Objectives:
The aim of this study is to adapt the Problem Drinking Scale (SPP) for quantitative and qualitative analysis of alcohol use disorders conceptualized according to DSM-5 classification.

Methods:
708 adults were studied, all with different levels of alcohol consumption, were examined, including 91 who were treated for addiction and were recruited in addiction treatment clinics. The remaining persons, with different socio-demographic characteristics, were recruited using the "snowball" method. The validity was assessed by correlating the results obtained with the AUDIT test, and reliability by internal compatibility analysis.

Results:
The analysis presented demonstrates high validity and reliability in most areas, which means that SPP is a tool that can be used in clinical practice. Criterion validity was calculated by correlating SPP results with AUDIT (r=0.88, p <.01). The results in particular areas range from r=0.86 (Difficulty in controlling drinking) to r=0.77 (Pharmacological dependence). Reliability was calculated using the split-half method, individual values of Cronbach alpha coefficients with Spearman-Brown correction vary in specific areas from 0.89 (Difficulty in controlling drinking) to 0.65 (Risky use of substances). In none of the areas the results were lower than 0.60.

Conclusions:
SPP is a useful research tool for quantitative and qualitative analysis of alcohol use disorders. This scale is helpful in making a full and accurate clinical diagnosis taking into account the depth of the disorder and in monitoring changes in the treatment process.
