The terms "psychological disorder" and "mental illness" are often used interchangeably, but there are subtle differences.
Psychological Disorder
A psychological disorder refers to a pattern of thoughts, feelings, and behaviors that cause significant distress or impairment in a person's life. It is diagnosed based on specific criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
- Examples: Anxiety disorders, depression, obsessive-compulsive disorder (OCD), schizophrenia, and bipolar disorder.
Mental Illness
Mental illness is a broader term that encompasses any condition that affects a person's thinking, feeling, or behavior. It can include psychological disorders, but also other conditions that may not meet the strict criteria for a disorder.
- Examples: Stress, grief, trauma, and substance abuse.
Key Difference: The main difference lies in the level of severity and impact on daily functioning. A psychological disorder is a more specific and diagnosable condition that significantly disrupts a person's life. Mental illness is a broader term that may include a range of conditions, including those that are not necessarily considered disorders.
In summary:
- Psychological disorder: A diagnosable condition with specific criteria that significantly disrupts a person's life.
- Mental illness: A broader term encompassing a range of conditions affecting thinking, feeling, or behavior, including psychological disorders.
