Verified step by step guidance

1. Step 1: Understand the question is asking about a psychological disorder that impacts daily functioning without an obvious external cause. This means the disorder is not directly triggered by a specific life event or substance use.
2. Step 2: Review the options: Adjustment disorders are typically linked to identifiable life events, so they have an external cause.
3. Step 3: Personality disorders often develop over time and can be influenced by trauma, which is an external factor, so they are not purely without external cause.
4. Step 4: Substance use disorders are caused by the use of substances, which is an external factor, so they do not fit the criteria.
5. Step 5: Anxiety disorders often affect daily functioning and can occur without a clear external cause, making them the best fit for the question.
