Purpose. This article aims to analyze the forms of verbal language dysfunction in patients with schizophrenia and their relative dominance, thereby identifying factors influencing these differences in dominance. Methods. This study used data from verbal interactions with schizophrenia patients in the residual and hebephrenic phases who were treated at two psychiatric hospitals, namely RSJ Prof. H.B. Saanin, Padang, and RS Dr. Soeharto Heerdjan, Jakarta. These two hospitals represent the contexts of regional and urban areas. The data were analyzed using theories of language dysfunction in psycholinguistics by Andreasen, Nugroho, as well as the semantic theory by Cruse. Result. The results of the study show ten forms of verbal language dysfunction in patients with schizophrenia, namely incoherence, blocking (Hemmung), Sperrung, neologism, repetition, word salad, and language anomalies including improbability, dissonance, and pleonasm. The most dominant form of verbal language dysfunction in both hospitals was incoherence. In addition, improbability was more noticeable at RSJ Prof. H.B. Saanin, while neologism was more dominant at RS Dr. Soeharto Heerdjan. This difference in dominance is influenced by patients’ social, environmental, and linguistic backgrounds. Conclusions. Verbal language dysfunction in patients with schizophrenia is not only linked to thought disorders but also shows problems in semantic, lexical, and grammatical systems, influenced by social, environmental, and linguistic contexts across different hospital settings and communication environments. Based on these findings, further research is recommended to develop a clinical corpus-based linguistic database containing transcriptions, dysfunction categories, linguistic descriptions, and case examples analyzed by psychologists and psychiatrists. This database development is expected to facilitate a more comprehensive mapping of the relationship between language dysfunction patterns, treatment duration, and the type and dosage of pharmacotherapy. Thus, it can serve as the starting point for a linguistics-based treatment prototype for schizophrenia patients, involving experts from the psychiatry community. This prototype can then be tested through implementation on a sample of patients in a psychiatric hospital. The prototype can then be implemented in psychotherapy practice. Therefore, this research will significantly impact the development of rehabilitation models for schizophrenia patients in the future.
