Brief summary
The goal of this proposal is to develop and evaluate patient-centered care tools for autistic adults and their primary care providers (PCPs).
Detailed description
The goal of this study is to develop and evaluate patient-centered care tools for autistic adults and their primary care providers (PCPs). One tool will allow autistic adults and/or their supporters to provide individualized information to PCPs about how being on the spectrum affects their healthcare and possible strategies to facilitate quality care. Another tool will capitalize on the power of patient narrative to educate PCPs about autism. These tools and other resources will be housed on an interactive website for autistic adults, supporters, and PCPs. The research team will evaluate the feasibility and acceptability of using the new web-based patient-centered care tools with autistic adults and their primary care providers. This study will provide data for a future trial testing the effectiveness of these tools in improving the health of autistic adults by increasing patient-centered care and patient activation.
Interventions
Patient participants will be given access to the toolkit and will create a customized report for their provider. Team will send report to providers and ask them to schedule appointment with patient to discuss.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Patient Satisfaction | 1 month after use of toolkit | Autistic participants completed an online survey about their satisfaction with the tool, including if they feel the tool is useful, how they think the tool will affect their healthcare, if and how they plan to use it with providers, and if they would recommend it to others. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Provider Satisfaction | 1-2 months after patient uses toolkit | Providers participated in a brief survey to assess satisfaction with the toolkit. Items addressed overall satisfaction and if they would or would not use the tools with other patients. |
| Patient Use of Toolkit Components | 1 month after use of toolkit | We collected data on whether or not participants completed the Autism Healthcare Accommodations Tool (AHAT) survey and whether or not they allowed the research team to send a copy of the report to their primary care provider. |
| Change in Patient Satisfaction With Healthcare | before and 1 month after use of toolkit | Patients completed an 8-item instrument assessing satisfaction with their primary healthcare experiences. The scale was previously adapted from the 2007 Health Information National Trends Survey (HINTS). In the pre-intervention survey autistic participants were asked to think about their last visit with their primary care provider. We did not assess patient-provider communication for those who were participating via a proxy as we did not feel that a proxy could adequately rate how satisfied the patient was with communication. Only autistic participants who said they had seen their PCP since using the healthcare toolkit were re-asked these items in the post-intervention survey. Responses used a 5-point Likert scale with anchors of 1 - Strongly Disagree to 5 - Strongly Agree. We analyzed items by summing the responses into a composite score (range 8-40; higher scores indicate higher satisfaction). Cronbach's alpha = 0.92. |
| Change in Patient's Perceived Barriers to Healthcare | Before and 1 month after use of toolkit | Autistic participants were presented with a list of 16 barriers to healthcare and asked which ones keep them from obtaining good care. We compared the total number of barriers endorsed by participants in the pre- and post-intervention surveys. The proxy version of the survey included a few modified items to differentiate between barriers faced by the autistic individuals and those faced by the supporter. Due to differences in the wording, we could not combine results from those who participated directly with those who participated by proxy. Only data from autistic adults who participated directly is shown. |
| Change in Patient Healthcare Self-Efficacy | Before and 1 month after use of toolkit | Autistic participants completed a 21-item healthcare self-efficacy scale before and 1 month after use of the toolkit. The scale was created de novo for this study, based on our prior qualitative work. Items addressed aspects related to healthcare navigation (e.g. How confident are you that you can make an appointment with your healthcare provider when needed?), successful interactions with providers, (e.g. How confident are you that you can describe your symptoms or healthcare concerns to your provider?), and self-management (e.g. How confident are you that you can take medications the way you are supposed to take them?). Response options used a 4-point Likert scale with anchors of 0 - Not at all confident to 3 - Totally confident. We scored self-efficacy by adding responses from the 21 items, resulting in a possible range of 0 to 63, with higher scores corresponding to higher self-efficacy. Cronbach's alpha was 0.92. |

Participant flow
Recruitment details
We recruited autistic adults via fliers, postings, and announcements targeted to autism and disability-related list-serves, organizations, and forums. We invited the autistic adult's primary care providers (PCPs) to participate if the patient gave permission for us to contact their provider and provided usable contact information.
Pre-assignment details
The total number of participants enrolled includes everyone who consented to participate. Some participants clicked yes to the online consent, but did not participate in the initial survey. The number of participants noted as Started in the Participant Flow module includes only those that took the initial survey.

Change in Patient Healthcare Self-Efficacy
Autistic participants completed a 21-item healthcare self-efficacy scale before and 1 month after use of the toolkit. The scale was created de novo for this study, based on our prior qualitative work. Items addressed aspects related to healthcare navigation (e.g. How confident are you that you can make an appointment with your healthcare provider when needed?), successful interactions with providers, (e.g. How confident are you that you can describe your symptoms or healthcare concerns to your provider?), and self-management (e.g. How confident are you that you can take medications the way you are supposed to take them?). Response options used a 4-point Likert scale with anchors of 0 - Not at all confident to 3 - Totally confident. We scored self-efficacy by adding responses from the 21 items, resulting in a possible range of 0 to 63, with higher scores corresponding to higher self-efficacy. Cronbach's alpha was 0.92.
Time frame: Before and 1 month after use of toolkit
Population: Participants completing pre- and post-intervention survey themselves (not via a supporter), who had complete data on the self-efficacy scales on both surveys.
| Arm | Measure | Group | Value (MEAN) | Dispersion |
|---|---|---|---|---|
| Autistic Adults | Change in Patient Healthcare Self-Efficacy | Baseline healthcare self-efficacy score | 37.92 units on a scale | Standard Error 1.21 |
| Autistic Adults | Change in Patient Healthcare Self-Efficacy | Follow-up healthcare self-efficacy score | 39.37 units on a scale | Standard Error 1.19 |
Change in Patient Satisfaction With Healthcare
Patients completed an 8-item instrument assessing satisfaction with their primary healthcare experiences. The scale was previously adapted from the 2007 Health Information National Trends Survey (HINTS). In the pre-intervention survey autistic participants were asked to think about their last visit with their primary care provider. We did not assess patient-provider communication for those who were participating via a proxy as we did not feel that a proxy could adequately rate how satisfied the patient was with communication. Only autistic participants who said they had seen their PCP since using the healthcare toolkit were re-asked these items in the post-intervention survey. Responses used a 5-point Likert scale with anchors of 1 - Strongly Disagree to 5 - Strongly Agree. We analyzed items by summing the responses into a composite score (range 8-40; higher scores indicate higher satisfaction). Cronbach's alpha = 0.92.
Time frame: before and 1 month after use of toolkit
Population: Autistic adults who participated directly (not via a proxy) and who saw their provider in the 1 month between when they participated in the baseline assessment and they completed the post-intervention survey.
| Arm | Measure | Group | Value (MEAN) | Dispersion |
|---|---|---|---|---|
| Autistic Adults | Change in Patient Satisfaction With Healthcare | Baseline Satisfaction | 30.91 units on a scale | Standard Error 0.978 |
| Autistic Adults | Change in Patient Satisfaction With Healthcare | Post-intervention satisfaction | 32.63 units on a scale | Standard Error 1.01 |
Change in Patient's Perceived Barriers to Healthcare
Autistic participants were presented with a list of 16 barriers to healthcare and asked which ones keep them from obtaining good care. We compared the total number of barriers endorsed by participants in the pre- and post-intervention surveys. The proxy version of the survey included a few modified items to differentiate between barriers faced by the autistic individuals and those faced by the supporter. Due to differences in the wording, we could not combine results from those who participated directly with those who participated by proxy. Only data from autistic adults who participated directly is shown.
Time frame: Before and 1 month after use of toolkit
Population: Participants completing the pre and post-test themselves (not via a supporter).
| Arm | Measure | Group | Value (MEAN) | Dispersion |
|---|---|---|---|---|
| Autistic Adults | Change in Patient's Perceived Barriers to Healthcare | Mean number of barriers at baseline | 4.07 number of barriers | Standard Error 0.25 |
| Autistic Adults | Change in Patient's Perceived Barriers to Healthcare | Mean number of barriers at follow-up | 2.82 number of barriers | Standard Error 0.19 |
Patient Use of Toolkit Components
We collected data on whether or not participants completed the Autism Healthcare Accommodations Tool (AHAT) survey and whether or not they allowed the research team to send a copy of the report to their primary care provider.
Time frame: 1 month after use of toolkit
| Arm | Measure | Group | Value (NUMBER) |
|---|---|---|---|
| Autistic Adults | Patient Use of Toolkit Components | Proportion completing AHAT | 96.00 percentage of participants |
| Autistic Adults | Patient Use of Toolkit Components | Proportion who requested AHAT be sent to provider | 57.74 percentage of participants |
Provider Satisfaction
Providers participated in a brief survey to assess satisfaction with the toolkit. Items addressed overall satisfaction and if they would or would not use the tools with other patients.
Time frame: 1-2 months after patient uses toolkit
Population: Participants' primary care providers. Primary care providers were included in the study to assess their impression of the toolkit, but all other outcomes (e.g. change in barriers, self-efficacy, or satisfaction with healthcare) only apply to the autistic participants, not their primary care providers.
| Arm | Measure | Group | Value (NUMBER) |
|---|---|---|---|
| Autistic Adults | Provider Satisfaction | Proportion rating AHAT as moderately or very usefu | 82.05 percentage of PCPs |
| Autistic Adults | Provider Satisfaction | Proportion who would recommend AHAT to patients | 86.49 percentage of PCPs |
