Internet-based guided self-help shows limited effectiveness for mild panic symptoms overall. However, individuals who completed the program experienced significant clinical benefits, suggesting potential efficacy with higher adherence.

Area of Science:

  • Psychiatry
  • Psychology
  • Digital Health

Background:

  • Internet-based guided self-help interventions are effective for panic disorder.
  • Their efficacy for milder panic symptoms remains under investigation.

Purpose of the Study:

  • To evaluate the effectiveness of "Don't Panic Online," an internet-based, cognitive behavioral, guided self-help course for mild panic symptoms.
  • The course included email guidance from therapists.

Main Methods:

  • A pragmatic randomized controlled trial (N=126) compared the intervention to a waiting-list control.
  • Participants had mild panic symptoms (PDSS-SR score 5-15) and no suicide risk.
  • Outcomes were measured online at baseline and 12 weeks.

  • Intention-to-treat analyses showed no significant panic symptom reduction.
  • Completers-only analyses indicated a moderate effect size favoring the intervention (Cohen's d=0.73).
  • Low completion rates (27% finished >=4/6 lessons) and high nonresponse (42.1%) were observed. Comorbid anxiety and depression were common.

Conclusions:

  • The internet-based guided self-help course was largely ineffective for individuals with mild panic symptoms.
  • Clinical benefits were observed among intervention completers, highlighting the importance of adherence.
