Validity evidences of the buying impulsiveness scale in the Brazilian context

Abstract

The objective of this study was to obtain evidence of validity of an instrument to measure the tendency to buy impulsively. A version adapted to Brazil of a Buying Impulsiveness Scale was applied to 1296 Brazilians from all states of the federation, with a mean age of 35.8 years (SD = 12.8). The results indicated a scale with one-factor structure, just like the original instrument, with an adequate index of internal consistency. Positive correlations were found between impulse buying tendency, normative social influence, and traits of impulsiveness of the consumer. The instrument was also able to differentiate people who make shopping lists from those who do not do them, and people who prefer to go shopping alone from those who prefer to buy accompanied by someone else. The evidences found in the study provide support to the use of the instrument for the Brazilian context.
