Factoring The Personal Profile System For Construct Validity: Three Analyses Under Different Standardization Assumptions, Thomas G. Henkel, James Noel Wilmoth

Tom G. Henkel

Three types of data were factor analyzed using principal components extractions with orthogonal and oblique rotations to test publisher claims for construct validity of the Personal Profile System (PPS). Behavioral descriptor data from 1,045 senior non-commissioned Air Force officers were factored as raw data, mean corrected data, and standardized z-scores (correlations). The most efficacious solution was produced with standardized z-scores generating four factors accounting for 86% of the total variance. The measure of sampling adequacy for every descriptor exceeded 0.922. The first factor was general with approximately equal loadings on each of the dominance, influencing, steadiness, and compliance dimensions. The …

Cognitive Triad Inventory (Cti) : Psychometric Properties And Factor Structure Of The German Translation., Patrick Pössel

Patrick Pössel

A central component of Beck, A. T., Rush, J., & Shaw, B. F. [(1979). Cognitive therapy of depression. New York: Guilford Press] cognitive theory of depression is the cognitive triad (negative view of self, world, and future) measurable with the Cognitive Triad Inventory (CTI). This study examined the psychometric properties and factor structure of the German CTI in a sample of 796 German volunteers. The study provides evidence for the reliability and validity of the German CTI and of independent positive and negative elements of the cognitive triad. Furthermore, results emphasize methodological above conceptual problems in Beck et al.'s (1979) …

Respondent Self-Focus And The Internal Consistency Of The Motivational Style Profile, Kenneth M. Cramer, Kathryn Lafreniere, Phillip A. Ianni

Kathryn Lafreniere

One of the underlying tenets of both personality and social psychological theory assumes that questionnaire respondents have access to their thoughts and feelings. The same tenet underlies the various reversal theory states (e.g., telic/paratelic, negativism/conformity, autic mastery /sympathy, alloic mastery/sympathy), so that individuals who are more internally focused should have better access to their internal states and have higher internal consistency ratings across all measures. To evaluate this tenet, 620 participants recruited from a community sample completed a questionnaire that included the Motivational Style Profile and three self-focus measures: self-monitoring, identity formation, and private self-consciousness. Participants were divided (by median …

Cross-Cultural Adaptation, Validation And Reliability Of The Brazilian Version Of The Richmond Compulsive Buying Scale, Priscilla Leite, Bernard Range, Monika Kukar-Kinney, Nancy Ridgway, Kent Monroe, Rodolfo Ribas Jr., J. Landeira-Fernandez, Antonio Egidio Nardi, Adriana Silva

Nancy Ridgway

Objective: To present the process of transcultural adaptation of the Richmond Compulsive Buying Scale to Brazilian Portuguese. Methods: For the semantic adaptation step, the scale was translated to Portuguese and then back-translated to English by two professional translators and one psychologist, without any communication between them. The scale was then applied to 20 participants from the general population for language adjustments. For the construct validation step, an exploratory factor analysis was performed, using the scree plot test, principal component analysis for factor extraction, and Varimax rotation. For convergent validity, the correlation matrix was analyzed through Pearson’s coefficient. Results: The scale …

An Alternative To Cronbach's Alpha: An L-Moment-Based Measure Of Internal-Consistency Reliablilty, Todd C. Headrick, Yanyan Sheng

Todd Christopher Headrick

Data sets in the social and behavioral sciences are often small or heavy-tailed. Previous studies have demonstrated that small samples or leptokurtic distributions adversely affect the performance of Cronbach’s coefficient alpha. To address these concerns, we propose an alternative estimator of reliability based on L-comoments. The empirical results of this study demonstrate that when sample sizes are small and distributions are heavy-tailed that the proposed coefficient L-alpha has substantial advantages over the conventional Cronbach estimator of reliability in terms of relative bias and relative standard error.

A Positive Trait Item Response Model, Joseph F. Lucke

Joseph Lucke

All current models from item response theory (IRT) assume the latent trait follows a standard normal distribution. While this assumption is appropriate for traits such as ability or attitude, it creates both conceptual and technical problems traits such as addiction (alcohol, drugs, gambling). The distribution of an addiction trait is better assumed to be anchored at zero (no addiction) and positively skewed. A small change to the usual IRT model yields a class of positive-trait item response models (PTIRMs). I discuss PTIRMs and present one model in detail, including item characteristic curves and item information curves. I present an example …

Positive Trait Item Response Models, Joseph F. Lucke

Joseph Lucke

A new item response model is proposed for which the trait is positive. Three such models, the loglogistic, the log-normal, and the Weibull, are presented along with their item information curves. The data of seven addiction items from the DSM-IV from a study on alcohol addiction is analyzed by these three models using Bayesian Markov chain Monte Carlo methods. The item characteristic curves and item information curves are presented for all three models. The person scores for four item response patterns are presented for the log-logistic model.

Predicting Breast-Feeding Attrition: Adapting The Breast-Feeding Attrition Prediction Tool, Elizabeth Reifsnider, Sarah L. Gill, Joseph F. Lucke, Angela R. Mann

Joseph Lucke

CONTEXT: Current breast-feeding rates fall short of the recommendations set forth in Health People 2010. The Breast-feeding Attrition Prediction Tool (BAPT), administered in the postpartum period, has been useful in predicting breast-feeding attrition. However, assessing a woman's intention to breast-feed prior to birth would identify women at risk for breast-feeding attrition.

PURPOSE: The purpose of this study was to describe a revised BAPT, administered antepartally that measures intention to breast-feed.

METHODS: The BAPT, comprising 94 items on a 6-point Likert-type scale, was translated into Spanish and back-translated for accuracy. The BAPT was then revised by reducing the number of items …

"Rassling The Hog": The Influence Of Correlated Item Error On Internal Consistency, Classical Reliability, And Congeneric Reliability, Joseph F. Lucke

Joseph Lucke

The properties of internal consistency ($\alpha$), classical reliability ($\rho$), and congeneric reliability ($\omega$) for a composite test with correlated item error were analytically investigated. Possible sources of correlated item error are contextual effects, item bundles, and item models that ignore additional attributes or higher-order attributes. The relation between reliability and internal consistency is determined by the deviance from true-score equivalence. Reliability (classical or congeneric) is internal consistency plus the relative deviance from true-score equivalence. The influence of correlated item error on $\alpha$, $\rho$, and $\omega$ is conveyed strictly through the total item error covariance. As the total item error covariance …

The $\Alpha$ And The $\Omega$ Of Congeneric Test Theory: An Extension Of Reliability And Internal Consistency To Heterogeneous Tests, Joseph F. Lucke

Joseph Lucke

Psychometric theory focuses primarily on tests that are homogeneous, that measure only one attribute of a psychosocial entity. However, the complexity of psychosocial behavior often requires tests that are heterogeneous, that measure more than one attribute. In this presentation, reliability and internal consistency are extended to heterogeneous tests under the rubric of congeneric test theory. The extensions show that reliability and internal consistency have very similar properties. Reliability and internal consistency are shown to be unique up to a linear transformation. Whereas internal consistency is a lower bound to reliability in the homogeneous case, it is a strict lower bound …
