How do sociologists measure adherence to Christian nationalist beliefs in surveys?
Executive Summary
Sociologists most commonly measure adherence to Christian nationalist beliefs using short multi-item scales that ask about the proper relationship between Christianity, American identity, and government; these scales are combined into an additive index and used to classify respondents into tiers such as Adherents, Sympathizers, Skeptics, and Rejecters. The methodology pioneered and widely reported by PRRI relies on a five-item battery recalibrated to a 0–1 scale with high internal consistency, while independent researchers have experimented with longer scales and latent-profile methods that produce broadly similar subgroupings but different nuances in prevalence and correlates [1] [2] [3] [4] [5].
1. How major surveys claim to capture Christian nationalism—and what they actually ask
Leading national surveys use a concise battery of attitudinal items focused on whether America should be officially Christian, whether being Christian is core to being truly American, and whether government should favor Christian values, then sum responses into a composite Christian nationalism score. PRRI’s approach, reported across several briefs and the American Values Atlas, uses five such items, reports a Cronbach’s alpha of 0.92 indicating high internal consistency, rescales scores to 0–1, and divides respondents into four empirically grounded categories—Adherents, Sympathizers, Skeptics, Rejecters—which PRRI reports in national and state-level estimates [1] [2] [3]. This short battery is the dominant public-facing operationalization and is presented as straightforward to interpret for comparative analysis.
2. Alternative measurement approaches and what they add to the picture
Other researchers have used longer scales and psychometric work to probe the construct’s dimensions, producing scales with more items that include attitudes toward outgroups, political opponents, and governance preferences; one independent 14-item study found similar proportions of Adherents and Sympathizers while also documenting links to dehumanizing views and preferences for authoritarian leadership [4]. Psychometric studies examining scale properties report on reliability and dimensionality and encourage validation beyond face items, noting that longer measures can reveal additional facets such as authoritarianism, exclusionary attitudes, and civic behaviors that short batteries may miss [6]. Recent latent-profile analyses identify comparable four-group patterns while emphasizing subgroup heterogeneity among populations like emerging religious leaders [5].
3. How researchers validate and compare these measures
Validation combines statistical indices, correlation with demographic and political variables, and replication across samples. PRRI reports high internal consistency (alpha = 0.92) and robust correlations with partisan affiliation, religious tradition, church attendance, and support for specific policies and political figures; they also validate scale cutpoints by demonstrating consistent subgroup profiles across large probability samples and multi-year waves [1] [7]. Independent psychometric work calls for attention to construct validity—showing that the scale predicts related outcomes such as political behavior, intolerance, or support for extra-legal measures—while latent-class modeling provides a complementary validation strategy that clusters respondents by response patterns rather than enforcing additive scoring [6] [5]. Together, these approaches show convergent evidence that short and longer instruments tap a meaningful social construct.
4. What the data say about who is classified as an Adherent and why it matters
Across multiple reports and re-analyses, a consistent pattern emerges: those classified as Adherents or Sympathizers are disproportionately Republican, frequent churchgoers, and concentrated among white evangelical Protestants, with higher prevalence among older and less-educated cohorts and connections to trust in far-right media outlets and affinity for strongman leadership [2] [8]. Estimates vary: PRRI’s recent work reports roughly 10–11% Adherents and 19–20% Sympathizers, producing roughly three in ten Americans who are at least sympathetic; independent studies using longer batteries produce similar aggregate shares though they report distinct correlates like civic engagement alongside exclusionary attitudes [1] [4] [9]. These demographic and media correlations are central to interpretations about political risk and social polarization.
5. Limits of current measures and where researchers should go next
Current instruments capture a coherent ideology but leave gaps: short batteries risk conflating theological identity with chauvinistic policy preferences, long scales risk overfitting, and cross-sectional surveys cannot fully disentangle causation from selection into religious and media ecosystems. Recent work recommends broader validation across populations, mixed methods to understand interpretive frames respondents use when answering, and longitudinal or experimental designs to test whether Christian nationalist sentiment predicts behavior independent of partisan cues [6] [5]. Transparent reporting of item wording, cutpoints, and sample frames is the best immediate fix to allow outside researchers and policymakers to assess how sensitive prevalence estimates are to measurement choices.
