parametric analysis
A systematic examination of how different values or levels of an intervention variable affect behavior change outcomes.
Full Definition
A parametric analysis is a research methodology that systematically manipulates specific parameters or dimensions of an intervention to determine their optimal values for producing desired behavioral outcomes. This approach involves testing different levels, intensities, durations, or schedules of an intervention variable while holding other factors constant. Parametric analyses are crucial for developing efficient, evidence-based interventions by identifying the minimum effective dose or the most cost-effective treatment parameters. This methodology helps clinicians make informed decisions about intervention intensity and duration based on empirical data rather than arbitrary choices.
Usage
Usage note: Focus on the systematic manipulation aspect and distinguish from component analyses that examine which parts work.
