Subjective Triggering Conditions of Affective Episodes in Adolescents and Young Adults from the General Population

Abstract

Introduction Affective episodes often emerge in adolescence and young adulthood. Identification of factors subjectively associated with their onset may improve aetiological models and targeted intervention. Objectives To examine precipitating conditions of (hypo-)manic and depressive episodes in adolescents and young adults from the general population. Methods A random sample of 14-21 year-olds was drawn from the population registry of Dresden, Germany, and N=1180 were assessed in 2015/2016 (response rate: 21.7%). Lifetime depressive and (hypo-)manic symptoms as well as full-threshold depressive and (hypo-)manic episodes (DSM-5) were identified using standardized interview. Participants reporting depressive or (hypo-)manic symptoms were asked whether and which events or conditions they associate with episode onset. Besides responses on a list providing potential triggering conditions a free answer was possible. Qualitative content analysis preceded quantitative logistic regression analyses (significance level p<.05). Considered categories were: negative life events (further divided for depression into loss/danger events, burdensome life conditions, and interpersonal factors), events requiring adaptation, positive life events, internal factors, and other factors. Results The vast majority of participants reporting depressive (n=682) respectively (hypo-)manic (n=200) symptoms also reported a precipitating condition (94.7%, 83.1%). There was no significant association between any triggering condition and the occurrence of a full-threshold depressive (n=206) or (hypo-)manic (n=25) episode. However, the number of reported categories of precipitating conditions was associated with full-threshold depressive and (hypo-)manic episodes. Among those with depressive or (hypo-)manic symptoms and at least one reported precipitating condition, multiple regression models including all condition categories showed that in particular internal factors, interpersonal problems and other factors were associated with the occurrence of a full-threshold depressive episode (n=199) and positive life events as well as internal factors were associated with the occurrence of a full-threshold (hypo-)manic episode (n=21). Conclusions Adolescents and young adults from the general population usually associate the onset of phases with affective symptoms with precipitating conditions but these do not necessarily signal the emergence of a diagnostically relevant episode. Nevertheless, a greater number of and the presence of particular precipitating conditions may indicate the emergence of full-blown depressive or (hypo-)manic episodes. Thus, asking for subjective triggers appears relevant and may guide early identification and intervention. Disclosure of Interest None Declared
