✦ Synopsis

Objective:

To validate the hamilton depression (17) and montgommery and asberg depression scales as research instruments in older depressed community residents.

Design:

External validation against gms/agecat case level in the recruitment of older community residents for an antidepressant trial.

Analyses:

Receiver operator curves were generated for each rating scale, using gms/agecat case level in external criterion. the sensitivity, specificity, positive and negative predictive values of both rating instruments were examined in the whole sample and age and gender subgroups. madrs and ham-d cut-off scores differentiating gms/agecat cases from subcases were identified.

Results:

Ham-d cut-off score of 16 and madrs score of 21 were identified as differentiating case from sub-case. diagnostic accuracy of both instruments was good, reflecting good sensitivity and specificity across both genders and sub-age groups.

Conclusions:

Both scales performed well in this population. these scores provide researchers with externally validated and clinically relevant cut-off scores in designing trials in the management of older depressed community residents.
