Longitudinal Studies of Anger and Attention Span: Context and Informant Effects

JOURNAL OF PERSONALITY, Issue 2 2010
Jungmeen Kim
ABSTRACT This study examined stabilities of informant and context (home vs. classroom) latent factors regarding anger and attention. Participants included children from the National Institute of Child Health and Development Study of Early Child Care and Youth Development who were measured at 54 months, first grade, and third grade. Latent factors of anger and attention span were structured using different indicators based on mothers', fathers', caregivers', teachers', and observers' reports. We used structural equation modeling to examine the autoregressive effects within a context (stability), the concurrent associations between home and classroom contexts, and informant effects. The results indicated that for both anger and attention (1) there were significant informant effects that influenced stability in a context, (2) there was higher stability in home context than nonhome context, and (3) stability within a context increased over time. The findings suggested that anger was more prone to context effects and informant effects than attention. [source]

Rates of adherence to pharmacological treatment among children and adolescents with attention deficit hyperactivity disorder

Abstract Pharmacological intervention, mainly with psychostimulants, alone or with psychotherapy or behavioural modification, was found to be effective in increasing sustained attention span, improving concentration, reducing hyperactive behaviour and improving areas of academic deficits in children and adolescents with the diagnosis of attention deficit-hyperactivity disorder (ADHD). Despite their proven efficacy, noncompliance of the children and adolescents to the prescribed medication presents serious problems to patients and health care providers alike. Objective To investigate the rate of adherence to prescribed medication in a clinically referred sample of children and adolescents diagnosed as having ADHD. In addition, the stability of reports of adherence over a 3 month period was explored. Method Fifty-one children and adolescents (males: n,=,42; females: n,=,9) between the age of 7 years and 16.6 years diagnosed with ADHD and their parents were administered a children behaviour checklist, a teacher report form scale and a compliance with treatement opinion and attitude scale. Results There were very high reports of adherence by children to prescribed medications for ADHD with rates of compliance greater than 70%. Correlation between the children and adolescents' reports and the parents' reports revealed high agreement both at the end of week 1 and at the end of the study (week 12). There were also findings of stability of adherence reports over a 3 month period. Conclusion The results of this study documented high rates of adherence to medication prescribed for symptoms of attention deficit hyperactivity disorder in a sample of children and adolescents. Their reports of adherence were well correlated with parents' reports. Several factors were found to be related to the high level of adherence. Copyright © 2002 John Wiley & Sons, Ltd. [source]

Development of the Nursing Outcome (NOC) Label: Hyperactivity Level

JOURNAL OF CHILD AND ADOLESCENT PSYCHIATRIC NURSING, Issue 3 2005
Carol L. Caldwell MS
TOPIC:,Hyperactivity, a persistent, severe pattern of inattention or impulsivity, places children at risk for impaired functioning in many developmental areas. This behavior is characterized by short attention span, low frustration tolerance, impulsivity, distractibility, and increased physical activity. Responses from multiple sources in the child's environment must be monitored to manage childhood hyperactivity. PURPOSE:,Success at school, in peer relationships, and parent-child interactions is frequently affected by hyperactivity. Using a focus group approach, a Nursing Outcomes Classification (NOC) label, definition, and indicators were developed for Hyperactivity Level. SOURCES:,Review of the literature allowed for a content analysis approach and conceptualization of hyperactivity at several levels. CONCLUSION:,Twenty three (23) measurable indicators were formulated and refined into conceptually and clinically coherent outcomes. Clinical relevance and utility were presented through a case study approach. [source]

The temperament of pre-term, low birth weight infants and its potential biological substrates

RESEARCH IN NURSING & HEALTH, Issue 6 2004
Sandra J. Weiss
Abstract Temperament profiles of pre-term, low birth weight (LBW) infants were assessed at 6 months of age using standardized norms from the Revised Infant Temperament Questionnaire (RITQ). The contributions of perinatal risk, ethnicity, and gender to various temperament dimensions were examined. The sample included 152 infants with a mean birth weight of 1687 g and a mean gestational age of 31 weeks. Eighty percent of the infants were classified as having temperaments that were difficult to manage. Irregularity of the infants' biorhythms, slowness in their ability to adapt to changes, and distractibility were the most problematic. Birth weight, gestational age, and gender were not associated with temperament. Perinatal morbidity was related to the temperament dimension of infant persistence, with implications for the infant's attention span and task performance. Euro American infants were rated as more persistent and less intense in emotional expression than were infants of other ethnic groups. Results suggest the need for a more direct assessment of the effects of neurobiological processes on development of temperament phenotypes and for measurement of temperament that is socioculturally appropriate. © 2004 Wiley Periodicals, Inc.

Unsolved problems in observational astronomy.

ASTRONOMISCHE NACHRICHTEN, Issue 6-8 2004

Abstract The existence of rapidly slewing robotic telescopes and fast alert distribution via the Internet is revolutionizing our capability to study the physics of fast astrophysical transients. But the salient challenge that optical time domain surveys must conquer is mining the torrent of data to recognize important transients in a scene full of normal variations. Humans simply do not have the attention span, memory, or reaction time required to recognize fast transients and rapidly respond. Autonomous robotic instrumentation with the ability to extract pertinent information from the data stream in real time will therefore be essential for recognizing transients and commanding rapid follow-up observations while the ephemeral behavior is still present. Here we discuss how the development and integration of three technologies: (1) robotic telescope networks; (2) machine learning; and (3) advanced database technology, can enable the construction of smart robotic telescopes, which we loosely call "thinking" telescopes, capable of mining the sky in real time.
