Objective:
To determine whether participants preferred a provider-completed or self-reported antenatal psychosocial health assessment (ALPHA) form, to evaluate the forms' effectiveness in facilitating disclosure of psychosocial issues, and to determine whether different providers gathered different information.
Design:
Randomized controlled study.
Setting:
Offices of family physicians and public health nurses (PHNs) in three health regions on Prince Edward Island.
Participants:
Physicians, PHNs, and 76 pregnant women.
Interventions:
Participants completed one form and a questionnaire on theirexperience. Providers were also interviewed.
Main Outcome Measures:
Suitability and effectiveness of the forms and frequency of issues disclosed by type of form and provider.
Results:
Most participants would recommend routine use of the ALPHA form for all pregnant women. Of the 238 psychosocial issues disclosed, significantly more were disclosed to physicians than to PHNs.
Conclusion:
Both forms were acceptable to women and providers (no clear preference emerged) and were effective at gathering information. Physicians gathered significantly more information than PHNs.
