To examine the added value of a 9-week mindful yoga intervention (MYI) as add-on to treatment as usual (TAU) in reducing depression for young women (18-34 years) with major depressive disorder (MDD). Randomized controlled trial (RCT; n = 171) comparing TAU + MYI with TAU-only. Assessments were at baseline, postintervention, and at 6- and 12-month follow-up. Primary outcome measures were...

OBJECTIVES: Despite the gains made by current first-line interventions for major depressive disorder (MDD), modest rates of treatment response and high relapse indicate the need to augment existing interventions. Following theory and initial research indicating the promise of mindful yoga interventions (MYIs), this study examines mindful yoga as a treatment of MDD. METHODS/DESIGN: This...

Course of auditory vocal hallucinations in childhood: 11‐year follow‐up study

Acta Psychiatrica Scandinavica March 24, 2016 Agna A. Bartels‐Velthuis, Johanna T. W. Wigman, Jack A. Jenner et al. 68 citations

OBJECTIVE: Childhood auditory vocal hallucinations (AVH) are mostly transient but may predict clinical outcomes. Little is known about their course over time and associations with risk factors, and how this may inform early intervention. Our objective was to assess the 11-year course of AVH, associated psychopathology and risk factors. METHOD: A 5-year (T1) and 11-year (T2) follow-up of a...

The training consisted of nine weekly 2.5-h sessions. Thirty-three patients, who had followed a mindfulness-based stress...

From phenomenology to neurophysiological understanding of hallucinations in children and adolescents.

Schizophrenia Bulletin July 2014 Renaud Jardri, Agna A. Bartels‐Velthuis, Martin Debbané et al.

Typically reported as vivid, multisensory experiences which may spontaneously resolve, hallucinations are present at high rates during childhood. The risk of associated psychopathology is a major cause of concern. On the one hand, the risk of developing further delusional ideation has been shown to be reduced by better theory of mind skills. On the other hand, ideas of reference, passivity...
