Research Design
NPTE Research & EBP
| Question | Answer |
|---|---|
| Historical research | investigates data sources for authenticity and worth |
| descriptive research | collects data about conditions, attitudes or charactheristics of a group |
| types of descriptive research | case studies, developmental, longitudinal, normative, qualitative |
| case studies | investigation of individual, group |
| developmental R | studies of behaviors that differentiate individuals at different ages, growth, maturation |
| longitudinal studies | changes over time |
| normative R | standards of behavior, standard values of given characteristics |
| qualitative R | seeks facts or causes of social phenomena |
| Correlational R | determine relationship between 2 variables |
| Limitation of correlational R | cannot establish cause & effect, may fail to consider all variables in relationship |
| Correlation coefficient | degree of relationship between variables |
| Correl Coeff near +1.00 | positively correlated |
| Correl Coeff near 0.00 | variables not related |
| Correl Coeff near -1.00 | inversely correlated |
| Types of correlational R | retrospective, prospective, descriptive, predictive |
| Retrospective R | investigates data collected in past |
| Prospective R | investigation of current data |
| Descriptive R | investigation of several variabless, determines existing relationships among variables |
| Predictive R | useful to develop predictive models |
| Experimental R | attempts to define a cause and effect relationship by group comparisons |
| Types of experimental R | True experimental, cohort design, within subject (repeated measures), between subject design, single subject design, factorial design |
| True experimental design | random assignment into experiemental or control group |
| Cohort design | quasi-experimental design. Subjects ID and followed over time for changes following intervention. Lacks randomization, may not have a control group |
| Within Subject Design | AKA Repeated Measures. subjects serve as own controls, random assignment to tx or no tx. |
| Between Subject Design | comparisons made between groups |
| Single Subject Experimental design | involves a sample of one with repeated measurements and design phases (AB, ABA, ABAB) |
| A-B design | SSED - 2 phases - a pretreatment and a treatment phase. |
| A-B-A design | Baseline phase, treatment phase, second baseline phase |
| A-B-A-B design | baseline, treatment, baseline, treatment |
| Factorial Design | number of independent variables utilized |
| Causal-Comparative R | attempts to define a cause-effect relationship through group comparisons |
| Ex post facto R | independent variable has already occurred and cannot be manipulated. Groups compared based on dependent variable |
| Epidemiology R | study of disease frequency & distribution |
