影响被告人供述的因素及其对策的研究

以１９５名执法人员和１８５名服刑犯人为被试，采用问卷法研究了影响被告人供述的因素以及相应的对策建议。结果表明：（１）有１０种因素被认为对被告人未能形成供述动机有影响作用，有９种因素被认为对被告人形成如实供述动机有影响作用，其中，执法人员所认为的影响作用基本上都比服刑犯人所认为的要大，同时，双方具有各自的倾向性；（２）有１５种因素被认为对愿意供述的被告人未能如实供述可能存在影响作用，其中６种因素确实有一定的影响；（３）有９种对策被普遍认为对解决被告人不愿供述问题有效，有１０种对策被认为对解决愿意供述的被告人未能如实供述的问题有效，同时，执法人员和服刑犯人在关于对策有效性的评价上具有互补性。
