The current study explores the rates of valid and invalid MMPI-2 protocols across testing conditions, as well as the test taker's preference for each format and the amount of time spent responding to the items. Participants were 203 undergraduate students (90 men and 113 women) from a Midwestern university. Participants completed either a CC or P&P version of the MMPI-2 along with a supplemental survey to assess for participants' testing format preference. Overall, results suggest that while testing format did not affect the number of valid MMPI-2 protocols produced, the CC version was rated more favorably by participants and took significantly less time to complete. / Department of Psychological Science

Impetus in recruiting and testing candidates via the Internet results from the popularity of the World Wide Web. There has been a transition from paper-pencil to online testing because of large number of benefits afforded by online testing. Though the benefits of online testing are many, there may be serious implications of testing job applicants in unproctored settings. The focus of this field study was two-fold: (1) to examine differences between the proctored and unproctored online test administrations of the ipsative version of Occupational Personality Questionnaire (OPQ32i and (2) to extend online testing research using OPQ32i with a U.S population. A large sample (N = 5223) of archival selection data from a financial company was used, one group was tested in proctored and the other in unproctored settings. Although some statistical differences were found, very small to small effect sizes indicate negligible differences between the proctored and unproctored groups. Principal component analysis with varimax rotation was conducted. The scales not only loaded differently from the Great Eight factor model suggested by SHL, but also differently for the two groups, limiting their interpretability. In addition to the limitations and future directions of the study, the practical implications of the results for companies considering unproctored, online personality testing as a part of their selection process are discussed.

A Life Complexity Scale (LCS) and Life Diversity Scale (LDS) were developed to assess the richness and diversity of experiences in individuals. In study 1, three hundred and fifty mTurk workers completed the LCS and other standard measurements of personality to assess the scales validity and correlation. Exploratory Factor Analysis and Structural Equation Modeling were used to look into the structure of the scale. Four factors were selected according to Scree plot solution and theoretical framework including: complexity, basic, uncertainty, and complicated. In study 2, four hundred mTurk workers completed the LDS along with other measurements of personality, depression, and social support. Exploratory Factor Analysis and Structural Equation Modeling were used to explore the structure of the scale finding a single factor solution. The results indicate that both scales have good reliability LCS (Omega total = 1.02) and LDS (Omega total = .8). The associations with other personality traits are explored and recommendations for future research are signaled. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2019. / FAU Electronic Theses and Dissertations Collection
