Research in Deliberate Self Harm, Acceptance, avoidance, mindfullness and psychological flexibility

Hello List Community,
My name is Gillian Maddock and I am a D Clin Psych canditate at the University of Newcastle, NSW Australia. I am aware that some questions may have been asked before, however I have not been able to pinpoint the information I need. I hope these questions are o.k. to ask.

Following the thesis put forward by Chapman, Gratz & Brown (2006) concerning deliberate self-harm (DSH) being a function of experiential avoidance (independent of clinical diagnostic categories) I am planning research to discriminate between levels of acceptance, avoidance, mindfullness and psychological flexibility in clinical psychiatric populations who engage in self harm and those who do not. I have a number of questions:

1. I have not been able to locate research looking at the specific measurement of avoidance or acceptance or mindfulness or psychological flexibility in relation to: a) DSH b) b) DSH not in particular reference to Borderline personality disorder. Does anyone know of any?

2. I am looking at the AAQ2 as a measure of avoidance and acceptance. Thanks to Frank Bond's response to a request for information, I have read that the AAQ-2 rests on a one factor solution and I assume this one factor specifically refers to the theoretical concept of psychological flexibility?

Can anyone help me work out how measures of avoidance and acceptance fit into the AAQ-2. Are they built into the psychological flexibility factor? Should they be measured separately with another instrument? Would it be valid to identify the acceptance and avoidance factors based on face validity or does that mess with the psychometric properties of the instrument?

Any assistance would be greatly appreciated, and I apologise for any repetition in terms of previous list serve discussion.

With Best Wishes
Gillian
