Disclosed are methods and systems for detecting an abnormal stress condition in a subject or group of subjects. Included is a risk evaluation system monitoring people, wherein a control unit in a stress management system obtains mental health information and records same in a measurement information database. The control unit then specifies a pattern in a reference pattern database and obtains the measurement information relating to this pattern from the measurement information database. The control unit in the stress management system (20) then revises a standard pattern based on individual attributes or work attributes. Next, the control unit performs pattern matching and determines whether or not attention is required. If the determination is that attention is required, the control unit presents an alert and an advice. This enables work, organization, and member risks to be appropriately evaluated based on changes in mental health information.
