Pain assessment is a complex task often hindered by subjectivity, an overabundance of measurement options, and communication barriers. Research has focused on psychosocial factors that affect pain assessment as well as the need for a more concise method by which to measure pain. This study explored a previously proposed method of pain assessment involving corneal drying, deemed the Blink Test, as a potential method of determining individual pain tolerance. A correlational analysis was used to determine the usefulness of the Blink Test by comparing how long individuals could keep their eyes open with their performance on the Cold Pressor Test, a previously validated pain tool only used in research. No significant correlations were found between performances on the Blink Test with those on the Cold Pressor Test, suggesting that it is not a useful pain assessment. Further, scores on a measure of hope were collected to explore previous research connecting the pain experience to psychological factors.
