Concurrent validity of questions on arm, shoulder and neck symptoms of the RSI QuickScan

Purpose: The objective was to determine the concurrent validity of questions on arm, shoulder and neck symptoms of an Internet-based questionnaire. In addition, the inter-observer reliability of physical examinations by occupational physicians was investigated. Methods: A total of 160 employees of a Dutch occupational health service were approached, of which 106 participated. Right after the assessment of arm, shoulder and neck symptoms using a self-administered questionnaire, each participant was examined by two occupational physicians. The presence of symptoms in the past 7 days was compared to the physical examinations. The participation of two occupational physicians allowed us to study also the inter-observer reliability. Results: Overall, the concurrent validity of the symptom questions of the questionnaire can be defined as poor to moderate with κ values between 0.16 and 0.53. Detecting the presence of symptoms (

The influence of psychosocial work characteristics on the need for recovery from work: a prospective study among office workers

Purpose: To investigate the influence of high job demands, low job control, and high social support on need for recovery (NFR) among computer workers. Methods: Data was obtained from a longitudinal cohort study, including 5 consecutive measurements, with an in-between period of 6 months. General estimating equations analyses were performed to assess the risk for high NFR 6 months later. Odds ratios (ORs) for high NFR were calculated for high job demands, low job control and low social support, separately. Likewise, ORs were calculated for combinations of job demands and job control, as well as for combinations of job demands, job control and social support. Results: High job demands resulted in an increased risk for high NFR 6 months later, particularly in older workers. Low social support showed also an increased risk for future high NFR, but this was not the case for low job control. Furthermore, a combination of high job demands and low job control, as well as a combination of high job demands, low job control and low social support demonstrated an increased risk for future high NFR where older workers showed higher risks. Conclusion: This study demonstrated that adverse psychosocial work characteristics predicted future NFR among computer workers. © 2013 Springer-Verlag Berlin Heidelberg

Internal consistency, test-retest reliability and concurrent validity of a questionnaire on work-related exposure related to arm, shoulder and neck symptoms in computer workers

The aim of this study was to determine the internal consistency, test-retest reliability and concurrent validity of the RSI QuickScan, a newly developed questionnaire that aims to identify the presumed risk factors for neck, shoulder and arm symptoms in a population of computer workers. The internal consistency was calculated using item analysis. The test-retest reliability and concurrent validity were analysed by calculating the percentage of agreement, Cohen's Kappa and the Ppositive and Pnegative. The concurrent validity was also tested by comparing the results from the new questionnaire with those from the original questionnaires that the current questionnaire was based on, on-site expert observations and direct measurements. The results indicate that the RSI QuickScan is a measurement tool with acceptable internal consistency, reliability and concurrent validity. The questionnaire can be used as a means to rapidly collect data on a large population of office workers and at low cost. © 2009 Taylor & Francis
