The present study is a pilot study that aims to evaluate the feasibility, validity, and preliminary efficacy of three psychological treatment components for pain after breast cancer, which will be evaluated in a larger trial following completion of the present pilot study.

The present pilot study is a precursor for a following larger trial and aims to evaluate the i) feasibility, ii) validity, and iii) preliminary efficacy of the three treatment components that will be further investigated in a subsequent larger trial. The present pilot study will employ the same design as will be used in the subsequent larger trial, namely the Multiphase Optimization Strategy (MOST). Specifically, in the subsequent larger trial, MOST will be used to evaluate the efficacy and change processes of three psychological treatment components selected from so-called "third wave" cognitive therapies (CTs), which have been shown to be efficacious in the treatment of pain after breast cancer.

The overall hypothesis is that the selected third wave CT components will target key maintaining psychological factors in pain, thus leading to reductions in the primary outcomes of pain intensity and -interference. Specifically, we hypothesize that:

1. Mindful attention practices will increase attentional control (i.e., the ability to intentionally focus and intentionally shift one's attention), thereby reducing pain hypervigilance, leading to reductions in pain intensity and -interference.
2. Decentering practices will reduce fusion with thoughts (i.e., getting caught up in one's thoughts and acting automatically in response to thoughts), thereby reducing pain catastrophizing, leading to reductions in pain intensity and -interference.
3. Values and committed action (i.e., behavior linked to values and goals) will increase acceptance of discomfort and reduce avoidant behavior, leading to reductions in pain intensity and -interference.

The study uses a 2\^3 factorial design, randomizing participants to 8 experimental conditions

Participants will be invited to participate in a 30-minutes semi-structured individual interview 10-14 days after their last session. The interview serves to support the validation of the treatment components and to provide in-depth knowledge about the participants' experiences through their qualitative comments.

The present study aims to optimize psychological treatment for pain after breast cancer by identifying active treatment components. Specifically, a factorial design will be used to evaluate the efficacy and change processes of three psychological treatment components, which have been shown to be efficacious in the treatment of pain after breast cancer.

There is a need for optimization of psychological treatment of pain after breast cancer. Optimization relies on knowledge about the active components of existing treatments. Guided by the Multiphase Optimization Strategy (MOST), the present study aims to address this challenge by identifying active contemporary cognitive behavioral therapy components for breast cancer-related pain. Consistent with the Optimization phase of the MOST framework, a full factorial design will be used to evaluate the efficacy and change processes of three selected treatment components.The overall hypothesis is that the three components will target key maintaining psychological factors in pain, thus leading to reductions in the primary outcomes of pain intensity and -interference. The treatment components and their hypothesized mechanisms of action are as follows:

1. Mindful attention practices will increase attentional control (i.e., the ability to intentionally focus and intentionally shift one's attention), thereby reducing pain hypervigilance, leading to reductions in pain intensity and -interference.
2. Decentering practices will reduce fusion with thoughts (i.e., getting caught up in one's thoughts, feelings and inner experiences), thereby reducing pain catastrophizing, leading to reductions in pain intensity and -interference.
3. Values and committed action (i.e., behavior congruent with one's values) will increase acceptance of discomfort and reduce avoidant behavior, leading to reductions in pain intensity and -interference.

The study uses a 2\^3 factorial design, randomizing participants to 8 experimental conditions. The seven active conditions consist of one, two, or three different treatment components. Participants receiving two or three treatment components will be randomized to receive them in different order.
