Development and Initial Validation of the PROMIS(®) Sexual Function and Satisfaction Measures Version 2.0.

Introduction: The Patient-Reported Outcomes Measurement Information System (PROMIS)(®) Sexual Function and Satisfaction measure (SexFS) version 1.0 was developed with cancer populations. There is a need to expand the SexFS and provide evidence of its validity in diverse populations.

A preliminary multifactorial approach describing the relationships among lower extremity alignment, hip muscle activation, and lower extremity joint excursion.

Context: Multiple factors have been suggested to increase the risk of faulty dynamic alignments that predict noncontact anterior cruciate ligament injury. Few researchers have examined this relationship using an integrated, multifactorial approach.

Objective: To describe the relationship among static lower extremity alignment (LEA), hip muscle activation, and hip and knee motion during a single-leg squat.

Maintaining Content Validity in Computerized Adaptive Testing.

A major advantage of using computerized adaptive testing (CAT) is improved measurement efficiency; better score reliability or mastery decisions can result from targeting item selections to the abilities of examinees. However, this type of engineering solution can result in differential content for different examinees at various levels of ability. This paper empirically demonstrates some of the trade-offs which can occur when content balancing is imposed in CAT forms or conversely, when it is ignored.
