Development and Validation of a VStitcher Competency Assessment Instrument for Apparel Students

---

Abstract

Confidence in the use of 3D design software like VStitcher has become an essential competency in apparel education, complementing traditional pattern drafting. This study developed and validated the VStitcher Competency Assessment Instrument to measure students’ self-efficacy and skill levels in 3D garment simulation. The instrument was administered to 37 students in two Digital Apparel Production courses as pre- and post-tests, assessing three dimensions: VStitcher General Usage (VGU), 2D-3D Competency (2D3D), and Self-Confidence in Using VStitcher (SCVS). Independent t-tests confirmed no major class differences, allowing for grouped analysis. Reliability testing revealed strong internal consistency for SCVS (a = 0.856-0.951), while VGU and 2D3D showed mixed reliability. SCVS scores significantly increased post-instruction (p = 0.007), indicating sensitivity to learning interventions. These results suggest that the instrument effectively captures confidence gains but requires refinement of knowledge-based subscales. Strengthening such assessments supports the integration of 3D technology and student preparedness for evolving industry demands.
