Annual Research Review: Puberty and the development of anhedonia - considering childhood adversity and inflammation / Tina GUPTA in Journal of Child Psychology and Psychiatry, 65-4 (April 2024)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 65-4 (April 2024) . - p.459-480 Titre : Annual Research Review: Puberty and the development of anhedonia - considering childhood adversity and inflammation Type de document : texte imprimé Auteurs : Tina GUPTA, Auteur ; Kristen L. ECKSTRAND, Auteur ; Erika E. FORBES, Auteur Article en page(s) : p.459-480 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Anhedonia, or diminished pleasure and motivation, is a symptom of severe mental illness (e.g., depressive disorder, bipolar disorder, schizophrenia) that emerges during adolescence. Anhedonia is a pernicious symptom that is related to social impairments, treatment resistance, and suicide. As the mechanisms of anhedonia are postulated to include the frontostriatal circuitry and the dopamine neuromodulatory system, the development and plasticity of these systems during the vulnerable period of adolescence, as well as their sensitivity to pubertal hormones, suggest that pubertal maturation could play a role in the development of anhedonia. This review takes a developmental perspective, considering the possibility that anhedonia emerges in the context of pubertal maturation and adolescent development, with childhood adversity and chronic inflammation influencing neural reward systems to accelerate anhedonia's progression. Here, we review the relevant extant literature on the components of this model and suggest directions for future research.

Trajectories of distressing psychotic-like experience in youth: the interplay of recent negative life events and screen time / Tina GUPTA in Development and Psychopathology, 38-4 (October 2026)  

Public ISBD [article]  inDevelopment and Psychopathology > 38-4 (October 2026) . - p.1797-1807 Titre : Trajectories of distressing psychotic-like experience in youth: the interplay of recent negative life events and screen time Type de document : texte imprimé Auteurs : Tina GUPTA, Auteur ; Megan DEAM, Auteur ; Emma HEADLEY, Auteur ; Tien Hong Stanley SEAH, Auteur ; Jennifer SILK, Auteur ; Julianne Marie GRIFFITH, Auteur ; Teresa VARGAS, Auteur ; Sabrina MESSINEO, Auteur ; Leslie HORTON, Auteur Article en page(s) : p.1797-1807 Langues : Anglais (eng) Mots-clés : adolescence  negative life events  psychotic-like experiences  screen time  trajectories Index. décimale : PER Périodiques Résumé : Adolescence is marked by increased risk for psychopathology, alongside behavioral changes such as greater screen time. Adolescents who experience distressing psychotic-like experiences (PLEs) are particularly vulnerable to the onset of psychopathology and often report exposure to negative life events. This study examined how screen time and recent negative life events contribute to trajectories of PLE distress using the Adolescent Brain Cognitive Development (ABCD) Study®. Latent Growth Mixture Models identified PLE distress trajectories over five timepoints. Linear mixed-effects models assessed how screen time, recent negative life events, and their interactions predicted these trajectories. Sensitivity analyses were conducted examining the influence of cumulative stress. Three PLE distress trajectories emerged: increasing, decreasing, no distress. The increasing and decreasing PLE distress trajectories reported similar amounts of daily screen time. However, youth in the increasing PLE distress trajectory reported more recent negative life events, and associations between more weekend texting and social media use at ages 11–12 and PLE distress levels at ages 13–14 were strongest for people who were exposed to more recent negative life events (but not cumulative stress). These findings suggest that more proximal adverse life experiences may have an impact on screen time and PLE distress levels.
