There is emerging interest in understanding positive affect dysfunction in relation to anxiety, including worry. This set of two studies examined the association between the inhibition of affect expression (general affect expressivity in Study 1, positive affect expressivity in Study 2) and worry, with a particular interest in the moderating role of proneness to experience positive affect. Subjects were US-residing adults (Study 1 N = 502, Study 2 N = 250) who were recruited through a crowdsourcing website and completed self-report measures of study variables. Moderated regression was used to examine study predictions that affect expression would negatively correlate with worry when coupled with diminished positive affect. Proneness toward negative affect was included as a covariate within multivariate analyses. An interactive effect between affect expressivity and positive affect was supported in Study 2 (positive affect expressivity) but not Study 1 (general affect expressivity) in relation to worry. A diminished tendency to express positive affect was associated with greater worry when coupled with less positive affect. Study results and future directions are discussed in terms of the potential emotion-regulatory functions of positive affect expressivity as it relates to worry.

The present series of studies aimed to develop and provide initial validation of the Ease of Imagery Questionnaire (EIQ)—a measure assessing ease of imaging different positive and negative imagery content reflective of valence and engaging or disengaging in adverse situations. Five studies were conducted to collectively examine the questionnaire’s factor structure and concurrent validity. Study 1 ( N = 336) and Study 2 ( N = 207) informed the development of 16 items of the EIQ, with a four-factor structure supported in Studies 3 ( N = 219), 4 ( N = 135), and 5 ( N = 184) using confirmatory factor analysis. Study 3 also supported concurrent validity with significant bivariate correlations ( p < .05) with the similar Sport Imagery Ability Questionnaire subscales, while studies 4 and 5 demonstrated criterion validity in the EIQ’s prediction of challenge and threat appraisal tendencies, perceived stress, stress mindset, and anxiety and depressive symptoms. Overall, the EIQ demonstrates a replicable four-factor structure and appears to assess ability to image content associated with positive and negative emotions as well as demanding stress-evoking situations.

Emotion suppression may be linked to poor health outcomes through elevated stress-related physiology. The current meta-analyses investigate the magnitude of the association between suppression and physiological responses to active psychological stress tasks administered in the laboratory. Relevant articles were identified through Medline, PsychINFO, PubMed, and ProQuest. Studies were eligible if they (a) used a sample of healthy, human subjects; (b) assessed physiology during a resting baseline and active psychological stress task; and (c) measured self-report or experimentally manipulated suppression. Twenty-four studies were identified and grouped within two separate random effects meta-analyses based on study methodology, namely, manipulated suppression (k = 12) and/or self-report (k = 14). Experimentally manipulated suppression was associated with greater physiological stress reactivity compared to controls (Hg = 0.20, 95% CI [0.08, 0.33]), primarily driven by cardiac, hemodynamic, and neuroendocrine parameters. Self-report trait suppression was not associated with overall physiological stress reactivity but was associated with greater neuroendocrine reactivity (r = 0.08, 95% CI [0.01, 0.14]). Significant moderator variables were identified (i.e., type/duration of stress task, nature of control instructions, type of physiology, and gender). This review suggests that suppression may exacerbate stress-induced physiological arousal; however, this may differ based upon the chosen methodological assessment of suppression.

The metacognitive model of generalized anxiety disorder (GAD) considers Type II worry, which represents one’s tendency to negatively appraise worry, as a defining feature of GAD, and negative metacognitive beliefs are central to eliciting Type II worry during worry episodes. Extant research has found that individuals experiencing GAD report elevated Type II worry, and that negative metacognitive beliefs correlate with Type II worry. However, because of how Type II worry was assessed in existing studies, it remains unclear if negative metacognitive beliefs relate to state Type II worry specifically during a worry episode. This study sought to fill that gap in the existing literature among a sample of individuals experiencing elevated GAD symptom severity ( N = 106). Participants completed an assessment of GAD symptom severity and metacognitive beliefs, while later attending an in-person study session where they completed a worry induction and state Type II worry, as conceptualized as the strength of negative appraisals of worry, which was then assessed. Metacognitive beliefs generally positively correlated with state Type II worry, with negative metacognitive beliefs being the only metacognitive belief domain that correlated with state Type II worry in multivariate analyses. Implications for how these results support the metacognitive model of GAD and treatment implications are discussed.

The issue of race within the context of psychological assessment is important, but often overlooked. Many self-report measures of psychopathology have been developed and validated using primarily White samples. Research regarding the Penn State Worry Questionnaire (PSWQ) and race has produced mixed results, which in turn may present challenges when comparing scores across racial groups. The current article sought to investigate the measurement invariance of the PSWQ and PSWQ-A (an abbreviated version) across four racial groups (White, Black, Asian, and Hispanic) in a sample of 2,489 undergraduate students. Confirmatory factor analysis of a one-factor structure illustrated poor fit across all racial groups for the full-length PSWQ. Two-factor and one-factor with method effects models of the full-length PSWQ each improved on the previous model fit, although the one-factor method effects model was limited by nonsalient factor loadings. Additionally, a separate confirmatory factor analysis indicated good fit for the PSWQ-A. Further analysis of the PSWQ-A suggested measurement invariance across all racial groups, as well as configural, metric, and scalar invariance. These findings advance the literature on the relationship between worry and race, suggesting that direct comparisons on the PSWQ-A between racial groups is appropriate.

The Multidimensional Cognitive Attentional Syndrome Scale (MCASS) was developed to assess the seven maladaptive forms of self-regulation that make up the cognitive attentional syndrome (CAS). Both theory and empirical evidence highlight important distinctions among the seven forms of self-regulation underlying the CAS. The primary purpose of the present study was to determine whether the MCASS item scores are sufficiently multidimensional to warrant the use of subscale scores. A secondary aim was to examine the incremental utility of the MCASS domain-specific factors. A battery of self-report measures was administered to adults recruited through a crowd-sourcing website (N = 359). Bifactor analysis was used to examine the multidimensionality of MCASS item scores. This analytic approach allowed for the quantification of variance captured by each domain-specific item score independent of the general factor. Results from the bifactor analysis suggest that the MCASS is a multidimensional measure, consisting of a strong general factor and domain-specific factors that are sufficiently distinct. Additionally, the majority of domain-specific factors provided incremental utility in predicting two criterion variables (i.e., general distress, happiness emotion goals) after accounting for the general factor. Taken together, results support continued use of the MCASS total scale and subscale scores and suggest that researchers may want to consider using a bifactor model when examining structural models that include the MCASS.

Metacognitive beliefs have emerged as important to health anxiety, particularly beliefs that health-related thoughts are uncontrollable. Preliminary research examining generalized worry indicates uncontrollability beliefs relate more strongly to anxiety among U.S.-based self-identifying White relative to Black college students. The present study sought to extend that line of research by examining if metacognitive beliefs about the uncontrollability of health-related thoughts differentially relate to health anxiety among self-identifying non-Latinx Black (n = 123), Latinx (n = 104), and non-Latinx White (n = 80) U.S.-based primary care patients. As predicted, although positive associations were seen across all three groups, beliefs that health-related thoughts are uncontrollable more strongly related to health anxiety among White patients compared to both Black and Latinx patients. Those differential relations held in multivariate analyses while statistically controlling for positive depression screening status, generalized anxiety symptom severity, and medical morbidity. Although the effect size surrounding the differential relations was small in magnitude, the present results further support the notion that metacognitive beliefs about uncontrollability relate less strongly to anxiety among U.S.-based ethnoracial minorities compared to White individuals. Potential reasons for the differential relations are discussed, along with additional areas for future research.
