[5][2][6] The client rates how much each item relates to them on a 5-point scale as follows:[2] The point values of the chosen answer choices are then summed to produce a total measure score.
[7] The SIAS measures social interaction anxiety, which refers to distress when meeting and talking with other people, whether they be friends, members of the opposite sex, or strangers.
[1] Evaluated through Cronbach's alpha, the SIAS demonstrates high levels of internal consistency,[1][2][7][8][9] meaning that different items on the test are correlated.
In addition, the scale has high test-retest reliability, as it continues to correctly identify social anxiety and phobia after a period of time has passed.
[9] In addition, there are moderate to high correlations between the SIAS and other scales testing fear, depression, and locus of control, which are all related to social anxiety.
[4] The SIAS is highly correlated with the SPS, suggesting that subjects from the community may not discriminate between the types of situations assessed in the two scales.
