Hello Im, 

The Connor-Davidson Resilience Scale, the Resilience Scale for Adults and the Brief Resilience Scale have the best psychometric ratings.

I would like to recommend you the attached article. Hope it helps. 

Best wishes,

A slightly off-topic comment: human reslilience is eroded by stresses stored in the nervous system. Over a typical lifetime, many thousands of overloads of perception and cognition create many thousands of internal stress. Deep rest, such as is provided by the transcending technique, can systematically eliminate internal stresses. Typical research to validate this uses the startle response to measure resilience. Related research includes measures of autonomy and field independence.

This is tangential to your immediate question regarding measures of resilience, but as a kind of sidebar, I thought I'd mention the concept of "nadir experiences" as discussed by some in (primarily humanistic) psychology a generation ago. Following on Maslow's observed correlation between self-actualization and the occurrence of spiritual-like "peak experiences," it was noted that some among us also effect growth and realization of personal potential in response to "hitting bottom" types of life events, which became dubbed "nadir experiences."

More recently, somewhat analogous discussions can be found among positive psychologists in connection with separating out within "well-being" indices the elements of hedonic subjective experience (i.e., pleasure) and "eudaemonic" (also spelled "eudaimonic") experience, with the latter tied more to valued experiences of substance and meaningfulness which, as often as not, are not particularly pleasant. That discussion remains to my mind an ongoing exploration (i.e., they've got a ways to go to clarify the pertinent construct), but among researchers who have touched on it are:
