Problem Drinking Scale (PDS) – psychometric characteristics

Summary
Aim. The presented study aims at checking and demonstrating the psychometric characteristics of the new tool – the Problem Drinking Scale (PDS), which is used for quantitative and qualitative analysis of alcohol use disorders conceptualized according to DSM-5.
Method. 708 adults with different levels of alcohol consumption were examined, including 91 individuals recruited in addiction treatment clinics. The remaining persons, with different socio-demographic characteristics, were recruited using the snowball method. Validity of the scale was assessed by correlating the obtained results with the AUDIT(Alcohol Use Disorder Identification Test), while reliability was assessed by internal consistency analysis.
Results. The presented analysis demonstrates high validity and reliability in most areas, which means that the PDS is a tool that can be used in clinical practice. Criterion validity was calculated by correlating PDS results with the 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’s alpha coefficients with the 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. The PDS 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 severity of the disorder and in monitoring changes in the treatment process.
