(27, 28) However, it is not possible to establish if these frequencies are characteristic of CPBD or whether they would be the same as those of a control group from the community.
The objective of this study is to compare the psychopathological characteristics of a group of CPBD and a group of CCP using validated diagnostic instruments.
Those who were included formed the CPBD and CCP populations if they met the following eligibility criteria: aged 6-30 years with no health problems preventing them from participating in a clinical interview, moderate or severe mental retardation, or classic autism according to criteria of the Fourth Edition of the Diagnostic and Statistical Manual of Mental Disorders-Revised Text (DSM-IV-RT).
To calculate the sample size, a prevalence of general psychiatric disorders among CPBD of 16%, (32) a power of 80% and a type I error of 5% were taken as a reference.
The screening of the sample of children was initially carried out among the CPBD, followed by the CCP, until a sufficient number of comparable children was found according to the variables of gender, age group and origin.
CPBD under the age of 18 were subjected to the Schedule for Affective Disorders and Schizophrenia for School Aged Children Lifetime version (K-SADS-PL), (34, 35) with the aim of establishing the presence of psychiatric diagnoses according to the DSM-IV-RT criteria.
To describe the differences in psychiatric disorders between CPBD and CCP, three age groups were considered.
When empty boxes were found in the comparisons between CPBD and CCP due to the absence of individuals with a certain characteristic, a Yates's correction was performed.
