Supplementary file 1_Perceived exertion as a moderator of psychological changes during nat

A dataset from a clinical trial analyzes perceived exertion as a moderator of psychological changes during surf or hike therapy for 86 active-duty U.S. service members with major depressive disorder. The data includes weekly assessments of exertion, depression/anxiety, and positive affect scores across six therapy sessions. The dataset was authored by Nicholas P. Otis and last updated in April 2026.

Use Cases

• Modeling the relationship between perceived exertion and changes in depression/anxiety scores based on session data.
• Comparing the moderating effect of exertion between different nature-based exercise therapies (surf vs. hike).
• Analyzing longitudinal changes in positive affect across multiple therapy sessions.
• Investigating potential treatment recommendations for depression based on activity-specific exertion levels.

Strengths

• Data originates from a randomized clinical trial with 86 participants, providing a structured research foundation.
• Includes repeated measures across six weekly therapy sessions for longitudinal analysis.
• Uses standardized psychological assessment tools (PHQ-4, Positive Affect Schedule).

Limitations

• Dataset is very small at 35.9 KB, indicating limited scope and sample size.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
