We provide an overview of the CLPsych 2022 Shared Task, which focusses on the automatic identification of Moments of Change in longitudinal posts by individuals on social media and its connection with information regarding mental health . This year\u27s task introduced the notion of longitudinal modelling of the text generated by an individual online over time, along with appropriate temporally sensitive evaluation metrics. The Shared Task consisted of two subtasks: (a) the main task of capturing changes in an individual\u27s mood (drastic changes-`Switches\u27- and gradual changes -`Escalations\u27- on the basis of textual content shared online; and subsequently (b) the sub-task of identifying the suicide risk level of an individual -- a continuation of the CLPsych 2019 Shared Task-- where participants were encouraged to explore how the identification of changes in mood in task (a) can help with assessing suicidality risk in task (b)
