Effectiveness of an Arabic CPIC-Based Pharmacogenomics Microlearning Program on Community Pharmacists' Clinical Decision-Making in Jordan

Inclusion Criteria: * Participants had to be licensed pharmacists working in a community pharmacy in Jordan * Participants had to be capable of comprehending the Arabic language * Participants have access to internet-enabled devices (smartphones, tablets, computers) * Participants give informed consent electronically and agree to take all assessments longitudinally (baseline, immediate post-intervention, and follow-up four weeks later). Exclusion Criteria: * Participants having an advanced postgraduate specialty or previous training in PGx (This criteria helps eliminate the problem of ceiling effect in order to evaluate the intervention as intended for a specific target audience: community pharmacists without advanced precision medicine training.) * Participants being involved in PGx research, curriculum development, and/or delivering PGx services * Participants providing incomplete baseline surveys * Participants withdrawing from the study before randomization. These exclusions were purposefully designed to mitigate baseline expertise bias and ensure the sample accurately reflects the broader, non-specialized community pharmacy workforce.
