The Phase V® Treatment Satisfaction modules were developed independently by Phase V Technologies using a compendium of existing treatment satisfaction items and incorporating new items developed from a series of focus group studies with persons with various diseases and conditions and experienced with different treatment regimens. Item pool selection, psychometric analysis, and field-testing was conducted by Phase V Technologies.
Treatment Satisfaction
Although the modules are disease- and condition-specific, the following constructs typically apply across all the board assessing the regimen burden, effectiveness and overall net benefit from the patient’s perspective:
- Life Interference
- Convenience
- Burden
- Acceptance of Negative Aspects (including side effects, stress, hassle)
- Acceptance of Positive Aspects (including effectiveness, ease of use, comfort)
- Overall Patient Preference (compared to other treatments).
