Mental disorders with complex presentations often include depressive symptoms, which in turn might lead to misdiagnosis, contributing to disease burden statistics. The goal of the present study was to investigate whether a common depressive-symptom overlap was present in unstructured online forum posts, specifically on Reddit. The k-nearest neighbours voting classifier was fitted on posts downloaded from Reddit from seven mental-health support groups (depression, anxiety, bipolar, borderline personality, narcissistic personality, antisocial personality, schizophrenia). Phrases that contributed the most of the confusion were identified. The misclassification was asymmetrical: posts from four support groups (anxiety, bipolar, borderline personality, and schizophrenia) were misclassified often as being from the depression support group, but depression support group posts were not equally likely to be misclassified as being from another support group. Unstructured, unprompted self-disclosure datasets show high propensity of depressive symptoms, and strong convergent validity with existing theoretical frameworks and clinical findings. |
