suddengains

suddengains identifies sudden gains in longitudinal datasets to quantify large, stable improvements between consecutive outcome measurements in psychological and behavioral intervention studies and is implemented as an R package.

Key Features:

• Automation: Automates the application of the three traditional criteria for identifying sudden gains across longitudinal assessments.
• Customization: Supports customization to incorporate methodological adaptations of the standard sudden-gain criteria.
• Descriptive statistics and data export: Calculates descriptive statistics and enables export of data files for further analysis.
• Reproducibility and reporting: Standardizes the application of criteria to improve reproducibility and reporting of sudden-gain analyses.
• Research efficiency: Facilitates consistent and efficient identification of sudden gains to support research on individual change processes.

Scientific Applications:

• Psychology and behavioral sciences: Detects sudden gains in repeated-measures outcome data to study individual change processes in psychological and behavioral intervention research.
• Longitudinal assessment analysis: Applies to longitudinal datasets with multiple assessments to quantify large, stable improvements between consecutive measurements.

Methodology:

Automated application of the three traditional sudden-gain criteria; customizable incorporation of adaptations to those criteria; calculation of descriptive statistics; and export of data files for standardized reporting.
