Initial Validation of a Computerized Adaptive Test for Substance Use Disorder Identification in Adolescents
PURPOSE: Computerized adaptive tests (CATs) are highly efficient assessment tools that couple low patient and clinician time burden with high diagnostic accuracy. A CAT for substance use disorders (CAT-SUD-E) has been validated in adult populations but has yet to be tested in adolescents. The purpose of this study was to perform initial evaluation of the K-CAT-SUD-E (i.e., Kiddy-CAT-SUD-E) in an adolescent sample compared to a gold-standard diagn…
Perspectives from the Autism Community on the Potential Utility of a Novel Measure of Suicide Risk and Mental Health Symptoms for Autistic Youth
Use of central nervous system drugs in combination with selective serotonin reuptake inhibitor treatment
Several of the detected signals for reduced risk correspond to drugs where there is previous evidence of benefit for antidepressant augmentation (e.g., olanzapine, quetiapine, lithium, buspirone, and mirtazapine). Novel signals of reduced suicidal behavior risk, including for lamotrigine, valproic acid, risperidone, and melatonin, warrant further investigation
Wingman-Connect Program increases social integration for Air Force personnel at elevated suicide risk
U.S. military suicides are increasing and disrupted relationships frequently precede them. Group-level interventions are needed that reduce future suicide vulnerability among healthy members and also ameliorate risk among those already suicidal. We examined whether our Wingman-Connect Program (W-CP) strengthened Air Force relationship networks and socially integrated at-risk members. Air Force personnel classes in training were randomized to W-CP…
Computerized-Adaptive vs. Traditional Ratings of Depression and Suicidal Thoughts
There is a public health need for improved suicide risk assessment tools. This pilot methodology study compared the assay sensitivity of computerized adaptive tests (CAT) of depression and suicidal ideation vs. traditional ratings in a randomized trial subgroup. The last 20 persons to enroll in a published ketamine trial in suicidal depression were studied. This subgroup received traditional and CAT ratings at baseline, 24 h post-infusion and fol…
Are Evidence-based Practices Associated With Effective Prevention of Hospital-acquired Pressure Ulcers in US Academic Medical Centers
BACKGROUND: In 2008, the Centers for Medicare and Medicaid Services (CMS) established nonpayment policies resulting from costliness of hospital-acquired pressure ulcers (HAPUs) to hospitals. This prompted hospitals to adopt quality improvement (QI) interventions that increase use of evidence-based practices (EBPs) for HAPU prevention. OBJECTIVE: To evaluate the longitudinal impact of CMS policy and QI adoption on HAPU rates. MATERIALS AND METHODS…
The Social Context of Urban Classrooms
Classrooms are unique and complex work settings in which teachers and students both participate in and contribute to classroom processes. This article describes the measurement phase of a study that examined the social ecology of urban classrooms. Informed by the dimensions and items of an established measure of organizational climate, we designed the Student Climate Survey ( n = 53 items) to assess student psychological climate in third through …

Is the Rate of Suicide Among Veterans Elevated
The authors reflect on the suicide rate among U.S. military veterans. They suggest that there are conflicting and possibly biased research results regarding the suicide rate of U.S. military veterans. They argue that additional research needs to be conducted to find verified data on the risk of suicide among U.S. veterans

Contextual Predictors of Mental Health Service Use Among Children Opento Child Welfare
BACKGROUND: Children involved with child welfare systems are at high risk for emotional and behavioral problems. Many children with identified mental health problems do not receive care, especially ethnic/minority children. OBJECTIVE: To examine how patterns of specialty mental health service use among children involved with child welfare vary as a function of the degree of coordination between local child welfare and mental health agencies. DESI…
Application of random-effects pattern-mixture models for missing data in longitudinal studies.
Random-effects regression models have become increasingly popular for analysis of longitudinal data. A key advantage of the random-effects approach is that it can be applied when subjects are not measured at the same number of timepoints. In this article we describe use of random-effects pattern-mixture models to further handle and describe the influence of missing data in longitudinal studies. For this approach, subjects are first divided into g…
A Random-Effects Ordinal Regression Model for Multilevel Analysis
A random-effects ordinal regression model is proposed for analysis of clustered or longitudinal ordinal response data. This model is developed for both the probit and logistic response functions. The threshold concept is used, in which it is assumed that the observed ordered category is determined by the value of a latent unobservable continuous response that follows a linear regression model incorporating random effects. A maximum marginal likel…

Full-Information Item Bi-Factor Analysis
A plausible s -factor solution for many types of psychological and educational tests is one that exhibits a general factor and s − 1 group or method related factors. The bi-factor solution results from the constraint that each item has a nonzero loading on the primary dimension and at most one of the s − 1 group factors. This paper derives a bi-factor item-response model for binary response data. In marginal maximum likelihood estimation of item …
Full-Information Item Factor Analysis
A method of item factor analysis based on Thur stone's multiple-factor model and implemented by marginal maximum likelihood estimation and the EM algorithm is described. Statistical significance of suc cessive factors added to the model is tested by the likelihood ratio criterion. Provisions for effects of guessing on multiple-choice items, and for omitted and not-reached items, are included. Bayes constraints on the factor loadings are found to …
