Table II:
Construct validity determine by convergent and discriminant validity.
| Construct | Convergent | Discriminant (Fornell-Lacker) | |||
|---|---|---|---|---|---|
| Cronbach’s α | CR | AVE | M-SPADI Pain | M-SPADI Disability | |
| M-SPADI Pain | 0.923 | 0.942 | 0.766 | 0.875 | - |
| M-SPADI Disability | 0.984 | 0.957 | 0.736 | 0.834* | 0.858 |
Abbreviation - CR: composite reliability, AVE: extracted average variance (AVE), M-SPADI: Malay Shoulder Pain and Disability Index
Notes: * The number represented the correlation of a shared construct less than the correlation of each construct
