Exam 8: Clarifying Quantitative Research Designs

An important measure to decrease threats to internal validity in an experimental study is to

Which statement is true about a cross-sectional design?

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?

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

To attribute causality of a posttest measure in an experimental study,the independent variable will be

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

Which action will the researcher take to improve construct validity?

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

A nurse researcher monitors women with breast cancer for depression before and throughout their chemotherapy treatment.This is an example of which type of study design?

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 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?

A study in which subjects are assigned by the researcher into experimental and control groups increases

In a quasi-experimental study using a convenience sample of subjects from a local high school,the researcher asks potential subjects to volunteer for placement in either a "low sugar" diet program or a "regular sugar" diet program.This technique for assigning participation may compromise

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.To determine the existence of a relationship between these two variables,the researcher will attempt to

Which statement is true about a descriptive study design?

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?

A nurse researcher wishes to identify rates of pertussis infection in children less than 1 year of age and then again at 6 years of age to examine the relationship of immunization status on infection rates in this population.This is an example of which type of study design?

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

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.This is a threat to
