This thesis is concerned with the relationship between cognitive impairment and everyday functioning in schizophrenia from a clinical perspective.  More specifically, the thesis examines (1) the relationship between deficits in social cognition and performance in daily life and (2) the extent to which everyday functioning can be improved by cognitive rehabilitation.

First, a selective overview of literature on cognitive limitations in schizophrenia is given, together with a more extensive review of literature on social cognition. Also, the thesis includes two cross-sectional studies on social cognition in schizophrenia. The first study demonstrates that the perception of emotional prosody (= emotional intonation of speech) and especially the perception of negative emotions is impaired in people with schizophrenia.
The second study shows that emotion perception and Theory of Mind are important predictors of community functioning in schizophrenia.

Second, literature on cognitive rehabilitation in schizophrenia is reviewed. Thereafter, the efficacy of a cognitive prosthesis in the form of SMS-text messages is evaluated, first in a series a case-studies and subsequently in a larger scale controlled study. SMS-text messages are used the prompt goal-behaviour that is chosen by the patients themselves. Results show that prompting significantly enhances the percentage of achieved goals in daily life. When goals are subdivided into categories, we see that prompting leads to an increases in appointments with mental health workers that are attended and in leisure activities. Medication adherence and attendance at the training program did not increase with prompting.
