An Open-Label Study of a Wearable Device Targeting ADHD, Executive Function, and Academic Performance.

Objective: This was an open-label pilot study to test the feasibility and preliminary efficacy of a wearable digital intervention developed to improve on-task behavior. This was an exploratory study to test for specificity of response on parent- and teacher-reported symptom outcomes in attention and hyperactive/impulsive symptoms, as well as domains of functional impairment, including school behavior and learning and executive function.

Method: Participants included 38 children aged 8-12 years with a parent-reported past diagnosis of ADHD.

Consistency checks to improve measurement with the Positive and Negative Syndrome Scale (PANSS).

International Society for CNS Clinical Trials and Methodology convened an expert working-group that assembled consistency/inconsistency flags for the Positive and Negative Syndrome Scale (PANSS). Twenty-four flags were identified and divided based on extent to which they represent error (Possibly, Probably, Very probably or definitely). The flags were applied to assessments derived from the NEWMEDS data repository and the CATIE clinical trial data.

The Effect of Response Bias on the Personality Inventory for DSM-5 (PID-5).

Valid self-report assessment of psychopathology relies on accurate and credible responses to test questions. There are some individuals who, in certain assessment contexts, cannot or choose not to answer in a manner typically representative of their traits or symptoms. This is referred to, most broadly, as test response bias.

Associations between DSM-5 section III personality traits and the Minnesota Multiphasic Personality Inventory 2-Restructured Form (MMPI-2-RF) scales in a psychiatric patient sample.

Our aim in the current study was to evaluate the convergence between Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) Section III dimensional personality traits, as operationalized via the Personality Inventory for DSM-5 (PID-5), and Minnesota Multiphasic Personality Inventory 2-Restructured Form (MMPI-2-RF) scale scores in a psychiatric patient sample. We used a sample of 346 (171 men, 175 women) patients who were recruited through a university-affiliated psychiatric facility in Toronto, Canada. We estimated zero-order correlations between the PID-5 and MMPI-2-RF substantive scale scores, as well as a series of exploratory structural equation modeling (ESEM) analyses to examine how these scales converged in multivariate latent space.

The internet administration version of the 20-item Toronto alexithymia scale.

Researchers are increasingly administering tests developed and validated in paper format via the Internet. Yet, the equivalence between paper and Internet concerning administration of tests is not typically demonstrated. We evaluated the reliability, factorial and external validity, and measurement equivalency of the Internet version of the 20-item Toronto Alexithymia Scale (TAS-20; Bagby, Parker, & Taylor, 1994; Bagby, Taylor, & Parker, 1994; Lumley et al.

Exploring the hierarchical structure of the MMPI-2-RF Personality Psychopathology Five in psychiatric patient and university student samples.

In this study our goal was to examine the hierarchical structure of personality pathology as conceptualized by Harkness and McNulty's (1994) Personality Psychopathology Five (PSY-5) model, as recently operationalized by the MMPI-2-RF (Ben-Porath & Tellegen, 2011) PSY-5r scales. We used Goldberg's (2006) "bass-ackwards" method to obtain factor structure using PSY-5r item data, successively extracting from 1 to 5 factors in a sample of psychiatric patients (n = 1,000) and a sample of university undergraduate students (n = 1,331). Participants from these samples had completed either the MMPI-2 or the MMPI-2-RF.

The psychometric properties of the personality inventory for DSM-5 in an APA DSM-5 field trial sample.

Section 3 of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) includes a hybrid model of personality pathology, in which dimensional personality traits are used to derive one of seven categorical personality disorder diagnoses. The Personality Inventory for DSM-5 (PID-5) was developed by the DSM-5 Personality and Personality Disorders workgroup and their consultants to produce a freely available instrument to assess the personality traits within this new system. To date, the psychometric properties of the PID-5 have been evaluated primarily in undergraduate student and community adult samples.

Evaluating the interpersonal content of the MMPI-2-RF Interpersonal Scales.

Convergence between the MMPI-2 Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008) interpersonal scales and 2 interpersonal circumplex (IPC) measures was examined. University students (N = 405) completed the MMPI-2 and 2 IPC measures, the Interpersonal Adjectives Scales Revised Big Five Version (IASR-B5; Trapnell & Wiggins, 1990) and the Inventory of Interpersonal Problems Circumplex (IIP-C; Horowitz, Alden, Wiggins, & Pincus, 2000). Internal consistency was adequate for 3 of the 6 scales investigated.

The Pain and Sleep Questionnaire three-item index (PSQ-3): a reliable and valid measure of the impact of pain on sleep in chronic nonmalignant pain of various etiologies.

Background: Sleep disturbance is among the more common complaints reported by chronic pain patients. Because pain-related sleep disturbance may serve as a marker for the assessment of responses to treatment for chronic pain, inclusion of a measure designed to assess the impact of pain on sleep in clinical trial protocols is important, if not necessary. Measures typically used for this purpose lack scales specifically designed for the assessment of the impact of pain on sleep or are based on a single item.

Examination of the trait facets of the five-factor model in discriminating specific mood and anxiety disorders.

Structural models of the mood and anxiety disorders postulate that each disorder has a shared component that can account for comorbidity and its own unique component that distinguishes it from others. The principal aim of the current study was to determine the extent to which the 30 facets of the Five-Factor Model (FFM), as measured by the Revised NEO Personality Inventory (NEO PI-R), contribute to the identification of the unique component in mood and anxiety disorders in treatment-seeking clinical samples. Participants (N=610) were psychiatric outpatients with principal DSM-IV diagnoses (Diagnostic and Statistical Manual-IV; American Psychiatric Association, 1994) diagnoses of major depressive disorder (MDD), post-traumatic stress disorder (PTSD), generalized social phobia (GSP), panic disorder with/without agoraphobia (PD; PD/A) or obsessive-compulsive disorder (OCD).

Where is multidimensional perfectionism in DSM-5? A question posed to the DSM-5 personality and personality disorders work group.

A radical reworking of Axis II has been proposed for the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders whereby personality disorder categories will be replaced by a trait dimensional model of personality pathology. Perfectionism is specified as a lower order facet of Compulsivity within this proposed model. This marginalization of the perfectionism construct is inconsistent with the empirical literature that suggests that perfectionism is an important dimension of maladaptive personality in its own right, complete with its own set of more specific lower order facets.

Diagnostic construct validity of MMPI-2 Restructured Form (MMPI-2-RF) scale scores.

In the current investigation, the authors examined the diagnostic construct validity of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) in a patient sample. All participants were diagnosed via the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I/P). The data set used in this study was composed of 544 patients--67 with bipolar disorder, 407 with major depressive disorder, and 70 with schizophrenia.

Assessing excessive reassurance seeking in the anxiety disorders.

Reassurance seeking has long been hypothesized to be a key factor in the maintenance of anxiety within contemporary cognitive-behavioral approaches to the conceptualization and treatment of anxiety disorders. However, empirical studies have lagged due to the absence of a reliable and valid measure of reassurance seeking. The present study sought to develop and examine the psychometric properties of a theoretically derived measure of reassurance seeking in treatment-seeking participants with DSM-IV-TR (American Psychiatric Association, 2000) social phobia (n=116), generalized anxiety disorder (n=75), panic disorder with or without agoraphobia (n=50), and obsessive compulsive disorder (n=42).

Where is the Personality in Personality Disorder Assessment? A Comparison Across Four Sets of Personality Disorder Scales.

The present research examined the amount and kind of personality measured within four sets of personality disorder (PD) scales. Three samples of undergraduate students (Ns = 326, 537, and 617) completed at least one PD measure and a combined interpersonal circumplex model (ICM) and five-factor model (FFM) measure. The FFM dimensions were found to account for between 5% to 57% of the variance in personality disorder symptomatology depending on the PD examined and the PD measure employed.
