Adolescent parricide: a comparison with other adolescent murder.

The authors examined the available data for 10 adolescents who had been charged with parricide and compared these with data for matched groups of 10 adolescents charged with murdering another relative or a close acquaintance and 10 charged with murdering a stranger. They found significant differences between parricidal adolescents and other homicidal adolescents on personality, family, social, and follow-up adjustment variables.

Voluntary assent in biomedical research with adolescents: a comparison of parent and adolescent views.

An informed consent and voluntary assent in biomedical research with adolescents is contingent on a variety of factors, including adolescent and parent perceptions of research risk, benefit, and decision-making autonomy. Thirty-seven adolescents with asthma and their parents evaluated a high or low aversion form of a pediatric asthma research vignette and provided an enrollment decision; their perceptions of family influence over the participation decision; and evaluations of risk, aversion, benefit, and burden of study procedures. Adolescents and their parents agreed on research participation decisions 74% of the time, yet both claimed ultimate responsibility for the participation decision. Both rated most study procedures as significantly more aversive than risky. Parents were more likely to rate aspects of the hypothetical study as beneficial and to provide higher risk ratings for procedures. Disagreements concerning research participation decisions and decision-making autonomy have implications for the exercise of voluntary assent in biomedical research.

Ghrelin and bone metabolism in adolescent girls with anorexia nervosa and healthy adolescents.

CONTEXT: Anorexia nervosa (AN) in adolescents is associated with low bone mineral density (BMD) and increases in ghrelin secretion, an orexigenic GH secretagogue that stimulates osteoblast proliferation in vitro. OBJECTIVE: We hypothesized that ghrelin may have independent effects on bone in AN adolescents. STUDY DESIGN, SUBJECTS, AND OUTCOME MEASURES: Frequent sampling was performed overnight every 30 min for 12 h in 23 adolescent AN girls aged 12-18 yr and 21 controls of comparable maturity. Ghrelin, leptin, cortisol, and GH secretion were examined using Cluster and deconvolution. We measured BMD and body composition (dual-energy x-ray absorptiometry) and carboxy-terminal peptide of type I procollagen and N-telopeptide levels. RESULTS: In healthy adolescents, ghrelin secretion strongly predicted BMD; secretory burst mass being the strongest predictor of lumbar spine (LS) bone mineral apparent density (BMAD) (r = 0.66, P = 0.003), LS BMAD z-scores (BMAD-z) (r = 0.59, P = 0.01), hip BMD (r = 0.55, P = 0.02), and hip BMD-z (r = 0.52, P = 0.03). When body composition measures (body mass index, lean and fat mass), and hormonal predictors (GH, IGF-I, cortisol, leptin, and estradiol) were entered into a regression model with ghrelin secretion to determine independent BMD predictors, ghrelin was the strongest predictor of LS BMAD, BMAD-z, hip BMD, and hip BMD-z, contributing to 43, 30, 26, and 19% of the variability, respectively, independent of GH or cortisol effects. Conversely, in AN, ghrelin secretion did not predict LS BMAD or hip-z and weakly predicted LS BMAD-z and hip BMD. Ghrelin did not predict carboxy-terminal peptide of type I procollagen or N-telopeptide/creatinine, which were predicted by GH and cortisol. CONCLUSION: Ghrelin secretion predicts bone density independent of body composition, the GH-IGF-I axis, cortisol, or estradiol in healthy girls but not in those with AN.

Development and validation of the Rapid Estimate of Adolescent Literacy in Medicine (REALM-Teen): a tool to screen adolescents for below-grade reading in health care settings.

OBJECTIVE: The magnitude and consequences of low literacy in adolescent health and health care are unknown. The purpose of this study was to validate the Rapid Estimate of Adolescent Literacy in Medicine (REALM-Teen), a word-recognition test in English that can be used as a brief literacy-screening tool in health care settings. PATIENTS AND METHODS: A total of 1533 adolescents aged 10 to 19 years attending 1 of 5 middle schools, 3 high schools, 1 pediatric clinic, or 2 summer programs in Louisiana and North Carolina participated in face-to-face interviews. Demographic information was solicited, and participants were administered a battery of reading tests, including the REALM-Teen, Wide Range Achievement Test-Revised (WRAT-3), and Slosson Oral Reading Test-Revised (SORT-R). Internal consistency for the REALM-Teen was determined using Cronbach's alpha, and criterion validity was established through correlations with both the WRAT-R and SORT-R. Using reading below grade level (according to SORT-R scores) as an outcome, instrument accuracy and corresponding cutoff scores were calculated by plotting receiver operating characteristic curves and stratum-specific likelihood ratios. RESULTS: Participants were 50% black and 53% female; 34% were enrolled in middle school and 66% in high school. The average time required to administer the REALM-Teen was 3 minutes. Internal consistency was excellent, as was test-retest reliability. The REALM-Teen is strongly correlated with both the WRAT-R and SORT-R. Five reading level categories were identified: 3rd grade and below, 4th to 5th grade, 6th to 7th grade, 8th to 9th grade, and 10th grade and above. Forty-six percent of participants were reading below grade level according to the SORT-R and 28% had repeated at least 1 grade. CONCLUSION: The REALM-Teen is a brief, reliable instrument for assessing adolescent literacy skills and reading below grade level.

Sexual abuse in adolescents--data from a psychiatric treatment centre for adolescents.

OBJECTIVES: To determine the prevalence of sexual abuse in a large sample of adolescent psychiatric patients and to compare sexually abused patients with non sexually abused patients, the latter category including non-sexual physically abused and non-abused patients. DESIGN: A retrospective analysis of the patient records at the William Slater Centre for Adolescents, University of Cape Town Medical School/Groote Schuur Hospital. SETTING: The William Slater Centre (WSC) is an outpatient psychiatric treatment centre for adolescents with emotional and behavioural problems. SUBJECTS: Nine hundred and thirty-four adolescent and young adult patients referred to the WSC in Cape Town from February 1990 to April 1997. METHODS: The WSC Assessment form, a semi-structured interview schedule, was used to focus on depressive symptoms, suicidal ideation and parasuicide, eating disorders, substance abuse, psychosexual history, sexual abuse and physical abuse, and Diagnostic and Statistical Manual i.v. diagnosis. RESULTS: One-third of all patients admitted to the centre from February 1990 to April 1997 reported some form of sexual abuse. More sexually abused patients than expected received a diagnosis of depression. On average sexually abused patients scored higher on depression rating scales than non sexually abused patients. Logistic regression showed that the presence of suicidal symptoms and alcohol use are to some extent independently associated with sexual abuse. CONCLUSION: The problem of sexual abuse among South African youth is confirmed by this study. The association between sexual abuse and depression, suicidal symptoms and alcohol use is supported. The country's dwindling psychiatric services therefore face an increasingly challenging future.

Suicide and suicide attempts in adolescents. Committee on Adolescents. American Academy of Pediatrics.

Suicide is the third leading cause of death for adolescents 15 to 19 years old.(1) Pediatricians can help prevent adolescent suicide by knowing the symptoms of depression and other presuicidal behavior. This statement updates the previous statement(2) by the American Academy of Pediatrics and assists the pediatrician in the identification and management of the adolescent at risk for suicide. The extent to which pediatricians provide appropriate care for suicidal adolescents depends on their knowledge, skill, comfort with the topic, and ready access to appropriate community resources. All teenagers with suicidal symptoms should know that their pleas for assistance are heard and that pediatricians are willing to serve as advocates to help resolve the crisis.

Factor structure of the Reynolds Adolescent Depression Scale in a sample of school-based adolescents.

Depression is a common health problem in the adolescent population. The Reynolds Adolescent Depression Scale (RADS) is used to measure depression in clinical and community adolescent samples. Although there is available evidence for the reliability and validity of the RADS, there is insufficient documentation of its factor structure. This study examined the factor structure of the RADS in adolescent boys and girls (m-144). Internal consistency reliability ranged from .91 to .94 based on grade level, and was .91 for boys and .93 for girls. Factor analysis resulted in a 5-factor solution. Interpretation of factors were as follows: (a) Factor I--generalized demoralization; (b) Factor II--despondency and worry; (c) Factor III--externalized somatocism; (d) Factor IV--anhedonia; and, (e) Factor V--self-worth.

Diagnosis of the polycystic ovary syndrome in adolescence: comparison of adolescent and adult hyperandrogenism.

We performed gonadotropin releasing hormone agonist (GnRHag) tests on 23 consecutive hyperandrogenic girls 9.9-17.5 years of age who were referred to our pediatric endocrinology clinic with symptoms suggestive of PCOS. They were compared to contemporaneously studied groups of adult normal and hyperandrogenic women. We found that hyperandrogenic adolescents had clinical and endocrine features similar to those of hyperandrogenic adults. However, there were some noteworthy unique features of adolescent hyperandrogenism, such as presentation in mid-childhood with premature pubarche and the occasional diagnosis before the age of 10 years. Some differences between adolescents and adults were statistically significant, for example, pelvic ultrasonography was not as helpful in the diagnosis of FOH as it is in adults. Nevertheless, a number of questions about the development of the ovarian dysfunction remain to be answered. For example, we are unable to diagnose ovarian dysfunction before puberty or in early puberty, and the relationship of "physiologic adolescent anovulation" to PCOS remains to be defined.

Self-esteem in adolescence: a comparison of adolescents with diabetes mellitus and leukemia.

This descriptive study examined the self-esteem of adolescents with diabetes mellitus and leukemia. Participants included 22 adolescents with diabetes mellitus and 33 with leukemia. No significant difference was found between the self-esteem of males and females in either group. After the initial diagnosis, over time a decrease in self-esteem in the leukemia group and an increase in self-esteem in the diabetes mellitus group were observed. The adolescents with leukemia who experienced a relapse had moderate self-esteem. Most of the adolescents with leukemia could not attend school because of their illness. The mean scores of self-esteem were high in the diabetes mellitus group and moderate in the leukemia group. In both groups, the mean scores of self-esteem were compared to depressive affect, daydreaming, psychosomatic symptoms, intensity of discussion, and parental interest (subscales in the Rosenberg self-esteem scale). No significant difference was found between the two disease groups. There was a strong and significant correlation between self-esteem and depressive affect in both groups.

Parent-adolescent conflict in early adolescence.

This study explored parent-adolescent conflict during the early years of adolescence (ages 11 to 14). The responses of 357 youths in Grades 6, 7, and 8 to the Issues Checklist (Prinz, Foster, Kent, & O'Leary, 1979) revealed frequent conflicts with parents over a sizable number of issues during this period, peaking in Grade 7 between parents and sons, with exchanges between parents and daughters consistently more than those with sons across the three grades. There was considerable variation in both the frequency and intensity of conflict across specific issues. In addition, a consistent pattern of gender-typing was observed in conflicts between parents and daughters, reflecting traditional gender role stereotypes. The results of this study point to the importance of examining both the frequency and intensity of conflict, the specific issues over which there is conflict, and the gender of the participants in order to more fully understand the nature of parent-adolescent conflict during early adolescence.

Comparison of sacropelvic morphology between normal adolescents and subjects with adolescent idiopathic scoliosis.

Previous studies suggest that the pelvic morphology may be abnormal in adolescent idiopathic scoliosis. This study compares the sacropelvic morphology between normal adolescents and subjects with adolescent idiopathic scoliosis (AIS) in both sagittal and coronal planes. The sacropelvic morphology was assessed from the postero-anterior and lateral standing radiographs of 27 normal adolescents and 29 subjects with AIS presenting a major Cobb angle greater than 30 degrees . Sacropelvic morphology was characterized by 19 parameters in the sagittal plane and 26 parameters in the coronal plane. There was no difference in sacropelvic morphology between the two groups in the sagittal plane. In the coronal plane, significant differences were found for right pelvic length, right iliac height, left and right pubic length, left obturator foramen width, bicristal distance, bituberal distance, biacetabular distance, pubic symphysis width, pelvic inlet, and subpubic angle. There was no significant pelvic asymmetry in AIS subjects. This is the first study that specifically evaluates the sagittal and coronal sacropelvic morphology in AIS. The results suggest that the coronal sacropelvic morphology is distorted in AIS. A longitudinal study is required in order to evaluate the influence of sacropelvic morphology in the progression of AIS.

Comparison of isometric trunk rotational strength of adolescents with idiopathic scoliosis to healthy adolescents.

Trunk rotational strength asymmetry has been suggested in adolescents with idiopathic scoliosis (IS), but is unconfirmed. The sitting isometric trunk rotational strength, at neutral and 18 degrees or 36 degrees of right or left pre-rotation, of a group of healthy adolescent females (CG), n=12, is compared with a group of female adolescents with IS (ISG), n= 14. Torque values were normalized to lean body weight. There is a significant weakness when rotating towards the concavity found in patients with AIS at the 36 lo (p 0.07 marginal), 18 lo (p<0.03) and neutral positions (p<0.02), with no side strength asymmetry found in a cohort of healthy adolescents without AIS.

Comparison of factor-analyzed Adolescent Reinforcement Survey Schedule (ARSS) responses from Japanese and American adolescents.

The Adolescent Reinforcement Survey Schedule (ARSS) was administered to a sample of male and female late adolescent college students from Japan (N = 500). The responses to the ARSS are factor analyzed using a principal component method. The results of the factor-analyzed ARSS from the Japanese sample are compared and contrasted with the results from a previous study (Holmes et al., 1987) in which ARSS was administered to a sample of American male and female college students (N = 231). Both the American and Japanese samples produced 10 interpretable factors. A recommendation is made to replicate the present study with groups of early and mid-adolescents in each culture in order to study shifts in reinforcers during different periods of adolescent development.

Loneliness and alcoholism risk in late adolescence: a comparative study of adults and adolescents.

The Short Michigan Alcoholism Screening Test (SMAST) was administered via phone survey to a random sample of subjects 18 years of age and older in a large metropolitan county. Among late adolescents (aged 18 to 20), lonely females had the highest mean score on the SMAST, indicating a higher degree of alcoholism risk than lonely males and nonlonely males and females. Among lonely females, late adolescents scored higher on the SMAST than any other age group. For males, loneliness did not appear to increase alcoholism risk in the late adolescent age group, but did appear to do so during the early and middle adulthood years. The implications of these findings for mental health professionals and adolescent substance abuse treatment personnel are discussed.

[Suggestions made by adolescents to prevent suicide by adolescents (author's transl)].

738 examination papers were collected from adolescents aged 18 to 21 years on the subject of suggestions for preventing adolescents from committing suicide. The persons examined were female trainees for the nursing profession, consulting-room assistants, trainees in midwifery and male nurses undergoing training. The main reasons for suicide stated were a feeling of having been abandoned, or conflicts between the generations (19% each), whereas the main reasons for attempted suicide were stated to be problems connected with school and profession (24%), as well as unrequited or unhappy love (16%). It is actually true that first sexual disappointments or unhappy love accounted for 37% of 438 attempts at suicide in the city of Zürich within a period of 10 years. Continually recurring suggestions of prevention, both generally and specifically, were heart-to-heart talks with persons of the same age, inclusion of outsiders in the group, promotion of self-concept, and recognition as well as building up the personality of the adolescent concerned. The basic trend noticeable in 12 comprehensive suggestions regarding an overall prevention of adolescent suicide is that parents should not belittle their children's problems and worries, that groups of friends should be built up in early childhood, and that tactful sexual education is mandatory.

Adolescent homicide and family pathology: implications for research and treatment with adolescents.

The origins of serious violence in adolescents has been of concern throughout the century. The number of felony-murder convictions of adolescents on death row in the United States is arguably a warning beacon about the serious nature of juvenile homicide. This article reviews the research on adolescent homicide and highlights significant family variables. The contributions of a family studies perspective for understanding adolescent homicide is discussed and implications suggested.

Selected volunteer adolescents in adolescent group therapy.

Twenty-one adolescents had therapy in a group containing three volunteer adolescents over a period of ten months. Fifteen adolescents came to five sessions or more. A description of the group shows how many of the group members model their behavior and attitudes on those of the volunteers. It is suggested that using volunteers is a useful method of initiating and maintaining a group of adolescents.

[Comparison of the blood levels of insulin and growth hormone in healthy adolescents, adolescents with excessive weight and with hereditary loading with regard to diabetes mellitus].

Changes in insulin and growth hormone secretion were studied in 112 children and adolescents (50 healthy ones, 40 with excessive weight, and 22 with heredity aggravated by diabetes mellitus). Three types of these changes were distinguished in healthy adolescents: normoreactive, hyperreactive, and inert. The same type of growth hormone secretion changes corresponded to each type of insulin secretion changes. There was revealed a negative correlation between the insulin and growth hormone levels in the group of healthy adolescents. Dynamic relation was noted between the indices of the mentioned hormones in the course of the test: it was stronger during the ascending than during the descending phase of the test. Glucose load proved to change the correlation between the hormones level. In the group of healthy adolescents correlation between the insulin and the growth hormone levels was greater before carbohydrate load than after it. In case of excessive weight or heredity aggravated by diabetes mellitus glucose load disturbed the correlation between the hormones: when a negative correlation existed between the insulin and growth hormone levels before the load no correlation was revealed after in. This fact confirmed the role played by excessive carbohydrate consumption in the pathogenesis of diabetes mellitus.
