此外,針對昨天提到的:

有一點需要注意:& O7 D# ^$ G ?. j8 G3 }
4 F( K* `2 Q$ J* R; a7 yAdding 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).7 w; @9 @# u; ?' u
/ v9 O# S5 \- \/ i M( 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。2 e/ v$ P: _0 G+ X+ P

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。" c) f+ z# f( X$ y; m
