Validity and reliability of a dietary stages of change measure among economically disadvantaged African-American adolescents.
Article in American journal of health promotion : AJHP. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeTo examine the construct validity and 2-month test-retest reliability of a staging measure for assessing readiness to consume five or more daily servings of fruits and vegetables among economically disadvantaged African-American adolescents.
designLongitudinal survey.
settingYouth services agencies serving low-income communities in New York, New Jersey, and Pennsylvania. SUBJECTS: African-American adolescents (N = 390) aged 11 to 14 years. MEASURES: Self-report measures of stage of change and fruit and vegetable consumption. ANALYSIS: Correlation analysis and analysis of covariance were used to examine, cross-sectionally, whether fruit and vegetable consumption differed by stage of change (validity assessment). Correlation analysis and Cohen's kappa (κ) were used to assess the degree of association and level of agreement between stages longitudinally (test-retest reliability assessment).
resultsFruit and vegetable consumption was moderately correlated with stage of change (r ≥ .54, p = .000). Consistent with the transtheoretical model, youths' consumption increased from earlier to later stages (p = .000). Forty-six percent of youths were in the same stage at both measurements. The correlation between stages was .26, and Cohen's κ was .20 (p = .000).
conclusionsDespite preliminary evidence of construct validity, the low test-retest reliability found suggests that further research and testing are needed to improve the stability of the measure.
