Abstract
The current study examined the effects of acceptance of thoughts, mindful awareness of breathing, and spontaneous coping on both pain tolerance and pain threshold during a cold pressor task. Eligible participants (N = 58), 16 males and 42 females (M age = 29.31, SD = 11.21), were randomized into three groups and completed two cold pressor trials. The first cold pressor trial formed a baseline for all three groups. The acceptance of thoughts and mindfulness of breathing groups listened to recorded instructions and then completed a second administration of the cold pressor task. The spontaneous coping group completed the cold pressor task twice with instructions to select their own coping style. Multilevel linear modeling showed significant group differences in pain tolerance. The acceptance of thoughts and mindfulness of breathing conditions resulted in significantly higher pain tolerance in post hoc analysis than spontaneous coping. Results were interpreted to be consistent with Acceptance and Commitment Therapy. Further examination of the effects of ACT processes on experimentally induced pain tolerance is needed.

Appendix 1: Acceptance Rationale
When we are in pain, there are a number of different ways in which we can think about it. One way of thinking about pain is to accept that we are in pain. Here is an example of an “acceptance” way of thinking about pain: I try to accept that I am in pain. I do this by disconnecting my evaluations about the pain from the pain itself. For example, if I have a thought like, “I can’t stand this pain,” I can accept that thought and notice that this is a thought that doesn’t need to prevent me from continuing on. If instead I try and control my thoughts by imagining that the pain isn’t there, I find that I end up thinking about my pain even more. When I accept thoughts, I can notice them, but I don’t allow them to control my behavior. I accept my thoughts and my feelings as they are, without trying to control them or without trying to push them away. I can stop trying to control the pain since this may be unproductive; instead, I try not to ignore my pain, and I don’t try to push thoughts away. I try to accept that the pain doesn’t mean I can’t continue on. What I need to do is accept my thoughts as they are.
Acceptance Instructions for the Pain Task
Thoughts and feelings do not cause you to do things. Therefore, if you have thoughts such as “I can’t stand this pain,” you do not have to let the thought control your actions. So, you are able to feel pain and still keep your hands in the cold water.
Appendix 2: Mindfulness Rationale
This exercise is called “awareness of breathing.” The exercise is brief and is an introduction to mindfulness practice. First, close your eyes, and let your awareness shift to your body in the chair. Now I would like you to focus your attention on your breathing. First of all, allow your attention to notice a deep slow breath, in and out. And again take a deep slow breath in and out, and on your next breath, pay attention to the feeling of the air coming into your body through your nostrils. Just feel the sensation of the air coming in and then going out of your body, and notice if you can, the movement of your belly as you breathe, and notice the movement of your ribs as you inhale and exhale. Notice which parts of your body move as you breathe. So as you sit there, continue to breathe in and out and let your awareness rest on this process of breathing in and breathing out. Keep your awareness on the sensations and feelings of just breathing. And as you continue to notice the breathing, notice any physical sensations in your body. See if you can notice the physical sensations of your body in the chair and your feet on the floor. Now, bringing your awareness again back to your breathing, see if you can follow the air as it goes all the way in through your nostrils down into your lungs. Notice the rise and fall of your stomach, the expanding and collapsing of your ribs, and any other movement in your body as you breathe. And if your mind has anything to say about this process, if it wants to draw you away to thinking about other things, just acknowledge your mind for that and bring your attention back to your breathing. Every time your mind runs away to thinking about other things, just simply bring your attention back to your breathing; there’s no need to force it. Just gently bring your attention back each time to your breathing. Now with mindfulness practice, you can choose to use mindfulness breathing by bringing your awareness to your breathing at any time.
Mindfulness Instructions for the Pain Task
In the cold pressor task that you’ve been doing, you can choose to use mindfulness of your breath to bring your attention to your breathing as you perform the task.
