The AI Addiction Scale (AIAS-21) is a concise, self-administered instrument designed to evaluate patterns of potentially problematic or addictive engagement with artificial intelligence (AI)-based technologies. These technologies may include conversational agents, generative applications, virtual companions, and other interactive AI systems increasingly integrated into everyday activities.

The scale comprises 21 items organized across seven empirically grounded dimensions reflective of core behavioral addiction constructs: compulsive use, craving, tolerance, withdrawal, preoccupation, continued use despite harm, and functional impairment. The AIAS-21 offers a structured framework for evaluating the extent and impact of AI use on an individual’s emotional, cognitive, and functional well-being.

Proposed Core Constructs for AI Addiction Scale (AIAS-21)

The constructs are partially derived from diagnostic criteria for behavioural and other addictions from DSM-5 and ICD-11 and adapted to fit AI-specific interactions. The constructs are as follows:

1. Compulsive Use / Loss of Control

2. Craving

3. Tolerance

4. Withdrawal

5. Preoccupation / Salience

6. Continued Use Despite Harm

7. Functional Impairment

Below is a 21-item AIAS-21, with 3 items per construct, all rated on a 5-point Likert scale.

Instructions

This questionnaire is designed to help you reflect on how you’ve been using artificial intelligence (AI) tools like chatbots, virtual assistants, or content generators over the past 6 months.

Please read each statement below and choose the answer that best describes how much you agree with it. There are no right or wrong answers—just go with what feels most accurate for you.

Use the following scale to answer:

| 1 = Strongly Disagree

| 2 = Disagree

| 3 = Neutral / Not Sure

| 4 = Agree

| 5 = Strongly Agree

Answer each question honestly. Your responses can give you insight into your habits and help identify whether AI use might be affecting your daily life.

Scoring Instructions

Add up your responses for all 21 items.

The minimum possible score is 21 (if answered 1 for every item).

The maximum possible score is 105 (if answered 5 for every item).

Higher scores suggest a greater probability of problematic or addictive AI use.

Score Range Interpretation

21–41 - Minimal risk – low involvement with AI

42–62 - Moderate risk – signs of problematic use

63–83 - High risk – likely problematic use

84–105 - Very high risk – possible addictive behavior; consider further evaluation

These thresholds are provisional and subject to validation in future empirical studies.

Note: This tool is intended for educational and self-reflection purposes. It is not a diagnostic instrument. If your AI use is causing distress or interfering with your life, consider speaking to a mental health professional.
