RESULTS The instruments most frequently used were single-item VAS and Biberoglu and Behrman pain score , while multidimensional inventories were used in few studies .
The results of clinical studies in CPP are more frequently based on one-dimensional measurements .
RATIONALE Many types of  pain assessment are available to research ers carrying out clinical trials in chronic pelvic pain ( CPP ) , ranging from a single-item scale to multidimensional inventories .
AIM Our objective was to investigate which assessment s of pain are more commonly used in clinical trials on CPP .
For Whom Does It Work? Moderators of the Effects of Written Emotional Disclosure in a Randomized Trial Among Women With Chronic Pelvic Pain
Objective Although written emotional disclosure has potential as a stress management intervention for people with health problems , the main ( group ) effects of disclosure in medical population s are limited . This study sought to identify individual difference moderators of the effects of written disclosure among women with chronic pelvic pain . Methods In a prospect i ve , r and omized trial , 48 women with chronic pelvic pain completed 3 individual difference measures and then wrote for 3 days about stressful consequences of their pain ( disclosure ) or positive events ( control ) .  Health status was assessed at baseline and 2 months after writing . Results Main effect group comparisons indicated that disclosure writing result ed in significantly lower evaluative pain intensity ratings than control writing at follow-up , but there were no main effects on other outcome variables ( sensory or affective pain , disability , affect ) . Three baseline individual difference measures , however , significantly moderated group effects . Compared with control writing , disclosure led to less disability among women with higher baseline ambivalence over emotional expression or higher catastrophizing , and to increased positive affect among women with higher baseline negative affect . Ambivalence , but not catastrophizing , was independent of negative affect in its moderation effect . Conclusion Although the main effects of writing about the stress of pelvic pain are limited , women with higher baseline ambivalence about emotional expression or negative affect appear to respond more positively to this intervention
