The SAD PERSONS scale is an acronym utilized as a
mnemonic device. It was first developed as a clinical assessment tool for medical professionals to determine suicide risk, by Patterson et al.[1] The Adapted-SAD PERSONS Scale was developed by Gerald A. Juhnke for use with children in 1996.
Recent studies have found although the scale has specificity, its sensitivity is so low it is of no clinical value;[2][3] moreover it may actually be clinically harmful.[4] This measure has also been criticized for being an index of risk factors that may not be applicable to individuals, and that suicide risk be assessed with more valid measures of the individual's current risk level.[5]
