Reliability if an item is dropped→W03，std.alpha會變成0.906，略高於overall的0.905
Item statistics→W03的r.cor=0.270→發現W03與其他題的相關性最低
真的要刪題，或許可以考慮W03。但WHOQOL-BREF應用度已經很廣泛，刪掉此題與其他研究的可比性會降低…
Conbarch’s alpha被詬病的是每題的貢獻度一樣，有可能被低估
可以改作Mcdonald’s omega assumptions (內在一致性結果會比較高)
文章發表Conbarch’s alpha還是占一席之地，原因是：大家比較習慣的用法、和其他問卷的COnbarch’s alpha有可比性
Mcdonald’s omega
#需要加裝package{GPArotation}

dta_2<-omega(dta[,27:54])
summary(dta_2)## Omega
## omega(m = dta[, 27:54])
## Alpha: 0.9
## G.6: 0.93
## Omega Hierarchical: 0.59
## Omega H asymptotic: 0.64
## Omega Total 0.92

## With eigenvalues of:
## g F1* F2* F3*
## 4.8 2.5 1.1 1.2
## The degrees of freedom for the model is 297 and the fit was 2.8
## The number of observations was 240 with Chi Square = 634.13 with prob < 0
##
## The root mean square of the residuals is 0.06
## The df corrected root mean square of the residuals is 0.07
##
## RMSEA and the 0.9 confidence intervals are 0.069 0.062 0.076
## BIC = -993.62Explained Common Variance of the general factor = 0.5
##
## Total, General and Subset omega for each subset
## g F1* F2* F3*
## Omega total for total scores and subscales 0.92 0.86 0.63 0.74
## Omega general for total scores and subscales 0.59 0.49 0.33 0.42
## Omega group for total scores and subscales 0.18 0.37 0.29 0.32Omega 結論
看Omega Total=0.92 略高於Conbrach’s alpha
但實際上COnbarch’s alpha已經很好了，也不太需要再做Omega

Reliability if an item is dropped→C29，std.alpha會變成0.928，略高於overall的0.927
Item statistics→C29的r.cor=0.230→發現C29與其他題的相關性最低
真的要刪題，或許可以考慮C29。但刪題後面臨的問題跟前面的WHOQOL-BREF一樣

處理方法有幾個選擇：
(1)放棄，宣布工具不適配
(2)修改工具，修到好為止
(3)增大樣本數，直到至少可以使用DWLS為止
(4)簡化邁進，用domain取代題目
