This paper provides a checklist of 10 potential ethical problems associated with intervention in families through home-based programs. Problems which directly involve program participants are (1) pressure on parents to join the program, (2) violation of confidentiality, (3) intrusiveness, (4) need to respect the family's style of living, (5) giving assistance in matters beyond the home visitor's areas of expertise, and (6) giving more services than the home visitor can deliver and more than the participants want. The last four ethical considerations pertain to the ethics of program evaluation: the need for definitions of goals and method; for monitoring the quality of delivering the method; and for systematic program evaluation to provide evidence of program success.
