Abstract
The effects of gradient levels of perinatal morbidity on school outcomes have been investigated at age 12 in four preterm groups, classified as healthy (no medical or neurological illness), medical morbidity, neurological morbidity, and small-for-gestational-age (SGA), and a full-term comparison group. Teachers report on academic competence, social skills, and problem behaviors. Data on school type, classroom setting, and school service use are gathered from school records. Preterm groups are found to be equivalent to full-term peers in social skills and problem behavior. Preterm groups with neurological and SGA morbidity have the lowest academic competence scores. Unexpectedly, preterm infants with medical morbidity have higher academic competence scores compared with the other preterm groups. School service use increases with greater perinatal morbidity and is contingent on multiple rather than single indicators of perinatal morbidity. Continued monitoring of preterm infants through early adolescence will ensure that appropriate school services and resources are available to maximize their school success.

Abstract
INTRODUCTION Birth weight often is used to predict how preterm infants will grow, but scant attention has been paid to the effect of neonatal morbidities on growth trajectories. We investigated birth weight and neonatal morbidity in preterm infants' growth to age 12 years. METHOD A five-group, prospective, longitudinal study was conducted with 194 infants: 46 full term; 29 healthy preterm without morbidity; 56 preterm with medical illness (MPT); 34 preterm with neurologic illness; and 29 preterm small for gestational age (SGA). Height, weight, and body mass index were measured at six ages. RESULTS The full-term group had greater height than the preterm groups to age 8 years, when healthy preterm and MPT groups caught up. Only the SGA group had smaller height at age 12 years. The MPT, preterm with neurologic illness, and SGA groups had lower weight through age 12 years. Body mass index was appropriate for preterm groups by age 4 years. Across time, neonatal morbidity had a significant effect on height and weight trajectories. Birth weight was significant for weight trajectories only. DISCUSSION With variation in growth trajectories, details of neonatal morbidity in health history interviews will inform child health assessments.

Abstract
OBJECTIVE This study compared the effects of immediate (ICC) and delayed (DCC) cord clamping on very low birth weight (VLBW) infants on 2 primary variables: bronchopulmonary dysplasia (BPD) and suspected necrotizing enterocolitis (SNEC). Other outcome variables were late-onset sepsis (LOS) and intraventricular hemorrhage (IVH). STUDY DESIGN This was a randomized, controlled unmasked trial in which women in labor with singleton fetuses <32 weeks' gestation were randomly assigned to ICC (cord clamped at 5-10 seconds) or DCC (30-45 seconds) groups. Women were excluded for the following reasons: their obstetrician refused to participate, major congenital anomalies, multiple gestations, intent to withhold care, severe maternal illnesses, placenta abruption or previa, or rapid delivery after admission. RESULTS Seventy-two mother/infant pairs were randomized. Infants in the ICC and DCC groups weighed 1151 and 1175 g, and mean gestational ages were 28.2 and 28.3 weeks, respectively. Analyses revealed no difference in maternal and infant demographic, clinical, and safety variables. There were no differences in the incidence of our primary outcomes (BPD and suspected NEC). However, significant differences were found between the ICC and DCC groups in the rates of IVH and LOS. Two of the 23 male infants in the DCC group had IVH versus 8 of the 19 in the ICC group. No cases of sepsis occurred in the 23 boys in the DCC group, whereas 6 of the 19 boys in the ICC group had confirmed sepsis. There was a trend toward higher initial hematocrit in the infants in the DCC group. CONCLUSIONS Delayed cord clamping seems to protect VLBW infants from IVH and LOS, especially for male infants.

Abstract
The increased numbers of low birth weight (LBW) survivors has raised questions about the direct association between LBW and later diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) in early childhood. A longitudinal data set was used to determine the relationship among perinatal morbidity and medical and neurological status during the toddler period (18 and 30 months) with lower attention and higher activity, cardinal features of ADHD at age 4. The sample of 39 full term and 149 preterm infants were recruited at birth. Infants were assigned to 1 of 5 groups based on perinatal morbidity. Medical and neurological status were classified as normal, suspect, or abnormal at 18 and 30 months. At age 4, five measures of attention and activity were gathered from parents and independent examiners. Multivariate analysis of variance (MANOVA) showed significant effects of perinatal morbidity, birth weight, gestational age, gender, socioeconomic status at infancy, and toddler medical and neurological status with lower attention and higher activity at age 4. Prematurity, perinatal illness, and later medical status are early markers for preschool behaviors associated with clinical diagnosis of ADHD.

Abstract
The concepts of risk and vulnerability are frequently the subject of nursing scholarship but lack semantic and conceptual clarity in the nursing literature. Using empirical evidence from 6 research studies, the authors define the concepts of risk and vulnerability, apply shared definitions to each of the study populations, and discuss 3 types of responses to risk observed in the research setting. This collaborative effort by nursing scholars advances conceptual clarity of risk and vulnerability for the development of nursing knowledge. Further, the examination of risk responses has the potential to link the various perspectives of risk and vulnerability common in nursing and generate nursing practice implications explored in this review.

Abstract
OBJECTIVE This pilot study's aim was to establish feasibility of a protocol for delayed cord clamping (DCC) versus immediate cord clamping (ICC) at preterm birth and to examine its effects on initial blood pressure and other outcomes. STUDY DESIGN A randomized controlled trial recruited 32 infants between 24 and 32 weeks. Immediately before delivery, mothers were randomized to ICC (cord clamped at 5 to 10 seconds) or DCC (30- to 45-second delay in cord clamping) groups. RESULTS Intention-to-treat analyses revealed that the DCC group were more likely to have higher initial mean blood pressures (adjusted OR 3.4) and less likely to be discharged on oxygen (adjusted OR 8.6). DCC group infants had higher initial glucose levels (ICC=36 mg/dl, DCC=73.1 mg/dl; p=0.02). CONCLUSION The research design is feasible. The immediate benefit of improved blood pressure was confirmed and other findings deserve consideration for further study.

Abstract
The purpose was to examine a model that incorporates cumulative medical risk at age 4 and distal and protective processes at age 8 to assess school-age competency outcomes of cognition, school achievement, and socioemotional well-being in a sample of preterm children born at various degrees of medical risk. Cumulative medical risk and distal protective and proximal maternal protective processes were constructed into indexes. Hierarchical multiple regression analysis were performed entering the cumulative medical risk index first, followed by distal and proximal protective processes in the next two steps to test the effect on cognitive, academic, and socioemotional competence. For participants, 151 preterm and 39 full-term infants were recruited at birth into a prospective longitudinal study and followed until age 8 with a 97% retention rate. Children were stratified by birth weight and socioeconomic status. The hypotheses were supported. Significant main effects for cumulative medical risk and distal and proximal protective processes in all competency outcome models are key findings. The addition of protective processes was small to moderate in effect (6%-18%) yet clinically significant. These findings illustrate the advantage of applying cumulative medical risk and protection approach to better understand school-age outcomes. Multiple risk and protective models emphasize the joint occurrence of individual contextual processes in the understanding of competence outcomes in high-risk children.

Abstract
BACKGROUND Hypertrophic cardiomyopathy is recognized in infants of diabetic mothers, and when it occurs it is generally benign and transient. We describe a case of fetal cardiac death caused by hypertrophic cardiomyopathy in an infant of a diabetic mother. CASE Hydrops fetalis caused by hypertrophic cardiomyopathy resulted in the death of a macrosomic male fetus of a young woman who had well-controlled diabetes mellitus and was treated with insulin therapy during pregnancy. CONCLUSION It is important to monitor fetal heart function in macrosomic infants of diabetic mothers. Hypertrophic cardiomyopathy might explain otherwise unexplained fetal deaths in women with diabetes.

Abstract
OBJECTIVE The purpose of this prospective longitudinal study was to examine neurocognitive and school performance outcomes of low birth weight infants with reference to neonatal morbidity and socioeconomic status. We further evaluated the cognition and school performance based on their neurologic status at the time of assessment. METHODS One hundred eighty-eight children (39 healthy full-term and 149 preterm infants) were classified into 4 subgroups based on their neonatal medical status: healthy, sick (without neurologic complications), small for gestational age, and neurologically compromised infants. Neurologic status was classified as normal, suspect, or abnormal at hospital discharge, 18 months, 30 months, 4 years, and 8 years of age. Socioeconomic status, cognitive, and school performances were assessed. RESULTS Neurologically, both full-term and healthy preterm groups did well during the 8-year period. There were significant fluctuations between suspect and abnormal neurologic classifications among the 3 preterm groups with neonatal complications. Preterms with neurologic abnormality during the neonatal period did the poorest with 45% of the group remaining abnormal at 8 years of age. Children who were neurologically normal had higher cognitive scores at ages 4 and 8 than those categorized as suspect or abnormal. Preterm infants with neurologic abnormality required significantly more academic resources in the school. Reading and math achievement scores were the lowest for the preterm groups classified as neurologically suspect or abnormal. CONCLUSIONS Neonatal morbidities exert a significant impact in neurologic outcomes among preterm children during the 8 years of assessment. Compromised neurologic status adversely affects cognitive and school performances. Neonatal medical status is an important variable indicating neurocognitive and school performance outcomes in low birth weight infants.

Abstract
BACKGROUND This study was undertaken to derive and validate a short form parent-completed questionnaire to measure health-related quality of life (HRQL) in pediatric asthma patients. OBJECTIVE The objectives of this study were to (1) use stepwise analysis to derive a shorter questionnaire from the original long-form questionnaire and (2) determine the tradeoff in precision between the long- and short-form surveys. METHODS One hundred eighty-one pediatric asthma patients were enrolled from 4 sites. A parent of each patient completed a general and an asthma-specific questionnaire during routine office visits from June 1995 to January 1997. The questionnaire included the Child Health Questionnaire Parent Form 50, a general HRQL survey, and a 17-item asthma-specific battery assessing daytime symptoms, nighttime symptoms, and functional limitations. All scales were scored from 0 to 100, with higher scores indicating better HRQL. Analysis of variance models were used to derive short-form scales from the 17-item long-form scales, and the final asthma-specific short-form scale structure was confirmed with use of stepwise regression. Scale reliability was assessed with Cronbach's alpha. Validity of the short-form questionnaire was assessed by comparing mean scale scores according to the level of asthma severity defined by several clinical criteria. Asthma severity was assessed with use of percent predicted FEV(1), frequency and type of symptoms, parent rating of disease severity, physician rating of disease severity, and resource use (emergency department use and hospitalizations). The relative validity of each of the short-form scales was measured by comparing the proportion of variance explained by each of the short-form scales compared with the respective long-form scales. RESULTS The 17-item asthma-specific battery was reduced to 8 items, the Integrated Therapeutics Group Child Asthma Short Form. The daytime and nighttime symptom scales for each contain 2 items and the functional limitations scale 4 items. Reliability was greater than 0.70 for each of the short-form scales. The absence of ceiling and floor effects indicates each scale's ability to detect changes at both low and high levels of functioning. Lower (poorer) mean HRQL scores for severe cases compared with mild cases, for all disease severity indicators, demonstrated clinical validity. Relative validity estimates, comparing the proportion of explained variance of the short-form scales with that of the long-form scales, ranged from 0. 85 to 1.20, indicating a similar ability to measure change. CONCLUSIONS This study documents the development of a brief, multidimensional, 8-item questionnaire for measuring HRQL in pediatric asthma patients. The brevity of the questionnaire makes it practical for use in practice settings and to monitor patients.

Abstract
This study evaluated the feasibility and psychometric properties of self-completed and telephone interview versions of a patient health-related quality-of-life (HQL) questionnaire for Parkinson's disease that included the SF-36 Health Survey (SF-36), the Parkinson's Disease Questionnaire (PDQ-39), and the Medical Outcomes Study Sexual Function Survey. Parkinson's disease patients (n = 150) completed the questionnaire twice: once at the study site and once over the telephone in a randomized order. Ninety-four percent of enrolled patients completed the first HQL assessment and 88% completed both assessments. Cronbach's alpha exceeded 0.70 for all scales except for the self-completed PDQ-39 Social Support subscale (0.57) and the telephone interview PDQ-39 Social Support (0.60) and Cognitions (0.67) subscales and the SF-36 General Health (0.60) and Social Function (0.61) subscales. There were no statistically significant differences in mean HQL scale scores across the two modes of administration. Mean scores for 3 of the PDQ-39 subscales and the Summary Index were significantly poorer (p < 0.05) for patients at later clinical stages. Similarly, patients with dyskinesias reported significantly poorer scores for 4 of the PDQ-39 subscales and the Summary Index and patients with self-reported comorbidities reported poorer SF-36 Physical Function and General Health subscale scores than patients without dyskinesias and comorbidities, respectively. This study suggests that the self-completed and telephone interview versions of the patient HQL questionnaire are feasible and valid for future clinical trial applications.

Abstract
Control, as an aspect of maternal interaction, has been found to be an important component to optimal child development. Maternal control style is defined as a mother's tendency to be controlling or supportive of her child's autonomy. The relationship between two types of maternal characteristics, proximal and distal, and maternal control style was investigated in a sample of 184 mothers and their 4-year-old children. Global ratings of videotaped data of two problem-solving tasks were made on a 5-point scale. An optimal maternal control style was associated with higher levels of the distal maternal characteristics of maternal education, age, occupation, and higher levels of the proximal characteristics of maternal responsivity and involvement. A hierarchical regression model explaining 26% of the variance in maternal control style scores supports the importance of both types of maternal characteristics. The results are discussed in relation to the methodology and the theoretical framework of role.

Abstract
The twofold purpose of this study was to compare motor function in preschool children born with varying degrees of medical risk and to determine the independent contribution to motor function of three domains of ecological influence. One hundred and eighty-four 4-year-old children and their mothers participated. Three predictor sets, proximal, distal, and child, and four motor outcomes were measured by multiple methods. Children born prematurely scored lower on all dimensions of motor function. Prematurity complications had a different effect on motor function. Hierarchical regression models explained 16-40% of motor score variance. Results are discussed in relation to heterogeneity of prematurity and ecological influences on motor outcomes.

Abstract
BACKGROUND The influence of specific maternal interaction patterns as compensatory mechanisms in promoting development of medically high-risk children has been understudied. OBJECTIVES To investigate the association of three maternal interaction patterns, maternal responsivity, involvement, and control style, with preschool competency in a medically heterogeneous sample. METHOD Children (N= 184) and their mothers participating in a prospective longitudinal study were assessed in a laboratory protocol and home visit. The methods of measurement were maternal self-report, global rating scales, interview, and nationally standardized instruments. RESULTS Evidence of a maternal compensatory mechanism was exhibited in mothers' higher involvement with their children who were born at high medical risk (F(1,183) = 6.26, p = .01). Mothers of the most competent children demonstrated higher maternal responsivity, involvement, and more appropriate control than mothers of children who were not as competent. In hierarchical regression models, the three maternal interaction patterns were significant predictors after perinatal risk and maternal education were controlled explaining 29-37% of the variance in child competence scores. CONCLUSION These findings imply that differential child outcomes are associated with specific maternal interaction patterns. It suggests that a combination of diverse information revealed in specific maternal interaction pattern is needed to predict cognitive, linguistic, and problem-solving competencies. Future research should consider individual differences in mother-child interaction patterns in order to isolate their significance for optimal child development.

Abstract
OBJECTIVE To compare resource use by diagnostic outcome among hospital admissions during which tuberculosis (TB) was suspected. DESIGN Retrospective study based on chart review and microbiology laboratory data. SETTING The department of medicine in a municipal hospital serving central Brooklyn, New York. PARTICIPANTS We identified all adult admissions in 1993 during which TB was suspected. We assigned each admission to one of four mutually exclusive groups defined by the results of microbiological tests (acid-fast bacilli [AFB] smear and culture): culture-positive and smear-positive (C+S+); culture-positive and smear-negative (C+S-); culture-negative and smear-positive (C-S+); or culture-negative and smear-negative (C-S-). Each admission was divided into two separate periods to which the utilization of medical resources was assigned: the diagnostic and the postdiagnostic periods, which were separated by the date of receipt of the first definitive culture report. RESULTS Data on 519 admissions (93 C+S+; 57 C+S-; 30 C-S+; and 339 C-S-) were analyzed. Although C+S+ were more likely than other groups to have an admitting diagnosis of TB, approximately one quarter of the admissions without TB (C-S+, C-S-) were admitted with the principal diagnosis of TB. For the four groups, C+S+, C+S-, C-S+, and C-S-, the respective rates of TB isolation and anti-TB treatment, and median lengths of isolation were 98%, 87%, and 34 days; 74%, 74%, and 7 days; 83%, 83%, and 15 days; and 44%, 29%, and 0 days. During the diagnostic period, the rate and length of isolation were similar in the AFB-smear-positive groups (C+S+ and C-S+). We estimated that admissions without culture-proven TB (C-S+ and C-S-) accounted for 3,174 (36%) of the 8,712 days of TB isolation expended and for 65% of the 16,671 days of anti-TB treatment. The vast majority of this resource consumption (2,737 [86%] of 3,174 days of isolation) occurred during the diagnostic period before a definitive culture result was known. CONCLUSIONS Our results suggest that prolonged diagnostic uncertainty and misclassification of cases due to false-positive and false-negative smears are associated with substantial medical-resource consumption. New diagnostic modalities that reduce the period of diagnostic uncertainty could reduce the utilization of resources later found to be unnecessary.

Abstract
BACKGROUND We evaluated health-related quality of life (HQL) in kidney transplant patients participating in a multicenter, prospective, randomized, phase III trial comparing tacrolimus to cyclosporine. HQL data were available for 303 of 412 patients and assessed with the SF-36 Health Survey and six multi-item scales: Current Health, Health Outlook, Health Distress, Fleming Self-Esteem, Bergner Physical Appearance, and Sexual Functioning. METHODS Patients completed surveys at baseline, week 6, and months 3, 6, and 12. The mean change in HQL was evaluated by rejection occurrence and number of hospitalizations. Analysis of covariance was used to model endpoint HQL scores as a function of treatment group and baseline HQL. RESULTS All scales but two met psychometric standards for group-level comparisons. Baseline demographics and HQL scores were not different by treatment. The mean HQL change was lower for patients with rejection compared with no rejection in seven of eight SF-36 scales and three of four remaining supplemental scales. One year after transplantation, study patients were functioning at least as well as half of the general population in Vitality and Role-Emotional Functioning, moving from the 18th percentile of the U.S. population scores to the 50th percentile for Vitality and 54th percentile for Role-Emotional Functioning. Patients improved their percentile ranking by at least 20 points in five of eight SF-36 scales. CONCLUSIONS Patients with kidney disease demonstrate substantial HQL burden before transplantation, and transplantation is associated with substantial HQL improvements. Rejection is associated with less HQL improvement. Endpoint HQL values were significantly different (P<0.05) by treatment, favoring tacrolimus, in the Bergner Physical Appearance scale, which was designed to measure the HQL impact of side effects such as gingival hyperplasia and facial hirsutism on physical appearance.

Abstract
BACKGROUND Many hysterectomies are now performed by a laparoscopically assisted vaginal technique. This procedure is controversial, partly because of concern about cost. We studied hospital charges and costs for the procedure as compared with those for total abdominal hysterectomy and total vaginal hysterectomy in clinically similar groups of patients. METHODS From hospital-discharge data and patients' charts, we identified hysterectomies performed in 1993 and 1994 by 96 surgeons at a community teaching hospital to treat benign conditions. The patients were grouped according to the surgical procedures performed in conjunction with the hysterectomy. Data on hospital charges and cost-to-charge ratios for 64 hospital cost centers were used to assess charges and costs for specific resources, as well as for the hospitalization overall. RESULTS Of 1049 patients studied, 26 percent underwent laparoscopically assisted vaginal hysterectomy, 54 percent underwent abdominal hysterectomy, and 20 percent underwent vaginal hysterectomy. The average hospital stays were 2.6, 3.9, and 2.9 days, respectively, and the mean total charges (facility charges plus professional fees) for the hospitalizations were $6,116, $5,084, and $4,221 (P<0.001 for the comparison of the laparoscopic technique with both other techniques). The mean facility costs were $4,914, $3,954, and $3,116, respectively (P<0.001 for the same comparison), with similar findings in all subgroups. The higher charges and costs for laparoscopically assisted vaginal hysterectomy were due to higher supply costs, particularly when disposable supplies were used, and to longer operating-room time. CONCLUSIONS Despite shorter hospital stays, in-hospital charges and costs for laparoscopically assisted vaginal hysterectomy are higher than for either alternative procedure, because of the disposable supplies that are typically used and the longer operating-room time.

Abstract
OBJECTIVE To determine physician's perceptions about vaginal birth after cesarean section and compare them to the physicians' actual practice experience. STUDY DESIGN Physicians responded to a questionnaire on their perceptions of vaginal birth after cesarean section. Between July 1, 1991, and June 30, 1992, all attempts at vaginal birth after cesarean section were reviewed. All cesarean deliveries were also reviewed to determine which repeat cesarean sections could have been avoided. RESULTS One hundred twenty-four patients attempted vaginal birth after cesarean section, and 95 (76.6%) were successful. Physician perceptions revealed a success rate of 73.6%. Those patients whose labor was induced in their attempt at vaginal birth after cesarean section were less successful (41.9%) than those who did not require induction (88.2%) (P < .001). Upon review, 47% of patients who underwent elective repeat cesarean section did not have a contraindication to a trial of labor. CONCLUSION Physicians had an accurate perception of the success of vaginal birth after cesarean section in their practices. Vaginal birth after cesarean section success rates were consistent with those reported in the literature. Despite a high attempt rate (72.5%) among those eligible for vaginal birth after cesarean section, almost half the patients undergoing a repeat elective cesarean section did not have a contraindication to a trial of labor.

Abstract
This article discusses the costs and benefits of mammographic screening in the workplace. The cost of mammography itself and of diagnostic work-up are two of the largest costs involved. Therefore, the most efficient approach to providing mammography depends on the number of employees receiving mammography; and the diagnostic accuracy of mammography and underlying incidence of breast cancer in the screened population strongly influence the number of suspicious mammograms that are not associated with breast cancer. The health benefit of mammographic screening is due to reduced mortality and morbidity through early detection and more effective treatment, which may also result in economic savings if early-stage cancer is less expensive to treat. However, the total lifetime cost of treating early-stage cancer may be greater than treating late-stage cancer because of improved survival of early-stage patients. Thus, although periodic mammographic screening is not likely to result in overall economic savings, in many populations of working-age women, especially those with identifiable risk factors, screening is cost-effective because the expenditure required to save a year of life through early detection of breast cancer is low compared to other types of health services for which employers commonly pay.

Abstract
The MOS 36-item short-form health survey is a generic, patient-based health assessment tool. It has been used to assess functional outcome for many medical conditions, both acute and chronic. The use of this survey in evaluating the effects of treatment of any specific disease or injury allows comparison of treatments across a broad spectrum of disease categories. The purpose of this study was to see if this assessment tool could 1) be used to identify those patients requiring anterior cruciate ligament reconstruction, 2) detect changes in the patients with treatment over time, and 3) correlate with the commonly used knee assessment scales. The short-form health survey could not identify those patients requiring anterior cruciate ligament reconstructive surgery. However, it did show important and significant changes with treatment (surgical and nonsurgical) over time. There was a significant correlation between the short-form health survey and the Lysholm and International Knee Documentation Committee scores during this study. The addition of the MOS 36-item short-form health survey to our traditional knee ligament evaluation tools is encouraged. Its use will permit the orthopaedic community to demonstrate the value of our treatment of anterior cruciate ligament injuries to health care planners and generalist physicians.

Abstract
OBJECTIVE To use both qualitative and quantitative methods to examine the experience of motherhood during adolescence and to evaluate developmental influences on the concept of maternal role. DESIGN (1) A grounded theory approach was initially used to generate a hypothesis. Focus groups and individual interviews were analyzed for concept and theme. (2) A quantitative method using correlational analysis was used to test the hypothesis generated by qualitative study. A structured interview using five specific, scored questions about self and about motherhood was used to examine the relationship between developmental complexity of responses to questions about self and questions about motherhood. SETTING AND PARTICIPANTS The qualitative study involved group and individual interviews with 42 teenage mothers. The quantitative study involved individual interviews with 25 mothers, ages 14 to 18 years, at an innercity clinic for young parents and their infants. Race and ethnicity were heterogeneous, and 100% received Aid to Families With Dependent Children. RESULTS The major hypothesis generated from the qualitative analysis was that an adolescent mother's conceptualization of her maternal role is related to her own psychosocial and cognitive development. The quantitative study revealed a strong correlation between the developmental complexity of responses to questions about self and the complexity of responses to questions about motherhood (r2 = .81). CONCLUSION The experience of motherhood and the conceptualization of the maternal role in adolescence is related to young mothers' psychosocial cognitive development.

Abstract
OBJECTIVE To determine whether the "goodness of fit" between infant cry characteristics and the mother's perception of the cry is related to developmental outcome at 18 months of age. DESIGN This was a prospective, longitudinal study from birth to 18 months performed in a blinded manner. SETTING The study was conducted in a maternity hospital, including normal and special care nurseries and a laboratory for developmental follow-up. PATIENTS The 121 term and preterm infants and their mothers were selected to meet medical criteria. MEASUREMENT Acoustic analysis of 1-month infant cry and the mother's perception of the same cry was used to divide subjects into four groups representing matches and mismatches between infant cry characteristics and maternal cry perception. Primary outcome measures of cognitive, language, motor, and neurologic outcome were administered at 18 months. Caretaking environment measures were also recorded. RESULTS Statistically significant (P < .05) findings showed that matched groups scored higher on measures of language and cognitive performance than infants in the mismatch groups, with a particular advantage for infants in the matched group in which mothers accurately perceived the higher-pitched cries of their infants. There were no differences between the groups in biologic or sociodemographic factors. Group differences were observed in social support and maternal self-esteem. CONCLUSIONS Matches and mismatches between infant cry characteristics at 1 month and the mother's perception of the cry are related to cognitive and language outcome at 18 months in term and preterm infants. This relation is probably due to transactional processes in which developmental outcome is affected by the clarity of the infants' signals and by the ability of the mother to accurately perceive her infant's signals. The mother's ability to read her infant's cues may be affected by factors such as social support and self-esteem.

Abstract
Maternal self-esteem is examined from theoretical and clinical perspectives. The construct of maternal self-esteem is described, and infant and maternal factors affecting it are delineated. These factors include infant health, maternal perception of infant health, and newborn characteristics. Particular emphasis is placed on maternal perception of the infant's health and behavior. The preterm infant within the context of the special care nursery is used as a clinical illustration, thus bridging the gap from theory to clinical practice. General unit guidelines and clinical intervention strategies, for all disciplines, are suggested to enhance the maternal self-esteem of preterm mothers.
