The QGPS procedure is based on four widely-accepted dimensions of quality in health promotion and prevention: concept, structure, process and results. They represent the framework, which has been operationalized by eight quality areas and 32 quality features on the basis of a comprehensive literature review (see also the QHPS quality model | QHPS quality chain). Each feature appears as a statement, e.g., “Has the target group been defined against the backdrop of needs?”
The programme’s compliance with the defined quality requirements can be scored on three levels: yes (2 points), partially (1 point), no (0 points). Detailed descriptions of each feature and highly standardized descriptors (i.e. quality indicators) allow for an objective assessment (see the QHPS manual; currently available in German only. An English language version is planned).
The number of accumulated points is considered in relation to the total possible points, and ultimately converted to percentages. Calculations can be done for each quality dimension, as well as across all dimensions.

It is likely that programmes will not always be able to fulfill all quality requirements. It strongly depends on how fully they have been developed and implemented. Five quality levels have been defined which allow for a differentiated interpretation of these stages.

The ascertained total score of 53.5% means that the rated programme is at the ‘Average level’.
