Summary
This study introduces the Menstrual Health Literacy Scale (MHLS-22), a new tool to measure menstrual health literacy. The MHLS-22 is a validated and reliable scale for assessing understanding of menstruation and its health impacts.
Area of Science:
- Public Health
- Health Literacy
- Women's Health
Background:
- Menstrual health literacy (MHL) is crucial for effective menstrual health management.
- Understanding MHL's impact on overall health and well-being is essential.
- A validated scale to measure MHL was previously lacking.
Purpose of the Study:
- To develop and psychometrically validate the first scale measuring MHL.
- To propose a novel conceptual definition of MHL.
- To provide a reliable tool for MHL assessment and intervention evaluation.
Main Methods:
- Scale development involved item generation and content validity analysis.
- Psychometric validation included exploratory and confirmatory factor analysis.
- Convergent and discriminant validity testing were performed to ensure accuracy.
Main Results:
- The 22-item Menstrual Health Literacy Scale (MHLS-22) was developed.
- Psychometric analyses confirmed the validity and reliability of the MHLS-22.
- The scale is suitable for evaluating MHL and intervention effectiveness.
Conclusions:
- The MHLS-22 is the first psychometric scale to measure MHL.
- The scale demonstrates strong validity and reliability.
- MHLS-22 can be used to assess MHL and guide interventions for improved menstrual health.

01:21Health Literacy
5.8K
Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

01:19The Menstrual Cycle
5.8K
The menstrual cycle is a recurrent sequence of changes in the uterine endometrium, specifically its functional layer, the stratum functionalis. This cycle prepares the uterus for potential pregnancy. This cycle typically spans 21–35 days, averaging 28 days, and aligns with the ovarian cycle, regulated by fluctuating levels of ovarian hormones, primarily estrogen and progesterone.
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a...

01:18Menses Phase
1.4K
The uterine cycle begins with the menstrual phase, which is considered day one of the cycle and typically lasts about five days. This phase is characterized by the degeneration and shedding of the stratum functionalis, the functional layer of the endometrium.
When fertilization does not occur, the corpus luteum deteriorates, causing a significant drop in the levels of estrogen and progesterone in the body. This hormonal decrease triggers the release of prostaglandins, which cause the uterine...

01:29Assessment of the Gastrointestinal System II: Health Perception Pattern
582
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

01:22Hormonal Regulation of the Menstrual Cycle
2.2K
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

7.2K
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
