Development of a brief stigma and perceptions questionnaire for pharmacists: An exploratory factor analysis approach in New York state counties enrolled in the healing communities study

Introduction

Little is known about how pharmacists' attitudes and stigma toward naloxone and Medication for opioid use disorder (MOUD) influence effective linkage to treatment. We examine the psychometrics of a new Pharmacist Opioid Use Disorder Perceptions Questionnaire (P-OUDP-Q), a multidimensional measure to examine pharmacists' stigma and perceptions related to MOUD in the New York State (NYS) site of the HEALing Communities Study.

Methods

The study recruited a sample of 324 pharmacists from 16 counties in NYS between January and June 2022. A 74-item questionnaire assessed pharmacists' familiarity with opioid-related medications, protocols, policies and attitudes regarding their role, confidence, and beliefs centered around delivery of MOUD and naloxone in the community. Exploratory factor analysis assessed individual and community-level factors associated with four underlying constructs. Factor scores were compared across the demographic predictors. Variables factor loadings <0.4 were eliminated from the factor analysis and the process was reiterated.

Results

Eighty-six percent (n = 280) of the pharmacists were white. A little over half, 57 % (n = 186), were female, 35 % (n = 113) were 30–35 years old. The mean number of years practicing (SD) was 18 (SD: 13). Exploratory factor analysis identified four underlying constructs: (1) practice confidence, (2) practice familiarity, (3) practice attitudes, and (4) methadone attitudes. Statistically significant (p < .05) mean factor scale score differences by race were observed for practice familiarity (white reporting higher than non-white); by pharmacy size for practice familiarity (across all groups; non-significant Tukey post-hoc) and practice attitudes (hospital/clinic greater than big chain pharmacies); by gender (males greater than females) for practice familiarity and methadone attitudes; by poverty quartile for practice attitudes (lowest less than highest quartile); and urban versus rural pharmacist county setting for practice familiarity (rural greater than urban).

Conclusions

Findings show the P-OUDP-Q is a concise measure of pharmacists' perceptions of their role in dispensing MOUD and naloxone, including distinct “stigma” dimensions, which is valuable for use with pharmacists in communities highly impacted by the opioid epidemic. The development and validation of a reliable measure to assess pharmacists' perceptions of stigma and barriers represents a valuable contribution to the field, to inform the design/implementation of targeted interventions and support systems.
