Serves as an introduction to a special section of the journal on laboratory and performance-based measures of childhood disorders. The articles in the special section were part of the work of a task force established by Division 12 of the American Psychological Association on "Upgrading the Science and Technology of Assessment and Diagnosis." In this introduction, I raise a number of issues involved in the use of laboratory and performance-based measures for the assessment of childhood psychopathology that cut across the different disorders covered in the special section. Some of these issues are common to most techniques used in the assessment of childhood psychopathology; others are more specific to this particular method of assessment. However, by focusing on these issues related to the use of laboratory and performance-based measures, it will hopefully encourage a critical examination of all techniques currently being used in the assessment of psychopathology and highlight important issues involved in translating measures that were developed primarily for use in research into forms that are useful in clinical practice.  相似文献

Dropout from psychotherapy is frequent and limits the benefits patients can receive from treatment. The study of factors associated with dropout has the potential to yield strategies to reduce it. This study analyzed data from a large sample of adults (N = 1,092) receiving naturalistic cognitive behavioral therapy (CBT) to test the hypotheses that dropouts, as compared to completers, had (1) higher symptom severity at treatment termination, (2) a slower rate of symptom change during treatment, and (3) a higher odds that the therapist rated treatment as ending for reasons related to poor outcome. Results showed that although dropouts ended treatment with higher symptom severity than completers, dropouts and completers did not differ in their rate of symptom change during treatment, suggesting that dropouts had higher symptom severity at termination because they received fewer sessions of treatment, not because their symptoms changed at a slower rate. Dropout was also associated with a higher odds of having a therapist-rated termination reason indicating a poor outcome, suggesting that dropout is more likely if patients are dissatisfied with some aspect of the therapy outcome or process. These findings suggest that strategies for monitoring and enhancing patient satisfaction with the process and outcome of treatment may help patients stay in treatment longer and end treatment with fewer symptoms than if they had dropped out.  相似文献

A stop consonant-vowel dichotic listening task was administered to 90 right- handed boys, 30 in each age group of 5, 7, and 9 yr. Half in each group were stutterers, half nonstutterers. Two and a half times as many stutterers as nonstutterers were found to display either a left-ear advantage (LEA) or no ear advantage (NEA). This finding suggested a greater tendency on the part of stutterers, as opposed to nonstutterers, for reversed or bilateral representation of the auditory speech areas of the brain. In addition, both stutterers and nonstutterers displayed significant developmental increases in the number of times they were able to identify both dichotic speech stimuli, thereby supporting the hypothesis of an age-related increase in children's total information processing capacity. The results are discussed in terms of the differences between stutterers and nonstutterers with respect to the issues of motor representation, cognitive modes, and higher-order linguistic processes.  相似文献

The current study examined the potential mediating role of sensation seeking in the well-established negative relationship between age and financial risk-taking. A total of 299 participants, aged 17–90 years, allocated hypothetical money into mutual funds that varied in risk and completed a sensation seeking measure. Hierarchical multiple regressions revealed that the amount of variability age accounted for in risk-taking (4.1%; β = −.22) was significantly reduced when sensation seeking was controlled for (0.8%; β = −.12). A Sobel test revealed that sensation seeking fully mediated the aforementioned relationship. Results suggest sensation seeking’s role as a mediator in more physiologically arousing risk-taking contexts (e.g., surfing). Discussion recommends investigating potential biologically and cognitively-rooted mediators and moderators of the age and risk-taking relationship.  相似文献

The current study investigated the relation of callous-unemotional (CU) traits to bullying, victimization, and proactive and reactive aggression. We also examined whether CU traits will be more strongly related to groups of children exhibiting combined or pure forms of proactive and reactive aggression and combined or pure forms of bullying and victimization. The findings suggested that the presence of CU traits, which consists of three dimensions of behavior, uncaring, callousness, and unemotional, may designate important subgroups of aggressive children. Evidence suggested that the adolescents characterized by higher levels of CU traits were more likely to exhibit combined proactive and reactive aggression in comparison to pure forms of proactive or reactive aggression. Additionally, bullies scored higher on the uncaring dimension, and bully-victims (adolescents exhibiting both bullying and victimization) scored higher on the callous dimension. In contrast, victims of bullying scored lower on the uncaring dimension of behavior.  相似文献

We investigated the associations between same-gender friendship, gender reference group identity, and substance use in college students (54 % male, M age?=?19.23, SD?=?1.23) from the northeastern United States using an online survey. Male students reported greater weekly marijuana, but not alcohol use than female students. Regression analyses revealed that having a greater proportion of same-gender friendships was associated with greater weekly alcohol use for male students and lesser weekly alcohol and marijuana use for female students. Gender reference group identity was negatively associated with weekly marijuana use for male and female students. For female students, gender reference group identity mediated the association between proportion of same-gender friendships and weekly marijuana use. Our study highlights the importance of considering the social context (e.g., the gender of friends) and individual variables relating to gender (e.g. gender reference group identity) in substance use research. Our findings fit within social constructionist models of social development that suggest participation in gendered contexts (e.g., same-gender or other-gender-peer contexts) over time cue gender-typed behaviors such as using marijuana.  相似文献

The present study examined the process of shared leadership in 45 ad hoc decision-making teams. Each team member's leadership behavior (n = 180) was assessed by behaviorally coding videotapes of the teams' discussions. The within-team patterns of leadership behavior were examined using cluster analysis. Results indicated that the likelihood of a team experiencing a full range of leadership behavior increased to the extent that multiple team members shared leadership, and that teams with shared leadership experienced less conflict, greater consensus, and higher intragroup trust and cohesion than teams without shared leadership. This study supports previous findings that shared leadership contributes to overall team functioning, and begins to delineate the extent to which team members may naturally share leadership.  相似文献
