Abstract
ObjectiveAdaptation and validation of the BTI-St© to assess the level of competence in brief tobacco intervention in general practitioners and nurses in Primary Health Care. DesignCross-sectional study of adaptation and psychometric validation of a criterion-referenced test. SettingPrimary Health Care. ParticipantsOne hundred fifty-five general practitioners and nurses working at Primary Health Care. InterventionsThree clinical scenarios were designed. Using an online platform, participants first viewed each scenario in which brief tobacco intervention was given. Health professional had to assess whether or not the scenarios were carried out in accordance with the 5A+5R model. Main measuresCompetence in brief tobacco intervention measured by the BTI-Prof©. ResultsResults related to reliability were obtained through Kuder-Richardson coefficient, being for scenario 1, 0.880, for scenario 2, 0.829, and for scenario 3, 0.826. The test–retest shows adequate temporal stability: intraclass correlation coefficient for scenario 1 0.857 (95% CI 0.734–0.923), p<0.0001, for scenario 2 0.829 (95% CI 0.676–0.909), p<0.001, and for scenario 3 0.869 (95% CI 0.76–0.928), p<0.0001. ConclusionsThe BTI-Prof© is a robust tool with adequate psychometric properties to assess competence in brief tobacco intervention in Primary Health Care general practitioners and nurses.
