In the current psychometric examination, results revealed strong support for both the temporal stability and construct validity of the SPIN, suggesting it is an appropriate screening measure for the assessment of social phobia in adolescents.

Clinical implications and suggestions for future research are discussed.

refers to the appropriateness of the content of an instrument.

In other words, do the measures (questions, observation logs, etc.) accurately assess what you want to know?Social phobia and social anxiety are highly prevalent psychological conditions in children and adolescents.Due to the known risks associated with the spectrum of social anxiety in youth, early detection with valid and reliable assessment measures is imperative.Recall that a sample should be an accurate representation of a population, because the total population may not be available.An instrument that is externally valid helps obtain population generalizability, or the degree to which a sample represents the population.(the process of developing, testing, and using the device).Instruments fall into two broad categories, researcher-completed and subject-completed, distinguished by those instruments that researchers administer versus those that are completed by participants.The combination of these aspects, alongside the SAT, is a more valid measure of the applicant’s potential for graduation, later social involvement, and generosity (alumni giving) toward the alma mater.Finally, the most useful instrument is both valid and reliable. It is a moderately reliable predictor of future success and a moderately valid measure of a student’s knowledge in Mathematics, Critical Reading, and Writing.This is particularly important with achievement tests.Consider that a test developer wants to maximize the validity of a unit test for 7th grade mathematics.
