Quotes from Lucy Johnstone on this framework
"The Power Threat Meaning Framework can be used as a way of helping people to create more hopeful narratives or stories about their lives and the difficulties they have faced or are still facing, instead of seeing themselves as blameworthy, weak, deficient or ‘mentally ill’. Lucy Johnstone
It highlights and clarifies the links between wider social factors such as poverty, discrimination and inequality, along with traumas such as abuse and violence, and the resulting emotional distress or troubled behaviour, whether it is confusion, fear, despair or troubled or troubling behaviour.
It also shows why those of us who do not have an obvious history of trauma or adversity can still struggle to find a sense of self-worth, meaning and identity. “ Lucy Johnstone

Quotes from Prof. John Cromby on this framework
“One of the most important aspects of the Framework is the attempt to outline typical patterns of meaning-based responses to threat. These patterns are both provisional and general, and frequently cut across psychiatric diagnostic categories.” John Cromby
“So the operation of power produces threats. These threats get mediated by different constellations of meaning and give rise to threat responses. From a diagnostic perspective, many of these responses are called symptoms.
Within the Framework they appear as meaningful responses to combinations of challenging or adverse circumstances. They are attempts to adapt, endure, keep safe, survive—even to thrive. The Framework considers how we make sense of these frequently difficult experiences, and how messages from wider society can increase feelings of shame, self-blame, isolation, fear, and guilt.” John Cromby
