Abstract:
Mental Time Travel (MTT) is the ability of individuals to project themselves to the past or to the future. Studies have shown that schizophrenia (SZ) patients are impaired in MTT. The present study aimed to examine whether MTT in patients with SZ can be improved through Life Review Therapy. Fifty patients with SZ were randomly assigned to the training (SZ-training) or control (SZ-control) group. Whereas the SZ-training group received four-week Life Review Therapy in addition to conventional treatment, the SZ-control group only received conventional treatment. MTT, emotional status, life satisfaction and cognitive functions were assessed before and after the training. We also recruited 25 matched healthy controls to complete all the assessments at baseline. After training, the SZ-training group showed higher specificity and more field perspective than the SZ-control group. No significant difference was found between the SZ-training group post-training assessment and the healthy controls. The SZ-training group also showed significant improvements in emotional expression, semantic memory and verbal fluency, but the SZ-control group did not show such improvements. These results indicated that Life Review Therapy is effective in improving MTT of SZ patients.
