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.
Researchers chose which type of instrument, or instruments, to use based on the research question.
Examples are listed below: is the extent to which an instrument measures what it is supposed to measure and performs as it is designed to perform.
Some qualitative researchers reject the concept of validity due to the constructivist viewpoint that reality is unique to the individual, and cannot be generalized.
These researchers argue for a different standard for judging research quality.
Thus far, we have discussed Instrumentation as related to mostly quantitative measurement.
Establishing validity and reliability in qualitative research can be less precise, though participant/member checks, peer evaluation (another researcher checks the researcher’s inferences based on the instrument (Denzin & Lincoln, 2005), and multiple methods (keyword: ), are convincingly used.
(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.
