Limits to a left hemisphere explanation for specific language impairment.

The hypothesis of unilateral left hemisphere damage as an explanatory model for the neurological basis of specific language impairment (SLI) does not appear to be sufficient for most children with SLI. Children with unilateral brain lesions have been shown to function significantly lower than their neurologically intact peers on a variety of language measures, yet few of the deficits noted are as persistent or severe as those seen in SLI. In at least two instances, however, language symptomatology following unilateral lesions in children does parallel some types of SLI. The first occurs following subcortical damage to anterior grey and white matter structures that typically results in pronounced language and learning disorders. The second parallel lies in the similar developmental course shared by children with "delayed" language and children with known unilateral lesions, whereby language onset and development is slow in the preschool years but normalizes by school age, with minimal long-term language-learning deficits.

Attachment and adolescent psychosocial functioning.

To explore the meaning and function of attachment organization during adolescence, its relation to multiple domains of psychosocial functioning was examined in a sample of 131 moderately at-risk adolescents. Attachment organization was assessed using the Adult Attachment Interview; multiple measures of functioning were obtained from parents, adolescents, and their peers. Security displayed in adolescents' organization of discourse about attachment experiences was related to competence with peers (as reported by peers), lower levels of internalizing behaviors (as reported by adolescents), and lower levels of deviant behavior (as reported by peers and by mothers). Preoccupation with attachment experiences, seen in angry or diffuse and unfocused discussion of attachment experiences, was linked to higher levels of both internalizing and deviant behaviors. These relations generally remained even when other attachment-related constructs that had been previously related to adolescent functioning were covaried in analysis. Results are interpreted as suggesting an important role for attachment organization in a wide array of aspects of adolescent psychosocial development.

The relations of children's dispositional prosocial behavior to emotionality, regulation, and social functioning.

The purpose of this study was to examine the relations of a measure of children's dispositional prosocial behavior (i.e., peer nominations) to individual differences in children's negative emotionality, regulation, and social functioning. Children with prosocial reputations tended to be high in constructive social skills (i.e., socially appropriate behavior and constructive coping) and attentional regulation, and low in negative emotionality. The relations of children's negative emotionality to prosocial reputation were moderated by level of dispositional attentional regulation. In addition, the relations of prosocial reputation to constructive social skills and parent-reported negative emotionality (for girls) increased with age. Vagal tone, a marker of physiological regulation, was negatively related to girls' prosocial reputation.

Posttraumatic stress, family functioning, and social support in survivors of childhood leukemia and their mothers and fathers.

Psychological sequelae are examined in 130 former childhood leukemia patients and 155 comparison participants and their parents. The major dependent variables are symptoms of anxiety and posttraumatic stress, family functioning, and social support. Multivariate analyses of covariance indicated significantly more posttraumatic stress symptoms in mothers and fathers of childhood leukemia survivors (p < .001) and no differences between survivors and peers. There were no significant group differences for family functioning or social support, although they were associated with anxiety and posttraumatic stress outcomes. Current child age, age at diagnosis, and months off treatment were not significantly correlated with outcome. These findings document the long-term impact of childhood cancer treatment on parents. The lack of significant differences for survivors argues for further attention to the relevance of posttraumatic stress disorder for childhood cancer survivors. The clinical implications are that psychological interventions are needed during and after cancer treatment.

The development of the Comprehensive Addiction Severity Index for Adolescents (CASI-A). An interview for assessing multiple problems of adolescents.

The Comprehensive Addiction Severity Index for Adolescents (CASI-A) is a 45 to 90-minute comprehensive, semi-structured clinical interview for evaluating adolescents who present for treatment at various provider agencies. CASI-A modules and their individual items were selected and revised based on theory, clinical wisdom, and adolescent experiences obtained during pilot interviews and focus groups. The CASI-A assesses known risk factors, concomitant symptomatology, and consequences of adolescent alcohol/drug use within seven primary areas of functioning: education status, alcohol/drug use, family relationships, peer relationships, legal status, psychiatric distress, and use of free time. The CASI-A is not a diagnostic or screening instrument, but rather a clinical assessment tool that obtains clinically pertinent information designed to guide treatment planning and to evaluate treatment outcome. The CASI-A's design makes it suitable for administration in a variety of settings, for repeat administration at posttreatment follow-up evaluations, and for assessment of virtually all adolescents in treatment regardless of their admission problem. Overall, the CASI-A has encouraging but preliminary evidence of validity and internal consistency. Information collected soon after admission during administration of the CASI-A by nonclinical interviewers corresponded quite well with that obtained over the course of the adolescent's treatment stay by the entire treatment team. Revisions to the instrument are being made in those areas where correspondence between information on the CASI-A and that extracted from clinical records dropped below 75%, or in those early subscales, where alpha coefficients dropped below .6. As a result of the encouraging results reported in this paper, we are beginning additional psychometric testing, refining the proposed scoring system, and developing a computerized data entry, scoring, and report system.

Relation between quality assessment and utilization review in a functioning PSRO.

The Utah State Medical Association, through its peer-review foundation, the Utah Professional Review Organization, has implemented an integrated system of utilization reveiw and quality assessment linked to a program of continuing education. Nurse co-ordinators, employed by the Organization, screen all hospitalized patients covered by Titles XVIII, XIX and V as well as by subscribing private insurers. Approximately 10 per cent of hospitalized patients do not meet peer-generated criteria for admission review or length of stay and are screened out for peer review, The nurse co-ordinators collect data for retrospective quality assessment, identifying targets for continuing medical education. Preliminary data support the cost effectiveness of such a review program. Continuing qualtiy audit will test the effectiveness of education programs.

Breast and cervical cancer screening in minority populations: a model for using lay health educators.

Although mammography and the Pap smear have significantly reduced US deaths related to breast and cervical cancers, screening prevalence and survival rates for both diseases are disproportionately lower among minority women. This model program outlines techniques for recruiting and training minority women to serve as lay health educators who can effectively deliver preventive health care information to their peers. Lay health educators have three primary functions: to serve as mediators between minority women and health agencies, to establish a social network, and to offer social support. When properly recruited and trained, these educators can bridge the gap between health professionals and the community as well as help health professionals to better understand community and individual concerns about cancer. The goal is to increase the detection, prevention, and treatment of breast and cervical cancers in minority communities and thus decrease related deaths. An ongoing intervention by the Arizona Disease Prevention Center, targeting Yaqui Indian and Mexican-American women aged 35 and older, illustrates specific elements of the model.

Parent interview findings regarding the impact of cystic fibrosis on families.

An assessment of the impact of cystic fibrosis (CF) was conducted with 43 families. Semistructured parental interviews on family functioning, parent-child interactions, sibling and peer relationships, and medical issues were coded by two independent raters to identify "major," "minor", or "no" problems. Of the 62 questions presented, only 8 were viewed by more than 10% of parents as "major problems." The impact of hospitalization upon parents was the most prevalent "major problem." Parental communication was a "major problem" for 28% of the mothers but for only one father. Ten to 15% of the parents described "major problems" related to: their marital relationship, accepting the illness, feeling they should do more for their child with CF, feeling their other children had been deprived or complained about inattention, or their relationship with the ill child's grandparents. While most families were generally coping successfully, health care professionals should be alert to specific areas of potential problems.

Use of peer ratings to assess sociability among inpatients with severe psychiatric disorders.

OBJECTIVE: A critical component of inpatient treatment for persons with severe psychiatric disorders is an evaluation of their social impairments. Most existing methods for such evaluations involve staff input and can be both time-consuming and expensive. This paper reports on the use of peer ratings as a method for assessing sociability, an aspect of social functioning in this clinical population. METHODS: Thirty-two inpatients with severe psychiatric disorders who had spent an average of 18 months on an inpatient unit in a state facility rated the popularity of their inpatient peers by completing a 7-point scale measuring how much they enjoyed visiting with each patient. The reliability of peer ratings and their association with staff ratings of patients' behavior on the unit were assessed. RESULTS AND CONCLUSIONS: The peer ratings had excellent test-retest reliability and were highly associated with staff members' independent evaluations of patients' behavior. Peer ratings appear to have promise as a measure of social functioning among inpatients with severe psychiatric disorders.

Multicenter clinical research in adult critical care.

OBJECTIVE: To describe the development, organization, and operation of several collaborative groups conducting investigator-initiated multicenter clinical research in adult critical care. DESIGN: To review the process by which investigator-initiated critical care clinical research groups were created using examples from Europe, Australia, the United States, and Canada. Various models of group structure and function are discussed, highlighting complementary approaches to protocol development, multicenter study management, and project funding. DATA SOURCES: Published peer review research and unpublished terms of reference documents on the structure and function of these groups. DATA SYNTHESIS: The overall goal of clinical critical care research groups engaged in multicenter studies is to improve patient outcomes through conducting large, rigorous investigations. Research programs we reviewed included the following: a) multicenter epidemiologic studies and surveys; b) technology evaluations of mechanical ventilation; c) investigations focused on three priority fields (acute lung injury, infection, and acute brain injury); d) a series of randomized trials of treatments for one syndrome (acute respiratory distress syndrome); and e) diverse methodologies addressing several clinical problems. The structure and function of these research groups differ according to their historical development, research culture, and enabling resources. Specific protocols emerge from clinical questions generated by investigators or from collectively prioritized research agendas. Project funding includes government support, peer-review grants, intensive care foundations, industry, local hospital funds, and hybrid models. Infrastructure for study management varies widely. CONCLUSIONS: Several national and international groups have engaged in investigator-initiated multicenter critical care research. The development, organization, and operational methods of these groups illustrate several collaborative models for clinical investigations in the intensive care unit. Common characteristics of these groups are a cohesive spirit, a sense of mission to achieve shared research goals, and acknowledgment that such an organization is much more than the sum of its parts.

Functional status as an overall measure of health in adults with cystic fibrosis: further validation of a generic health measure.

We studied the validity of a generic health measure in a population with a chronic, life-shortening illness. Thirty-seven adults with cystic fibrosis (CF) and 46 of their healthy peers completed a questionnaire which included 12 questions on functional status from the RAND Health Insurance Study. For the CF group, the questionnaire and a medical chart review yielded data on 7 additional health variables, including pulmonary function. After data collection, members of the CF group were followed for 5 years, by which time 11 had died. The functional status of the CF group was significantly lower than that of the comparison group. Within the CF group, functional status correlated significantly with 6 of the 7 other health variables. Analysis using the Cox proportional hazards model showed that functional status alone was a significant (p less than 0.001) predictor of a CF subject's survival time; in a multivariate model a non-significant trend suggested that lowered functional status may be associated with an increased risk of early death even after adjustment for pulmonary function and percent ideal body weight. These results extend previous findings and suggest that functional status can be used as an overall measure of health in a wide variety of studies.

Behavioral and autonomic responses to peer separation in pigtail macaque monkey infants.

Brief maternal separations of young nonhuman primates have been used extensively to study the behavior and physiology of attachment, loss, and bereavement. The physiological responses to the loss of alternative attachment figures, such as peers, is less well documented in nonhuman primates. This study examined both autonomic and behavioral responses of peer-reared pigtail macaque infants to separation. Eight infants were removed from their mothers at birth and reared in four peer pairs. At 6 months of age, each monkey was implanted with a multichannel biotelemetry device which transmitted heartrate, body temperature, EEG, EMG, and EOG. Blood was collected twice weekly for immunological assessment. Behavioral and physiological data, including sleep, were collected for 1 week of baseline, 2 weeks of separation, and 1 week of reunion. Behavioral and physiological results indicated agitation but not depression following separation from their peer attachment figures. We found reduced mitogenic responses to pokeweed consequent to peer separation, suggestive of altered B-cell function. REM variables were the only sleep measures affected by the separation, and were suggestive of agitation but not depression.

Social problems associated with ADHD vs. ODD in children referred for friendship problems.

Four groups were composed of children referred for friendship problems (age range: 6 to 12 years old). One group was diagnosed with both Attention Deficit Hyperactivity Disorder (ADHD) and Oppositional-Defiant Disorder (ODD), one group with ADHD only, one group with ODD only and one group with neither disorder. Parents and teachers were given questionnaires to rate the social behavior of each child. The groups differed significantly on one parent scale (Self-control) and one teacher scale (Aggression). Inspection of the items composing these scales suggested that some items measured social relationships with adults while other items measured peer relationships. Subsequent factor analysis separated peer and adult components. Analysis of subscales derived from factor analysis revealed the diagnosis of ADHD was associated with increases in classroom disruption and decreased resistance to provocation by peers, while the diagnosis of ODD was associated with increased in hostility towards peers, decreased resistance to provocation by peers and decreased respect for adults. Limitations of the study were: domains of social functioning assessed, sample size and diversity, and the absence of a comparison group with adequate peer relationships. Social skills programs should target social deficits associated with ODD and ADHD. The scales refined in the present study offer a convenient means of assessing peer dysfunction from the points of view of parents and teachers.

New morbidity-problems and peer relations in a sample of Swedish primary school children: a follow-up from the first to the third grade.

The stability in the new morbidity-problem domains motor skills, reading/writing ability, behavioral-psychological-social function and concentration ability in school, and the stability of peer status and peer preferences as well as relationships between peer status and problems among boys and girls was studied in a sample of 81 Swedish primary school children. The children were rated by teachers and made peer nominations six months after school start, and in the third grade. There was considerable stability in problems, while the stability in peer status was modest. There were marked gender differences. Boys in contrast to girls improved in motor skills from the first to the third grade, and boys had more concentration problems and multiple problems than girls in both grades 1 and 3. In the first grade low peer acceptance in boys was accompanied by low motor skills. In the third grade, low peer acceptance in boys was accompanied by deficient concentration ability and externalizing problems. For girls, few relationships between low peer acceptance and problems emerged Various explanations for these findings are discussed.

Physicians' review of significant interventions by clinical pharmacists in inpatient care.

Clinical pharmacists in this study hospital reported 1027 interventions in patient drug therapy over two time periods of three and two weeks each. When peer-reviewed for clinical significance, 36 of these interventions were deemed significant in terms of saving patients' lives or preserving major organ functions; 983 were judged to improve drug therapy to an acceptable level based on standards of the professional literature (8 recommendations were informational i.e., not clinically significant). These 36 interventions were subjected to an independent, blind review by three practicing physicians who were given the same ranking system for clinical relevance as the one used by the peer reviewers. The physicians independently concurred with the peer reviewers on the two interventions initially ranked as 6 (lifesaving in nature). Of the interventions ranked 5 (preserving major organ functions) by the peer-review group, 53 percent were given a rank of 5 by the physicians. However, the remaining 47 percent were given a rank of 4 (upgrading patient drug therapy to the most appropriate level based on professionally accepted standards). In this era of program evaluation and justification, the process of encouraging other health professionals to review pharmacists' contribution to patient care should not be overlooked.

Contemporaneous and longitudinal prediction of children's social functioning from regulation and emotionality.

Relations of regulation and emotionality to social functioning were examined for 77 children followed from early to middle school age. Parents and teachers reported on children's social behavior, emotionality, and regulation, and children engaged in analogue peer conflict situations (i.e., with puppets). High-quality social functioning was predicted by high regulation and low levels of nonconstructive coping, negative emotionality, and general emotional intensity. Prediction often was obtained across reporters and time, although prediction was strongest within context (home versus school). Moreover, measures of regulation and emotionality frequently contributed unique variance to the prediction of social functioning. Contemporaneous correlations at age 8-10 were similar to those obtained at age 6-8, and prediction of later social functioning from emotionality and regulation at age 4-6 was similar at ages 6-8 and 8-10.

Development of an instrument to measure caring peer group interactions.

The purpose of this study was to develop psychometric properties of the Peer Group Caring Interaction Scale (PGCIS) designed to measure caring during informal peer interactions as experienced by undergraduate nursing students. The PGCIS has two subscales that address caring peer behaviors and interactional events during which students assist their peers in the resolution of specific needs. PGCIS psychometric properties were developed using data from 873 junior students enrolled at 87 BSN schools of nursing. Internal consistency reliability was demonstrated for the 9-item Caring Behaviors and the 7-item Giving Assistance subscales with a coefficient alpha of .91 for each. Findings from an exploratory factor analysis supported the two subscale structure of the PGCIS. The PGCIS scores correlated positively with scores on the Intimacy subscale of the Organization Climate Description Questionnaire (OCDQ) and the Peer Group Interaction Scale and inversely with scores on the OCDQ Disengagement subscale. The findings from this study provide beginning support for the PCGIS as a valid and reliable approach to the measurement of caring in academic settings. Additional studies are recommended to continue the psychometric evaluation of this instrument.

Mastery versus ability appraisal: a developmental study of children's observations of peers' work.

This study was designed to test the hypothesis that there is an age-related shift from mastery enhancement to relative ability assessment in the goal of social comparison. Children at ages 5, 7, and 10 made pictures with stickers under conditions of high or low concern with relative performance (competition/no competition) and high or low procedural ambiguity (free design/copying a drawing). The effects of the manipulations on frequency of glancing at the experimenter and the drawing were similar at all ages; competition enhanced glancing at peers, however, only at ages 7 and 10. The hypothesized shift in the function of social comparison was further supported by age differences in children's explanations for glancing at peers and by the pattern of intercorrelations between glances at the 3 targets and between glances and picture quality. The results indicate how mastery-based comparisons can promote mastery and performance and illustrate some costs older children may pay for their tendency to observe others primarily to assess relative ability.
