Long-running surveys need a systematic way to reflect social change and to keep items relevant to respondents, especially when they ask about controversial subjects, or they threaten the items' validity. We propose a protocol for updating measures that preserves content and construct validity. First, substantive experts articulate the current and anticipated future terms of debate. Then survey experts use this substantive input and their knowledge of existing measures to develop and pilot a large battery of new items. Third, researchers analyze the pilot data to select items for the survey of record. Finally, the items appear on the survey-of-record, available to the whole user community. Surveys-of-record have procedures for changing content that determine if the new items appear just once or become part of the core. We provide the example of developing new abortion attitude measures in the General Social Survey. Current questions ask whether abortion should be legal under varying circumstances. The new abortion items ask about morality, access, state policy, and interpersonal dynamics. They improve content and construct validity and add new insights into Americans' abortion attitudes.

COVID-19 Vaccine Hesitancy Is the New Terrain for Political Division among Americans

Politically conservative Americans are less likely than those who identify as liberal to report a willingness to get a vaccine against coronavirus disease 2019. Using data from the Axios/Ipsos Coronavirus Survey from November 2020 to February 2021, the authors find that this partisan divide in vaccine hesitancy has increased over time. Recent scholarship has suggested that these differences can be attributed to personal characteristics, including varying levels of trust in institutions. The authors find that although the data supported this hypothesis in mid-November, by early February differences in demographics, concern about the pandemic, and institutional trust no longer explained the partisan gap. The authors explain the deepening divide by turning to recent evidence that political party affiliation has become a source of identity that shapes personal decision making.

Low perceived susceptibility to pregnancy as a reason for contraceptive nonuse among women with unintended births

Background: While low perceived susceptibility (PS) to pregnancy is a common risk factor for having sex without contraception among women susceptible to unintended pregnancy, little research has examined the correlates of low PS, and none have investigated whether low PS predisposes women to later pregnancy discovery and prenatal care initiation among women with unintended births.

Methods: We use data from the 2004‒2011 Pregnancy Risk Assessment Monitoring System and limit our sample to women in the United States with unintended births who were not using contraception at the time of the index pregnancy (n = 55,940). Women were classified as having low PS if they indicated they could not get pregnant at the time the index pregnancy occurred or they or their partner were sterile. We use logistic regression to identify correlates of low PS and determine whether low PS is associated with timing of pregnancy recognition and prenatal care initiation.

Results: Over one-third of women with unintended births cited low PS as a reason for contraceptive nonuse. Maternal age and disadvantage are correlated with low PS. Among women with unintended births, those with low PS had lower odds of early pregnancy recognition (adjOR = 0.88; 95% CI: 0.82, 0.94) and prenatal care initiation (adjOR = 0.86; 95% CI: 0.79, 0.94) compared to those who did not hold these beliefs.

Contribution: Although research remains focused on other barriers to contraceptive use, low perceived susceptibility to pregnancy is critical to understanding the high rates of unintended pregnancies and births in the United States and may affect prenatal health.
