Abstract: The Theory of Planned Behavior (TPB) is the dominant psychological framework for explaining individual energy behavior, yet its predictive validity in this domain rests almost entirely on intentions or self-reported behavior, which correlate only modestly with objective measures. This exploratory scoping review, informed by the PRISMA extension for scoping reviews (PRISMA-ScR), maps how behaviour has been measured in quantitative TPB research on energy use, saving, and curtailment, and detects the specific studies that measured behavior objectively, through meters, sensors, billing or consumption records, monitored devices, or direct observation. Searches of Scopus and Web of Science identified 773 records, 467 unique records remained after deduplication and full-text assessment confirmed four eligible studies. Studies measuring energy behaviour through objective outcomes are therefore rare in the TPB literature, and where they exist, they rely either on consumption traces (records, meters, or sensors) or on coding by trained observers. A common design weakness is the inconsistency between constructs measured at the individual level and outcomes measured at the household, dormitory, or office level. Across the eligible studies, TPB constructs show weak and varying associations with objectively measured energy behavior; intention is often non-significant, while prediction improves when behavior is verified in real time against consumption traces. These findings are preliminary, as screening of the records whose abstracts did not state the measurement method is ongoing. Testing whether the theory explains energy behavior rather than self-reports, requires designs that pair person-attributable objective outcomes with full TPB measurement.
