Evaluating an assessment scale of irrational beliefs for people with mental health problems

In this paper, Douglas MacInnes examines the validity of a measure of irrational beliefs, the Shortened General Attitude and Belief Scale (SGABS). He examines the overall correlation between the various subscales of the measure, the criterion validity and construct validly of the instrument, as well as internal consistency. Results show that the measure had good validity and was a useful measure of irrational beliefs for clinicians and researchers working in the area of cognitive behaviour therapy
