IOP2601 Assignment 3 (QUALITY ANSWERS)
Semester 1
Score: 92.31 out of 100
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. ...ANSWER...Convergent validity
A researcher performs a series of pilot studies to evaluate whether a measurement tool
produces consistent results. ...ANSWER...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. ...ANSWER...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. ...ANSWER...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. ...ANSWER...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 study
were from a higher socioeconomic class than the population as a whole. This is a threat
to: ...ANSWER...External validity
A researcher uses only one method of measurement to assess depression in older
adults living in an assisted living facility. ...ANSWER...Mono-operation bias
