A new study conducted by researchers at The Ohio State University College of Optometry has found a simple stress rating scale is a valid and useful tool for evaluating the connection between stress and progressive vision loss from age-related macular degeneration (AMD).
In their study, researchers reportedly used the Perceived Stress Scale (PSS) to determine how well it measures perceived stress in patients with vision loss due to AMD. They reportedly found nine of the 10 questions normally used with the PSS performed well with the patient group studied. Researchers believe an easy-to-administer questionnaire such as the PSS is important for use with AMD patient given the evidence for increased rates of psychological symptoms in the population.
The study was recently published in Optometry and Vision Science, the official journal of the American Academy of Optometry.
