ASSIGNMENT 3: RELIABILITY AND VALIDITY IN RESEARCH
INSTRUMENTS QUESTIONS WITH 100% CORRECT ANSWERS| A+
GRADED
Score: 92.31 out of 100 - (ANSWERS)
A researcher develops a new instrument to measure coping skills and conducts a
pilot study to compare the new tool with an existing tool that measures this concept.
- (ANSWERS)Convergent validity
A researcher performs a series of pilot studies to evaluate whether a measurement
tool produces consistent results. - (ANSWERS)Reliability
A researcher develops a 7-point Likert scale to evaluate feelings of well-being in
patients who are undergoing chemotherapy. The researcher administers this measure
to other, similar patients in other medical centers. - (ANSWERS)Reliability
In a research study, ambulatory clinic nurses teach children with asthma how to
monitor peak expiratory flow volumes and how to use metered-dose inhalers to
determine whether asthma control scores improve. The researcher discovers
inconsistencies in how these measures were taught and how well the children
understood the concepts. - (ANSWERS)Intervention fidelity
A researcher reviews demographic characteristics of potential study subjects, such
as age and gender, to determine whether these characteristics may influence the
outcome of the study. - (ANSWERS)Internal validity
A researcher conducts a quasi-experimental study to determine whether there is
improved weight gain among premature infants who are fed according to cue-based
protocols. The researcher trained neonatal intensive care nurses to apply cue-based
feeding to orally fed infants and notes a statistical difference in weight gain between
infants fed according to cue-based protocols and those fed according to standard
protocols. The reviewer notes that parents who gave consent to participate in the
