New research involving Oxford researchers has shown that a simple digital intervention that includes gameplay can dramatically reduce intrusive memories of trauma in a month, even to the point of being symptom-free after six months. This treatment was also very effective at reducing the symptoms of post-traumatic stress disorder (PTSD) more generally. The findings have been
how is this digital treatment similar to BetterHelp? how would it possibly be bad in factors other than efficacy, like BetterHelp was due to data nightmares and advertising a different mechanism? this isn’t even online
99 is a more than enough sample size if your RCT’s Bayes factor is 114 and 15.8 for better efficacy than -control and -regular treatment respectively, which corresponds to “extreme” and “strong evidence” (Lee and Wagenmakers 2013, p. 105; adjusted from Jeffreys, 1961). The Lancet also peer-reviewed the claim “The Bayesian adaptive trial design enabled efficient evaluation with early stopping when convincing evidence was reached (n=99).[2]”
indeed further testing is needed to establish subgroup effects and improve generalizability but this is already quite promising
