Sleep and behavior problems in school-aged children.

OBJECTIVES: The primary purposes of the present study were to survey the prevalence of sleep problems in school-aged children and to examine these associations with parental perception of sleep problems, medical history, and childhood psychopathology. METHODS: Sleep and medical history questionnaires and the Child Behavior Checklist were administered to the parents of 472 children between ages 4 and 12 years receiving routine pediatric care from urban, rural, and suburban pediatric practices. RESULTS: Although sleep problems were reported for 10.8% of the sample during the past 6 months, less than one half of the parents who identified sleep problems reported that they had discussed sleep with their child's pediatrician. The best predictor of current sleep problems was a history of sleep problems before age 2 years. Sleep problems such as snoring, tiredness during the day, and taking excessive time to fall asleep were very common, occurring at least 1 night per week in over 20% of the total sample. Factor analysis of the sleep problems questionnaire resulted in 5 sleep problem factors that accounted for 58.7% of the variance. Specific sleep problem factors include: parasomnias, enuresis/gags, tiredness, noisy sleep, and insomnia. Sleep problem factor scores were differentially associated with medical history variables and measures of childhood psychopathology. Children rated highly on parasomnias were more likely to have frequent falls and to display pica. Parasomnias and noisy sleep were inversely associated with socioeconomic status (SES). Children from lower SES families were rated higher on these factors than children from higher SES families. Enuresis/gags was the only sleep problem factor associated with age. Younger children scored higher on this factor. Duration of naps was highly correlated with age and with bed times during the week and weekends. As expected, younger children were more likely to nap for longer periods and to have earlier bed times. In addition, higher tiredness factor scores were associated with napping and with later bed times during the week and weekend. Boys were much more likely than were girls to have higher scores on enuresis/gags, and higher enuresis/gags scores were associated with an increased prevalence of trauma and falls. Bed times were not associated with any other sleep problem factor score. Children rated highly on tiredness were more likely to have a history of hospitalizations. Tiredness factor scores were strongly associated with the sleep practice of sharing a bed but not with sharing a room. Sharing a room was not associated with any sleep problem factor score. High scores on noisy sleep were associated with allergies, falls frequently, and with sharing a bed. Children with high scores on the insomnias were also more likely to display an increased prevalence of allergies. CONCLUSIONS: Parental perception of global sleep problems was surprisingly common in school-aged children receiving routine pediatric care. Parental reports of their children's sleep problems may be a red flag for specific sleep problems and psychiatric, social, or medical problems. Sleep problems should be queried about during pediatric visits for school-aged children.

Behavioral problems in dementia: a factor analysis of the neuropsychiatric inventory.

The aim of this study was to detect behavioral subsyndromes of the 12-item Neuropsychiatric Inventory (NPI). Cross-sectional data of 199 patients with dementia living in the community were collected. Principal component analysis (with Varimax rotation) was used for factor analysis. Results showed the presence of three behavioral subsyndromes: mood/apathy, psychosis, and hyperactivity. Anxiety was regarded as a separate symptom. The subsyndrome mood/apathy was the most common, occurring in almost 80% of the patients, versus psychosis and hyperactivity, which occurred in 37 and 60% of the patients, respectively.

Behavioral problems masking depression--cultural and clinical survey.

In different cultures depressions are masked by different acting-out behaviors; they vary as to type and frequency and are colored by local customs and social determinants. In Western societies hypochondriasis and psychosomatic disorders are the more common masking processes. The broad spectrum of acting-out behavioral patterns pose diagnostic and therapeutic challenges.

Physiological and behavioral regulation in two-year-old children with aggressive/destructive behavior problems.

A sample of 99 two-year-old children was selected on the basis of parents' responses to two administrations of the Child Behavior Checklist for two- to three-year-olds. Forty-nine of these children displayed symptoms of aggressive/destructive (externalizing) problems that were in the borderline clinical range (labelled "high risk") and 50 children displayed few such symptoms ("low risk"). The children were assessed in a series of laboratory procedures that were intended to be emotionally and behaviorally challenging, during which time heart rate was recorded and behavior was observed. To assess physiological regulation, resting measures of heart period and respiratory sinus arrhythmia (RSA), and heart period change and RSA suppression were derived from these procedures. To assess emotional and behavioral regulation, children's affect and on-task versus types of off-task behaviors were measured. Results indicated that children in the high-risk group did not differ from children in the low-risk group on the resting measure of heart period. Boys displayed lower heart rate than did girls, regardless of risk group. However, boys in the low-risk group differed from boys in the high-risk group in terms of resting measures of RSA. Children in the high-risk group did display significantly and consistently lower RSA suppression (physiological regulation) during the challenging situations than did the children in the low-risk group. High-risk children displayed more negative affect and dysregulated emotion regulation behaviors than did the low risk children. These findings are discussed in terms of the development of behavioral and emotional regulation that underlie adaptive versus maladaptive behavior.

Problem behaviors in 3-year-old children in the United Arab Emirates.

INTRODUCTION: The purpose of this study was to examine the prevalence of behavioral disorders among 3-year-old children in the United Arab Emirates (UAE). Although this type of study exists in the industrialized countries, very few studies have been undertaken in the developing countries. METHOD: Six hundred ninety-four randomly selected 3-year-old UAE nationals were screened using the Child Behaviour Checklist for Ages 2-3. RESULTS: Of the children in the study, 10.5% had scores in the clinical range. By using clinical interviews in stage 2 of high-scoring children and random samples of children with normal scores, the weighted prevalence for a clinically significant disorder in behavior was estimated to be 9.94%. A number of putative risk factors were identified, including perinatal factors, adverse family factors, and a positive family history of mental health problems. DISCUSSION: The prevalence of disordered behavior in this Arab culture and its risk factors are similar to those in developed countries. However, certain unique sociocultural determinants were also identified that have implications for the early detection of disordered behavior and care of children with disordered behavior.

Parents and peer group as mediators of the effect of community structure on adolescent problem behavior.

Used a sample of 207 single-parent families residing in 104 small, Midwestern communities to test hypotheses regarding the link between community context and adolescent conduct problems and psychological distress. For boys, community disadvantage had a direct affect on psychological distress, while it indirectly boosted the probability of conduct problems by disrupting parenting and increasing affiliation with deviant peers. Community disadvantage was unrelated to the deviant behavior or emotional well-being of girls. Proportion of single-parent households in the community had a direct effect on girls' conduct problems. It also contributed indirectly to girls' conduct problems by increasing the probability of involvement with deviant peers. Possible explanations for these gender differences are provided.
