OVERVIEW
___________________________________________________________________________________________________________________	

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

*Note: 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.
