Evidence of validity and reliability of an Impulsivity Scale in adolescents from Ecuador

Abstract:

Objective: To identify the evidence of validity and reliability of internal consistency of the Plutchik Impulsivity Scale in a sample of adolescents from Ecuador. Method: Instrumental or psychometric study in which the factorial structure of the scale, the validity of the relationship with other variables and the reliability of internal consistency are analyzed. Participants: 770 adolescents (57.7% men and 42.3% women) aged between 12 and 18 years. They are students from educational centers in three cities in Ecuador distributed between Basic General Education (33.8%) and Baccalaureate (66.2%). Results: There is evidence of validity from a four-dimensional structural model according to the original postulate of the measure. Furthermore, in terms of the validity of the relationship with other variables, the Plutchik scale converges with the Barratt Impulsivity Scale. Finally, the internal consistency of the scale scores is adequate. Conclusion: The factorial adjustment model of the scale is adapted to the adolescent sample, so the interpretation of the items is carried out based on the original criterion of the measure, ensuring its use and its interpretative capacity.
