本研究旨在探討職業安全衛生教育訓練頻率與職業災害發生率之關聯性，以北部某電子製造廠員工為研究對象進行實證分析。現行台灣《職業安全衛生教育訓練規則》多以「三年三小時」作為一般勞工之最低訓練門檻，然該訓練模式多採集中式辦理，其是否足以維持勞工長期之安全認知與安全行為，仍缺乏具體且長期的實證支持。相較之下，國際間多數先進國家已逐步導入年度再訓或高頻次教育訓練制度，顯示訓練頻率可能為影響職災防制成效之關鍵因素之一。 本研究在總訓練時數相同之前提下，比較兩種不同教育訓練週期制度對安全績效之影響，分別為 2020 至 2022 年實施之「三年一次集中式訓練模式」，以及 2023 至 2025 年實施之「每年一次分次訓練模式」。研究結合量化問卷調查與企業實際職業災害紀錄資料，蒐集 106 份有效問卷，並以失能傷害頻率（Disabling Injury Frequency Rate， DIFR）作為客觀事故指標，以全面評估教育訓練頻率對勞工安全認知、安全行為及職業災害發生率之影響。 研究方法採用信度分析、描述性統計及獨立樣本 t 檢定進行資料分析，並依據 Neal 與 Griffin（2006）之安全績效理論模型，建構「教育訓練頻率 →安全認知→安全行為→職災發生率」之因果關係架構。 研究結果顯示，在訓練頻率提升後，企業整體失能傷害頻率由 3.18 明顯下降至 1.44，顯示高頻次教育訓練對降低職業災害具有顯著效果。此外，不論高風險或低風險作業員工，其安全認知與安全行為表現皆未呈現顯著差異，顯示在標準化課程設計下，不同風險暴露群體皆能獲得相近且穩定的學習成效。 綜合研究結果可知，相較於單純累積訓練時數，教育訓練頻率對於維持勞工安全認知、促進安全行為內化及降低職業災害發生率，具有更為關鍵之影響。本研究之發現不僅補足國內針對教育訓練頻率與職災關聯性之實證研究缺口，亦可作為企業規劃安全衛生教育訓練制度之參考依據。研究結果同時建議，政府相關單位於未來修訂教育訓練制度時，除考量訓練時數外，亦應將訓練頻率與持續性納入制度設計，以提升整體職業安全衛生管理成效。;This study investigates the relationship between the frequency of occupational safety and health (OSH) training and workplace injury occurrence， using employees from an electronics manufacturing plant in northern Taiwan as the research sample. Under Taiwan’s current Regulations for Occupational Safety and Health Education and Training， general employees are required to complete only three hours of safety training within a three-year period. In practice， this requirement is often fulfilled through a one-time， concentrated training session. However， whether such a low-frequency training model is sufficient to sustain workers’ safety awareness and safe behaviors over time remains insufficiently supported by empirical evidence. In contrast， many industrialized countries have adopted annual or high-frequency refresher training systems， suggesting that training frequency may play a critical role in injury prevention effectiveness. To address this issue， this study compares two OSH training systems with identical total training hours but different training cycles: a triennial， concentrated training model implemented between 2020 and 2022， and an annual， distributed training model implemented between 2023 and 2025. The research integrates quantitative questionnaire data and objective workplace injury records， including 106 valid employee questionnaires and three years of occupational injury data. The Disabling Injury Frequency Rate (DIFR) is adopted as the primary objective indicator to evaluate the impact of training frequency on safety cognition， safety behavior， and occupational injury outcomes. Data analysis was conducted using reliability analysis， descriptive statistics， and independent-samples t-tests. Based on the safety performance model proposed by Neal and Griffin (2006)， this study establishes a causal framework linking training frequency， safety cognition， safety behavior， and occupational injury rates. The results indicate that after increasing training frequency， the DIFR decreased significantly from 3.18 to 1.44， demonstrating a substantial improvement in workplace safety performance. Furthermore， no statistically significant differences were found between high-risk and low-risk workers in terms of safety cognition and safety behavior， suggesting that standardized training programs can produce consistent learning outcomes across different levels of risk exposure. Overall， the findings confirm that training frequency plays a more critical role than total training hours alone in sustaining safety cognition， reinforcing safe behaviors， and reducing occupational injury rates. This study fills an important empirical gap in domestic research on OSH training frequency and provides practical evidence for enterprises seeking to optimize their safety training systems. In addition， the results offer policy implications for regulatory authorities， suggesting that future revisions of OSH training regulations should emphasize not only minimum training hours but also training frequency and continuity to enhance long-term injury prevention effectiveness.
