Table 5 Stepwise linear regression model estimating predictors of the frequency of meeting the “Combined” or “Neither” guideline during follow-up (n = 245)

From: Patterns and predictors of exercise behavior during 24 months of follow-up after a supervised exercise program during breast cancer chemotherapy

  Number of Combined (0–3)  
Step/predictors Unstandardized B (95% CI) Standardized β p
1. Upper body strength 0.02 (0.01 to 0.04) 0.19 0.003
2. TPB Motivation 0.23 (0.07 to 0.40) 0.17 0.006
3. Lower body endurance 0.00 (0.00 to 0.06) 0.14 0.030
  Number of Neither (0–3)  
  Unstandardized B (95% CI) Standardized β p
1. VO2peak −0.03 (−0.05 to −0.01) −0.20 0.001
2. TPB Difficulty a 0.22 (0.11 to 0.34) 0.22 < 0.001
3. Lower body strength −0.01 (− 0.01 to − 0.00) −0.21 0.001
4. Site (Edmonton vs. Ottawa/Vancouver) −0.33 (− 0.58 to − 0.08) −0.16 0.009
  1. TPB = theory of planned behavior
  2. aHigh score indicates higher difficulty in exercise
