Which Buddhists denominations agree with the difference between pain and suffering as in many DBT texts? Which disagree?

> 'Pain is inevitable. Suffering is optional.' I'm not sure I like the adjective 'optional' because I think it's insensitive to tell someone who's been injured that their suffering is some switch to easily flip (I don't have an issue with the nouns). I think 'not' is better than 'optional'. Anyhoo, many Dialectical Behavioural Therapy (DBT) texts seem to distinguish pain and suffering in other ways such as: - Psychology Today: The Dialectic of Pain: Synthesizing Acceptance and Change > Pain in life is inevitable, but suffering and misery are not. These can result from the way we respond to pain. The more we fight against it, the more likely we are to experience negative emotions, such as anger, hopelessness, and despair, and the harder it becomes to identify changes that can help. Like those Chinese finger-trap toys, the more forcefully we tug to release our index fingers, the more tightly ensnared they become. Calming down and taking stock of the situation opens the means to escape. - Wikipedia: Marsha M. Linehan (this quote has no source as of this writing) > Marsha M. Linehan (born May 5, 1943) is an American psychologist and author. She is the creator of dialectical behavior therapy (DBT), a type of psychotherapy that combines behavioral science with Buddhist concepts like acceptance and mindfulness. - And so on.
