This study is an integrative review of literatures of research on emotion processing in depression using facial expression stimuli.

For the review, we searched domestic and international research articles over the past 20 years according to the integrative review procedure and selected the final 19 papers.

The results of the review revealed that depressed people, compared with those who were not depressed, had the following differences. First, they needed longer time for precise processing of emotion. Second, they managed to recognize positive emotion with high intensity while easily recognized negative emotions with low intensity. Third, they tended to overestimate the intensity of negative emotion. Fourth, they showed a negative interpretation bias to ambiguous or neutral facial expressions. Meanwhile, consistent results across the studies were not found for the variable of accuracy.

Our results suggest that it is necessary to develop more elaborate intervention program and design more sophisticated experiment for further coherent understanding of depression.

The purpose of this study was to review the literature to improve the understanding of life events of early schizophrenia and identify the related factors using an integrative review.

The key words, ‘schizophrenia’ and ‘life events’ were used to search peer-reviewed evidence through six electronic databases and 11 papers were selected.

The factors related to the life events of the early schizophrenia were as follows 1) social isolation, lack of self-efficacy, lack of coping as antecedents 2) depression as a mediating factor 3) precipitating role of psychotic symptoms as a consequence.

It is difficult to identify the causal relationship between life events and psychotic symptoms because there are methodological limitations and conflicting results. In the future, it will be necessary qualitative research on life events of early schizophrenia and intervention study applying related factors identified in this study.
