Clinical and Research Utility of the Highly Sensitive Person Scale

This psychometric synthesis reviewed all 29 articles meeting criteria and possessing psychometric results from the 20-year history (1997 to 2017) of the Highly Sensitive Person Scale (HSPS). Aggregated internal consistency (coefficient alpha) was .874. Convergent comparisons were provided between the HSPS total score and 12 measures of constructs similar to the sensory processing sensitivity construct. Structural validity primarily supported both the original one- and three-factor models, as did the pattern of high intra-subscale and total scale correlations, but a unidimensional interpretation is suggested given the low reliabilities for subscale scores. The HSPS performed adequately for a screening-level instrument. Mental health counselors are well suited to use the HSPS within their regular practice of assessing and valuing normal human development in addition to diagnosing and treating mental health disorders.
