Survey Outcome Scoring

Outcome Description Measure Frequency Scale Code
Annual Back Symptom Frequency > 0 Measures whether there was any workerreported back pain [every day for a week (7 days) or more) in the past 12 months] on the modified Nordic assessment survey modules. Baseline, 1st and 2nd annual 0 to 1 SUM all “1s” that appear in H4_113
Nass-Pain Frequency > 0 Measures whether there was any workerreported back pain in the past week on the Nass-Pain survey modules. Baseline, every 3 months 0 to 1 If abs(Nass-Pain Severity- 16.666) > .1 then Nass-Pain Severity = 1; else NassPain Severity = 0
Nass-Pain Severity Measures the level of worker-reported back pain in the past week on the NassPain survey modules. Baseline, every 3 months 16.7 to 100 Sum H1_1, H1_2, H1_9, H1_10, H1_11, H1_12, H1_13, H1_14, H1_15, H1_16, H1_17, divide total by 66, multiply by 100
Nass-Neuro Frequency > 0 Measures whether there was any workerreported back pain in the past week on the Nass-Neuro survey modules. Baseline, every 3 months 0 to 1 If abs(Nass-Neuro Severity - 16.666) > .1 then Nass-Neuro Severity = 1; else Nass-Neuro Severity0 = 0
Nass-Neuro Severity Measures the level of worker-reported back pain in the past week on the NassNeuro survey modules. Baseline, every 3 months 16.7 to 100 Sum H1_3, H1_4, H1_5, H1_6, H1_7, H1_8, divide total by 36, multiply by 100
Annual Upper Extremity Symptom Frequency > 0 Measures whether there was any workerreported upper extremity pain [more than 3 times or lasting a week (7 days) or longer in the past 12 months] on the modified Nordic assessment survey modules. Baseline, 1st and 2nd annual 0 to 5 SUM all “1s” that appear in H4_102, H4_104, H4_107, H4_110
DASH-Disability Frequency > 0 Measures whether there was any workerreported upper extremity pain in the last week on the DASH-Disability survey modules. Baseline, every 3 months 0 to 1 If abs(DASH-Disability Severity - 0) > .1 then DASH-Disability Severity = 1; else DASH-Disability Severity = 0
DASH-Disability Severity Measures the level of worker-reported upper extremity pain in the last week on the DASH-Disability survey modules. Baseline, every 3 months 0 to 100 Sum 018_H2 to 028_H2 then average, producing a score out of five. This value is then transformed to a score out of 100 by subtracting one and multiplying by 25
DASH-Work Frequency > 0 Measures whether there was any worker-reported upper extremity pain in the last week on the DASH-Work survey modules. Baseline, every 3 months 0 to 1 If abs(DASH-Work Severity - 0) > .1 then DASH-Work Severity = 1; else DASH-Work Severity = 0
DASH-Work Severity Measures the level of worker-reported upper extremity pain in the last week on the DASH-Work survey modules. Baseline, every 3 months 0 to 100 Sum 030_H2W to 033_H2W then average, producing a score out of five. This value is then transformed to a score out of 100 by subtracting one and multiplying by 25
Any Safety Events Frequency > 0 Measures whether there were any worker-reported safety related incidents at work within the last 3 months. Baseline, every 3 months 0 to 1 SUM all “1s” that appear in 047_H3B
Material Handling Task-related Safety Events Frequency > 0 Measures whether there were any worker-reported safety related incidents at work associated with specific material handling tasks within the last 3 months. Baseline, every 3 months 0 to 3 SUM all “1s” that appear in (048_H3B; 053_H3B; 058_H3B)
