A) Test-retest involves administering the same scale to the same group of individuals at two different points in time to assess the consistency of their responses. This helps in determining the reliability of the scale.
B) Factor analysis helps in identifying the underlying dimensions or factors that contribute to the scale's scores. It is not specifically designed to test the reliability of a scale, though it can provide some evidence about the internal consistency.
C) Split-half involves dividing the scale into two halves and assessing whether the scores on each half are consistent. This helps in determining the internal consistency of the scale.
D) Parallel forms involve administering two different versions of the same scale to the same group of individuals to assess whether the scores on each version are consistent. This helps in determining the equivalence and consistency of different versions of the scale.
