Study Notes
Sampling
- Random selection guarantees a representative sample
- The risk of not achieving statistical conclusion validity increases when samples are too small
- Large samples are not a guarantee of accuracy
- A large nonprobability sample is better than a small one
- When evaluating sampling plans, consider the sampling strategy, the population, eligibility criteria, sample size, and rationale
- A description of the sample’s key characteristics should be included
Quantitative Data
- Structured data is quantifiable and gathered in a comparable way across participants
- Quantitative researchers aim for objective methods
- Self-report methods such as questionnaires and interviews allow researchers to gather data directly from participants
Self-Reports
- Structured self-report methods require pre-determined questions
- Open-ended questions offer rich information but are harder to analyze
- Open-ended questions can potentially reveal perspectives not accounted for in closed-ended questions
- Researchers may fail to include important responses in closed-ended formats
Advantages & Disadvantages of Self-Report Methods
- Questionnaires - less costly, advantageous for geographically dispersed samples, offer anonymity
- Interviews - higher response rates, feasible for populations unable to complete questionnaires, telephone interviews combine low cost with high response rates
Alternatives to Self-Report Methods
- Vignettes present brief situational descriptions
- Visual analog scales measure subjective experiences on a continuum
- Q-sorts involve participants sorting along specified dimensions
Observational Methods in Research
- Direct observation of behaviors can be an alternative to self-reports
- Observational methods can be used to gather information such as patient's conditions, verbal and nonverbal communication, activities, and environmental conditions
- Observers can focus on specific behaviors or broader defined events
- Observational biases can be minimized through training and monitoring observers
Category Systems
- Category systems are the basis for constructing checklists
- Exhaustive systems require all observed behaviors to be placed into a category for each unit of behavior, while nonexhaustive systems allow for unlisted behaviors
Rating Scales in Observational Methods
- Rating scales require observers to rate phenomena along a continuum
- Interrater reliability is crucial when multiple observers are involved
Biomarkers
- Biomarkers (biophysiological measures) can be used to:
- Explore basic biophysiological processes
- Investigate how nursing actions and interventions can affect physiological outcomes
- Evaluate new medical products or interventions
- Assess the accuracy of biophysiological information
- Examine correlates of physiological functioning
- Both in vivo (within a living organism) and in vitro (outside of a living organism) measurements are used in nursing research
Data Quality
- Training of individuals who collect and record data is a critical component of data quality
- Researchers must create conditions that ensure privacy and foster an open and honest atmosphere
- Measures used to operationalize constructs are paramount to data quality
Measurement
- Measurement involves assigning numbers to reflect the magnitude of an attribute present in a person or object
Validity
- Validity pertains to the degree to which an instrument measures what it claims to measure
- Different aspects of validity include face validity, content validity, criterion validity, and construct validity
- Cross-cultural validity evaluates the effectiveness of translated or culturally adapted measures across cultures
