Validation of the Internet Gaming Disorder Scale - Short-Form (IGDS9-SF) in an Italian-speaking sample.

Background and aims The inclusion of Internet Gaming Disorder (IGD) in Section III of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders has increased the interest of researchers in the development of new standardized psychometric tools for the assessment of such a disorder. To date, the nine-item Internet Gaming Disorder Scale - Short-Form (IGDS9-SF) has only been validated in English, Portuguese, and Slovenian languages. Therefore, the aim of this investigation was to examine the psychometric properties of the IGDS9-SF in an Italian-speaking sample. Methods A total of 757 participants were recruited to the present study. Confirmatory factor analysis and multi-group analyses were applied to assess the construct validity. Reliability analyses comprised the average variance extracted, the standard error of measurement, and the factor determinacy coefficient. Convergent and criterion validities were established through the associations with other related constructs. The receiver operating characteristic curve analysis was used to determine an empirical cut-off point. Results Findings confirmed the single-factor structure of the instrument, its measurement invariance at the configural level, and the convergent and criterion validities. Satisfactory levels of reliability and a cut-off point of 21 were obtained. Discussion and conclusions The present study provides validity evidence for the use of the Italian version of the IGDS9-SF and may foster research into gaming addiction in the Italian context.

Factores motivacionales relacionados con la agresividad en las artes marciales / Motivational factors related to aggression within martial arts context / Factores motivacionais relacionados com a agressividade nas artes marciais

La finalidad del trabajo fue analizar un modelo de mediación en donde la orientación motivacional, la motivación autodeterminada y la deportividad eran factores predictivos de la agresividad. Practicantes de artes marciales italianos (N = 366; Medad = 29.53 años, DE = 9.107; Hombres = 325, Mujeres = 41) completaron un cuestionario para medir la orientación motivacional, la motivación autodeterminada, la deportividad y la agresividad. El path analysis confirmó el modelo hipotetizado: la motivación autodeterminada media la relación entre la orientación motivacional y deportivad y esta última media la relación entre la motivación y la agresividad. Los resultados sugieren que se debería intervenir sobre los factores motivacionales para prevenir la agresividad entre los atletas

This study was aimed at testing a meditational model in which goal orientation, self-determined motivation, and sportspersonship were predictive factors of aggressiveness. Italian martial artists (N = 366; Mage = 29.53, SD = 9.107; Men = 325, Female = 41) were asked to fill in a questionnaire assessing sport orientation, sport motivation, sportspersonship, and aggressiveness. The path analysis supported the hypothesized model: self-determined motivation mediates the relationship between motivational orientations and sportspersonhip, which in turn mediates the relationship between motivation and aggressiveness. The results suggest considering these motivational factors in order to plan interventions to prevent aggressiveness among athletes

finalidade do trabalho foi analisar um modelo de mediação no qual a orientação motivacional, a motivação auto-determinada e odesportivismo eram factores preditores da agressividade. Praticantes de artes marciais italianos (N = 366; Midade= 29.53 anos, DP= 9.107; Homens =325, Mulheres = 41) completaram um questionário para medir a orientação motivacional, a motivação auto-determinada, o desportivismo e aagressividade. A path analysis confirmou o modelo testado: a motivação auto-determinada medeia a relação entre a orientação motivacional e odesportivismo que por seu turno medeia a relação entre a motivação e a agressividade. Os resultados sugerem que se deveria intervir sobre os factoresmotivacionais para prevenir a agressividade entre os atletas
