Lesson Plan

Detective Mind Blueprint

Students will learn to identify, challenge, and test unhelpful thoughts using CBT detective strategies—gathering evidence, exploring alternatives, and practicing through role-play.

This lesson builds core CBT skills for future counselors, enhancing critical thinking and evidence-based thought-testing to guide clients toward healthier thinking.

Audience

Graduate Counseling Class

Time

60 minutes

Approach

Interactive evidence-gathering, discussion, and role-play.

Prep

Review Materials and Setup Technology

15 minutes

Step 1

Suspect Your Thoughts Discussion

10 minutes

  • Introduce the notion of thoughts as hypotheses in CBT.
  • Use the Suspect Your Thoughts Discussion prompt to engage students:
    • What makes a thought ‘suspect’?
    • How can we gather evidence for it?
  • Solicit examples of common unhelpful thoughts from graduate counseling practice.

Step 2

Clue-Finding in Cognition Presentation

15 minutes

  • Display the Clue-Finding in Cognition slide deck.
  • Walk through each thought-testing step: identifying evidence for/against, detection of cognitive distortions.
  • Pause after key slides for small-group note annotations and quick Q&A.

Step 3

Thought Investigation Role-Play

20 minutes

  • Divide into pairs for the Thought Investigation Role-Play.
  • Role A: counselor guiding evidence collection; Role B: client presenting an upsetting thought.
  • After 10 minutes, swap roles and repeat.
  • Circulate to observe and offer coaching tips.

Step 4

Group Debrief and Alternative Thought Generation

10 minutes

  • Reconvene as a full group.
  • Invite each pair to share one insight and one challenge.
  • Collaboratively generate alternative, balanced thoughts based on discussed evidence.
  • Highlight how this maps onto client work.

Step 5

Weekly Reflection Journal Entry

5 minutes

  • Distribute the Weekly Reflection Journal Entry.
  • Instruct students to write brief reflections on how they’ll apply the detective approach in their counseling sessions.

Slide Deck

Clue-Finding in Cognition: CBT Thought Testing

Using a detective approach to identify, evaluate, and reframe unhelpful automatic thoughts.

Welcome everyone to our deep dive into CBT thought-testing. Introduce the detective analogy: we’re gathering clues to test our hypotheses (thoughts). Explain how this slide deck fits into the larger Detective Mind Blueprint.

Learning Objectives

By the end of this session, you will be able to:

  1. Identify automatic negative thoughts in clients’ narratives.
  2. Gather evidence for and against these thoughts.
  3. Spot common cognitive distortions.
  4. Generate balanced alternative thoughts.

Emphasize the learning objectives clearly so students know what they’ll gain.

CBT Thought-Testing Model

  1. Identify the automatic thought
  2. Gather evidence supporting the thought
  3. Gather evidence contradicting the thought
  4. Detect cognitive distortions
  5. Develop balanced alternative thoughts

Provide a high-level overview of the five steps in CBT thought-testing.

Step 1: Identify the Automatic Thought

• Ask the client to describe their immediate thought when upset.
• Listen for ‘always,’ ‘never,’ or emotional words.
• Record the exact wording.

Explain that automatic thoughts pop up in response to situations—often shorthand for deeper beliefs.

Step 2: Gather Evidence Supporting the Thought

• What facts or observations back up this thought?
• Client’s memories, behaviors, or external feedback.
• Rate confidence in the evidence (0–100%).

Distinguish between subjective impressions and objective data.

Step 3: Gather Evidence Against the Thought

• Identify facts that contradict the thought.
• Past successes, alternative interpretations, third-party views.
• Compare strength of supporting vs. opposing evidence.

Help students see that counter-examples are just as important.

Step 4: Detect Cognitive Distortions

Common distortions include:

  • All-or-nothing thinking
  • Overgeneralization
  • Catastrophizing
  • Mind reading
  • Emotional reasoning

Introduce common distortions: overgeneralization, catastrophizing, mind-reading, etc.

Step 5: Create Balanced Alternative Thoughts

• Combine evidence to craft a more realistic thought.
• Use neutral, non-extreme language.
• Example: “I stumbled, but overall I communicated well.”

Stress the shift from disproving to balancing thoughts.

Guided Practice Prompt

In pairs, choose a personal or hypothetical unhelpful thought.

  1. Identify the thought.
  2. List evidence for and against.
  3. Spot any distortions.
  4. Generate one balanced alternative thought.

Prepare students for active practice in the next segment.

Example Case: Sarah’s Presentation Anxiety

Situation: Sarah fears she “will embarrass herself” at work presentation.
• Evidence For: Voice shook once in practice.
• Evidence Against: Peers applauded trial run; she’s presented before successfully.
• Distortions: Catastrophizing, mind-reading.
• Alternative Thought: “I may be nervous, but I’ve prepared and can handle questions.”

Walk through this example, modeling each step on-screen.

Summary & Next Steps

• Reviewed five detective steps for thought-testing.
• Practice regularly to build reflexive skill.
• Next Session: Thought Investigation Role-Play and group debrief.

Summarize, link back to larger lesson plan, and preview next steps.

Activity

Thought Investigation Role-Play

Description: In pairs, students practice guiding a client through the CBT detective approach to identify, challenge, and reframe an unhelpful thought.
Time: 20 minutes
Materials: CBT Thought-Test Worksheet (printed or digital), role-scenario cards (optional)

Instructions

  1. Pair Formation & Role Assignment (2 minutes)
    • Divide the class into pairs.
    • Within each pair, assign Role A (Counselor) and Role B (Client).
    • Distribute one CBT Thought-Test Worksheet to each pair.
  2. Round 1 – Detective Inquiry (8 minutes)
    • Role B selects an unhelpful thought (either personal or from a provided scenario card).
    • Role A guides Role B through the five detective steps:
      1. Identify the automatic thought.
      2. Gather evidence supporting the thought.
      3. Gather evidence contradicting the thought.
      4. Detect cognitive distortions.
      5. Generate one balanced alternative thought.
    • Both partners document each step on the worksheet.






  1. Swap Roles (1 minute)
    • Partners switch roles.
    • Role B (former counselor) either chooses a new thought or uses the same thought for deeper practice.
  2. Round 2 – Reverse Inquiry (8 minutes)
    • Repeat the five steps with new roles.
    • Encourage the new counselor to experiment with different questioning styles (e.g., Socratic questions, scaling confidence).






  1. Pair Debrief (1 minute)
    • Within each pair, discuss:
      • What was most challenging about gathering evidence?
      • Which cognitive distortions were easiest to spot?
      • How did it feel to generate the balanced thought?

Discussion

Suspect Your Thoughts Discussion

Time: 10 minutes
Objective: Introduce the detective analogy and explore how to spot and gather evidence about unhelpful thoughts.

Instructions

  1. Individual Brainstorm (2 minutes)
    • Ask students to reflect on a recent moment when they noticed an unhelpful thought (personal or from practice).
    • Have them jot it down briefly.






  1. Define a “Suspect” Thought (3 minutes)
    • Pose the question: What characteristics make a thought “suspect” or worth investigating?
    • Prompts:
      • Does it use absolute words (always, never)?
      • Does it evoke strong emotions without clear facts?
      • Is it based on assumptions rather than evidence?










  1. Evidence-Gathering Strategies (3 minutes)
    • Ask: How might a detective (counselor) gather evidence for and against this thought?
    • Encourage students to list at least two strategies:
      • Reviewing specific memories or behaviors
      • Seeking client’s external feedback (e.g., colleague opinions)
      • Using rating scales (0–100% confidence)














  1. Small-Group Sharing (2 minutes)
    • In triads, students share their suspect thought and one evidence-gathering idea.
    • Group selects one example to report back briefly to the class.

Transition: Summarize key patterns of suspect thoughts and evidence methods. Then segue to the Clue-Finding in Cognition slide deck for a deeper dive into the five detective steps.

  1. Which part of the detective approach felt most useful or insightful for you? Why?





  2. Identify a common unhelpful thought you might encounter with a client. What evidence would you gather for and against this thought?





  3. How will you guide a client to create a balanced alternative thought? Describe one specific question or strategy you’ll use.
