Randomized Trial Investigating of a Single

To investigate the efficiency of a single-session character-strength-based cognitive intervention on enhancing freshmen’s adaptability. A randomized trial, pretest, posttest, follow-up intervention was employed using repeated-measures analyses to evaluate the effect. This 90-min intervention contained four activities with 52 undergraduate freshmen (age 17–20) randomly assigned to the intervention and control group, 38 of whom completed all the programs (19 of each group). Compared with the control group, the intervention group showed a remarkable increase in well-being and a significant reduction in depression and anxiety at post and follow-up assessment. The stress level of the intervention group significantly decreased only at the follow-up test. Time effect and the interaction between time and group were significant in anxiety and stress. This intervention can quickly reduce negative affect and elevate well-being for freshmen. It expands the role of social worker in the prevention of mental illness among college population
