What Do We Mean When We Say “Pass Rate”?

Pass rates are key assessment statistics which are calculated for nearly all high-stakes examinations. In this article, we define the terminal, first attempt, total attempts, and repeat attempts pass rates, and discuss the uses of each statistic. We also explain why in many situations one should expect the terminal pass rate to be the highest, first attempt pass rate to be the second highest, total attempts pass rate to be the third highest, and repeat attempts pass rate to be the lowest when repeat attempts are allowed. Analyses of data from 14 credentialing programs showed that the expected relationship held for 13 out of 14 of the programs. Additional analyses of pass rates for educational programs in radiography in one state showed that the general relationship held at the state level, but only held for 6 out of 34 educational programs. It is suggested that credentialing programs need to clearly state their pass rate definitions and carefully consider how repeat examinees may influence pass rate statistics. It is also suggested that credentialing programs need to think carefully about the meaning and uses of different pass rate statistics when choosing which pass rates to report to stakeholders.     

Construct validity of the childbirth trauma index for adolescents

The potentially traumatic nature of childbirth for adult mothers has been confirmed in research; however, adolescent childbirth trauma is unexplored. This article presents research on the construct validity of the Childbirth Trauma Index by providing a conceptual analysis of psychological childbirth trauma, factor validity of the Childbirth Trauma Index, and discussion of testing the Childbirth Trauma Index via contrasted-groups approach. Childbirth trauma can result in an acute stress reaction or actual posttraumatic stress disorder. Using subjective reports, the Impact of Event Scale, and the Childbirth Trauma Index, an appraisal of birth trauma, trauma impact, and indicators associated with childbirth trauma were revealed among 112 adolescents. Clinical implications and research recommendations are offered.     

Evaluation of a randomized intervention to delay sexual initiation among fifth-graders followed through the sixth grade

US adolescents initiate sex at increasingly younger ages, yet few pregnancy prevention interventions for children as young as 10-12 years old have been evaluated. Sixteen Washington, DC schools were randomly assigned to intervention versus control conditions. Beginning in 2001/02 with fifth-grade students and continuing during the sixth grade, students completed pre-intervention and post-intervention surveys each school year. Each year, the intervention included 10-13 classroom sessions related to delaying sexual initiation. Linear hierarchical models compared outcome changes between intervention and control groups by gender over time. Results show the intervention significantly decreased a rise over time in the anticipation of having sex in the next 12 months among intervention boys versus control boys, but it had no other outcome effects. Among girls, the intervention had no significant outcome effects. One exception is that for both genders, compared with control students, intervention students increased their pubertal knowledge. In conclusion, a school-based curriculum to delay sexual involvement among fifth-grade and sixth-grade high-risk youths had limited impact. Additional research is necessary to outline effective interventions, and more intensive, comprehensive interventions may be required to counteract adverse circumstances in students' lives and pervasive influences toward early sex.ClinicalTrials. gov identifier: NCT00341471.
