Abstract:Two studies were conducted to adapt the Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS) to the Italian context. Results suggest that the BPNSFS can be considered a promising instrument in the context of SDT-based research for investigating satisfaction and frustration of the three basic needs in Italy.http://mc.manuscriptcentral.com/mecd Measurement and Evaluation in Counseling and Development
Psychometric Evaluation of the Basic Psychological Need Satisfaction and Frustration
Scale (BPNSFS) in Italy SummaryThe purpose of the present multistudy report was to adapt the Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS) to the Italian context. Two studies were conducted.In Study 1, we investigated the dimensionality, reliability, convergent and discriminant validity of the instrument in a sample of 544 participants (Males = 41%) aged from 16 to 35 years. In Study 2, we replicated the results concerning dimensionality in an independent sample of 502 participants (Males = 42%) aged from 16 to 35 years. Furthermore, we analyzed measurement invariance across gender. Results of both studies showed that comparing a series of competitive factorial models, the six-factor (6-factor) model had the best fit to the data, assessing six different but related dimensions: Autonomy Satisfaction, Autonomy Frustration, Relatedness Satisfaction, Relatedness Frustration, Competence Satisfaction, and Competence Frustration.Moreover, the reliability, convergent and discriminant validity may be considered adequate.Finally, the BPNSFS showed to be invariant across gender. In sum, the BPNSFS can be considered a promising instrument in the context of SDT-based research for investigating satisfaction and frustration of the three basic needs in Italy. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 F o r P e e r R e v i e w Italian Psychometric Evaluation of BPNSFS 2 Self-determination theory (SDT; Deci & Ryan, 1985; Ryan & Deci, 2002) has become a popular framework for examining motivational issues in several contexts (e.g., Costa, Gugliandolo, Barberis, & Larcan, 2014; Ng et al., 2012;Ryan & Deci, 2013;Soenens & Vansteenkiste, 2010). This is not surprising given that the approach to human development proposed within SDT accounts for the nature and function of motivation in conjunction with the psychological foundations from which motives develop. According to Ryan and Deci (2002), motivation varies along a regulatory continuum ranging from more controlled to fully selfdetermined processes, with the latter nurturing positive consequences such as task persistence and eudemonic well-being.Within SDT, a critical issue in the effects of motivation concerns the degree to which people are able to satisfy three universal, innate, and nonhierarchical psychological needs, namely, autonomy, relatedness, and competence.
