Each assessment was conducted on two half-day or one full-day period depending on the child’s endurance. For preschool children (four to five years of age), assessments lasted an average of 4.5 h, while for school-aged children, they lasted approximately 6.5 h. In a small number of cases in which a previous assessment used several of the same tests within a one- to two-year period, these results were incorporated into the diagnostic process rather than repeating the particular measures.
After test administration and scoring of each child’s results, the checklist of deficits and assets was independently completed by the examiner and the supervising clinical psychologist to determine how well an individual child’s neurobehavioural profile resembled the ARND profile. Children were assigned to the ARND group if they achieved a minimum average of 60% for deficits and 50% for assets. These cut-offs were based on the authors’ initial impressions that many of the children with ARND do not present with the entire range of problems (or strengths), but rather a proportion of the features with a high degree of severity. For example, some children presented with 75% to 95% of the weaknesses, and others had profiles with weaknesses as low as 60%. These profiles were also deemed consistent with ARND given the severity of the problems. Although these cut-offs are arbitrary, there are no precedented methods to assist in this approach. buy ortho tri-cyclen online
