The passion scale: Aspects of reliability and validity of a new 8-item scale assessing passion.

Abstract

In this article, the psychometric properties of a new scale aimed at quantifying passion are explored, i.e. passion related to becoming good or achieving in some area/theme/skill.

The Passion Scale was designed to be quantitative, simple to administer, applicable for large-group testing, and reliable in monitoring passion.

A total of 126 participants between 18 and 47 years of age (mean age = 21.65, SD = 3.45) completed an assessment of Passion Scale, enabling us to investigate its feasibility, internal consistency, construct validity and test-retest reliability.

Feasibility: The overall pattern of results suggest that the scale for passion presented here is applicable for the age studied (18-47).

Internal consistency: All individual item scores correlated positively with the total score, with correlations ranging from 0.51 to 0.69. The Cronbach's alpha value for the standardized items was 0.86.

Construct validity: Pearson correlations coefficient between total score passion scale and Grit-S scale were 0.39 for adults, mean age 21.23 (SD = 3.45) (N = 107).

Test-retest reliability: Intraclass correlation coefficient (ICCs) between test and retest scores for the total score was 0.92.

These promising results warrant further development of the passion scale, including normalization based on a large, representative sample.
