As adult students constitute nearly half of all undergraduates in the United States, college practitioners need to identify effective disciplinary strategies for this population when violations of institutional rules and regulations occur. The purpose of this quasi-experimental, action research study was to modify the student conduct process for adult students referred to State University's Student Conduct & Community Standards in order to improve the desired learning outcomes: increased awareness of institutional policies, improved ability to understand the impact misconduct has on the campus community, enhanced ability to empathize with the other party involved in the incident, better understanding of the short-term and long-term consequences associated with student misconduct, and reduced likelihood of future recidivism. Multi-dimensional behavioral interventions (i.e., active and passive sanctions) were identified as a potential disciplinary strategy for adult students. To determine how adult students responded to multidimensional behavioral interventions and how effective this sanctioning approach was in increasing learning outcomes within this population, student questionnaires and seven-month recidivism data were utilized. Results, derived from a one-way ANOVA with a 0.05 significance level, confirmed that adult students who received multi-dimensional behavioral interventions exhibited significantly more observable intrinsic gains than students who received only active or passive sanctions: they viewed the conduct process more positively, better understood the views of others, better understood their responsibilities as members of the campus community, expressed more willingness to take responsibility for their actions, and were less likely to exhibit recidivistic behavior.
