Decision-making process in prescribing for schizophrenia – an analysis of clinical decision making based on the theory of planned behaviour”
Although there are no recommendations for the prescribing of either typical or atypical antipsychotics for schizophrenia, it has been observed that atypical antipsychotics are prescribed for almost 66.7% of patients with schizophrenia. This has raised a key question: what are the factors affecting prescribing antipsychotics for schizophrenia. Therefore, the researcher conducted a correlational cross-sectional design to examine the factors affecting prescribing antipsychotics for schizophrenia based on the theory of planned behaviour. Counsellors were invited to respond to self-reported surveys in which they score the most important factors affecting their clinical decision making. Findings showed that there was a correlation and association between both direct subjective norms and direct and intention to prescribe antipsychotics for schizophrenia. On the other hand, there was no significant correlation between perceived behavioural control and generalised intention or intention statement to prescribe antipsychotics for schizophrenia. This study concluded that direct subjective norms and direct attitudes can be strong predictors of prescribing antipsychotics for schizophrenia. However, the study showed that there is a need to conduct studies with longitudinal design because the correlational design cannot prove cause and effect. Also, it is necessary to conduct further study, which takes the reliability between direct and indirect measures into consideration in order to address the issue of bad construct validity in the indirect measures used in this study.
