Relationship of sports experience and ego development of adolescent Japanese athletes.

This study examined the relationship of sports experience with ego development. A questionnaire was used to assess experience of Crisis, Exploration, and Commitment in the issues of Athletic Performance and of Being a Teammate in 782 adolescent Japanese athletes (423 boys, M age = 15.2 yr.; 359 girls, M age = 15.0 yr.). Their Ego Levels were assessed using the Washington University Sentence Completion Test. Correlations indicated that scores on Crisis, Exploration, and Commitment in the issues of Athletic Performance and Being a Teammate were generally associated with Ego Development. Multiple regression analyses indicated that, for boys, the issue of Athletic Performance was closely associated with Ego Development, while for girls, the issue of Being a Teammate was closely associated with Ego Development. Sports experience with crisis, exploration, and commitment may be related to accommodation, which is, in turn, related to ego development. The sex differences on issues related to ego development may be associated with differences in sex-role development for boys and girls.

Co-Use of Some Substances Associated With Higher Doses in Adolescents: Findings From the Adolescent Brain Cognitive Development Study.

PURPOSE: Adolescence is a critical developmental period marked by heightened vulnerability to initiating substance use, with long-term implications for health and behavior. Nicotine, alcohol, and cannabis are the most commonly used substances among adolescents. Their use often co-occurs but few studies have described or quantified the patterns and doses of substance co-use in this vulnerable population. METHODS: We used data from six waves of the Adolescent Brain Cognitive Development study. Substance use was measured through a web-based timeline followback interview, and outcomes are operationalized into substance use quantity (in standard units), single use, and co-use (use of two substances on the same day) of alcohol, cannabis, and nicotine. Group differences of average dose in standard units between single use and co-use for each substance class were analyzed using linear mixed-effects modeling in years 4-6. RESULTS: The average dose of nicotine was significantly higher when co-used with alcohol (4.32; 95% confidence interval [CI]: 2.55-6.09; p < .001) or when co-used with cannabis (4.41; 95% CI: 2.76-6.05; p < .001) in year 6; nicotine trends were similar in years four and five. In year 6, the average dose of alcohol was higher when co-used with cannabis (1.87; 95% CI: 0.37-3.36; p = .004) or co-used with nicotine (1.64; 95% CI: 0.06-3.22; p = .03) compared to single use of alcohol. The average dose of cannabis was not significantly different when used singularly or co-used with either alcohol or nicotine in our study years. DISCUSSION: During adolescence, the co-use of substances (namely alcohol and nicotine) may lead to higher average doses compared to single-substance use.

Development of adolescent self-report measures from the National Longitudinal Study of Adolescent Health.

PURPOSE: To present a set of multi-item indicators and associated reliability estimates derived from early research with survey data from adolescents participating in the National Longitudinal Study of Adolescent Health (Add Health). METHODS: Add Health provides information on the health and health-related behaviors of a nationally representative sample of U.S. adolescents, as well as on individual-level and contextual factors that either promote young peoples' health or increase their health risk. Specifically, the 135-page in-home adolescent survey instrument includes multiple items intended to measure individual-level and social-environmental constructs relevant to adolescent health and well-being. This article details the development of a set of multi-item scales and indices from Add Health in-home adolescent survey data. These steps include identification of inconsistent responders, use of a split-halves approach to measurement validation, and use of a deductive approach in the development of scales and item composites. RESULTS: Estimates of internal consistency reliability suggest that many of the multi-item measures have acceptable levels of internal consistency across grade, gender, and race/ethnic groups included in this nationally representative sample of adolescents. In addition, moderate to high bivariate correlations between selected measures provide initial evidence of underlying latent constructs. CONCLUSIONS: This article provides adolescent health researchers with a set of methodologic procedures and measures developed in early research on the Add Health core adolescent data set.

Racial self-categorization in adolescence: multiracial development and social pathways.

Research on multiracial individuals is often cross-sectional, obscuring the fluid nature of multiracial self-categorization across time. Pathways of racial self-identification are developed from a nationally representative sample of adolescents aged 14-18, measured again 5 years later. A significant proportion of multiracial adolescents change racial self-identification across time. Youth who ever report being multiracial are 4 times as likely to switch self-identification as to report consistent multiracial identities. Across this time, more multiracial adolescents either add a racial category (diversify) or subtract one (consolidate) than maintain consistent multiracial self-categorization. Exploratory multinomial analyses show few differences between these pathways on select psychological and social characteristics. Results lend quantitative support to qualitative studies indicating the fluidity of racial self-categorization.

[Sexual development in adolescent girls].

The authors investigated by interviews in Frantiskovy Láznĕ the sexual development and sex life in 614 Czech girls aged 16 to 18 years. It was revealed that the sexual development in 311 girls, where in the course of the year before convalescent treatment in Frantiskovy Láznĕ appendectomy was performed and in 89 probands who were operated twice or more frequently, was highly significantly retarded as compared with 163 probands who had no surgery so far. Comparison of the findings in 426 girls from complete and emotionally balanced families and 140 probands of divorced parents did not reveal a significant difference in their sexual development.

Hospital management of chronic illness in adolescence: a development model.

Attaining adulthood has always been a difficult process in the management and guidance of our adolescent populations. The stress of chronic illness during this developmental stage cna complicate an already overpowering dilemma in adolescents struggling for independence. Too often, health care professionals react to the adolescent patient out of context. In managing their care, it is important to understand the framework of child development theory and also become aware of our own feelings in relating to adolescents. Adolescents have their own concepts of illness and hospitalization that must be assessed in formulating a comprehensive management plan. Taking all of these dynamics into account, hospital staff can present a more educational and preventative approach that involves that adolescent in helping him cope with his development during a vulnerable time.

[Analysis of personality and psychosocial development of adolescent patients in relation to family dysfunction].

The aim of the study was to analyse an individual psychosocial development and personality of adolescents in relation to family dysfunction. 36 patients who committed suicide attempt treated at the Department of Clinical Toxicology Jagiellonian University Medical College in 2004 and 2005 were included. The Adjective Check List (ACL) by H.G. Gough and A.B. Heilbrun was used. The parents of each of the adolescents were interviewed and responded to questions according to special author's designed Questionnaire. Some phenomenon who can influence the personality and may be recognised as a predictors of suicide attempt were found in most of the examined patients. Prophylactic and therapeutic programs for individual patient and his family member should be constructed.

[Adolescent's development and their participation in social projects].

There is an assumption, generally accepted but without enough supporting evidences, about the positive effects of adolescent participation within social projects in their integral development as social actors. The assumption is that their significant involvement in projects will be reflected later in healthy ways of living, in their empowerment and in their citizenship. This article is based on the Doctoral Thesis of the author, and the ulterior book, where she developed methods and tools which provide supporting evidences about the previous assumption concerning the health promotional character of the participative projects on adolescents. Also she has demonstrated that there are positive effects in their families, their organizations and their communities.

Sexual behavior and contraceptive knowledge and use among adolescents in developing countries.

This article offers an overview of sexual behavior and contraceptive knowledge and use among adolescent women across a large number of developing countries. The results demonstrate that almost universally in sub-Saharan Africa and in the majority of countries in other regions, the gap between age at first sexual intercourse and age at first marriage has increased across age cohorts. The predominant pattern is one in which both age at marriage and age at first intercourse have risen, but the increase in age at marriage is greater, resulting in a widening gap. In most countries in sub-Saharan Africa, current contraceptive use is higher among sexually active, unmarried teens than it is among married teens, whereas in Latin America and the Caribbean, current-use levels are higher among married teens. The results also show that adolescents are unlikely to use a contraceptive the first time they have sex and are more likely than older women to experience a contraceptive failure.

[Pregnancy in adolescence--psychosocial development of young mothers and their children].

Hitherto existing concepts on circumstances favouring pregnancies in adolescents have mainly focussed attention on physically precocious maturity, on social risks and on the type of personality of the pregnant adolescents. Based on our material this opinion seems to be in need of correction. Changing of the validity of these factors may be suggested due to psychosocial conditions in connection with both the acceleration of maturity and a new estimation of sexuality including heterosexual development at earlier stages of life. Children from 100 juvenile mothers were clinically and psychologically investigated at the age of 7 years. Neither serious social problems in the children nor considerable deviations of mean average of the physical, mental or social age specific standards could be observed.

The Multimedia Activity Recall for Children and Adolescents (MARCA): development and evaluation.

BACKGROUND: Self-report recall questionnaires are commonly used to measure physical activity, energy expenditure and time use in children and adolescents. However, self-report questionnaires show low to moderate validity, mainly due to inaccuracies in recalling activity in terms of duration and intensity. Aside from recall errors, inaccuracies in estimating energy expenditure from self-report questionnaires are compounded by a lack of data on the energy cost of everyday activities in children and adolescents. This article describes the development of the Multimedia Activity Recall for Children and Adolescents (MARCA), a computer-delivered use-of-time instrument designed to address both the limitations of self-report recall questionnaires in children, and the lack of energy cost data in children. METHODS: The test-retest reliability of the MARCA was assessed using a sample of 32 children (aged 11.8 +/- 0.7 y) who undertook the MARCA twice within 24-h. Criterion validity was assessed by comparing self-reports with accelerometer counts collected on a sample of 66 children (aged 11.6 +/- 0.8 y). Content and construct validity were assessed by establishing whether data collected using the MARCA on 1429 children (aged 11.9 +/- 0.8 y) exhibited relationships and trends in children's physical activity consistent with established findings from a number of previous research studies. RESULTS: Test-retest reliability was high with intra-class coefficients ranging from 0.88 to 0.94. The MARCA demonstrated criterion validity comparable to other self-report instruments with Spearman coefficients ranging from rho = 0.36 to 0.45, and provided evidence of good content and construct validity. CONCLUSION: The MARCA is a valid and reliable self-report questionnaire, capable of a wide variety of flexible use-of-time analyses related to both physical activity and sedentary behaviour, and offers advantages over existing pen-and-paper questionnaires.

Heritability of P300 amplitude development from adolescence to adulthood.

Early adulthood is a period of late brain development corresponding to the age of onset for psychopathology associated with P300 amplitude reductions. Although amplitude from a single occasion is heritable, little is known about genetic influences on change during this period. This is the first study of P300 change to combine latent growth and twin models. P300 at Pz was measured up to three times at approximately ages 17, 20, and 23 in monozygotic and dizygotic male twins using a visual task. P300 decreased with age. Correlations indexing the stability of amplitude over time were high (median r=.72) and almost 90% of the stable variance (i.e., the model intercept) was attributable to genetic influences. The rate of decrease was heritable, and the genes influencing intercept may be the same ones influencing change. Finally, intercept was more heritable than amplitude at any single time point. Intercept may be a more useful aid in the search for genes associated with relevant psychopathology than single measures of P300. Over a broader age range growth indices may be useful "developmental" endophenotypes.

[Pathogenesis of functional retardation of physical and sexual development in adolescents. Status of somatotropic and gonadotropic function].

A study of somatotropic and gonadotropic functions in male adolescents with functional retardation of physical and sexual development has shown an important role of the deficiency of gonadotropins, especially FSH, in the pathogenesis of this condition. LH secretion in retarded physical development (RPD) is lowered to a lesser degree and positively correlates with testosterone deficiency. The feedback in the hypothalamohypophyseogonadal function in RPD is less frequently affected and to a lesser degree than gonadotropic functions. Of the tested methods (tests with TRH, L-DOPA and bromocriptine) STH reserves are better revealed with L-DOPA and TRH tests, gonadotropic reserves, especially LH,--with TRH and bromocriptine tests. The stimulating TRH effect on the growth hormone is indicative of the versatility and nonspecificity of its action on the pituitary gland in functional developmental disorders.

Moral competence and character strengths among adolescents: the development and validation of the Values in Action Inventory of Strengths for Youth.

Moral competence among adolescents can be approached in terms of good character. Character is a multidimensional construct comprised of a family of positive traits manifest in an individual's thoughts, emotions and behaviours. The Values in Action Inventory for Youth (VIA-Youth) is a self-report questionnaire suitable for adolescents that measures 24 widely valued strength of character. Data from several samples bearing on the internal consistency, stability, and validity of the VIA-Youth are described, along with what is known about the prevalence and demographic correlates of the character strengths it measures. Exploratory factor analysis revealed an interpretable four-factor structure of the VIA-Youth subscales: temperance strengths (e.g., prudence, self-regulation), intellectual strengths (e.g., love of learning, curiosity), theological strengths (e.g., hope, religiousness, love), and other-directed (interpersonal) strengths (e.g., kindness, modesty). The uses of the VIA-Youth in research and practise are discussed along with directions for future research.
