Sexual orientation obsessions in obsessive-compulsive disorder: Prevalence and correlates

Sexual obsessions are a common symptom of obsessive-compulsive disorder (OCD) that may be particularly troubling to patients. However, little research has examined concerns surrounding sexual orientation, which includes obsessive doubt about one's sexual orientation, fears of becoming homosexual, or fears that others might think one is homosexual. The present study reports rates and related characteristics of individuals with sexual orientation obsessions in a clinical sample. Participants from the DSM-IV Field Trial (n = 409

TRY plant trait database – enhanced coverage and open access

Plant traits - the morphological, anatomical, physiological, biochemical and phenological characteristics of plants - determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits - almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

Anxiety Sensitivity and Smoking Topography: A Multi-Method Experimental Investigation

Introduction: Anxiety sensitivity, the tendency to catastrophically interpret the meaning of anxiety-relevant interoceptive sensations, is implicated in the acquisition and maintenance of anxiety symptoms/disorders and aspects of cigarette smoking. Smokers who tend to perceive interoceptive sensations as harmful or dangerous may be more likely to smoke for affect-regulatory purposes. The present study tested an experimental model of negative reinforcement-based smoking motivation by examining the extent to which laboratory-induced physiological arousal impacts smoking urges, craving, smoking topography (puff style), and the moderating role of anxiety sensitivity. Method: Adult daily smokers (n = 90; Mage = 43.6 [SD = 9.7]; average 15.8 cigarettes per day) were recruited to participate in a single-session experimental study. Participants were randomly assigned to complete a biological challenge procedure, used as an experimental emotion-provocation task that consisted of a single vital capacity inhalation of 35% CO2-enriched air mixture or compressed room air (control condition). Smoking urges and smoking topography (puff behavior) were assessed before and after the challenge. Results: Exposure to the 35% CO2-enriched air experimental condition, relative to room air, elicited significantly higher levels of subjective distress (b = 0.72, p = .013), panic attack symptoms (b = 1.13, p < .0001), heart rate (b = 0.14, p = .002), and respiration rate (b = 0.47, p < .038). All effects were medium to large in size (Cohen’s d range = 0.53 – 1.13). Results revealed a main effect of experimental condition in terms of self-report smoking urges post-challenge (b = -81.26, p = .048; d = -0.45), such that smokers exposed to the 35% CO2-enriched air reported significantly lower smoking urges post-challenge, relative to the room air condition. There was a significant interaction between anxiety sensitivity and experimental condition (b = -9.96, p = .014; d = -.56), such that high anxiety sensitive smokers exposed to 35% CO2-enriched air reported significantly lower levels of smoking urges, relative to low anxiety sensitive smokers, and anxiety sensitivity did not differentially impact smoking urges for those exposed to room air. Regarding smoking topography, results revealed a non-significant main effect of experimental condition in terms of latency to smoking initiation or average inter-puff interval post-challenge. There was a significant condition effect for average puff volume (b = -8.11, p = .048) and puff duration (b = -144.39, p = .050), such that exposure to 35% CO2-enriched air relative to room air, resulted in significantly smaller and shorter puff inhalations while smoking (Cohen’s d = -0.43). There were no significant interaction effects of experimental condition by anxiety sensitivity for any of the smoking topography outcomes. Discussion: The experience of abrupt physiological distress may immediately result in decreased subjective smoking urges and changes in puff behavior (smaller volume; shorter duration), likely due to intensity of the cardiorespiratory distress experienced from the 35% CO2-enriched air manipulation. This appeared to be particularly true for smokers high in anxiety sensitivity, at least in the case of subjective smoking urges. Findings are contextualized with the existing literature examining mechanistic factors linking panic attacks and smoking.Psychology, Department o

The Role of Depressive and Panic Symptoms in Predicting Cannabis Use Cognitive Processes and Quit Behavior

Despite the high rates of anxiety/mood disorders among cannabis dependent individuals, there is little research on the role of panic and depressive symptoms among Veterans – a population with high rates of substance use-anxiety and mood comorbidity. The current study examined the main and interactive effects of panic and depressive symptoms on maladaptive expectations and motives for cannabis use, cannabis-related problems, and quit behavior among cannabis-dependent Veterans. Method: Participants (n = 100) were cannabis dependent Veterans participating in a cannabis self-guided quit study. Panic/depressive symptoms were assessed prior to the quit-attempt using two subscales of the Inventory of Depression and Anxiety Symptoms (IDAS); expectancies were assessed using the Marijuana Effect Expectancies Questionnaire–Tension Reduction/Relaxation subscale (MEEQ); motives were assessed using the Marijuana Motives Questionnaire–Coping subscale (MMQ). Pre-quit cannabis-use problems were assessed with the Marijuana Problems Scale (MPS); Substance use prior and following the quit-attempt was assessed with the Timeline Follow-Back (TLFB). A series of hierarchical regression-based models were conducted: Pre-quit cannabis and other substance use were entered as covariates, followed by the main effects of IDAS subscales, then the interaction. Results: The interaction term significantly predicted MEEQ-Tension Reduction/Relaxation, with highest scores reported among those with high IDAS-Depression and Panic scores. The interaction term also was significantly predictive of MMQ-Coping, and was highest among those with high IDAS-Depression and low IDAS-Panic scores. IDAS-Depression was uniquely predictive of greater cannabis problems on the MPS. Regarding quit behavior, IDAS-Panic was marginally predictive of time to relapse in the first 28 days post-quit attempt, with higher scores predicting an increased risk for relapse. Additionally, IDAS-Panic significantly interacted with time to predict fewer percent days abstinent and more cannabis use per use occasion during follow-up. Conclusion: Findings are discussed in relation to the existing literature on anxiety/depressive symptoms in relation to cannabis use processes and quit behavior.Psychology, Department o

Linguistic analysis of health anxiety during the COVID-19 pandemic.

Health anxiety, which is defined as fear of having or contracting serious physical illness, is particularly salient in light of the COVID-19 pandemic. We conducted a mixed methods study in which 578 narrative samples were analyzed using Linguistic Inquiry and Word Count (LIWC) software to determine linguistic markers from six LIWC categories relevant to cognitive-behavioral features of health anxiety. Broad linguistic predictors were analyzed through three backward elimination regression models in order to inform subcategory predictors of each area of health anxiety. Thus, both broad and specific linguistic predictors of general health anxiety, virus-relevant body vigilance, and fears of viral contamination were examined. Greater use of affective category words in written narratives predicted general health anxiety, as well as body vigilance and viral contamination fears. These findings represent the first direct demonstration of linguistic analysis of health anxiety and provide nuanced information about the nature and etiology of health anxiety

The effect of anxiety sensitivity on alcohol consumption among individuals with comorbid alcohol dependence and posttraumatic stress disorder

Existing research has shown that anxiety sensitivity (AS) is positively associated with alcohol use and that individuals with high AS use alcohol to avoid or escape negative affect associated with aversive stimuli. The current study investigated the associations between AS and drinking behavior among individuals with comorbid alcohol dependence and posttraumatic stress disorder (PTSD). We assessed baseline PTSD symptoms, AS, and drinking behavior among participants (N = 151) who were enrolled in a randomized clinical trial for alcohol dependence. We hypothesized that AS would moderate the association between PTSD symptoms and drinking behavior, with PTSD symptoms being more strongly associated with drinking behavior among individuals with high AS. Results showed that AS was strongly associated with PTSD (r = .48) and moderately associated with drinking behavior (r = .18). As predicted, the interaction of AS with severity of PTSD symptoms was associated with frequency of drinking; however, contrary to our hypothesis, PTSD symptoms were more strongly associated with drinking behavior among individuals with relatively low AS. The implication of the present results for treatment of both PTSD and alcohol dependence are discussed

Direct and indirect associations between social anxiety and nicotine dependence and cessation problems: multiple mediator analyses

INTRODUCTION: Little empirical work has evaluated why socially anxious smokers are especially vulnerable to more severe nicotine dependence and cessation failure. Presumably, these smokers rely on cigarettes to help them manage their chronically elevated negative affect elicited by a wide array of social contexts. METHODS: The current study examined the direct and indirect effects of social anxiety cross-sectionally in regard to a range of smoking processes among 466 treatment-seeking smokers. Negative affect and negative affect reduction motives were examined as mediators of the relations of social anxiety with nicotine dependence and cessation problems. RESULTS: Social anxiety was directly and robustly associated with perceived barriers to smoking cessation and problems experienced during past quit attempts. Social anxiety was also associated with greater nicotine dependence and smoking inflexibility indirectly through negative affect and negative affect smoking motives. Negative affect and smoking to reduce negative affect mediated these relations. CONCLUSIONS: These findings document the important role of negative affect and negative affect reduction motives in the relationships of social anxiety with nicotine dependence and cessation problems
