Abstract

Serious concerns have arisen in recent years regarding the unethical and illegal practices resorted to during clinical trials. Clinical trials in psychiatry are further complicated by issues such as 'validity of consent' and 'decision making capacity' of patients. This study was planned to explore the factors determining patient participation in clinical trials. A random sample of 123 consenting psychiatry inpatients were provided the information and consent-form of a hypothetical clinical drug trial. They were interviewed regarding their decision, the decision maker and factors that led to the decision. Family members tended to be the decision makers when patients were females, had low-income, were from rural background or had severe illnesses. Anticipated side effects and not wanting to interfere with existing treatment were the common reasons for refusal to participate while hope of betterment of the patient and benefit to humanity were cited for consent. The educated, urban, affluent class had more awareness regarding unethical trials and tended to be mistrustful of the medical community leading to higher rates of non-participation. Those who were adherent with ongoing treatment were also unwilling to participate. The lesser educated, low-income patients and rural domicile patients on the other hand had lesser awareness regarding clinical trials, trusted doctors and were more likely to participate. A good doctor-patient relationship, detailed explanations and clarification regarding the study and its conduct, and building awareness regarding clinical trials among vulnerable groups is necessary to ensure a valid consent involving no coercion, removal of prejudices, and ethical conduct of trials.
