This examine started designing and compiling a questionnaire in October 2022. After professional session and reliability and validity testing, the ultimate model of the questionnaire was accomplished in February 2023.
Venture evaluation
Excessive worth methodology
The overall scores of the 300 questionnaires have been sorted from highest to lowest. A complete of 84 topics with a complete rating of > 32 factors have been within the high-score group, and 81 topics with a complete rating of < 15 factors have been within the low-score group. The unbiased pattern t-test was used to check the distinction in every merchandise between the high-score and low-score teams. Apart from merchandise 6, “I’m afraid of being injured throughout train, so I dare not train,” all gadgets had t-values of > 3; the variations have been statistically important.
Merchandise-to-total correlation methodology
The Pearson correlation was used to check the correlation between every merchandise and the whole rating on the dimensions. Apart from gadgets 2 and 6, the correlation between every merchandise of the dimensions and the whole rating was > 0.3 (Desk 2).
Based mostly on the above statistical outcomes of the merchandise evaluation, the whole correlation coefficient of merchandise 2, “I imagine that train can forestall the incidence of ailments,” was < 3, and in merchandise 6, “I’m afraid of damage throughout train, so I dare not train,” the merchandise evaluation failed to fulfill the acute worth check and in addition failed to fulfill the statistical normal of the item-total rating correlation coefficient check. Subsequently, these two gadgets have been deleted.
Validity check
Content material validity
Within the current examine, the professional content material validity evaluation was adopted to check whether or not the content material or gadgets of the questionnaire may replicate the aim or diploma of the conduct to be measured. The outcomes confirmed that the I-CVI on the complete merchandise degree of the questionnaire on the influencing components was 0.833–1.000, and the I-CVI on the scale degree was 0.974, indicating good representativeness of the questionnaire.
Assemble validity
Within the current examine, issue evaluation was used to (1) analyze the assemble validity of the influencing components questionnaire, (2) discover the issue loadings and cumulative variance explanations of every dimension issue underneath completely different variables, and (3) additional discover whether or not the assemble validity of the questionnaire was applicable. The outcomes confirmed that the Kaiser–Meyer–Olkin worth was 0.927, and Bartlett’s sphericity check had a P worth of < 0.001; this indicated that the information have been appropriate for issue evaluation. Based mostly on the preconceived dimensions, the variety of components within the general assemble was set at 5, and the principal part evaluation methodology, along with the utmost variance methodology, was adopted to research every merchandise of the influencing issue questionnaire. The cumulative variance contribution charge was 65.84%, and the widespread diploma of every merchandise was > 0.3. The issue loading was > 0.4 (if the issue loading was < 4, it could not be displayed) (Desk 3, Fig. 2). By way of dimension division, the statistical outcomes confirmed that the organizational dimension, coverage dimension, and group surroundings dimension absolutely conformed to the preconceived dimension division; nevertheless, the statistical evaluation outcomes of the person dimension and interpersonal dimension have been completely different from the preconceived dimension.
Scree plot of exploratory components
Reliability check
A reliability check, also referred to as reliability evaluation, can replicate the reliability and stability of the evaluation instruments. Probably the most generally used reliability coefficient, Cronbach’s α coefficient, was adopted on this examine to measure the interior consistency of the questionnaire. The overall Cronbach’s α coefficient of the influencing components questionnaire was 0.955; Cronbach’s α coefficient of the person, interpersonal, organizational, group surroundings, and coverage dimensions have been 0.782, 0.814, 0.928, 0.912, and 0.971, respectively (Desk 4).
Subsequently, the official draft of the questionnaire on the influencing components of the scientific health literacy of nurses with 36 gadgets and 5 dimensions (particular person, interpersonal, organizational, group surroundings, and coverage dimensions) was decided. The query choices have been set into two classes: “sure” and “no”. Within the case of choosing “no,” the topic was given 0 factors. Within the case of choosing “sure,” the topic was given 1 level.
Investigation on the influencing components of the scientific health literacy of nurses
Sampling methodology and pattern dimension estimation
It was recommended within the related literature that the common pattern dimension of a regional investigation required not less than 500 topics [14]. Additionally, within the investigation exploring the influencing components of variables, the minimal pattern dimension ought to be 5–10 instances of the variety of variables [14].
$$mathrm{N }= [mathrm{the number of the variable }times (5-10)] instances [1+10mathrm{%}]$$
The current examine aimed to (1) examine the present standing of the scientific health literacy of nurses in tertiary hospitals in Baoding and (2) discover the influencing components. With consideration of 20% of the questionnaires being invalid, the pattern dimension ought to be not less than 600.
Questionnaire on the influencing components of the scientific health literacy of nurses
By means of literature evaluate and professional session and primarily based on the theoretical mannequin of socioecology, a questionnaire on the influencing components of the scientific health literacy of nurses with 36 gadgets in 5 dimensions (particular person, interpersonal, organizational, group surroundings, and coverage dimensions) was designed. The query possibility was set into two classes: “sure” and “no”. Within the case of “no,” the topic was given 0 factors. Within the case of “sure,” the topic was given 1 level.
Knowledge assortment
The comfort sampling methodology was adopted to pick out analysis objects. The precise sampling course of was as follows: the related individuals answerable for the municipal tertiary hospitals within the city space have been contacted, and with the consent of the individuals in cost, the hyperlink to the digital questionnaire was forwarded to the nurses within the municipal tertiary hospitals within the city space by way of WeChat for the issuing and assortment of the digital questionnaire. In February 2023, a survey was performed on the influencing components of 2566 nurses in tertiary hospitals, and 2400 legitimate questionnaires have been in the end collected.
Correlation evaluation of the connection between the person, interpersonal, organizational, group surroundings, and coverage dimensions and the scientific health literacy of nurses
The outcomes of the pairwise Pearson correlation evaluation revealed that the person, interpersonal, organizational, group surroundings, and coverage dimensions have been all positively correlated with the scientific health literacy of nurses; the correlation coefficients have been all > 0.3 (Desk 5).
Multivariate evaluation of the scientific health literacy of nurses
To additional analyze the influencing components of the scientific health literacy of nurses, literacy was taken because the dependent variable; moreover, the information with basic data that had statistical variations within the univariate evaluation along with the 5 dimensions that have been considerably correlated with scientific health literacy have been taken because the unbiased variables. A multiple-stepwise regression equation was constructed. The outcomes of the a number of stepwise regression equation confirmed that components reminiscent of interpersonal dimension, coverage dimension, balanced each day food plan, particular person dimension, group surroundings dimension, the persistence of train in each day life, academic background, job title, and organizational dimension, have been included within the equation; the above influencing components may clarify 28.9% of the whole variation of the scientific health literacy of nurses (the adjusted R2 = 0.289) (Desk 6).
Evaluation of every merchandise within the questionnaire on the influencing components of the scientific health literacy of nurses
The proportion of nurses who answered “no” within the questionnaire on the influencing components of the scientific health literacy of nurses was ranked from highest to lowest to show the established order of the existence of varied influencing components within the surveyed inhabitants (Desk 7).
