Few studies have examined the phenomenology and correlates of PGD among children and adolescents. In part, this is due to the lack of a psychometrically sound questionnaire to assess PGD symptoms in these groups. Based on an adult measure of PGD, we developed two questionnaires of PGD symptoms for children and adolescents named the Inventory of Prolonged Grief for Children (IPG\u2010C) and Inventory of Prolonged Grief for Adolescents (IPG\u2010A), respectively. Psychometric properties of these measures were examined in three samples, including mostly parentally bereaved children (aged 8\u201312\u2009years, total sample <jats:italic>n<\/jats:italic>\u2009=\u2009169) and adolescents (aged 13\u201318\u2009years, total sample <jats:italic>n<\/jats:italic>\u2009=\u2009153). First, findings showed that items of the IPG\u2010C and IPG\u2010A represented one underlying dimension. Second, the internal consistency and temporal stability of both questionnaires were adequate. Third, findings supported the concurrent validity (e.g., significant correlations with measures of depression and post\u2010traumatic stress\u2010disorder [PTSD]), convergent and divergent validity (stronger correlations with similar questionnaires of \u2018traumatic grief\u2019 than with two dissimilar questionnaires of \u2018ongoing presence\u2019 and \u2018positive memories\u2019) and incremental validity (significant correlations with an index of functional impairment, even when controlling for concomitant depression and PTSD) of the IPG\u2010C and IPG\u2010A. This report provides further evidence of the clinical significance of PGD symptoms among children and adolescents and promising psychometric properties of questionnaires that can be used to assess these symptoms.
