In aim of the informed consent process is

In a research, informed consent
defines as human subjects are well informed about the study. According to Armiger:
“it means that a person knowingly, voluntarily and intelligently, and in a
clear and manifest way, gives his consent” It is an ethical and legal
requirement in research on human subjects. The process to obtain consent
including the potential subjects are well informed about their rights, the
reason why the study  is conduct, all the
procedures process, possible risks and advantages of participation, expected period
of study, extent of privileged of self-identification and demographic data,
hence the participation of potential subjects in the study are entirely
willing. The aim of the informed consent process is to deliver adequate information
to potential subjects, in easy to understand language so that the subjects can make
voluntary decision about taking part in the study. To get a signature on a consent
document is essential, but it is one step in the constant process of informed
consent and not just about signing a form. With signing informed consent, it
show subjects having and understanding of the potential risks and advantages to
their participation and entirely knowing that they do not have to willing and
can quit at any time. It is important that consent forms must be written in
plain language so that subjects easily understand. The consent form must be always
reviewed and if there any changes in the study that can affect the subjects,
hence additional information will improve the consent process.

There are a few issues in informed
consent process. With assuming individual who signs the consent form does so
with full comprehension of what is present on the consent form. However, level
of understanding one person to another person is different and no other method
to measure it, hence misunderstanding of information given can occur. It is
because might be inaccurate or insufficient language translations. The responsible
of researcher become more when a study is carry out in multilingual subjects.

The informed consent process
intend to give every human subjects the right to choose whether to participate
or not in the study. Sometimes the decision for participating in research
projects is influenced by the religious belief. It is because sometimes methodology
of the research comes into conflict with the regulation of behavior set by a
subject’s religion.

Subject’s false expectation
of the research outcome is another of issues in informed consent process due to
misunderstanding. Some subject’s worry of being treated as ‘experimental model’
for the study while others decline to participate because of misconduct known
to them.

Subject perception when
participate in research will put extra burden on them and believed will give extra
work to answer questionnaire and so on. To get informed consent from them is
most difficult.

As a conclusion, although surround
by obstacle, informed consent is an important step in research. Informed
consent must completely sought otherwise no research activity involving human
subjects can be carry out and continued.
