Pain and Distress

Assess for pain and its intensity

With caregiver input and adapted tools, such as the Chronic Pain Scale for Nonverbal Adults with Intellectual Disabilities74, 75 or the Non-Communicating Adult Pain Checklist76, 77, assess for pain and its intensity.

Strongly Recommended

Empirical Expert

Pain and distress can manifest atypically in patients with limited communication and can be difficult to recognize. Nonspecific changes in vital signs, appearance, and behaviour, including being less responsive and more withdrawn or new onset of behaviours that challenge  (see guideline Behaviours that Challenge), might be the only indicators of pain and distress.72, 73

Consider behaviours that challenge

Employ a comprehensive and systematic approach to assessing behaviours that challenge that might be communicating pain or other causes of distress (see guideline Behaviours that Challenge).14, 72, 81, 82

  Strongly Recommended

Empirical Expert

Common sources of pain include injury, dental caries, gastroesophageal reflux disease (GERD), arthritis, constipation, and dysuria.78-80 Distress can be a response to pain, challenges in the person’s environment (eg, sensory hypersensitivity), lack of supports or some negative life experience.72, 73

Chronic pain scale for nonverbal adults with intellectual disabilities (CPS-NAID)

Download the Chronic pain scale for nonverbal adults with intellectual disabilities (CPS-NAID) from the Centre for Pediatric Pain Research. This pain scale was adapted from the Non-communicating Children’s Pain Checklist-Revised to assess chronic pain in people over 18 years who have intellectual and developmental disabilities and are unable to communicate verbally.

Non-communicating adult pain checklist

Download the Non-communicating adult pain checklist from the Pain BC website to help assess chronic pain in non-communicating adults such as those with intellectual and developmental disabilities.

DisDAT v20: Disability distress assessment tool

The DisDAT v20: Disability distress assessment tool was developed by a combined learning disability and palliative care team in the north east of England, UK for identifying distress in people with moderate to severe communication difficulties. The tool is free to download and copy, the only restriction being that it cannot be modified in any way, including by adding organizational logos.
