Five experienced clinical psychologists and five psychiatrists validated the items and as a result, 33 items of the scale were retained out of 44 items. This preliminary study was conducted on 81 diagnosed participants (24 males and 57 females) who were selected through purposive sampling technique. All the participants were diagnosed by expert psychologists and psychiatrists. Results: Factor analysis revealed two factors namely mood liability and insecure dependence respectively.
