Show moreObjectives. The main objective of this study was to determine whether reduced autobiographical memory specificity is also a marker for depression in older adults. To answer this question two experiments and a prospective longitudinal clinical study were executed with the autobiographical memory task (AMT) as measure for memory specificity. The objective of the 1st experimental study was to assess the influence of a negative mood induction versus the effect of multiple testing in a neutral condition in 58 never depressed (ND) elderly. In the 2nd experimental study a negative mood was induced in 63 participants remitted from depression (RD) compared to 60 matched ND controls. All participants were 55 and older. Lastly, the predictive value of the AMT for the course of depressive symptoms was assessed in the RD individuals over a 14-17 months follow-up (FU) period. Results. Performance did not improve with repeated testing, but a trend was found suggesting fatigue. There was no difference between the RD and ND group on baseline AMT. The mood induction had no effect on the AMT regardless of clinical history. Changes in the level of depressive symptoms at the 14-month FU were predicted by residual symptoms at baseline and the number of previous depressive episode, but not by baseline AMT, changes in AMT or mood after mood induction. Conclusion. The results of this study suggest that memory specificity on the AMT may not be a useful marker for vulnerability for clinical depression in older adults. Show less

Show moreIn a recent study, Rude, Gortner, and Pennebaker (2004) found word use to be related to depression and vulnerability to depression in the essays of college students. We sought to replicate and extend these findings in a clinical sample. Written essays of 304 psychiatric outpatients with a personality disorder and a mixed psychiatric profile on DSM-IV axis-1 and 108 healthy controls were examined with word count software. Data on the tendency to be discrepant about the current self compared to a more ideal self were also gathered. We found that psychiatric outpatients in general used more words referring to the self and negative emotion words and fewer positive emotion words, compared to healthy controls. However, word-use proved unrelated to depression specifically. Actual-ideal self discrepancies were related to patient status and to current depression. Contrary to our hypothesis, these discrepancies did not correlate with the use of words referring to the self. We conclude that the negative content and self-focus of written essays and high levels of discrepancy reflect a negative thinking style that is common to a range of psychiatric disorders rather than being specific to depression.

Show moreIn the Netherlands the Coping with Depression (CWD; Lewinsohn & Clark, 1984) course for elderly has been implemented in the prevention arm of the community-based mental health care system. The study’s aim was the effectiveness (immediate and long-term) of the course in this real life setting. Enrolment of all 318 participants was the responsibility of the mental health care professionals in charge of the course. The immediate effect was studied in a random design using a waitlist group as control group; the long-term effect was analyzed in a naturalistic design. The Center for Epidemiological studies Depression scale (CES-D; Radloff, 1977) was used as the outcome measure. A wide range of variables related to incidence, severity, course and remittance of depression were included as predictors of immediate and long-term outcome. Results. The level of depressive symptoms varied from slight to being severely depressed i.e., meeting the criteria for a major depressive episode (MDE). Effect size: for non-depressed 0.32, for those with a MDE 0.92. The four predictors – anxiety, MDE, previous MDE, and education level - that were statistically significant had no clinical significance and did not justify further triage at intake. At the conclusion of the course 62% still had a CES-D score above 16, which is an indication that a clinical relevant depression is persisting. These participants should be advised to seek further treatment. Show less
