Methodological designs are used to develop the validity and reliability of instruments to measure constructs used as variables in research. The process is lengthy and complex
The average length of researcher time required to develop a research tool to the point of appropriate use in a study is five years. Methodological studies include assessment of content validity, evaluation of the conceptual structure of a scale, construct validity, and assessment of reliability. A researcher is developing a tool to measure pre-delinquent behaviors in pre-adolescence. He has already reviewed the literature, gathered qualitative data from experts, pilot-tested hundreds of pre-delinquent preadolescents, and analyzed the findings. It is clear that the tool actually measures what it is supposed to measure. This reflects the tool's
a. Validity
b. Utilizability
c. Reliability
d. Lack of bias
ANS: A
Methodological designs are used to develop the validity and reliability of instruments to measure constructs used as variables in research. The process is lengthy and complex and should begin with a thorough literature review. Qualitative data is often collected when there is not much known about a construct and will allow the researcher to identify key factors/concepts associated with the construct which might be used to create a checklist.
Validity refers to a tool's ability to measure what the researcher intends it to measure.
