It’S All The Rage: An Animated Approach To Screening For Postpartum Depression, Amanda Gorham Dec 2020

It’S All The Rage: An Animated Approach To Screening For Postpartum Depression, Amanda Gorham

Doctoral Dissertations

Postpartum depression presents a complication for mothers which can, in some cases, be severe and even life-threatening. Instruments commonly used to screen for this psychological condition have been challenged by an extensive body of literature, with many mothers being unidentified and even untreated for their symptoms. The presented research introduces a newly developed screening instrument for detecting probable postpartum depression using text-free scenario-based animations, based on the lived experience of the condition as qualified by empirical research and the existing body of literature. Developed items were controlled for quality via Think Aloud Protocol and alignment studies with subject matter experts …


Detecting Candidate Preknowledge Of Items Using A Predictive Checking Method, Xi Wang Nov 2016

Detecting Candidate Preknowledge Of Items Using A Predictive Checking Method, Xi Wang

Doctoral Dissertations

In on-demand high-stakes testing programs such as GRE and TOEFL, some items are repeatedly used across test administrations to reduce the cost of developing new items constantly. Item exposure provides an opportunity for examinees to have knowledge of particular test items in advance of their administration. It poses a threat to test security and ultimately will result in invalid test scores. Therefore, many testing programs conduct quality control to monitor test compromise at individual and/or group level. A predictive checking method is proposed in this study to detect examinee preknowledge on exposed items. We consider a scenario where a test …


Identifying Examinees Who Possess Distinct And Reliable Subscores When Added Value Is Lacking For The Total Sample, Joseph A. Rios Nov 2016

Identifying Examinees Who Possess Distinct And Reliable Subscores When Added Value Is Lacking For The Total Sample, Joseph A. Rios

Doctoral Dissertations

Research has demonstrated that although subdomain information may provide no added value beyond the total score, in some contexts such information is of utility to particular demographic subgroups (Sinharay & Haberman, 2014). However, it is argued that the utility of reporting subscores for an individual should not be based on one’s manifest characteristics (e.g., gender or ethnicity), but rather on individual needs for diagnostic information, which is driven by multidimensionality in subdomain scores. To improve the validity of diagnostic information, this study proposed the use of Mahalanobis Distance and HT indices to assess whether an individual’s data significantly departs …
