BackgroundMany individuals with autism spectrum disorders (ASD) exhibit social cognitive impairments in the development of theory of mind (ToM), or the ability to attribute mental states to oneself and others. ToM has been shown to relate to reading comprehension for children and adolescents with typical development (TD) and with ASD. This study examined the relation between reading comprehension, word recognition, oral language, and ToM for higher-functioning children and adolescents with ASD (HFASD) as compared to those with TD.Method70 children with HFASD and 40 children with TD, aged 9–17 years, participated in the study. In order to describe the HFASD as compared to the TD sample, a series of ANOVAs and ANCOVAs were conducted. Multiple regression analyses were conducted with reading comprehension as the outcome variable. Separate regression models (TD & HFASD) were run with IQ, word recognition, oral language, and two ToM measures (Happé’s Strange Stories and the Silent Films Task) as predictors.ResultsThe TD group performed better than the HFASD group on all standardized and experimental measures. Regression analyses revealed that after controlling for IQ, word recognition, and oral language, both ToM measures predicted unique variance in reading comprehension in the HFASD, but not the TD, sample. Furthermore, the TD and HFASD groups displayed different patterns of significant predictors of reading comprehension.ConclusionsThis study suggests that in addition to oral language and higher-order linguistic comprehension, social cognition is an important factor to consider when designing reading interventions for students with ASD. 相似文献

The effects of three increasingly intensive training methods on therapist use, knowledge, and implementation adherence of contingency management (CM) with substance abusing adolescents were evaluated. Ten public sector substance abuse or mental health provider organizations were randomized to one of three training conditions: workshop and resources (WS +), WS + and computer assisted training (WS +/CAT), or WS +/CAT and supervisory support (WS +/CAT/SS). Across conditions, 161 therapists participated in the training experiences, and measures were obtained at baseline and 2-month intervals for 12 months following workshop participation. Across training conditions, therapists reported increased CM use, knowledge, and implementation adherence through the 12-month follow-up. The findings show that community-based practitioners are amenable to the adoption of evidence-based treatments when provided access to useful resources. Moreover, high quality workshops in combination with resource access can increase knowledge of the evidence-based treatment and might enhance intervention adherence to a level needed to improve youth outcomes. 相似文献

ABSTRACTTheory of mind describes the ability to engage in perspective-taking, infer mental states, and predict intentions, behavior, and actions in others. Theory of mind performance is associated with foundational cognitive and socioemotional skills, including verbal ability (receptive and expressive vocabulary), executive function (inhibitory control and working memory), and emotion knowledge. In a sample of 354 children from low-income households, theory of mind and foundational skills were directly assessed before and after kindergarten. Results indicate emotion knowledge, inhibitory control, and expressive language predicted improvement in theory of mind. Expressive language also served as a moderator such that children with low expressive language failed to improve in theory of mind regardless of initial theory of mind performance. 相似文献

This paper diagrams and discusses orthogonal cultural identification theory, proposing that cultural identification is developed and maintained through complex interactions and negotiations between the culture and the person. When the individual meets cultural requirements, the culture provides rewards that match cultural needs and reinforce cultural identification. Strong identification with one culture does not prevent identification with another. A breakdown in this interaction can lead to alienation and possibly to identification with a deviant subculture and/or to drug use. 相似文献

Behavioral intention to prevent cervical cancer and related factors among female high school students in Japan 下载免费PDF全文
Aim
This study aimed to examine female high school students’ behavioral intention to prevent cervical cancer and related factors.Methods
The participants were 2158 female high school students at 16 high schools in A prefecture in the Tohoku region in Japan. A self‐administered questionnaire was carried out that was developed based on a conceptual framework comprising the Health Belief Model and Theory of Reasoned Action.Results
The responses were obtained from 2072 students (96.0%). Of these, the answers of 2028 respondents were analyzed after excluding those participants who did not complete the behavioral intention item (effective response rate: 97.0%). A factor analysis and covariance structure analysis yielded a model with strong goodness‐of‐fit that explained the behavioral intentions based on an “Awareness of the importance and effectiveness of cervical cancer screening,” “Obstacles to cervical cancer prevention behavior,” “Subjective norms for adopting cervical cancer prevention behavior,” and “The behavior of someone close that encourages cervical cancer prevention behavior.”Conclusion
The statistical analysis yielded a model with strong goodness‐of‐fit that explained female high school students’ behavioral intentions, which were related to four factors, including “the awareness of the importance and effectiveness of cervical cancer screening.”67.

Background
Real time 1:1 videoconferencing (VC) has the potential to play an important role in the management of orthopaedic pathologies. Despite positive reporting of telemedicine studies uptake in clinical practice remains low. Acceptability to patients is an important element of system take-up in telemedicine and a focus towards qualitative methodology may explore the underlying reasons behind its acceptability. In this paper we have systematically reviewed qualitative studies that include evidence about patient responses to VC services in an orthopaedic setting.Objectives
To determine whether real time 1:1 videoconferencing is acceptable to patients in an orthopaedic setting.Data sources
MEDLINE, AMED, PsychINFO, CINAHL, SCOPUS, Cochrane Database, Evidence Search and Open Grey were searched with forwards and backwards reference screening of eligible papers.Eligibility criteria
Qualitative studies exploring the acceptability of VC in an orthopaedic setting were included.Study appraisal and synthesis methods
Studies were appraised using the CASP tool. A Directed Content Framework Analysis was conducted using Normalisation Process Theory.Results
Four studies were included for review. The themes for the four studies did not overlap and did not report clinician acceptability of VC. The Directed Content Analysis of these papers using Normalisation Process Theory highlighted factors which contribute towards its acceptability.Conclusions
All studies concluded that the use of VC was acceptable. Further qualitative research exploring both patient and clinician acceptability is required utilising a theoretical framework to allow for repeatability and generalisability.Systematic Review Registration Number: PROSPERO CRD42015024944. 相似文献
