Validity and reliability of two instruments to assess adherence to treatment in burn patients
Abstract
Introduction: Therapeutic adherence constitutes one of the main problems of health interventions. One of the populations in which difficulties in adherence to treatment are evidenced is burn patients.
Objective: To determine the validity and reliability of two instruments for the evaluation of adherence to treatment and their influential dimensions in hospitalized burn patients.
Methods: From the quantitative approach, a cross-sectional study was conducted, in the period from January 2017 to December 2019. Adherence to treatment and influencing adherence to treatment were established as research variables. Expert judgment was used, the pilot test and finally the two questionnaires were applied to 90 burn patients.
Results: Both instruments proved to have content validity. The test-retest reliability of the instrument to evaluate therapeutic adherence was considerable and significant, while the internal consistency was acceptable. Reliability was very strong and consistency good in the instrument that evaluates the influencing dimensions in therapeutic adherence.
Conclusions: The two instruments developed for the evaluation of therapeutic adherence in hospitalized burn patients present content validity and reliability.
