The SSI is a 140 item inventory that:
a) measures the strength of a number of stressors that are often present in a stepfamily setting,
b) evaluates the extent to which these stressors may be impacting you personally, and
c) guages the strength of a collection of stress-reducing resources that can help you to manage the stressors identified.
It should take you about 15 minutes to complete all 140 questions.
