As per Gaskin, this is mentioned in some scholarly works.He further mentioned that the Composite Reliability establishes that the constuct can be retained even when AVE is less that .5. Note that internal consistency reliability, including both Cronbach alpha and composite reliability, can be too high. According to Hair, Hult, Ringle, and Sarstedt (2014) the minimum composite reliability value in the PLS-SEM analysis should exceed 0.7. Composite reliability (sometimes called construct reliability) is a measure of internal consistency in scale items, much like Cronbach’s alpha (Netemeyer, 2003).. Partial Least Squares (PLS) focuses on the prediction of a specific set of hypothesized relationships that maximizes the explained variance in the dependent variables (Hair, Ringle, & Sarstedt, 2011). Nilai batas (cut off) uji construct reliability diterima apabila nilainya > 0.70, namun jika penelitian masih bersifat eksplanatori nilai di bawah 0.7 masih diterima. Composite Reliability (CR) lebih baik dalam mengukur internal consistency dibandingkan Cronbach’s Alpha dalam SEM karena CR tidak mengasumsikan kesamaan bobot dari setiap indikator. Table 2 – Reliability and Convergent Validity Measures Construct Indicator Indicator loadings Cronbach Alpha Composite Reliability AVE CB-SEM PLS - SEM CB-SEM PLS - SEM CB-SEM PLS - SEM CB-SEM PLS - SEM Attention and Interest in Terrorism in Media V1 0.86 0.87 0.95 0.95 0.96 0.75 0.79 V2 0.92 0.91 V3 0.92 0.91 V4 0.86 0.89 Dropping indicators further is not possible. Feature: Composite reliability roh_A bootstrap results Feature: PLS-POS: Option to use the FIMIX-PLS segmentation result as starting partition Feature: PLS-POS: … It can be thought of as being equal to the total amount of true score variance relative to the total scale score variance (Brunner & Süß, 2005). Estimation of composite reliability for congeneric measures. Sedangkan eror (e) berasal dari measurement eror dari masing-masing indikator : (1- Loading 2). According to Hair, Hult, Ringle, and Sarstedt (2014) the minimum composite reliability value in the PLS-SEM analysis should exceed 0.7. (1997). Because indicators are not equally reliable, composite reliability, which is weighted, is more accurate then Cronbach alpha (unweighted), and therefore CR should be assessed and reported (Hair et al., 2019). Kindly give your expert opinion. The above list provides an overview of points to consider when deciding whether PLS is an appropriate SEM method for a study. Raykov, Tenko. PLS-Graph reports composite reliability (CR) and average variance extracted (AVE) for content validity and discriminant validity. Dimana nilai standar loading berasal dari nilai standardized loading untuk tiap-tiap indikator (hasil output AMOS, Lisrel). Applied Psychological Measurement, 21(2), 173-184. I am running PLS SEM and has come across this situation. Cronbach’s Alpha cenderung menaksir lebih rendah construct reliability dibandingkan Composite Reliability (CR). Sample size.
