Convergence between the Penn Alcohol Craving Scale and diagnostic interview for the assessment of alcohol craving
IntroductionThe Penn Alcohol Craving Scale (PACS) is one of the most widely used instruments to measure craving for alcohol. Recent research has suggested that scores on the PACS can be used as a “stand in” for the diagnostic criterion of alcohol craving with a proposed cutoff of >20 on the PACS indicating a “positive” alcohol craving symptom. The present study examined the convergence between the PACS and face-to-face diagnostic interview for the assessment of alcohol craving.MethodA sample of non-treatment seeking heavy drinkers (N?=?338) enrolled in experimental studies of AUD completed the PACS as well as a face-to-face diagnostic interview for AUD, which included the craving item from the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA).ResultsUsing the PACS cut-off score of >20, 12.9% (N?=?43) of the sample met criteria for alcohol craving compared to 21% (N?=?74) of the sample meeting criteria based on the diagnostic interview. Using the PACS cutoff of >20, sensitivity (i.e., true positive rate) was 41% and specificity (i.e., true negative rate) was 95%. Exploratory analyses suggested that a cut-off score of ≥15 achieved the optimal balance of sensitivity (67%) and specificity (81%) in our sample.ConclusionsAdvancing the assessment of alcohol craving and the conversion from DSM-IV to DSM-5 diagnostic criteria represents an important research direction. The present study recommends that a PACS score cut off of ≥15 should be used as an indicator of clinically significant alcohol craving in community samples of non-treatment seekers.
