In April 2006, Massachusetts passed a comprehensive health care reform bill entitled An Act Providing Access To Affordable, Quality, Accountable Health Care (Chapter 58 of the Acts of 2006), that sought to move the state to near universal coverage. In order to track the impacts of Chapter 58, the Blue Cross Blue Shield of Massachusetts Foundation began funding an annual telephone survey of nonelderly adults in the Commonwealth in fall 2006, just prior to the implementation of key elements of the law. That survey, called the Massachusetts Health Reform Survey (MHRS), was fielded in the fall of 2006-2010, 2012, 2013, 2015, and 2018. This data collection comprises data from the 2018 round of the Massachusetts Health Reform Survey (MHRS). Topics covered by the survey include health insurance status; specific types of health insurance coverage held by the survey respondents; insurance premiums and covered services for those with insurance; access to and use of health care; out-of-pocket health care costs and medical debt; health and disability status; mental health and substance use disorders. Demographic variables include income, race, and employment status.

The MHRS sample was designed by Marketing Systems Group (MSG), using the GENESYS IDplus procedures to eliminate non-working and business landline numbers from the sample. Households were selected using stratified random-digit dialing. One respondent was randomly selected from each eligible household. Uninsuredand low- and moderate-income adults were oversampled.

2019-10-24 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Checked for undocumented or out-of-range codes.

All tabulations based on the survey data were prepared using weights that adjust for the complex design of the survey, for undercoverage, and for survey nonresponse. Separate weights were constructed for the landline sample and for the combined landline and cell phone samples. The relative weights of the landline and cell phone samples for Massachusetts were determined using National Health Interview Survey estimates of the share of Massachusetts adults in households with landlines and cell phones.

The final weights were constructed from a base weight for each adult that reflects his or her probability of selection for the survey and a post-stratification adjustment to ensure that the characteristics of the overall sample were consistent with the characteristics of the Massachusetts population as projected by the U.S. Census Bureau. Specifically, the final weights include an adjustment to ensure that the age, sex, race/ethnicity, number of adults 19 to 64, and the geographic distribution of the sample are consistent with the distribution of the population in Massachusetts. This adjustment is needed since some adults are less likely than others to be included in the survey, resulting in their being under-represented in the sample. The overall design effect for the final weights (after the post-stratification adjustments) was 1.88 in the 2018 MHRS.
