Smoking and moods in adolescents with depressive and aggressive dispositions: evidence from surveys and electronic diaries.

Surveys and electronic diaries were used to examine depressive and extemalizing dispositions as they relate to smoking and moods in 170 early adolescents. Negative moods were prevalent, with anger and anxiety reported on 26%-60% and sadness on 16%-40% of occasions. The risk of smoking, urges to smoke, and alcohol intake were elevated in teens with aggressive and depressive dispositions, as were diary reports of feeling hassled, angry, and sad. Girls high in depression and aggression also reported more anxiety, stress, and fatigue and less happiness and well-being than did their peers. For boys, depression seemed to dampen the elevated smoking risks associated with externalizing behaviors. Discussion focuses on gender differences in personality-smoking linkages, adolescent negative affectivity, the unique contributions of survey and diary methods, and the promise of targeted preventive interventions such as affect regulation training.

Expressed emotion, parenting stress, and adjustment in mothers of young children with behavior problems.

Expressed Emotion (EE), a measure of the emotional climate of the family, predicts subsequent adjustment of adults with mental disorder (Leff & Vaughn, 1985). Despite the acknowledged importance of the family in childhood disorders, there have been relatively few studies of expressed emotion with adolescents and school-aged children and virtually none focused on preschoolers. The present study utilized the Five Minute Speech Sample (FMSS) to examine how Expressed Emotion relates concurrently and longitudinally to child problem status in a community sample of 112 preschool-aged children. At preschool, the proportion of high EE increased significantly across three child groups: Comparison (8.1%), Borderline Problem (15.8%), and High Problem (41.2%); however, preschool EE was not predictive of subsequent child status at 1st grade. Expanded FMSS codes. tapping positive affect and worry about the child, were also related to child problem group at preschool and were predictive of subsequent child status at 1st grade. Because parents' stress and adjustment were also highly related to child problem group status, we examined whether the FMSS codes were essentially a proxy for these or whether they explained unique variance. In two stepwise regressions on preschool child group status (divided by total problems and by externalizing problems), maternal stress was the only variable to enter. Also, in predicting to 1st grade externalizing child group status, only maternal stress entered. Discussion focused on the extension of the EE construct and other FMSS coding to young children, and the need to recognize that to some extent these variables may reflect maternal stress and adjustment.

The role of ethnicity and parental bonding in the eating and weight concerns of Asian-American and Caucasian college women.

OBJECTIVES: The purpose of this research was to explore the associations among ethnicity, parental bonding, acculturation, and eating disturbance in Asian-American and Caucasian weight-concerned college women. METHODS: Twenty-five Asian-American and 26 Caucasian weight-concerned women were administered the Eating Disorder Examination interview, the Parental Bonding Instrument, and three subscales of the Eating Disorder Inventory. Asian-American subjects also filled out the Suinn-Lew Asian Self-Identity Acculturation Scale questionnaire. RESULTS: Contrary to hypotheses, weight-concerned Asian-American women reported more dissatisfaction with body shape than did Caucasian women. Moreover, in the Asian-American group, acculturation was not associated with level of eating disturbance. In both groups, perceptions of low maternal caring were associated with higher levels of eating problems. In regression analyses, maternal care emerged as a better predictor of eating disturbance than did ethnicity. DISCUSSION: Results suggest that quality of parent-child relations, particularly the mother-daughter relationship, may be important in the etiology of eating problems, irrespective of ethnicity. Longitudinal investigations will be required to test causal relations.

Fear, anxiety and perceived control in children of agoraphobic parents.

Sixteen children (M = 11 years) of agoraphobic parents were compared with 16 children of parents with no history of psychopathology, matched on age, gender and socioeconomic status. The majority (68%) of children of agoraphobic parents met DSM-III-R diagnostic criteria, anxiety disorders being most common. They reported more fear and anxiety and less control over various risks than did comparison children. Group's perceptions of the prevalence and their vulnerability to these risks did not differ. Agoraphobic mothers reported more separation anxiety than did comparison mothers, and maternal separation anxiety was negatively correlated with children's perceived control. Results are related to models of anxiety transmission.

Worldly and workday worries: contemporary concerns of children and young adolescents.

Top-of-the-head worries were elicited young people, grade 4 to 8, both before and after they completed quantitative risk assessments of specific health and environmental problems. Results revealed that many students carry a substantial worry burden that includes not only personal matters such as grades and social relations, but also concerns about death and about global issues such as homelessness and environmental degradation. The gender and grade differences that emerged were consistent with a developmental extension from self to societal perspectives. Differences in worry profiles from before to after the risk assessment interviews revealed some impact of recent exposure, as illustrated by a pre-post increase from 7% to 30% in students spontaneously expressing AIDS-related concerns. Implications of the breadth and severity of young people's concerns are discussed, as are the ambiguities inherent in standard assessment approaches.

Optimism in children's judgments of health and environmental risks.

Although optimistic bias has been well documented for adults, little is known about how children view their own risks vis-à-vis those of their peers. Two studies of 6th graders examined optimism and the degree of differentiation in perceived risks across diverse health, lifestyle, and environmental problems. The findings revealed perceptions of relative invulnerability and highly differentiated risk assessments. The strongest levels of optimism emerged for controllable and stigmatizing events such as illicit drugs, smoking, and AIDS. The effects of gender, assessment context, and methodological variations were minimal. Discussion focused on the implications for health-promoting interventions with school-age children, the need for developmental information about risk perception processes, and the difficulty of distinguishing realistic from biased optimism.

Preadolescents' perceptions of AIDS before and after Earvin Magic Johnson's announcement.

Compared sixth graders' AIDS concerns before and after Magic Johnson announced that he tested HIV-positive. Examined perceptions of self/other vulnerability (optimistic bias) using questionnaires (Study A) and interviews (Study B). Also examined AIDS worries mentioned in open-ended interviews (Study C). Studies A and B revealed a substantial degree of optimistic bias. Study C showed that AIDS is a prime concern of school-age students, mentioned under free or context-cued conditions by about 50%. There was little detectable effect of the publicity; the sole before--after difference in three studies was one increase in self- and other-vulnerability to AIDS--an increase attributable, with marginal significance, only to girls. Discussed implications for health promotion and differences between assessment approaches.

Perceptions of methylphenidate effects on hyperactive children's peer interactions.

The behavioral constructs that emerge from observers' open-ended impressions of methylphenidate effects on the social behaviors of hyperactive children were examined. Ninety-six undergraduates observed videotapes of two different hyperactive "target" boys, each playing an interaction game with three peers. One target was taking methylphenidate and the other was taking placebo. The valence and content of observers' social perceptions were analyzed. Overall, more negative than positive behaviors were detected, a pattern more pronounced for the placebo than for the medication condition. Interestingly, placebo targets received negative evaluations for poorly controlled behaviors such as noncompliance, aggression, and disruption, but medicated targets received negative evaluations for social inhibition--passive and submissive behaviors. In contrast, the boys' medication state did not consistently influence observers' perceptions of positive social behaviors. Discussion focused on the extent and consequences of medication-related increases in social disengagement and on the ultimate impact of stimulant treatment on hyperactive children's social worlds.

Malleability of social impressions of hyperactive children.

The role of adults' social cognitions in mediating judgments of hyperactive children's medication-related behavior change was explored. Two hundred eight-eight undergraduates observed two videotaped excerpts of a hyperactive "target" boy playing a group game with two peers. Each target was taking either methylphenidate (0.6 mg/kg) during both excerpts, placebo during both excerpts, methylphenidate first followed by placebo, or placebo first followed by methylphenidate. Adults' cumulative social evaluations of the child were assessed after they viewed both video segments. Results indicated that observers combined their perceptions of the two behavior samples into composite impressions using an equal-weight averaging algorithm. Even for children whose behavior improved, adults' ratings of undercontrolled behaviors continued to meet or, in some cases exceed, research cutoff scores used to identify hyperactive children. The findings suggest that the actual behaviors of children with attention-deficit hyperactivity disorder (ADHD) play a more influential role in shaping interpersonal impressions than do perceiver social-cognitive processes such as primacy, recency, or integration biases.

Prosocial behavior in hyperactive boys: effects of stimulant medication and comparison with normal boys.

To clarify the effects of stimulant medication on hyperactive (ADHD) children's prosocial as well as aversive behaviors toward peers, 19 hyperactive boys, aged 7-12, were observed as they acted as "leaders" for groups of 2-4 unfamiliar younger children. In a double-blind crossover design, subjects were observed twice, once on placebo and again on a moderate (0.6 mg/kg) dose of methylphenidate (Ritalin). Thirteen comparison boys, without problems in attention and behavior, were also observed in the same leader roles. Relative to comparison boys, hyperactive boys on placebo were more socially engaged, used more aversive leadership techniques, and were rated as less likable by the younger children in their groups. Aversive social behaviors were the strongest predictors of being disliked by the younger children. No differences were found between comparison and unmedicated hyperactive boys for any aspect of prosocial behavior. Stimulant medication had a general dampening effect on social behavior, significantly reducing social engagement and increasing (mild) dysphoria relative to the placebo condition. The implications of these findings for understanding and treating the peer relationship difficulties of hyperactive children are discussed.

Social impact of stimulant treatment for hyperactive children.

Most children diagnosed with ADHD have extensive and enduring problems in the social arena. Despite its limitations, the standard stimulant treatment regimen for children with ADHD is a useful therapeutic modality as well as an heuristic tool for increasing our understanding of both optimal and problematic interpersonal functioning. This article explores the social impact of stimulant treatment, delineating documented improvements, identifying elusive domains and puzzling patterns, and highlighting unintended and potentially undesirable outcomes. Medication-related changes in the behaviors and perceptions of the diagnosed child's adult caretakers are distinguished from those observed in peers, and the need to enhance our understanding of peer cultures is underscored. We present new findings on the effects of stimulant treatment on social cognition and affect, and then discuss the critical need to map the attributional sequelae of any treatment approach. The final sections explore contemporary controversies and improved strategies for balancing the costs, risks, and benefits of stimulant treatment in the service of enhancing interpersonal competence, satisfaction, and harmony.

Social judgment processes in hyperactive boys: effects of methylphenidate and comparisons with normal peers.

Although there is consensus that ADHD children have serious social problems, there is little understanding of the mechanisms underlying or accompanying such problems. To examine the possibility of atypical or faulty social reasoning, we presented ADHD and normal boys with a social perception task that entailed evaluating the behaviors of unknown peers. ADHD "judges" participated under both methylphenidate and placebo conditions, and on each occasion they evaluated an unfamiliar ADHD "target" in each medication state. In contrast to placebo, methylphenidate appeared to dampen overall response rates in ADHD judges, but there was no effect on sensitivity to medication-related differences. Regardless of their own medication state, ADHD judges identified more undesirable behaviors in peers on placebo than in those taking methylphenidate. Judges with the most serious behavior problems tended to identify the greatest number of negative behaviors in peers, especially when both judge and target were unmedicated. There were no effects of target medication status on detections of positive behaviors and few differences in detection patterns of ADHD versus normal judges. Discussion focused on the need to distinguish general regulatory from specific social-cognitive processes.

Hyperactivity and attention deficits.

Substantive progress has been made in our understanding of children considered hyperactive, especially in the interpersonal sphere. Evolving conceptualizations of hyperactivity and attention deficits are reviewed briefly, including changes in clinical diagnostic practices and in knowledge about developmental course. The hypothesis is advanced that the cognitive and social difficulties of hyperactive children may be better understood in terms of motivational and self-regulatory processes than as deficiencies in basic information processing. The role of stimulant medication is emphasized, both as a controversial treatment approach and as an adjunct to research on the children's problems.

Does stimulant medication improve the peer status of hyperactive children?

Although stimulants improve the social behaviors of hyperactive children, analogous changes in peer status have not been previously demonstrated. We compared peer appraisals of hyperactive boys (N = 25) after placebo, 0.3 mg/kg, and 0.6 mg/kg methylphenidate (Ritalin). With the higher dose generally producing stronger effects, methylphenidate enhanced social standing, increasing nominations of hyperactive boys as best friends, cooperative, and fun to be with. These medication-related improvements, although important, did not normalize peer appraisals, and there was marked interindividual variability in medication response.

Externalizing behavior disorders, situational generality, and the type A behavior pattern.

Measures of the Type A Behavior Pattern (TABP) in children have demonstrated good sensitivity but problematic specificity. Using the most popular measure of childhood TABP, a teacher rating scale called the MYTH, we sought to (a) replicate earlier findings of extensive overlap between TABP and externalizing behavior problems, (b) further distinguish between and extend the empirical networks for the positive (Competition) and negative (Impatience-Aggression) components of TABP, and (c) explore cross-situational generality. Normal boys and those with attention-deficit hyperactivity disorder (ADHD) were assessed on multiple instruments in diverse contexts. ADHD boys obtained higher TABP Total and Impatience-Aggression scores than normal boys, and these scores were associated with a wide array of behavior problems and peer difficulties. In contrast, the Competition subscale was related to popularity and athleticism and, inversely, to internalizing problems. Discussion focused on the construct validity of the MYTH, the heterogeneity of boys identified by the MYTH as showing the TABP, and the need for distinguishing research uses of the measure from applications of the TABP concept.

Peer perceptions of hyperactivity and medication effects.

This study focused on peer sensitivity to differences in social behaviors between hyperactive and normal comparison peers and, especially, to medication-related behavioral differences. In Study 1, normal sixth graders rated videotapes of normal and hyperactive boys playing a social interaction game. Half of the hyperactive boys were taking methylphenidate, and the other half placebo. In Study 2, fourth- and sixth-grade children rated a different sample of hyperactive boys (seen on both methylphenidate and placebo) playing the same interaction game. Hyperactive boys taking placebo were perceived as exhibiting more externalizing problem behaviors than either medicated hyperactive boys or comparison boys. The medication effects were robust, spanning many behavioral domains and emerging consistently across the 2 studies. There were few grade or gender differences. Discussion focused on children's detection of treatment-related differences in the social behaviors of their peers, as well as on the imperfect relation between social behavior and social standing.

Psychostimulant medication and perceived intensity in hyperactive children.

Adult ratings of children's activity, based on impressionistic scales, are good indicators of psychostimulant medication effects. These ratings seldom correlate with objective indicators, however, and their behavioral referents are poorly understood. Two separate studies tested the hypothesis that intensity of child behavior, as perceived by others, would differentiate medicated and unmedicated states. College student subjects assessed randomized videotaped segments of children's behaviors. The perceived intensity of hyperactive children's responses decreased with medication. while there were no medication-related changes in either gross motor locomotion of off-task behaviors. In a test for observer sensitization or expectancy, the results for subjects who were looking for medication effects did not differ from those for uninformed subjects.
