This review summarizes the literature on the relationship between marital conflict and child maladjustment with an emphasis on variables that qualify, explain the association, or both. Following a historical review, the modest findings on the strength of the association between marital conflict and child maladjustment is explored. The definition of marital conflict is clarified through specification of its various dimensions (frequency, intensity, content, resolution). The role of variables that serve to moderate and/or mediate the relationship between marital conflict and child maladjustment are elaborated. Mediating models include exposure theories (Modeling, Cognitive–Contextual effects: appraisal of threat and blame, and Emotional Insecurity) and changes in the parent–child relationship (Spillover). Variables that moderate or qualify the relationship include children's cognitions and behaviors, contextual factors, and demographic differences. A model is presented summarizing these mechanisms. Research recommendations are proposed and the clinical implications of this literature are addressed.  相似文献

Vision, Visibility, and Empirical Research. In general, natural scientists use the concept of observation in a liberal way: they talk of observing electrons, DNA, or distant quasars. Several philosophers of science have recently argued for a similar use of the concept of observation: they have claimed that the important aspects of scientific research can only be properly reconstructed in accordance with how this term is actually used in science. With reference to an example from astronomy, I point out that the proposed generalisation of the concept of observation leads to undesirable consequences. I argue that a differentiated conceptual framework is required in order to give an adequate account of the varieties of scientific experience. Thus, the appropriate starting point for distinguishing these various scientific research practices should not be the generalised scientific conception of observation, but instead distinctly different uses of the term observation drawn from ordinary language. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

In this paper, the report by the Committee on the Prevention of Reading Difficulties in Young Children is discussed from a practitioner's perspective. The many and notable strengths are described, including the comprehensive review of the topic, the balanced manner of the report's conclusions, and the way in which the report was written. The weaknesses of the report also are presented.  相似文献

Much debate has centered on what are reasonable outcomes of the short-term intensive family preservation services (IFPS). However, little attention has been given to how therapists actually formulate outcomes in their practices. The files of 98 families who used IFPS were reviewed to determine how therapists formulated outcomes and whether formulated outcomes varied by service sector (child welfare or mental health) and child age. It was found that formulated outcomes in mental health were more likely than those in child welfare to have a child focus and an interpersonal locus. Variation in outcome formulation in child welfare by child age was found, with outcomes of younger children more likely to be parent-focused than were outcomes of older children. The issues pointed out by these findings are discussed. Since case records are a potential data source for researchers, the paper concludes with a discussion of the strengths and limitations of case record reviews for research purposes.  相似文献

Children of HIV-infected mothers have more psychosocial adjustment difficulties than do those of noninfected mothers. In this study, child psychosocial adjustment in children of HIV-infected women is examined across the three stages of HIV-infected: asymptomatic, symptomatic and AIDS. Participants were 99 HIV-infected women and 148 noninfected women. Children were not identified as being HIV infected. Mother and child reports of behavioral difficulties are compared, and competing hypotheses about mother report of child behavior difficulties are tested. Results indicate an ascending linear trend for child report of internalizing and externalizing difficulties from the noninfected stage through increasingly severe stages of HIV-infection. According to mother report, child externalizing and internalizing difficulties are nonlinear, as mothers report an increase through the infected symptomatic stage, then a decrease in the AIDS stage. Implications for assessment, prevention and intervention in families with maternal HIV infection are discussed.  相似文献

Sixty-one single Japanese-speaking women between the ages of 18 and 26 years were recorded as they read aloud picture books to a young child and as they conversed with another Japanese-speaking woman. When their utterances were acoustically compared between the two settings with regard to prosodic features, both the average pitch and pitch excursions exhibited a significant increase when interacting with the child in 17 of the 61 women. In 36 of the remaining 44 subjects, neither of these parameters showed such changes. This individual variability was not related to the subjects' liking for picture books, previous experience with reading or being read them, or with baby-sitting. The only variable that could explain the results was whether the subjects had grown up with one or more siblings or as only children. If they were only children, the prosodic modification was significantly less likely to occur  相似文献

We examined the extent to which variations in session duration affected the outcomes of functional analyses. Forty-six individuals, all diagnosed with mental retardation and referred for assessment and treatment of self-injurious or aggressive behavior, participated in functional analyses, consisting of repeated exposure to multiple test conditions during 15-min sessions. For each set of assessment data, new data sets based on session durations of 10 and 5 min were prepared by deleting data from the last 5 and 10 min, respectively, of each session. Each graph (N = 138) was then reviewed individually by graduate students who had previous experience conducting and interpreting functional analyses, but who were blind to both participant identity and session duration. Interpretations of behavioral function based on the 10- and 5-min data sets were then compared with those based on the 15-min data sets. All of the 10-min data sets yielded interpretations identical to those based on 15-min data sets. Interpretations based on the 5-min and 15-min data sets yielded three discrepancies, all of which were the result of increased response rates toward the latter parts of sessions. These results suggest that the efficiency of assessment might be improved with little or no loss in clarity by simply reducing the duration of assessment sessions.  相似文献

We evaluated a methodology for identifying the range of stimulus features of antecedent stimuli associated with aberrant behavior in demand contexts in natural settings. For each participant, an experimental analysis of antecedents (Phase 1) was conducted to confirm the hypothesis that task instructions occasioned increases in aberrant behavior. During Phase 2, specific stimulus features associated with the presentation of task instructions were assessed by evaluating the child's behavior across two distinct settings, therapists, and types of tasks in a sequential fashion. Aberrant behavior occurred immediately across settings and therapists, presumably because the presence of a discriminative stimulus for escape-maintained behavior (the delivery of a task instruction) occasioned aberrant behavior. However, aberrant behavior decreased initially across tasks, suggesting that familiarity with the task might be a variable. During Phase 3, an experimental (functional) analysis of consequences was conducted with 2 participants to verify that aberrant behavior was maintained by negative reinforcement. During Phase 4, a treatment package that interspersed play with task instructions was conducted to disrupt the ongoing occurrence of aberrant behavior. Immediate and durable treatment effects occurred for 2 of the 3 participants.  相似文献

To investigate infants’ affective expressivity and maternal attuned responsiveness to infant expressivity in relation to early language achievement, 77 dyads were visited in their homes at 9 and 13 months, and mothers were interviewed about their children’s language between 9 and 21 months. Maternal responses that were attuned to infant affect, by selectively matching either the gradient features or the valence of infants’ affective expressions, were more predictive of children’s language achievement than maternal nonmatching responses; and maternal matching responses at 9 months were more predictive of children’s language achievements than maternal responses at 13 months. Moreover, maternal matching responses at 9 months predicted second-year language achievements over and above infant affect expressivity at 9 and 13 months, and over and above maternal matching responses at 13 months. Infants’ affective expressivity per se was not predictive.  相似文献
