Aims: The purpose of this study is to pilot test the feasibility and preliminary efficacy
of healthcare provider referrals to a tax filing app within parental-child health
programs whether such referrals can increase receipt of tax credits among low-income
parents. The study will use a single-group, pre/posttest design. The primary outcome is
feasibility, defined as whether or not participants filed taxes after referral. Secondary
outcomes are acceptability of the app and preliminary efficacy of the app on improved
parent and child health. Specific aims are to:
assess frequency of tax filing among parents referred to a tax filing app (Primary
outcome/Feasibility)
explore pre/posttest changes to parent and child health after referral (Secondary
outcome/Preliminary efficacy).
Design: This pilot study will use a single-group, pre/post-test design to assess the
feasibility and preliminary efficacy of healthcare provider referrals to a tax filing
app.
Intervention: Referrals to a tax filing app
Setting: The setting for this study is maternal/child health programs and clinics in Los
Angeles.
Sample: The target population is parents making less than $75,000 per year in income .
Parents will be eligible to participate in the study if they are within the income
threshold, have one or more children under six years of age, speak English or Spanish,
have access to an internet-enabled device (smart phone or tablet), and have a valid tax
filing ID (SSN or ITIN). Parents will be ineligible if they have already filed taxes
during the study period or are experiencing an acute mental health crisis (e.g.,
suicidality). We focus on children under six years of age because this is a critical and
sensitive developmental window when interventions have potential for outsized impact on
child health.
Procedures: Parents will be recruited during program visits/encounters early in tax
season in 2023. Those that provide informed consent to participate in the study will
complete a baseline survey and receive the assigned intervention (referral to a tax
filing app) the same day or within the same week of their program visit. Parents will
complete a follow-up survey to assess outcome measures after they receive tax refunds. A
second follow-up survey will be sent 3-6 months later (depending on time of filing, and
average time of receipt of tax credit this season) to assess medium-term outcomes.
Outcomes. We will assess the following outcomes. The primary study outcome is
feasibility; acceptability and preliminary health efficacy are secondary outcomes.
Feasibility: Self-reported tax filing (items developed for this study) Preliminary
efficacy: We will assess pre/posttest changes in the following health-related measures as
indicators of preliminary efficacy: 1a) parent overall health rating (PROMIS® Scale v1.2
- Global Health [Hays et al., 2009]; Patient Health Questionnaire- 2 [Kroenke et al.,
2003); and 1b) child overall health and developing rating (PROMIS® Early Childhood Parent
Report Global Health [Forrest et al., 2014]).
Demographic and family health background information (see survey: age, gender,
race/ethnicity, income, social determinants of health, health background, other tax
filing characteristics) will be collected to identify characteristics of the sample. In
future studies, we intend to study in greater depth the physical health outcomes that
might be sensitive to this intervention with longer-term follow up.
