Qualitative Behaviour Assessment: quantifying the emotionally expressive qualities of animal behaviour

Qualitative Behaviour Assessment (QBA) is a method that asks human observers to describe and score the emotionally expressive qualities that animals show when they engage with their environment1. Animals can perform any given behaviour (e.g. walking or resting) in different expressive styles, presenting us with a dynamic body language that can, for example, be described as tense and anxious, or relaxed and joyful. Because it includes positive emotions QBA is a valuable method for assessing quality of life. It is, for example, the main indicator for ‘positive emotional state’ in various EU Welfare Quality® assessment protocols2.

Background

Most scientific methods for animal welfare assessment focus on measuring detailed physical aspects of an animal’s health and behaviour, however QBA is designed to assess the dynamic whole animal as it engages with its environment. At this level of integration animals are primarily viewed as sentient, psychologically expressive beings, whose quality of movement reflects their quality of experience. By describing and quantifying such qualities QBA provides useful information, that, in combination with other health and welfare measures, can help us to more confidently assess an animal’s state of well-being3. One of QBA’s strengths is that it captures subtle shifts in demeanour that are difficult to measure otherwise. A transition from a relaxed/content to a more tense/lethargic expression, for example, often indicates the onset of illness4. By contrast a shift towards greater attentiveness and boisterousness in response to environmental enrichment signifies the animals’ enjoyment and a higher level of positive welfare5.

This is an interview with Professor Francoise Wemelsfelder (SRUC) on QBA, made for the open online course in animal behaviour and welfare by The University of Edinburgh. Francoise talks about the ideas underlying QBA, the scientific validation of QBA, and the role QBA can play in practical animal welfare assessment.

QBA can be performed in different ways. A good way to involve stakeholders in a project is to invite them to select 15-20 QBA descriptors particularly suited to that project. Another, faster way is to provide participants with a ready-made ‘fixed list’ of descriptors based on existing scientific literature for a species. QBA term lists should balance positive and negative emotions (valence), and higher and lower energy levels (arousal). Scores based on these terms are analysed using multi-variate statistics, generating dimensional patterns of emotional expressivity. An extensive body of scientific publications shows that with appropriate training, QBA can be performed reliably and make a valuable contribution to scientific animal welfare assessment6.

Project application

There is growing interest in the practical implementation of QBA as a tool for assessing emotional well-being in animals7. For example, the UK retailer Waitrose recently invited SRUC to collaborate in the roll-out of QBA across 12 Waitrose own-brand supply chains (see also Box 1).

Box 1: The QBA mobile application

SRUC (Scotland’s Rural College) is in the process of building a new QBA mobile application for Android and iOS. Development of the app is taking place in collaboration with Waitrose and Partners, and despite being at an early stage has won several awards.

Once publicly available, the app will be usable with any animal species in any context, including farm, laboratory, kenneled, zoo and wild animals. Users can create QBA descriptors that are specifically meaningful to their organisation and culture. The app will analyse scores on these descriptors and show the outcome in an easy-to-read chart for emotional wellbeing that compares an assessment to previous assessments of animals in a project.

The app offers enhanced statistical reliability thanks to the contribution of a built-in algorithm for data normalisation by statistical experts at Biomathematics and Statistics Scotland (BioSS).

QBA Further Resources

This section is a work in progress. It provides a comprehensive collection of published refereed papers and book chapters that either use or discuss QBA. Some papers focus on QBA, others use it as part of larger welfare assessment studies or discuss it as part of wider reviews. To provide some structure, the bibliography is divided into subsections that focus on different animal species or themes like positive welfare or human-animal relationships. Papers can appear in more than one section.
