本文主要探討我國警察工作上使用通訊軟體對工作績效的影響，以及使用通訊軟體所造成的工作干擾與工作負荷，是否具有中介效果，對警察個人的工作績效產生影響。本研究採用多元線性迴歸分析，經實證結果發現：（1）警察工作上使用通訊軟體，可以提升個人工作績效。（2）通訊軟體之公務使用不會對警察造成工作干擾（3）通訊軟體之公務使用會對警察造成工作負荷。（4）工作干擾與工作負荷可以增加警察的任務績效。（5）工作干擾與工作負荷不會對警察的脈絡績效產生影響。（6）警察使用通訊軟體所造成的工作干擾與工作負荷，都不具有中介效果，對個人的工作績效產生影響。

The purpose of this study is to examine the influences of using instant messaging at work on policemen in Taiwan, and whether the work interruption and workload that using instant messaging made have meditation effect to policemen personal job performance. For this paper, multiple Linear regression analysis was conducted in an empirical study with following findings：（1）policemen using instant messaging at work can enhanced personal job performance;（2）policemen using instant messaging at work couldn’t make work interruption;（3）policemen using instant messaging at work could make workload;（4）work interruption and workload can enhanced task performance of policeman;（5）work interruption and workload could not affect contextual performance of policeman;（6）work interruption and workload that policemen using instant messaging made didn’t have meditation effect to affect personal job performance.
