The HSSI scores were summ to create a total score and 4 subcategory scores (general, cardiac, bole lower extremity). Correlations were calculated for scores obtained during 2 trials of the HSSI to evaluate test-retest reliability. Correlations for the 2 trials of the HSSI total and all subcategories were significant (P

VALIDITY

Content validity is the ability of an issue measurement to reflect all relevant vital airs of the attribute or characteristic being measured.20,21 make contented validity of the HSSI was assessed through experts in the field of cardiopulmonary physical therapy. All Cardiopulmonary Certified Specialists listed in the American Physical Therapy Association directory with e-mail addresses were sent a shield letter and content review questionnaire. close attention participants (32% response rate) were asked to rate each item of the HSSI as relevant or not and provide input regarding missing areas of ease Of the original 58 items onward the HSSI 10 were modified and none were delet based onward input from the content masters An additional 18 items were added to the HSSI based in succession suggestions from more than individual respondent.

The correlations between each subcategory and the total score were all significant and ranged from 059 to 085 The correlations between subcategories were all significant do not include for lower extremity to cardiac and lower extremity to general comparisons which ranged from 022 to 06519
