Childhood maltreatment (CM) is associated with negative mental health outcomes. Many studies conceptualize resilience as experiencing CM without developing psychopathology (primary resilience). However, some people may develop subsequent but recover and demonstrate higher global functioning (secondary This study investigated the role of salience emotion network (SEN) (including amygdala, subgenual anterior cingulate cortex, insula) cognitive control (CCN) dorsolateral prefrontal inferior...

Abstract Background Adolescent-onset depression often results in a chronic and recurrent course, is associated with worse outcomes relative to adult-onset depression. Targeting habitual depressive rumination, specific known risk factor for relapse, may improve clinical adolescents who have experienced episode. Randomized controlled trials (RCTs) thus far demonstrated that rumination-focused cognitive behavioral therapy (RFCBT) reduces symptoms relapse rates patients residual young adults...

Abstract The dynamics of parent‐infant physiology are essential for understanding how biological substrates emotion regulation organized during infancy. Although physiological processes dyadic in nature, research is limited one person's responses predict one's own and as well the other subsequent moment. In this study, we examined mother‐infant respiratory sinus arrhythmia (RSA) Still‐Face Paradigm (SFP) among 106 mothers ( M age = 29.54) their 7‐month‐old infants (55 males). Given mothers'...

Abstract This study tested whether newborn attention and arousal provide a foundation for the dynamics of respiratory sinus arrhythmia (RSA) in mother–infant dyads. Participants were 106 mothers ( M age = 29.54) their 7‐month‐old infants (55 males 58 White non‐Hispanic). Newborn measured shortly after birth using NICU Network Neurobehavioral Scale. Higher predicted slower return infant RSA to baseline. Additionally, greater mothers’ baseline following still‐face paradigm, this effect only...

Strategies to link impulsivity and self-injurious behaviors (SIBs) show highly variable results, may differ depending on the measure used. To better understand this lack of consistency, we investigated correlations between self-report behavioral impulsivity, inhibitory control, SIBs, rumination. We included participants aged 13-17 years with either current or remitted psychopathology who have (n = 31) do not 14) a history SIBs. Participants completed measures Rumination Responsiveness Scale...

Ethical and consensual digital phenotyping through smartphone activity (i. e., passive behavior monitoring) permits measurement of temporal risk trajectories unlike ever before. This data collection modality may be particularly well-suited for capturing emotion dysregulation, a transdiagnostic factor psychopathology, across lifespan transitions. Adolescence, emerging adulthood, perinatal transitions are sensitive developmental periods, often marked by increased distress. These participant...

Abstract Introduction Rumination, or repetitive and habitual negative thinking, is associated with psychopathology related behaviors in adolescents, including non‐suicidal self‐injury (NSSI). Despite the link between self‐reported rumination NSSI, there limited understanding of how represented at neurobiological level among youth NSSI. Method We collected neuroimaging data from 39 adolescents current past NSSI remitted major depression. Participants completed a induction fMRI task,...

Rumination is a transdiagnostic problem that common in major depressive disorder (MDD). Focused Cognitive Behavioral Therapy (RF-CBT) explicitly targets the ruminative habit. This study examined changes brain activation during rumination induction task adolescents with remitted MDD following RF-CBT. We also evaluated reliability of among who received treatment as usual (TAU).Fifty-five ages 14-17 completed self-relevant fMRI and were then randomized to either RF-CBT (n = 30) or TAU 25)....
