Background: Abnormal sensory reactivity is considered one of the diagnostic criteria for autism spectrum disorders (ASD) and has been associated with autism severity, poorer functional outcomes, and behavioral difficulties across the lifespan. Its early characterization could provide valuable insights into the processes favoring the instantiation of maladaptive behaviors. Objectives: The present study has two aims: (1) to describe the sensory profile of preschool children with ASD compared with an age-matched population of children with a diagnosis of language disorder (DLD) and typically developing (TD) control peers; (2) to explore within each group whether the sensory alterations play a predictive role in the instantiation of emotional and behavioral issues. Methods: The parents of 42 ASD, 18 DLD, and 56 TD filled out the Sensory Processing Measure—Preschool (SPM-P). To gather information on competencies, behaviors, and emotional problems of children, the Child Behavior Checklist 1½-5 (CBCL 1½-5) was also administered. Results: On the SPM-P, ASD and DLD samples generally had scores more compromised than control peers. The contrast between ASD and DLD was reflected in a higher (and highly significant) impairment on the social participation and hearing subscales, suggesting a greater sensitivity and a possible specificity of these scores for ASD. More importantly, linear regression analyses revealed a strong and predictive association for ASD children with SPM total scores explaining more than 50% of the variance of the CBCL 1½-5 total scores (p < 0.001). Conclusions: Our findings reinforce the need to detect the abnormal sensory profiles of ASD already at an early stage and during clinical evaluations. Due to the impact on the emotional and behavioral manifestations, such a procedure has significant clinical and social implications, potentially guiding the development of new interventions relying on multisensory strategies.

It is currently debated whether specific psychiatric disorders or Internalizing versus Externalizing psychopathological dimensions are associated to Internet Addiction Disorder (IAD). We explored this issue in youth with and without IAD referred to a third-level Department of Adolescent Psychiatry during a 12-month period. All the 101 consecutively referred adolescents were assessed using categorical (Schedule for Affective Disorders and Schizophrenia for School- Age Children-K-SADS) and dimensional (Child Behavior Checklist-CBCL) measures of psychopathology, and two measures for addictive behaviors, Internet Addiction Test (IAT) (used as screening for detecting IAD patients) and Use, Abuse, Dependence on the Internet (UADI) inventory. According to an IAT cutoff score of 50, 39 patients (38.6%) presented IAD. The IAD and the no IAD groups did not differ according to age and gender. Most of the IAD patients (92.3%) endorsed multiple addictions. The IAD group had higher scores in all the UADI dimensions, except for Impact of Life. All the IAD patients endorsed psychiatric diagnoses, but only Autism Spectrum Disorders were more represented in the IAD group. According to the CBCL, patients with IAD had more social problems and anxiety symptoms. However, clusters analysis with the t-scores of the CBCL scales of Internalizing and Externalizing domains showed no differences in IAT and UADI scores among clusters. The small sample size and a selection bias (referrals for severe symptomatology) limit the generalization of the findings. Comorbidity should be systematically assessed in IAD adolescents, with categorical and dimensional measures, as it may guide personalized treatments. [ABSTRACT FROM AUTHOR]

Although childhood-onset psychiatric disorders are often considered as distinct and separate from each other, they frequently co-occur, with partial overlapping symptomatology. Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) commonly co-occur with each other and with other mental disorders, particularly disruptive behavior disorders, oppositional defiant disorder/conduct disorder (ODD/CD). Whether these associated comorbidities represent a spectrum of distinct clinical phenotypes is matter of research. The aim of our study was to describe the clinical phenotypes of youths with ADHD with and without ASD and/or ODD/CD, based on neuropsychological and psychopathological variables. One-hundred fifty-one participants with ADHD were prospectively recruited and assigned to four clinical groups, and assessed by means of parent-reported questionnaires, the child behavior checklist and the behavior rating inventory of executive functions. The ADHD alone group presented a greater impairment in metacognitive executive functions, ADHD+ASD patients presented higher internalizing problems and deficits in Shifting tasks, and ADHD+ODD/CD subjects presented emotional-behavioral dysregulation. Moreover, ADHD+ASD+ODD/CD individuals exhibited greater internalizing and externalizing problems, and specific neuropsychological impairments in the domains of emotional regulation. Our study supports the need to implement the evaluation of the psychopathological and neuropsychological functioning profiles, and to characterize specific endophenotypes for a finely customized establishment of treatment strategies.
