The West Haven-Yale Multidimensional Pain Inventory (WHYMPI) was used for assessment of pain in these patients. For validation of this inventory the results were compared with those obtained from Brief Pain Inventory (BPI) Beck Depression Inventory (BDI) State Trait Anxiety Questionnaire and Enrich marriage inventory. Using Cronbach's alpha validity of the first section of WHYMPI was 0.86 the second section was 0.78 and the third section was 0.75. The Test-retest correlation was 0.95. Also the correlation of each individual section with the whole inventory was positive and significant.
