The MPFI-24 is an inventory composed of 24 items designed to measure psychological flexibility and inflexibility. The 24 items are assessed on a six-point scale ranging from never true (1) to always true (6). This abbreviated version assesses psychological flexibility (first 12 items) and psychological inflexibility (last 12 items). Each of these composite indices (PF and PI) encompasses six factors corresponding to the Hexaflex model of ACT.
The confirmatory factor analysis of the Portuguese version of MPFI-24 supported a two-factor higher-order model with six psychological flexibility (PF) factors and six psychological inflexibility (PI) factors. The MPFI-24 revealed good reliability (alpha > .70) and test-retest reliability.
