RESUMEN

Purpose: The current study examined functional health literacy (FHL) in regard to hazardous drinking among a sample with probable posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD). Methods: Participants were 565 adults with probable PTSD and hazardous alcohol use (52.2% female, 68.8% Non-Hispanic White, average age = 39.2 years ± 10.9 years). Results: FHL literacy maintained statistically significant role in terms of hazardous drinking (p < .001) even in the context of posttraumatic stress. Conclusion: FHL may be important to better understand hazardous drinking among persons with comorbid PTSD and AUD.

RESUMEN

The negative impact of the COVID-19 pandemic on mental health outcomes is widely documented. Specifically, individuals experiencing greater degrees of severity in coronavirus anxiety have demonstrated higher levels of generalized anxiety, depression and psychological distress. Yet the pathways in which coronavirus anxiety confers vulnerability are not well known. The present investigation sought to address this gap in the scientific literature by testing the indirect effect of the COVID-19 anxiety syndrome, which centres on the function of detecting and managing the environmental threat of virus exposure and its sequalae. Data were collected during the height of the pandemic (March 2021) and included 5297 adults across six countries. Structural equation modelling techniques revealed that the COVID-19 anxiety syndrome evidenced a statistically significant indirect effect between coronavirus anxiety and generalized anxiety, depression and work/social adjustment. Overall, results suggest there could be public health merit to targeting anxiety related to virus exposure to improve behavioural health for those who are struggling with excessive fear and worry.

RESUMEN

OBJECTIVES: The intention of this study was to characterize the real-time momentary relationship between emotion regulation strategies and the pain experience (ie intensity, interference, and negative affect) among adults with chronic pain. Chronic pain is a significant public health concern. Psychological treatments are effective for treating chronic pain, but long-term follow-up studies are limited, and treatment effect sizes are small. Identifying modifiable treatment targets, such as emotion regulation (ER), is critical to improve interventions. ER (ie, cognitive and attentional strategies to modulate or maintain emotional experience) has been linked to psychopathology and pain experience in adults. Yet, the existing work is limited and has largely focused on the relationship between emotional experience, not ER, and pain. MATERIALS AND METHODS: The current study utilized ecological momentary assessment 53 adults with chronic pain. Participants completed ecological momentary assessments of pain experience and ER strategies 5 times a day for 7 days. Associations by specific strategy type were also examined, highlighting the importance of worry, experiential avoidance, rumination, and expressive suppression in pain experience. RESULTS: Results of the current study provide evidence for the association between within-person maladaptive ER strategies and pain intensity ( b = 2.11, SE = 0.37, P < 0.001), pain interference ( b = 1.25, SE = 0.40, P = 0.002), and pain-related negative affect ( b = 2.20, SE = 0.41, P < 0.001). (77.4% females; M age = 27.10 y, SD = 5.16 y). DISCUSSION: Given that ER is readily targeted in psychological treatments for chronic pain, the results from the current study provide initial evidence to target these ER strategies in treatment.

RESUMEN

Electronic cigarette (e-cigarette) use has become increasingly common among combustible cigarette users, and dual use may represent a more severe type of nicotine addiction. Experiencing pain is one prevalent domain that may be important to understand quit processes and behavior among dual users. Although most past research on pain and nicotine/tobacco has focused on combustible cigarette use, initial work on e-cigarette users has found that greater pain severity is associated with higher levels of dependence and negative thinking patterns about e-cigarette use. Yet, there has been no effort to explore the experience of pain among dual users in terms of perceived barriers for quitting combustibles or e-cigarettes. The present study sought to examine pain interference among dual combustible and e-cigarette users in terms of perceived barriers for quitting among 138 (45.9% female; Mage = 35.96 years, SD = 7.16) adult dual users (i.e., users of both combustible cigarette and e-cigarettes). Hierarchical linear regression models indicated that pain interference was significantly associated with both perceived barriers for cessation of combustible cigarettes and perceived barriers for cessation of e-cigarettes. Overall, the present investigation served as an initial evaluation of the role of pain interference in terms of perceived barriers for quitting combustible and e-cigarettes among adult daily dual users.

RESUMEN

OBJECTIVE: Black individuals who smoke in the United States experience significant tobacco-related disparities. Although prior work has established that smoking abstinence expectancies play an important role in smoking-related outcomes, few studies have examined potential individual difference factors that may be relevant to smoking abstinence expectancies among Black individuals who smoke. The present study investigated anxiety sensitivity and distress tolerance in relation to smoking abstinence expectancies among a sample of Black individuals who smoke. METHOD: Participants were 86 Black adults who smoke cigarettes daily (M age = 46.07 years, SD = 10.37; 26.7% female). Four separate linear regression analyses were conducted to evaluate the relation between anxiety sensitivity, distress tolerance, and their interaction with each of the four smoking abstinence expectancies (i.e., somatic symptoms, positive consequences, harmful consequences, and negative mood). RESULTS: Results indicated that higher anxiety sensitivity was related to higher somatic symptoms, harmful consequences, and negative mood abstinence expectancies, whereas distress tolerance was related to higher positive consequences. Further, anxiety sensitivity and distress tolerance interacted to confer greater expectancies for the positive consequences of quitting. CONCLUSIONS: The current findings are among the first to document that anxiety sensitivity and distress tolerance are clinically relevant factors to consider when tailoring smoking cessation treatments for Black individuals who smoke. Future research is needed to examine distress tolerance and anxiety sensitivity as longitudinal predictors of smoking abstinence expectancies among Black individuals who smoke.

RESUMEN

INTRODUCTION: Latino individuals are underrepresented in the disorders of the gut-brain interaction (DGBI) literature, and no work has explored how disorders of the gut-brain interaction affect health and well-being in this group. METHODS: This study sought to explore how disorders of the gut-brain interaction affect health factors in a sample of Latino individuals (N = 292; 80.80% female; M age = 37.65 years, SD = 11.98) with (n = 60) and without (n = 232) a disorder of the gut-brain interaction based on current Rome Foundation diagnostic criteria (Rome IV). RESULTS: DGBI was associated with increased pain intensity, pain disability, cardiovascular risk, depressive symptoms, and anxiety/panic symptoms and lower physical health-related quality of life and mental health-related quality of life controlling for age, sex, and nativity. DISCUSSION: Better understanding mental health and treatment-seeking behaviors among Latino individuals may help clinical gastroenterologists engage their Latino patients to a greater extent and thus provide higher quality of care.

RESUMEN

Background: Latinx individuals experience significant tobacco cigarette smoking-related diseases and illnesses. Although most Latinx smokers report a desire to quit smoking, evidenced-based cessation treatments are underutilized in this group, which may partially be due to lower likelihood of receiving advice from a healthcare professional. Further, there are a lack of cessation treatments that account for comorbid symptoms/conditions (e.g., co-occurring pain) and social determinants of health (e.g., perceived discrimination). Extant work has established the reciprocal relation between pain and smoking trajectories. Additionally, although social determinants, such as perceived racial/ethnic discrimination, have demonstrated clinical relevance to a variety of health-related behaviors, limited work has examined the role of perceived discrimination in pain-smoking relations. The current study examined the effects of perceived discrimination and pain severity in relation to smoking cessation problems and self-efficacy for quitting among Latinx cigarette smokers. Method: Participants included 226 (Mage = 34.95 years, SD = 8.62; 38.5% female) adult Latinx daily cigarette smokers. Results: Results indicated that the interaction of pain and perceived discrimination was predictive of greater quit problems (p = 0.041) as well as greater confidence in the ability to refrain from smoking in response to internal (p < 0.001) and external stimuli (p < 0.001). Conclusions: Overall, this work provides a more nuanced understanding of the psychosocial contexts in which Latinx smokers may encounter problems related to quitting, and this data is important for future smoking cessation research and treatment.

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

Scientific evidence suggests that smokers who experience varying levels of pain are more likely to maintain their addiction to tobacco. The relationship between pain intensity and cognitive-based smoking processes within a mechanistic framework has received relatively little attention. Pain avoidance may influence the association between pain intensity and smoking, as it is a construct that is related to adverse pain and smoking processes. Thus, the current cross-sectional study examined the indirect effect of pain intensity on three clinically significant smoking processes (i.e., prior quit problems, perceived barriers for cessation, and negative affect reduction smoking expectancies) through pain avoidance among 95 treatment-seeking adult smokers. Regression analyses were conducted using bootstrapping techniques through PROCESS, a conditional modeling program that utilizes an ordinary least squares-based path analytical framework to test for both direct and indirect associations. Results indicated that pain intensity had a statistically significant indirect association with quit problems and perceived barriers for cessation, through pain avoidance. Pain intensity did not have a statistically significant indirect association with the negative affect reduction of smoking expectancies through pain avoidance. The current findings provide evidence for the role of pain avoidance as a potential transdiagnostic mechanism that contributes to maladaptive smoking outcomes within the larger context of the reciprocal model of pain and substance use.

RESUMEN

Latinx individuals who smoke represent a tobacco health disparities group. Yet, limited research has focused on examining dual combustible and electronic cigarette use among Latinx populations. Importantly, Latinx persons who smoke also evince elevated rates of pain problems and symptoms and prior research has consistently linked pain problems and severity to smoking prevalence, maintenance, and behavior. Accordingly, the current study sought to build from the limited work that exists among dual combustible cigarette and electronic cigarette Latinx users comparing levels of pain severity and interference. The current sample consists of 196 adult Latinx daily cigarette smokers (35.48 years old; 39.4% female), of which 72 reported current daily dual use of an e-cigarette. Results indicated that Latinx dual users reported greater levels of pain severity (ηp2 = .12) and pain interference (ηp2 = .10) than exclusive combustible cigarette users. The study adds uniquely to the limited literature on the clinical importance of dual cigarette use in relation to pain severity and interference in that pain may serve as an important risk factor for the initiation and maintenance of dual use for increased analgesic nicotine effects.

RESUMEN

Limited research has focused expressly on dual tobacco-alcohol use among the Latinx population. Latinx individuals who smoke represent a tobacco health disparities group and evince elevated rates of pain problems and symptoms. Prior research has consistently linked pain problems and severity to smoking and alcohol prevalence, maintenance, and behavior. Accordingly, the current study sought to build from the limited work that exists among Latinx persons who smoke and evaluate the role of alcohol use severity in terms of pain severity and interference. The current sample consisted of 228 adult Latinx daily cigarette smokers (Mage = 34.95 years; SD = 8.58; 39.0% female) who endorsed current pain. Results indicated that elevated alcohol use problems were associated with greater levels of pain severity (R2 = 0.06) and interference (R2 = 0.06). The present findings suggest that there may be utility in clinical screening for alcohol use problems among Latinx persons who smoke to offset pain problems among this high-risk group.

RESUMEN

Objective: The high comorbidity between posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) is well-established and complex. However, there is a need to explore transdiagnostic constructs that may underlie this association to better understand what accounts for this comorbidity and to inform treatment development. Method: Thus, the present study utilized a large, cross-sectional dataset (N = 513; Mage = 38.25 years, SD = 10.07; 49.9% female), based on national recruitment, to (1) examine whether the associations between PTSD symptom severity (PCL-5) and alcohol use severity (AUDIT) were statistically mediated by (a) anxiety sensitivity (SSASI); and (b) difficulties with emotion regulation (DERS-16); and (2) examine whether coping motives for drinking moderate this indirect effect. Sex assigned at birth was included as a covariate. Results: When examining the hypothesized mediators (SSASI and DERS-16) in separate models, there was a statistically significant indirect effect of PCL-5 on AUDIT through both SSASI and DERS. However, when both SSASI and DERS were entered into a model simultaneously, only SSASI served as a statistically significant mediator. Coping motives for drinking did not moderate the observed indirect effect. Conclusions: The current findings highlight anxiety sensitivity and emotion regulation as transdiagnostic processes that may explain, at least partially, the relationship between PTSD symptom severity and alcohol use; however, stronger evidence was evident for anxiety sensitivity. These findings may help inform the development of refined, streamlined interventions for PTSD and alcohol use that directly target these processes.

RESUMEN

Chronic low back pain (CLBP) is a significant public health problem that is associated with opioid misuse and use disorder. Despite limited evidence for the efficacy of opioids in the management of chronic pain, they continue to be prescribed and people with CLBP are at increased risk for misuse. Identifying individual difference factors involved in opioid misuse, such as pain intensity as well as reasons for using opioids (also known as motives), may provide pertinent clinical information to reduce opioid misuse among this vulnerable population. Therefore, the aims of the current study were to examine the relationships between opioid motives-to cope with pain-related distress and pain intensity, in terms of anxiety, depression, pain catastrophizing, pain-related anxiety, and opioid misuse among 300 (Mage= 45.69, SD = 11.17, 69% female) adults with CLBP currently using opioids. Results from the current study suggest that both pain intensity and motives to cope with pain-related distress with opioids were associated with all criterion variables, but the magnitude of variance explained by coping motives was larger than pain intensity in terms of opioid misuse. The present findings provide initial empirical evidence for the importance of motives to cope with pain-related distress with opioids and pain intensity in efforts to better understand opioid misuse and related clinical correlates among adults with CLBP.

RESUMEN

Background: Opioid misuse in the context of pain management exacts a significant public health burden. Past work has established linkages between negative mood (i.e., symptoms of anxiety and depression) and opioid misuse/dependence, yet the mechanisms underlying these associations have received little scientific investigation. Anxiety sensitivity (AS), the fear of the negative consequences of internal states, may be relevant to better understanding negative mood-opioid relations among adults with chronic pain. Methods: Simultaneous indirect effects of negative mood on opioid misuse and opioid dependence via lower-order factors of AS (physical, cognitive, and social concerns) were examined cross-sectionally in the present study. The study sample consisted of 428 adults (74.1% female, Mage = 38.27 years, SD = 11.06) who self-reported current moderate to severe chronic pain and opioid use for chronic pain. Results: Results indicated that negative mood was (in part) indirectly related to opioid misuse (in part) via AS physical and cognitive concerns and was (in part) indirectly related to opioid dependence via AS cognitive concerns only. No significant indirect effects via social concerns were observed. Discussion and Conclusions: Findings suggest the importance of further exploring the role of anxiety sensitivity cognitive and physical concerns in terms of opioid misuse and dependence among adults with chronic pain.

RESUMEN

Latinx individuals experience significant health disparities related to smoking cessation in the United States (US). Although past works have consistently implicated pain in the maintenance of smoking behavior, limited research has examined the role of social determinants (e.g., perceived discrimination) in pain-smoking relations. The current study sought to examine the moderating role of perceived discrimination in the relation between pain severity and smoking abstinence expectancies (i.e., a cognitive factor related to poor smoking outcomes) among 226 Latinx individuals who currently smoke cigarettes (Mage = 34.95 years; SD = 8.62; 38.5% female). The results indicated a statistically significant interaction between pain severity and perceived discrimination with regard to smoking abstinence expectancies (i.e., negative mood, somatic symptoms, harmful consequences, and positive consequences). Post-hoc analyses revealed the association of pain severity and negative mood, harmful consequences, and positive consequences smoking abstinence expectancies evident for individuals with higher perceived discrimination. Moreover, the association between pain severity and somatic symptoms smoking abstinence expectancies was stronger for individuals with higher perceived discrimination. Overall, these results suggest that clinical and community-based public health strategies may benefit from addressing the role of perceived discrimination among Latinx individuals who smoke cigarettes in the context of pain.

RESUMEN

Black smokers demonstrate higher nicotine dependence and experience higher rates of smoking-related diseases and mortality relative to European American/White smokers. A potential factor relevant to race-specific smoking health disparities may be smoking motives (i.e., motivational basis of smoking). Yet, little research has been conducted to understand psychological factors that may be associated with specific smoking motives among Black smokers. To address this gap in the literature, the current study explored the association between anxiety sensitivity and smoking motives within a subset sample of Black smokers who were interested in participating in a smoking cessation trial (N = 105; 70.5 % male; Mage = 44.8 years, SD = 11.6 years). Hierarchical regression analyses indicated anxiety sensitivity was associated with smoking motives related to habit (ß = 0.39, p <.001), negative affect reduction (ß = 0.32, p <.001), stimulation (ß = 0.31, p <.001), and sensorimotor manipulation (ß = 0.26, p =.008). Limited support was found for the effect of motives on past quit attempt engagement. These results may broaden understanding of the psychological mechanisms related to smoking motivation among Black smokers and may inform future intervention efforts to reduce smoking motivation among this health disparities population.

RESUMEN

Rationale: Pretomanid is a new nitroimidazole with proven treatment-shortening efficacy in drug-resistant tuberculosis. Pretomanid-rifamycin-pyrazinamide combinations are potent in mice but have not been tested clinically. Rifampicin, but not rifabutin, reduces pretomanid exposures. Objectives: To evaluate the safety and efficacy of regimens containing pretomanid-rifamycin-pyrazinamide among participants with drug-sensitive pulmonary tuberculosis. Methods: A phase 2, 12-week, open-label randomized trial was conducted of isoniazid and pyrazinamide plus 1) pretomanid and rifampicin (arm 1), 2) pretomanid and rifabutin (arm 2), or 3) rifampicin and ethambutol (standard of care; arm 3). Laboratory values of safety and sputum cultures were collected at Weeks 1, 2, 3, 4, 6, 8, 10, and 12. Time to culture conversion on liquid medium was the primary outcome. Measurements and Main Results: Among 157 participants, 125 (80%) had cavitary disease. Median time to liquid culture negativity in the modified intention-to-treat population (n = 150) was 42 (arm 1), 28 (arm 2), and 56 (arm 3) days (P = 0.01) (adjusted hazard ratio for arm 1 vs. arm 3, 1.41 [95% confidence interval (CI), 0.93-2.12; P = 0.10]; adjusted hazard ratio for arm 2 vs. arm 3, 1.89 [95% CI, 1.24-2.87; P = 0.003]). Eight-week liquid culture conversion was 79%, 89%, and 69%, respectively. Grade ≥3 adverse events occurred in 3 of 56 (5%), 5 of 53 (9%), and 2 of 56 (4%) participants. Six participants were withdrawn because of elevated transaminase concentrations (five in arm 2, one in arm 1). There were three serious adverse events (arm 2) and no deaths. Conclusions: Pretomanid enhanced the microbiologic activity of regimens containing a rifamycin and pyrazinamide. Efficacy and hepatic adverse events appeared highest with the pretomanid and rifabutin-containing regimen. Whether this is due to higher pretomanid concentrations merits exploration. Clinical trial registered with www.clinicaltrials.gov (NCT02256696).

RESUMEN

The opioid epidemic is a significant public health concern, and opioid consumption rates and opioid-related deaths are on the rise. Chronic pain acceptance, or willingness to experience pain and pain-related distress, is one pain-related psychological mechanism that may reduce maladaptive attempts to avoid or control pain using opioids among individuals with chronic lower back pain (CLBP). However, little work has examined chronic pain acceptance as it relates to opioid use and motives for use among adults with CLBP. The current investigation sought to explore the effects of chronic pain acceptance on opioid misuse and motives for opioid use (i.e., pain management and coping motives) among adults with CLBP. Participants were 291 adults (69.1 % female, Mage = 45.77 years, SD = 11.22) self-reporting current mild to severe CLBP and current opioid use who were recruited via an online survey. Results indicated that higher acceptance of pain was related to lower levels of opioid misuse and lower motivation to use opioids to cope with pain. Contrary to hypotheses, chronic pain acceptance did not predict motivation to use opioids to cope with emotional distress (i.e., coping motives). The current findings provide support for chronic pain acceptance as a potential protective mechanism in terms of opioid misuse and motivation to use opioids to manage pain.

RESUMEN

Black individuals who smoke in the United States experience health disparities related to tobacco use (e.g., greater nicotine dependence, less success in quitting smoking) and interoceptive distress (e.g., somatic symptoms, anxiety). Individual difference factors that amplify interoceptive distress and contribute to poorer smoking behaviors and outcomes warrant further attention and investigation. Thus, the present study sought to explore the association between anxiety sensitivity and clinically-relevant smoking variables of perceived barriers for quitting, smoking inflexibility, and problems experienced during past quit attempts. Participants in the current study included 98 Black adult smokers (71.4% male; Mage = 44.08 years, SD = 11.44 years). Results indicated greater levels of anxiety sensitivity were associated with greater levels of perceived barriers for quitting smoking (b = 0.10, SE = 0.08, p = 0.01), smoking inflexibility (b = 0.02, SE <.001, p <.001), and problems experienced during past smoking quit attempts (b = 0.17, SE = 0.07, p = 0.02). Clinical implications and future directions are further discussed as it relates to anxiety sensitivity and efforts to reduce or quit smoking for this health disparities population.

RESUMEN

With a direct link between traumatic stress and poor smoking outcomes established, there is a clinically important need to identify underlying, targetable mechanisms that maintain these relations. The present study employed a parallel mediation model to assess the competing explanatory significance of four distinct facets of depression and anxiety (general anxiety, anxious arousal, general depression, and anhedonic depression) in the relation between traumatic load and perceived barriers for quitting smoking, severity of psychosomatic problems experienced when attempting to quit smoking in the past, and negative reinforcement expectancies related to smoking among 98 adult trauma-exposed daily smokers (Mage = 44.64, SD = 10.66). Results showed that only general anxiety symptoms, when controlling for the competing facets of depression and anxiety, had a statistically significant indirect effect on the relation between traumatic load and all smoking processes, such that general anxiety symptoms significantly, indirectly influenced the relation between traumatic load and barriers for smoking cessation (ab = 0.95, 95% CI [0.163, 0.2.14]), smoking quit problems (ab = 0.07, 95% CI [0.009, 0.165]), and negative reinforcement smoking expectancies (ab = 0.16, 95% CI [0.025, 0.399]). Anxious arousal demonstrated an indirect effect for trauma load on only negative reinforcement smoking expectancies (ab = -0.15, 95% CI [-0.345, -0.023]). The current findings highlight the potential importance of general anxiety symptoms as a targetable mechanism for smoking cessation treatments for trauma-exposed smokers.
