Latent Negative Self-schema and High Emotionality in Well Adolescents at Risk for Psychopathology / Raphael KELVIN in Journal of Child Psychology and Psychiatry, 40-6 (September 1999)

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 40-6 (September 1999) . - p.959-968 Titre : Latent Negative Self-schema and High Emotionality in Well Adolescents at Risk for Psychopathology Type de document : texte imprimé Auteurs : Raphael KELVIN, Auteur ; Ian M. GOODYER, Auteur ; John D. TEASDALE, Auteur ; Don BRECHIN, Auteur Année de publication : 1999 Article en page(s) : p.959-968 Langues : Anglais (eng) Mots-clés : Adolescence  self-schema  temperament  depression Index. décimale : PER Périodiques Résumé : Teasdale's (1988) differential activation hypothesis proposes that a tendency for negative mood to activate latent negative self-schemas characterises people at risk for depression. The current study tested predictions from this hypothesis in a community sample of 102 adolescents who were free from history of psychiatric illness, and who were subdivided according to level of emotionality, a temperamental style as assessed by parental questionnaire.Amusical mood induction task was used to induce temporary mild dysphoria, and the effect of mood induction on self-schemas was assessed. There was no difference between high and low emotionality groups in the liability to sad mood induction. However, adolescents with high emotionality endorsed significantly more negative self-descriptors after dysphoric, but not after neutral, mood induction. This was not accounted for by level of self-reported depressive symptoms over the previous week. This suggests that a “dysphoric mood induction challenge” may provide important information about vulnerability to depression that is not identified by routine self-report of mood or cognitions.

Toward precision therapeutics: general and specific factors differentiate symptom change in depressed adolescents / Madison AITKEN in Journal of Child Psychology and Psychiatry, 61-9 (September 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-9 (September 2020) . - p.998-1008 Titre : Toward precision therapeutics: general and specific factors differentiate symptom change in depressed adolescents Type de document : texte imprimé Auteurs : Madison AITKEN, Auteur ; John D. HALTIGAN, Auteur ; Peter SZATMARI, Auteur ; Bernadka DUBICKA, Auteur ; Peter FONAGY, Auteur ; Raphael KELVIN, Auteur ; Nick MIDGLEY, Auteur ; Shirley REYNOLDS, Auteur ; Paul O. WILKINSON, Auteur ; Ian M. GOODYER, Auteur Année de publication : 2020 Article en page(s) : p.998-1008 Langues : Anglais (eng) Mots-clés : Bifactor models  adolescent  depression  psychopathology  psychotherapy Index. décimale : PER Périodiques Résumé : BACKGROUND: The longitudinal course of multiple symptom domains in adolescents treated for major depression is not known. Revealing the temporal course of general and specific psychopathology factors, including potential differences between psychotherapies, may aid therapeutic decision-making. METHODS: Participants were adolescents with major depressive disorder (aged 11-17; 75% female; N = 465) who were part of the IMPACT trial, a randomized controlled trial comparing cognitive behavioral therapy, short-term psychoanalytic psychotherapy, and brief psychosocial intervention. Self-reported symptoms at baseline and 6, 12, 36, 52, and 86 weeks postrandomization were analyzed with bifactor modeling. RESULTS: General psychopathology factor scores decreased across treatment and one-year follow-up. Specific melancholic features and depressive cognitions factors decreased from baseline to 6 weeks. Conduct problems decreased across treatment and follow-up. Anxiety increased by 6 weeks and then reverted to baseline levels. Obsessions-compulsions did not change. Changes in general and specific factors were not significantly different between the three psychotherapies during treatment. During follow-up, however, conduct problems decreased more in brief psychosocial intervention versus cognitive behavioral therapy (1.02, 95% Bayes credible interval 0.25, 1.96), but not versus short-term psychoanalytic psychotherapy. CONCLUSIONS: The clinical response signature in this trial is best revealed by rapid reductions in depression symptoms and general psychopathology. Protracted improvements in general psychopathology and conduct problems subsequently occur. Psychosocial treatments for adolescent depression have comparable effects on general and specific psychopathology, although a psychoeducational, goal-focused approach may be indicated for youth with comorbid conduct problems.

Trajectories of depression symptom change during and following treatment in adolescents with unipolar major depression / Sian Emma DAVIES in Journal of Child Psychology and Psychiatry, 61-5 (May 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-5 (May 2020) . - p.565-574 Titre : Trajectories of depression symptom change during and following treatment in adolescents with unipolar major depression Type de document : texte imprimé Auteurs : Sian Emma DAVIES, Auteur ; Sharon NEUFELD, Auteur ; Eleonore VAN SPRANG, Auteur ; Lizanne SCHWEREN, Auteur ; Rogier KEIVIT, Auteur ; Peter FONAGY, Auteur ; Bernadka DUBICKA, Auteur ; Raphael KELVIN, Auteur ; Nick MIDGLEY, Auteur ; Shirley REYNOLDS, Auteur ; Mary TARGET, Auteur ; Paul WILKINSON, Auteur ; Anne-Laura VAN HARMELEN, Auteur ; Ian M. GOODYER, Auteur Article en page(s) : p.565-574 Langues : Anglais (eng) Mots-clés : Depression  longitudinal studies  outcome  therapy Index. décimale : PER Périodiques Résumé : OBJECTIVE: To classify a cohort of depressed adolescents recruited to the UK IMPACT trial, according to trajectories of symptom change. We examined for predictors and compared the data-driven categories of patients with a priori operational definitions of treatment response. METHOD: Secondary data analysis using growth mixture modelling (GMM). Missing data were imputed. Trajectories of self-reported depressive symptoms were plotted using scores taken at six nominal time points over 86 weeks from randomisation in all 465 patients. RESULTS: A piecewise GMM categorised patients into two classes with initially similar and subsequently distinct trajectories. Both groups had a significant decline in depressive symptoms over the first 18 weeks. Eighty-four per cent (84.1%, n = 391) of patients were classed as 'continued-improvers' with symptoms reducing over the duration of the study. A further class of 15.9% (n = 74) of patients were termed 'halted-improvers' with higher baseline depression scores, faster early recovery but no further improvement after 18 weeks. Presence of baseline comorbidity somewhat increased membership to the halted-improvers class (OR = 1.40, CI: 1.00-1.96). By end of study, compared with classes, a clinical remission cut-off score (/=50%) indexing treatment response misclassified 15% and 31% of cases, respectively. CONCLUSIONS: A fast reduction in depressive symptoms in the first few weeks of treatment may not indicate a good prognosis. Halted improvement is only seen after 18 weeks of treatment. Longitudinal modelling may improve the precision of revealing differential responses to treatment. Improvement in depressive symptoms may be somewhat better in the year after treatment than previously considered.
