Moreover, we tested whether Internet use disorder is characterized by a specific network of symptoms. One-hundred-and-four young adults (78 women) were assessed in laboratory using self-report measures of Internet addiction, alcohol use disorder, cannabis abuse, depression, anxiety, and stress symptoms, impulsiveness, and obsessive-compulsive symptoms. Only hoarding, obsessing, and depression symptoms were positively linked to Internet use disorder severity, with hoarding having greater power and accuracy than other obsessive-compulsive and affective symptoms. Only individuals with mild-moderate Internet use disorder were characterized by a network of strong and positive associations of affective and obsessive-compulsive symptoms. These findings may encourage future longitudinal studies aimed at identifying potential clinical criteria for the diagnosis of Internet use disorder and treatment targets.<\/jats:p>","DOI":"10.3389\/fpsyg.2021.700518","type":"journal-article","created":{"date-parts":[[2021,8,12]],"date-time":"2021-08-12T02:44:09Z","timestamp":1628736249000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":14,"title":["The Relationship Between Affective and Obsessive-Compulsive Symptoms in Internet Use Disorder"],"prefix":"10.3389","volume":"12","author":[{"given":"Tania","family":"Moretta","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giulia","family":"Buodo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,8,12]]},"reference":[{"key":"B1","volume-title":"Guida utile all'identificazione e alla diagnosi dei problemi alcol-relati","author":"Addolorato","year":"1999"},{"key":"B2","volume-title":"Diagnostic and Statistical Manual of Mental Disorders.
