Debriefing the family: is research an intervention?

The primary focus of this article is to examine the general assumption that families are left largely unchanged by their participation in research, and to question whether family research can have unintended positive or negative effects on participants. The present article reports feedback from families participating in the Nonshared Environment and Adolescent Development project, a longitudinal study of family process and adolescent development. Families differed in their perceptions about whether the research experience was positive, detrimental, or inconsequential. This feedback underscores the researcher's ethical responsibility to detect and remove deleterious effects of participation. Suggestions are made for providing adequate debriefing to subjects and for using debriefing as a research tool to study the interaction between researcher and families.

Interaction sequences in families of psychiatrically hospitalized and nonpatient adolescents.

A KEY theme running through competing views of family influences upon adolescent development is that of directionality, on two levels: influences within the flow of family interaction; and influences from family processes to individual adolescent development. In this paper our focus is upon the first level, intrafamilial sequences within families. More specifically, we study links between psychiatric impairment in adolescence and developmentally relevant parent-child and parent-parent sequences. This report extends a previous investigation (Hauser et al. 1984), which described our new family coding system and first correlational findings. We now study the flow of interactions within these families. Although there has been much recent empirical research in adolescent psychosocial development (e.g., Redmore and Loevinger 1979; Loevinger 1976; Adams and Fitch 1982; Hauser et al. 1984), one important area has received less attention--the relationship between developmentally relevant family processes and psychiatric disturbance during adolescence.

The development of antisocial behaviour from childhood to adolescence. A longitudinal twin study.

Recent theory proposes that aggressive and nonaggressive antisocial behaviour (ASB) represent different pathways toward delinquency. It has also been suggested that Aggressive ASB is heritable, whereas nonaggressive ASB is more influenced by shared environment. The twin study of child and adolescent development is a Swedish population-based study of 1,480 twin pairs. The present study included 1,226 twin pairs. We used the parental-reported Aggression and Delinquency scales from the CBCL measured at age 8-9. Delinquent behaviour was measured through self-report at age 16-17. We explored how genetic and environmental effects influence the relationships between aspects of ASB in childhood and adolescent delinquency using structural equations modelling. For girls we found that the relationship between Aggressive Behaviour and Self-Reported Delinquency was explained by genetic influences. The correlation between Delinquent Behaviour and Self-Reported Delinquency was due to continuity of genetic influences. For boys, there was no significant mediation between Aggressive Behaviour and Self-Reported Delinquency, but there were significant shared environmental effects on the relationship between Delinquent Behaviour and Self-Reported Delinquency. Our results suggest that there are sex differences in the development of ASB. The hypothesis that the aggressive pathway is genetically mediated was supported in girls, whereas the hypothesis that the nonaggressive pathway is environmentally dependent was supported in boys.

Cognitive deficits in adolescents who developed diabetes early in life.

A comprehensive battery of neuropsychological tests was administered to 125 adolescents with a history of insulin-dependent diabetes, and to 83 demographically similar nondiabetic control subjects. To test the hypothesis that developing this disease early in life greatly increases the risk of manifesting significant cognitive impairments, diabetic subjects were assigned to an "early-onset" (diagnosis before age 5 years) or a "later-onset" subgroup. Results showed that subjects with early onset of diabetes performed more poorly than either subjects with later onset of diabetes or nondiabetic control subjects on virtually all tests, including measures of intelligence, school achievement, visuospatial ability, memory, motor speed, and eye-hand coordination. Moreover, multiple regression analyses demonstrated that the age at onset and the duration of diabetes seem to affect neuropsychological functioning in very different ways. The duration of the disease best predicted performance on those tests requiring highly overlearned, primarily verbal, skills whereas the age at onset best predicted scores on tests requiring the ability to process relatively unfamiliar, typically nonverbal, information in novel ways. Although the etiology of these deficits remains unclear, there is a possibility that they are secondary to mild brain damage that develops as a consequence of multiple episodes of serious hypoglycemia early in life.

Growth and development of adolescent girls from the Segou Region of Mali (West Africa).

In Mali, adolescent girls face many physical stresses which, with a history of poor nutrition, can result in delayed growth and development. Despite the fact that adolescent girls encounter nutritional demands, most research in Mali has focused only on young children. This study examines anthropometric and reproductive data on 1,056 adolescent girls (aged 10-17 years) from the Segou Region of Mali. When compared to the reference population, the Malian girls exhibited poorer indicators of growth and development. Z-scores for height-for-age and weight-for-age were below 0 at all ages. Urban girls had better indicators of growth than rural girls. The body composition data show that the Malian girls have lower body fat than reference girls. Menarche was delayed by about 1.5 years compared to girls from the United States and Europe. Delayed growth and development may be due to many factors, including a history of undernutrition, poor socioeconomic status, and increased energy demands.

The differential development of adolescent alcohol expectancies may predict adult alcoholism.

To investigate changes in adolescent's alcohol expectancies as a function of increasing age and drinking experience, we compared the degree to which 12-14, 15-16, and 17-19 year old adolescents from normal seventh to twelfth grade classrooms (N = 1580) affirmed items comprising seven alcohol-expectancy scales. Results showed that adolescents increasingly believe alcohol improves social behavior, increases arousal, and decreases tension as they age. In contrast, the belief that alcohol improves cognitive and motor functioning increased and then decreased in a general adolescent sample, but remained high in problem drinking adolescents. The subsequent discovery of this same factor in 305 hospitalized alcoholics suggests that strong affirmation of this expectancy in late adolescence may have prognostic, and perhaps etiologic significance for the development of alcoholism.

[Risk-taking behavior and accidents in adolescence in developed countries].

Injuries due to accidents are the primary cause of fatalities among adolescents. Between the ages of 10 and 19, mortality caused by accidents augments significantly, and there is an excess of male mortality, increasing with age. This mortality has remained virtually unchanged over the past 25 years, except for a small narrowing of rate differences by sex. Traffic accidents, particularly those involving motorcycles, are the leading cause of accident fatalities. Though not easily assessed, morbidity due to accidents is probably very high, especially among males. Sports accidents are the most frequent. Adolescents appear to be particularly exposed to some risks, but also tend to be careless about safety. Risk-taking is a source of rewards: pleasure, self-affirmation, sense of independence; but it is described by some authors as self-destructiveness, death from accidents reflecting suicidal tendencies. Paradoxical results of prevention have been observed in this age group.

Adolescent brain development: a period of vulnerabilities and opportunities. Keynote address.

This article introduces and summarizes the goals of the symposium. It also provides an overview of a conceptual framework for understanding adolescence, which emphasizes how the very nature of this developmental transition requires an interdisciplinary approach-one that focuses on brain/behavior/social-context interactions during this important maturational period. More specifically it describes a set of neurobehavioral changes that appear to be linked to pubertal development, which appear to have a significant effect on motivation and emotion, and considers these puberty-specific changes in affect in relation to a much larger set of developmental changes in adolescence. This framework is used to argue for the need for a transdisciplinary dialogue that brings together work in several areas of neuroscience (including animal models) and normal development with clinical and social policy research aimed at early intervention and prevention strategies.

Functional correlates of verbal memory deficits emerging during nicotine withdrawal in abstinent adolescent cannabis users.

BACKGROUND: Cannabis remains the most widely used illicit substance by adolescents and is typically consumed by this population in the context of ongoing tobacco use. Human studies have shown that both cannabis and tobacco exert effects on cognitive function; however, little is known about possible interacting effects of these drugs on brain function and cognition during adolescent development. METHODS: Verbal learning and memory were assessed in 20 adolescent users of tobacco and cannabis and 25 adolescent tobacco users with minimal history of cannabis use. Functional magnetic resonance imaging was used to examine brain function and functional connectivity while a subset of these subjects performed a verbal working memory task. RESULTS: Delayed recall of verbal stimuli deteriorated during nicotine withdrawal among cannabis users but not among comparison subjects. During high verbal working memory load, nicotine withdrawal selectively increased task-related activation of posterior cortical regions and was associated with disruption of frontoparietal connectivity in adolescent cannabis users relative to comparison subjects. CONCLUSIONS: These observations suggest that cannabis use during adolescent development may disrupt neurocircuitry supporting verbal memory formation and that deficits associated with disruption of these neurocircuits are unmasked during nicotine withdrawal.

Measuring the self-care practice of children and adolescents: instrument development.

PURPOSE: To develop an instrument to measure the self-care practice of children and adolescents. SUBJECTS: 471 students, age 9-18, in 4th-12th grade. METHODS: This methodological study involved item development and testing the instrument for reliability, readability, and construct validity. FINDINGS: Study findings for the 35-item Child and Adolescent Self-Care Practice Questionnaire included a coefficient alpha of .83 and moderate correlations with two self-care agency instruments. Factors corresponding to the self-care requisites in Orem's model were identified using a LISREL confirmatory factor analysis approach. CONCLUSIONS & IMPLICATIONS FOR NURSING: The Child and Adolescent Self-Care Practice Questionnaire can be used in further research to determine how children and adolescents perform as self-care agents. Activities are identified and measured, intervention strategies to improve behaviors can be planned.

Family Violence and Development during Adolescence.

Adolescence is a time of major physical, emotional, social, and personal development. This chapter focuses on how these developmental issues are related to the types, causes, outcomes, prevention, and treatment of family violence involving adolescents. As adolescents are not well represented in the family violence literature, the authors conclude the chapter with a section on the need for further research in this area.

Adolescence: a literary passage.

Using Erikson's and Gilligan's theories of adolescent development, this paper presents a content analysis of the depiction of adolescent development in a sample of Newbery Medal winners and honor books. Some diversity was found among the major characters, but white males were overrepresented. Many of the characters underwent an identity crisis. Some passed through the identity versus role confusion stage; others, especially in the almost prototypical male-initiation-rite stories, discovered ways to deal with nature (industry) which engendered a far clearer sense of self (identity). The major female characters experienced the two phases more or less simultaneously, but a similar fusion existed for a number of the male characters. The themes of "separation" and "connection" were paramount in the stories, and what Gilligan has called "the ethic of care" was presented positively. Some main characters matured only when they recognized their responsibility to others.

The effect of attitude on the development of adolescent cigarette use.

The purpose of this study is to examine the relation of attitude toward smoking among never smokers to the growth or development of cigarette use during the adolescent years. Using Latent Growth Modeling, attitude toward smoking of 250 adolescents (48% male, 94% Caucasian), 11 to 15 years of age, who had not previously tried a cigarette, was related to the frequency of use at the next assessment, one year later, and growth in cigarette use across four subsequent years. The results indicated that attitude toward cigarettes significantly predicted both frequency of subsequent cigarette use and growth in use. These results suggest a need to focus prevention efforts on attitude change at an early age, prior to experimentation with cigarette use.
