Antidepressant Use in a 3- to 12-Year Follow-up of Anxious Youth: Results from the CAMELS Trial.

The current study explored whether patient characteristics predicted patterns of antidepressant use (i.e., never used, single episode of use, or two or more episodes) in a naturalistic follow-up. Participants in the child/adolescent multimodal (CAMS) extended long-term study. (n = 318) indicated medication use over the course of eight follow-up visits, 3-12 years after receiving treatment in CAMS. 40.6% of participants reported never using an antidepressant during follow-up, 41.4% reported a single episode of antidepressant use, and 18.0% reported multiple episodes of antidepressant use. Greater baseline anxiety severity marginally predicted a single episode of antidepressant use; baseline depression severity predicted multiple episodes of use. Reasons for discontinuing antidepressants included perceived ineffectiveness (31.8%), side effects (25.5%), and improvement in symptoms (18.5%). Exploratory analyses examined predictors of medication use. Findings suggest that antidepressant use is common among anxious youth, as is discontinuation of antidepressant use. Clinical implications and future directions are discussed.

Integrating evidence-based assessment into clinical practice for pediatric anxiety disorders.

BACKGROUND: Although evidence-based assessments are the cornerstone of evidence-based treatments, it remains unknown whether incorporating evidence-based assessments into clinical practice enhances therapists' judgment of therapeutic improvement. This study examined whether the inclusion of youth- and parent-reported anxiety rating scales improved therapists' judgment of treatment response and remission compared to the judgment of treatment-masked independent evaluators (IEs) after (a) weekly/biweekly acute treatment and (b) monthly follow-up care. METHODS: Four hundred thirty six youth received cognitive-behavioral therapy (CBT), medication, CBT with medication, or pill placebo through the Child/Adolescent Anxiety Multimodal Study. Participants and parents completed the following anxiety scales at pretreatment, posttreatment, and follow-up: Screen for Childhood Anxiety and Related Disorders (SCARED) and Multidimensional Anxiety Scale for Children (MASC). IEs rated anxiety on the Clinical Global Impression of Severity (CGI-S) and Improvement (CGI-I) at posttreatment and follow-up. Therapists rated anxiety severity and improvement using scales that paralleled IE measures. RESULTS: Fair-to-moderate agreement was found between therapists and IEs after acute treatment (κ = 0.38-0.48), with only slight-to-fair agreement found after follow-up care (κ = 0.07-0.33). Optimal algorithms for determining treatment response and remission included the combination of therapists' ratings and the parent-reported SCARED after acute (κ = 0.52-0.54) and follow-up care (κ = 0.43-0.48), with significant improvement in the precision of judgments after follow-up care (p < .02-.001). CONCLUSION: Therapists are good at detecting treatment response and remission, but the inclusion of the parent-report SCARED optimized agreement with IE rating-especially when contact was less frequent. Findings suggest that utilizing parent-report measures of anxiety in clinical practice improves the precision of therapists' judgment.

Barriers to mental health treatment among individuals with social anxiety disorder and generalized anxiety disorder.

Individuals with social anxiety disorder (SAD) or generalized anxiety disorder (GAD) are at risk for not utilizing mental health treatment. The purpose of this research was to examine barriers to treatment in a sample of adults with clinically significant SAD or GAD. Participants were 226 nontreatment-seeking adults with SAD or GAD who underwent semistructured diagnostic interview and received a clinician assessment of symptom severity as part of a clinical research study. Participants completed a self-report measure of barriers to treatment. Individual and combined associations of demographic and symptom severity variables with number of perceived barriers to treatment were examined. Individuals with GAD or SAD endorsed a similar number of overall barriers to treatment. Shame and stigma were the highest cited barriers followed by logistical and financial barriers. Both groups also endorsed not knowing where to seek treatment at high rates. Individuals with greater symptom severity reported more barriers to treatment. Racial and ethnic minorities reported more barriers to treatment even after controlling for symptom severity. Among individuals with GAD or SAD, increased education and culturally sensitive outreach initiatives are needed to reduce barriers to mental health treatment.

But what will the results be?: Learning to tolerate uncertainty is associated with treatment-produced gains.

The current study examined the association between changes in intolerance of uncertainty (IU) and treatment outcomes for anxious youth. Participants were youth ages 7 to 17 who received cognitive behavioral therapy for anxiety (N = 73). Youth and their primary caregivers completed a diagnostic interview and self- and parent-report measures at pre- and post-treatment, including the Intolerance of Uncertainty Scale for Children (IUS-C/P; Przeworski, 2006), the Coping Questionnaire (CQ-C/P; Kendall, 1994) and the Multidimensional Anxiety Scale for Children (MASC-C/P; March et al., 1997). Hierarchical regression analyses evaluated the role of change in IU (the IUS-C/P) in predicting changes in functional impairment, coping efficacy, and anxiety severity post-treatment, controlling for demographic variables (age and gender), and baseline levels of IU, anxiety severity, functional impairment, and coping efficacy. Results demonstrated that treatment was associated with improvements across child-, parent- and clinician-report, and decreased IU from pre- to post-treatment was associated with (a) decreased functional impairment, (b) increased coping efficacy and (c) decreased anxiety severity. The findings indicate that a greater reduction in IU over treatment is associated with better outcomes in children and adolescents with anxiety across informants, suggesting the possibility that an increased focus on IU during treatment for youth anxiety may improve treatment outcomes. Future research should assess the causality of this relationship.

Targeting separate specific learning parameters underlying cognitive behavioral therapy can improve perceptual judgments of anger.

BACKGROUND AND OBJECTIVES: Anxiety disorders are characterized by biased perceptual judgment. An experimental model using simple verbal instruction to target specific decision parameters that influence perceptual judgment was developed to test if it could influence anger perception, and to examine differences between individuals with social anxiety disorder (SAD) relative to generalized anxiety disorder (GAD) or non-psychiatric controls. METHODS: Anger perception was decomposed into three decision parameters (perceptual similarity of angry vs. not-angry facial expressions, base rate of encountering angry vs. not-angry expressions, payoff for correct vs. incorrect categorization of face stimuli) using a signal detection framework. Participants with SAD (n = 97), GAD (n = 90), and controls (n = 98) were assigned an instruction condition emphasizing one of the three decision parameters. Anger perception pre-vs. post-instruction and its interaction with diagnosis were examined. RESULTS: For all participants, base rate instructions impacted response bias over and above practice effects, supporting the validity of this instructional task-based approach to altering response bias. We failed to find a similarity or payoff instruction effect, nor a diagnosis interaction. LIMITATIONS: Future instructional tasks may need to more closely target core cognitive and perceptual biases in anxiety disorders to identify specific deficits and how to optimally influence them. CONCLUSIONS: This study demonstrates that specific decision parameters underlying perceptual judgment can be experimentally manipulated. Although our study failed to show diagnosis specific effects, it suggests that individual parameter "estimation" deficits may be experimentally isolated and potentially targeted, with the ultimate goal of developing an objective approach to personalized intervention targeting biased perceptual judgments in anxiety disorders.

Defining Treatment Response and Remission in Youth Anxiety: A Signal Detection Analysis With the Multidimensional Anxiety Scale for Children.

OBJECTIVE: To determine the percent reduction cutoffs on the Multidimensional Anxiety Scale for Children (MASC) that optimally predict treatment response and remission in youth with anxiety disorders. METHOD: Youths and their parents completed the MASC-C/P before and after treatment, and the Anxiety Disorders Interview Schedule for DSM-IV-Child and Parent Versions (ADIS-IV-C/P) and the Clinical Global Impression-Improvement Scale (CGI-I) were administered by independent evaluators. Treatment response and remission were defined by post-treatment ratings on the CGI-I and the ADIS-IV-C/P, respectively. Quality receiver operating characteristic methods determined the optimal cutoff on the MASC-P for predicting overall remission (loss of all study entry diagnoses) and optimal percent reductions on the MASC-P for predicting treatment response and remission of separation anxiety, social anxiety, and generalized anxiety. RESULTS: A post-treatment raw score of 42 optimally predicted remission. A reduction of 35% on the total MASC-P predicted treatment response. A reduction of 30% on the Separation Anxiety/Panic subscale of the MASC-P predicted separation anxiety remission. A reduction of 35% on the Social Anxiety subscale of the MASC-P predicted social anxiety remission. The MASC did not evidence a cutoff for remission of generalized anxiety disorder. CONCLUSION: MASC cutoffs can facilitate comparison across studies and guide practice, aiding clinicians in assessing progress and informing treatment plans.

Associations between feelings of social anxiety and emotion perception.

BACKGROUND: Abnormally biased perceptual judgment is a feature of many psychiatric disorders. Thus, individuals with social anxiety disorder are biased to recall or interpret social events negatively. Cognitive behavioral therapy addresses such bias by teaching patients, via verbal instruction, to become aware of and change pathological misjudgment. The present study examined whether targeting verbal instruction to specific decision parameters that influence perceptual judgment may affect changes in anger perception. METHOD: We used a signal detection framework to decompose anger perception into three decision parameters (base rate of encountering anger vs. no-anger, payoff for correct vs. incorrect categorization of face stimuli, and perceptual similarity of angry vs. not-angry facial expressions). We created brief verbal instructions that emphasized each parameter separately. Participants with social anxiety disorder, generalized anxiety disorder, and healthy controls, were assigned to one of the three instruction conditions. We compared anger perception pre-vs. post-instruction. RESULTS: Base rate and payoff instructions affected response bias over and above practice effects, across the three groups. There was no interaction with diagnosis. DISCUSSION: The ability to target specific decision parameters that underlie perceptual judgment suggests that cognitive behavioral therapy might be improved by tailoring it to patients' individual parameter "estimation" deficits.

The effect of mindfulness meditation training on biological acute stress responses in generalized anxiety disorder.

Mindfulness-Based interventions have increased in popularity in psychiatry, but the impact of these treatments on disorder-relevant biomarkers would greatly enhance efficacy and mechanistic evidence. If Generalized Anxiety Disorder (GAD) is successfully treated, relevant biomarkers should change, supporting the impact of treatment and suggesting improved resilience to stress. Seventy adults with GAD were randomized to receive either Mindfulness-Based Stress Reduction (MBSR) or an attention control class; before and after, they underwent the Trier Social Stress Test (TSST). Area-Under-the-Curve (AUC) concentrations were calculated for adrenocorticotropic hormone (ACTH) and pro-inflammatory cytokines. MBSR participants had a significantly greater reduction in ACTH AUC compared to control participants. Similarly, the MBSR group had a greater reduction in inflammatory cytokines' AUC concentrations. We found larger reductions in stress markers for patients with GAD in the MBSR class compared to control; this provides the first combined hormonal and immunological evidence that MBSR may enhance resilience to stress.

Working memory capacity is associated with optimal adaptation of response bias to perceptual sensitivity in emotion perception.

Emotion perception, inferring the emotional state of another person, is a frequent judgment made under perceptual uncertainty (e.g., a scowling facial expression can indicate anger or concentration) and behavioral risk (e.g., incorrect judgment can be costly to the perceiver). Working memory capacity (WMC), the ability to maintain controlled processing in the face of competing demands, is an important component of many decisions. We investigated the association of WMC and anger perception in a task in which "angry" and "not angry" categories comprised overlapping ranges of scowl intensity, and correct and incorrect responses earned and lost points, respectively. Participants attempted to earn as many points as they could; adopting an optimal response bias would maximize decision utility. Participants with higher WMC more optimally tuned their anger perception response bias to accommodate their perceptual sensitivity (their ability to discriminate the categories) than did participants with lower WMC. Other factors that influence response bias (i.e., the relative base rate of angry vs. not angry faces and the decision costs and benefits) were ruled out as contributors to the WMC-bias relationship. Our results suggest that WMC optimizes emotion perception by contributing to perceivers' ability to adjust their response bias to account for their level of perceptual sensitivity, likely an important component of adapting emotion perception to dynamic social interactions and changing circumstances.
