The traditional prevailing perspectives on attitudes assume that attitudes, once formed, are relatively stable over time. However, research has revealed that attitudes may be influenced by different factors that may change them. The present pre-post-test study aims to understand if the police recruits’ attitudes towards offenders change after police training and analyse the impact of sociodemographic and personality variables on recruits’ attitudes towards offenders. The Attitude Scale towards Offenders (ATO) and the NEO-FFI Personality Inventory were used in a sample of 74 recruits of a Portuguese Police Force at the beginning and the end of the police training program. Results revealed that, at the end of the training, recruits hold more negative attitudes towards offenders. Those who had previous professional experience in the army hold more positive attitudes, but only at the beginning of the training. Only attitudes towards offenders at the beginning of the police training program predict recruits’ attitudes towards offenders at the end of the training. These results emphasize the importance of initial and continuous training of recruits and police officers.

关于态度的传统流行观点假设态度一旦形成，就会随着时间的推移相对稳定。然而，研究表明，态度可能会受到可能改变态度的不同因素的影响。目前的前后测研究旨在了解警察新兵在警察培训后对罪犯的态度是否发生变化，并分析社会人口统计学和人格变量对新兵对罪犯态度的影响。在警察培训计划的开始和结束时，对犯罪者的态度量表 (ATO) 和 NEO-FFI 人格量表被用于葡萄牙警察部队的 74 名新兵样本。结果显示，在培训结束时，新兵对违法者的态度更为消极。那些以前在军队中有过专业经验的人持有更积极的态度，但只是在训练开始时。只有在警察培训计划开始时对罪犯的态度才能预测新兵在培训结束时对罪犯的态度。这些结果强调了对新兵和警察进行初始和持续培训的重要性。
