A Pilot Study of Smartphone-Based Memory Bias Modification and Its Effect on Memory Bias and Depressive symptoms in an Unselected Population

AbstractMemory bias modification (MBM) is a relatively new approach at targeting biased processing —a central cognitive factor causing and maintaining depression. In this pilot study we aimed to develop a smartphone-based autobiographical memory training, a novel form of MBM. A total of 153 unselected participants were randomly allocated to one of three experimental training conditions (positiv e, negative or sham memory training) conducted over a period of three days. Autobiographical memory bias and depressive scores were assessed pre- and post-training, whilst recent event recall and explicit self-referent memory bias were assessed post-training. Positive memory bias significantly incre ased in the positive training condition, however memory bias did not significantly differ post-training between the three conditions. Participants who received positive training recalled a positive autobiographical event more frequently compared to the other conditions. No significant difference bet ween conditions was found in the other outcomes, including symptoms. The novel smartphone-based MBM intervention seems apt to affect autobiographical memory of emotional material. Future research should explore its possible (therapeutic) application.
