Parent Infant Interaction Observation Scale (PIIOS)

Training the Trainers

Following the training and on successfully attaining the standard required for reliability, participants will then be eligible to deliver PIIOS via the standard training course to professionals in a variety of locations. The practicalities of how this is to be done will be discussed and agreed during the third day.

The PIIOS ‘Training the Trainers’ course has been developed with the emphasis not only of familiarising the participants with PIIOS but also by offering access to Dr Svanberg's teaching material so that once the course is successfully concluded you will be able to join the WIFWU's roster of peripatetic teachers offering the course to front-line practitioners.

Please note, should you be unable to meet the required standards you will not be able to teach the PIIOS. There will not be any second 'training the trainers' course.


The PIIOS is a validated, easy to use tool, designed with the front line practitioner in mind to assess parent-infant interaction between 2-7 months. The PIIOS has been developed to meet the need for a short, easily accessible screening tool to assess parental attunement for professionals such as health visitors, midwives, nursery nurses, social workers and psychologists.

The PIIOS was developed by Dr P.O. Svanberg in collaboration with colleagues at Warwick Infant Family Wellbeing Unit (WIFWU) and has been shown to be reliable and also "teachable", with significantly improved ability to recognize "risky" interaction following a two day training. We are very pleased to announce that Dr Svanberg will be leading this course.

Having retired, Dr Svanberg is essentially 'handing over the baton' and has entrusted the WIFWU to ensure that the PIIOS will survive and continue to be offered with monitored quality.
