Household Nutrition Security Scale (HNSS): Further Establishing Validity and Reliability in a Statewide Sample in Massachusetts.
Article in The Journal of nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundOne of the first survey measures for assessing nutrition security in the United States is referred to as the Household Nutrition Security Scale (HNSS). Although the analyses conducted in the original HNSS development study supported the validity and reliability of the scale, some survey development steps were beyond the scope of the original study, such as confirmatory factor analysis (CFA) and differential item functioning (DIF).
objectivesThis study aims to conduct CFA and DIF analyses on the HNSS within a new statewide sample in Massachusetts.
methodsFrom November 2022 to January 2023, the Greater Boston Food Bank and Mass General Brigham conducted a cross-sectional, statewide, representative survey of Massachusetts adults. In addition to other topics, respondents answered questions about sociodemographics and completed the HNSS. To assess CFA model fit, the Satorra-Bentler scaled chi-squared test, root mean square error of approximation (RMSEA), standardized root mean square residual (SRMR), and the Bentler Comparative Fit Index (CFI) were calculated. Cronbach's alpha was calculated to assess internal consistency. The Cochran-Mantel-Haenszel procedure was used to investigate DIF across demographic groups.
resultsParticipants in the analytic sample (n = 2903) were mostly at or under age 54 (60.7%), women (58.0%), non-Hispanic White (71.3%), and with household incomes <$75,000 (71.1%). CFA model fit metrics were well within thresholds for adequate model fit [chi-square 5.213 (Degrees of freedom (DF) = 2, P = 0.074), RMSEA = 0.024 (95% confidence interval: 0.000, 0.049), SRMR = 0.006, and CFI = 0.999]. Cronbach's alpha was 0.923. There was no indication of DIF for any of the 4 items across groups for age, race/ethnicity, gender, educational attainment, income, having children in the household, or household size.
conclusionsThese findings further support construct validity and reliability of HNSS, and the further use of the scale for research and program evaluation purposes within sociodemographically diverse samples of households.
