Interpretation Bias and Anticipated Distress in the Face of Ambiguity: Predictors of Change in Cognitive Behavioral Therapy for Youth Anxiety.

This study examined associations among children's anxiety, interpretation bias, and anticipated distress before and after cognitive behavioral therapy (CBT) and investigated baseline levels of interpretation bias and anticipated distress as well as changes in these cognitive biases following treatment as predictors of treatment outcome. Clinically anxious youth (N = 39) were treated with brief CBT augmented with a smartphone app. Children completed measures assessing their anxiety, interpretation bias, and anticipated distress at baseline, post-treatment, and 2-month follow-up. Children's anxiety, interpretation bias, and anticipated distress significantly decreased following treatment. Anticipated distress was associated with higher anxiety at all time points; however, interpretation bias was not significantly associated with anxiety before or after treatment. Reductions in anticipated distress following treatment predicted concurrent and prospective reductions in anxiety. Reduced anticipated distress following treatment may contribute to enhanced treatment outcomes and may be more strongly related to the maintenance of youth anxiety than interpretation bias.

A Brief Measure of Positive and Negative Interpretation Biases: Development and Validation of the Ambiguous Social Scenarios Questionnaire.

Positive and negative interpretation biases have been conceptualized as distinct constructs related to anxiety and social anxiety, but the field lacks psychometrically sound self-report measures to assess positive and negative interpretations of social ambiguity. This study examined the psychometric properties of the Ambiguous Social Scenarios Questionnaire (ASSQ) in two samples of 2,188 and 454 undergraduates with varying levels of anxiety. Results supported a bifactor model with a general interpretation bias factor and specific factors assessing positive and negative interpretation biases. The ASSQ demonstrated measurement invariance across genders and levels of social anxiety, as well as convergent and incremental validity with two existing measures of interpretation bias. It also demonstrated concurrent validity with attentional control, intolerance of uncertainty, total anxiety, and social anxiety and discriminant validity with emotional awareness. Findings support the ASSQ as a brief, valid, and reliable measure of positive and negative interpretation biases toward ambiguous social situations.

An Integrative Model of Youth Anxiety: Cognitive-Affective Processes and Parenting in Developmental Context.

Multiple theoretical frameworks have been proposed to provide a more comprehensive picture of the risk factors that influence anxiety-related developmental trajectories. Nonetheless, there remains a need for an integrative model that outlines: (1) which risk factors may be most pertinent at different points in development, and (2) how parenting may maintain, exacerbate, or attenuate an affective style that is characterized by high negative emotional reactivity to unfamiliar, uncertain, and threatening situations. A developmentally informed, integrative model has the potential to guide treatment development and delivery, which is critical to reducing the public health burden associated with these disorders. This paper outlines a model integrating research on many well-established risk mechanisms for anxiety disorders, focusing on (1) the developmental progression from emotional reactivity constructs early in life to those involving higher-level cognitive processes later in youth, and (2) potential pathways by which parenting may impact the stability of youth's cognitive-affective responses to threat-relevant information across development.

Applying the DSM-5 Alternative Model of Personality Disorders and the Shedler-Westen Assessment Procedure to the Classic Case of "Madeline G.": Novice and Expert Rater Convergences and Divergence.

Prior research supports the learnability of the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition Alternative Model of Personality Disorders (AMPD). However, researchers have yet to compare novice ratings on the AMPD's Level of Personality Functioning Scale and the 25 pathological personality traits with expert ratings. Furthermore, the AMPD has yet to be examined with the idiographic Shedler-Westen Assessment Procedure (SWAP). We compared the aggregated AMPD clinical profile of a group of psychology doctoral students who learned the AMPD to high levels of reliability to that of an expert rater using the crucible of the classical case of "Madeline G." Examination of AMPD and SWAP ratings of "Madeline G." revealed excellent overall concordance but suggests that novice raters tend to perceive lower levels of personality impairment.

Effects of Microglial Cytokines on Alzheimer's Disease-Related Phenomena.

Recent association studies indicate several genes highly expressed by microglia influence Alzheimer's disease (AD) risk, which suggests microglial function contributes to this disease. Here, we evaluated how one component of microglial function, cytokine release, affects AD-related phenomena. First, we used a 3-hour lipopolysaccharide (LPS) treatment to activate mouse BV2 microglial cells. Next, we removed the LPS-containing medium, added LPS-free medium, and after 6 hours collected the medium conditioned by the activated BV2 microglial cells. We then exposed human neuronal SH-SY5Y cells to the conditioned medium for 24 hours. At the end of the 24-hour exposure, we assessed amyloid-ß protein precursor (AßPP), tau, apolipoprotein E (ApoE), and lipid status. The amount of AßPP was unaffected, although a slight decrease in soluble AßPPα suggested a subtle reduction in AßPP non-amyloidogenic processing occurred. Tau mRNA increased, but total and phosphorylated tau levels were unchanged. ApoE mRNA increased, while ApoE protein levels were lower. Per cell lipid droplet number decreased and lipid oxidation increased. These results show cytokine release by activated microglial cells can influence specific AD-relevant physiologies and pathologies.

Challenging fat talk: An experimental investigation of reactions to body disparaging conversations.

Although "fat talk" is associated with increased eating disorder risk, the predictors of fat talk engagement and viable alternatives to these pervasive conversations remain unclear. The current experiment examined responses to fat talk versus feminist-oriented challenging fat talk scenarios. Undergraduate women (N=283) completed baseline questionnaires assessing body dissatisfaction, fat talk engagement, and positive impression management. One week later, they were randomized to view one of the two scenarios, followed by assessment of mood, fat talk engagement, social acceptability, and social likeability. Results indicated that the challenging fat talk vignette (versus the fat talk vignette) yielded less negative affect and fat talk and was perceived as more socially attractive with a more likeable target character. Baseline body dissatisfaction, baseline fat talk tendencies, and momentary negative affect predicted post-exposure fat talk engagement. Current findings highlight possibilities for implementing feminist language and psychoeducation in fat talk prevention efforts.
