For a scientist committed to empirical evaluation, it is important to show that materials can be helpful outside the context of a therapeutic relationship, so, generally speaking, we know that a book like this is likely to be helpful. Several of the specific components in this book have been tested, sometimes in a form very similar to the way you are contacting this material. For example, several studies evaluated the impact of short passages drawn nearly word for word from ACT materials (very similar to what you've read) that were recorded on audiotape, read aloud by a research assistant, or were presented to the participants to read. Typically, these studies focused on the ability of participants to tolerate distress of various kinds, such as gas-induced panic-like symptoms, extreme cold, extreme heat, or electric shock. A few studies looked at the distress produced by difficult or intrusive cognitions, or clinically relevant anxiety. Some were done with patients, others with normal populations. The specific ACT components that have been examined so far include defusion, acceptance, mind-fulness, and values. The techniques included exercises, metaphors, and rationales, including several that can be found in this book (e.g., word repetition, physicalizing, leaves on a stream, the quicksand metaphor, the Chinese finger trap metaphor, and so forth). Thus, it seems fair to say that it is known that at least some of what you've read can be helpful at least some of the time outside of the context of a therapeutic relationship, when presented in a form similar to the form in which you have contacted this material.
