Validity of Activity-Based Checks (ABCs) of Pain, A Functional Pain Scale.
Article in Pain management nursing : official journal of the American Society of Pain Management Nurses, 2026. 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
purposeThe Activity-Based Checks of Pain (ABCs) is a pain assessment tool incorporating activities of daily living and instrumental activities of daily living. This instrument is designed to focus on functional capabilities and limitations due to pain. This study was designed to validate the factorial structure of the ABCs and assess its use in participants with chronic pain.
methodsParticipants were recruited in two phases. Phase one optimized the design of the ABCs, with 297 subjects selecting their preferred icon for each function and rating its understandability. The most preferred and understandable icons were then used in phase two, where 304 participants with chronic pain completed the ABCs, the Patient-Reported Outcomes Measurement Information System (PROMIS) with additional PROMIS items that were analogous to the ABCs functions but not represented in the PROMIS-29, and the Brief Pain Inventory (BPI). Data were analyzed using exploratory factor analysis and confirmatory factor analysis.
resultsFour factor loadings resulted in: multiplanar activities, sitting and/or hip flexor pain, walking and/or ambulation, and pain interference with lightweight unilateral activities. High internal consistency was demonstrated for all four factor loadings (0.623-0.879, 0.577-0.824, 0.512-0.841, 0.519-0.817, respectively). Correlations between items in the ABCs, PROMIS, and BPI resulted in moderate to strong correlations. Test-retest reliability was moderate to strong (intraclass correlation coefficient: 0.74).
conclusionsThe results confirm the ABCs as a valid and reliable tool for assessing the impact of pain on function in patients with chronic pain.
