Emotion Control Predicts Internalizing and Externalizing Behavior Problems in Boys With and Without an Autism Spectrum Disorder

Children and adolescents with Autism Spectrum Disorder (ASD) often show comorbid emotional and behavior problems. The aim of this longitudinal study is to examine the relation between emotion control (i.e., negative emotionality, emotion awareness, and worry/rumination) and the development of internalizing and externalizing problems. Boys with and without ASD (N = 157; age 9–15) were followed over a period of 1.5 years (3 waves). We found that baseline levels of worry/rumination was a specific predictor of later externalizing problems for boys with ASD. Furthermore, the developmental trajectory of worry/rumination predicted the development of internalizing and externalizing problems in both groups. Our findings suggest that worry/rumination may constitute a transdiagnostic factor underlying both internalizing and externalizing problems in boys with and without ASD

Longitudinal Associations Between Bullying and Emotions in Deaf and Hard of Hearing Adolescents

In hearing adolescents, emotions play important roles in the development of bullying and victimization. Yet, it is unclear whether this also applies to adolescents who are deaf or hard of hearing (DHH). The present study examines the longitudinal associations of anger, fear, guilt, and shame with bullying/victimization in DHH adolescents. Overall, 80 DHH and 227 hearing adolescents (Mage = 11.7; 103 males) completed self-reports on two occasions with a 9-month interval. Outcomes show that DHH adolescents reported fewer bullying behaviors, but more victimization compared to hearing adolescents. Longitudinal relations between emotions and bullying/victimization did not differ between DHH and hearing adolescents. More anger and less guilt predicted increased bullying, and more bullying predicted increased anger and decreased guilt. Higher levels of anger, fear, and shame predicted increased victimization, and more victimization predicted increased anger, fear, and shame. These findings emphasize that emotions are involved in both the emergence and maintenance of bullying and victimization. These outcomes have clinical implications for the prevention of bullying

Resting Heart Rate Variability Predicts Safety Learning and Fear Extinction in an Interoceptive Fear Conditioning Paradigm

This study aimed to investigate whether interindividual differences in autonomic inhibitory control predict safety learning and fear extinction in an interoceptive fear conditioning paradigm. Data from a previously reported study (N = 40) were extended (N = 17) and re-analyzed to test whether healthy participants' resting heart rate variability (HRV) - a proxy of cardiac vagal tone - predicts learning performance. The conditioned stimulus (CS) was a slight sensation of breathlessness induced by a flow resistor, the unconditioned stimulus (US) was an aversive short-lasting suffocation experience induced by a complete occlusion of the breathing circuitry. During acquisition, the paired group received 6 paired CS-US presentations; the control group received 6 explicitly unpaired CS-US presentations. In the extinction phase, both groups were exposed to 6 CS-only presentations. Measures included startle blink EMG, skin conductance responses (SCR) and US-expectancy ratings. Resting HRV significantly predicted the startle blink EMG learning curves both during acquisition and extinction. In the unpaired group, higher levels of HRV at rest predicted safety learning to the CS during acquisition. In the paired group, higher levels of HRV were associated with better extinction. Our findings suggest that the strength or integrity of prefrontal inhibitory mechanisms involved in safety- and extinction learning can be indexed by HRV at rest
