Diabetes prevention programs (DPPs) targeting dietary and physical activity behaviour change have been shown to decrease the incidence of type 2 diabetes; however, a more thorough reporting of intervention characteristics is needed to expedite the translation of such programs into different communities. In this scoping review, we aim to synthesize how DPPs are being reported and implemented. A scoping review using Arkey and O’Malley methods was conducted in accordance with the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analysis. MEDLINE, CINAHL, PsycINFO, EMBASE, and SPORTDiscus were searched for studies relating to diabetes prevention and diet/exercise interventions. Only studies delivering a diet/exercise intervention for adults identified as “at risk” for developing type 2 diabetes were included. The Template for Intervention Description and Replication (TIDieR) was used to guide data extraction, and each DPP was scored on a scale from 0 to 2 for how thoroughly it reported each of the items (0 = did not report, 2 = reported in full; total score out of 26). Of the 25,110 publications screened, 351 (based on 220 programs) met the inclusion criteria and were included for data extraction. No studies comprehensively reported on all TIDieR domains (mean TIDieR score: 15.7 of 26; range 7 to 25). Reporting was particularly poor among domains related to “modifications,” “tailoring,” and “how well (planned/actual).” "How well (planned)" assesses the intended delivery of an intervention, detailing the initial strategies and components as per the original design, whereas "how well (actual)" evaluates the extent to which the intervention was executed as planned during the study, including any deviations or modifications made in practice. Although there is evidence to suggest that DPPs are efficacious, a more thorough reporting of program content and delivery is needed to improve the ability for effective programs to be implemented or translated into different communities. Il a été démontré que les programmes de prévention du diabète (PPD) axés sur les changements de comportement en matière d’alimentation et d’activité physique permettent de diminuer l’incidence du diabète de type 2. Toutefois, des comptes rendus exhaustifs sur les caractéristiques de l’intervention sont nécessaires pour accélérer la transposition de ces programmes au sein des diverses collectivités. La présente étude de portée vise à faire la synthèse sur la façon dont l
