Summary
The Vietnamese Stroke Self-Efficacy Questionnaire (SSEQ-V) is a reliable and valid tool for assessing self-efficacy in stroke survivors. This culturally adapted questionnaire supports improved recovery and self-management interventions in Vietnam.
Area of Science:
- Neuroscience
- Rehabilitation Medicine
- Psychometrics
Background:
- Self-efficacy is crucial for stroke recovery.
- Accurate measurement of self-efficacy is essential for effective interventions.
- The Stroke Self-Efficacy Questionnaire (SSEQ) is a validated tool for English-speaking populations.
Purpose of the Study:
- To translate and culturally adapt the SSEQ into Vietnamese (SSEQ-V).
- To evaluate the reliability and validity of the Vietnamese version (SSEQ-V) for post-stroke patients.
Main Methods:
- Translation and cultural adaptation using Beaton's guidelines.
- Content validity index (CVI) assessed by 10 experts.
- Face validity tested on 10 patients.
- Factor analysis on 305 patients and reliability assessment on 80 replications.
Main Results:
- SSEQ-V achieved 100% CVI with excellent content and form suitability.
- High internal reliability (Cronbach's alpha > 0.95) and test-retest reliability (ICC = 0.979).
- Factor analysis confirmed a two-factor structure (daily activities, self-management) with high fit indices.
Conclusions:
- The SSEQ-V is a reliable and valid instrument for assessing self-efficacy in Vietnamese stroke patients.
- SSEQ-V can be utilized to develop targeted self-management intervention programs.
- Implementation of SSEQ-V can enhance stroke recovery in Vietnam.

01:29Reliability and Validity
13.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Self-efficacy is the belief in one's capacity to organize and execute actions necessary to manage prospective situations. This belief significantly influences how individuals approach goals, tasks, and challenges across different domains of life.Psychological and Educational ImpactsIndividuals with strong self-efficacy are more resilient in the face of difficulties. They are more likely to adopt effective problem-solving strategies, persist through obstacles, and regulate emotions such as...

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.

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.

The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
