Definitions 2 Validity is the extent to which a test measures what it claims to measure . It is vital for a test to be valid in for the results to be accurately applied . It is not determined by a single statistic , but by a body of research that demonstrates the relationship between the test and the behaviour it is intended to measure . There are three types of validity , content-validity , criterion-related validity and construct-validity (Wagner , n .d

Comprehensiveness is the ability of

a theory to explain broad variety of observations (Tharney , n .d

Applicability is the ability of a theory to be applicable or relevant to the matter at hand and that it can be used in an applied or practical setting (Tharney , n .d

Cultural utility is the ability of the theory to be useful in addressing societal problems . The best theory should contribute to the scientific understanding while fulfilling a societal need (Bush , 1945 It may also be defined as an extent to which a theory or test may be used to determine how cultural practices of a society may shape psychological processes (Markus , n .d
