Increasing research underscores low positive emotion (PE) as a vital component of depression risk in adolescence. Theory also suggests that PE contributes to adaptive coping. However, it is unclear whether naturalistic experiences of emotions contribute to long-term depression risk, or whether daily PE levels equip adolescents to cope with later naturalistic stressors, reducing risk for depression. The current study examines whether PE (and negative emotion [NE]) assessed via ecological momentary assessment (EMA) (a) predict prospective increases in depression, and (b) moderate the association between later life stressors and depression. Longitudinal study of community-recruited adolescents, with EMA at baseline. Adolescents (n = 232) completed contextual threat life stress interviews, interview and self-report measures of depression at baseline and 1.5 year follow-up. At baseline, they completed a seven-day EMA of emotion. Preregistered analyses showed that daily NE, but not PE, predicted increased depression over time and moderated the association between interpersonal episodic stress and self-reported depression. Results did not support daily PE as a buffer against depressogenic effects of life stress, but point to daily NE as a marker of depression risk. [ABSTRACT FROM AUTHOR]

Objective: The study purpose was to examine the feasibility and acceptability of intensive ecological momentary assessment (EMA) among high-risk adolescents with suicidal thoughts and behaviors following discharge from acute psychiatric care. Method: Fifty-three adolescents, 12–18 years old, and their parents, were recruited following discharge from acute psychiatric care for suicide risk. The study included a baseline assessment (adolescent and parent), 28 days of EMA surveys (5x per day) and wrist actigraphy (adolescent), and an interview at the end of the 28-day monitoring period (adolescent). Adolescents' outpatient clinicians were also surveyed about the study. Results: Study feasibility was indicated by a reasonable enrollment rate, high adherence to wearing the actigraphy device, and good adherence to EMA surveys (highest in the first week with significant drop-off in subsequent weeks). Adolescents reported their overall experience in the study was positive, the questions were understandable, their responses to questions were generally accurate, and the surveys were minimally burdensome. The study procedures did not appear to be iatrogenic; suicide attempts and rehospitalizations were not study related and occurred at a rate comparable to other adolescents at the recruitment site. Adolescents' clinicians reported that the study was somewhat positive and minimally burdensome for them, and somewhat positive for their patients and families. Conclusions: This study demonstrated that intensive EMA designs are feasible and acceptable among high-risk suicidal youth following acute psychiatric care. Specific procedures are provided for keeping adolescents safe during intensive EMA studies, including detailed information about the risk and safety monitoring plan. [ABSTRACT FROM AUTHOR]

Emotion differentiation (ED; the ability to distinguish discrete internal emotion states) may reflect or benefit from knowledge of linguistic labels. The present study uses natural language processing to examine how emotion vocabulary (EV; diversity of unique emotion terms within active vocabulary) relates to ED and depression in an adolescent sample. We tested two competing preregistered (https://osf.io/4j75w/) models regarding the EV-ED link. In the lexical facilitation hypothesis , we posited that larger EV may inform ED, perhaps resulting in larger EVs being associated with greater ED. In the emotional concision hypothesis , we theorized that ED may reflect narrower emotional experiences that are more succinctly labelled, which could result in larger EV being associated with lower ED. A community sample of adolescents (N = 241, ages 14-17, predominantly White) completed interviews, self-report measures, and ecological momentary assessments as part of a larger study conducted between 2014 and 2016. EV was derived using speech samples from transcribed recordings of life stress interviews. In line with the emotion concision hypothesis, EV and ED were inversely related for negative emotions. Moreover, larger negative EV and lower negative ED were each uniquely associated with depression, casting further doubt on whether diverse negative EVs within spontaneous language are fundamentally adaptive for emotional functioning. Replication in more diverse samples is needed to extend generalizability. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
