Guessing behavior is an important topic with regard to assessing proficiency on multiple choice tests, particularly for examinees at lower levels of proficiency due to greater the potential for systematic error or bias which that inflates observed test scores. Methods that incorporate a correction for guessing on high-stakes tests generally rely on a scoring model that aims to minimize the potential benefit of guessing. In some cases, a formula score based on classical test theory (CTT) is applied with the intention of eliminating the influence of guessing from the number-right score (e.g., Holzinger, 1924). However, since its inception, significant controversy has surrounded the use and consequences associated with classical methods of correcting for guessing. More recently, item response theory (IRT) has been used to conceptualize and describe the effects of guessing. Yet CTT remains a dominant aspect of many assessment programs, and IRT models are rarely used for estimating proficiency with MC items – where guessing is most likely to exert an influence. Although there has been tremendous growth in the research of formal modeling based on IRT with respect to guessing, none of these IRT approaches have had widespread application. This dissertation provides a conceptual analysis of how the ―correction for guessing works within the framework of a 3PL model, and two new guessing correction formulas based on IRT are derived for improving observed score estimates. To demonstrate the utility of the new formula scores, they are applied as conditioning variable in two different approaches to DIF: the Mantel-Haenszel and logistic regression procedures. Two IRT formula scores were developed using Taylor approximations. Each of these formula scores requires the use of sample statistics in lieu of IRT parameters for estimating corrected true scores, and these statistics were obtained in two different ways that are referred to as the pseudo-Bayes and conditional probability methods. It is shown that the IRT formula scores adjust the number-correct score based on both the proficiency of an examinees and the examinee‘s pattern of responses across items. In two different simulation studies, the classical formula score performed better in terms of bias statistics, but the IRT formula scores had notable improvement in bias and r2 statistics compared to the number-correct score. The advantage of the IRT formula scores accounted for about 10% more of the variance in corrected true scores in the first quartile. Results also suggested that not much information lost due to the use of Taylor approximation. The pseudo-Bayes and conditional probabilities methods also resulted in little information loss. When applied to DIF analyses, the IRT formula scores had lower bias in both the log-odds ratios and type 1 error rates compared to the number-corrected score. Overall, the IRT formula scores decreased bias in the log-odds ratio by about 6% and in the type 1 error rate by about 10%.

▼ Item response theory (IRT) is a broad modeling framework that makes precise predictions about item response behavior given individuals’ locations on a latent (unobserved) variable. If the item-trait regressions, also known as item response functions (IRFs), are monotonically increasing and if assumptions about unidimensionality and local independence are satisfied, then examinees can be ordered uniquely on the latent trait. Scales that satisfy these three assumptions can be transformed monotonically without altering scale properties—that is, they define an ordinal-level scale (Stevens, 1946). When fitting an IRT model, however, the scale of the latent variable—that is, its location and interval spacing—must be identified by introducing extra assumptions. In practice, the scale is identified by specifying either the parametric form of the IRF (parametric IRT) or the distribution of the latent trait (nonparametric IRT). Filtered monotonic polynomial IRT (FMP) has been proposed as a type of nonparametric IRT method (Liang & Browne, 2015), but shares important properties with parametric methods. In this dissertation, it is demonstrated that any IRF defined within the FMP framework can be re-expressed as another FMP IRF by taking linear or nonlinear transformations of the latent trait. A general form for these transformations is presented in terms of matrix algebra. Finally, I propose a composite FMP IRT model in which nonlinear transformations of the latent trait are modeled explicitly by a monotonic composite function.I argue that the composite model offers many advantages over existing methods. First, the composite FMP model narrows the methodological gap between para- metric and nonparametric item response models, allowing for item banking and adaptive testing within a flexible modeling framework. Second, this composite model suggests a sequential NIRT curve-fitting method that allows users to explore both alternate (e.g., non-normal) latent densities and flexible IRF shapes. Finally, the composite FMP model allows users to explore and employ alternate scalings of the latent trait without sacrificing the methodological advantages of parametric models.

▼ In the past several decades, Computerized Adaptive Testing (CAT) has received much attention in educational and psychological research due to the efficiency in achieving the goal of assessment, whether it is to estimate the latent trait of test takers with high precision or to accurately classify them into one of several latent classes. In the latter case, the adaptive nature of CAT is used in educational testing to make inferences about the location of examinees' latent ability relative to one or more pre-specified cut-off points along the ability continuum. When there is only one cut-off point and two proficiency groups, this type of CAT is commonly referred to as Adaptive Mastery Testing (AMT). A well-known approach in AMT is to combine the Sequential Probability Ratio Test (SPRT) stopping rule with item selection to maximize Fisher information at the mastery threshold. In the first part of this dissertation, a new approach is proposed in which a time limit is defined for the test and examinees' response times are considered in both item selection and test termination. Item selection is performed by maximizing Fisher information per time unit, rather than Fisher information itself. The test is terminated once the SPRT makes a classification decision, the time limit is exceeded, or there is no remaining item that has a high enough probability of being answered before the time limit. In a simulation study, the new procedure showed a substantial reduction in average testing time while slightly improving classification accuracy compared to the original method. In addition, the new procedure reduced the percentage of examinees who exceeded the time limit. Another well-known stopping rule in AMT is to terminate the assessment once the examinee's two-sided ability confidence interval lies entirely above or below the cut score. The second part of this dissertation proposes new procedures that seek to improve such a variable-length stopping rule by coupling it with curtailment and stochastic curtailment. Under the new procedures, test termination can occur earlier if the probability is high enough that the current classification decision remains the same should the test continue. Computation of this probability utilizes normality of an asymptotically equivalent version of the maximum likelihood estimate (MLE) of ability. In two simulation studies, the new procedures showed a substantial reduction in average test length (ATL) while maintaining similar classification accuracy to the original stopping rule based on the ability confidence interval. In the last part of this dissertation, generalization to multidimensional CAT (MCAT) is examined. Research has shown that MCAT improves the precision of both subscores and overall scores compared to its unidimensional counterpart. Several studies have investigated the performance of MCAT in recovering examinees’ multiple abilities depending on the item selection methods. None of these studies, however, considered an item pool containing a mixture of multiple-choice (MC) and…

▼ Demographics in the United States continue to shift with a rapidly growing Hispanic population. On the other hand, a mismatch still exists between Hispanic students? enrollment in gifted and talented (G/T) programs and general programs. The under-representation of Hispanic students in G/T programs has been attributed to a lack of proper instrument to identify gifted students who are linguistically and culturally diverse; insufficient preparation of teacher in the initial teacher referral phases; and ambiguous definitions of intelligence and giftedness. In this study I investigated psychometric properties of the Hispanic Bilingual Gifted Screening Instrument (HBGSI) within an item response theory (IRT) framework. The HBGSI was developed with social-cultural context in mind and has been recommended for use in the first phase of teacher referral process. Participants in this study were Hispanic bilingual students in first to third grade, who participated in a large-scale longitudinal randomized study carried out in a Texas urban school district. The purpose of this study was to further validate HBGSI within the framework of IRT, exploring the factor structure and dimensionality of the instrument at the item level. I further tested the possibility of constructing an abbreviated version of HBGSI with fewer items for ease of administration, which would potentially lower the demand on the teacher?s time, enhance accessibility and facilitate increased usage of the instrument. Results revealed a bifactor structure with a strong general factor corresponding to overall giftedness among Hispanic bilingual students, and five domain factors regarding social responsibility, academic achievement, creative performance, problem solving, and native language proficiency. The multidimensional bifactor IRT model provided information related to each item concerning its discriminating power, thresholds and information regarding the latent constructs. Best items were selected while preserving the integrity of the original HBGSI, and cutting the length to almost half. Thus an abbreviated version of HBGSI was feasible and the adaptation is presented. Overall, this study further validated that the HBGSI holds promise in screening potential Hispanic bilingual students in elementary grades.

▼ The purposes of this study were to (a) provide insight into the use of item response theory (IRT) with psychomotor skills, (b) assess the psychometric properties of the Test of Gross Motor Development (TGMD) using IRT, and (c) provide a basis for future studies of the TGMD using IRT. The dichotomously scored TGMD is a test instrument which measures psychomotor skills in a framework similar to cognitive tests, thus providing a convenient "transitional" type test which can be used to examine the use of IRT with psychomotor skill tests. The present study employed data used by Ulrich (1985) in the original psychometric analysis of the TGMD. The data consisted of 913 subjects aged 3 to 10 years, nonhandicapped and 20 mildly mentally handicapped. Since IRT cannot provide accurate ability estimates at mastery levels of 0% and 100% mastery, 32 subjects were deleted from the record. Since the TGMD was found to be multidimensional, the test was analyzed by subtests so not to violate the unidimensionality assumption of IRT. Interpretation of traditional item statistics using classical test theory (CTT) and IRT item parameters revealed that item difficulty and item discrimination were closely related. The locomotor IRT difficulty parameters revealed a high negative correlation (r = -.87) with the CTT difficulty statistics, while the object control IRT difficulty parameters displayed a very high negative correlation (r = -.98) with their CTT counterparts. Item response theory discrimination parameters correlated highly with CTT discrimination statistics within the locomotor (r = .91) and the object control (r = .94) subtests. IRT analysis revealed that the locomotor subtest was less difficult (median difficulty = -.944) than the object control subtest (median difficulty = .053) and the object control subtest displayed a better discrimination index (median = 2.17) than the locomotor subtest (median = 1.54). In addition to difficulty and discrimination indices, IRT also provided the amount of information given by each item and subtest, which indicated the precision in measuring various ability levels. The locomotor subtest information was reported at I = 15.50, indicating adequate precision to measure low ability (Θ = -1.857). The object control information function showed that the subtest displayed more information (I = 18.24) at a slightly higher ability level (Θ = -1.643). The results of the item analysis revealed that all items (behavioral criteria) of the hop, leap, and the overhand throw displayed effective psychometric properties, while 9 out of 12 skills contained items that displayed poor psychometric characteristics and/or did not fit the two-parameter model. The run (items 1, 3, and 4), gallop (items 6 and 8), horizontal jump (item 18), skip (item 20), slide (items 23, 24, 25, 26), strike (items 27, 28, and 29), stationary bounce (item 32), catch (item 34 and 35), and the kick (item 38) should be revised. Since the TGMD is also used as a criterion-referenced test the decision validity of the mastery classification… Advisors/Committee Members: Dunn, John (advisor), Ringle, John (committee member).

Formal psychiatric symptom criteria are used to delineate the boundary between “normal” and “abnormal” behavior. In North America, the current official psychodiagnostic criteria for a multitude of psychiatric disorders are codified in the Diagnostic and Statistical Manual of Mental Disorders (4th Edition, text revision) (APA, 2000). Psychodiagnostic symptom criteria are indicators of psychopathological constructs that are clearly latent, however, it is somewhat astonishing that formal psychometric techniques that have been developed to model latent constructs have not been used to develop and evaluate psychodiagnostic symptom criteria (Aggen, Neale, & Kendler, 2005; Zimmerman, McGlinchey, Young, & Chelminski, 2006a, 2006b). There are two main psychometric paradigms that are currently in use: classical test theory and item response theory (Crocker & Algina, 1986). Classical test theory has been extensively used on both cognitive constructs and noncognitive constructs (Crocker & Algina, 1986; Embretson & Hershberger, 1999). Item response theory is considered to be theoretically superior to classical test theory and it has revolutionized the creation and evaluation of cognitive constructs (Crocker & Algina, 1986; Embretson & Hershberger, 1999; McDonald, 1999). However, item response theory has not been extensively utilized for the creation and evaluation of noncognitive constructs, even though it holds great promise in this regard (Reise, 1999; Reise & Henson, 2003). The proposed study will use classical test theory and item response theory to assess the psychodiagnostic symptom criteria for depression as found in the Diagnostic and Statistical Manual of Mental Disorders (4th Edition, text revision) (APA, 2000). The data to be used in the proposed study was collected in the National Comorbidity Survey – Replication, which was a nationally representative epidemiological community survey (Kessler et al., 2004; Kessler & Merikangas, 2004). The results of such a study will give a sophisticated psychometric perspective on the psychodiagnostic symptom criteria of depression that has not yet been available and it will provide valuable information on improving and refining future diagnostic symptom criteria of depression.

▼ [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The accuracy of test scores is a major concern in standardized testing for establishing test reliability and validity. Research evidence has suggested that aberrant response patterns on a test have serious implications for the accuracy of item calibration and ability estimation. Aberrant responses refer to examinees' test responses that are not based on their abilities, which are estimated by specified item response theory (IRT) models, but rather are affected by factors such as students' carelessness, cheating, guessing, or other sluggish behaviors on a test. In such cases, examinees respond to test questions in ways that violate the assumptions of the measurement IRT models to produce their test scores. Consequently, students' abilities are inaccurately measured. Existing research on aberrant response detection has focused on regular IRT models such as the Rasch model, two parameter logistic (2-PL) model, or three parameter logistic (3-PL) model. The purpose of this proposed study is to investigate the aberrant response detection using a testlet IRT model, which is commonly used in applied psychological measurement situation, and to explore how testlet effects influence Type I errors of the standardized log-likelihood person fit index to detect aberrant responses. Testlet effects are explored in two ways: 1) varied numbers of testlet items on tests; 2) varied magnitude of testlet variances on tests. Three aspects are explored in each of the simulation study: 1) Type I errors based on true abilities, ability estimates (posterior mode in this study), and Wainer's corrected ability estimates; 2) detection rates based on the above mentioned three methods; 3) model misspecification, that is, testlet items are misspecified as regular IRT items. Several important findings can be identified from the simulated studies: First, consistent with previous studies, inflated Type I errors for all simulated situations were observed when simulated true scores were used to calculate the standardized person fit index. Also, consistent with previous studies, Type I errors based on estimated abilities were conservative for most simulated conditions for testlet model in current research. Second, with regard to the influence of the number of testlet items on aberrant response detection, results indicated that the less number of testlet items, the better aberrant response detection rates at all simulated conditions while results can be improved if based on the corrected ability estimates for the testlet items. As for the influence of testlet variances on aberrant response detection, results showed that the smaller testlet variances on a test, the better detection rates at all simulated conditions. Corrected ability estimates performed well for aberrant response detection when large testlet variances presented on a test. Third, if testlet items were misspecified as regular IRT items and testlet effects were ignored, detection rates were higher for both simulated studies.… Advisors/Committee Members: Wang, Ze, 1979- (advisor).

▼ Cancer is the second leading cause of mortality in America and has a profound impact upon individuals, families, health care providers, and society at large. A substantial minority of cancer patients experience clinically significant symptoms of psychological distress, which can be associated with a wide range of negative health outcomes. Currently available screening measures narrowly define distress, are relatively primitive tools and their relationship to patient behavior is largely unknown. The current study sought to evaluate the psychometric properties and clinical utility of Distress Screening System (DSS), a comprehensive measure developed to address these limitations. There were 492 individuals diagnosed with cancer assessed in the current study through mail-out questionnaires and follow-up phone interviews. The majority were female (71.3%), married (59.6%) and Caucasian (68.6%) or African American (20.7%), with a mean age of 61.41 years (SD = 12.92). Preliminary and exploratory factor analysis revealed the DSS to possess appropriate internal and concurrent validity, and to be sufficiently unidimensional to proceed with further examination. Item response analysis revealed moderate overall model fit, with the majority of items performing well with adequate levels of discrimination and difficulty across the distress continuum. The DSS was most accurate in assessing moderate to high levels of distress. Examination of clinical utility revealed no significant advantage for the DSS in predicting quality of life or referral preference. The DSS appears to be a psychometrically valid measure of distress and provides the basis for a broader conceptualization of this construct. The majority of items performed well within a unidimensional item response framework and may therefore be suitable to utilize within a computerized assessment format. Despite these results, the DSS did not demonstrate a significant advantage in the prediction of participants’ quality of life or referral preference. The current study provides a foundation for future work examining the conceptualization of distress and development of screening tools within an advanced psychometric framework and computerized administration. Advances in empirical measurement and clinical assessment are vital in addressing the ongoing challenge of providing nationwide comprehensive cancer care. Advisors/Committee Members: Scott M.

▼ Response times (RTs) on test items are a valuable source of information concerning examinees and the items themselves. As such, they have the potential to improve a wide variety of measurement activities. However, researchers have found that empirical RT distributions can exhibit a variety of shapes among the items within a single test. Though a number of semiparametric and “flexible” parametric models are available, no single model can accommodate all plausible shapes of empirical RT distributions. Thus the goal of this research was to study a few of the potential consequences of RT model misspecification in educational measurement. In particular, two promising applications of RT models were of interest: examinee ability estimation and item selection in computerized adaptive testing (CAT). First, by jointly modeling RTs and item responses, RTs can be used as collateral information in the estimation of examinee ability. This can be accomplished by embedding separate models for RTs and item responses in Level 1 of a hierarchical model and allowing their parameters to correlate in Level 2. If the RT model is misspecified, a potential drawback of this hierarchical structure is that any negative impact on estimates of the RT model parameters may, in turn, negatively impact ability estimates. However, a simulation study found that estimates of the RT model parameters were robust to misspecification of the RT model. In turn, ability estimates were also robust. Second, by considering the time intensity of items during item selection in CAT, test completion times can be reduced without sacrificing the precision of ability estimates. This can be done by choosing items that maximize the ratio of item information to the examinee’s predicted RT. However, an RT model is needed to make the prediction; if the RT model is misspecified, this method may not perform as intended. A simulation study found that whether or not the correct RT model was used to make the prediction had no bearing on test completion times. Additionally, using a simple, average RT as the prediction was just as effective as model-based prediction in reducing test completion times.

▼ This study compares item and examinee properties, studies the robustness of IRT models, and examines the difference in robustness when using model-data-fit as a robustness criterion. A conceptualization of robustness as a statistical relationship between model assumption violation and invariance properties has been created in this study based on current understanding on IRT models. Using real data from British Columbia Science Assessments, a series of regressional and canonical analyses were conducted. Scatterplots were used to study possible non-linear relationships. The means and standard deviations of "a" and "c" parameter estimates obtained by applying the three-parameter model to a data sample were used as indices of equal discrimination and non-guessing assumption violation for the Rasch model. The assumption of local independence was taken as being equivalent to the assumption of unidimensionality, and Humphreys' pattern index "p" was used to assess the degree of unidimensionality assumption violation. Means and standard deviations of Yen's Q [i subscript] were used to assess the model-data-fit of items at the total test level. Another statistic to assess the model-data-fit of examinees (D [i subscript]) was created and validated in this study. The mean and standard deviation of D [i subscript] were used to assess model-data-fit of examinees at the total test level. The statistics used in this study for assessing item and ability parameter estimate invariance properties were correlations between estimates obtained from a sample and the estimates obtained from an assessment data file. It was found that model-data-fit of items and model-data-fit of examinees are two statistically independent total test properties of model-data-fit. Therefore, there is a necessity in practice to differentiate model-data-fit of items and model-data-fit of examinees. It was also found that item estimate invariance and ability estimate invariance are statistically independent total test properties of invariance. Therefore, there is also a necessity in practice to differentiate item invariance and ability invariance. When invariance is used as a criterion for robustness, the three-parameter model is robust for all the combinations of sample size and test length. The Rasch model is not robust in terms of ability estimate invariance when a large sample size is combined with a moderate test length, or when a moderate sample size is combined with a long test length. Finally, no significant relationship between model-data-fit and invariance was found. Therefore, results of robustness studies obtained when model-data-fit is used as a criterion and the results when invariance is used as a criterion may be totally different, or even contradictory. Because invariance is the fundamental premise of IRT models, invariance properties rather than model-data-fit should be used as criteria for robustness.
