Evaluation of Two Interviewing Skills Measures: An Instrument Validation Study

Abstract

This article reports an initial validation of an instrument that measures
basic interviewing skills and compares its psychometric results with another instrument
that has been used more frequently to measure similar skills. Four field supervisors
rated 30 students’ videotaped interviews (N=120) using two instruments, the
validation, and a comparison instrument. The current validation instrument had
high internal consistency reliability, a clear factor structure, and performed well in
construct validity evaluations. These preliminary results supported the instrument’s
internal consistency reliability, content, factorial, and construct validity. The validation
instrument had higher internal consistency reliability, lower errormeasurement,
and amore interpretable factor structure than the comparison instrument.
