Summary
Intervention fidelity in Qigong studies is often poorly reported, impacting research reliability. A proposed plan aims to improve Qigong intervention fidelity for more valid health outcome studies.
Area of Science:
- Integrative and Complementary Medicine
- Clinical Trial Methodology
- Health Services Research
Background:
- Intervention fidelity is crucial for ensuring the reliability and validity of research findings.
- Qigong exercise interventions are widely recognized for their health benefits, but their implementation quality requires scrutiny.
- Assessing intervention fidelity in Qigong studies is essential for understanding the consistency and accuracy of program delivery.
Purpose of the Study:
- To evaluate the quality of intervention fidelity in published Qigong randomized controlled studies.
- To assess adherence to intervention fidelity across five key domains: design, training, delivery, receipt, and enactment.
- To propose a standardized intervention fidelity plan tailored for Qigong research.
Main Methods:
- A systematic review of 32 Qigong randomized controlled studies selected from a pool of 86 articles across CINAHL, PubMed, AMED, and Scopus databases.
- Utilized a valid intervention fidelity assessment tool to analyze the five domains: design, training, delivery, receipt, and enactment.
- Quantified adherence rates for intervention fidelity strategies within each domain.
Main Results:
- Adherence rates for intervention fidelity strategies were highest in intervention design (0.66) and lowest in receipt (0.12) and enactment (0.21).
- Training (0.32) and delivery (0.22) also showed suboptimal adherence.
- Findings indicate inadequate implementation and/or reporting of intervention fidelity in published Qigong studies.
Conclusions:
- Published Qigong research demonstrates significant deficiencies in intervention fidelity, potentially compromising study validity and replicability.
- There is a critical need for developing and implementing consistent intervention fidelity plans in Qigong research.
- A specific treatment fidelity plan for Qigong interventions is proposed to enhance research quality and consistency.

Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest. Among the various sampling methods used by...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.

Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:
