BSMAS Item Characteristic Curves (ICCs). Here, theta (θ) represents latent trait levels, and probability indicates the likelihood of endorsing an item based on difficulty (β) and latent trait level. The BSMAS is based on the components model of addiction (Griffiths, 2005) with each item representing an aspect of the problematic behavior (Item 1 = Salience, Item 2 = Tolerance, Item 3 = Mood modification, Item 4 = Relapse, Item 5 = Withdrawal, Item 6 = Conflict).
