The Potential Mediating Role of Parenting Practices in the Development of Conduct Problems in a Clinic-Referred Sample

Research has consistently found associations among parenting practices, socioeconomic disadvantage, ethnicity and conduct problems in children. We investigated whether parenting practices might mediate the relation between ethnicity and conduct problems and the relation between socioeconomic status (SES) and conduct problems. The subjects were 141 clinic-referred children between the ages of 6 and 17 and their primary custodial parents. Using multiple indicators for each construct, except ethnicity, the mediational role of parenting was tested using structural equation modeling. The results indicated that the effects of SES on conduct problems was largely mediated by the influence of ineffective parenting practices. In contrast, ethnicity was not associated with conduct problems in this clinic-referred sample, even prior to controlling for SES and parenting practices, suggesting that the link between minority status and conduct problems may be dependent on the demographic characteristics of the sample. Exploratory analyses also revealed that there were ethnic differences in the types of parenting practices that were most strongly associated with conduct problems.     

The Troublesome Concept of the Person

In today'sbioethical debates, the concept of the person plays a major role. However, it does not hold this role justly. The purpose of this paper is to argue that the concept of the person is unsuited to be a central concept in bioethical debates, because its use is connected with serious problems. First, the concept is superfluous. Secondly, it is a confusing concept and it lacks pragmatic use. Thirdly, its use leads to simplifications. Finally, the concept can easily be used as a cover-up concept. Therefore, it is argued that relinquishing the concept of the person could enhance the clarity and quality of bioethical debate. Moreover, the historic origin of much of the present confusion surrounding the concept of the person is clarified. It is demonstrated that three influences resulting from Locke'sideas on the person and personal identity can be determined as contributing factors to the confusion and controversy within the present bioethical debates centering around the person.     

Are twins different from singletons during early childhood?

This paper examines the specificity of intrafamilial experiences to which twins are exposed during early childhood, and the impact of this family context on the psychological development of twins. An overview of the literature on the psychological development of twins indicates two broad categories of findings. The first category covers studies dealing with the developmental features that appear early in twins. Although there are numerous studies comparing the psychomotor and verbal development of twins to singletons, only a few have dealt with the emergence of personality and identity, and most have been conducted in clinical settings. The second set of studies deals with mother-twin relations, explored in recent years in terms of the psychosocial stress created by twin births. Few studies have examined the mother-twin relationship in the light of major theories on mother-child bonding (psychoanalysis, attachment, interactionist model). These developmental models have mainly focused on mother-infant dyads, while the construction of this specific mother-twin relationship needs to be set within the framework of a triadic situation. Rather than describing a specific ‘twin mentality’, it is argued here that the twin situation should be seen as a special case of adaptative development, both for the mother and the child, which has effects on the formation of the individual.     

FUNCTIONAL ANALYSIS OF A PROGRAM FOR TRAINING HIGH AND LOW PREFERENCE PEERS TO MODIFY DISRUPTIVE CLASSROOM BEHAVIOR1

Although considerable evidence has accumulated regarding the effectivenes of peers as behavior managers, little attention has been directed toward the analysis of components of training programs. Also, it is not known whether high and low preference peers have different reinforcing effects. In this study, a two-phase peer training program was introduced to five high preference and five low preference peer managers. The Managers were assigned one to each of 10 grade-four elementary pupils with high rates of disruptive behavior. Peer Training I was composed of instructions to monitor and reinforce target subject behavior on a time-sample schedule, to record this reinforcement, and to ignore inappropriate behavior in target subjects. Peer Training II introduced, in addition, backup reinforcement for the monitoring behavior of managers. Measures were taken of target subject behavior, antecedent and consequent attention from managers and other peers, monitoring behavior of managers, teacher behavior, and preference ratings of peer managers by target subjects. Significant improvements in target subject behavior occurred following Peer Training I and further improvements occurred following Peer Training II. These changes were paralleled by decreases in the frequency of antecedent and consequent manager attention to problem behaviors, and improvements in the number and accuracy of monitoring checks. Recorded reductions in teacher attention to individual children and to target subjects were not statistically significant. Posttest preference scores improved significantly over pretest scores for low preference managers, while remaining high for high preference managers.     

Family and childhood adjustment in cystic fibrosis

Family adaptation has been commonly associated with the psychological adjustment of chronically ill children. However, few studies have attempted to systematically evaluate this association and its relationship to illness severity. We studied 44 children ages 7 to 15 and their families at a large cystic fibrosis center and obtained measures of 1) impact of illness on the family; 2) family functioning; 3) behavioral adjustment; 4) social competence; 5) ratings of anxiety, depressive, and eating disorder symptoms; and 6) ratings of illness severity and duration. Impact of illness on the family and overall family dysfunction were significantly correlated with illness severity, but not duration. However, impact of illness on the family was significantly correlated with internalizing behavioral symptoms, while family dysfunction was correlated with depressive symptomatology. These findings suggest that illness-related stress is primarily reflected in general emotional and behavioral symptoms, with familial adaptation either ameliorating or exacerbating their development into depressive symptomatology.     

The trials of childhood: The development,reliability, and validity of the daily life stressors scale

The assessment of daily life stress in youngsters is receiving extensive research attention due to its pertinence to psychological and medical problems. This investigation addressed concerns from previous studies of daily life stress in children and adolescents. These included an integration with ratings of negative affectivity, exploration of developmental changes, and presentation of psychometric data. The Daily Life Stressors Scale (DLSS) is a 30-item measure designed to assess the severity of aversive feelings and everday events for youngsters. Three groups of children and adolescents were evaluated to assess the scale's test-retest reliability and construct and concurrent validity. Developmental changes in a normative group were also examined. Results indicated the DLSS to be moderately reliable and valid for children. Also, male children reported more stress than female children, whereas female adolescents reported more stress than male adolescents. Results were discussed with respect to resilience, gender role stress, therapy implications, and usefulness for determining precursors to physiological problems.

Is the association between childhood maltreatment and aggressive behavior mediated by hostile attribution bias in women? A discordant twin and sibling study

Understanding the mechanisms behind aggressive behavior (AGG) is vital so that effective prevention and intervention strategies can be developed. Maltreated children are hypothesized to be prone to social information processing biases, such as hostile attribution bias (HAB), which, in turn, may increase the likelihood of behaving aggressively. The first aim of the present study was to replicate findings regarding associations between childhood maltreatment (CM), HAB, and aggression in a population‐based sample of Finnish female twins and their sisters (N = 2,167). However, these associations might not be causal but instead confounded by familial factors, shared between the variables. The second aim was, thus, to test the associations when potential confounding by familial (genetic or common environmental) effects were controlled for using a multilevel discordant twin and sibling design within (a) 379 pairs of twins (n_pairs = 239) or siblings (n_pairs = 140), and (b) within the 131 monozygotic (MZ) twin pairs. Consistent with previous studies, HAB mediated the association between CM and AGG when familial confounding was uncontrolled. No support was found for the mediation when controlling for familial confounding. Between‐pair associations were found between CM and AGG, and between CM and HAB. In addition, within‐pair associations were found between HAB and AGG, and between CM and AGG, however, these were nonsignificant in the discordant MZ analysis, offering the most stringent control of familial confounding. The results indicate the necessity of taking familial confounding into account when investigating the development of AGG.     

Media exposure and language for toddlers from low-income homes

In the current study, we examined whether the quantity of toddlers’ exposure to media was related to language skills and whether meeting the American Association of Pediatrics (AAP) recommendations of limiting media exposure to one hour or less per day was related to language skills. We examined these associations in a sample of toddlers (N = 157) living in low-income homes. Toddlers were about two years of age (M = 28.44 months, SD = 1.48 months) during the first visit when parents reported on toddlers’ exposure to media in the home. Toddlers were about three years of age (M = 33.61 months, SD = 1.06 months) during the second visit when direct measures of toddlers’ expressive and receptive language and receptive vocabulary skills were completed. Controls were child gender, race, mothers’ education, marital status, work status, and center-based child care. Results indicated that more frequent exposure to media was related to lower expressive language, but not receptive language or receptive vocabulary. The predictor of AAP recommendation was not significantly related to any child language outcomes. These results suggest that media exposure may be related to the displacement of language-enhancing activities during a critical time for toddlers’ language development. However, the AAP media recommendation of one hour may not be related to language development.
