The development and validation of a self-reinforcement scale for repeated blood donation.
Article in BMC psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The current study aimed to develop and validate a self-reinforcement scale for repeated blood donation (SRS-RBD). In Study 1, six items were created, and the factor structure of SRS-RBD was explored among 155 Chinese student blood donors. In Study 2, SRS-RBD was validated among 164 donors. In Study 3, a total of 850 blood donors were invited to participate in an online-survey measuring SRS-RBD at baseline, and their RBD behavior was captured 6 months later. A two-factor structure of SRS-RBD was established in Study 1 and further validated in Study 2 and Study 3. The SRS-RBD demonstrated satisfactory reliability and validity. A cut-off score of 20 was suggested as having the best performance to identify donors who had a high chance to re-donate. The SRS-RBD can be considered reliable in measuring the self-reinforcement of RBD among blood donors. The scale may be a useful tool in blood donation practice and research programs.
