Obtaining data from multiple informants provides a more comprehensive diagnostic picture in the assessment of attention deficit hyperactivity disorder (ADHD). Differences in symptom ratings have been observed between parent- and teacher-report scales, though less information is available regarding differences between mothers and fathers. To address this gap, this study examines the rater agreement between mothers and fathers on the Diagnostic and Statistical Manual of Mental Disorders – Fourth Edition (DSM-IV) ADHD Symptom Rating Scale (DSM-ADHD-SRS). The participants consisted of 337 children diagnosed with ADHD who underwent comprehensive neuropsychological assessment. Confirmatory factor analysis indicates that a three-factor model comprising inattention, hyperactivity, and impulsivity symptoms provides the best fit for both mothers’ and fathers’ ratings. Mothers provided higher mean ratings for the inattention scale. These results suggest that the factor structure for the DSM-ADHD-SRS is the same, regardless of parent gender. However, symptoms of inattention may vary depending upon which parent completes the ratings. This discrepancy could lead to differences in diagnostic impressions in clinical evaluations. 相似文献

Individual differences in emotion knowledge were examined among 188 4-year-old, predominantly African American children. Cognitive ability and negative emotionality, maternal characteristics (parenting, verbal intelligence, and depressive symptoms), environmental risk, and child sex were examined as predictors of emotion knowledge. Regression analyses indicated that cognitively skilled children who resided in relatively low risk environments with verbally intelligent mothers possessed greater emotion knowledge. Proximal (4-year) child cognitive ability was a stronger predictor than distal (2-year) cognitive ability. Positive parenting at 4 years was correlated with child emotion knowledge, but this relation disappeared when parenting was examined in the context of other predictors. These findings highlight the potential role of child cognitive ability, along with environmental risk and maternal verbal intelligence, in children's emotion knowledge and demonstrate the importance of examining a variety of predictors for their unique contribution to emotion knowledge. 相似文献

The major objectives of this project were to develop and evaluate a brochure to help parents make an informed decision about participation in a fragile X newborn screening study. We used an iterative development process that drew on principles of Informed Decision Making (IDM), stakeholder input, design expertise, and expert evaluation. A simulation study with 118 women examined response to the brochure. An independent review rated the brochure high on informational content, guidance, and values. Mothers took an average of 6.5 min to read it and scored an average of 91.1 % correct on a knowledge test. Most women rated the brochure as high quality and trustworthy. When asked to make a hypothetical decision about study participation, 61.9 % would agree to screening. Structural equation modeling showed that agreement to screening and decisional confidence were associated with perceived quality and trust in the brochure. Minority and white mothers did not differ in perceptions of quality or trust. We demonstrate the application of IDM in developing a study brochure. The brochure was highly rated by experts and consumers, met high standards for IDM, and achieved stated goals in a simulation study. The IDM provides a model for consent in research disclosing complicated genetic information of uncertain value. 相似文献

Bullying involvement is a multidimensional issue and a significant concern for school-aged youth. However, research on bullying involvement within clinical samples is limited. The present study examines the psychometric properties of the University of Illinois Bully, Fighting, and Victimization Scales among children and adolescents presenting for mood symptoms at a behavioral health outpatient clinic. Patients (n = 165) with an age range of 8–18 years were included in this investigation. Item frequencies, internal consistency, and construct validity were examined while confirmatory and exploratory factor analyses were conducted. Results showed that the scales were low to moderately correlated with each other. Internal consistencies were acceptable for the Bully (α = .70), Fighting (α = .84), and Victimization (α = .88) Scales. Exploratory factor analysis revealed clean three-factor solutions with items loading on their intended factors and with few cross-loadings. Fit of the confirmatory factor analysis was good when items were treated as ordinal and two items were allowed to cross-load on more than one factor. The University of Illinois Bully, Fighting, and Victimization Scales show utility for use with clinically referred youth. 相似文献

Students in a general psychology class viewed four videotapes of initial vocational-educational and initial personal concern counseling sessions. The sessions were presented from a client-centered approach and from a behavioral approach, and employed the same client and counselor. After viewing the tapes, the students were asked to indicate which approach they thought would be more effective in helping a client. Results showed that students who had previously experienced counseling preferred a behavioral approach for both the vocational-educational concern and the personal concern. Students with no experience of counseling did not exhibit a preference. 相似文献

An evolutionary perspective predicts that the intensity of the disgust response should depend on the ancestral costs and benefits of coming into contact with disease vectors. Previous research advanced the compensatory behavioral prophylaxis hypothesis: progesterone-induced immunosuppression should be accompanied by increased disgust and contaminant-avoidance. However, extant data do not address whether factors other than progesterone-induced immunosuppression also trigger heightened disgust. The current study delineates two competing prophylaxis hypotheses and adjudicates between them by testing whether stress and satiation, which shift the costs and benefits of prophylactic behavior but are unrelated to progesterone-induced immunosuppression, predict disgust sensitivity. Results revealed a sex–stress–satiation interaction in predicting Disgust Scale-Revised (DS-R) scores. This study provides evidence of a broader system of compensatory prophylaxis, illuminates the functional basis of facultative shifts in disgust, and presents conceptual and statistical analyses for more cleanly cleaving the psychology of disgust at its natural joints. 相似文献

Spiritual Assessment in African-Americans: A Review of Measures of Spirituality Used in Health Research 总被引:1,自引:0,他引:1

Background A number of instruments have been developed for investigating relationships between spirituality and health, and have been
used to assess spirituality in African-Americans. Yet, the cultural appropriateness for African-Americans of these instruments
has not been investigated to date. Objectives To evaluate the construct validity and reliability of spirituality measures used in health research from 1982 to 2005. Method Systematic review of the literature. Results Thirty five studies and five measures of spirituality met the inclusion criteria. Most of the spirituality measures were developed
in primarily Caucasian-American samples. African-Americans were represented in 71% of the studies (n = 25) using spirituality measures in health research. Distinct cultural attributes of African-American spirituality were
omitted in most of the spirituality measures. Two studies were retrieved in which psychometric evaluation was conducted in
entirely African-American samples. Discussion Spirituality is a significant cultural experience and belief that influences the health behaviors of African-Americans. The
lack of a culturally appropriate measure of African-American spirituality is a major limitation of studies investigating spirituality
and health in this population. Development of a culturally appropriate and sensitive measure of spirituality in African-Americans
is suggested to strengthen the quality of research in this area. 相似文献
