There has been a growing demand for evidence-based interventions to help students prepare for the transition between university and the world of work. The aim of this study was to investigate the effects of a career counseling intervention, in groups and online, on the career adaptability resources and perceptions of professional development and employability of college students in the final stage of their undergraduate courses. The study was based on career construction theory and the theoretical model for professional development of college students. As a preliminary activity, the intervention was performed with a pilot group (n = 20), followed by the actual experiment with an IG (n = 14) and an N-TG (n = 14). Based on a detailed protocol, the intervention was applied for three months, with six weekly sessions and a follow-up session one month after the end of the intervention. Between the sessions, the participants were expected to accomplish directed tasks. Two observers were part of the experiment and elaborated reports of each session. The Linear Mixed Regression Model (LMM) and the Jacobson and Truax (JT) Method were used to evaluate the effectiveness of the intervention, comparing each participant with themself before and after the intervention. The results show that career counseling with graduating college students expands their career adaptability resources, and their perceptions of professional development and employability. The no-treatment group did not present an increase in the score's dimensions over time. Therefore, based on the study, career counseling interventions can be recommended for college students to promote proactive action to anticipate barriers and increase awareness of possibilities and work interests among participants.

对基于证据的干预措施的需求不断增长，以帮助学生为大学和工作世界之间的过渡做好准备。本研究的目的是调查职业咨询干预，以团体和在线的方式，对大学生在本科最后阶段的职业适应性资源和职业发展和就业能力的看法的影响。本研究基于职业生涯建构理论和大学生职业发展理论模型。作为初步活动，干预是在试验组 ( n  = 20) 中进行的，然后是使用 IG ( n  = 14) 和 N-TG ( n = 14). 根据详细的协议，干预实施了三个月，每周进行六次治疗，干预结束后一个月进行一次随访。在会议之间，参与者被期望完成定向任务。两名观察员参与了实验，并详细阐述了每次会议的报告。线性混合回归模型 (LMM) 和 Jacobson 和 Truax (JT) 方法用于评估干预的有效性，将每个参与者在干预前后与自己进行比较。结果表明，对即将毕业的大学生进行职业咨询扩展了他们的职业适应性资源，以及他们对职业发展和就业能力的看法。随着时间的推移，未治疗组的评分维度没有增加。所以，
