The nurse-researcher is preparing to obtain informed consent from volunteers who wish to participate in a study of nutrition and eating behaviors. The population of interest is adolescent girls aged 13 to 17 years of age who have been hospitalized repeatedly for eating disorders. Which informed consent procedure is most likely to allow the researcher to obtain the maximum number of subjects in an ethical and legal manner?
The fathers of the teenaged subjects should be asked to sign the informed consents since the father usually has custodial power.
The mothers and fathers should both be asked to sign the informed consents due to the high level of risk that study subjects must assume.
The adolescent girls should not be asked for consent since they are minors, so verbal consents from the mothers should be obtained.
The adolescents and one guardian should be asked to sign the informed consents to ensure full legal disclosure of all risks and benefits.
The Correct Answer is D
A. Assuming the father usually has custodial power may not be accurate and excludes the adolescent’s assent.
B. Requiring both parents to sign may unnecessarily limit participation, especially if one parent is unavailable.
C. Not asking adolescents for consent ignores their right to assent and involvement in decisions affecting them.
D. Ethical guidelines require obtaining assent from minors and consent from a guardian, ensuring both legal and ethical protection while maximizing subject inclusion.
