Trust in Teams and Trust in Leaders Scale: A Review of their Psychometric Properties and Item Selection

摘要

One objective of DRDC Toronto's Trust in Military Teams Applied Research Project (16kx) was to develop reliable and valid measures of trust in teams and leaders at the level of small military units (i.e., section level). Several research studies resulted in initial versions of two measures: the Trust in Teams and Trust in Leaders Scales. These initial versions of the scales were the subject of initial item selection, reliability, and validation analyses as documented in previous contractor reports (Adams, Bruyn, & Chung- Yan, 2004; Adams & Sartori, 2006). However, a recent review of the Trust in Teams and Trust in Leaders scale items in Adams and Sartori (2006) differed substantively from those in Adams, Bruyn, and Chung-Yan (2004). That is, some of the items were slightly reworded, whereas others were completely new, making direct comparisons and the continuity of scale development work from one version of the scale to the next a particular challenge. To address this issue, the current report represents a review of the literature concerning scale development analyses approaches with applications to second versions of the Trust in Teams and Trust in Leaders Scales to provide a sound psychometric basis for continued scale development work. To this end, we review the literature concerning the analytic approaches to favour for the evaluation and selection of items. We then re-analyze the data for the Trust in Teams and Trust in Leaders Scales and review the item selection based on these analytic approaches in order to provide a more robust basis for future scale work with these measures.
