“…Exclusion criteria were: (a) suicidal risk in the past two weeks ascertained with items from the Suicidality Scale of the Inventory of Depression and Anxiety Symptoms (Watson et al, 2007) and clinical interview; (b) psychotic symptoms in the past month assessed by the Structured Clinical Interview for DSM-IV Non-Patient Edition (SCID-IV-NP; First, Spitzer, Gibbon, & Williams, 2002); (c) score ≤ 23 on the Mini-Mental Status Exam (Folstein, Folstein, & McHugh, 1975); or (d) active duty at the time of the baseline assessment (due to increased likelihood of study dropout due to deployment). The study was approved by the Institutional Review Boards of Brown University and the Providence VHA.…”

Veterans with posttraumatic stress disorder (PTSD) and major depressive disorder (MDD), the two most prevalent mental health disorders in the Iraq and Afghanistan veterans, are at increased risk for cannabis use and problems including cannabis use disorder (CUD). The present study examined the relationship of PTSD and MDD with cannabis use frequency, cannabis problems, and CUD as well as the role of three coping-oriented cannabis use motives (coping with negative affect, situational anxiety, and sleep) that might underlie this relationship. Participants were veterans (N = 301) deployed post 9/11/2001 recruited from Veterans Health Administration facility in the Northeast US based on self-reported lifetime cannabis use. There were strong unique associations between PTSD and MDD and cannabis use frequency, cannabis problems, and CUD. Mediation analyses revealed the three motives accounted, in part, for the relationship between PTSD and MDD with three outcomes in all cases but for PTSD with cannabis problems. When modeled concurrently, sleep motives, but not situational anxiety or coping with negative affect motives, significantly mediated the association between PTSD and MDD with use. Together with coping motives, sleep motives also fully mediated the effects of PTSD and MDD on CUD and in part the effect of MDD on cannabis problems. Findings indicate the important role of certain motives for better understanding the relation between PTSD and MDD with cannabis use and misuse. Future work is needed to explore the clinical utility in targeting specific cannabis use motives in the context of clinical care for mental health and CUD.

“…In addition to providing total depression and dysthymia scores, the IDAS yields 10 symptom subscales including: suicidality, lassitude, insomnia, appetite loss, appetite gain, ill-temper, well-being, panic, social anxiety, and traumatic intrusions. Prior research has demonstrated that the IDAS has excellent psychometric properties including internal consistently, test-retest reliability, and convergent and discriminant validity (Watson et al, 2007). …”

Background One of the hallmark features of major depressive disorder (MDD) is reduced reward anticipation. There have been mixed findings in the literature as to whether reward anticipation deficits in MDD are related to diminished mesolimbic activation and/or enhanced dorsal anterior cingulate activation (dACC). One of the reasons for these mixed findings is that these studies have typically not addressed the role of comorbid anxiety, a class of disorders which frequently co-occur with depression and have a common neurobiology. Methods The aim of the current study was to examine group differences in neural responses to reward anticipation in 40 adults with either: 1) current MDD with no lifetime diagnosis of an anxiety disorder (MDD-only), 2) current MDD with comorbid panic disorder (MDD-PD), or 3) no lifetime diagnosis of psychopathology. All participants completed a passive slot machine task during a functional magnetic resonance imaging (fMRI) scan. Results Analyses indicated that there were no group differences in activation of mesolimbic reward regions; however, the MDD-only group exhibited greater dACC activation during the anticipation of rewards compared with the healthy controls and the comorbid MDD-PD group (who did not differ from each other). Limitations The sample size was small which limits generalizability. Conclusions These findings provide preliminary support for the role of hyperactive dACC functioning in reduced reward anticipation in MDD. They also indicate that comorbid anxiety may alter the association between MDD and neural responding to reward anticipation.

“…The dysphoria subscale (10 items; possible range 10–50) assesses anhedonia, sadness, psychomotor disturbance, worthlessness, worry, cognitive difficulty. The IDAS has strong psychometric properties, including internal consistency, test-retest reliability, and convergent and discriminant validity (Watson et al 2007) (16). Internal consistency for the Dysphoria subscale in the current study was excellent (α = 0.92).…”

“…It is possible that certain elements of MDD and depressive symptoms play a larger role in smoking than others, which may obscure research that utilizes the MDD diagnosis or composite measures that amalgamate all depressive symptoms into a single index. Recent research suggests depressive symptoms are not unifactorial and that certain specific symptoms of depression load onto a common dysphoria dimension characterized by anhedonia, sadness, psychomotor disturbance, loss of self-esteem, cognitive difficulty, and worry (16). Dysphoria, which may reflect core affective, cognitive, and psychomotor features of depression, may be more related to smoking maintenance and relapse than other depressive symptoms such as appetite changes, sleep problems, irritability, fatigue, and social difficulties (17–19).…”

Background Emerging data suggest that dysphoria is one facet of depression that is especially related to various aspects of cigarette smoking. However, it is presently unknown what emotional processes may account for these relations. Objectives In the current cross-sectional study, the impact of avoidance and inflexibility to smoking (AIS), a smoking-specific form of experiential avoidance, was tested on the relationship of dysphoria to four specific smoking processes that are key factors in cessation: perceived barriers to cessation, severity of problems during prior quit attempts, negative reinforcement smoking expectancies, and motivation to quit smoking. Methods Participants (n = 465) were treatment-seeking adult daily smokers. Relative indirect effects were subjected to bootstrap analyses to test direct and indirect effects of dysphoria on smoking processes. Results After controlling for gender, nicotine dependence severity, drinking problems, cannabis use, negative affectivity, tobacco-related medical problems, and AIS, dysphoria remained directly, positively related to perceived barriers and cessation problems. Additionally, dysphoria was indirectly, positively related to perceived barriers, cessation problems, negative reinforcement smoking expectancies, and motivation to quit indirectly through higher levels of AIS. Conclusion In the context of dysphoria, AIS may explain a wide range of clinically-relevant smoking processes.
