itle and topic
Concise and descriptive.
Stated in terms of a functional relationship
indicating the independent and dependent
variables.
If possible, think of an informative but catchy title
that wins the reader's interest.
7. II- Introduction
The introduction typically begins with
A. a general statement of the problem area, with
B. a focus on a specific research problem, to be
followed by
C. the rationale or justification for the proposed
study.
8. The introduction generally covers the following
elements:
State the research problem.
Provide context and set stage for research
question (show its necessity and
importance).
Present the rationale of study and clearly
indicate why it is worth doing.
Describe major issues and sub-problems to
be addressed by your research.
9. Identify the key independent and
dependent variables.
State your hypothesis, if any.
10. Structure of The introduction section
A good introduction has the following elements:
(a)
(b)
(c)
(d)
(e)
a general description and the background of the problem to be
researched;
relevant factors influencing the research problem;
the state of knowledge relevant to the research problem as given in
the literature;
the relevance of your own research;
a problem definition or research question and, if applicable, the
expected outcome or hypotheses.
The order in which to include these elements is not fixed, particularly the
order of elements b through d. If you use new concepts that are not
generally known, you must explain them.

12. I Saudi A
n
rabia, re liable studie s that tackle the pre vale nce and patte rn o f
re fractive e rro rs amo ng primary scho o l childre n are scarce , with varied results
due to inconsistency in the cutoff used for errors definition form 23% in the high
altitude Abha city (Abolfotouh et al.,1993) to 10.7% among pre-school children in
Jeddah city at sea level (Wedad et al., 2002). Moreover, the Saudi
school health services provided by Ministry of Education do not include adequate
vision screening facilities (Wedad et al., 2002). In accordance with WHO’ s global
initiative “ Vision 2020” The right to sight
(http://www.vision2020.org/main.cfm?type=WHATVISION2020), a professional
based (optometry) screening program for all school-aged children is recommended
to provide an early detection and initiate early treatment.
The objective of the this study was determine the prevalence and pattern of
refractive errors among primary school children in the age group of 6-14 years of
both sexes in Al Hassa, Eastern Province, Saudi Arabia.
13. To address the existing gap in the literature on smoking among adolescents we have
tested the following hypotheses: First, o lde r male ado le sce nts are mo re like ly to
smo ke to bacco than yo ung e r and fe male ado le sce nts. Se co nd, smo king amo ng clo se
re lative s (e nviro nme ntal to bacco e xpo sure ) and frie nds (pe e r pre ssure ) wo uld
incre ase the like liho o d (risk) o f be ing curre nt smo ke r. Finally, ce rtain
mo tive s (so cializing , imitatio n, o uting , rathe r than re lie ve o f stre ss and ple asure ) and
the pre se nce o f de pre ssive and/o r anxie ty diso rde rs may re pre se nt po te ntial
pre dicto rs fo r the curre nt smo king status amo ng ado le sce nts. To the best of the
authors’ knowledge, there are no previous studies in Saudi Arabia that address the
psychosocial predictors of smoking status among this age group. In this study, we
attempted to provide baseline information on the psychosocial determinants
and prevalence of smoking among adolescents in secondary schools in Al Hassa,
KSA, for proper design of practical and effective intervention strategy.
15. L
iterature review (functions)
Ensures that you are not "reinventing the wheel".
Gives credits to those who have laid the groundwork.
Demonstrates your knowledge of the research problem.
Demonstrates your understanding of the theoretical and
research issues related.
Shows your ability to critically evaluate relevant
literature information.
Indicates your ability to integrate and synthesize the
existing literature.
Convincing that proposed research will make a
significant and substantial contribution to the literature.
16. In Saudi Arabia there has been a considerable change in the pattern of
breastfeeding in recent decades due to population transition as a result of
advancements in socioeconomic status.7 Breastfeeding in Saudi Arabia has
been customary;8 its duration used to exceed the age of 24 months, and solid
food would be introduced as late as 12–18 months and complementary to
breastfeeding.9 Studies from Saudi Arabia have recorded a progressive
decline in breastfeeding practice and duration, especially among young
mothers in urban areas,10–12 with early introduction of bottle feeding12,13 and
earlier introduction of solid foods.14
The initiation and duration of breastfeeding depend on several determinants, namely,
socio-demographic, psychosocial, biomedical, and healthcare-related factors,
community attributes, and public policy;15 however, the importance of these factors
varies across countries and over time. Few studies14–16 have addressed factors related
to initiation and exclusivity of breastfeeding in Saudi Arabia with inherent faults
either in samples studied of purely urban mothers14 or using different cutoffs for
exclusive breastfeeding.16
17. Your research competence will be questioned if
any of the below applies to your proposal.
Lacking organization and structure
Lacking focus,
unity and coherence
Being repetitive and verbose
Failing to cite influential papers
Failing to keep up with recent developments
Failing to critically evaluate cited papers
Citing irrelevant or trivial references
18. Organize your literature review
Subheadings to bring order
and coherence.
Keep in mind that you are telling a story.
19. V-Methods:
Tells how you plan to tackle the research problem.
Describe the activities necessary for the completion of your
project.
Contains sufficient information for the reader to determine
whether the methodology is sound.
Should contain sufficient details for another qualified
researcher to implement the study.
Demonstrates that “ your approach is the most appropriate and
most valid” .
20. Instructions for writing the Method section
Methodological
elements are described precisely
and accurately.
Unlike the Introduction, the Method section is
divided into subsections. Each methodological
element is described in a separate subsection with
its own heading.
21. Ele me nts o f the M tho d Se ctio n

the design - the 'format' - of the study.

35. Summary: For quantitative studies, the method section
typically consists:
Design: What kind of design do you choose?
Subjects or participants:
Who will take part in your study ?
What kind of sampling procedure do you use?
Instruments:
What kind of measuring instruments do you use?
Why do you choose them?
Are they valid and reliable?
Procedure:
How do you plan to carry out your study?
What activities are involved?
How long will it take?
36. VI- Statistical analysis
Data analysis was carried out using SPSS 16.0 (SPSS Inc, Chicago, IL, U.S.A).
For categorical data, frequency, proportions and percentage were used for
reporting, Chi square, Z test and Chi square for trend were used for
comparison.
Major osteoporotic and hip fractures probabilities were reported using the mean
percentage and the range. For continuous data mean, standard deviation, and
median were used to express the results, t-test and Mann Whitney test were
used for comparison.
Multivariate logistic regression model was generated to determine the possible
predictors for receiving osteoporosis screening (BMD) (dependent variable) by
inclusion of significant potential independent variables revealed form
univariate analysis. Logistic regression analysis was carried out for the subset
of population including only women and men aged ≥ 60 (individuals for whom
screening is recommended).
P value of ≤ 0.05 was considered significant.

37. VII- Results:
Obviously
you do not have results at the proposal
stage.
However, you need to have some idea about what
kind of data will be collected, and what statistical
procedures will be used to answer your research
question or test you hypothesis.
38. VIII- Discussion:
