Validation of the Polish version of the Penn Alcohol Craving Scale (PACS).

OBJECTIVES

The conducted studies were aimed at making a Polish adaptation of the Penn Alcohol Craving Scale (PACS) by B. Flannery and co-workers. The Scale is a self-assessment method, it comprises 5 statements, and is designed to assess alcohol craving experienced by a patient in a week prior to the examination.

METHODS

550 patients with diagnosed alcohol dependence syndrome were examined, and the final analysis included results of 510 persons. The examined group consisted of 396 men and 114 women. The study was made in the 3rd week of their alcohol treatment. There were used: the PENN Craving Scale, the Alcohol Dependence Development Scale (SRUA) (the part in which craving is dealt with), a clinical interview with specially prepared questions about alcohol craving experienced last month and last week, and the Yale-Brown Obsessive Compulsive Intense Drinking Scale.

RESULTS

The Polish version of the Penn Scale is characterised by very good psychometric properties - it is a reliable and valid tool. The exploratory and confirmatory factor analyses have proved the existence of one factor. The internal consistency, assessed on the basis of Cronbach's alpha, equalled 0.89. The method displays statistically significant (majority p < 0.0010) relationships with levels of craving experienced last year, last month, and last week before the examination, and also with total score on the Yale-Brown Scale.

CONCLUSIONS

The effects of the conducted adaptation works on the Penn Scale speak for recommending the method for scientific research and use in therapeutic practice.
