Developing a Malaysian Psychotic Symptom Screening Inventory: an exploratory study

Psychiatric screening and diagnostic assessments in Malaysia are generally translated versions of existing tools from the West due to the lack of research on indigenous mental health concepts for diagnostic and treatment purposes. This study examined the syndromes of psychotic disorder based on Western constructs within the local context to see its applicability in Malaysia. Knowledge of this investigation would help in determining the extent of adapted tools in Malaysia with regards to validity of use. Concurrently, this study aimed to develop a Malaysian Psychotic Symptoms Screening Inventory as a primary-care-level psychiatric screener. A total of 344 respondents (174 psychotic and 170 non-psychotic respondents) were recruited. Items in the instrument were derived from commonly used Western-based inventories. The generated inventory was self-administered and data collected from the respondents were factor analysed using Principle Component Analysis. Results revealed four factors, of which three indicated significance in discriminating between non-psychotics and psychotic individuals. These factors were inconsistent with Western constructs of psychosis, suggesting that psychosis could be manifested differently in Malaysia. Further studies should focus on indigenous concepts in developing localised psychiatric screening tools.
