Answer to Question #201287 in Psychology for Mihkayla Price

Question

1.          Researchers developed a new measure of resilience. They administered it twice to a sample of 700 primary school students from some of Adelaide’s lower socio-economic suburbs. The first time (T1) was when the students were in grade 3; the second time (T2) was when they were in grade 11. They found that at T1 the new measure correlated positively with a measure of dispositional perseverance, negatively with a measure of learned helplessness, and was not at all related to a measure of aesthetic values. They also found that student’s scores on the new measure correlated at .80 between T1 and T2. Finally, they found that the vast majority of participants who scored high on the new measure of resilience tended to give up when they got a bad mark at school. We would therefore conclude that the new measure…

Answer 1

We would therefore conclude that the new measure has good construct validity; poor predictive validity; good test-retest reliability.

The new measure was found to have a high correlation between T1 and T2, indicating that it had good construct validity. It was not, however, a good predictor of long-term resilience. Students tended to give up after receiving a low grade, indicating weak predictive validity. Furthermore, if the variable is to be utilized on a sample at two separate time periods, it must have high test-retest reliability (i.e. grade 3 and grade 11).
