Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Physical activity (leisure), which is the primary outcome, will be assessed at baseline (T0) and follow-up (T2, T3) assessments using self-reports (i.e., IPAQ long, Craig et al., 2003; Wanner et al., 2016), and during the 14-days intensive study period, using accelerometers (i.e., Move 4 activity sensors). | — |
Secondary
| Measure | Time frame |
|---|---|
| Pain intensity, which is the secondary outcome, will be assessed at baseline (T0) and follow-ups (T2, T3) using the German version of the Chronic Pain Grade Questionnaire (CPG, von Korff et al., 1992; Klasen et al., 2004). For the ambulatory assessment, pain intensity will be assessed with a single item based on the CPG questionnaire. Subjective health with regard to participants’ lower back (i.e., back health), which is an additional secondary outcome, will be assessed at baseline (T0) and follow-ups (T2, T3) using an adapted item 1 from the Short-Form-Health-Survey-12 (SF-12, Morfeld, Kirchberger, & Bullinger, 2011). For the ambulatory assessment, back health will be assessed with a single item based on the adapted SF-12 item. Additionally, theory-based psychological resources and risk factors as proposed in the Health Action Process Approach (HAPA, Schwarzer, 2008) and the Fear-Avoidance Model (Lethem et al., 1983) will be examined in the context of physical activity. In addition to physical activity, medication intake will be assessed. | — |
