A review of the dementia research landscape and workforce capacity in the United Kingdom

December 2015

Science-Metrix was mandated by RAND EUROPE to provide a bibliometric analysis of the UK’s dementia research landscape covering the dementias identified as relevant by the client. RAND EUROPE's final report, A Review of the Dementia Research Landscape and Workforce Capacity in the United Kingdom, has now been released.

The data analysis undertaken by Science-Metrix included a range of indicators of research capacity and scientific impact at country and researcher levels. These were designed to help capture information on productivity, performance relative to global benchmarks, specialization, collaboration and multidisciplinarity in the UK system for specific fields and subtopics of dementia.

The indicators included the following:

Country level

  • Number of scientific papers
  • Growth index (GI) last five years compared to the previous five years
  • Specialization index (SI)
  • Average of relative citations (ARC), normalized by field/subtopic and for differences in paper age
  • Average of relative impact factors (ARIF), field normalized
  • Number of highly cited papers (top 10% worldwide), field and subtopic normalized
  • International collaboration
  • Transdisciplinarity index
  • Comparison of UK and the world on the frequency of reference made from dementia to each subfield
  • Positional analysis of leading countries comparing the number of papers, SI and ARC in a single graph

Individual level (top 200 people)

  • Number of scientific papers
  • Growth index (GI), last five years compared to the previous five years
  • Average of relative citations (ARC), normalized by field and subtopic
  • Average of relative impact factors (ARIF), field normalized
  • Number of highly cited papers, field and subtopic normalized
  • Number of collaborations of each researcher with each leading foreign country
  • Within UK collaboration
  • Transdisciplinarity index
  • Targeted analysis of social science experts (50 places reserved for people active in areas of research such as nurses, psychologists, occupational therapists, social workers, physiotherapists and speech and language therapists who are also active in dementia research)

In addition, Science-Metrix complemented this analysis with search techniques to extract the keywords from each paper and produced a visualization map of key topics and themes of UK research activity. The UK was then compared to the world in areas such as relative frequency of keywords and in regard to trends over time. Science-Metrix also conducted an academic age analysis for the top 200 researchers.
