World University Rankings 2019 by subject: psychology methodology

The Times Higher Education World University Rankings 2019 psychology subject ranking includes a range of narrower subject areas.

The subjects used to create this ranking are:

• Psychology
• Educational/sport /business/animal psychology
• Clinical psychology

Different weights and measures

The subject tables employ the same range of 13 performance indicators used in the overall World University Rankings 2019, brought together with scores provided under five categories.

However, the overall methodology is carefully recalibrated for each subject, with the weightings changed to suit the individual fields.

The weightings for the psychology ranking are:

• Teaching: the learning environment
  27.5 per cent
• Research: volume, income and reputation
  27.5 per cent
• Citations: research influence
  35 per cent
• International outlook: staff, students and research
  7.5 per cent
• Industry income: innovation
  2.5 per cent

Criteria

There are two criteria to be included in the subject rankings: a publication threshold by discipline and an academic staff * threshold by discipline.

No institution can be included in the overall World University Rankings unless it has published at least 1,000 research papers over the five years that we examine.

For the 11 subject tables, the publication thresholds are set differently.

For psychology, the threshold drops to 150 papers published in this discipline over the past five years.

There is also an academic staff eligibility criterion. Up through the 2018 subject rankings, an institution had to have at least 1 per cent of its academic staff working in the psychology discipline to be included in the subject table.

For the 2019 subject rankings, we have made a small adjustment in the staff eligibility criterion. An institution must have at least a minimum proportion of its staff or at least a minimum specific number of its staff in this discipline to be included in the subject ranking.

For psychology, an institution must have at least 1 per cent of its academic staff or at least 20 academic staff in this discipline.

*Academic staff is defined as the full-time equivalent number of staff employed in an academic post, eg, lecturer, reader, professor.
