The behavioural characteristics of 40 children with Down's syndrome were studied using the Achenbach Child Behavior Checklist which was completed by both the children's parents and teachers. Statistically significant differences were observed between study and control groups on externalizing and total scores on responses obtained from both parents and teachers, but not on internalizing scores. Further analysis of the data on a subgroup of 28 children between the ages of 6 and 11 years revealed… 
Maladaptive behaviour in children and adolescents with Down's syndrome.
TLDR
Older adolescents with DS may show decreased externalizing symptoms and subtle increases in withdrawal, and possible relationships are discussed between these shifts and increased risks of later-onset depression and Alzheimer's disease in adults with DS.
Temperament in children with Down syndrome and in prematurely born children.
TLDR
The children with Down syndrome had less attentional focusing and expressed less inhibitory control and less sadness than the normally developing children and the temperament structures in the Norwegian samples were very similar to those reported in earlier studies, conducted in China and the US.
Behavior problems of young girls with fragile X syndrome: factor scores on the Conners' Parent's Questionnaire.
TLDR
It is suggested that some behavior problems will be reported frequently in young girls with fra(X) and should not be difficult for clinicians to detect.
Behaviour phenotype for Down's syndrome
TLDR
This study confirms there to be a behaviour phenotype among adults with Down's syndrome and establishes a better understanding of the aetiologies of maladaptive behaviours among people with learning disabilities in general.
Spectrum of cognitive, behavioural and emotional problems in children and young adults with Down syndrome.
TLDR
IQ was significantly inversly related to the age of patients, and externalizing behaviours were significantly higher in the 5-10 years old group, whereas internalizing behaviours where more prevalent in adolescents and adults (10-30 years).
Reliability of parent report measures of behaviour in children with Down syndrome
TLDR
The study findings suggest that, among children with DS, some CBCL sub-scales generally performed in a psychometrically sound and theoretically appropriate manner in relation to other measures of behaviour.
Emotional and behavioral problems in children and adolescents with and without intellectual disability.
TLDR
Elevated scale scores reflected differences between children with and without ID over a broad range of items, and not solely on items more likely to be related to developmental delay, which deserve special attention in the mental health care of children with ID.
[A neuropsychological and behavioural profile of attention deficits in fragile X syndrome].
TLDR
Emerging evidence now supports the hypothesis that the fundamental deficit in fragile X is in controlling the flow of sequences of input and output and it is suggested that this control require inhibition.
Classroom behaviour, language competence, and the acceptance of children with Down syndrome by their mainstream peers
TLDR
Although behaviour problems were significantly worse in the children with Down syndrome, poor behaviour did not influence the other children to reject them and there was a different picture for typically developing children wherethere was a strong relationship between behaviour and peer acceptance.
Development, Problem Behavior, and Quality of Life in a Population Based Sample of Eight-Year-Old Children with Down Syndrome
TLDR
Eight-year-old children with DS have an average developmental delay of four years, more often have emotional and behavioral problems, and have a less favorable Health-Related Quality of Life compared with children from the general population.

Behaviour Problems in Retarded Children with Special Reference to Down's Syndrome
TLDR
Deviant behaviour was markedly more common in both sets of retarded children than in their siblings next in age; 31% of the children with DS and 29% of controls were judged to be well adjusted, while 38% ofthe DS children and 49% ofThe controls had significant behaviour disorder.
The temperament of Down's syndrome infants: a research note.
TLDR
Of the questionnaire characterstics with the mother's rating of her child's temperament shows that the mothers's impressions are more positive, and it is suggested that it can also be reflection of successful coping skills.

TLDR
Results showed that mental age was significantly associated with measures of competence and organization and the involvement of the mother had a significant effect only in decreasing the aimless actions of the Down's syndrome children.
Maternal support for the Down's syndrome stereotype: the effect of direct experience of the condition.
  • C. Rodgers

TLDR
Familiarity with the condition resulted in a broader general stereotype, and mothers of Down's Syndrome children attributed more personality traits to the Down's child than mothers without direct experience of the condition.

TLDR
Comparisons with standardization scores on the difficult dimensions suggested that the Down's syndrome children were more rhythmic, less intense and of more positive mood than children of the same CA and children of similar MA were less withdrawn and more adaptable.

TLDR
Survivors of a prospective study of infants with Down's syndrome were followed up at eight or nine years of age, indicating that the priorities for these families are to help the parents deal with emotional repercussions, to teach communication skills to the child, and to diagnose and treat difficult behaviour.

Patterns of temperament variation in the developmentally delayed preschool population have not been adequately studied. The present paper reports temperament data for children 2 to 41/2 years old: 32
Down's syndrome and toddler temperament.
TLDR
The temperament profiles of infants and toddlers with Down's syndrome were compared with those of a non-handicapped, age reference group and the results provide support for examining the temperament of children with Down’s syndrome as a function of chronological rather than developmental age.

TLDR
In a survey study of psychiatric morbidity, based on a representative sample from the Danish mental retardation register, 44 adults with Down's syndrome were compared with 258 other mentally retarded adults, the DS group functioned better on all parameters.

TLDR
The behavioral characteristics of 18 children with Down's syndrome were evaluated, using a questionnaire developed for assessing the temperament of infants, demonstrating that, in early life, a child with down's syndrome is not stereotyped in behavior.
