Verified step by step guidance

1. Step 1: Understand the nature of depression as a psychological disorder, recognizing that it is influenced by multiple factors rather than a single cause.
2. Step 2: Review research findings that highlight the role of both genetic predispositions (hereditary factors) and environmental influences (such as life stressors, trauma, and social context) in the development of depression.
3. Step 3: Evaluate the incorrect statements by considering evidence that depression can occur even without a family history, that medication alone may not fully cure all cases, and that it is not caused solely by a chemical imbalance but involves complex interactions.
4. Step 4: Conclude that the most accurate understanding is that both genetic and environmental factors contribute to depression, reflecting the biopsychosocial model of mental health.
5. Step 5: Summarize that effective treatment and understanding of depression require considering multiple influences rather than attributing it to a single cause.
