Development and validation of two measures of emotional contrast avoidance: The contrast avoidance questionnaires

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.

An initial test of the contrast avoidance model in bipolar spectrum disorders

The Contrast Avoidance Model suggests that individuals sensitive to negative emotional shifts use prior increases in negative affect to prevent further escalation in response to adverse situations, while the heightened negative affect amplifies positive emotional contrasts when encountering unexpected positive events. Individuals with bipolar spectrum disorders (BSDs), characterized by shifts between (hypo)manic and depressive episodes, may undergo more salient emotional contrasts. Drawing from the Contrast Avoidance Model, the shifts from depression to (hypo)mania can be conceptualized as positive emotional contrasts, potentially heightening the perceived pleasure during (hypo)manic episodes. On the other hand, the shifts from (hypo)manic to depressive episodes can be viewed as negative emotional contrasts, contributing to the challenges associated with depressive states. Despite the intriguing potential of this interplay, the link between the Contrast Avoidance Model and BSDs has never been empirically tested. Our study addressed this gap by examining group differences in contrast avoidance traits between individuals with BSDs, unipolar depression, and healthy controls in a large cohort study (N = 536). Results indicated that individuals with BSDs exhibited significantly higher scores in the total, and Discomfort with Negative Emotional Shifts and Avoidance of Negative Emotional Contrasts/Enhancement of Positive Emotional Contrasts factors, as well as separate item scores on the Contrast Avoidance Questionnaire-General Emotion (CAQ-GE), compared to those with unipolar depression and healthy controls. Although marginal, the BD II subtype demonstrated a stronger inclination to avoid negative emotional contrasts compared to BD I. These findings suggest that contrast avoidance may be a psychological mechanism implicated in BSDs.

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.

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.

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.

Examining the Factor Structure and Incremental Utility of the Contrast Avoidance Questionnaires via Bifactor Analysis

The negative emotional contrast avoidance model posits that pathological worry is maintained by the avoidance of negative emotional shifts. The Contrast Avoidance Questionnaires (CAQ-Worry and CAQ-General Emotion) aim to assess contrast avoidance beliefs and behaviors. Questions remain around the factor structures of the CAQs, whether such structures replicate in nonundergraduate samples, and whether their domain-specific factors are valid for independent use. This study used bifactor analysis in a large community sample (N = 827) to address these gaps in the literature. Results supported bifactor models of both measures. Complementary analyses supported the multidimensionality of the CAQ-Worry, including its strong general factor and independent use of two domain-specific factors, rather than the original three domain-specific factors. The CAQ-General Emotion's general factor was strong, but the merits of the Discomfort domain-specific factor require more exploration, and use of the Avoidance domain-specific factor is discouraged.

Worry and rumination enhance a positive emotional contrast based on the framework of the Contrast Avoidance Model

The Contrast Avoidance Model (CAM) suggests that worry increases negative affect and decreases positive affect. CAM also suggests that in response to a positive event, higher worry enhances the probability of experiencing greater decreased negative affect and increased positive affect (positive emotional contrasts; PECs). Consequently, worrying may be reinforced by repeated PECs. However, no study has tested whether rumination enhances PECs. Also, emotional specificity in these processes has not been considered. Therefore, we tested whether both rumination and worry enhanced PECs related to specific emotions. After resting baseline, participants with pure generalized anxiety disorder (GAD group, n = 91), pure depression symptoms (depression group, n = 91), and non-GAD and non-depressed healthy controls (HCs, n = 93) engaged with randomly assigned induction tasks (either worry, rumination, or relaxation), and then watched an amusement video. Regardless of group, both worry and rumination increased sadness and fear and decreased amusement more than relaxation from baseline. However, worry increased fear more than rumination, and rumination increased sadness more than worry. Although all inductions led to PECs during the video, worry enhanced fear PECs more than rumination, and rumination enhanced sadnessPECs more than worry. The GAD group who worried experienced the most salient PEC of amusement relative to other groups.

Interpersonal contrast avoidance as a mechanism for the maintenance of worry

Despite consistent links between interpersonal problems and worry, mechanisms explaining this relationship remain unknown. The Contrast Avoidance Model (CAM; Newman & Llera, 2011) posits that individuals at risk for chronic worry and generalized anxiety disorder (GAD) fear sudden negative mood shifts, using worry to perpetuate negative moods and avoid these negative emotional contrasts. We propose interpersonal (IP) contrast avoidance (e.g., acting friendly to prevent others from causing mood shifts) as a novel explanation for interpersonal dysfunction in worriers. This study investigated IP contrast avoidance and worry in two samples. A nonclinical sample ranging in GAD symptoms (Study 1; N = 92) reported IP problems at baseline then IP contrast avoidance and worry over eight weeks (637 diaries). As expected, baseline IP problems prospectively predicted worry indirectly through chronic IP contrast avoidance. Affiliative, submissive, cold, and total IP contrast avoidance strategies predicted same-week and lagged next-week worry increases; affiliative, submissive, and total strategies also predicted maintenance of worry over eight weeks in growth models. Lastly, Study 2 showed the relevance of IP contrast avoidance strategies in a treatment-seeking clinical sample (N = 40), correlating with interpersonal problems and worry. Overall, results provide proof-of-concept for extending the CAM to the interpersonal domain.

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.

Correlates of Dampening and Savoring in Generalized Anxiety Disorder

Chronic worry and generalized anxiety disorder (GAD) symptoms are associated with infrequent savoring, and high dampening, of positive emotions. The goal of the present study was to investigate the indirect role of GAD-relevant processes, including intolerance of uncertainty (IU), fear of negative emotional contrasts, and negative beliefs about positive emotion and its regulation, in the relationship between GAD symptom severity and the tendency to engage in dampening and not savor positive emotions. Community participants (N = 233) completed questionnaires online.

In separate models, IU, fear of negative emotional contrasts, and negative beliefs about positive emotion and its regulation fully mediated the relationships between GAD symptom severity and greater dampening and lower savoring. However, controlling for depression, only IU remained a significant mediator. A post hoc latent analysis of the mediators provided support for an underlying construct that may reflect intolerance of uncomfortable states. Intolerance of uncomfortable states was found to significantly mediate the relationship between GAD symptoms and greater dampening and lower savoring. Difficulty withstanding uncertainty may be particularly relevant in understanding why people with elevated GAD symptoms engage in efforts to avoid experiencing positive emotions. Further, the findings suggest that there may be a common factor underlying a variety of GAD-associated constructs reflecting a broad intolerance of uncomfortable inner states. Theoretical and clinical implications are discussed.

Psychotherapeutic treatments for generalized anxiety disorder: cognitive and behavioral therapies, enhancement strategies, and emerging efforts

INTRODUCTION

Generalized anxiety disorder (GAD) is common and disabling. Different versions of cognitive behavioral therapy (CBT) have been tested, but no treatment works for everyone. Therefore, researchers have attempted approaches to enhance CBT.

AREAS COVERED

The current narrative review examines meta-analyses and individual trials of CBT-based treatments for GAD. We focus on CBT and its cognitive and behavioral components as well as efforts to enhance CBT and its dissemination and generalizability. Enhancement efforts included interpersonal and emotional processing therapy, mindfulness-based CBT, emotion regulation therapy, intolerance of uncertainty therapy, the unified protocol, metacognitive therapy, motivational interviewing, and contrast avoidance targeted treatment. Emerging strategies to enhance dissemination have focused on technologically based treatments. Attempts at generalizability have included examination of efficacy within diverse racial and ethnic groups.

EXPERT OPINION

We conclude that CBT is efficacious, and a number of enhancement efforts have shown some promise in improving upon CBT in single trials. However, more research is needed, particularly efforts to determine which enhancements work best for which individuals and what are the mechanisms of change. Furthermore, few technological interventions have been compared to active treatments. Finally, much more attention needs to be paid to ethnic and racial diversity in randomized controlled trials.

Avoidance of negative emotional contrast from worry and rumination: An application of the Contrast Avoidance Model

According to the Contrast Avoidance model (CAM), worry causes increased and sustained negative affect and such negative affect enables avoidance of a future sharp increase in negative emotion. However, only pathological worriers (vs. controls) view worry as a positive coping strategy to avoid a negative emotional contrast (NEC). We examined if rumination, which is another type of repetitive negative thought, would function similarly. Individuals with self-reported symptoms of pure generalized anxiety disorder (GAD; n = 90), pure depression (MDD; n = 85), and non-anxious/non-depressed controls (HC; n = 93) were randomly assigned to conditions where they were asked to worry, ruminate, or relax. Emotional and physiological changes were measured during worry and subsequent exposure to fearful and sad videos. We also assessed participant group differences in preference for worry or rumination as a strategy to cope with negative affect during the negative emotional video exposures. Consistent with CAM, regardless of the group, both worry and rumination enabled avoidance of NEC. Whereas worry led to greater avoidance of a fear contrast, rumination led to greater avoidance of a sadness contrast. On the other hand, relaxation enhanced NEC. Skin conductance also indicated patterns in line with CAM. In the subjectively perceived preference, the GAD group reported a greater preference for worry in coping with a fear contrast than HC. However, such a salient pattern was not found for the MDD group. Treatment implications of these findings are discussed.

Positive beliefs about worry: An evaluation of the Why Worry-II questionnaire in patients with anxiety and mood disorders: Implications for theory and treatment

Positive beliefs about worry are an important factor that has been shown to be associated with the reduction of worry severity with cognitive behavioural therapy. The present study evaluated the psychometric properties of a measure of positive beliefs about worry, the Why Worry Questionnaire II (WW-II; Hebert et al., 2014, 0.1016/j.paid.2013.08.009) with a clinical sample. The present study also compared mean scores on the WW-II in the present clinical sample with scores found in non-clinical samples. Finally, the study compared mean scores on the WW-II between groups with primary diagnoses of generalized anxiety disorder (GAD), major depressive disorder (MDD) and anxiety disorder not otherwise specified (NOS). The confirmatory factor analysis found the five-factor model an adequate to good fit to the data, and the WW-II demonstrated excellent internal consistency within this clinical sample. Additionally, scores on the WW-II in the present sample were significantly higher than scores found by in their non-clinical sample. Finally, no significant mean differences were found between primary diagnoses of GAD, anxiety disorder NOS or MDD. Important theoretical and clinical implications and suggestions for future research are discussed.

Psychometric Properties and Prospective Predictive Utility of the Contrast Avoidance Questionnaires

Abstract. Recent theoretical research posits that a key factor in the development and maintenance of pathological worry is the avoidance of sudden emotional shifts. Recently two self-report instruments were developed to index this phenomenon (Contrast Avoidance Questionnaire – Worry [CAQ-W] and Contrast Avoidance Questionnaire – General Emotion [CAQ-GE]). This work employed a multi-study design to provide an independent evaluation of the latent structure of these measures; additionally, the validity and longitudinal predictive ability of the measures was examined. Findings of the factor analytic work support a two-factor solution for each of the questionnaires. These were defined as the following subscales: CAQ-W: Emotional Contrast; Negative Affect, and for the CAQ-GE: Avoidance; Discomfort. Test-retest reliability of the measure was strong and the identified subscales demonstrated differential predictive ability regarding future worry and depression. Results indicate that subscales related to the experience of negative affect rather than avoidance, display predictive utility of future symptoms. These findings are somewhat discrepant with extant literature on ecological momentary assessment (EMA) assessment of contrast avoidance indicating the need for refinement in the self-report measurement of this construct.

Therapist-guided online metacognitive intervention for excessive worry: a randomized controlled trial with mediation analysis

Previous studies have found an association between excessive worrying and negative beliefs about worry. It is unclear if change in these beliefs mediate worry reduction. This study aimed to examine (1) if a simplified online metacognitive intervention can reduce worry, (2) whether changes in negative beliefs about worry mediate changes in worry severity, and (3) moderated mediation, i.e., if the mediating effect is more pronounced in individuals with a high degree of negative beliefs about worry at baseline. Adult excessive worriers (N = 108) were randomized to 10-weeks of the online metacognitive intervention (MCI) aimed at reducing negative beliefs about worry, or to wait-list (WL). Outcomes, mediation, and moderated mediation were examined via growth curve modelling. Results indicated a significant reduction in the MCI group (d = 1.6). Reductions in negative beliefs about worry and depressive symptoms separately mediated changes in worry severity during the intervention, but in a multivariate test only the former remained significant. Sensitivity analysis indicated that the hypothesized mediation was robust to possible violations of mediator-outcome confounding. The moderated mediation hypothesis was not supported. The results from this randomized trial add to the growing literature suggesting that negative beliefs about worry play a key role in worry-related problems.

Development of an Assessment Tool of Menstrual-Cycle-Related Signs and Symptoms Based on Thai Traditional Medicine Principles for Evaluation of Women's Health

Background

Utilization of Thai traditional medicine (TTM) was considered in menstrual-cycle-related signs and symptoms (MCSs) to evaluate women's health. TTM clinicians diagnosed the MCSs by signs, symptoms, and associated factors of patients including a physical examination to find patterns of imbalance elements and the origin of the disorder to optimize treatment. Thus, the purpose of this study was to develop a new assessment tool, the menstrual-cycle-related signs and symptoms questionnaire (MCSQ) based on TTM principles for evaluation of women's menstrual health.

Methods

The items and components of the MCSQ were adjusted by TTM expert consensus using the Delphi technique. The content validity of the MCSQ was quantified by the content validity index (CVI). MCSQ were examined by construct validity and internal consistency reliability using exploratory factor analysis (EFA) and Cronbach's α coefficient, respectively.

Results

: All 19 experts (100%) responded to the questionnaires in the three rounds of the Delphi technique. The MCSQ showed high content validity of individual items (I-CVI = 0.83-1.00) and high overall content validity of the questionnaire (S-CVI/AVE = 0.98). Overall, 429 of 432 participants completed the questionnaire (99.31%). After factor analysis, the final MCSQ was divided into two sections, which consisted of 49 items. The first had 23 items focusing on the MCSs. And, the second had 14 items of personal and medical data including 12 items of associated factors. Cronbach's α coefficient of the final MCSQ was 0.87, and that of each component was between 0.32 and 0.82.

Conclusions

This study reports a new MCS questionnaire tool, which was developed from TTM knowledge to evaluate women's health. This questionnaire showed an acceptable level of validity and reliability. Thus, it is also expected to be useful in clinical practice and ongoing research on evaluation of women's health.

Worry as a mediator between psychosocial stressors and emotional sequelae: Moderation by contrast avoidance

BACKGROUND

Worry is the core feature of generalized anxiety disorder (GAD), which is prevalent among emerging adults. The contrast avoidance model proposes that individuals with GAD use worry to avoid negative emotional contrasts by maintaining a state of negative affect. Research suggests worry in response to stressors increases anxiety, but more research is needed to examine depression as an outcome and the predictions of contrast avoidance in the context of multiple stressor subtypes. The current study examined whether worry may be associated with increased symptoms of anxiety and depression, regardless of stressors, due to the use of worry as an avoidance strategy, moderating these associations.

METHODS

367 undergraduate college students from a medium-sized, public university completed self-report questionnaires online.

RESULTS

Worry significantly mediated the associations from academic stressors and social stressors to symptoms of anxiety and depression. Contrast avoidance significantly moderated associations between academic stressors and worry as well as worry and anxiety. For those high in contrast avoidance, worry was relatively high regardless of academic stressors; for those low in contrast avoidance, students with fewer academic stressors reported less worry.

LIMITATIONS

The present study relied on self-report. In addition, the cross-sectional design limits the ability to draw conclusions about temporal relations.

CONCLUSIONS

Contrast avoidance elevated worry regardless of academic stressors, and strengthened the association between worry and anxiety but not worry and depression. Individuals who experience high levels of contrast avoidance may benefit from cognitive interventions focusing on reducing beliefs about the perceived benefits of worry.

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

BACKGROUND

The Contrast Avoidance Model postulates that individuals with generalized anxiety disorder (GAD) fear a sharp spike in negative emotion, and thus, prefer to worry to maintain their negative affect rather than being in a more euthymic state, such as relaxation. Relaxation induced anxiety (RIA) is a paradoxical phenomenon wherein people experience a spike in their anxiety during relaxation training. Because these phenomena may be related and may also operate among individuals with major depressive disorder (MDD), we attempted to test whether negative contrast sensitivity was a mediator of GAD or MDD in the prediction of RIA.

METHODS

Individuals with GAD (n = 32), MDD (n = 34), and healthy controls (n = 30) were exposed to a negative emotional contrast by engaging with relaxation practice and then watching a negative emotional video. This was followed by the assessment of their negative contrast sensitivity. After this, participants engaged again with relaxation and RIA was measured. We examined mediation effects of negative contrast on the relationship between diagnostic status and RIA.

RESULTS

Negative contrast sensitivity fully mediated GAD and partially mediated MDD in predicting RIA.

CONCLUSIONS

Our findings support the hypotheses that negative contrast sensitivity is the mediator of both GAD and MDD in predicting RIA. This may have implications for assessment and treatment of GAD and MDD.

"Cold" Cognitive Control and Attentional Symptoms in Anxiety: Perceptions Versus Performance

Clinically significant anxiety is associated with an array of attentional symptoms (e.g., difficulty concentrating; unwanted thought) that are subjectively experienced as severe. However, neuropsychological findings are mixed with respect to the presence of cognitive deficits that can account for these symptoms. Contextualizing predictions from established clinical theories (e.g., Attentional Control Theory) within contemporary, neurobiologically derived models of cognitive control (Dual Mechanisms of Control Theory), the present study investigated the relationship between "cold" proactive and reactive cognitive control, task effort, and subjective attentional symptoms (difficulty concentrating; unwanted thought) in a mixed clinical sample of individuals with generalized anxiety disorder (GAD) and/or obsessive-compulsive disorder (OCD) and a comparison sample of healthy controls. Clinical status moderated the relationship between attentional symptoms (attentional focusing and trait worry) and proactive cognitive control response time. Clinical status also moderated the relationship between trait worry and task effort. Higher trait worry was associated with slower proactive control and lower effort in healthy participants, but faster proactive control in clinical participants. Self-reported attentional focusing showed differential validity vis-à-vis proactive control response time in clinical versus healthy participants. Post-hoc conditional effects analysis suggested more accurate self-appraisals in healthy controls, but was not significant after correction for multiple comparisons. Preliminary evidence suggested that differences in task effort in anxious versus healthy adults may relate to subjective attentional symptoms in GAD and OCD.

The impact of uncontrollability beliefs and thought-related distress on ecological momentary interventions for generalized anxiety disorder: A moderated mediation model

This study was a secondary analysis of LaFreniere and Newman (2016), a randomized controlled trial comparing two ecological momentary interventions (EMIs) for generalized anxiety disorder (GAD): The worry outcome journal (WOJ) and thought log (TL). We predicted that higher thought-related distress would be a mediator by which higher uncontrollability beliefs (UB) would hinder the efficacy of the WOJ, but not the TL. Fifty-one undergraduates who met GAD criteria underwent one of the EMIs for 10 days. WOJ users tracked worries, associated distress, interference, expected outcome probabilities, and whether their worries came true four times/day. TL users tracked general thoughts, associated distress, and interference four times/day. Bootstrapping path analysis was used to analyze moderated mediation models. Higher UB predicted higher thought-related distress for both EMIs. Higher UB also predicted reduced efficacy of the WOJ at post-trial and of both EMIs at 30-day follow-up. However, for WOJ users, when higher initial UB levels predicted higher thought-related distress early in treatment, participants reported greater levels of worry at post-trial and follow-up. In contrast, UB's effect on the TL group at post-trial and follow-up was not mediated by early distress. Thought-related distress appears to be a mechanism by which UB impedes the WOJ intervention.

Probabilistic Learning by Positive and Negative Reinforcement in Generalized Anxiety Disorder

This experiment examined learning tendencies in generalized anxiety disorder (GAD) using reinforcement feedback for probabilistic outcomes. One hundred sixty-six GAD and 105 non-GAD participants were randomized to a computerized probabilistic learning task that used either negative or positive reinforcement. Participants chose between stimuli with specific probabilities of reinforcement to learn which of each pair had the highest probability. Reinforced choices either removed an angry face (negative reinforcement) or made a happy face appear (positive reinforcement). Results showed that those with GAD learned the correct probabilistic choices at a slower rate over time and to a lesser degree than control participants regardless of reinforcement type. Estimations of the likelihood of receiving a good outcome posttask were also more inaccurate for those with GAD, especially when true likelihoods were high. Furthermore, compared with control participants, those with GAD reported lower perceived reinforcement sensitivity, higher behavioral inhibition sensitivity, and higher undesirable feelings toward probabilistic learning.

Enhanced cognitive control over task-irrelevant emotional distractors in generalized anxiety disorder versus obsessive-compulsive disorder

Generalized anxiety disorder (GAD) is defined in part by excessive and uncontrollable worry. However, little is known about cognitive control abilities in adults with GAD. The present study examined cognitive control over negative and neutral material in a mixed clinical sample of adults with GAD and/or obsessive-compulsive disorder and a comparison healthy control sample. Participants completed a novel emotional variant of the AX-CPT (eAX-CPT) to index proactive and reactive cognitive control in the presence of negative and neutral distractor stimuli. Participants with GAD demonstrated enhanced cognitive control specifically over negative emotional distractors, relative to neutral distractors (within-subjects) and relative to OCD and controls (between-subjects). Findings were specific to GAD versus trait worry; however, higher trait worry predicted better cognitive control in GAD only. These findings are inconsistent with deficit-based cognitive models of GAD and may be better accounted for by models that conceptualize worry as an intentional (albeit maladaptive) cognitive control or emotion regulation strategy that is actively maintained by individuals with GAD in order to avoid engaging with more distressing emotional information.

The Effects of Worry in Daily Life: An Ecological Momentary Assessment Study Supporting the Tenets of the Contrast Avoidance Model

The contrast avoidance model (CAM) suggests that worry increases and sustains negative emotion to prevent a negative emotional contrast (sharp upward shift in negative emotion) and increase the probability of a positive contrast (shift toward positive emotion). In Study 1, we experimentally validated momentary assessment items (N = 25). In Study 2, participants with generalized anxiety disorder (N = 31) and controls (N = 37) were prompted once per hour regarding their worry, thought valence, and arousal 10 times a day for 8 days. Higher worry duration, negative thought valence, and uncontrollable train of thoughts predicted feeling more keyed up concurrently and sustained anxious activation 1 hr later. More worry, feeling keyed up, and uncontrollable train of thoughts predicted lower likelihood of a negative emotional contrast in thought valence and higher likelihood of a positive emotional contrast in thought valence 1 hr later. Findings support the prospective ecological validity of CAM. Our findings suggest that naturalistic worry reduces the likelihood of a sharp increase in negative affect and does so by increasing and sustaining anxious activation.
