The main purposes of the present study were to evaluate: the psychometric properties of the Italian version of the General Decision-Making Style Inventory (GDMS); the relationship among decision-making styles, as proposed by GDMS, and thinking styles, assessed by Style of Learning and Thinking (SOLAT). The psychometric properties of GDMS were evaluated on a sample of 422 students, while 230 students also completed the Italian version of the SOLAT. The reliability of the GDMS scales (rational, intuitive, dependent, avoidant and spontaneous) appeared to be satisfactory with good internal consistency. The pattern of inter-correlation between the different styles was in line with the results reported by the literature. Confirmatory and Exploratory factor analyses showed that the hypothesized 5-factor model provided an acceptable fit for the data. Furthermore, the patterns of relationship between the decision-making styles and the SOLAT scales provide concurrent validity of the GDMS.

Abstract
The main purposes of the present study were to evaluate: the psychometric properties of the Italian version of the General Decision-Making Style Inventory (GDMS); the relationship among decision-making styles, as proposed by GDMS, and thinking styles, assessed by Style of Learning and Thinking (SOLAT). The psychometric properties of GDMS were evaluated on a sample of 422 students, while 230 students also completed the Italian version of the SOLAT. The reliability of the GDMS scales (rational, intuitive, dependent, avoidant and spontaneous) appeared to be satisfactory with good internal consistency. The pattern of inter-correlation between the different styles was in line with the results reported by the literature. Confirmatory and Exploratory factor analyses showed that the hypothesized 5-factor model provided an acceptable fit for the data. Furthermore, the patterns of relationship between the decision-making styles and the SOLAT scales provide concurrent validity of the GDMS.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
