Online activities are a fundamental part of daily life in this digital era and Internet self-efficacy (ISE) became a central construct for the psychologists of virtual environments. The Internet Self-Efficacy Scale developed by Kim and Glassman (2013) is a recent, valid, and reliable 17-item test to assess the ISE. The aim of this research, composed by two studies, was to translate and validate the Italian version of the ISS. In study 1, we evaluated the factorial validity and internal consistency of the Italian version of the ISS on 3724 individuals. In study 2, we tested the ISS external validity relying on the Bergen Social Media Addiction Scale (BSMAS) and the Internet Addiction Scale (IAS) based on the answers of 244 participants. The findings supported the reliability and validity of the translated ISS and its use for assessing ISE on the Italian population. Implications for researchers and interventions are also discussed.

Objectives: How individuals perceive the risk of COVID-19 influences their mental health and protective behaviors. Therefore, the development of an instrument to capture COVID-19-related worries and fears is relevant. This study aims to develop and validate the CoV-WoFe to measure COVID-19-related worries and fears.Methods: An online questionnaire was completed by 593 participants during Christmas 2020 and by 328 participants during Summer 2021, from which 88 participants formed a longitudinal sample.Results: Analyses confirmed a robust adjustment for consistency over time and a gender-invariant bifactorial structure. Factor 1 represented worry about the health consequences of COVID-19 and Factor 2 represented the perceived physiological symptoms associated with fear of COVID-19. Construct validity was evidenced by: the expected relations between the CoV-WoFe and other theoretically related constructs; the serial mediating role of both dimensions in the relationship that security values establish with protective behaviors against COVID-19 and with anxiety; and the expected gender differences in the Cov-WoFe.Conclusion: The CoV-WoFe represents a short, valid, reliable, gender-invariant tool that is easy to apply in both the health professional and research context to assessCOVID-19-related worries and fears, which are variables of relevance for spread of the virus and for mental health.
