The reliability of the survey was strengthened by the exclusion of the first (“being able to keep busy all the time”)
of the 28 items in the satisfaction portion of the survey. The reliability coefficient for the new 27-item scale
increased from .9551 to .9555. As a diagnostic rule of thumb, the agreed upon lower limit for Cronbach’s alpha is
.70, though it may decrease to .60 in exploratory research (Hair, Jr., Anderson, Tatham, & Black, 1998). This
scale posted a high measure of reliability.
