有一點需要注意:6 D" ^( P( f4 ], m2 M& Q
: u' l- `8 {' v, V5 I4 v: OAdding 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).% q8 {% h, N6 s0 b( q
* [5 `5 q& a( L# ~1 l* T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。6 z! b2 n& k# `; i$ l/ @ {

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。
