Overview

self-report measure consisting of 20* 5-point Likert Scale questions on four subscales.

originally the survey consisted of 20 items but original question 15 is not used for analyses as it does not significantly load
onto any of the four subscales.
A revised version of the survey replaces q15 with an alternative. Check radioButtons.q15 below for a possible alternative.
