Terms in this set (33)research design refers to the guidelines and procedures outlined for conducting a study and thereby addressing a research questions true blinding enhances the validity of an experiments design true qualitative research is performed to enable discovery when there is insufficient prior understanding of a topic, or when preconceived concepts and predefined tools have inadequately captured the phenomena of interest true in qualitative research designs, the subjects/informants experiences, actions, interactions, and social contexts are more important than those of the researcher true in descriptive research, the prevalence is the percentatge of people who have a particular health-related condition true in descriptive research, the incidence is the number of new cases of a disease or disability in a population during a specificied time period true in experimental design, subjects are assigned to one of two or more condition groups based on multiple criteria as selected by the investigator (e.g. subject demographics) false the selection of a research design weights heavily on multiple forms of validity, except for internal validity, which is a factor independent of design considerations false ethnography is concerned with sampling a population with strict inclusions and exclusions criteria false correlational research seeks to find usual or average values for specific variables, thus serving as a basis to evaluate and compare an individual against a similiar group false the possibility of failure to find and report a relationship among variables in a study when the relationships actually exists is a type 1 error false the biggest danger to scientific development is to report a relationship that does not exist. the is considered a type 2 error false a cohort design is implemented to follow a group over time utilizing repeated measures at certain intervals true participatory action research involves the participants in shaping the research questions, methods, and outcomes true a two-group posttest-only randomized experiment relies on groups being probabilistically equivalent true the selection of a research design weighs heavily on multiple forms of validity, except for internal validity, which is a factor independent of design considerations false in qualitative research, researchers should use theoretically defined statistical methods of sampling as required for making inferences about the population of interest false because sampling error represents the degree to which the sample is representative of the population, the larger the sample error, the less representative the sample is to the population and the lower the external validity true some examples of different types of performance sites in OT research include university lab facilities, inpatient units, outpatient rehabilitation centers, skilled nursing facilities, and community-based organizations true key considerations for sampling in qualitative research are appropriateness and adequacy false a key distinction of quantitative designs is that when securing a sample, it is acceptable that the researchers sampling plans change during the study (include the number, type, and description of the subjects to be studied) false a unit of analysis refers to the scale of measurement utilized when analyzing the demographics of a sample false the extent of rater bias is assessed through investigation of inter-rater reliability true the classical test theory is a set of psychometric approaches that aim to define the true score of an assessment by isolating the error of measurement from the achieved score false medical records can be extract a wide range of information that might be important to a researcher when using a historical preexisting documents review approach. Typically, this does not require any informed consent or institutional review board (IRB) approval. false A disadvantage of standardized tests and performance measures is that they are not all cross-cultural in nature and may not be relevant to all sociodemographic and sociocultural groups. true The methodological rigor of data collection depends on whether there is evidence in the literature that a quantitative instrument is valid and reliable or that a qualitative strategy is trustworthy. true operationalizing a construct refers to assigning a concrete means of defining an abstract idea, such as a measurement true Professional and ethical considerations ensure safe and humane treatment of research participants. true There are a wide variety of approaches to data collection that may be utilized in occupational therapy (OT), including observations, interviews, self-reported measures, standardized tests and performance measures. true Researchers must ensure that participants are clear in their understanding of the limits of the researcher's role and the availability of their care; therefore, researchers should avoid establishing rapport with participants or responding empathically during interactions. false one of the most important and effective ways to reduce the measurement error of an assessment is to standardize it true if subject is unduly high in a study, it will likely lead to low participation rates and high dropout rates true Students also viewedHIST FINAL EXAM REVIEW101 terms gracejanak Chapter Five Vocabulary10 terms Josephine_Jipping Cardiovascular61 terms angus_winwoodPlus theo 3-432 terms gracejanak Other sets by this creatoradult exam 2 practice questions5 terms wendyhall17 SCI adult chapter 36105 terms wendyhall17 Adult ppts exam 274 terms wendyhall17 data collection and measurement38 terms wendyhall17 Other Quizlet setsCAS 100A Exam29 terms Carson_Lortz HVV M-240 terms GOROSPE_FERDINAND AP US Government16 terms Amitoj1Plus Chapter 12 Procedures for Complete Body Massages57 terms Jamie_Orme5 Which of the following is most important to the researcher in selecting a research design?Which of the following is most important to the researcher in selecting a research design?
