Mindfulness and Posttraumatic Stress Disorder Symptom Severity in Urban African-American High School Students.

Objectives: The aim of the current study was to examine the relations among mindfulness, posttraumatic stress disorder (PTSD) symptom severity, and stressful life events (SLEs) in African-American urban adolescents. Another aim was to examine mindfulness as a moderator of the relation between SLEs and PTSD symptom severity in this population.

Method: Eighty-eight African-American high school students from a low-income urban community completed measures of demographics, PTSD symptom severity, SLEs, and mindfulness.

Rigor and reproducibility for data analysis and design in the behavioral sciences.

The rigor and reproducibility of science methods depends heavily on the appropriate use of statistical methods to answer research questions and make meaningful and accurate inferences based on data. The increasing analytic complexity and valuation of novel statistical and methodological approaches to data place greater emphasis on statistical review. We will outline the controversies within statistical sciences that threaten rigor and reproducibility of research published in the behavioral sciences and discuss ongoing approaches to generate reliable and valid inferences from data.

Psychometric properties of the Child and Adolescent Mindfulness Measure (CAMM) in racial minority adolescents from low-income environments.

No study has yet assessed the psychometric properties of scores from any mindfulness measure in racial minority adolescents from low-income environments. The present study examined the reliability and validity of Child and Adolescent Mindfulness Measure (CAMM) scores in a nonclinical sample of late adolescents ( = 92) from low-income neighborhoods who predominantly identified as African American. Findings confirmed a one-factor structure for responses to the 10 CAMM items as well as adequate internal consistency (Cronbach's α = .

Psychometric properties of the Generalized Anxiety Disorder Questionnaire - IV (GAD-Q-IV) in postpartum mothers.

Generalized anxiety disorder (GAD) is a mental disorder of which the main feature is persistent and impairing worry. GAD symptoms are common for women during the postpartum period and GAD prevalence rates have been reported as higher in postpartum mothers than in the general population. Currently, little psychometric evidence exists for a screening measure to detect the possible presence of diagnosable GAD for postpartum women.

Maternal postnatal depression and anxiety and their association with child emotional negativity and behavior problems at two years.

Postnatal maternal depression is associated with poorer child emotional and behavioral functioning, but it is unclear whether this occurs following brief episodes or only with persistent depression. Little research has examined the relation between postnatal anxiety and child outcomes. The present study examined the role of postnatal major depressive disorder (MDD) and generalized anxiety disorder (GAD) symptom chronicity on children's emotional and behavioral functioning at 24 months.

A comparison and integration of structural models of depression and anxiety in a clinical sample: Support for and validation of the tri-level model.

Prominent structural models of depression and anxiety arise from 2 traditions: (a) the tripartite/integrative hierarchical model based on symptom dimensions, and (b) the fear/anxious-misery model based on diagnostic comorbidity data. The tri-level model of depression and anxiety was developed to synthesize these structural models, postulating that narrow (disorder-specific), intermediate (fear and anxious-misery), and broad (general distress) structural factors are needed to most fully account for covariation among these symptoms. Although this model has received preliminary support (Prenoveau et al.

Item analysis of the Leeds Dependence Questionnaire in community treatment centers.

The present study extends the item-level psychometric information of the Leeds Dependence Questionnaire (LDQ; Raistrick et al., 1994) that has been purported to measure psychological dependence and the International Statistical Classification of Diseases and Related Health Problems-10th edition substance dependence criteria. Prior research on the LDQ has not established item-level properties or the degree of differential item functioning (DIF) by gender and substance type.

Interaction of CD38 Variant and Chronic Interpersonal Stress Prospectively Predicts Social Anxiety and Depression Symptoms Over Six Years.

Variation in the CD38 gene, which regulates secretion of the neuropeptide oxytocin, has been associated with several social phenotypes. Specifically, rs3796863 A allele carriers have demonstrated increased social sensitivity. In 400 older adolescents, we used trait-state-occasion modeling to investigate how rs3796863 genotype, baseline ratings of chronic interpersonal stress, and their gene-environment (GxE) interaction predicted trait social anxiety and depression symptoms over six years.

Response to Comment on "Estimating the reproducibility of psychological science".

Gilbert et al. conclude that evidence from the Open Science Collaboration's Reproducibility Project: Psychology indicates high reproducibility, given the study methodology. Their very optimistic assessment is limited by statistical misconceptions and by causal inferences from selectively interpreted, correlational data.

Language can be viewed as a complex set of cues that shape people's mental representations of situations. For example, people think of behavior described using imperfective aspect (i.e.

Prospective associations of low positive emotionality with first onsets of depressive and anxiety disorders: Results from a 10-wave latent trait-state modeling study.

Unipolar depressive disorders and anxiety disorders co-occur at high rates and can be difficult to distinguish from one another. Cross-sectional evidence has demonstrated that whereas all these disorders are characterized by high negative emotion, low positive emotion shows specificity in its associations with depressive disorders, social anxiety disorder, and possibly generalized anxiety disorder. However, it remains unknown whether low positive emotionality, a personality trait characterized by the tendency to experience low positive emotion over time, prospectively marks risk for the initial development of these disorders.

Measuring Positive Emotion With the Mood and Anxiety Symptom Questionnaire: Psychometric Properties of the Anhedonic Depression Scale.

Low positive emotion distinguishes depression from most types of anxiety. Formative work in this area employed the Anhedonic Depression scale from the Mood and Anxiety Symptom Questionnaire (MASQ-AD), and the MASQ-AD has since become a popular measure of positive emotion, often used independently of the full MASQ. However, two key assumptions about the MASQ-AD-that it should be represented by a total scale score, and that it measures time-variant experiences-have not been adequately tested.

Post-extinction conditional stimulus valence predicts reinstatement fear: relevance for long-term outcomes of exposure therapy.

Exposure therapy for anxiety disorders is translated from fear conditioning and extinction. While exposure therapy is effective in treating anxiety, fear sometimes returns after exposure. One pathway for return of fear is reinstatement: unsignaled unconditional stimuli following completion of extinction.

Human fear conditioning and extinction: timing is everything…or is it?

A differential fear conditioning paradigm was used with 107 healthy undergraduate participants to evaluate the effect of conditioned stimulus (CS) temporal properties on fear acquisition and extinction. Two minute duration CSs were used for Day 1 fear acquisition. Participants were randomized to receive either 1, 2, or 4min CS durations during Day 2 extinction.

Are anxiety and depression just as stable as personality during late adolescence? Results from a three-year longitudinal latent variable study.

Although considerable evidence shows that affective symptoms and personality traits demonstrate moderate to high relative stabilities during adolescence and early adulthood, there has been little work done to examine differential stability among these constructs or to study the manner in which the stability of these constructs is expressed. The present study used a three-year longitudinal design in an adolescent/young adult sample to examine the stability of depression symptoms, social phobia symptoms, specific phobia symptoms, neuroticism, and extraversion. When considering one-, two-, and three-year durations, anxiety and personality stabilities were generally similar and typically greater than the stability of depression.

Testing a hierarchical model of anxiety and depression in adolescents: a tri-level model.

The present study examined the structural relationships among anxiety and depressive symptoms in a sample of high school juniors. The best-fitting structural representation was a tri-level hierarchical arrangement with a broad general factor (general distress), two factors of intermediate breadth (anxious-misery and fears), and five conceptually meaningful, narrow group factors. In accord with the integrative hierarchical model of anxiety and depression, the results supported a structure with a symptom factor central to major depression, and other symptom factors specific to particular anxiety disorders.

Evaluating the invariance and validity of the structure of dysfunctional attitudes in an adolescent population.

Form A of the Dysfunctional Attitude Scale (DAS-A), a self-report measure of depressive beliefs, is widely used to test Beck's cognitive model of depression. The present study is the first to evaluate the DAS-A factor structure in an adolescent population of 542 high school juniors and the first to examine a hierarchical model. Findings support the existence of a hierarchical structure consisting of two conceptually meaningful group factors (Dysfunctional Attitudes About Achievement and Dysfunctional Attitudes About Needing Approval), a method factor consisting of reverse-worded items, and a general factor, which accounts for 65% of the variance in total scores.

Interoceptive fear conditioning as a learning model of panic disorder: an experimental evaluation using 20% CO(2)-enriched air in a non-clinical sample.

Despite the role afforded interoceptive fear conditioning in etiologic accounts of panic disorder, there are no good experimental demonstrations of such learning in humans. The aim of the present study was to evaluate the interoceptive conditioning account using 20% carbon dioxide (CO(2))-enriched air as an interoceptive conditioned stimulus (CS) (i.e.

Repeated exposure to 20% CO2 challenge and risk for developing panic attacks: a controlled 6- and 12-month follow-up in a nonclinical sample.

Among ethical concerns associated with biological challenge procedures is the risk of potentiating panic attacks in otherwise healthy persons who have no history of panic. The aim of the present study was to determine if repeated exposure to 20% CO2 challenge increases the risk of developing panic attacks in a nonclinical sample. One hundred and fifty-five (39.
