How to Do a Thorough AA 4th Step Inventory (And Why the Right Worksheet Changes Everything)

If you've been circling Step 4 for a while, you're not alone. The AA 4th Step inventory is the one that stops more people in their tracks than any other step — not because it's impossible, but because most people don't know how to start. They sit down with a blank page, a vague memory of "resentments and fears," and zero structure.

That changes today.

This guide walks you through exactly what the Big Book says about the 4th Step, how to use a proper worksheet, and where to find the resources that make the whole process much less daunting.

What Is the AA 4th Step Inventory?

Step 4 in Alcoholics Anonymous asks us to make "a searching and fearless moral inventory of ourselves." It's drawn directly from Chapter 5 of the Big Book (How It Works), and it's the foundation for Steps 5, 6, and 8.

The inventory isn't a punishment or a shame exercise. It's more like clearing out a closet that's been full of old junk for years. You have to take everything out, look at it honestly, and decide what stays and what goes.

There are three main columns in a Big Book-style 4th Step inventory:

1. Who or what I resent (people, places, institutions, principles)

2. The cause — what happened that I'm still holding onto

3. How it affects me — which part of my life was threatened (self-esteem, security, ambitions, personal or sexual relations)

Then — and this is the critical piece that gets skipped — where was I at fault? That's the part that creates the shift.

Why the Right Worksheet Matters

Here's the honest truth: scribbling notes in a journal isn't the same as working a structured 4th Step.

The Big Book's format is intentional. The columns exist for a reason. When you use a proper 4th step inventory worksheet designed around the Big Book's instructions, a few things happen:

• You stay on track instead of spiraling into narrative storytelling

• You don't accidentally skip the "my part" column (the most important one)

• You have something organized and complete to bring to your sponsor for Step 5

• You can actually see your character defects emerge as patterns across multiple resentments

A loose-leaf notebook won't do that for you. A purpose-built AA 4th step inventory worksheet will.

The 4th, 5th, 6th, and 8th Steps Are Connected

One thing sponsors know that newcomers often don't: Steps 4, 5, 6, and 8 all use the same inventory material. You're not starting over for each step — you're building on and processing the same foundational work.

That's why having a complete packet designed to carry you through all four of those steps is so much more useful than a single worksheet.

The Complete 4th Step Inventory Packet from AAmazingTabs was built exactly for this — a Big Book companion that walks you through Steps 4, 5, 6, and 8 with purpose-built worksheets for each stage. You can also find it directly at the 4th Step Packet page. It takes the guesswork out of the format and gives you something real to work with.

How to Actually Start Your 4th Step

Here's a practical process that works:

Step 1: Set aside dedicated time. Don't try to squeeze this in between meetings. Give yourself quiet hours — morning works well for most people.

Step 2: Start with resentments. List every person, institution, or idea that you hold a resentment toward — no filtering. If it bugs you, it goes on the list.

Step 3: Work the columns. For each resentment, go through the Big Book's three columns: the cause, the part of self that was affected, and your role in it.

Step 4: Move to fears. Page 68 of the Big Book transitions into a fear inventory. Use the same column structure.

Step 5: Work the sex inventory. Page 69 covers this. It often requires honest conversations with a sponsor before you begin.

Step 6: Don't stop at the list. What you do with the inventory in Steps 5 and 6 is where the transformation happens.

Use a Sobriety App to Stay Accountable Between Sessions

One practical tool many people use alongside their written work is a sobriety app that provides daily reflections, step guidance, and encouragement between sponsor calls. The AABluebook — Sobriety App is designed specifically for AA members, with content aligned to the Big Book and the 12 Steps. It's worth adding to your toolkit as you move through Step 4 and beyond.

The Bottom Line

A thorough, well-structured AA 4th Step inventory is one of the most powerful things you will ever do in recovery. Don't shortchange it with a blank piece of paper. Use the right tools, work with your sponsor, and trust the process.
