The nature of mind scale (NOMS): Validation of an eight-dimensional scale assessing beliefs about the relationship between mind and matter
Year: 2025
Type: article
Abstract: We developed and validated the Nature of Mind Scale (NOMS), a 24-item measure assessing lay beliefs about eight distinct philosophical positions on the mind-body relationship. Given the limitations of existing measures and the theoretical diversity of mind-body positions, our goal was to develop a comprehensive yet practical scale that could capture the full range of philosophical stances without reducing them to overly simplified dimensions. Across four studies with 1074 participants, we established the NOMS's psychometric properties and nomological network. Through exploratory and confirmatory factor analyses, we identified an eight-factor structure representing belief in substance dualism, interactionism, panpsychism, idealism, reductive physicalism, non-reductive physicalism, mystical monism, and neutral monism. Participants most strongly endorsed interactionism, non-reductive physicalism, and mystical monism, while showing the least support for idealism. The scale demonstrated good model fit and strong evidence of measurement invariance across samples. Convergent validity was established through correlations with existing mind-body belief measures. Construct validity was supported by theoretically consistent relationships with religiosity, free will beliefs, cognitive style, personality traits, and afterlife beliefs. The NOMS represents an extension of previous measures of mind-body relations, capturing the multifaceted nature of these beliefs while maintaining sufficient brevity for practical research applications.
