The H&F Multidimensional Perfectionism Scale 13 (H&F MSP13) Construct and convergent validity
Introduction 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. Objectives To study the internal consistency and convergent validity of the H&F MSP13. Methods 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) Results The H&FMPS13 revealed good internal consistency (a 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% a .900; SPP: EV 16.3% a 0.695; OOP: EV 10.8% a 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. Conclusions 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.
