||Previous work assessed inter-rater reliability of expert raters using six scales to estimate the intensity of literature-based mechanical exposures. The objectives of this study were to estimate the impact on the inter-rater reliability of using non-expert (NE) raters and to assess the validity of rating scales. Expert and non-expert (students with training in biomechanics) rated reports from published articles that described mechanical exposure into a set of common metrics. Seven-point scales were used to represent three dimensions of mechanical exposures at work: trunk posture; weight lifted or force exerted; spinal loading. Findings support using NE raters to estimate the intensity of literature-based mechanical exposure metrics using a common set of scales which can be applied across epidemiologic studies. One would need to average the ratings of at least five NE raters to have an acceptable level of reliability.
