Background: People with learning disabilities experience bereavement in the same emotionally overwhelming way as the general population. The Dual-Process Model of grief is characterised by the oscillation between "Loss-Orientation" and "Restoration-Orientation." These processes involve experiencing and accepting the emotional pain of grief ("Loss-Orientation") and adapting to a new world without the deceased person ("Restoration-Orientation"). Methods: A single case study sought to explore how Cognitive Behavioural Therapy (CBT) and Compassion Focused Therapy (CFT) principles can be used to support people with a learning disability to navigate the grieving process, as understood by the Dual-Process Model. Findings: This case study describes CBT formulation and assessment, and implementation of CBT and CFT strategies in a man with Williams syndrome, demonstrating improvements in mood, and a greater ability to turn towards suffering and experience both "Loss-" and "Restoration-Oriented" processing. Conclusion: CBT and CFT may be useful and appropriate modalities for clinicians to consider when supporting people with a learning disability to navigate loss, as understood through the Dual Process Model.
