Influence Evaluation and Confounding Treatment between Psychological and Physical Symptoms in UPI Based on Lift-value in Association Analysis

Abstract

The UPI (University Personality Inventory) is a mental health check in which respondents answer yes or no to whether the symptoms indicated by each question match their own symptoms. The UPI consists of a questionnaire asking the presence of mental symptoms and a questionnaire asking the presence of physical symptoms. In this paper, we find strong causal relationships between mental symptoms and physical symptoms in UPI by calculating lift-value used in marketing. Then, by visualizing them as a network, we try to understand the overall causal relationships between mental and physical symptoms and obtain knowledge that can contribute to health of students. We also try to remove confounding from these lift-value. Confounding is the creation of spurious causal relationships by confounding factors. This paper has significance because 1) it shows effectiveness of using marketing methods to address health sector problem, and 2) it focuses confounding problem in association rules.
