Title: | Different Version, Similar Result? A Critical Analysis of the Multiplicity of Shortened Versions of the Zimbardo Time Perspective Inventory | Contributor(s): | Perry, John L (author); Temple, Elizabeth C (author) ; Worrell, Frank C (author); Zivkovic, Urška (author); Mello, Zena R (author); Musil, Bojan (author); Cole, Jon C (author); McKay, Michael T (author) | Publication Date: | 2020-04-01 | Open Access: | Yes | DOI: | 10.1177/2158244020923351 | Handle Link: | https://hdl.handle.net/1959.11/30620 | Abstract: | The Zimbardo Time Perspective Inventory (ZTPI) has been extensively used, with more than 1,400 citations in Scopus alone. After identifying psychometric problems however, several authors have attempted to overcome limitations by shortening the scale. As such, there now exist multiple. shortened versions of the ZTPI, all using some of the original 56 items. Although each shorter version reports various broadly acceptable validity parameters using the group with which it was developed, these are often sample specific and at the cost of reliability, generalizability, and ability to detect individual differences in the construct. To examine this more closely, we reviewed the psychometric properties of the ZTPI and some of its derivatives, and found that data-driven approaches to creating these shortened versions of the scale prioritized improved model fit over internal reliability and sensitivity. In conclusion, we suggest that it is time for a new collaborative strategy to address conceptual and measurement concerns with the ZTPI, and discourage data-driven and sample-specific solutions to the psychometric concerns of the scale's scores. More broadly, we recommend that researchers consider the impact on reliability, generalizability, and ability to detect individual differences when developing short psychometric scales. | Publication Type: | Journal Article | Source of Publication: | Sage Open, 10(2), p. 1-15 | Publisher: | Sage Publications, Inc | Place of Publication: | United States of America | ISSN: | 2158-2440 | Fields of Research (FoR) 2008: | 170109 Personality, Abilities and Assessment | Fields of Research (FoR) 2020: | 520503 Personality and individual differences | Socio-Economic Objective (SEO) 2008: | 970117 Expanding Knowledge in Psychology and Cognitive Sciences | Socio-Economic Objective (SEO) 2020: | 280121 Expanding knowledge in psychology | Peer Reviewed: | Yes | HERDC Category Description: | C1 Refereed Article in a Scholarly Journal |
