Failures in regret anticipation undermine regret avoidance, increasing regret frequency and ultimately the risk of regret-related problems. The Regret Anticipation Failures Scale (RAFS; Schmidt and Linden, 2011) was developed to evaluate interindividual differences in regret anticipation.

To investigate the psychometric properties of the RAFS Portuguese version.

A community sample composed of 108 university students and 79 employees (78.1% females; mean age = 33.16 ± 13.175; range: 17–62) answered the Portuguese preliminary version of the RAFS. To study the temporal stability, 31 participants (83.9% females; mean age = 26.54 ± 18.761) answered the RAFS again after approximately 6 weeks.

The RAFS Cronbach alpha was “very good” (a = 0.81). All the items presented significant correlations with the total (excluding the item; > 0.20); only item 2 (Even when I’m stressed, I can foresee the regrets that certain behaviors could evoke in me) had the effect of lowering the internal consistency if deleted. The test-retest correlation coefficient was high, positive and significant (0.61; P < 0.001); there was not significant difference between test and re-test scores [14.26 ± 5.170 vs. 13.06 ± 4.761, t (30) = 1.532, P = 0.136]. Following Kaiser and Cattel Scree Plot criteria, only one factor was extracted, meaning that the scale is unidimensional.

The Portuguese version of RAFS has good reliability and construct validity. It could be very useful both in clinical and research contexts, namely in an ongoing project on the relationship between regret, personality and psychological distress.
