ABSTRACT

Introduction: the Environmental Stress Questionnaire is the latest version of a measuring instrument used for determining the degree of stress and stressors that affect adults during hospitalization in intensive care units. Its use for the classification of the phenomenon has been supported in English, Chinese, Basaha, Portuguese and Turkish, with facial validity, of content, construct and proven reliability. The literature does not have any Spanish version available.
Objective: to establish a Spanish equivalent, valid and reliable version of the Environmental Stress Questionnaire.
Methods: methodological quantitative study conducted from January 2014 to January 2015. Technical and back-translation was used for transcultural adaptation. The facial validity was calculated with the simple concordance index; the content validity, Lawshe modified index.
Results: the transcultural Spanish version of the Environmental Stress Questionnaire was produced. The facial validity determined by experts modified the title; linguistic quantifiers transformed nineteen items and deleted two. Content validity added three items and eliminated ten which were redundant. The facial validity set by patients ratified clarity, understanding, accuracy and form of the instrument. The scale has a four-factor solution with an explained variance of 32.248%, a Cronbach's alpha of 0.877, a Spearman coefficient of 0.811 and a Guttman coefficient of 0.810.
Conclusion: the scale of stressing factor experienced by patients in the intensive care unit is the validated Spanish version of the Environmental Stress Questionnaire, before using it routinely, it is recommended to continue with its refinements.
