Exam 8: Clarifying Quantitative Research Designs

Which action will the researcher take to improve construct validity?

A nurse conducts a study to see whether there are differences in the number of books Latino parents and the number of books African-American parents read to their toddlers each week.Which type of study will this researcher utilize?

In a quasi-experimental study design,the group that receives standard care is usually referred to as the:

A researcher wishes to conduct a correlational study to determine whether there is a relationship between stress levels and relapse rates among patients who have chronic conditions.In order to determine the existence of a relationship between these two variables,the researcher will attempt to:

A researcher conducts a study to examine possible contributors to glycemic control in a group of subjects who have type 2 diabetes mellitus in a local community.A convenience sample of patients includes patients from 28 to 65 years old who range in weight from normal to obese,with time since diagnosis ranging from several months to several years.To determine causality in this study,the researcher will:

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.This represents a lack of:

In a study to examine the effects of a newly modified anxiety-reducing nursing action on a group of subjects who have cancer,the control group will receive:

In order to attribute causality of a posttest measure in an experimental study,the independent variable will be:

Which type of research design focuses on implementation of a treatment by the researcher?

A researcher wishes to conduct a study of a small number of subjects on a large hospital intensive care unit.To minimize problems associated with extraneous variables in the study setting,the researcher will:

In a quasi-experimental study examining the effects of nonpharmacologic treatments on postoperative pain management,the researcher trains nursing staff so that all experimental group subjects receive the same types of treatments.This is an example of:

A nurse researcher conducts a study to determine whether women who breastfeed their infants experience better sleep in the first two postpartum months.This study will employ which type of research design?

Multiple replications of an initial study conducted in different populations produce findings that do not match those in the initial study.The initial study may lack which type of validity?

In order to increase participation among potential subjects of a larger population,the researcher will:

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.This is done to help ensure:

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.Which might be a threat to internal validity in this study?

Which type of study is considered strongest for testing the effectiveness of an intervention?

If a researcher wishes to describe variables and to examine many relationships in a study,which type of study design will the researcher employ?

A researcher conducts a quasi-experimental study to determine whether there is appropriate 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 critiquing the study notes that not all nurses completed the cue-based feeding module.This would affect which type of validity?

A researcher administers a written test to evaluate knowledge of insulin administration and glucose monitoring to a group of subjects at annual intervals over the next decade.This is an example of which type of study design?
