Help, Teach, Counsel: How Terminology Changes in the ProQOL-5 Impact Score Reliability

Abstract

Objective: This study evaluated score reliability of the Professional Quality of Life Scale (ProQoL) when contextualizing help to a relevant derivative. Method: The researchers evaluated score reliability across three datasets among school-based professionals (n = 122), teachers (n = 216), and mental health professionals (n = 543) using Cronbach’s alpha, McDonald’s omega, inter-item correlations and visual analysis. Results: Score reliability was acceptable across samples. However, item analysis indicated variability in responses indicating participants’ extracting different meaning or relevance to the items. Terminology changes may extract different meaning based on profession resulting in measurement error. Conclusions: Findings highlight use of one-word derivative changes to items may impact score reliability based on the professional activities represented. Researchers should adjust item terminology for clarity and relevance to all the professions represented in the sample. Evidence of the nature of professional activities with client or student trauma to secondary traumatic stress is presented.
