GASS is an acronym that stands for "Goal Attainment Scaling System." The Goal Attainment Scaling System is a method used in psychology and rehabilitation to measure and evaluate the progress and achievement of goals in an individual's treatment or intervention plan. It is a form of outcome measurement that quantifies the level of goal achievement on a scale.
In the GASS system, goals are typically set collaboratively between the individual and the professional assisting them. The goals can be related to various areas of life, such as physical, cognitive, emotional, social, or functional domains. These goals are then translated into a numerical scale, usually ranging from -2 to +2 or -3 to +3, depending on the specific scoring system used.
Each numerical point on the scale represents a specific level of goal attainment. For instance, -2 may indicate a significant decrease or worsening of the targeted behavior or condition, while +2 may signify the complete achievement or resolution of the goal. The scoring is based on pre-determined criteria and is often evaluated through direct observation, interviews, or assessments.
The GASS method offers a structured and standardized approach to objectively measure treatment progress, allowing professionals to assess the effectiveness of interventions and tailor future strategies based on the results. By providing a quantifiable measure of goal achievement, GASS enables clinicians, researchers, and individuals to track and compare progress over time, facilitating evidence-based decision-making and enhancing overall treatment outcomes.
