Background: The use of heroin and prescription opioids has increased over the past decade. The concurrent use of opioids with other depressants such as benzodiazepines increases the risk of overdose death compared with use of either drug alone. This study examined factors associated with concurrent use of opioids and benzodiazepines in a criminal justice sample in the state of Alabama.

Anxiety sensitivity (AS) and the tendency to avoid emotions have both been identified as vulnerability factors for the development and maintenance of posttraumatic stress disorder (PTSD). Furthermore, both cross-sectional and prospective research have provided evidence that emotional avoidance and AS interact to predict anxiety symptoms, such that AS may only be associated with anxiety-related pathology among those who exhibit a tendency to avoid their emotions. The purpose of the present study was to determine if this moderator model extends to PTSD within a sample of substance dependent patients.

The purpose of the present study was to identify subgroups of participants who may be at particularly high risk for anxiety pathology based on specific combinations of demographic characteristics and higher-order cognitive abilities in a population at disproportionate risk for deficits in cognitive abilities (i.e., smokers within the criminal justice system).

Anxiety and substance use problems are common and often comorbid, and past research has shown that young adults in particular are especially at risk for developing these disorders. To further delineate the relationship between anxiety and substance use, the current study evaluated anxiety sensitivity (AS)-a cognitive vulnerability factor-as a moderator of the association between trait anxiety and illicit substance use in a large sample of young adults (N = 845; M = 18.7 years, SD = 1.

Self-discrepancy theory (SDT) is one framework for understanding how goal failure is associated with depressive symptoms. The present studies sought to examine the variance in depressive symptoms explained by actual:ideal discrepancies, beyond what is accounted for by actual-self ratings. Additionally, gender and grade were examined as potential moderators in the relationship.

Background And Objectives: Emotional avoidance has been found to be associated with higher levels of anxiety. However, no research to date has differentiated between the avoidance of positive and negative emotions in relation to anxiety. Additionally, no studies have examined the extent to which attentional control moderates the relation between the avoidance of emotions and anxiety.

Introduction: Racial and gender disparities for smoking cessation might be accounted for by differences in expectancies for tobacco interventions, but few studies have investigated such differences or their relationships with motivation to quit and abstinence self-efficacy.

Methods: In this cross-sectional study, 673 smokers (African American: n = 443, 65.8%; women: n = 222, 33.

Individual differences in higher-order cognitive abilities may be an important piece to understanding how and when self-discrepancies lead to negative emotions. In the current study, three measures of reasoning abilities were considered as potential moderators of the relationship between self-discrepancies and depression and anxiety symptoms. Participants (N = 162) completed measures assessing self-discrepancies, depression and anxiety symptoms, and were administered measures examining formal operational thought, and verbal and non-verbal abstract reasoning skills.

The use of antibiotic resistance analysis (ARA) for microbial source tracking requires the generation of a library of isolates collected from known sources in the watershed. The size and composition of the library are critical in determining if it represents the diversity of patterns found in the watershed. This study was performed to determine the size that an ARA library needs to be to be representative of the watersheds for which it will be used and to determine if libraries from different watersheds can be merged to create multiwatershed libraries.
