Background:
Reliable and valid assessment tools are critical for evaluating and improving primary school students' hand hygiene behaviors, yet corresponding adaptable assessment methods are currently limited. We aimed to develop and validate a Hand Hygiene Behavior Questionnaire for Primary School Students (HHBQ-PSS).
Methods:
Cluster sampling recruited 376 Grade 4-5 students from two central primary schools. The 15-item HHBQ-PSS encompasses three dimensions (capability, opportunity, motivation) of hand hygiene, using a 5-point Likert scale. HHBQ-PSS was evaluated through internal consistency reliability, split-half reliability, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA).
Results:
The Cronbach's α coefficient of HHBQ-PSS was 0.844, and all Cronbach's α coefficients remained above 0.750 after corresponding dimensions were deleted. The Spearman-Brown coefficient was 0.784. EFA extracted four common factors (cumulative variance contribution rate = 58.67%). CFA confirmed adequate model fit (χ2/df = 2.832, CFI = 0.905, GFI = 0.927, AGFI = 0.893, and RMSEA = 0.070).
Implications For School Health Policy, Practice, And Equity:
The reliable and valid HHBQ-PSS may inform the implementation of targeted health interventions and the improvement of hand hygiene levels among primary school students.
Conclusion:
HHBQ-PSS demonstrates good reliability and validity to assess hand hygiene behaviors in Chinese primary school students.

The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail paint...

Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.

Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
