Suicidal Ideation Attributes Scale (SIDAS)

The SIDAS is designed to screen individuals in the community for presence of suicidal thoughts and assess the severity of these thoughts. It consists of five items, each targeting an attribute of suicidal thoughts: frequency, controllability, closeness to attempt, level of distress associated with the thoughts and impact on daily functioning. Responses are measured on a 10-point scale. Items are coded so that a higher total score reflects more severe suicidal thoughts.

Scoring

Responders who respond “0 – Never” to the first item skip all remaining items and score a total of zero.

Total SIDAS scores are calculated as the sum of the five items, with controllability (item 2) reverse scored (10=0, 9=1, …, 0=10).
Total scores range from 0 to 50.

Scores of >21 indicated high risk of suicide behavior.
