   PDI at 12 months follow-up
Model Predictors at baseline n = 73 B β 95% CI for B p-value R2
1 PDI 0.85 -0.87 0.67 to 1.04 <.001 .69
Pain Intensity -0.28 -0.05 -1.28 to 0.73 .58
SES -0.03 -0.05 -0.10 to 0.05 .50
TSK -0.10 -0.06 -0.34 to 0.147 .43
CAT 0.12 0.08 -0.11 to 0.35 .30
IES -0.12 -0.12 -0.28 to 0.04 .15

  1. Note:
  2. PDI = Pain Disability Index (0–70), low scores indicate low disability.
  3. Pain intensity (3 items 0–10), low scores indicate low pain intensity, control (1 item 0–10), low scores indicate low control.
  4. SES = Self-Efficacy Scale (0–200), low scores indicate low efficacy expectations.
  5. TSK = The Tampa Scale of Kinesiphobia (17–68), low scores indicate low fear.
  6. CAT = The Coping Strategies Questionnaire (0–36). High scores indicate higher frequency of catastrophic thinking.
  7. IES = Impact of Event Scale (0–75). High scores indicate severe symptoms.
