Using a computer to automate self-reporting of mood does not appear to bias the collected data. The demographic characteristics of the patients using the automated data collection tool are very similar to those found in studies using paper-based tools. The prevalence of home computers is high in all industrialized countries. After grouping patients by severity of illness using clinician-rated HAMD and YMRS scores, no significant effects of demographics were found on the computerized self-ratings of mood by patients with bipolar disorder. Similar to studies using paper-based self-reporting, results from studies of patients using ChronoRecord software on a home computer to report mood can be generalized.
