The purpose of this study was to develop a time continuity scale and examine its reliability and validity. A total of 335 undergraduates completed a questionnaire twice. The questionnaire consisted of a time continuity scale that contained items collected from participants’ descriptions in previous researches, and 2 other scales assessing time attitude and time orientation. Exploratory factor analysis identified 2 distinct factors, “continuity between past and present" and “continuity between present and future," as hypothesized on the basis of existing theories. These subscales had adequate internal consistency and test-retest reliability. The construct validity of this scale was examined by calculating the correlations between its scores and scores on the 2 other scales.
