In this database, the authors shared the raw experimental data associated with the article: Effectiveness of a Metacognitive Intervention for Schizophrenia (MCI-S) Program for Symptom Relief and Improvement in Social Cognitive Functioning in Patients with Schizophrenia. Data document is General characteristics of the homogeneity test before the implementation of the MCI-S program, and data on the main psychotic symptoms, social functioning, and social cognitive survey before, after, and 4 weeks after the implementation of the MCI-S program.

The program, Metacognitive Intervention for Schizophrenia (MCI-S), was developed by revising and complementing Metacognitive Training (MCTain) and Metacognitive Therapy (MCTherp) (Moritz & Woodward, 2007; Wells, 2011). The effectiveness of the MCI-S program was evaluated with regard to symptom relief and functional improvement in patients with schizophrenia. Measures 1. Psychotic symptoms Psychotic symptoms were measured using the Korean version of the Psychotic Symptom Rating Scale, which was translated by Jung et al. (2007). This measure has 17 items: 11 items assess auditory hallucinations, and six items assess delusions. Items are responded to using a 5-point Likert scale (scored 0–4). Higher scores indicate more severe psychotic symptoms. In this study, Cronbach's α was .95 and .93 for the same subscales, respectively. 2. Personal and social performance The Personal and Social Performance (PSP) Scale was developed by Morosini, Magliano, Brambilla, Ugolini, and Pioli (2000) and assesses the extent to which aspects of personal and social functioning are being affected by psychopathology. This study used the Korean version standardized by Lee et al. (2006). Four dimensions are assessed by the scale: difficulty in socially useful activities including work and school, personal and social relationships, disability level including self-care, and disturbing and aggressive behaviors. Each dimension consists of a single question that is responded to using a six-point scale (from “No symptoms” to “Very severe”). A total score can be derived that ranges from 1–100. Higher scores indicate a higher degree of severity in PSP. In the present study α = .76. 3. Insight Insight was measured using the Korean version of Beck’s Cognitive Insight Scale (Beck, Baruch, Balter, Steer, & Warman, 2004) that was translated by Kim (2006). This tool consists of 15 items: nine items on self-reflection and six items on self-certainty. Items are responded to using a four-point Likert scale. The score is derived by subtracting the score for self-certainty from the self-reflection score; higher scores indicate greater cognitive insight. In the present study, Cronbach's α was .82. 4. Social cognition Social cognition was measured with the Hinting Task developed by Corcoran, Mercer, and Frith (1995). The translated Korean version of the questionnaire that was created by Hur et al. (2006) was used in the present study. This tool is a self-report questionnaire devised to test the ability to infer the real intention that is concealed in an indirect discourse. The Korean version of the Hinting Task consists of eight questions. Higher scores indicate higher social cognition. Cronbach's α = .89 in this study.
