00:01
All right, so looking at reliability versus validity.
00:02
So reliability, so the consistency of a research instrument, it's going to measure the same way each time it is used under the same condition.
00:18
So it is, again, the consistency of a research instrument.
00:29
Instrument and then validity is the extent to which an instrument measures what it is supposed to measure.
00:40
So the extent to which an instrument measures what it's supposed to measure and then the procedures for validating instruments.
00:51
All right.
00:55
So we have self -structured.
01:04
So develop the instrument, pilot test, revise based on the feedback, and then conduct reliability reliability, and validity tests, and then adopted.
01:15
So use an existing validated instrument and verify its reliability and validity in the new context.
01:24
And then that's adopted and then adapted would be modify an existing instrument to suit new needs and then validate similar similar to a self -structured instrument.
01:42
And then differentiation between instruments.
01:45
So we have self -structured, adopted, and adapted again.
01:49
So self -structured would be created from scratch for a specific study.
01:55
Adopted would be used as is from previous studies without changes.
02:01
So as is.
02:02
And then adapted would be a modified version of an existing instrument to fit new requirements.
02:13
Now, conducting divergent and convergent validity on spss...
