Short quiz to assess seasonality.
"How Seasonal are You?
Most people are seasonal, though some are more so than others. In fact, over 90 percent of all those who responded to a survey conducted in Maryland, about thirty-nine degrees north, reported that they felt some difference in mood, energy, or behavior with the change of seasons. In Chapter 3 of The Winter Blues, you will see how to determine how seasonal you are by means of the Seasonal Pattern Assessment Questionnaire (SPAQ). Question 2 of the SPAQ is reproduced below."
