Single-Session Intervention for Mental Health Symptoms
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to help young adults better understand and improve their self-worth. It tests whether a single online session with a trained therapist, called the Single Session for Overevaluation, can positively impact participants' self-perception, particularly for those who overly focus on weight, shape, or muscular build. The trial seeks English-speaking young adults aged 18-25 who frequently overthink their appearance but have not experienced an eating disorder, either currently or in the past. Participants will complete questionnaires before and after the session to assess any changes. As an unphased trial, this study offers a unique opportunity to contribute to research that could help many young adults enhance their self-image.
Do I need to stop taking my current medications to join the trial?
The trial information does not specify whether you need to stop taking your current medications. It focuses on mental health and self-evaluation, so it's best to ask the trial organizers for more details.
What prior data suggests that this intervention is safe for young adults?
Research has shown that single-session interventions (SSIs) are generally safe for mental health treatment. One study found that participants experienced noticeable symptom improvements for up to six months after just one session. Another review of SSIs reported that 83% of the studies showed positive results, with no major safety concerns.
While these results are encouraging, the effectiveness and safety of SSIs can vary. Researchers continue to study this treatment, so individual experiences may differ. However, overall evidence suggests that single-session therapy is usually well-tolerated and lacks significant negative effects.12345Why are researchers excited about this trial?
Researchers are excited about the Single Session for Overevaluation intervention because it offers a quick, focused approach to addressing mental health symptoms in just one session. Unlike traditional therapies, which can involve multiple sessions over weeks or months, this method aims to provide immediate relief and insights. This approach is particularly appealing for individuals seeking rapid support without the long-term commitment typically required in therapy.
What evidence suggests that this single session intervention is effective for mental health symptoms?
Research has shown that single-session treatments can significantly reduce mental health issues in both young people and adults. Various studies indicate that about 83% of these treatments yield positive results. For instance, participants reported lasting decreases in depression symptoms even six months after just one session. Specifically, one study found that symptoms significantly reduced at follow-ups, even without additional support, with strong effects. Overall, single-session therapies, like the one tested in this trial, show promise for improving mental health by effectively addressing symptoms in just one meeting.26789
