Table 2.
Number of anatomical pain regions, workload, and psychosocial work stressors over time.
| Variables | Baseline | Follow-Up | ||
|---|---|---|---|---|
| n | Mean (SD) | n | Mean (SD) | |
| Number of anatomical regions with pain (ARP; range 0–23) | 11,386 | 1.7 (2.8) | 11,386 | 1.8 (2.8) |
| Workload | ||||
| Mechanical exposure index (MEI; range 10–30) | 9140 | 15.1 (4.0) | 9121 | 14.9 (4.1) |
| Physical exposure index (PHYI; range 6–18) | 9544 | 9.8 (3.0) | 9486 | 9.7 (3.1) |
| Psychosocial work stressors | ||||
| Job demands (mean JCQ; range 1–4) | 10,376 | 2.5 (0.6) | 10,294 | 2.5 (0.6) |
| Job control (mean JCQ; range 1–4) | 10,388 | 3.0 (0.5) | 10,299 | 3.0 (0.5) |
| Job support (mean JCQ; range 1–4) | 10,281 | 3.2 (0.5) | 10,237 | 3.2 (0.5) |
ARP = anatomical regions with pain; JCQ = Job Content Questionnaire; MEI = Mechanical exposure index; PHYI = Physical exposure index; SD = standard deviation; n = number of answers. Note: Higher scores on the scales indicate more extent of pain on the body, high workload, high demands, better control, and better support.
