What type of validity is best represented in the following example?
Dr) Piper is conducting a research study that examines the relationship between height and bone fracture occurrences over 35 years. Dr. Piper measures adolescents' sitting height at age 15, and has them report number of annual bone fractures for the next 35 years. In his previous longitudinal research studies, Dr. Piper found that sitting height in adolescence is predictive of actual height in adulthood, so he is confident that by using sitting height at age 15 he has an adequate measure of the participants' actual height when they are 50 years old.
A) Internal validity
B) Construct validity
C) External validity
D) Logical validity

Construct validity refers to how well a test or tool measures the concept it's intended to measure. In this example, Dr. Piper is using sitting height at age 15 as a measure for actual height in adulthood, based on his previous findings that sitting height is predictive of adult height. This demonstrates construct validity because it shows that the measure (sitting height) accurately represents the concept being studied (actual height in adulthood).
