When scientists write up their research findings, they will attempt to have their manuscripts published in scientific journals. It’s good practice for researchers to provide the psychometric properties (e.g., reliability or validity measures) for the measures they report in the Methods section of their paper. Here are some research papers by faculty members here in Memorial University’s Psychology Department.
