What is the SCL-90 Test & Its Purpose?
The SCL-90, or Symptom Checklist-90, is a self-report questionnaire designed to evaluate a broad range of psychological problems and symptoms of psychopathology. It serves as a powerful screening tool that helps individuals identify patterns in their feelings, thoughts, and behaviors over the past week. Think of it not as a diagnosis, but as a detailed map highlighting areas of your emotional and mental landscape that may warrant closer attention. It's a foundational step for anyone looking to engage in meaningful self-reflection and understand their current state of mental wellbeing.

The History and Evolution of the Symptom Checklist 90
To appreciate the SCL-90, it's helpful to understand its roots. Developed by Dr. Leonard Derogatis in the 1970s, the Symptom Checklist 90 emerged from earlier versions as a refined and robust instrument for psychological assessment. Its creation was grounded in extensive clinical research, ensuring that the questions and dimensions were relevant and effective in capturing common psychological distress. Over the decades, it has been widely used by researchers and clinicians, cementing its reputation as a reliable and valid tool for measuring psychological symptoms. This long history provides a foundation of trust and scientific credibility.

Diving Deep: The SCL-90's 9 Symptom Dimensions Explained
The true power of the SCL-90 lies in its multidimensional approach. It doesn't just give you a single score; it breaks down your experience into nine distinct categories, offering a nuanced view of your mental wellbeing. Let's explore each of the SCL-90 dimensions.

Somatization: Physical Symptoms & Psychological Stress
This dimension measures the distress arising from perceptions of bodily dysfunction. It includes symptoms like headaches, dizziness, nausea, and muscle soreness that are often linked to psychological stress. A high score here might suggest that emotional turmoil is manifesting as physical discomfort. It’s a powerful reminder of the deep connection between mind and body.
Obsessive-Compulsive: Repetitive Thoughts and Behaviors
Here, the focus is on thoughts, impulses, and actions that are persistent, unwanted, and feel difficult to resist. This dimension reflects symptoms characteristic of obsessive-compulsive patterns, such as constant worrying, trouble making decisions, and feeling compelled to repeat certain actions. It highlights the struggle to control intrusive thoughts and behaviors.
Interpersonal Sensitivity: Navigating Social Interactions
This scale assesses feelings of personal inadequacy and inferiority, particularly in social situations. It taps into self-consciousness, uneasiness, and negative expectations about communicating with others. A high score may point to discomfort in social settings and a heightened sensitivity to the judgment of others, whether real or perceived.
Depression: Mood, Motivation, and Energy Levels
Reflecting a broad range of classic depressive symptoms, this dimension covers feelings of hopelessness, low mood, lack of energy, and loss of interest in life's pleasures. It offers a glimpse into your emotional core, assessing the presence of persistent sadness and a bleak outlook that can impact every aspect of daily functioning.
Anxiety: Worry, Tension, and Nervousness
This dimension captures signs of general anxiety, including nervousness, tension, trembling, and feelings of panic. It measures that persistent sense of dread or being "on edge" that can be both mentally and physically exhausting. Understanding your score here can be the first step toward managing worry and finding calm.
Hostility: Anger, Irritability, and Aggression
Hostility relates to thoughts, feelings, and actions that are characteristic of anger. This includes irritability, resentment, aggression, and a tendency to get into arguments. This dimension helps identify underlying anger that may be affecting your relationships and overall sense of peace.
Phobic Anxiety: Specific Fears and Avoidance
This scale measures persistent and irrational fear in response to specific people, places, objects, or situations. It reflects the kind of anxiety that leads to avoidance behaviors, such as a fear of open spaces (agoraphobia) or social situations (social phobia). It pinpoints specific triggers for intense fear.
Paranoid Ideation: Distrust and Suspicion
Paranoid ideation involves disordered thinking characterized by suspicion, fear of losing autonomy, and a sense of being watched or talked about. It assesses feelings of distrust and the belief that others may be trying to take advantage of you. This dimension sheds light on patterns of suspicious thought.
Psychoticism: Unusual Thoughts and Detachment
This scale is designed to identify a range of unusual thoughts and experiences, including feelings of social alienation, withdrawn behavior, and unconventional perceptual experiences. It represents a more schizotypal lifestyle and can indicate a sense of detachment from oneself and the surrounding world.
Interpreting Your SCL-90 Global Severity Index (GSI) & Other Scores
Once you complete the SCL-90, you'll see more than just the nine dimension scores. Several global indices provide a broader overview of your mental state. The most important of these is the Global Severity Index (GSI), which is considered the best single indicator of your current distress level. It's calculated from all 90 items and provides a summary of your overall psychological discomfort. To understand what this and other scores mean, you can explore your results.

What Do High SCL-90 Scores Indicate?
A high score on any of the nine dimensions or the GSI suggests a greater level of distress in that specific area. For example, a high score on the Depression scale may indicate you are experiencing significant depressive symptoms. It’s crucial to remember that a high score is not a diagnosis. Instead, it’s a signal—an invitation to explore that aspect of your life more deeply, perhaps with the help of a professional.
Beyond GSI: Understanding PSDI and PST
Besides the GSI, you might see two other scores. The Positive Symptom Distress Index (PSDI) measures the intensity of your symptoms, reflecting how much you are bothered by the issues you endorsed. The Positive Symptom Total (PST) simply counts the number of symptoms you reported. Together, these scores provide a comprehensive picture of both the breadth and depth of your psychological distress.

Common Questions About the SCL-90 Psychology Test
What is the SCL-90 test used for?
The SCL-90 is primarily used as a screening tool to assess a wide range of psychological symptoms and distress. It helps individuals gain insight into their emotional and mental wellbeing across nine key dimensions, making it an excellent starting point for personal growth and self-awareness.
Is an online SCL-90 assessment accurate?
When based on the original, scientifically validated questionnaire, an online SCL-90 is a reliable tool for self-assessment. While it provides valuable insights, it's important to answer the questions honestly. At PsychologyTest, we use a scientifically-backed version to ensure you receive a dependable anonymous mental health test.
What does a high score on any SCL-90 dimension mean?
A high score suggests that you are experiencing a significant level of distress related to that specific dimension (e.g., anxiety, depression). It is not a diagnosis but an indicator that this is an area of your life that may benefit from further attention, reflection, or professional support.
How long does the SCL-90 test take to complete?
The SCL-90 test consists of 90 short questions. Most people find they can complete it in about 15-20 minutes. It's best to set aside a quiet moment where you can reflect on your feelings over the past week without interruptions to ensure your answers are as accurate as possible.
Can the SCL-90 diagnose a mental health condition?
No, and this is a critical point. The SCL-90 is an informational screening tool, not a diagnostic instrument. It cannot and should not be used to diagnose any psychological disorder. The results are for educational and self-exploration purposes only. If you are concerned about your mental health, please consult a qualified healthcare professional for a proper diagnosis and treatment.
