Changes in directed attention and short-term memory in depression.
This study examined changes in directed attention and short-term memory in depression using a newly constructed battery of computerized measures. A repeated measures design was used with two sample groups; 25 individuals meeting DSM-IV criteria for Major Depression and a group-matched comparison sample of 27. Both groups were tested at three points in time over a 10-week period. Test-retest reliability of the measures was examined. Profile analysis demonstrated that there were differences between the depressed and comparison groups in both directed attention and short-term memory. Recommendations for specific improvements in the testing battery are discussed. The ability to detect changes in directed attention and short-term memory may have clinical utility in early detection of impending onset of depression or subtle residual symptoms of an acute episode that may impair functioning or signal a relapse.
