The Hewitt and Flett Multidimensional Perfectionism Scale (H&F-MPS) is one of the most used measures of perfectionism. Their 45-items evaluate self-Oriented (SOP), Self-Prescribed (SPP), and Other Oriented (OOP) perfectionism.

To study the internal consistency and convergent validity of the H&F-MSP13.

One hundred and ninety-two university students (78.1% females), aged 19.74 years (sd=2.10; range: 17–28) completed the Portuguese versions of H&F-MPS (Soares et al., 2003) and of Frost et al. MPS (F-MPS) (Amaral et al., 2013). Thirteen items were selected from the Portuguese version of the H&F-MPS, based on their loading in the factor (0.60 and over) (Soares et al., 2003).

The H&FMPS13 revealed good internal consistency (α=0.816). The corrected item-total subscale Spearman's correlations were high (from 0.418 to 0.820). The principal component analysis with factors varimax rotation produced three factors, which revealed acceptable/good internal consistency (SOP: explained variance/EV=35.4%, α=.900; SPP: EV=16.3%, α=0.695; OOP: EV=10.8%, α=0.709). The correlations between the H&F-MSP13 scores and the matching scores of the H&F-MPS were high (from r=0.745 to r=0.945, all P<.01), suggesting that both scales measure similarly the constructs. The H&F-MSP13 and the H&F-MPS total scores demonstrate good convergent validity with the total score of F-MPS, as indicated by the correlations (r=0.581/r=0.636, respectively). The correlations similarities between the H&F-MSP13 and H&F-MSP dimensions and the F-MPS dimensions and total scores were also considerable.

The H&F-MSP13 is a valid instrument to measure perfectionism that reveals convergent validity with the F-MPS, retaining the adequate psychometric properties of the H&F-MPS and its administration is less time consuming.
