What do I believe? One study says to do one thing. Another study says that I should do the opposite!
Read the Study? Do you simply accept the findings because they are scientific? How do you know which studies are credible?

Phase 1 Selecting and defining the problem Review related literature Identify theoretical framework Propose research question and/or hypothesis
Phase 2 Choose research design Identify study population Design sampling plan Define how will variables be measured IRB approval
Phase 3 Data Collection - Recruiting - Obtaining informed consent - Collecting data
Phase 4 Data Analysis Interpret findings - Draw conclusions - Hypothesis is supported or rejected
Phase 5 Disseminate findings - May report findings in journal articles, oral presentations, or poster presentations Utilize findings - use in nursing practice
Sources of Research problems Experience and clinical fieldwork Nursing literature Social issues Theory Ideas from external sources
Development of research problems Selecting a topic Narrowing the topic Evaluating research problems Significance of the problem Researchability of the problem Feasibility of addressing the problem Time, Participants, Facility, Money,. Interest to the researcher
Statements of purpose Identify the population of interest Identify the independent variable Identify the dependent variable Experimental design: test the effectiveness of an intervention Non-experimental design: examine the relationship between two variables
Research Questions Existence of relationship Direction of relationship Strength of relationship Nature of relationship Moderated relationship Mediated relationship
Research Hypothesis Translate research questions into a precise prediction of expected outcomes State expected relationships between the independent variable and the dependent variable within a population Ha : μ1 μ2 귀무가설 (Null hypothesis) Ho : μ1 = μ2
연구주제의출처 간호연구주제의타당한출처는연구자의경험, 간호관계문헌, 이론을들수있다. 1) 연구자의실무 / 경험 연구자의매일의실무경험이나과거경험이연구문제 의좋은출처. 실무과정에서질문을다음과같이체계적 으로해보면연구문제를찾는데도움이될수있음
연구주제의출처 연구주제선정에도움이되는질문 질문의유형 이문제의양상은어떠할까? 이일은왜이렇게행해질까? 만일 면어떻게될까? 어떤접근이더효과적일까? 보다효과적인방법은없을까? 어떻게하면 를감소 ( 또는증가 ) 시킬수있을까? 질문의예 항암제투여후환자의피로감양상은어떠할까? 말기암환자의통증조절이왜충분히이루어지지않을까? 질분만환자의회음부불편감을완화시키기위해온요법대신냉요법을시행하면어떻게될까? 집단또는개별상담중어느것이알코올중독자에게더효과적일까? 정신과환자의저하된자존감을향상시키기위한더효과적인방법은없을까? 어떻게하면수술전환자의불안을줄일수있을까?
연구주제의출처 2) 간호관련문헌 (1) 관심영역에대한문헌을읽음으로써연구문제도출초보연구자 연구논문이실린간호저널을포함하여관심분야의잡지를정기적으로구독필요예 ) 대한간호학회지 (2) 같은문제에대해연구한선행논문을읽을때연구결과가일치하지않은경우, 연구결과와일상경험간에차이가있을때이를기초로연구문제도출 (3) 기존발표논문의제언부분에반복연구의필요성제시나앞으로필요한연구제시 (4) 대상자수가적거나동질적인집단일때다양한그룹의대상자에게반복연구의필요성제시
연구주제의출처 3) 이론 간호학과다른관련학문분야에서개발된이론 ( 불안이론, 통증이론, 건강행위이론 ) 에서연구문제도출 이론은현상에대한추상적이며일반화된설명으로서이론그자체는실제적문제나구체적상황을나타내지않는다. 그러므로이론으로부터연구문제를도출하기위해서는연역법을이용해야한다. 예 ) 건강신념모형 질병예방행위를이해하기위해제시된이론지각된민감성 예방행위이행잘함 이명제로부터유방암에대한지각된민감성은유방자가검진을유도할것인가? 하는연구문제연역이론으로부터연구문제도출전해당이론에대해충분한지식이있을것.
연구주제의평가 1) 연구문제의중요성 (Significance) (1) 연구결과가환자, 간호사, 지역사회에유용한지식이될것인지 (2) 연구결과가실무에적용될수있을것인지 (3) 이론적인타당성이있을것인지확인 2) 연구가능성 (Researchability) 철학적질문, 도덕적, 윤리성속성의문제는과학적방법으로연구될 수없음
연구주제의평가 3) 연구수행가능성 (Feasibility) 연구가현실적으로수행할수있는여건을갖추었는지를고려함. (1) 시간 : 연구하기에충분한시간확보 (2) 대상자의이용가능성 : 연구에참여할대상자를일정시간내에충분히확보 (3) 관련기관의협조 : 연구수행기관의승인이필요 (4) 시설기구 : 연구를수행하기위한적절한공간, 기구, 시설등의이용가능 (5) 비용 : 연구문제는예상범위내에서제안되어야함 (6) 연구자의경험 : 연구문제는연구자의과거지식이나경험이있는분야에서선택가능, 자료수집과분석에필요한기술필요 (7) 윤리적고려 : 참여할대상자에게부담하거나비윤리적요구, 권리를침해해서는안됨.
연구목적의진술 연구주제에대한평가가이루어진후연구자는연구할현상을다른사람과의사소통하기위해연구문제진술 연구목적진술은연구할영역을명시하는진술로서주요연구변수, 연구변수간의가능한관계, 연구대상자의특성규명 연구목적의좋은진술은연구설계과정에지침제공 연구목적을 2 가지형식으로진술 연구주제진술의예 의문문형식 ( 연구문제 ) 서술문형식 ( 연구목적 ) 진술형식 의문형 서술형 주제진술의예 간호사의간호업무수행능력은무엇인가? 간호사의성격유형과리더십과는관련이있는가? 호흡재활프로그램이만성폐쇄성폐질환자의산소포화도를증가시키는가? 본연구의목적은간호사의간호업무수행능력을규명하는것이다. 본연구의목적은간호사의성격유형과리더십사이에유의한관계가있는지를규명하는것이다. 본연구의목적은호흡재활프로그램에참여한만성폐쇄성폐질환환자에서산소포화도가증가되는지를검증하기위함이다.

Theoretical Framework Theory Abstract generalization that explains how phenomena interrelate and is based on prior science ( 현상의추상적법칙체계 ) Purpose of theoretical framework - Link the study to a larger body of knowledge already established ( 연구를검증된지식체계와연결 ) - Test a theoretical model KYUNG HEE UNIVERSITY 42
Conceptual Frameworks Concepts: abstract ideas The ideas are linked but may not be in a logical method until more testing of the model is done KYUNG HEE UNIVERSITY 43
