A longitudinal formulation based on Fennell's cognitive model of low self-esteem — mapping how early experiences created a negative bottom line that is maintained by biased processing and unhelpful rules.
This formulation maps how early experiences led to a core negative belief about yourself (the "bottom line"), the rules you developed to cope, what happens when those rules are triggered or broken, and how biased thinking and safety behaviours prevent the bottom line from ever being updated. Work through it with your therapist.
Use when low self-esteem is a primary maintaining factor in the client's presentation, following Fennell's (1997) cognitive model. This formulation maps how a negative core belief about the self generates anxious predictions, avoidance, self-critical thinking, and confirmatory biases that maintain low self-esteem. Particularly appropriate when self-esteem difficulties predate or transcend specific mood episodes.
Present the model: 'There's a well-established model of how low self-esteem maintains itself, and I think it fits your experience. Let's map it out together so we can see exactly how the negative belief about yourself keeps getting confirmed, even when the evidence doesn't support it.'
For clients unfamiliar with CBT formulation, walk through each component with concrete personal examples before attempting the full diagram. For those who find Fennell's full model too complex, focus on the maintaining cycle before connecting it to early experience. Use colour coding to distinguish maintaining factors from historical factors.
Not suitable if the client's self-esteem difficulties are primarily situational rather than characterological, in which case a simpler cross-sectional formulation may suffice. Be cautious with clients who may experience the formulation as confirmation of their negative self-view rather than an explanation of the maintenance process.
The two maintaining pathways in Fennell's model (the anxious predictions pathway and the self-critical pathway triggered when the rule is broken) should both be mapped. Ensure the client can see that the formulation explains the process, not the person. Use the formulation to generate specific intervention targets and explain the rationale for each technique.
Suitable for clients working with low self-esteem, formulation, fennell, cbt, core beliefs, bottom line, rules for living. This tool can be used as a standalone worksheet or as part of a structured homework plan.
