BACKGROUND: Increasing rates of cannabis use among emerging adults is a growing public health problem. Intensive longitudinal data can provide information on proximal motives for cannabis use, which can inform interventions to reduce use among emerging adults. METHOD: As part of a larger longitudinal study, patients aged 18-25 years (N=95) recruited from an urban Emergency Department completed daily text message assessments of risk behaviors for 28days, including daily cannabis quantity and motives...

Dextromethorphan (DXM) is one of the common drugs abused by adolescents. It is the active ingredient found in cough medicine which is used for suppressing cough. High dosage of DXM can induce euphoria, dissociative effects and even hallucinations. Chronic use of DXM may also lead to depressive-related symptoms. Lycium barbarum, commonly known as wolfberry, has been used as a traditional Chinese medicine for the treatment of ageing-related neurodegenerative diseases. A recent study has shown the potential beneficial effect of Lycium barbarum to reduce depression-like behavior...

Recent evidence suggests that reduced generosity among individuals with social anxiety disorder (SAD) in behavioral economic tasks may result from constraint in changing behavior according to interpersonal contingencies. That is, people with SAD may be slower to be more generous when the situation warrants. Conversely, more global effects on generosity may be related to interpersonal vindictiveness, a dimension only somewhat related to SAD. A total of 133 participants, 73 with the generalized form of SAD, completed self-report instruments and a behavioral economic task with simulated interpersonal (friend, romantic partner, stranger) interactions...

Cognitive behavior group therapy (CBGT) is effective for social anxiety disorder (SAD), but a substantial proportion of patients do not typically achieve normative functioning. Cognitive behavioral models of SAD emphasize negative self-imagery as an important maintaining factor, and evidence suggests that imagery is a powerful cognitive mode for facilitating affective change. This study will compare two group CBGT interventions, one that predominantly uses verbally-based strategies (VB-CBGT) and another that predominantly uses imagery-enhanced strategies (IE-CBGT), in terms of (a) efficacy, (b) mechanisms of change, and (c) cost-effectiveness...

REVIEW
Yong-Ku Kim, Ho-Kyoung Yoon
Although panic disorder (PD) and phobic disorders are independent anxiety disorders with distinct sets of diagnostic criteria, there is a high level of overlap between them in terms of pathogenesis and neural underpinnings. Functional connectivity research using resting-state functional magnetic resonance imaging (rsfMRI) shows great potential in identifying the similarities and differences between PD and phobias. Understanding common and distinct networks between PD and phobic disorders is critical for identifying both specific and general neural characteristics of these disorders...

Social anxiety disorder (SAD) is often treated as a discrete diagnostic entity that represents a naturally occurring class, though empirical evidence largely supports a dimensional conceptualization of social fears. Further, the inclusion of a "performance only" specifier in the DSM-5 implies that individuals who experience intense social anxiety exclusively in performance situations are distinct from those with broader social fears. The purpose of the present research was to examine the latent structure of SAD and the DSM-5 "performance only" specifier in a large nonclinical sample (n = 2019)...

Danielle Katz, Neil A Rector, Judith M Laposa
Distress tolerance (DT) and intolerance of uncertainty (IU) have been identified as transdiagnostic processes that predict symptom severity across a range of distinct anxiety disorders. However, the joint effect of these two variables on therapeutic outcome has not yet been examined. It is possible that DT and IU may both impact on treatment response to cognitive-behavioural therapy (CBT) in clients with anxiety, as clients with weak DT and strong IU may be less likely to engage in exposure and cognitive restructuring tasks across treatment due to their associated distress...

BACKGROUND: Comorbid psychiatric conditions present an added layer of challenge in managing patients, as each condition and associated set of symptoms exacerbate the complexity of the overall presentation. Premenopausal women may be at particular risk for inadequate care, as their comorbid conditions may present overlapping symptoms and mask independent premenstrual symptoms. The prevalence of premenstrual dysphoric disorder and associated conditions can be as high as 8% in women of reproductive age...

BACKGROUND: The mechanisms and triggers of the attentional bias in social anxiety are not yet fully determined, and the modulating role of personality traits is being increasingly acknowledged. AIMS: Our main purpose was to test whether social anxiety is associated with mechanisms of hypervigilance, avoidance (static biases), vigilance-avoidance or the maintenance of attention (dynamic biases). Our secondary goal was to explore the role of personality structure in shaping the attention bias...

BACKGROUND: Comorbidity of anxiety and depression (both current and lifetime) is associated with greater chronicity and an increased risk of suicidality. We wished to ascertain which symptom clusters had the strongest association with suicidality. Our aims were (1) to examine the presence of current comorbidity and suicidality in patients diagnosed with panic disorder/agoraphobia (PD/A) and major depression (MD), and their relationship with duration of psychiatric treatment and frequency of hospital admission; and (2) to examine which coexisting symptoms were most strongly predictive of suicidality in sub-groups and the overall group...

BACKGROUND: An overlap of clinical symptoms between major depressive disorder (MDD) and social anxiety disorder (SAD) suggests that the two disorders exhibit similar brain mechanisms. However, few studies have directly compared the brain structures of the two disorders. The aim of this study was to assess the gray matter volume (GMV) and cortical thickness alterations between non-comorbid medication-naive MDD patients and SAD patients. METHODS: High-resolution T1-weighted images were acquired from 37 non-comorbid MDD patients, 24 non-comorbid SAD patients and 41 healthy controls (HCs)...

This study investigated the psychometric properties of the Social Worries Anxiety Index for Young children (SWAIY), adapted from the Social Worries Questionnaire-Parent version (SWQ-P; Spence, 1995), as a measure of social anxiety in young children. 169 parents of children aged four to eight years from a community sample completed the SWAIY and a standardized measure of anxiety; the SWAIY was completed again two weeks later. Parents deemed the items appropriate and relevant to children of this age. The SWAIY demonstrated excellent (>0...

OBJECTIVE: One of the main characteristics of social anxiety disorder is excessive fear of social evaluation. In such situations, anxiety can influence gaze behaviour. Thus, the current study adopted virtual reality to examine eye gaze pattern of social anxiety disorder patients while presenting different types of speeches. METHODS: A total of 79 social anxiety disorder patients and 51 healthy controls presented prepared speeches on general topics and impromptu speeches on self-related topics to a virtual audience while their eye gaze was recorded...

Posttraumatic stress disorder (PTSD) and social anxiety disorder (SAD) frequently co-occur. Preliminary data from treatment-seeking and veteran samples suggest that the impact of PTSD-SAD comorbidity may be additive, conferring distress and impairment beyond that of either disorder alone. The current study sought to clarify and extend existent research using wave 2 of the National Epidemiologic Survey of Alcohol and Related Conditions, an epidemiological sample of American adults. Individuals who met criteria for comorbid PTSD-SAD were compared to those with either disorder alone on measures of lifetime suicide attempts or quality of life as measured by the Medical Outcomes Study Questionnaire...

Social anxiety is one of the most commonly reported mental health problems among adolescents, and it has been suggested that parenting style influences an adolescent's level of anxiety. A context-dependent effect of oxytocin on human social behavior has been proposed; however, research on the oxytocin gene (OXT) has mostly been reported without considering contextual factors. This study investigated the interactions between parenting style and polymorphic variations in the OXT gene in association with social anxiety symptoms in a community sample of adolescents (n = 1,359)...

BACKGROUND AND OBJECTIVES: Cognitive models of social anxiety disorder (SAD) emphasize anticipatory processing as a prominent maintaining factor occurring before social-evaluative events. While anticipatory processing is a maladaptive process, the cognitive mechanisms that underlie ineffective control of attention are still unclear. The present study tested predictions derived from attentional control theory in a sample of undergraduate students high and low on social anxiety symptoms...

OBJECTIVE: This study examined the effectiveness of manualized cognitive therapy (mCT) following the Clark-Wells approach versus non-manualized cognitive-behavioral treatment-as-usual (CBTAU) for social anxiety disorder (SAD) in routine practice. METHODS: Forty-eight private practitioners were recruited within a multi-center trial and either received training in manualized CT for SAD or no such training. Practitioners treated 162 patients with SAD in routine practice (N = 107 completers, n = 57 for mCT, n = 50 for CBTAU)...

This study examines psychophysiological and subjective reactivity to anxiety-provoking situations in relation to social anxiety and public speaking fear. We hypothesized that social anxiety symptoms would be associated with similar reactivity across types of imaginary anxiety scenes and not specifically to social anxiety-related scenes. This would be attributed to co-existing depression symptoms. Public speaking fear was expected to be associated with more circumscribed reactivity to survival-threat scenes, due to its association with fearfulness...
