Systematic review of neurocognition and occupational functioning in major depressive disorder
Bibliographic record
Abstract
Occupational impairment accounts for much of the burden and economic costs associated with major depressive disorder (MDD). Many studies have documented neurocognitive deficits in MDD, and depression-associated cognitive dysfunction would be expected to have significant effects on occupational functioning. We systematically reviewed the literature for studies on neurocognition and occupational functioning in MDD. Electronic databases (e.g., MEDLINE, PsychInfo and Cochrane Clinical Trials) were searched using appropriate terms and bibliographies of relevant publications were scanned for additional citations. Two reviewers independently reviewed papers for inclusion and data extraction, with conflicts resolved by consensus. Inclusion criteria were diagnosis of MDD using validated criteria (e.g., DSMâÂÂIV or ICDâÂÂ10), use of objective neuropsychological tests and use of a specific measure of occupational functioning. Of 630 citations identified in the initial search, only two studies met inclusion criteria and were included in a qualitative review. Both had significant methodological limitations. Nonetheless, the depressed samples had significant neurocognitive deficits that were associated with employment status and work impairment. Neurocognitive dysfunction is probably associated with impairment in occupational functioning in individuals with MDD, but the evidence is limited. Further research should examine specific cognitive domains, and use validated measures of work functioning and productivity.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
