Exploratory structural equation modeling (ESEM) solutions have been proposed to represent the factor structures of attention-deficit/hyperactivity disorder (ADHD) in recent literature, yet no studies have assessed those structures in Chinese children. The primary aim of this study was to comprehensively examine the factor structures of the Chinese version of the ADHD Rating Scale-IV (ADHD RS-IV): Home Version. Data on 458 Chinese children aged 3–8 years (boys: 246; 54%) were used to test and compare eleven factor models: confirmatory factor analysis (CFA) models (one-factor, two-factor and three-factor), second-order CFA model, bifactor CFA models (two and three specific factors), ESEM models (two-factor and three-factor), second-order ESEM model, and bifactor ESEM models (two and three specific factors). The results showed that, overall, ESEM models displayed better fit than CFA models. Specifically, the second-order ESEM model with three first-order factors best represented of the ADHD factor structure in our sample. In addition, measurement invariance testing results showed that scalar invariance was established across gender, age and informant groups. Implications for future research are discussed.
This study investigated associations between natural mentoring relationships and academic performance via psychological distress among underrepresented college students attending an elite predominantly White institution (PWI). Specifically, this study explored whether the quantity of natural mentors possessed upon college entry, the retention of natural mentors across the first year of college, and overall changes in the number of natural mentors possessed during the first year of college predicted improvements in students' semester grade point averages (GPAs) via reductions in psychological distress. Participants in this study included 336 first‐year undergraduate students attending a selective PWI. Students were eligible to participate in this study if they were first‐generation college students, students from economically disadvantaged backgrounds, or students from underrepresented racial/ethnic minority groups. Results of this study indicated that a greater number of retained natural mentoring relationships across the first year of college were associated with improvements in students' GPAs via reductions in symptoms of depression from the Fall to Spring semester. The results of this study suggest that institutional efforts to support the maintenance of preexisting mentoring relationships may be an effective approach to promoting the academic success of underrepresented college students during the first year of college. 相似文献

The latencies of the P1, N1, P2, and N2 components of the somatosensory potentials evoked by stimulation of the right and left posterior tibial nerves in the right-, left-, and mixed-handed men and women were subjected to a statistical analysis. The mean latencies of the primary and secondary cortical responses are symmetrically distributed between the right and left sides for all the subjects. The mean latencies obtained of women were significantly shorter than those of men. This difference was accounted for by the fact that the mean body height of women was significantly less than that of men, since there was a significant positive correlation between body height and latency. It was concluded that the conduction times for the cortical input as well as the early cortical information processing, despite synaptic interventions, cannot play a role in the cerebral lateralization concerning the perceptual and manipulospatial tasks. 相似文献
Childhood cancer patients have a greater likelihood of long-term survival than ever before. This study examined both the perceived family functioning of adolescents who had successfully completed treatment for pediatric cancer and the relationship between family functioning and post-treatment adjustment. Eighty-eight adolescent survivors of hematologic malignancies were assessed regarding their family functioning, mental health, self-esteem, global competence, and problem behaviors. Contrary to expectations about the influence of cancer on these families, adolescent cancer survivors reported lower levels of family cohesion than the normative sample of healthy adolescents and their families. While current age, gender, age at diagnosis, and time since treatment completion were generally not associated with adolescents' adjustment, perceived family cohesion and adaptability were strongly related to post-treatment psychological adjustment. 相似文献
Experimentally tested the hypotheses that (1) battered women are in need of numerous community resources upon exit from a domestic violence shelter, (2) working with advocates increases women's effectiveness in obtaining needed resources and social support, and (3) success in obtaining resources and social support increases women's levels of life satisfaction and decreases their risk of further abuse. The initial findings of a short-term intervention project designed to provide postshelter advocacy services to women with abusive partners are presented. One-hundred forty-one battered women were interviewed immediately upon their exit from a domestic violence shelter as well as 10 weeks thereafter. Half the sample was randomly assigned to receive the services of trained advocates who assisted them in accessing needed community resources. Women who worked with advocates reported being more effective in accessing resources and had higher levels of social support and overall quality of life postintervention. Although all women reported some decrease in postshelter abuse, there were no differences between those with and those without advocates, and abuse continued to be a problem for many women. 相似文献
The present study evaluated the efficacy of cognitive-behavioural skills training, patterned after stress-inoculation training, as a preventive intervention for the attenuation of acute clinical pain during a noxious X-ray procedure—the knee arthrogram. Thirty-six adult male outpatients were randomly assigned to one of three groups: Skills Training. Attention-Placebo, and No-Treatment Control. An experimental pain test was administered before and after the interventions, as a generalization measure. Arthrogram pain was assessed by three dependent measures: patient's ratings, radiologist's ratings and videotape ratings completed by two‘blind’ raters. The results failed to support the efficacy of skills training for the attenuation of acute clinical pain, or its generalization to the experimental pain test. Although Skills Training subjects reported using significantly more coping strategies during the arthrogram. many subjects in the two control groups also reported using their own spontaneous strategies. Equivocal data were obtained on the role of ‘self-efficacy’ expectancies in mediating pain behaviour and experience. Experimental pain threshold but not pain tolerance was significantly related to acute clinical pain experienced during the arthrogram. 相似文献
We report an experimental investigation of the effects on comprehension of increasing the decoding speed of three adult learners of English as a Second Language (ESL). Participants were taught to read lists of 25 difficult words in isolation until they could read the entire list at a mean rate of not more than 1.5 secs per word. They were then asked to read passages containing these words. Decoding speed and accuracy measures, for both the word lists and passages, and passage comprehension measures, were obtained. In a temporally contiguous within-subjects repeated trials reversal design, decoding training on isolated words was shown to be associated with significant increases in decoding speed and accuracy both in isolation and context, and improvements in the participants' comprehension. With all participants rate and accuracy gains in context were maintained in the final reversal phase, though the comprehension score gains did not. These results are discussed in terms of their implications for a decoding sufficiency hypothesis. 相似文献
