The Resilience Scale for Adults developed by Wagnild and Young in
1993 is the most frequently used measurement scale with reliability
and validity supported by several small studies since 1990: Cronbach's
alpha coefficient was consistently acceptable and moderately high
ranging from 0.73 to 0.91 (Wagnild, 2009). According to De Santis
(2008), Wagnild and Young (1993) has not been used to study
resilience in the context of HIV infection, but researcher like Farber et
al. (2000) have used the dispositional resilience scale to measure
related concepts of hardiness to study resilience in patients with HIV.
