To examine these concerns, the aim of the present study was to assess longitudinal changes in addictive and problematic behaviors (i.e., problematic social media use, Internet gaming disorder, gambling disorder, problematic pornography use, and compulsive sexual behavior disorder) over time during the COVID-19 pandemic.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Three waves of data collection took place in different stages of the COVID-19 outbreak in Hungary in a general population, from the first wave of lockdowns to the second and third waves of restrictions (May, 2020; N\n                      <jats:sub>\n                        <jats:italic>T<\/jats:italic>\n                        1\n                      <\/jats:sub>\n                      = 1747; June\u2013August, 2020; N\n                      <jats:sub>\n                        <jats:italic>T<\/jats:italic>\n                        2\n                      <\/jats:sub>\n                      = 656; January, 2021; N\n                      <jats:sub>\n                        <jats:italic>T<\/jats:italic>\n                        3\n                      <\/jats:sub>\n                      = 411).

However, the rate of this change was negligible. Overall, there were no noteworthy changes over time regarding any of the examined addictive and problematic behaviors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Contrary to initial concerns, no substantial changes over time were observed regarding the examined addictive behaviors during the COVID-19 pandemic and related lockdowns.
