OBJECTIVE To investigate the associations between children's perceived chest pain severity, somatization symptoms, depressive symptoms, anxiety sensitivity, and maternal somatization symptoms in children and adolescents with noncardiac chest pain (NCCP). METHODS Measures of chest pain and psychosocial functioning were collected from 35 participants (M age(More)
This paper presents and evaluates a method for the construction of long-range and wide-area temporal spatial datasets of daily precipitation and temperature (maximum and minimum). This method combines the interpolation of daily ratios/fractions derived from ground-based meteorological station records and respective fields of monthly estimates. Data sources(More)
OBJECTIVE This study investigated factors related to health care utilization (HCU) among patients presenting to pediatric cardiologists with symptoms of chest pain later diagnosed as noncardiac chest pain (NCCP). METHODS Participants included 67 children and adolescents diagnosed with NCCP and their parent. Measures of HCU, pain severity, and child(More)
OBJECTIVE To examine differences in factors related to health care utilization (HCU) among children eventually diagnosed with noncardiac chest pain (NCCP) or an innocent heart murmur (IHM). METHODS 67 pediatric patients with NCCP and 62 with IHM and their parent/guardian completed paper-and-pencil measures of psychological functioning and past HCU during(More)
Various decision rules have been advanced for evaluation of brain dysfunction with the Luria-Nebraska Neuropsychological Battery in a chronic schizophrenic or schizoaffective disorder psychotic population. The rules of Golden (1981a) produced the highest hit rate of 96% for identification of schizophrenics who had normal neurological examination findings as(More)
OBJECTIVE To examine the occurrence of internalizing symptoms and functional disability in children with noncardiac chest pain (NCCP) compared with children with innocent heart murmurs (IHMs). METHOD 67 children with NCCP (M [SD] age = 12.61 [2.63]; 68.7% Caucasian) and 62 children with IHM (M [SD] age = 12.67 [2.62]; 50% Caucasian) were recruited from(More)
Split-half reliability estimates previously reported for the Luria-Nebraska Neuropsychological Battery (LNNB) summary scales have been uniformly high, but their magnitude depends upon the method of item grouping for the half-tests compared. Coefficient alpha was employed in the current study as it gives the mean of all possible split-half values. Alpha(More)
Reliability analyses were computed for the Luria-Nebraska Neuropsychological Battery (LNNB) summary and localization scales using coefficient alpha as a measure of internal consistency. Separate reliability analyses were carried out for a mixed group of brain-damaged patients and neurologically normal groups of psychotic (schizophrenic or schizoaffective(More)
The 30 scales developed from scalewise factor analyses of the items of the Luria-Nebraska Neuropsychological Battery were subjected to internal consistency analyses by means of coefficient alpha for a mixed brain-damaged group and neurologically normal groups of alcoholic and schizophrenic or schizoaffective disorder patients. Thirty-seven per cent of the(More)
