An internet-based intervention for people with psychosis (EviBaS): Study protocol for a randomized controlled trial
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-13)<p><i>Background</i>: Evidence shows that internet-based self-help interventions are effective in reducing symptoms for a wide range of mental disorders. To date, online interventions treating psychotic disorders have been scarce, even though psychosis is among the most burdensome disorders worldwide.

Prolonged rather than hasty decision-making in schizophrenia using the box task. Must we rethink the jumping to conclusions account of paranoia?

For the first time, the box ... -
A randomized controlled trial on a smartphone self-help application (Be Good to Yourself) to reduce depressive symptoms
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-29)Depressive symptoms are common, yet only a subgroup of individuals receive adequate treatment. To reduce the treatment gap, several online self-help programs have been developed, yielding small to moderate effects. We developed a smartphone self-help application addressing depressive symptoms. We sought to evaluate its feasibility and efficacy in participants reporting a subjective need for help (a ... -

Precursors, such as sleep problems or worrying, predict these fluctuations. To date, it remains unclear whether the same precursors predict symptom variability also during treatment in an online intervention for psychosis, ...
