Considerable research has been conducted on how interrater agreement (IRA) should be established before data can be aggregated from the individual rater level to the organization level in survey research. However, little is known about how researchers should treat the observations with low IRA values fail to meet the suggested standard. We seek to answer this question by investigating the impact of two factors (the relationship strength and the overall IRA level of a sample) on the IRA decision. Using both real data from a service industry and simulated data, we find that both factors affect whether a researcher should include or exclude observations with low IRA values. Based on the results, practical guidelines on when to use the entire sample are offered. 展开更多

AIM To investigate the inter-and intra-rater reliability of the vertebral fracture classifications used in the Swedish fracture register.METHODS Radiological images of consecutive patients with cervical spine fractures(n = 50)were classified by 5 raters with different experience levels at two occasions. An identical process was performed with thoracolumbar fractures(n = 50). Cohen's kappa was used to calculate the inter-and intra-rater reliability.RESULTS The mean kappa coefficient for inter-rater reliability ranged between 0.54 and0.79 for the cervical fracture classifications, between 0.51 and 0.72 for the thoracolumbar classifications(overall and for different sub classifications), and between 0.65 and 0.77 for the presence or absence of signs of ankylosing disorder in the fracture area. The mean kappa coefficient for intra-rater reliability ranged between 0.58 and 0.80 for the cervical fracture classifications, between 0.46 and0.68 for the thoracolumbar fracture classifications(overall and for different sub classifications) and between 0.79 and 0.81 for the presence or absence of signs of ankylosing disorder in the fracture area.CONCLUSION The classifications used in the Swedish fracture register for vertebral fractures have an acceptable inter-and intra-rater reliability with a moderate strength of agreement. 展开更多
