2. METHOD  2.1. Survey instrument and measurement  A brief description of chatbots was provided in the form prior to the survey. All constructs were measured using existing scales adopted and modified from extant iterature to ensure the validity and reliability of the model. Usability used the 5-item scale from Rose et al. 36] and Finstad [15]. Responsiveness adopted a 4-item scale from Roy et al. [38] and Chung et al. [10]. Perceived rust was measured with 4 items from Roy et al. [37], Ponte et al. [34], and Zhang et al. [54]. The scale to assess empathy included 7 items from Orden-Mejia and Huertas [29]. Accessibility used the 4-item scale from Orden-Mejia and Huertas [29]. Finally, to measure customer satisfaction, a scale consisting of 4 items from Rose et al. [36] and Pappas et al. [30] was adopted. 5- point Likert type scale was used to measure all constructs, ranging 1 — Strongly disagree to 5 — Strongly agree.
