摘要

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.
