Abstract
Negative memory bias and overgeneralized memory are big risk factors for the development
and maintenance of depressive disorders. To reduce memory bias and improve mood
outcome, techniques like Cognitive Bias Modification (CBM) and Positive Memory Training
(PoMet) might be effective options. Recently, internet-based and mobile applications have
been developed using CBM and positive training methods, with positive effects on depressive
symptoms. For this study, a mobile application is developed where participants report their
positive experiences each day, in order to reduce memory bias and improve mood outcome.
However, as stress affects the retrieval of long-term memory, this could have a different effect
on the outcomes of the training app. Participants administered the DASS-21 and had to use
the app for five days, they were assigned randomly to the Positive Memory Training group
and the control group. 68 people took part in the study, from which (53 female, 15 male).
First, the positive memory training did not work: no changes in negative and positive mood
were found. Furthermore, stress was not related to positive and negative mood change during
the training. More research is needed in order to make the app effective.
