In this article, we report on the findings of a qualitative inquiry into how an online message board for people who have Complex Regional Pain Syndrome (CRPS) was used by its members. All messages (and responses) posted on the CRPS message board over a 4-month period were collected retrospectively. The data were analysed using the method of Interpretative Phenomenological Analysis. Members used the message board to seek (and provide) support to those with CRPS, and also to express their emotions, feelings and experiences linked to their condition. The message board provided an important source of support for a patient group that can otherwise become isolated as a result of their mobility problems. Furthermore, the analysis revealed the unrealistic hopes that patients can hold concerning the anticipated outcomes of their treatment. This is an important issue for healthcare professionals to explicitly address when interacting with the patient group. 相似文献

Strong associations between conduct disorder (CD), antisocial personality disorder (ASPD) and substance use disorders (SUD) seem to reflect a general vulnerability to externalizing behaviors. Recent studies have characterized this vulnerability on a continuous scale, rather than as distinct categories, suggesting that the revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) take into account the underlying continuum of externalizing behaviors. However, most of this research has not included measures of disorders that appear in childhood [e.g., attention-deficit/hyperactivity disorder (ADHD) or oppositional defiant disorder (ODD)], nor has it considered the full range of possibilities for the latent structure of externalizing behaviors, particularly factor mixture models, which allow for a latent factor to have both continuous and categorical dimensions. Finally, the majority of prior studies have not tested multidimensional models. Using lifetime diagnoses of externalizing disorders from participants in the Fast Track Project (n?=?715), we analyzed a series of latent variable models ranging from fully continuous factor models to fully categorical mixture models. Continuous models provided the best fit to the observed data and also suggested that a two-factor model of externalizing behavior, defined as (1) ODD+ADHD+CD and (2) SUD with adult antisocial behavior sharing common variance with both factors, was necessary to explain the covariation in externalizing disorders. The two-factor model of externalizing behavior was then replicated using a nationally representative sample drawn from the National Comorbidity Survey-Replication data (n?=?5,692). These results have important implications for the conceptualization of externalizing disorders in DSM-5. 相似文献

Including a family session in a child assessment can significantly advance the assessor's and parents' understanding of the child's problems and enhance the likelihood that parents will follow through on recommendations after the assessment. A family session allows the assessor to observe the child in the family context, test systemic hypotheses, better understand the meaning of individual test results, and try out possible interventions. A family session may also help parents see systemic aspects of their child's problems, help the child feel less blamed, foster positive experiences among family members, and offer the family a glimpse of family therapy. We describe methods and techniques for structuring family sessions and offer guidance on preparing for and conducting such sessions depending on one's case conceptualization. Detailed case examples illustrate each technique and demonstrate the immediate and subsequent impact of family sessions as well as their therapeutic value. We also address common clinical and pragmatic issues. 相似文献

The problem of how word meaning is processed in the brain has been a topic of intense investigation in cognitive neuroscience. While considerable correlational evidence exists for the involvement of sensory-motor systems in conceptual processing, it is still unclear whether they play a causal role. We investigated this issue by comparing the performance of patients with Parkinson’s disease (PD) with that of age-matched controls when processing action and abstract verbs. To examine the effects of task demands, we used tasks in which semantic demands were either implicit (lexical decision and priming) or explicit (semantic similarity judgment). In both tasks, PD patients’ performance was selectively impaired for action verbs (relative to controls), indicating that the motor system plays a more central role in the processing of action verbs than in the processing of abstract verbs. These results argue for a causal role of sensory-motor systems in semantic processing. 相似文献

Want information? How mood and performance perceptions alter the perceived value of information and influence information-seeking behaviors 总被引:1,自引:0,他引:1
Currently, it is not well understood when positive and negative moods would encourage and discourage the process of identifying and seeking out valuable information. Building upon the mood-as-a-resource hypothesis and the mood-behavior-model, this project reconciles mixed findings by investigating and finding support for the hypothesis that positive moods encourage seeking instrumental information when performance is perceived to be weak; whereas negative moods encourage it when performance is perceived to be strong. These effects are due to mood influencing the perceived value (i.e. instrumentality) of information and cannot be explained by arguing that mood altered the affective costs/benefits associated with the information. Overall, these results indicate that positive moods may help individuals acquire information to resolve an existing problem, whereas negative moods may help individuals acquire information when there is no apparent problem. 相似文献

Despite the need for braille literacy, there has been little attempt to systematically evaluate braille-instruction programs. The current study evaluated an instructive procedure for teaching early braille-reading skills with 4 school-aged children with degenerative visual impairments. Following a series of pretests, braille instruction involved providing a sample braille letter and teaching the selection of the corresponding printed letter from a comparison array. Concomitant with increases in the accuracy of this skill, we assessed and captured the formation of equivalence classes through tests of symmetry and transitivity among the printed letters, the corresponding braille letters, and their spoken names. 相似文献

The Halstead-Reitan Neuropsychological Test Battery offers a multifaceted, empirically supported interpretive framework for neuropsychological assessment founded upon raw scores referenced to a brain-damaged sample. Complementary approaches have used T scores from normal samples often composed of community volunteers or medical patients, augmented by regression. By pooling normal controls of all types from published studies, a sample large enough for stratification of core Halstead-Reitan measures by age and education was obtained (206 studies, N1 = 17,980). Comparisons based on T scores with two published normative systems in an outpatient sample produced a continuum: liberal norms for medical patients, intermediate pooled values from many types of subjects, and stringent norms for community volunteers. Features recommending clinical application of pooled norms include enhanced accuracy in clinical situations precluding a full battery, few empty cells or inversions for nonelderly subjects, and a screening application based upon a very large Trail Making Test sample (Trails B: n > 14,000). 相似文献

This study examined cross-sectional and longitudinal patterns of community violence exposure and malleable predictors of these exposure patterns among a community sample of 543 urban African American early adolescents (45.3% female; mean age: 11.76). In each of grades 6, 7, and 8, latent class analyses revealed two patterns of community violence exposure: high exposure and low exposure. For the majority of participants, experiences with community violence were similar at each grade. Impulsive behavior and depressive symptoms distinguished adolescents in the high and low exposure classes in grade 6. Implications for interventions to prevent community violence exposure are discussed. 相似文献

This study examined the hypothesis that maternal socialization of coping would make a differential contribution to youth depression
and externalizing psychopathology depending on youths’ level of exposure to life stress. A sample of 155 youth (M age = 12.41, SD = 1.21) and their maternal caregivers completed semi-structured interviews and questionnaires in a two-wave longitudinal
study over a 1-year period. Results provided evidence for two types of socialization × stress interactions—an amplification-effects
model and a differential-effects model. In the context of interpersonal stress, findings supported an amplification-effects
model wherein the risk and protective effects of engagement and disengagement socialization of coping emerged in youth exposed
to high but not mild levels of stress. In the context of noninterpersonal stress, findings supported a differential-effects
model wherein disengagement socialization of coping contributed to heightened risk among youth exposed to high stress but
dampened risk among youth exposed to mild stress. This research identifies maternal socialization of coping as a noteworthy
contributor to risk for youth psychopathology, and highlights the need to consider parenting × environment interactions when
investigating parenting processes related to youth psychopathology. 相似文献
