Welcome to PAS-ADD

Mental health assessment tools for use with people with intellectual disabilities, adolescents, and children.

Choose your assessment

The PAS-ADD tools are designed to work alongside clinical expertise. They map closely to the various roles played by health and social care staff working with people who have intellectual disability and mental health problems.

Overcome communication difficulties

Family members or professional carers can often give first-rate information about the person they care for. PAS-ADD uses informant interview to draw upon and maximise the potential of their insight.

Interpret results with ease

All four of the assessments use transparent threshold scoring systems to help you make a reliable and evidence-based interpretation. The Clinical Interview provides full diagnoses under both ICD 10 and DSM IV (TR).
