Background
Megalophobia severity screening scale (MSSS) is a self-report psychological assessment designed to measure fear, anxiety, discomfort, and avoidance related to extremely large objects, structures, environments, or entities. The scale evaluates emotional reactions, visual discomfort, intimidation responses, avoidance behaviors, and anxiety associated with oversized man-made or natural objects.
The MSSS-20 measures several dimensions including size-related fear, environmental intimidation, emotional anxiety, behavioral avoidance, and discomfort associated with oversized structures or objects. The assessment may help individuals better understand their emotional and behavioral responses to large-scale environments and visually overwhelming situations.
Procedure
Read each statement carefully and select the response that best describes your usual thoughts, feelings, or behaviors related to very large objects, oversized structures, enormous environments, or massive visual stimuli. Answer honestly based on your typical experiences rather than isolated situations.
Participation
Megalophobia test is interactive version and it is intended for educational, research, screening, and self-reflection purposes only. The self-test is not designed to provide a formal psychological diagnosis.
Scoring & Interpretation
Each item is rated using a five-point agreement scale. The assessment includes both forward-scored and reverse-scored items. Higher scores generally indicate stronger fear, anxiety, discomfort, intimidation, avoidance, and emotional distress related to very large objects or environments.
Results include an Overall Index Score and scores for four dimensions: Size Fear, Environmental Anxiety, Object Avoidance, and Visual Discomfort.
Dimension scores are standardized to a 0–100 scale and interpreted using qualitative categories.
Overall results are classified into five interpretive ranges:
• Minimal (0–20)
• Mild (21–40)
• Moderate (41–60)
• High (61–80)
• Very High (81–100)
