Summary
The Suboptimal Health Status Questionnaire-25 (SHSQ-25) was adapted for Turkish nurses, demonstrating high reliability and validity. This validated tool aids in identifying and managing suboptimal health status in this population.
Area of Science:
- Public Health
- Health Psychology
- Nursing Research
Background:
- Suboptimal health status (SHS) is a reversible pre-disease condition requiring effective measurement tools.
- Existing questionnaires need cultural adaptation for diverse populations to inform personalized medical practices.
- Nurses are a critical population for monitoring and managing SHS.
Purpose of the Study:
- To translate and culturally adapt the Suboptimal Health Status Questionnaire-25 (SHSQ-25) into Turkish.
- To evaluate the psychometric properties, including validity and reliability, of the Turkish version of the SHSQ-25 among Turkish nurses.
Main Methods:
- The SHSQ-25 was administered to 247 nurses at Muğla Training and Research Hospital.
- Confirmatory Factor Analysis (CFA) was used to assess construct validity.
- Reliability was evaluated using Cronbach's alpha, content validity index, and intraclass correlation coefficients (ICC) for test-retest reliability.
Main Results:
- The Turkish SHSQ-25 demonstrated excellent reliability (Cronbach's α = 0.95, CVI = 0.78).
- Goodness-of-fit indices from CFA indicated a perfect fit for the scale's structure.
- High test-retest reliability was confirmed with ICC values ranging from 0.64 to 0.89 and Spearman's rho of 0.76.
Conclusions:
- The Turkish version of the SHSQ-25 is a valid and reliable instrument for measuring suboptimal health status in Turkish nurses.
- This validated scale can be utilized in clinical practice and research to identify and address SHS within this demographic.

01:29Assessment of the Gastrointestinal System II: Health Perception Pattern
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:

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
