Validation of a single question for assessment of habitual physical activity in women.

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
backgroundAccurate assessment of physical activity behaviors allows clinicians to target counseling more effectively. Single questions regarding habitual physical activity provide the most feasible option for rapid physical activity assessment. This study evaluated construct validity of a single item physical activity question to self-report habitual activity as simple categorical descriptors (not active, somewhat active, active, very active).
methodsWomen (N = 120) completed one laboratory session for measurement of self-reported physical activity (International Physical Activity Questionnaire-IPAQ), anthropometrics and body composition, and physical activity-related quality of life (SF-36 physical function subscale, Vitality Plus Scale). Construct validity was evaluated as convergent and known-groups validity.
resultsMean age was 60 ± 16 years (range 25-89). The majority (62%) reported being active or very active. Age was not significantly related to activity levels. Correlation analysis demonstrated good convergent validity. Significant negative correlations were found with body weight, body mass index (BMI), waist circumference, and body fat (all p <0.001). Significant positive correlations were found with vigorous intensity activity (p <0.001), moderate intensity activity (p = .004), walking (p = .005), and quality of life (p <0.001). Good known-groups validity was demonstrated by significant differences between habitual physical activity levels for body weight, waist circumference, body fat, vigorous intensity activity (all p <0.001), moderate intensity activity (p = .038), walking (p = .049), and quality of life (p <0.001). Regression models confirmed known-groups validity.
conclusionsA single question with categorical descriptors is valid for brief clinical assessment of habitual physical activity in women across a wide age range.
