A Note on Older Versions of the ProQOL: Compassion Satisfaction and Fatigue Test
for the most current version of the Professional Quality of Life
Scales, the ProQOL. This revised version replaces the Compassion
Satisfaction and Fatigue Test, the Compassion Fatigue Test and the
Compassion Fatigue Self-Test. We no longer support these earlier
versions of the ProQOL and strongly advise that it not be used due to
the known psychometric problems.
Inevitably work is done with an older
version or publications lag for years between data collection and
publication. The ProQOL has two solutions for dealing with these issues. Because the ProQOL 5 uses standardized scoring it is possible to compare the ProQOL III, ProQOL IV and ProQOL 5 data. While there are some differences between the versions of the scales, the subscales are not greatly different, only refined. The scales have always had good to very strong internal reliability which improves the chance that comparing across versions will be acceptable. This is particularly the Compassion Fatigue scale which has always had an alpha reliability between .84 and .90. When comparing data across the three versions the greatest risk is a loss of precision. The older versions had more statistical error associated with them than the IV or the 5 which has a very small standard error of the estimate.
Regardless of the version of the measure used. It is important to include in your writing that there newer versions and that the latest information can be found at www.ProQOL.org. This will help readers in the future know where to find the latest information on the scale.
