Screening Tool: Seasonal Affective Disorder

This survey is designed to provide a quick assessment of whether you show signs and symptoms of Seasonal Affective Disorder. However, no test is 100% accurate. No matter what your score is, you should seek help if you have any concerns about yourself or your loved ones.


Are there times when you get depressed (with symptoms such as low mood, poor concentration, low energy, increased cravings for carbohydrates, and increased need to sleep), along with:

1. ... these periods happening for at least two years in a row?
2. ... these periods happening during the same season every year (e.g. fall/winter) and then improving by the following season (e.g. spring/summer)?

The screening questionnaire used here is based on diagnostic criteria from the DSM-IV criteria for Major Depressive Disorder, with Seasonal Pattern Specifier. To our knowledge, there is not yet any free, public domain, validated screening scale for this condition. Nonetheless, if you are aware of such a scale, please let us know.
