Background:
Patient engagement in medication safety is a recognized public health priority that reduces preventable harm and improves clinical outcomes. Despite its importance, Malaysia lacks a validated Malay-language instrument to assess inpatient involvement in medication safety, limiting efforts to tailor interventions and monitor engagement.
Objective:
This study aimed to translate, culturally adapt, and psychometrically validate the Inpatient Medication Safety Involvement Scale (IMSIS) for use among Malay-speaking adult inpatients.
Methods:
A cross-sectional study was conducted among 100 adult inpatients across four wards of a tertiary hospital in Kelantan, Malaysia. The eight-item IMSIS was translated using ISPOR cross-cultural adaptation guidelines, including forward-back translation, expert review, and cognitive debriefing. Content and face validity indices were calculated. Confirmatory factor analysis (CFA) assessed construct validity, and internal consistency was evaluated using Raykov's rho.
Results:
The Malay IMSIS demonstrated excellent content (S-CVI = 0.94) and face (S-FVI = 0.87) validity. CFA supported a single-factor structure with acceptable fit after allowing a residual correlation between two self-administration items (χ2 (17) = 27.5, CFI = 0.98, RMSEA = 0.08, SRMR = 0.04). All standardized loadings were ≥0.60, and composite reliability was high (Raykov's ρ = 0.90). The instrument showed good interpretability, with higher scores reflecting greater medication-safety engagement.
Conclusion:
The Malay version of the IMSIS (M-IMSIS) is a brief, culturally appropriate, and psychometrically sound tool for assessing inpatient involvement in medication safety. It supports national and global efforts to enhance patient-centered care and can inform quality improvement initiatives in Malaysia and similar middle-income settings.
Insights
A new Malay-language tool, the Inpatient Medication Safety Involvement Scale (IMSIS), has been validated for use in Malaysia. This scale effectively measures patient engagement in medication safety among Malay-speaking inpatients.
Area of Science:
- Health Services Research
- Patient Safety
- Psychometrics
Background:
- Patient engagement is crucial for medication safety and improving health outcomes.
- Malaysia lacks a validated Malay-language tool to assess inpatient involvement in medication safety.
- This gap hinders tailored interventions and engagement monitoring.
Purpose of the Study:
- To translate and culturally adapt the Inpatient Medication Safety Involvement Scale (IMSIS).
- To psychometrically validate the adapted scale for Malay-speaking adult inpatients in Malaysia.
Main Methods:
- Cross-sectional study with 100 adult inpatients in Kelantan, Malaysia.
- Translation and cultural adaptation followed ISPOR guidelines.
- Content validity, face validity, construct validity (CFA), and internal consistency (Raykov's rho) were assessed.
Main Results:
- The Malay IMSIS (M-IMSIS) showed excellent content (S-CVI=0.94) and face (S-FVI=0.87) validity.
- Confirmatory factor analysis supported a single-factor structure with acceptable fit.
- High internal consistency (Raykov's ρ=0.90) and interpretability were demonstrated.
Conclusions:
- The M-IMSIS is a brief, culturally appropriate, and psychometrically sound tool.
- It can be used to assess inpatient involvement in medication safety in Malaysia.
- The tool supports patient-centered care initiatives in middle-income settings.
