Background. Evidence-based practice (EBP) and evidence-based clinical practice guidelines are becoming increasingly important in physical therapy. For the purpose of meeting the goals of designing, implementing, and evaluating strategies to facilitate the development of more EBP in primary care physical therapy, a valid and reliable questionnaire for measuring attitudes, knowledge, behavior, prerequisites, and barriers related to EBP and guidelines is needed. less thanbrgreater than less thanbrgreater thanObjective. The 3 objectives of this study were: (1) to translate and cross-culturally adapt a questionnaire to a Swedish primary care context for the purpose of measuring various aspects of EBP and guidelines in physical therapy, (2) to further develop the questionnaire to examine more aspects of guidelines, and (3) to test the validity and reliability of the adapted Swedish questionnaire. less thanbrgreater than less thanbrgreater thanDesign. This was an instrument development study with validity and reliability testing. less thanbrgreater than less thanbrgreater thanMethods. A previously used questionnaire about EBP was translated and cross-culturally adapted to a Swedish primary care physical therapy context. Additional items were constructed. A draft version was pilot tested for content validity (n=10), and a revised version was tested for test-retest reliability (n=42). The percentage of agreement between the 2 tests was analyzed. less thanbrgreater than less thanbrgreater thanResults. The development process resulted in a first questionnaire draft containing 48 items. The validation process resulted in a second draft with acceptable content validity and consisting of 38 items. The test-retest analysis showed that the median percentage of agreement was 67% (range=41%-81%). After removal or revision of items with poor agreement, the final questionnaire included 31 items. less thanbrgreater than less thanbrgreater thanLimitations.

The final translated and adapted questionnaire was determined to have good face and content validity and acceptable reliability for measuring self-reported attitudes, knowledge, behavior, prerequisites, and barriers related to EBP and guidelines among physical therapists in primary care settings.
