Knowledge, Attitudes, and Behaviors Towards Cyberchondria: A Cross-Sectional Study Among Italian Adolescents

Background/Objectives: Cyberchondria is the compulsive and repetitive search for health-related information online. Adolescents may be vulnerable to cyberchondria due to extensive Internet use and developing health literacy skills; however, evidence from Italy remains limited. The aim of this study is to examine knowledge, attitudes, and behaviors related to cyberchondria among Italian adolescents aged 10-19 years and identify the associated factors. Methods: This cross-sectional investigation was conducted from January to March 2025 among adolescents in Naples, southern Italy. Data collection relied on a self-administered structured questionnaire, including the Cyberchondria Severity Scale-12 (CSS-12). Two multivariate logistic regression models identified independent predictors of online health information-seeking and high cyberchondria (CSS-12 ≥ 32 points). Results: Among 793 participants (mean age 15.8 ± 2.2 years; 50% female), 59.7% used the Internet to seek health information, and this behavior was independently associated with older age, female gender, lower self-perceived health, chronic conditions, and increasing CSS-12 values. The mean CSS-12 score reached 31.2 ± 8.3, and 53.4% of participants scored ≥ 32 points. Higher cyberchondria was associated with believing that the Internet is useful for health decision-making, needing more information about cyberchondria, needing more information about a health topic, perceiving the Internet as important for health resources, having a father with a high school diploma or less, and having parents without underlying chronic medical conditions. Conclusions: Italian adolescents commonly use the Internet to seek health information, and they present non-negligible cyberchondria levels. This study's findings emphasize the need for targeted educational interventions promoting safe and critical online health information-seeking behaviors.
