms of fit, replicability, and explanatory power. Identified dimensions were dyscontrol, self-focus, valence, interpersonal, and uncertainty. Findings support a five-factor latent structure of perseverative thought. Theoretical, empirical, and clinical implications and future directions are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Validation of the Chinese Version of Relaxation Sensitivity Index: A Tool for Predicting Treatment Effect in Mindfulness Interventions

Background: The Relaxation Sensitivity Index (RSI) measures relaxation-related fears developed and validated in western samples. The RSI captures three facets of fear regarding relaxation: physical, cognitive, and social concerns. This study aimed to translate and identify the factor structure of the Chinese version of the RSI. Methods: In a preliminary study, 26 items were generated mainly by translation and modified from the original RSI. In Study 1, factor analysis and internal consistency reliability analysis were conducted on separated half samples of 597 Chinese college students. In Study 2, test-retest reliability, convergent, and predictive criterion validity were examined based on 465 Chinese college students. Results: Fourteen items were selected based on the factor loading and item prevalence in the preliminary study. Factor analysis based on Study 1 identified three factors: Social appealing, Social performance, and Physical concerns. In general, the RSI demonstrated good internal consistency (αs = 0.750-0.860), convergent validity and predictive criterion validity, while the test-retest reliability is relatively low (rs = 0.525-0.685). Notably, less related to the other two factors, Social performance concerns may be a unique factor solely predicting social anxiety (p <0.001), but not relaxation-induced anxiety (p = 0.442). Conclusion: The Chinese version of the RSI possesses a factor structure different from the western population. The robustness of factor structure and test-retest reliability was not as good as expected. Further research is warranted to explore the validity of the RSI in Chinese samples.

Health-related benefits and adverse events associated with yoga classes among participants that are healthy, in poor health, or with chronic diseases

Background

Our previous study demonstrated that 42% of yoga class participants in Japan had chronic diseases requiring medication. This raises the question as to whether those with chronic diseases would benefit from practicing yoga or if they are at higher risk for specific adverse events compared to healthy individuals receiving the same instruction.

Methods

To address these questions, 328 adults who started practicing yoga for the first time were asked to complete the Profile of Mood States (POMS), Perceived Stress Scale (PSS), and Medical Outcomes Study Short Form 8, standard version (SF-8™) and to record any adverse events on the first day of the yoga class and again three months later. The participants consisted of three groups: a healthy (H) group (n = 70), a poor health (PH) group (n = 117), and a chronic disease (CD) group (n = 141). The degree of subjective symptoms was also compared between the pre- and post-intervention period in the PH and CD groups.

Results

Typically, yoga classes were held once a week for 60–90 min. The programs included asanas, pranayamas, meditation, isometric yoga, and sukshma vyayama. In the PH and CD groups, the POMS tension-anxiety and fatigue scores decreased and the vigor score increased significantly after the first class. Furthermore, PSS scores decreased and the SF-8™ scores increased significantly three months later. The degree of subjective symptoms such as easy fatigability, shoulder stiffness, and insomnia also decreased over three months. Individuals in these groups experienced more frequent adverse events than those in the H group. The PH and CD groups also experienced a greater variety of symptoms, including psychological ones, not reported by the H group. Adverse events were not so serious that participants stopped practicing yoga during the class. About 60% of all participants were highly satisfied with participating in yoga classes.

Conclusions

If yoga classes are conducted with attention to possible adverse events, yoga practice in a yoga studio may have beneficial effects for people with functional somatic symptoms and chronic diseases, as well as healthy participants. These benefits include reductions in perceived stress and uncomfortable symptoms as well as improved mood and quality of life.

Development and Initial Validation of the Relaxation Sensitivity Index

Relaxation sensitivity indexes the fear of relaxation-related events. The purpose of this study was to develop and provide initial validation of a self-report measure of relaxation sensitivity, the Relaxation Sensitivity Index (RSI). Three independent samples of undergraduate students (n=300 unselected, n=349 non-clinical, and n=197 clinical analogs with elevated anxiety/depression symptoms) completed self-report measures to examine the factor structure, reliability, and validity of the RSI. Results of exploratory and confirmatory factor analyses supported a three-factor structure (correlated Physical, Cognitive, and Social Concerns). The RSI demonstrated good internal consistency and construct validity as evidenced by expected correlations with measures of anxiety and depression symptoms. The RSI showed good predictive validity in terms of a history of fearful responding to relaxation. RSI scores were significantly higher in the symptomatic compared to non-clinical sample. Results suggest the RSI is a valid and reliable measure that may be useful in clinical and research settings.
