Internal consistency reliability:
Cronbach's alpha = .61 (time 1 and time 2) -> overall composite
Cronbach's alpha = .53 (time 1), .60 (time 2) -> positive composite
Cronbach's alpha = .45 (time 1), .46 (time 2) -> negative composite
Test-retest over a period of 6 months
: r = .53 (p<.001) - overall composite
r = .53 (p<.001) - positive composite
r = .38 (p<.001) - negative composite
Test-retest Reliability: r = .38-.53
Concurrent Validity: CASQ-R score were significantly positively correlated with scores on the VDI.
please help me on above scores, how to interpret this score. I am doing my presentation on children attributional style questionnaire(revised version). How to explain the above validity and reliability numbers in words. please help
