Research Process Dr Asha P Shetty
Research process • Process=a course of action or proceeding, which can be followed for doing something. • The research process describes the steps that one needs to follow for conducting research. • The progression of activities differs for qualitative and quantitative
Phase 1:The conceptual phase • Formulating and delimiting the problem • Reviewing the related literature • Undertaking clinical field work • Defining the framework / developing conceptual definitions • Formulating hypothesis Phase 2:The design and planning phase • Selecting a research design • Developing a intervention protocols • Identifying the population • Designing the sampling plan • Specifying methods to measure research variables • Developing methods to safe guard subjects • Finalizing the research plan Phase 3:The empirical phase • Collecting the data • Preparing the data for analysis Phase 4:The analytic phase • Analyzing the data • Interpreting the results Phase 5:The dissemination phase • Communicating the findings • Utilizing the findings in practice
Phases in a Quantitative Study • Phase 1: Conceptual Phase • Phase 2: Design and Planning Phase • Phase 3: Empirical Phase • Phase 4: Analytic Phase • Phase 5: Dissemination Phase
Phase 1: Conceptual Phase • Involves activities with strong conceptual or intellectual element. E.g. Reading, theorizing, reviewing ideas with colleagues or advisors. • Involves in skills such as creativity, deductive reasoning, insight and firm grounding in previous research.
Phase 1: Conceptual Phase • Formulating/delimiting the problem • Reviewing related literature • Undertaking clinical fieldwork • Defining the framework and developing conceptual definitions • Formulating hypotheses
Step I: Formulating/delimiting the problem • Identify an interesting , significant research problems and good research questions. criteria of good research problem
Step 2: Reviewing related literature Well before any data is collected • What is already known • Gives the base for new evidence
Step 3: Undertaking clinical fieldwork • Clinical field work provides perspectives on recent clinical trends, current diagnostic procedures, relevant health care delivery models. • Helps to understand clients and their settings.
Step 4: Defining the framework and developing conceptual definitions • Theory is the ultimate aim of science • Develop conceptual definitions.
Step 5: Formulating hypotheses • Statement of researchers expectations about relationships between study variables. For e.g.: Is preeclamptic toxemia related to stress factors during pregnancy? • H1:Women with higher incidence of stressful events during pregnancy will be more likely than women with lower incidence of stress to experience preeclamptic toxemia.
Phase 2: Design and Planning Phase • Make decisions about the methods and procedures to be used. • Plan of actual data collection
Phase 2: Design and Planning Phase 6. Selecting a research design 7. Developing intervention protocols 8. Identifying the population 9. Designing the sampling plan 10. Specifying methods to measure variables and collect data 11. Developing methods to protect human / animals rights 12. Finalizing the research plan
Step 6. Selecting a research design • The research design is the architectural backbone of the study. • Over all plan for obtaining answers to the questions being studied. • Specify which design is adopted • What will be done to minimize the bias? • How often data will be collected? • What type of comparisons will be made? • Where the study will take place?
Step 7. Developing intervention protocols • Develop intervention protocol • For e.g. if we are interested in testing the effect of biofeedback in treating hypertension. • Specify what biofeedback treatment would entail- who would administer, how frequently, over how long period…
Step 8: Identifying the population • Characteristics of study participants • Whom to generalize findings?
Step 9:Designing the sampling plan • Representativeness • Sampling plan specifies in advance how the sample will be selected and recruited, and how many subjects will be there.
Step 10: Specifying methods to measure variables and collect data • Self reports- interviews • Observation • Bio-physiologic measurements • The task of measuring research variables and developing a data collection plan is a complex and challenging process
Step 11: Developing methods to protect human/animals rights • Most studies involve human subjects. • Develop procedures to ensure study adhere ethical principles • Each aspect to be scrutinized to determine rights of subjects adequately protected
Step 12: Finalizing the research plan • Readability of written material • Pretesting measuring instruments • Critique by colleagues, peers to get substantive, clinical or methodologic feedback • Proposal for funding.
Phase 3: Empirical Phase • Collecting the data Procedures for actual data collection Where and when data will be gathered? • Preparing data for analysis • Coding- process of translating verbal data into numeric form • Patient response to Gender • A. Male-----------1 • B. Female --------2
Phase 4: Analytic Phase • Analyzing the data Statistical analyses 16. Interpreting results Interpretation: process of making sense of study results and of examining their implications. Determine how findings can best be used in clinical practice. What further research is needed before utilization can be recommended
Phase 5: Dissemination Phase • Communicating the findings: RESEARCH REPORT- term papers, dissertations, journal articles, presentations at conferences. 18.Utilizing findings in practice Plan for its use in clinical settings
Activities in a Qualitative Study • Conceptualizing and Planning the Study • Conducting the Study • Disseminating the Findings
Activities in a Qualitative Study(cont’d) • Conceptualizing and Planning the Study • Identifying the research problem: Begin with a broad topic- poorly understood, little is known • The general topic is narrowed and clarified Doing a literature review • Prior studies might influence their conceptualization of phenomena under study. • Phenomenon should be elucidated based on subjects viewpoints rather than on prior information. • ROL at the end of the study
Selecting sites and gaining entrée • Identify site consistent with research topic • For e.g.: health beliefs of urban poor, and inner city neighborhood with concentration of low income residents must be identified. • Involve in fieldwork
Developing an overall approach • Making broad design decisions, planning to go into the field • Emergent design- a design that emerges during the course of data collection • Do not always know in advance how the study will progress, how long. • Arrange for and test needed equipment- tape recorder, laptop., hiring or training interviewer, securing interpreter.
Addressing ethical issues More intimate nature of relationship
Activities in a Qualitative Study(cont’d) • Conducting the Study: Iterative Activities Making sampling decisions:Begin with subjects or observe few people who have first hand experience with the phenomenon. Allow for full range of beliefs, feelings and behaviors. Ongoing analysis and interpretation. • Collecting data • Evaluating trustworthiness • Analyzing data • Interpreting data
Data Analysis • Clustering together related types narrative information into coherent scheme. • Identify themes and categories. Gives rich description and theory of phenomenon • Ensure trustworthiness of data- actual viewpoints and experiences rather than perceptions
Activities in a Qualitative Study(cont’d) • Disseminating the Findings • Seeking publication outlets • Providing rich descriptions
