Depression is common among university students, and campus clinics often have more demand than they can meet. A randomised controlled trial tested whether short versions of two psychological treatments could help. Fifty students with major depression were assigned either to four sessions of mindfulness-based therapy, four sessions of behavioural activation, or a waiting list.
Mindfulness-based therapy teaches people to notice thoughts and feelings without being swept along by them. Behavioural activation helps people re-engage with rewarding and meaningful activities that depression has crowded out. Both treatments did better than the waiting list. Students improved on measures of depression, rumination (repetitive negative thinking) and stress, and most of those gains held at a one-month follow-up. Neither therapy reduced physical symptoms of anxiety. Depending on the measure used, between 56 and 79 per cent of treated students showed clinically meaningful improvement, and between 75 and 85 per cent had reliable reductions in depression. Satisfaction with both treatments was high.
Brief, structured therapy will not suit everyone, and this was a small study. Even so, it suggests that a few well-delivered sessions can shift depression for some people. If low mood is affecting your study, work or relationships, a GP or psychologist is a good place to start.
What the researchers did
This was a randomised controlled trial with 50 university students who met criteria for major depressive disorder. Each was randomly assigned to one of three groups: four sessions of abbreviated mindfulness-based therapy, four sessions of behavioural activation, or a waiting-list control. Randomisation matters. It spreads out the differences between people, so that any change afterwards is more likely to reflect the treatment than the mix of who ended up in which group.
Mindfulness-based therapy trains attention to present-moment experience and a non-judgemental stance towards thoughts and feelings. Behavioural activation works differently. It focuses on planning and re-engaging with activities that bring a sense of reward or meaning, on the basis that withdrawal and inactivity keep depression going. Both were delivered in a shortened four-session form to fit the demands of a college counselling service. Outcomes were analysed on an intention-to-treat basis, which means every participant was counted in the group they were assigned to, whether or not they finished treatment. That approach gives a more conservative and realistic estimate of how a treatment performs.
What they found
Both active treatments outperformed the waiting list. Students in either therapy improved significantly from before to after treatment on depression, rumination, stress and mindfulness. Rumination here means the habit of turning the same distressing thoughts over and over without reaching a resolution, a pattern closely tied to low mood. Most of those gains were still present one month later. Neither treatment produced a meaningful reduction in the bodily symptoms of anxiety.
The effect sizes for both therapies against the control group were generally moderate to strong. Using standard thresholds for treatment response and remission, 56 to 79 per cent of treated students showed clinically significant improvement. Using reliable change indices, which ask whether a person's change is larger than measurement error alone, 75 to 85 per cent showed clinically significant reductions in depression. Therapists kept closely to the treatment protocols, and satisfaction with both interventions was high.
Why it matters in practice
Waiting lists at student services are a real barrier to care. Long courses of therapy are not always feasible within a single semester. Evidence that four focused sessions of a well-defined approach can produce measurable improvement gives clinicians and services a practical option, whether as a first step or as support while someone waits for longer-term treatment. Both approaches used here teach skills that people can keep applying after therapy ends. They are also structured approaches with clear protocols, and the study reported that therapists delivered them with high adherence and that students were satisfied with both.
The limits
This was a single small trial in one specific group: university students at a campus clinic. The results may not carry over to older adults, to people with more severe or long-standing depression, or to those with significant co-occurring conditions. Follow-up ran to only one month. Nothing here speaks to whether the improvements lasted a semester or a year. The study found no benefit for physical anxiety symptoms, and for some people a brief course will simply be too short. These findings are a reason to consider short, focused therapy as one option among several. A psychologist or GP can help judge whether it fits your situation, or whether something more intensive is needed.
