the formative construct has to emit paths to (a) at least two reflective constructs( m& {# A, h! j, `

有一點需要注意:2 v5 O- w1 m4 b0 a8 O T
A- h' s! q9 RAdding 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).5 L. w' q2 ]# N0 t L0 F! w
3 R' {* W; o2 W) n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。

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。5 F u" {9 Q5 ]( L: x
