Starting the Research Process
Formulating a specific, applicable research problem statement is an important step in beginning a research process. The problem statement defines the focus of the research study, dictates what methods and tools will be used, and sets the stage for all subsequent elements of the research process. Because of this, it is necessary to put a great deal of thought into the problem statement to ensure that the rest of the research process will be well planned and appropriate to the problem at hand.
This week’s Discussion asks you to identify evidence-based practice problems that can be addressed using quantitative research methods. Based on the practice problem you select, formulate a quantitative research problem statement. In this Discussion, you are also given the opportunity to evaluate your colleagues’ problem statements. Please refer to this week’s Learning Resources for appropriate and scholarly examples of research problem statements and how they inform the rest of the research process.
To prepare:
Determine a nursing practice problem that is of interest to you and that is appropriate for a quantitative research study.
Note:
You will continue to use this problem in the Discussions over the next several weeks.
Using the Walden Library and other credible sources, locate and read two or three articles that address your practice problem.
(you must cite the articles read in this assignment)
With your practice problem in mind, review the Learning Resources and media presentations focusing on the strategies presented for generating a research problem statement.
Ask yourself: What is the importance of my practice problem to nursing, research, and theory? How might addressing this problem bring about positive social change? How will investigating this problem support evidence-based practice?
By Tomorrow 09/06/17, write a minimum of 550 words in APA format with a minimum of 3 references from the list below which include the level one headings as numbered below:

Research problem is a question that a researcher wants to answer or a problem that a researcher wants to solve. Identification and formulation of a research problem is the first step of the research process.
However, it is considered as one of the most challenging and difficult phases of any research project. It is believed that selection of a good research problem is a discovery in itself.
Selection of a research problem depends on several factors, such as researcher's knowledge, skills, interest, expertise, motivation, and creativity with respect to the subject of inquiry.
In addition, a researcher needs to ensure that a selected problem has high significance and implication for his or her profession as well as it should be a suitable, feasible, testable, and solvable research problem.
It is believed that most of the good research studies need lots of time for selection of a research problem. Initially, every researcher faces the predicament of identifying, selecting, and formulating a good research problem. This chapter will answer these pertinent questions.
On completing this chapter, you will be able to:
Describe why research is important in the nursing profession and discuss the need for evidence-based practice
Describe historic trends and future directions in nursing research
Describe alternative sources of evidence for nursing practice
Describe major characteristics of the positivist and naturalistic paradigm, and discuss
similarities and differences between the traditional scientific method (quantitative research) and naturalistic methods (qualitative research)
Identify several purposes of qualitative and quantitative research
Selection of the Problem pg 13One of the most difficult tasks co.docxbagotjesusa
Selection of the Problem pg 13
One of the most difficult tasks confronting the beginner is to select a researchable problem. More often than not, the newcomer has a proclivity to tackle an exotic issue, thus making the problem either too broad or too narrow in scope. Some factors that should be involved in the ultimate selection are listed here (Bailey, 1994):
1. Interest: The researcher should be interested in pursuing the problem area. The problem should be related to the background and career interests of the student, and in pursuing the problem the student should develop useful skills for the future.
2. Operability: The nature of the problem should be such that the researcher has both the resources and the time available to complete the subject.
3. Scope: While the research problem should not attempt to solve all the health dilemmas of the world, neither should it be so small as to negate the variables necessary for adequate results.
4. Theoretical and practical values: The research should contribute to the health field, perhaps through publication, and be of benefit to health practitioners.
5. Health paradigm: This is the school of thought or model employed by the researcher as discussed in an earlier chapter (Chapter 1).
6. Values of the researcher: The myth of value-free research is just that, a myth. The student of research should be aware that in addition to being unstable, values may prejudice the research effort to the degree that all objectivity is lost. Note that even the selection of a problem is value-laden.
7. Research methodology: Every researcher has a philosophy of research that affects procedure. Thus, the student must be certain that hypotheses are well written and that appropriate criteria are used to interpret the data to reach conclusions.
8. Reactivity: The method of data collection should be scrutinized for reactivity. That is, a reactive technique brings about a reaction on the part of those being studied in a way that affects that data. The reactive effect is commonly labeled the “Hawthorne effect” from the study of the Hawthorne Plant of the Western Electric Company in Chicago, where it was found that worker productivity increased simply because the personnel were being observed.
9. Unit of analysis: In health research, the unit of analysis may be an individual (such as the health habits of a single anorexic patient) or an entire population (patterns among the hospital anorexic population). The researcher must ascertain which is most appropriate and whether resources are available to collect data.
10. Time frame: This is particularly important to the student because only a limited amount of time is usually available. In a cross-sectional study aparticular population is involved at a single point in time; in a longitudinal time frame, data are gathered over an extended period of time (such as months or years).
11. Budget: To ensure that your proposal is feasible, write up a budget for expensive items. These items m.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

1.How to choose a research topic
10. Answering the question "What"
•1. phenomena: what is to be study??
• smoking,depression,lung cancer,roles of home management of
diarrhea,anti-tetanus vaccination.
2. .the situation: what we want to know about the phenomena??
•EX:prevalnce,proportion,incidence,effects,outcome,cause,outcome,
•risk factors,relationship,coverage.
11. Examples:
1.Awareness and usage of sign language among doctors in main
khartoum hospitals(ibrahim malik,bahri,omdurman)teaching hospitals
october 2017
2.knowledge and attitude of pregnant ladies toward antitetanus vaccine
In bahri teaching hospital april 2018.
3. The role of vitamins in prevention of diabetes complications in
diabetic patients attend jabir abu-elizz clinic march 2019
12.
13. - students in om dowan ban khalwa observed to have alot of cases of
diarrhea.
- smoking among medical female are found to be high.
- workers in X factory develop chest problem.
- the marks of students in mid semester exam are far less than in the
final semester exam.
- mother knowledge about home mangement of diarrheal disease
Formulate your research title:
15. •diabetic patients who take a multivitamins supplementation are
found to have much less complications comparing with those pts who
did not,but the exact role of the vitamins is not yet establish , so we
want to Know the exact cause that reduce the complication.
16. - Studies show that diabetic patients who take
the multivitamines have minimum
complication ( rationale of the study ).
- Role of vitamins in reducing the
complication (gap of knowledge)
- what is the exact cause that reduce the
complication? (the question)
17. 4.Research objectives:
Øgeneral objectives:(main objectives)
Østatement of the main associations and relationships that
you seek to discover or establish
To+ action oriented- verb.+ your main objecrive of the study (find it in the title.
Øspecific objectives:(sub-objectives)
Øspecific aspectsof the topic that you want to
investigate within the main framework of your study.
Øsubdivided your main objective into subobjectives .
Also To + action oriented- verb + the sub-objective.
ØExamples of action oriented verbs: to determine’, ‘to find out’, ‘to
ascertain’, ‘to measure’ and ‘to explore
21. Suppose you want to do a research in the
following ideas what is your specific objectives :
Asthma
Cervical cancer
Diabetes
Neural tube defects
22. 5.Introduction:
It is the background of your research study , Start with a very
broad perspective of the main subjectarea, before
gradually narrowing the focus to the central
problem under investigation.
You must cover the following points in order to write informative and
useful introduction :
- Overview.
-Historical background ( if found ).
- prevlance and a language of numbers.
- main issues related to the study area ( causes, etiology..etc)
- the central problem.
- finding related to the central area (previous studies)
23. Example:
awareness about Basic life support in final year medical
student at college of medicine-Elneelain university march 2020
Basic life support (BLS) is a level of medical care which is used for victims of life-threatening illnesses
or injuries until they can be given full medical care at a hospital(overview).
The International Liaison Committee on Resuscitation (ILCOR) was formed in 1992 to
coordinates the efforts of resuscitation worldwide , In 2000, the committee published the first
resuscitation guideline. In 2005, the committee publishes International Consensus on
Cardiopulmonary resuscitation (CPR) and Emergency Cardiovascular Care (ECC) Science
with Treatment Recommendations. Since 2010, the committee provided materials for
regional resuscitation providers such as European Resuscitation Council and American
Heart Association to write their own guidelines(history).
BLS component include the chest compressions, mouth to mouth breathing and AED (issue
related to the study area)
24. Doctors must be well qualified and must know all the BLS principles, medical
students specifically final year medical student are highly recommended to be
included in training programs, as they will soon will facing the practical life (central
problem)
• a study aim to evaluate the awareness of medical student in dundee 2005 they
found that 55% are found to know the mean of the abbreviation, 60% know the
rate number of chest compression , 30 know how to perform mouth to mouth
breathing, and they conclude that final year medical students have good idea
about the BLS(main finding or previous studies)
26. • You want to investigate the following ideas what is the
main points you may want to write in the introduction?
• - Die of asthmatic patients in young ages.
• - awareness of diabetic patients about the importance of get a wound care.
• - effects of screening of cervical cancer on the good prognosis.
• - spina bifida in mother not taking the folic acid.
27. •6.Litreature review:
• Important responsibility of the research is to compare your finding o those of others.
• Functions of the literature review:
focus to your researchproblem.
broaden your knowledge base .
It provides a theoretical background to your study.
It helps you establish the links betweenwhat you are proposing to examine and
what has already been studied.
It enables you to show how your findings have contributed to the existing body knowledge
in your profession.
It helps you to integrate your research findings into the existing body of knowledge.
33. Methodology:
Research methodology is the specific procedures or techniques used to
identify, select, process, and analyze information about a topic. In a
research paper, the methodology section allows the reader to critically
evaluate a study's overall validity and reliability.
34. Elements should be included in the
research methodology part:
study design.
study area/setting
study population.
study variables.
data collection technique.
data collection tool.
sampling technique.
sample size
35. 7.Identify the variables:
• Perception or concept that can be measured and can take different values.
• Examples: gender,level of education...etc.
• Types :1. from view of relationship:
• Independent: suppose responsible for the change.(smoking).
• Dependent : outcome caused by the independent variable(cancer).
• Extraneous : factors that increase or decrease the magnitude between the
independent and dependent variables( number of cigarettes or
the amountof tobacco smokedevery day; the duration of
smoking; the age of the smoke)
• intervening : link the independent and dependent variables (In certain situations
the relationship between an independent and a
dependent variable cannot be established withoutthe
intervention of another variable).
36.
37.
38. • 2.from view of study design : mainly in experimental or controlled studies:
• Active : the variable can be changed or controlled.( teaching models)
• Attribute : can not be changed or controlled.(student age , gender ,...etc)
39.
40. • 3.View of unit of measurement:
• Could be measure in numbers?: quantitative.
• Possibility of fractions(measurement of weight 3.5)>continous quantitative variable
• No possibility of fractions (number of people)discrete quantitative variable
• Could not measure in numbers>qualitative.
• Could be logically arranged? (stage of cancer,level of education?ordinal qualtitative
variable
• Could not logically arranged>(colours) nominal qualitative variable.
• option of variation more than two? Non-numerical nominal qualitative variable (Race)
• Option of variation only two:binary nominal qualitative variable.(gender)
41.
42. Who is going to answer these???!
• Which type of variable is this (in unit measurement sense):
• Diagnosis of a disease , tribe, height, countries in the wourld , a state of employment.
• identify the dependent,independent , extraneous and intervening variables:
• junk food and obesity.
• alcohol consumption , number of cups per day , amount , duration of being alcoholic
consumer ,liver cirrhosis, drinking alcohol.
Identify the active and attribute variables :
In a study the researcher want to know the association between root of drug administration
and the toxicity of the 5-FU Chemotherapy .
44. Cross-section study
(Descriptive)
- obtaining an overall ‘picture’.
-findingout the prevalence of a phenomenon, situation, problem,
attitude or issue,
- only one contact with the study population,
Ex:
1.The incidence of HIV-positive cases in Australia.
2.The reasons for homelessnessamong young people.
45. Case-control study
we are searching for the risk factor.
retrospective.
Outcome
Risk factor
51. 9.Sampling:
• important terminologies:
• Target population:
• The whole population targeted by the study.
• Study population:
• Part of the target population either more affected by the phenomena or better reflecting its characteristics.
Ex:assessment of nutritional anemia in pregnant ladies.
• Sample :
• Part of the target population and study population , the information is collecting from them.
52.
53. • Sampling methods (techniques):
• 1.probability sampling method:
• When we have the total number of individuals comprising the target
population.
• Types:
• 1.simple random sampling.
• 2.systemic random sampling.
• 3.cluster sampling.
54. 1.simple random sampling method:
we select the samples (study units) from the target population randomly.
2.systemic random sampling :
We select the first sample from the target population randomly and select the
others by specific system.
3.cluster sampling method :
We select aggregates of study unit from a list of aggregates presented as
geographical area rather than individuals.
55.
56. 2.Non-probability sampling methods:
When we can not estimate the total number of the total population.
1.convenience sampling.
2.snow-ball sampling.
1.convenience sampling:
The target population is expected to come into certain place.(clinic).
2.snow-ball sampling method:
The target population are not expected to come to certain place but the
researcher look for the first sample and through this sample can find the
rest of the samples.(addicts).
57.
58. Sample size:
• how many sample i need in order to make the samples more
representable to the target population.
• Sample size in qualitative research:
• in qualitative research, as the main focus is to
explore or describe a situation, issue, process
or phenomenon, the question of sample
size is less important. You usually collect data
till you think you have reached saturation point in
terms of discovering new information.
59. Sample size in qualitative research:
Sample size = n )
÷ 1+n×e2)
N=total number
E= 0.05
60.
61. Calculate the sample size for the following:
• how many doctors we need from 500 doctor to represent the doctors
in an intrnational conference.
• how many students we need from 120 student to gather their
opnions about the teaching staff??
• how many lady we need to know the number of mothers vaccinated
againest tetanus during the pregnancy in an outpatient clinic.
• how can we calculate the sample size for 40 women to determine
their information about the risk factors of breast cancer??
62. Data collection tools:
The instruments used to collect data.
Questionnaire:
Sets of questions used to measure the variables.
Interview:
The interviewer read the questions to the respondent then record their
answers.
63. Elements should be included in the
research methodology part:
study design.
study area.
study population.
study variables.
data collection technique.
data collection tool.
sampling technique.
sample size.
64. 10.Analysis of Data:
review and check data for problems concerning the source of data,coverage of the
variables , and consistency of the registered data.
Use can analyze your data manually or using a computer program (SPPS).
65.
66. 11.Discussion
•after you get your results try to copare it with the other same
studies
findings.
Always remember:
Discussion is not to translate your results into word !!
67. 12. Conclusion:
At the end of your research you must tell us the answer of your
question/s or the solve of your problem.
