Whether a problem situation requires research depends on threeIdentification of Topic

Whether a problem situation requires research depends on three conditions:

1 There should be a perceived differenceperceived difference or1. There should be a perceived difference perceived difference or discrepancy between what exists and the ideal or planned situation;

ll2. The reason(s) for this difference should be unclearunclear (so that it makes sense to develop research questions); and

3 There should be more than onemore than one possible answer to a3. There should be more than one more than one possible answer to a question or more than one solution to the problem.

Criteria for Prioritizing Problems for Research• Relevance • Avoidance of duplication

U f d t d d (ti li )• Urgency of data needed (timeliness) • Political acceptability of study

F ibilit f t d• Feasibility of study • Applicability of results • Ethical acceptability

Page 9: Research Methodology 002

RelevanceThe topic you choose should be a priority problem Questions to beThe topic you choose should be a priority problem. Questions to be asked include:• How large or widespread is the problem? o a ge o desp ead s e p ob e• Who is affected? • How severe is the problem?How severe is the problem?

If you do not consider a topic relevant, it is not worthwhile to continue rating it. In that case you should drop it from your list.

Page 10: Research Methodology 002

Avoidance of DuplicationBefore you decide to carry out a study it is important that you findBefore you decide to carry out a study, it is important that you find out whether the suggested topic has been investigated investigated beforebefore either within the proposed study area or in another areabeforebefore, either within the proposed study area or in another area with similar conditions.

consider carefully whether you can find answers to the problem in already available, unpublished information or just by using your common sense. If so, you should drop the topic from your list.

Page 11: Research Methodology 002

Urgency of Data Needed (Timeliness)tltlHow urgentlyurgently are the results needed for making a decision or

developing interventions at various levels (from community to policy)? p y)Consider which research should be done first and which can be done later.

Page 12: Research Methodology 002

Political Acceptabilityi t ti t tIn general it is advisable to research a topic that has the interest interest

and support of the local/national authorities. This will increase the chance that the results of the study will be yimplemented.

Page 13: Research Methodology 002

FeasibilityLook at the project you are proposing and consider theLook at the project you are proposing and consider the complexity complexity of the problem and the resourcesresources you will require carrying out your study. q y g y yThought should be given first to manpower, time, equipment and money that are locally available.

Page 14: Research Methodology 002

Applicability of Possible Results/RecommendationsIs it likely that the recommendations from the study will be applied?Is it likely that the recommendations from the study will be applied?

This will depend not only on the managementmanagement capability within p y gg p ythe team and the blessingblessing of the authorities but also on the availability of resourcesresources for implementing the recommendations.

Likewise, the opinion of the potential clients and of responsible staff will influence the implementation of recommendations.will influence the implementation of recommendations.

Page 15: Research Methodology 002

Ethical AcceptabilityWe should always consider the possibility that we may inflict harm on others whileWe should always consider the possibility that we may inflict harm on others while carrying out research. Therefore, review the study you are proposing and consider important ethical issues such as:

1. How acceptable is the research to those who will be studied? (Cultural sensitivity must be given careful consideration).

2 Can informed consent be obtained from the research subjects?2. Can informed consent be obtained from the research subjects? 3. Will the condition of the subjects be taken into account? For

example, if individuals are identified during the study who require certain services, will these be given? What if this interferes with your study results?will these be given? What if this interferes with your study results?

4. Will the results be shared with those who are being studied? Will the results be helpful in improving the lives of those studied?studied?

Deciding on the Focus and Scope of the ResearchSeveral issues are particularly important to consider including:Several issues are particularly important to consider, including:

1. Usefulness of the information. Would the information that will be collected on this problem help solve the problem? Who

ld th fi di l t d t th f t i th diwould use the findings related to the factors in the diagram that would be studied? How would the findings be used?

2. Feasibility. Is it feasible to analyze all the factors related to y ythe problem in the time frame available for research?

3. Duplication. Is some of the information related to factors in the diagram already available? What aspects of the problemthe diagram already available? What aspects of the problem need further research?

Formulating the Problem StatementThe first major section in a research proposal is the ‘statement of the problem’.j p p p

Why is it important to state and define the problem well?Why is it important to state and define the problem well?Because you will find that a clear statement of the problem:y p

• Is the foundation for the further development of the research proposal (research objectives, methodology, work plan, budget, etc.).

• Makes it easier to find information and reports of similar studies from pwhich your own study design can benefit.

• Enables you to systematically point out whywhy the proposed research on the problem should be undertaken and whatwhat you hope to achieve with the study resultsthe study results.

This is important to highlight when you present your project to community members, relevant ministries and donor agencies who need to support your study or give their g pp y y gconsent.
