Background: More than 20 years ago, the Drug and Drug Problems Perception Questionnaire (DDPPQ) was developed to examine healthcare providers' attitudes and perceptions towards individuals who use drugs. In alignment with recommended terminology respectful of this patient population, the 20-item measure was revised using person-centered language. Therefore, this study aimed to examine the psychometric properties of the person-centered DDPPQ (PC-DDPPQ) version among undergraduate nursing students.
Methods: Exploratory and confirmatory factor analyses were used to examine the PC-DDPPQ factor structure using a cross-sectional design. A convenience sample of 400 students from two nursing schools located in the Northeast and Mid-Atlantic regions of the US participated in the study. The sample (N = 400) was divided equally between the exploratory factor analysis (EFA) and the confirmatory factor analysis (CFA).
Results: After applying principal axis factoring (PAF) with oblique (Promax) rotation, the EFA yielded a five-factor, 20-item structure that explained 70.0% of the variance. The CFA revealed that the final model, derived from the EFA, which yielded a 19-item, five-factor structure adequately fit the data (Comparative Fit Index (CFI) = 0.959, the Tucker-Lewis Index (TLI) = 0.951 and Root Mean Square Error of Approximation (RMSEA) = 0.058).
Conclusions: Except for one item (item #14), the five-factor structure aligned with the original 20-item version. This study contributes to promoting the use of a more appropriate and less stigmatizing language among healthcare providers working with patients who use drugs.
