Psychometric evaluation of the Italian Revised Exercise Addiction Inventory (EAI-R) among Italian speaking exercisers: confirmatory factor analysis
Background: The Exercise Addiction Inventory (EAI) is a valid and reliable instrument and has been used in numerous contexts and research studies. The EAI was recently revised (EAI-R), but the psychometric properties of the EAI-R have yet to be examined in an Italian context. Therefore, the present study aimed to validate the EAI-R among Italian-speaking exercisers.
Methods: The sample comprised 200 Italian-speaking exercisers (62% females, 38% male; mean age = 35 years, SD±11.42), who completed a survey including the EAI-R, Depression Anxiety and Stress Scale-21 (DASS-21), Rosenberg's Self-Esteem Scale (RSES), and Exercise Dependence Scale-Revised (EDS-R).
Results: Confirmatory factor analysis (CFA) showed the EAI-R had good psychometric characteristics (Cronbach's α = 0.90) and confirmed the scale's unidimensional properties. Scores on the EAI-R were positively correlated with EDS-R scores, the number of weekly hours of exercise, and DASS-21 scores. Conversely, EAI-R scores were negatively correlated with the RSES scores and age.
Conclusion: The EAI-R is a psychometrically reliable and valid measure for assessing the risk of exercise addiction among Italian adults. The study expands the literature on exercise addiction and demonstrates important associational factors in the Italian context

Italian validation of the Instagram Addiction Scale and association with psychological distress, social media addiction, smartphone addiction, and internet use disorder
The problematic use of Instagram in the form of addiction has gained increasing credibility and attention in recent years, leading to the development of several psychometric instruments to assess the behavior. One recently developed tool is the 15-item Instagram Addiction Scale (IAS-15). The IAS-15 comprises two subscales assessing social effect and compulsion. In the present study, the IAS-15 was translated into Italian, and its reliability and validity were tested among 398 Italians (101 males, 297 females) aged 18 to 78 years (mean age M=37 years; SD=11). Confirmatory factor analysis supported the original two-factor solution. Furthermore, the scale showed good internal consistency. Additionally, Instagram addiction was positively associated with social phobia, depression, anxiety, stress, social media addiction, smartphone addiction, and internet use disorder while being negatively associated with age, perceived quality of life, and quality of sleep. Based on the findings, the IAS-15 is a valid and reliable psychometric instrument to assess Instagram addiction among Italian adults
