The 3S-FORM Model is the core of the Effectiveness Coaching methodology, distinguishing it by explicitly separating the client's internal work from the coach's process structure. It effectively integrates the need for internal growth (3S) with a structured path to results (FORM) (Lee, 2025).
The model is divided into two distinct but interconnected components:
- 3S: The Inner Growth Engine (Coachee's Role)
- FORM: The Coaching Process Structure (Coach's Role)
I. The Inner Growth Engine: The 3S
The 3S are the internal cognitive and emotional processes the client (coachee) must activate and manage to drive sustainable, long-term change. This is the Inner Growth Engine responsible for transforming simple awareness into meaningful insight and lasting action.
| Component | Description | Role in Change |
| Self-Awareness | Objectively recognizing one's current state, including behaviors, emotions, thought patterns, and the impact they have on others and results. | Clarifies Reality: Helps the coachee see the 'critical behavior' that prevents 'effective results.' |
| Self-Talk | The internal dialogue and beliefs a person holds about themselves, their potential, and the situation. This often involves identifying and challenging limiting beliefs. | Manages Mindset: Replaces self-defeating narratives with empowering and constructive self-statements, reinforcing commitment. |
| Self-Reflection | The deliberate process of reviewing experiences, comparing current actions to desired outcomes, and learning from successes and failures. | Sustains Learning: Develops the client's ability to be their own coach, ensuring growth continues autonomously after the engagement ends. |
The 3S process is often applied after conducting an ABC (Antecedent-Behavior-Consequence) analysis. The 3S helps the client change the Behavior (B) by influencing their mental model(internal beliefs and thoughts system) regarding the Antecedent (A) (trigger) and the desired Consequence (C) (called "effective results")(Lee, 2014; 2019).
II. The Coaching Process: FORM
The FORM is a structured, four-step process the coach uses to facilitate the conversation, ensure clarity, manage progress, and guide the coachee toward tangible results. This structure provides the external scaffolding for the client's internal 3S work.
| Stage | Process/Focus | Coach Action (What the Coach Facilitates) |
| Feedback | Exploring the current reality and the gap between the desired results and the actual outcomes. | Helps the client accept and process objective data (often from diagnostic tools) to define the specific Need for Change and the Critical Behavior. |
| Opportunity | Shifting the client's perspective from the 'problem' to the 'potential' and cultivating a growth-oriented mindset. | Frames challenges as opportunities for growth and helps the client broaden their range of possible solutions and actions. |
| Restructure | Challenging the client's assumptions and beliefs (often the negative Self-Talk from the 3S) to uncover new pathways to action. | Guides the client to shift perspective, establish new, effective beliefs, and commit to necessary behavioral changes. |
| Move Forward |
Defining concrete actions, anticipating obstacles, and securing commitment for execution. | Supports the client in creating a detailed action plan, monitoring progress, and reinforcing successful behavioral patterns for Effective Results. |
The power of the 3S-FORM model is its integration: The coach's structured FORM process constantly prompts and challenges the client to engage their 3S Inner Growth Engine, ensuring the resulting actions are internally motivated and therefore more likely to be sustained
