Design outcomes

| Measure | Time frame |

| The main study parameter will be the feasibility of the counterconditioning intervention. This will be done by looking at the drop-out rate, by measuring participant*s satisfaction with the intervention; by examing what, according to the participants, is causing the possible increase and reduction of experimentally evoked pressure pain in the test phase of (counter)conditioning (e.g., the TENS device, the placebo or nocebo effect); by exploring the amount of experimentally-evoked pressure pain reported during the test phase of counterconditioning, whether this reduces over time, as well as the speed of this reduction. | — |
