Self-informant rating concordance for attention-deficit/hyperactivity disorder (ADHD) symptoms was assessed in 281 adults at the subscale (Inattention, Hyperactivity-Impulsivity) and individual symptom levels. Potential demographic, diagnostic, and informant identity moderators were also investigated. Concordance levels were similar for current and childhood symptoms. Although moderate positive correlations were found between self- and informant ratings on both subscales, informants endorsed more significant inattentive symptom severity. Kappa coefficients were variable, suggesting low concordance for certain symptoms. Sex and ADHD diagnosis moderated concordance, although effect sizes were small. These results have implications for the use of behavior rating scales in diagnosing ADHD, raise questions about the validity of self- and informant ratings, and support the need to investigate individual-differences variables that may impact concordance. 相似文献

Information ambiguity is prevalent in organizations and may influence management decisions. This study examines, given imprecise probabilities or outcomes, how managers decide which department's performance to investigate further when they are provided with performance benchmarks expressed in numerical intervals. Seventy‐nine MBA students participated in two experiments involving investigation decisions. We presented participants with interval benchmarks of a firm's expenses. Being below or above the benchmark should have been seen as equally negative. We found that, when facing outcome ambiguity, our participants consistently preferred to investigate further those departments whose performance was described as having an ambiguous outcome (when the outcome's range was centered either below or above the interval benchmark). However, when facing probabilistic ambiguity, there were two predominant choice patterns: consistently choosing to investigate the department whose performance is described with an ambiguous probability, or consistently choosing to investigate the department with unambiguous performance. To gain further insight, we conducted a follow‐up study collecting written protocols of participants' reasons for making choices involving ambiguous performance information. The results show that our participants displayed similar decision‐making processes when facing outcome ambiguity and probabilistic ambiguity. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

In 1980, Bloom and Fischler published a paper describing a set of sentence contexts (SCs) and their cloze probabilities (CPs).
This material has subsequently been employed in numerous studies of linguistic processing. We sought to define the completion
words and their CPs for Bloom and Fischler’s sentences in an inner-city British population in order to establish reliable
norms for subsequent studies in the U.K. One hundred and fifty incomplete SCs were presented to 73 volunteers. The CPs for
each of the words used to complete the SCs were computed. We then compared the CPs from our sample with those from Bloom and
Fischler. There were significant differences between CPs from each sample in 14% of the SCs analyzed (p < .01). Our data suggest that studies employing SCs and CPs may require locally defined norms if the test population differs
substantially from the original one. The consequences of employing SCs and CPs to study linguistic processing without normalization
are discussed. 相似文献

Overweight people in society face a number of obstacles. Negative attitudes toward overweight people contribute to this experience. This study examined the relationship of antifat attitudes to other prejudicial attitudes (e.g., racism, sexism, homophobia) and gender‐related attitudes. A total of 179 undergraduate participants completed measures of prejudicial attitudes, including antifat attitudes. Multiple regression analyses revealed that a combination of demographic and attitudinal variables predicted antifat attitudes. Antifat attitudes are stronger for men, Caucasians, and gender‐typed individuals; compared to women, African Americans, and androgynous individuals, respectively. After controlling for demographics, weight‐related variables, and social desirability, gender‐role egalitarianism, racism, and homophobia significantly correlated with antifat attitudes. The implications and limitations of this study are discussed regarding the importance of research in antifat and other prejudical attitudes. 相似文献

Measures of adult attachment reflect both respondents' broadly generalized styles as well as bonds with specific attachment figures. Using Cronbach, Gleser, Nanda, and Rajaratnam's (1972) Multivariate Generalizability analyses, the authors estimated the extent to which correlations among attachment, affect, the self, and perceived social support occurred for both styles and bonds. In two studies, participants rated attachment, affect, the self, and perceived support when thinking about their mothers, fathers, and romantic partners. In both studies, attachment dimensions reflected specific bonds much more so than generalized styles. When correlations reflected specific bonds, both anxious and avoidant dimensions were strongly linked to high negative affect, low positive affect, and low perceived support. In contrast, evidence for links between attachment and affect was inconclusive when correlations reflected generalized styles. Links between attachment and the self depended on the type of self-construct and whether styles or bonds were analyzed. 相似文献

A paucity of research has directly compared empirically supported interventions to examine their effectiveness among students with different mathematics fluency skills. The purpose of this study was to compare the effects of two empirically supported interventions and a control condition on the mathematics fluency of 98 second and third grade students. Specifically, effects of explicit timing and cover-copy-compare on subtraction fluency were examined each session, which occurred twice weekly for a total of six weeks. HLM was used to examine progress during the intervention sessions and determine the effect of initial fluency level on intervention effectiveness. Results suggested students' initial level of fluency impacted intervention effectiveness. That is, for students whose fluency levels fell within the frustrational range CCC and control conditions resulted in the best performance over time but for children whose fluency was in the instructional range explicit timing was the most effective treatment. 相似文献

OBJECTIVE: To investigate the attitudes of terminally ill individuals toward the legalization of euthanasia or physician-assisted suicide (PAS) and to identify those who would personally desire such a death. DESIGN: In the Canadian National Palliative Care Survey, semistructured interviews were administered to 379 patients who were receiving palliative care for cancer. Patients who expressed a desire for physician-hastened death were followed prospectively. MAIN OUTCOME MEASURES: Attitudes toward the legalization of euthanasia or PAS were determined, as was the personal interest in receiving a hastened death. Demographic and clinical characteristics were also recorded, including a 22-item structured interview of symptoms and concerns. RESULTS: There were 238 participants (62.8%) who believed that euthanasia and/or PAS should be legalized, and 151 (39.8%) who would consider making a future request for a physician-hastened death. However, only 22 (5.8%) reported that, if legally permissible, they would initiate such a request right away, in their current situations. This desire for hastened death was associated with lower religiosity (p=.010), reduced functional status (p=.024), a diagnosis of major depression (p<.001), and greater distress on 12 of 22 individual symptoms and concerns (p<.025). In follow-up interviews with 17 participants, 2 (11.8%) showed instability in their expressed desire. CONCLUSION: Among patients receiving palliative care for cancer, the desire to receive euthanasia or PAS is associated with religious beliefs; functional status; and physical, social, and psychological symptoms and concerns. Although this desire is sometimes transitory, once firmly established, it can be enduring. 相似文献

Recent landmark content analyses of sexual content on television (e.g., Kunkel, Biely, Eyal, Cope-Farrar, Donnerstein, & Fandrich, 2003) provide a baseline for interpreting depictions of sex on individual programs. The present study was designed to investigate the nature and extent of sexual content on HBO’s popular television series Sex and the City. Compared to television in general, Sex and the City is more likely to depict sexual content (including sexual talk and behavior), intercourse between established partners (rather than between partners who had just met), and sexual risks and responsibilities (including sexual patience, precaution, and risks/negative consequences). Sex and the City does not differ from television in general in terms of pairing alcohol or drugs with sexual intercourse. The results suggest that Sex and the City is more likely than television in general to depict “healthy” sex. 相似文献
