Scientific Writing Using the IMRaD Model: A Practical Guide for Researchers

Ali Hmidoush — Mon, 02 Mar 2026 11:12:05 +0000

Overview

Scientific writing and publishing form the heart of medical research. A well-written paper not only shares data but also tells a story of discovery.

Most journals follow a standard format known as IMRaD — Introduction, Methods, Results, and Discussion.

Scientific Writing Using the IMRaD Model is a structured approach that forms the foundation of modern medical research, and is widely used as a standard framework for presenting studies in a clear and organized manner. Understanding this structure helps young researchers organize ideas clearly and meet publication standards

The IMRaD Format: Your Paper’s Backbone

Scientific writing using the IMRaD model guides the reader step by step through the research: What is the topic? How was the study conducted? What are the findings? And what do these findings mean within the context of current scientific knowledge?

Each of these sections will be discussed in detail.

Section	Question Answered	Purpose
Introduction	Why was the study done?	Provides context and sets the objective.
Methods	How was it done?	Describes how the study was conducted.
Results	What was found?	Presents findings objectively.
Discussion	What do the results mean?	Interprets and relates them to previous work.

Writing a Compelling Title and Abstract

Your title and abstract are the first impression editors and readers get, and often decide whether your paper is read or ignored. Therefore, crafting these elements with precision and professionalism is a critical step in the scientific publishing process.

The Title

The title is the first element visible in search engines and academic journals. It should be direct, concise, informative, and search-friendly. Its purpose is to convey the main idea of the research without ambiguity or exaggeration, while ensuring discoverability in electronic searches.

The Abstract

General Tips for Writing an Effective Title:

Use clear keywords that accurately reflect the study topic.
Make the title descriptive rather than general; avoid vague titles such as “A Study on Cancer”.
Ideally, the title should consist of 8–15 words, though some journals allow up to 20 words, especially in clinical articles—for example: “The Association Between Smoking Habits and Lung Cancer Incidence Among Young Adults in Urban Areas.”
Do not include study results in the title.
Include the main variable, population, and the study design when relevant, such as Cross-sectional Study or Randomized Controlled Trial.

Example:

“A study of diabetes”

“Glycemic control among type 2 diabetes patients attending primary care clinics in Amman: a cross-sectional study.”

The abstract is the most frequently read section of a research paper. Its purpose is to provide a concise and comprehensive overview of the study’s objectives, methodology, results, and key conclusions, allowing readers to assess the relevance and significance of the research before reading the full paper

Typical Structure of a Scientific Abstract:

Background: A brief overview of the problem or phenomenon under investigation.
Objective: The aim or research question the study seeks to address.
Methods: The study type, sample, instruments, and data analysis approach.
Results: A concise presentation of the main statistical or numerical findings.
Conclusion: Interpretation of the results and their significance.

Example:

Lung cancer is among the most prevalent types of cancer worldwide, with smoking being the primary risk factor. This study aimed to analyze the relationship between smoking and lung cancer risk in adults. A cross-sectional study was conducted with 500 participants, collecting data via questionnaires and medical record analysis. Results indicated that smokers had a threefold higher risk of developing lung cancer compared to non-smokers. These findings highlight the importance of strengthening smoking cessation awareness programs as an effective preventive measure against lung cancer.

General Tips for Writing an Abstract:

Write the abstract after completing the full study to ensure accuracy.
Use formal and clear language without personal opinions or emotional expressions.
Avoid including references, tables, or figures in the abstract.
Adhere to the word limit specified by the publisher (typically 150–250 words).
Ensure that every piece of information in the abstract is present in the main text of the paper.

The Introduction

The introduction of any scientific paper aims to convince the reader that the study is necessary and addresses a genuine knowledge gap. It prepares the reader to understand why the research was conducted, not just what was investigated. The introduction should be brief (3–5 paragraphs), and is typically presented in a sequential and logical manner, covering:

The introduction can be likened to a funnel, starting from a broad concept and gradually narrowing down to the specific research objective.

Within this framework, scientific writing using the IMRaD model provides a logical structure that helps researchers present the background, define the knowledge gap, and clearly state the objective and hypothesis.

Background

This section provides an overview of the importance, prevalence, and health, social, or economic impact of the topic. It should include recent statistical data and references from reliable scientific sources to support the presented information.

Knowledge Gap

This paragraph highlights what previous studies have not addressed or what remains unknown. It can reference prior research and then identify areas of deficiency or uncertainty.

The introduction typically concludes with a clear statement of the study’s purpose or main hypothesis, preferably in a direct and precise sentence.

Objective and Hypothesis

The objective and hypothesis are essential elements of any scientific study, guiding the research from inception to conclusion. Without a clear objective and defined hypothesis, a study loses direction and cannot have its results evaluated scientifically.

The Objective

The objective is the primary purpose of the study—what the researcher aims to understand or achieve. It serves as the starting point that determines the type of data to be collected and the analytical approach. A well-defined objective should be:

The Hypothesis

The hypothesis is a scientific prediction based on existing knowledge about what the study’s results might reveal. It is a logical assumption grounded in available evidence and theories, which the researcher aims to test through the study. A valid hypothesis should be:

Testable: Can be evaluated through data collection and analysis.
Scientifically grounded: Based on evidence and reasoning, not mere opinion.
Falsifiable: Can be proven true or false through the study’s results.

Relationship Between Objective and Hypothesis

The objective and hypothesis are logically connected:

The objective defines what is being investigated.
The hypothesis predicts what is expected to be discovered.

The objective provides the overall framework, while the hypothesis offers a specific, testable application within that framework. Once clearly formulated, they facilitate the development of the Methods section and the selection of appropriate tools and analyses.

The Methods

The Methods section describes how the study was conducted so that any other researcher can reproduce it and verify the results “Reproducibility”. The researcher should provide a clear and precise description of all steps and procedures, avoiding vague or incomplete details. This section is among the most technical and organized parts of a scientific paper and should be written in past tense, as the events have already been completed.

This level of clarity and transparency is essential in scientific writing using the IMRaD model, allowing other researchers to evaluate and reproduce the study reliably.

Main Components:

This section is usually organized into subsections including:

Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL): A Full Guide for Researchers and Clinicians

Ali Hmidoush — Mon, 21 Jul 2025 21:41:36 +0000

Introduction

Chronic Urticaria (CU) is more than just a skin condition; its persistent itching (pruritus) and appearance of wheals and angioedema can significantly degrade an individual’s quality of life (QoL). For researchers and clinicians dedicated to understanding and mitigating the impact of CU, a robust and specific measurement tool is essential.

The Chronic Urticaria Quality of Life Questionnaire, often abbreviated as CU-QoL or CU-Q2oL, stands out as a pivotal instrument in this domain. Developed to specifically assess QoL impairment in patients suffering from chronic hives, the CU-Q2oL provides critical insights that can inform both clinical practice and research endeavors. This article offers an in-depth exploration of the CU-Q2oL, detailing its features, structure, applications, and psychometric properties, tailored for experts in dermatology, allergy, and patient-reported outcomes.

Key Features of the Chronic Urticaria Quality of Life Questionnaire

Purpose and Use

The primary purpose of the CU-Q2oL is to assess the quality of life impairment experienced by patients with chronic urticaria. This specialized focus allows for a nuanced understanding that generic QoL instruments might miss. It translates the subjective experiences of CU patients into quantifiable data, enabling researchers to track disease burden, evaluate treatment efficacy, and identify areas of patient life most affected by the condition. For clinicians, the CU-Q2oL can be instrumental in tailoring management plans and monitoring patient progress beyond just symptom counts. The questionnaire is designed to capture the multifaceted impact of CU, moving beyond purely physical symptoms to encompass emotional and functional well-being.

Target Population

The CU-Q2oL is specifically designed for adult patients aged 18 years and older who are diagnosed with chronic urticaria. This includes:

Young Adults (18-24 years)
Middle-Aged Adults (25-44 years)
Older Adults (45-64 years)
Seniors (65+ years)

While the questionnaire focuses on adults, its relevance spans across these various adult age groups, making it a versatile tool for a broad spectrum of the patient population suffering from chronic urticaria.

Structure

The CU-Q2oL is a 23-item questionnaire that comprehensively assesses the impact of chronic urticaria across six dimensions:

Pruritus (2 items): Focuses on itching and the presence of wheals.
Swelling (2 items): Addresses swelling around the eyes and lips.
Impact on Life Activities (6 items): Examines how urticaria affects work, sleep, physical activity, leisure, social life, and eating habits.
Sleep Problems (5 items): Covers difficulties falling asleep, nighttime awakenings, fatigue, poor concentration, and sleep-related nervousness.
Limits (3 items): Assesses mood disturbances, food restrictions, and limitations in physical activities.
Looks (5 items): Highlights concerns about visible symptoms, embarrassment, cosmetic use, clothing choices, and appearance-related medication side effects.

This structured format ensures a holistic and patient-centered evaluation of chronic urticaria’s impact.

Scoring Method

The CU-Q2oL employs a 5-point Likert scale for its 23 items, with responses ranging from 1 (“not at all”) to 5 (“very much”). The scoring process involves summing the raw scores from all items. This total summed raw score is then transformed to a scale ranging from 0 to 100. Importantly, on this transformed scale, higher scores indicate a worse quality of life. This scoring system allows for a standardized assessment of QoL impairment. Researchers and clinicians can also analyze scores for the individual six dimensions to gain more granular insights into specific areas of concern (pruritus, swelling, life activities, sleep problems, limits, and looks). Currently, specific cut-off scores for distinct levels of severity (e.g., mild, moderate, severe QoL impairment) are not explicitly detailed in the provided information.

Administration Format

The CU-Q2oL offers flexibility in administration via:

Paper-based forms
Digital (Online) platforms
Interviews (In-person)
Phone/Video Call

No special training is necessary to administer or interpret the CU-Q2oL, as it is self-administered and easily managed by healthcare staff. Administration is typically quick, estimated at 5 to 10 minutes.

Applications of the Chronic Urticaria Quality of Life Questionnaire

The AQOL demonstrates significant utility across various clinical and research settings. For instance, in clinical practice, healthcare providers can use the AQOL for:

Screening: Identifying patients for the extent of QoL impairment at diagnosis.
Monitoring: The questionnaire is valuable for monitoring changes in QoL over time, in response to treatment, or as the disease fluctuates.
Treatment Planning: Insights from the CU-Q2oL can help clinicians tailor treatment strategies to address specific areas of concern for the patient, potentially improving adherence and outcomes.

Furthermore, in research, the CU-Q2oL serves as a valuable tool for:

Quantify the burden of chronic urticaria on patients’ lives.
Evaluate the effectiveness of new therapies and interventions in clinical trials.
Compare QoL across different patient populations or disease severities.
Conduct epidemiological studies on the impact of CU.

Quality of Recovery-15 (QoR-15): A Full Guide for Researchers and Clinicians.

Ali Hmidoush — Tue, 13 May 2025 18:14:54 +0000

Introduction

The Quality of Recovery-15 (QoR-15) is a significant and widely utilized patient-reported outcome measure (PROM) designed to assess the quality of recovery in patients following surgery and anesthesia. Developed by Paul S. Myles, Paul Stark, and Justin Burke in 2013, the QoR-15 provides a concise yet comprehensive evaluation of a patient’s postoperative state, moving beyond traditional morbidity and mortality metrics to capture aspects of recovery that matter most to patients. Moreover, This tool is invaluable for researchers and clinicians aiming to understand and improve the postoperative experience, focusing on physical comfort, emotional well-being, psychological support, physical independence, and pain levels. Furthermore, Its robust psychometric properties and ease of use have led to its widespread adoption in perioperative research and clinical settings globally.

Key Features of the Quality of Recovery-15

Purpose and Use

The QoR-15 stands out for its patient-centered approach to measuring postoperative recovery. It evaluates how surgical interventions and anesthetic procedures impact a patient’s daily functioning and overall well-being after discharge. Also, This questionnaire enables researchers and healthcare providers to gain a holistic understanding of the recovery trajectory by encompassing a range of important outcomes.

Target Population

The QoR-15 is designed for use in adult patients aged 18 years and older who have undergone surgery and anesthesia. This includes:

Young Adults (18–24 years)
Middle-Aged Adults (25–44 years)
Older Adults (45–64 years)
Seniors (65+ years)
College/University Students (if they fall within the adult age range and are postoperative patients)
Parents (if they are postoperative patients)

Essentially, any adult patient recovering from a surgical procedure can be assessed using the QoR-15, so this can make it a versatile tool for diverse research cohorts.

Structure

The QoR-15 questionnaire comprises 15 items that assess different aspects of a patient’s recovery. Each item evaluates symptoms, functional status, and emotional well-being. For instance, questions might inquire about the severity of pain, the ability to perform daily activities like eating or mobilizing, and feelings of anxiety or depression.

The 15 items are conceptually grouped into five domains:

Physical Comfort: Pertains to symptoms like nausea, vomiting, and general discomfort.
Emotional State: Assesses feelings such as anxiety, depression, or general well-being.
Physical Independence: Focuses on the patient’s ability to look after themselves, such as mobility and self-care.
Psychological Support: Relates to feelings of support and reassurance.
Pain: Specifically evaluates the level of pain experienced by the patient.

Scoring Method

Each of the 15 items in the QoR-15 is scored on an 11-point numerical rating scale, ranging from 0 (none of the time/worst outcome) to 10 (all of the time/best outcome). The total score is calculated by summing the scores for each of the 15 items, resulting in a possible range from 0 (very poor recovery) to 150 (excellent quality of recovery).

The interpretation of the total score is generally as follows:

Excellent Recovery: QoR-15 score > 135
Good Recovery: QoR-15 score between 122 and 135 (inclusive)
Moderate Recovery: QoR-15 score between 90 and 121 (inclusive)
Poor Recovery: QoR-15 score < 90
A score below 90 is a widely accepted cut-off indicating poor recovery and potentially signaling the need for further clinical attention.

Additionally, no special training is required to administer or interpret the questionnaire, as it is self-administered with basic instructions.

Administration Format

The QoR-15 index can be administered in the following formats:

Paper-based (clinician-administered)
Digital forms (online or electronic)
In-person interviews
Phone/Video Call

Due to its clinical nature, QoR-15 typically requires healthcare professionals for accurate administration.

Applications of the Quality of Recovery-15

The QoR-15 supports both clinical and research applications, actively enhancing postoperative care. In clinical practice, clinicians use it to screen patients for poor recovery, monitor progress, and drive quality improvement by identifying gaps in care. Meanwhile, in research, the tool plays multiple roles. It serves as an endpoint in clinical trials, supports comparative studies across populations and procedures, and strengthens predictive modeling by identifying at-risk patients for early intervention. Furthermore, researchers rely on it to assess the quality and effectiveness of health services. Thus, the QoR-15 consistently enables timely, data-driven decisions in healthcare.

Languages and Availability

The QoR-15 has been translated and validated in multiple languages to facilitate its use in diverse international research and clinical settings. Available languages include:

English
Arabic
Mandarin Chinese
Spanish
French
German
Portuguese
Japanese

The questionnaire is generally free for use, particularly for non-commercial research and clinical applications.

Reliability and Validity

The QoR-15 is recognized for its strong psychometric properties, making it a reliable and valid tool for assessing postoperative recovery.

Reliability: The questionnaire demonstrates good internal consistency, with a reported Cronbach’s alpha of 0.84. This indicates that the items within the scale are well-correlated and consistently measure the same underlying construct of recovery quality.
Validity: The QoR-15 has undergone extensive validation across various surgical populations and languages. Moreover, It has shown good construct validity, correlating well with other measures of recovery, pain, and overall health status.

Limitations and Considerations

Despite its many strengths, the QoR-15 has a few limitations that researchers and clinicians should consider:

Self-report Measure: As a patient-reported outcome measure, scores can be influenced by individual patient interpretation, mood, or recall bias.
Social Desirability Bias: Patients may sometimes respond in a way they perceive as more socially acceptable, potentially affecting the accuracy of their reported symptoms or functioning.
Ceiling/Floor Effects: In some specific patient populations or at certain time points, there might be ceiling effects (many patients scoring the maximum) or floor effects (many patients scoring the minimum), which could limit the ability to detect changes.
Focus on Early Recovery: While excellent for acute and subacute recovery, its utility for very long-term recovery monitoring might be less pronounced compared to more general quality of life instruments.

Scoring Atopic Dermatitis (SCORAD) Index: A Full Guide for Researchers and Clinicians.

Ali Hmidoush — Tue, 13 May 2025 13:08:32 +0000

Introduction

Atopic Dermatitis (AD), commonly known as eczema, is a chronic inflammatory skin disorder affecting both children and adults. Reliable assessment tools are critical to monitor disease severity, plan treatment, and evaluate outcomes in clinical practice and research. The Severity Scoring of Atopic Dermatitis (SCORAD) index, developed by the European Task Force on Atopic Dermatitis (ETFAD) in 1993, is one of the most widely used clinician-administered tools for assessing AD.

This article offers a comprehensive overview of the SCORAD index, its purpose, scoring method, validation, and practical applications. Whether you’re a researcher or clinician, understanding SCORAD can help ensure accurate, evidence-based evaluation of eczema severity.

Key Features of the Scoring Atopic Dermatitis Index

Purpose and Use

The SCORAD index is designed to assess the severity of atopic dermatitis through three components:

Extent of skin involvement (body surface area).
Intensity of six clinical signs (e.g., erythema, edema).
Subjective symptoms such as itch and sleep disturbance.

This multifaceted approach allows clinicians to evaluate both objective and patient-reported symptoms, making SCORAD essential for diagnosis, monitoring, and research.

Target Population

The Scoring Atopic Dermatitis is validated for use across all age groups, including:

Children (under 13 years)
Adolescents
Young and middle-aged adults
Older adults and seniors

Its broad applicability enhances its usefulness in pediatric and adult dermatology.

Domains and Sub-domains

Main Domain:

Dermatology / Skin Health

Sub-domains:

Extent – Body surface area affected
Intensity – Clinical signs (e.g., oozing, lichenification)
Subjective Symptoms – Itch and sleep disturbance

Structure

SCORAD consists of:

1 item for extent
6 items for intensity (scored 0–3 each)
2 items for subjective symptoms (scored 0–10 each)

Scoring Method

The SCORAD score is calculated using the following formula:

A/5 + 7B/2 + C

Where:

A = Extent (% of body surface area, calculated via the “rule of 9s”)
B = Intensity score (0–18)
C = Subjective symptoms (0–20)

Score Interpretation:

Mild AD: <25
Moderate AD: 25–50
Severe AD: >50

This formula provides a maximum score of 103, reflecting overall disease severity.

Administration Format

The SCORAD index can be administered in the following formats:

Paper-based (clinician-administered)
Digital forms (online or electronic)
In-person interviews

Due to its clinical nature, SCORAD typically requires healthcare professionals for accurate administration.

Applications of the Scoring Atopic Dermatitis Index

SCORAD is used for:

Screening: Identifying AD severity

Domains and Sub-domains

The FACT-P consists of two main sections:

FACT-G: A general section that covers four domains:
- Physical Well-Being (PWB)
- Social/Family Well-Being (SWB)
- Emotional Well-Being (EWB)
- Functional Well-Being (FWB)
Prostate Cancer Specific Section: Focuses on issues unique to prostate cancer patients, such as urinary symptoms, sexual health, and the side effects of treatment.

Scoring Method

The scoring system for the FACT-P uses a 5-point Likert scale (from 0 to 4). Scores are calculated across different domains and subscales:

Physical Well-Being: 7 items, total score range 0-28
Social/Family Well-Being: 7 items, total score range 0-28
Emotional Well-Being: 6 items, total score range 0-24
Functional Well-Being: 7 items, total score range 0-28
Prostate Cancer Specific Scale: 12 items, total score range 0-48

The total score is calculated by summing the scores across all domains, providing a range of 0 to 156.
