Effectiveness of Finger Safety Intervention Module (FingSIM) in increasing finger safety knowledge among Small and Medium Enterprise (SME) manufacturing industries in Selangor

Introduction: Occupational finger accidents and injuries (OFAI) are prevalent among Malaysian employees. An analysis of accident statistics from the Department of Occupational Safety and Health (DOSH) Malaysia revealed that 26.25% of accidents between 2017 and 2019 involved finger injuries. This study aims to evaluate the effectiveness of the self-developed Finger Safety Intervention Module (FingSIM) in enhancing finger safety knowledge among manufacturing workers in small and medium enterprises (SMEs). Materials and methods: This quasi-experimental study, involving control and intervention groups from 14 manufacturing companies in Selangor, used G*Power v3.1 to determine sample sizes. Employing a pre-test, post-test, and second-post-test, data on finger safety knowledge were collected via the validated FingSTEv questionnaire. Mixed ANOVA compared mean differences within-subject (time and group) and between-subject (group) across three time intervals. Results: The results showed a significant increase in mean knowledge scores across all three time intervals (p<.05), with a very large effect size (partial eta squared = .549). The interaction between time and group on knowledge scores within subjects also demonstrated a very large effect (partial eta squared = .553, p<.05). Similarly, the interaction effect between time and group on knowledge scores between subjects was substantial (partial eta squared = .510, p<.05). Conclusion: The study found that implementing FingSIM significantly improved manufacturing workers' finger safety knowledge in SMEs, demonstrating its effectiveness and meeting the research objectives.
