The five ethical principles involved with psychological research are beneficence and nonmaleficence, fidelity and responsibility, integrity, justice, and respect for people's rights and dignity. These principles must be strictly observed in all legitimate psychological testing, as stated by the American Psychological Association.
The first ethical issue involved in psychological testing, beneficence and non-maleficence, is to do no harm. The second, fidelity and responsibility, is to uphold professional and scientific standards of conduct at all times. The third, integrity, is to promote accuracy, honesty and truthfulness in research. The fourth, justice, requires that any benefit derived from psychological testing be made available to anyone. The fifth, respect for people's rights and dignity, requires that psychologists honor the dignity of all individuals, including a right to privacy and confidentiality.
