Psychometric proprieties of the portuguese version of the frost multidimensional perfectionism scale

Abstract

Perfectionism is defined as the desire to achieve the highest standards of performance, in combination with unduly critical evaluations of one's performance. This study was designed to analyse the psychometric proprieties of the Portuguese version of the Frost Multidimensional Perfectionism Scale through confirmatory factor analysis in two different samples (calibration with 350 adolescent athletes and validation with 206 adolescent athletes). The confirmatory factor analysis suggested that after dropping items with low factor loadings, the six-factor model showed good fit (χ 2 = 292.83, B-S p < 0.001; χ 2 /d f = 1.693, PCFI = 0.79, PGFI = 0.70, CFI = 0.96, GFI = 0.93, RMSEA = 0.045). All constructs presented good internal consistency, convergent and discriminant validity. A multi-group analysis exposed the cross validity of the model. The correlations between perfectionism, fear of failure and sport anxiety measures revealed evidence of its concurrent validity, providing evidence for the proposed model. Overall, the results of the present study provided evidence for these instruments' validity and reliability, however further investigations are required. Resumen El perfeccionismo se define como el deseo de alcanzar altos modelos de rentabilidad asociado a evaluaciones críticas relativas a su rentabilidad. Este estudio tuvo por objetivo realizar un análisis psicométrico de la versión Portuguesa de la Escala Multidimensional de Perfeccionismo de Frost, en dos muestras diferentes (calibración con 350 atletas adolescentes y validación con 206 atletas adolescentes). El análisis factorial confirmatorio sugierió que después de dejar caer artículos con cargas bajas de factores, el modelo de seis factores mostró un buen ajuste (χ 2 = 292.83, B-S p < 0.001; χ 2 /d f = 1.693, PCFI = 0.79, PGFI = 0.70, CFI = 0.96, GFI = 0.93, RMSEA = 0.045). Las propiedades psicométricas del nuevo modelo han demostrado una buena consistencia interna, validad convergente y discriminante. El análisis multigrupos realizado ha comprobado la validad cruzada del modelo. Las correlaciones entre el perfeccionismo, el miedo a fallar y la ansiedad deportiva han revelado su validéz concurrente, proveyendo así evidencias de que el modelo propuesto es una herramienta válida para acceder al perfeccionismo en el contexto deportivo Portugués, sin embargo futuras investigaciones son necesarias.

The Spanish Version of the Sexual Opinion Survey (SOS-6): Evidence of Validity of a Short Version

“…The following criteria were taken into account to evaluate the multigroup CFA: CFI and TLI> .90 and RMSEA <.08 (Hu & Bentler, 1999;Manrique & Semenova, 2015;Wang & Wang, 2012), as well as the difference between the CFI comparative index values (Bentler, 1990). The difference between nested models was considered; therefore, if the CFI value was higher than .01 in favor of the model with fewer restrictions, the most restrictive model would be rejected (Cheung & Rensvold, 2002;Correia, Rosado, & Serpa, 2017). Finally, the invariance levels representing the relationship between observable variables and latent variables were analyzed (Milfont & Fischer, 2010).…”

“…It should also be noted that the PFAI, originally designed for North American sports, has been validated in different languages and countries, including the British [31], Spanish [7], Chinese [32], Portuguese [33,34,35], and Danish [36] contexts, and recently for Turkish [37] and Jordanian [38] conditions, as well as in education with Spanish secondary school students in physical education classes [39,40].…”

Multidimensional Models of Perfectionism and Procrastination: Seeking Determinants of Both

“…A multidimensional model for fear of failure has been recently created by Conroy, Willow, and Metzler [64], identifying five individual aspects of fear of failure: experiencing shame and embarrassment, devaluing one's self-esteem, having an uncertain future, important others losing interest, and upsetting important others. Several studies have linked all five fear of failure aspects to both parental expectations and parental criticisms [65,66].…”
