| Summary: | Abstract Background Home-visiting nurses are required to recognize risks in their work, ensure patient safety according to the characteristics of home-visiting nursing, and therefore, effectively support stability in patients’ lives. In this study, we created a scale measuring home-visiting nurses’ attitudes toward patient safety and examined its reliability and validity. Methods A total of 2,208 home-visiting nurses from Japan were randomly selected as participants. From the 490 responses collected (response rate: 22.2%), 421 responses with no missing values, other than those related to participants’ basic information (valid response rate: 19.0%), were analyzed. Participants were randomly divided into two groups: 210 for exploratory factor analysis (EFA) and 211 for confirmatory factor analysis (CFA). To examine the reliability of the home-visiting nurses attitude scale developed in this study, ceiling and floor effects, inter-item correlations, and item-total correlations were checked. Subsequently, EFA was performed to confirm the factor structure. CFA, composite reliability, average variance extracted, and Cronbach’s alpha for each factor were extracted to confirm the factor structure of the scale and the validity of the model. Results The home-visiting nurses’ attitudes toward patient safety were measured using 19 questionnaire items related to four factors: “Self-improvement for patient safety,” “Incident awareness,” “Counter measures based on incident experience,” and “Nursing care to protect the lives of patients.” Cronbach’s α coefficients were 0.867, 0.836, 0.773, and 0.792 for Factors 1–4, respectively. Model indicators were χ2 = 305.155, df = 146, p < 0.001, TLI = 0.886, CFI = 0.902, RMSEA = 0.072 (90% confidence interval 0.061–0.083). Conclusions From the results of the CFA, criterion-related validity, and Cronbach’s α coefficient, this scale is considered reliable and valid and thus, highly appropriate. Therefore, it may be effective at measuring home-visiting nurses’ attitudes toward patients’ medical safety from both behavioral and awareness aspects.
