Journal of Intellectual Disability Research

The Journal of Intellectual Disability Research is devoted exclusively to the scientific study of intellectual disability and publishes papers reporting original observations in this field. JIDR also publishes scientific research on autism where the populations studied have an intellectual disability (or autism, where results are reported on participants with both autism and intellectual disability). Submissions are welcomed from any academic discipline contributing to the scientific study of intellectual disability, on research drawing from several disciplines, or on any topic of relevance to the lives of individuals with intellectual disability. Research questions should be of broad relevance to the scientific field of intellectual disability. Studies using well-reported and robust research methods, including qualitative methods, are welcomed. Papers using systematic literature review methods and/or syntheses of quantitative or qualitative data are also welcomed. Conceptual papers are not currently accepted. Clinical case reports and descriptions of interventions or service models/programmes containing no evaluation data are generally not published. Following initial screening, all papers are reviewed by expert referees.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

External Cites per Doc

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
