We aimed to investigate adolescents' emotional/beha-vioral problems and internet/smartphone usage features during this pandemic and to compare the findings with the pre-pandemic features.Method: The sample consisted of 57 adolescents (27 males, 30 females). Data were collected at two-time intervals: before the COVID-19 pandemic [T1] and during the COVID-19 pandemic [T2]. All participants fulfilled the Strengths and Difficulties Questionnaire (SDQ), The Young's Internet Addiction Test (IAT), Smartphone Addiction Scale-Short Version (SAS-SV).Results: The results indicated that both internet and smartphone use duration significantly increased at T2(P < 0.001). With regards to SDQ, emotional symptoms, hyperactivity problems, prosocial behaviors, and total difficulties subscales were significantly worse at T2 than T1 (P < 0.05). Additionally, significant correlations were found between IAT and SAS scores and SDQ behavioral problems, hyperactivity-inattention subscores, and total difficulties scores (P<0.001). Finally, according to regression analysis hyperactivity-inattention problems increased the risk of problematic internet use (P < 0.05).Discussion: We objectively observed internet and smartphone use increase and relations with emotional and behavioral problems among adolescents during the outbreak of Covid-19. Therefore, these results should be carefully kept in mind while developing health policies for the long-term effects of the pandemic, whose duration is not yet known.eninfo:eu-repo/semantics/openAccessAddictionPrevalenceStudentsSymptomsChildrenSamplePandemicInternet addictionSmartphone addictionEmotional problemsBehavioral problemsPsychiatryArticle00109437680000618619226310.5505/kpd.2023.46144
