This is the core of what the report discusses. I have split the first paragraph into three, in the hope of making it easier to read, and explained a couple of sets of initials – I hope that's helpful.
"Chronic illness and the DPM [Disabled People's Movement]
Investigating a social model of disability in relation to the experience of chronic illness lays bare certain tensions and challenges. The concept of chronic illness is largely absent from both Disability Studies and disability activism in the UK. This occurred as ‘chronic illness’ became associated with an oppressive, medical model of disability. Indeed, many feel that chronic illness and the social model of disability are conceptually incompatible.
On the one hand, some in the DPM think people with chronic illness focus too much on impairment – on restriction, suffering and the pursuit of medical intervention – and see this as a betrayal of the social model of disability.
On the other hand, people with chronic illness think the social model does not apply to them because addressing external barriers and discriminatory attitudes doesn’t mitigate the impact of chronic illness enough to allow for social participation and inclusion. Thus, chronic illness and disability have been conceived of as different states.
We feel that these conceptual tensions create an impasse that prevents people with chronic illness from identifying and challenging the social and structural causes of our disadvantage. This makes it harder to claim our rights as disabled people. The aim of the CIIP [Chronic Illness Inclusion Project] was to explore whether and how the social model could be harnessed productively to support our own emancipation as disabled people."
Inevitably, it finds that some of the disability experienced by chronically ill people IS imposed on them socially – by disbelief, by a refusal to understand their experience ('Everyone gets tired'), by the attitude that chronically ill people don't deserve the definition 'disabled', by medical gaslighting, by a benefits system that constantly suggests they might be under surveillance for faking, etc. If we are to claim our rights and counter our exclusion, we have to challenge this.
