The goal of this clinical trial is to understand the impact of an educational intervention on reproductive health care providers' environmental health literacy related to phthalates. The main questions to answer are:
Participants will be asked to complete three surveys: one before the educational intervention, and two after the intervention. The will be asked to complete the approximately 1-hour online educational intervention, which consists of a series of videos from the perspectives of patients, OBGYNs, and researchers, an interactive module, and a worksheet to facilitate conversation with patients.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Reproductive Health Professionals - EHL | Experimental | All participants will complete a pre-course survey, engage in the online educational intervention, then complete 2 post-course surveys. They have the option to provide urine samples before and after the intervention. |

| Online educational phthalate course | Behavioral | This is an online course focused on phthalates for reproductive health professionals. It consists of videos from patient, scientist, and OBGYN perspectives describing how phthalates relate to reproductive health. There is also an interactive module and worksheet to facilitate conversations about phthalates with pregnant individuals. |
| Measure | Description | Time Frame |
|---|---|---|
| Baseline phthalate environmental health literacy | Measure of phthalate reproductive environmental health literacy via validated scale (pre educational intervention), the Phthalate Environmental Reproductive Health Literacy (PERHL) scale. Scores on the PERHL scale range from 6-31, with a higher score indicating higher environmental health literacy. | Up to 2 weeks |
| Change from baseline phthalate environmental health literacy | Measure of phthalate reproductive environmental health literacy via validated scale (post educational intervention), the Phthalate Environmental Reproductive Health Literacy (PERHL) scale. Scores on the PERHL scale range from 6-31, with a higher score indicating higher environmental health literacy. | Up to 4 weeks |
| Sustained change from baseline phthalate environmental health literacy | Measure of phthalate reproductive environmental health literacy via validated scale (2 months post educational intervention), the Phthalate Environmental Reproductive Health Literacy (PERHL) scale. Scores on the PERHL scale range from 6-31, with a higher score indicating higher environmental health literacy. | 2 months |
| Baseline urinary biomarkers of phthalate exposure | Collected via urine samples, measure of previous phthalate exposures. We will evaluate urine samples for urinary phthalate metabolite concentrations using a standard panel, measuring 16 urinary phthalate metabolites and their replacements (CX-MINCH, MECPTP, MEHHTP, OH-MINCH, mBP, mBzP, mCnP, mCOP, mCPP, mECPP, mEHHP, mEHP, mEOHP, mEP, mNP, miBP), and assayed using a modified method from the Centers for Disease Control and Prevention. Briefly, HPLC-MS/MS ESI is conducted based on the CDC's Phthalate Metabolites in Urine Method No: 6306.03. We will also calculate the molar sums of SG-adjusted metabolites representing metabolites related to parent compound DEHP (i.e., ΣDEHP = (mEHP/278) + (mEHHP/294) + (mEOHP/292) + (mECPP/308)) and personal care product (PCP)-associated phthalates (i.e., ΣPCP = (mBP/222) + (miBP/222) + (mEP/194)). Units for all metabolites will be ng/mL. |
