有一點需要注意:
' B6 u9 G$ d o& h N7 a
0 S- U& E P; kAdding consequence reflective constructs (e.g., Y and Z) to the focal formative construct (e.g., X) to attain model identification makes the estimate of parameters associated with the focal construct (X) a function of the selection of the external constructs (Y and Z) (Diamantopoulos, 2006), and hence causes potential interpretational confounding (Howell et al., 2007).2 Q1 S u) |! ^
" c- \. q: @( j; r, N. H以上問題在於,X's indicators與X之間關係的估計會因選擇Y and Z or 其他不同的構念而不同,但在整個nomological network來看,應該是X影響Y and Z,讓Y and Z來影響X的參數不太合理。/ a9 e) Z& ~& d- F5 h$ y
2 l$ F' s8 _ I' g: S因此,設計問卷時加上兩題的overall measurement當成reflective indicator好像會合理一點,如此這個構念會更有彈性放在模型內的任何地方。6 o# \$ T9 n/ V% u4 ?
