Social Phobia Inventory (SPIN; Connor et al., 2000)
The SPIN is a 17-item questionnaire assessing social phobia (SAD) symptoms over the last week, participants indicate how much they are “bothered” by problems such as “I avoid going to parties” and “talking to strangers scares me” on a 0-4 scale with answers of “not at all” scoring 0 points, through to“extremely” which scores the maximum 4 points, resulting in a range of 0-68 with a score of 19 reliably distinguishing between those with SAD and controls (Conner et al., 2000).
