PMID: 283831

Description of a 20 item scale with 5 subscales each having 4 items - focus is on withdrawal symptoms. Internal consistency SADQ subscales correlate with SADQ total 0.69 to 0.80. Construct validity single factor accounting for 53% of variance. Concurrent validity‣ clinical Rating correlates with SADQ 0.63.
