RESUMEN

The purpose of the present investigation was to develop and test a measure of negative emotional reactivity to racial/ethnic minoritized stress. In Study 1, we developed item content for a measure of negative emotional reactivity to racial/ethnic minoritized stress. We then evaluated item performance and produced a refined 15-item scale among a large sample of racial/ethnic minority adults (N = 1,343). Results supported a unidimensional construct and high levels of internal consistency. The factor structure and internal consistency were replicated and extended to a sample of Latinx persons who smoke (N = 338) in Study 2. There was evidence of convergent validity of the Emotional Reactivity to Minoritized Stress (ERMS) total score in terms of theoretically consistent and statistically significant relations with indices of mental health problems, social determinants of health, and substance use processes. There was also evidence that the ERMS demonstrated divergent validity in that it was negatively associated with psychological well-being, health literacy, subjective social status in Study 1, and positive abstinence expectancies in Study 2. Overall, the present study establishes the reliability and validity of measuring individual differences in negative emotional reactivity to racial/ethnic minority stress with the ERMS and that such responsivity is associated with behavioral health problems.

RESUMEN

Fear of missing out (FoMO) is a prevalent phenomenon associated with a range of mental health symptoms, such as depression and anxiety. To our knowledge, the question of whether FoMO can be explained by other well-known mechanistic variables-namely, loneliness, rumination, and anxiety sensitivity (AS) - has not been previously evaluated. The current study investigated the predictive power of loneliness, rumination, and AS for explaining variance in FoMO within two independent samples of undergraduate students at a large Northeastern university. Participants completed an online battery of questionnaires. In Study 1, it was found that loneliness and rumination offered significant prediction of FoMO when AS was not considered in the model; however, when these three predictors were considered together, only AS offered significant, non-redundant prediction. Study 2 revealed that both rumination and AS offered significant prediction of FoMO, with AS offering stronger unique prediction. Such findings provide a new frame for understanding the nature of the relatively new concept of FoMO, and in particular, suggest that it may be important to consider AS and rumination in future studies.

RESUMEN

The threat of climate change is associated with both profound health consequences and failures by many individuals to take preventive actions. Behavioral science research on health behavior engagement may serve as a lens through which to better understand attitudes associated with the threat of climate change. This study was designed to examine individual differences in attitudinal responses to climate change, understanding the degree to which these responses can be predicted by both political beliefs and more readily modified psychological factors commonly associated with health behavior engagement: locus of control, anxiety sensitivity, delay discounting, and intolerance of uncertainty. Participants (N = 234) were US adults (62% male; 57% Non-Hispanic White; 44% Democrat) who completed an online survey. Stepwise multiple linear regressions examined which variables provided non-redundant prediction in models of climate change beliefs and concerns. In addition to providing support for the role of political affiliation and related ideology in climate change views (9-23% variance), this study underscores the importance of a behavioral health frame in understanding climate change concerns and beliefs. Known risk factors for negative health behaviors - prominently, locus of control, anxiety sensitivity, and delay discounting - contributed strongly to the understanding of these views, accounting for 4-28% of variance. Our findings encourage greater attention to health behavior-related constructs for understanding attitudes relevant to climate change action.

RESUMEN

BACKGROUND: Exposure-based therapy is an effective first-line treatment for anxiety-, obsessive-compulsive, and trauma- and stressor-related disorders; however, many patients do not improve, resulting in prolonged suffering and poorly used resources. Basic research on fear extinction may inform the development of a biomarker for the selection of exposure-based therapy. Growing evidence links orexin system activity to deficits in fear extinction and we have demonstrated that reactivity to an inhaled carbon dioxide (CO2) challenge-a safe, affordable, and easy-to-implement procedure-can serve as a proxy for orexin system activity and predicts fear extinction deficits in rodents. Building upon this basic research, the goal for the proposed study is to validate CO2 reactivity as a biomarker of exposure-based therapy non-response. METHODS: We will assess CO2 reactivity in 600 adults meeting criteria for one or more fear- or anxiety-related disorders prior to providing open exposure-based therapy. By incorporating CO2 reactivity into a multivariate model predicting treatment non-response that also includes reactivity to hyperventilation as well as a number of related predictor variables, we will establish the mechanistic specificity and the additive predictive utility of the potential CO2 reactivity biomarker. By developing models independently within two study sites (University of Texas at Austin and Boston University) and predicting the other site's data, we will validate that the results are likely to generalize to future clinical samples. DISCUSSION: Representing a necessary stage in translating basic research, this investigation addresses an important public health issue by testing an accessible clinical assessment strategy that may lead to a more effective treatment selection (personalized medicine) for patients with anxiety- and fear-related disorders, and enhanced understanding of the mechanisms governing exposure-based therapy. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05467683 (20/07/2022).

RESUMEN

ABSTRACT: There has been a widespread increase in affective disorders after the emergence of the COVID-19 pandemic. In the current study, we investigated the effects of exposure to and perceived accuracy of news media and demographic characteristics on anxiety and depressive symptoms. We conducted an online survey of US adults (N = 480) using hierarchical linear regression models to understand the predictive roles of duration and frequency of news media exposure, as well as the perceived accuracy of COVID-19 portrayal by the news media, on anxiety and depression. Increased exposure duration predicted greater anxiety, and decreased frequency of exposure and perceived overreaction in the news media coverage of COVID-19 were linked to greater anxiety and depression. Perceived accuracy moderated the relationship of exposure frequency to both affective outcomes. Accordingly, our data support the importance of adequate levels of accurate and trusted information to help mitigate the overall mental health burden of the pandemic.

RESUMEN

Given recent declines in US vaccination rates and the emergence of COVID-19 vaccines, identifying sociodemographic influencers of vaccine willingness holds importance for developing effective public health campaigns aimed at enhancing nationwide COVID-19 vaccine acceptance. The present study utilized a hierarchical binary logistic regression model to assess demographic variables (age, gender, race/ethnicity, pre-existing medical conditions), political party membership, religious affiliation, level of religiosity, and fear of COVID-19 as predictors of COVID-19 vaccine acceptance ('Yes', would receive a vaccine or 'No', would not receive a vaccine) in a national sample of US adults (N = 249). Participants were recruited from Amazon's Mechanical Turk (MTurk) and completed several online questionnaires pertaining to mental health, health behaviors, and responses to the COVID-19 pandemic. Both Democratic party membership and decreased level of religiosity predicted acceptance of a COVID-19 vaccine. This investigation supports political party membership and religiosity as influencers of COVID-19 vaccine willingness and suggests that these variables could represent potential targets for public health interventions aimed at increasing vaccine adoption.

RESUMEN

In this study we provide information on e-cigarette use characteristics in relation to racial and ethnic characteristics in a sample of 535 adult e-cigarette users. We also evaluated how anxiety sensitivity (AS; fear of anxiety) interacted with race/ethnicity to predict vaping outcomes. We found an association between greater AS and higher e-cigarette dependence for White, but not Black, participants. A similar trend was observed for level of risk perception. Also, Hispanic status was associated with higher perception of e-cigarette benefits. Overall, the present study contributes to the understanding of factors linked to e-cigarette use.

RESUMEN

Given the varied emotional and behavioral responses to the COVID-19 pandemic across the United States, further attention to the personal and societal influences on such responses is necessary. We investigated the predictive influence of personal political affiliation and the congruity of personal and governor political affiliation on COVID-19 emotional and behavioral responses, with specific attention to the influence of intolerance of uncertainty (IU) on emotional response. These factors were assessed in two studies of adults in the United States (N = 480, N = 272). We utilized a series of hierarchical linear and logistic regressions to assess predictors of 4 outcomes: (1) trust in governor's response to the pandemic, (2) COVID-19 related worry, and the (3) usage and (4) perceived efficacy of protective health behaviors (e.g., wearing a mask). Across these studies, we found that IU predicted increased COVID-19 related worry. Further, age and personal political affiliation, but not concordance with governor affiliation, predicted COVID-19 behavioral responses. These findings are discussed in relation to the potential importance of linking health messaging to personal characteristics.

RESUMEN

INTRODUCTION: Poor sleep is prevalent among individuals with social anxiety disorder (SAD) and may negatively affect exposure therapy outcomes. Poor sleep may impair memory and learning, and thus compromise fear extinction learning thought to take place in exposure therapy. We examined poor sleep as a predictor of exposure therapy outcomes for SAD and the moderating role of d-cycloserine (DCS) on this relationship. METHODS: Participants were 152 individuals with a primary diagnosis of SAD. As part of a randomized clinical trial evaluating the efficacy of DCS for enhancing the effects of exposure therapy, they completed self-report baseline measure of sleep quality, and self-report sleep diaries assessing sleep duration (total sleep time [TST]) and sleep quality the nights before and after treatment sessions. RESULTS: Poorer baseline sleep quality was significantly associated with slower improvement over time and worse symptom outcomes at the end of treatment and follow-up after controlling for baseline symptoms of depression and social anxiety. Greater TST the night before treatment predicted lower SAD symptoms at the next session, after controlling for symptoms at the previous session. There was no relation between prior or subsequent night sleep quality on symptoms at the next session. No associations were moderated by DCS. CONCLUSIONS: We replicated and extended findings indicating that poor sleep quality is associated with poorer exposure therapy outcomes for SAD. Assessing for sleep difficulties before treatment initiation and incorporating sleep interventions into treatment may enhance exposure therapy outcomes for SAD.

RESUMEN

High distress intolerance (DI: often assessed as anxiety sensitivity) and low working memory capacity (WMC) have each been identified as risk factors for negative health behaviors. To our knowledge, these risk factors have only been studied independently. The current study investigated both the independent and interactive effects of DI and WMC in predicting health-related goal attainment in 118 undergraduates who self-selected a health-related goal. Participants received one of three interventions: values clarification, action planning, or a combination of the two. Across these interventions, we found that DI was at the point of significance (and reflected a small effect size) for predicting goal attainment, whereas WMC was not. Further, we found that when entered into the stepwise regression model together, the interaction of WMC and DI significantly predicted goal success one week later. Specifically, for individuals scoring one standard deviation below the mean in WMC, having worse DI significantly predicted worse goal attainment one week later. We believe this study represents the first published finding of the moderation of the predictive influence of DI by WMC, and underscores the importance of evaluating how risk factors that are typically examined independently operate together.

RESUMEN

Preliminary data suggest that cigarette smokers could have an increased mortality risk from the novel coronavirus (SARS-CoV-2), and that certain factors (e.g., increased age, medical comorbidities) can also increase risk of poor coronavirus disease (COVID-19) outcomes. Between April 30th, 2020 and May 28th, 2020, we evaluated self-reported changes in recent smoking patterns and motivation to quit smoking among current daily cigarette smokers (N = 103) on Amazon Mechanical Turk. We also assessed the relationship of these outcomes to age, medical comorbidity status, and fear of COVID-19. Most participants (68.9%) reported smoking less frequently than usual in the last 28 days. Among daily smokers, increased fear of COVID-19 predicted increased motivation to quit smoking and actual smoking reductions (ps < .05). Endorsement of one or more medical comorbidities, but not increased age, predicted increased motivation to quit smoking (p < .05). These data suggest the potentially greater relevance of psychological factors (e.g., fear of COVID-19) over external risk factors (e.g., medical comorbidity, increased age) on motivation to quit smoking and actual reductions in smoking patterns, and may reflect that the pandemic is a suitable time for offering smoking cessation intervention.

RESUMEN

Electronic cigarette (e-cigarette) use has risen exponentially since its initial introduction. The widespread and growing use of these novel products has prompted increased research to evaluate use from a nuanced perspective that considers patterns and antecedents of use. Specifically, research has identified sociodemographic characteristics related to varying levels of e-cigarette use frequency. Yet, limited research has investigated broad-based psychological factors related to frequent and infrequent e-cigarette use. The current study sought to address this clinically relevant research gap within a cross sectional design. Several affective vulnerability states were evaluated, including anxiety sensitivity, anxious arousal, general distress, and anhedonia across 566 (51.1% female, Mage = 35.3 years, SD = 10.1) non-daily and daily past month, adult e-cigarette users. Results demonstrated that in comparison to non-daily e-cigarette users, daily users evinced significantly higher levels of anxiety sensitivity, anxiety sensitivity cognitive concerns, anxiety sensitivity social concerns, anxiety sensitivity physical concerns, anxious arousal, and general distress. No significant differences were found for anhedonic depression. Overall, the current study provides initial and novel empirical evidence that certain affective vulnerability constructs related to anxiety may be more strongly endorsed by daily e-cigarette users. Importantly, this work adds to evolving, but underdeveloped, e-cigarette models by highlighting the need to consider anxiety-related constructs when evaluating e-cigarette use patterns and behavior.

RESUMEN

BACKGROUND: Cognitive behavioral therapy (CBT) is an efficacious intervention for generalized anxiety disorder (GAD). Digital CBT may provide a scalable means of delivering CBT at a population level. We investigated the efficacy of a novel digital CBT program in those with GAD for outcomes of anxiety, worry, depressive symptoms, sleep difficulty, wellbeing, and participant-specific quality of life. METHODS: This online, two-arm parallel-group superiority randomized controlled trial compared digital CBT with waitlist control in 256 participants with moderate-to-severe symptoms of GAD. Digital CBT (Daylight), was delivered using participants' own smartphones. Online assessments took place at baseline (Week 0; immediately preceding randomization), mid-intervention (Week 3; from randomization), post-intervention (Week 6; primary endpoint), and follow-up (Week 10). RESULTS: Overall, 256 participants were randomized and intention-to-treat analysis found Daylight reduced symptoms of anxiety compared with waitlist control at post-intervention, reflecting a large effect size (adjusted difference [95% CI]: 3.22 [2.14, 4.31], d = 1.08). Significant improvements were found for measures of worry; depressive symptoms, sleep difficulty, wellbeing, and participant-specific quality of life. CONCLUSION: Digital CBT (Daylight) appears to be safe and efficacious for symptoms of anxiety, worry, and further measures of mental health compared with waitlist control in individuals with GAD.

RESUMEN

Exercise is an efficacious intervention for mental and physical health, but few studies have identified the additive benefits of exercise prescriptions for those undergoing empirically supported psychosocial treatment. Behavioral activation (BA) involves completing activities to improve mood, an ideal format for exercise augmentation. The purpose of this study was to examine the credibility and exploratory effect size estimates of augmenting BA with exercise. Thirty-one sedentary, depressed patients were randomized to receive nine sessions of BA+exercise or BA+stretching over 12 weeks. Monthly assessments of depression, quality of life, distress intolerance (DI), perceived stress, and exercise were conducted. Results demonstrated strong credibility and completion rates of BA+exercise, comparable to other PA interventions. Randomization did not contribute to differential exercise between conditions; all participants engaged in more exercise over time. Similarly, all participants significantly improved on all outcomes over time. Condition differences emerged for DI and perceived stress; the exercise condition evidenced greater improvements over time. Participants who engaged in more exercise also evidenced greater and faster declines in depression. BA may be a useful strategy for improving depression and increasing exercise. Additional explicit exercise prescriptions may not be necessary to improve depression but may be helpful for DI and stress.

RESUMEN

Refining the mechanisms behind illicit drug use is an important factor for improving the quality of clinical care. Research in alcohol, marijuana, and nicotine use disorders have linked coping motives (e.g. using substances to ameliorate negative emotional states) to problematic substance use. We evaluated the link between emotion regulation difficulties (as assessed via the difficulties in emotion regulation scale [DERS]) and motives for drug use (as assessed via the Drug Use Motives Questionnaire) among individuals (n = 68) with opioid use disorders who were in methadone maintenance treatment. We found that the DERS total score was significantly associated with coping motives for use. Nonacceptance of emotional responses was the only DERS domain that offered nonredundant prediction of coping motives. These findings highlight the relevance of specific emotion regulation deficits in motives for illicit drug use among individuals with opioid use disorders and may help inform targeted cognitive-behavioral treatments in this population.

RESUMEN

Initial evidence suggests that experiential avoidance (EA) mediates the relation between anxiety sensitivity (AS) and depression. We examined the AS-EA-depression pathway, examining both concurrent, and prospective (cross-lag), mediation models. Utilizing data from a study that examined the effects of exercise on AS (N = 60), we modeled depressive symptoms, EA, and AS over four time points. Time-varying predictors were disaggregated into between-subjects (each person's mean level of the predictor) and within-subjects change (each person's deviations, at each time point, from their mean level on the predictor) components. Tests of the concurrent relations were partially consistent with predictions, with mean EA levels, but not within-subjects changes in EA, partially mediating the relation between AS and depression symptom severity. However, the prospective, cross-lag mediation model, in which AS predicted future EA controlling for previous EA, and EA predicted future depression, controlling for previous depression, yielded no significant effects. These results suggest that observed between-subjects mediation findings, found here and in previous studies, may not replicate using more stringent, quasi-causal, cross-lag mediation analyses. These results highlight the importance of estimating causal pathways in mediation analyses. Clinical implications and directions for future research are discussed.

RESUMEN

The present study aimed to replicate the finding that younger age predicts higher pre quit-day attrition. Our second aim was to explain this relation by examining empirically and theoretically informed age-related risk factors for low smoking cessation treatment engagement. 136 participants (Mage = 44.2 years, SD = 11.3 years; age = 22-64 years) were randomized to 15-weeks of either 1) an exercise intervention (n = 72) or 2) a wellness education control condition (n = 64). First, a logistic regression analysis was employed to test whether younger adults were more likely than older adults to drop prior to quit date. Next, we assessed whether smoking related health concerns, social expectancies, and/or perceived severity of craving affected the strength of the relation between age and attrition, by adding these three variables to the logistic regression along with age. The logistic regression model indicated that younger age and treatment condition were significantly related to the odds of dropping from treatment prior to the scheduled quit date. Further, health concerns, social expectancies, and/or perceived severity of cravings did not account for the effect of age on pre quit-day attrition. These findings highlight the importance of identifying empirically and theoretically informed variables associated with the pre quit-day attrition problem of young smokers.

RESUMEN

Evidence exists for a negative influence of exercise/weight-loss television on explicit attitudes towards exercise. However, it is unclear if this is specific to viewing intense exercise or the overweight/obese status of the viewed exercisers. Additionally, exposure to exercise cues can induce people to eat more, reflecting compensatory eating in response to exercise cues rather than actual exercise. In this study, we examined the relative influence of viewing overweight/obese versus normal weight exercisers on eating (calories consumed) and attitudes towards exercise. 102 college students were randomized to view: 1) overweight/obese individuals engaging in vigorous exercise; 2) normal weight individuals engaging in vigorous exercise; or 3) no-exercise video with participants of various weight statuses (control condition). Participants subsequently completed a taste test assessing calories consumed; a computerized, implicit attitudes-towards-exercise task; and an explicit attitudes-towards-exercise questionnaire. Participants with higher BMIs and those viewing normal weight exercisers (vs. overweight/obese exercisers) ate significantly more. No significant effects were found for the interaction between BMI and video or for explicit or implicit attitudes towards exercise. This study extends findings of the impact of viewing vigorous exercise to eating behaviors. If replicated under naturalistic conditions, findings have implications for health promotion initiatives and television programming impacting overeating.

RESUMEN

BACKGROUND: Animal models and human studies have identified the potential of modafinil as a cognitive enhancing agent, independent of its effects on promoting wakefulness in sleep-deprived samples. Given that single-dose applications of other putative memory enhancers (eg, D-cycloserine, yohimbine, and methylene blue) have shown success in enhancing clinical outcomes for anxiety-related disorders, we conducted a meta-analytic review examining the potential for single-dose effects for modafinil on cognitive functioning in non-sleep-deprived adults. METHODS: A total of 19 placebo-controlled trials that examined the effects of single-dose modafinil versus placebo on the cognitive domains of attention, executive functioning, memory, or processing speed were identified, allowing for the calculation of 67 cognitive domain-specific effect sizes. RESULTS: The overall positive effect of modafinil over placebo across all cognitive domains was small and significant (g = 0.10; 95% confidence interval, 0.05-0.15; P < 0.001). No significant differences between cognitive domains were found. Likewise, no significant moderation was found for modafinil dose (100 mg vs 200 mg) or for the populations studied (psychiatric vs nonpsychiatric). CONCLUSIONS: In conclusion, the available evidence indicates only limited potential for modafinil to act as a cognitive enhancer outside sleep-deprived populations.

RESUMEN

BACKGROUND AND OBJECTIVES: Electronic cigarettes (e-cigarettes) are recognized as a prevalent form of substance use among adults in the United States. The rise in e-cigarette use has motivated research to identify subgroups of the population that may be particularly vulnerable to e-cigarette use and its associated harm. Individuals with elevated psychological vulnerability are one such group more at risk for being a lifetime or current e-cigarette user. Yet, little is known about how factors of psychological vulnerability relate to perceptions of e-cigarette use within the context of e-cigarette quit attempts. The current study evaluated the differential relations of anxiety sensitivity (AS), a core affective vulnerability factor, on several relevant e-cigarette processes across those with and without a previous attempt to quit using e-cigarettes. METHODS: Our sample consisted of 547 current e-cigarette users (51% female, Mage = 35.38 years, SD = 10.1). RESULTS: Results indicated that AS significantly related to greater perceived risks, benefits, and positive outcome expectancies of e-cigarette use among current e-cigarette users who reported at least one attempt to quit e-cigarettes but was unrelated among those who had never attempted to quit. DISCUSSION AND CONCLUSIONS: Findings identify e-cigarette users who fail to quit as a potential vulnerable subgroup of users who experience more strongly held perceptions about e-cigarettes because of increased AS. SCIENTIFIC SIGNIFICANCE: This work provides initial evidence for a conceptual model in which levels of AS and e-cigarette processes are strengthened by and differ across e-cigarette quit attempt history.
