This study assessed the potential short-term effects of COVID-19 stay-at-home restrictions on ratings of ASD and comorbid symptoms severity and adaptive functioning of 69 youth, ages 8-16 years with ASD without intellectual disability. Parent/caregiver ratings were being collected in fall and spring over approximately two years when the…

Introduction: Children and young adults with Down syndrome can demonstrate increased behavior problems compared to their typically developing peers through childhood and adolescence. Though current tools measure behavior problems in persons with intellectual disabilities, they do not capture all the behavioral problems that can occur in…

Prevalence of self-injurious behavior (SIB) is as high as 50% among children with autism spectrum disorder (ASD). Identification of risk factors for the development of SIB is critical to early intervention and prevention. However, there is little empirical research utilizing a prospective design to identify early risk factors for SIB. The purpose…

Neurofibromatosis Type 1 (NF1) is a common autosomal dominant single-gene disorder, in which the co-occurrence of autism spectrum disorder (ASD) has attracted considerable research interest recently with prevalence estimates of 21-40%. However, detailed characterization of the ASD behavioral phenotype in NF1 is still lacking. This study…

Poor reciprocity is a defining feature of an autism spectrum disorder (ASD). In the current study, we examined the reliability and validity of the Interactive Drawing Test (IDT), a new instrument to assess reciprocal behavior. The IDT was administered to children and adolescents with ASD (n = 131) and to a typically developing group (n = 62). The…

Manual dexterity is known to gradually progress with developmental age. In this study, we evaluate the performance of unimanual and bimanual actions under perturbed and unperturbed conditions in children between 4 and 10 years of age. Behavior was assessed by means of trajectory measurements and degree of bimanual coupling. The results showed that…

This investigation used an ABAB withdrawal design to determine the effect of self-monitoring using the MotivAider® (MotivAider, 2000) on percentage of intervals of on-task behavior by an 11-year old male with a moderate intellectual disability who attended a rural middle school. The MotivAider® is a small device, the size of a pager, which can be…

Provides recommendations for improving the accuracy of diagnosing Attention Deficit/Hyperactivity Disorder using rating scales of procedures. Outlines strategies for managing the error intrinsic to the use of diagnostic measures, specifically behavior rating scales. Recommends a multiple stage procedure involving one or more levels of screening…

Research on child influence upon parent behavior motivated the development of a Parent Report of Child Behavior Toward the Parent Inventory. Internal consistency reliabilities of 31 five-item scales ranged from .69 to .95 with a median of .88. Varimax rotation of three principal component factors yielded dimensions of Control, Acceptance versus…

A study attempted to replicate a previous study that presented reliability data from recordings of behavior state using a 13-category coding system. Replication was unsuccessful. Obtained mean percentage agreement on occurrence for individual behavior state and participants (n=34) ranged across observer pairs from 0 to 58 percent. (Contains 13…

Examines relations between Matthews Youth Test for Health ratings on hyperactive boys and diverse measures obtained from five sources: direct behavior observations; staff evaluations, nonparticipant observer ratings, peer nominations, and self-reports. (HOD)

A Children's Depression Rating Scale (CDRS) was devised and tested on 30 inpatient children (6 to 12 years old) in a medical hospital. A high correlation was found between global ratings by two psychiatrists of severity of depression and scores on the CDRS. Journal availability: American Academy of Pediatrics, P.O. Box 1034, Evanston, IL 60204.…

Two observational systems were employed to measure the behavior patterns of two elementary-age autistic children and their classroom peers during a free-play period. The results obtained were discussed in terms of their significance for the clinical treatment of autistic behavior, and the evaluation of such treatment. (Author)

The classroom behavior of 11 segregated and 11 integrated educable mentally retarded (EMR) children, 8 to 13 years of age, was compared on a 12-category observation schedule when all EMR children were in special classes, four months after some children had been reintegrated, and at the conclusion of an academic year. The results indicated that…
