The three test models display associations between the quality domains of a programme. In model A a more developed planning and delivery system is accompanied by a higher score on measures and interventions applied (relation a), resulting in higher perceived scores assigned to essential psychosocial principles (relation b) and general evaluation criteria (relation c). Model B follows the same line of reasoning but now the planning and delivery system status directly influences perceived essential psychosocial principles (relation d) and general evaluation criteria scores as well (relation e). Model C is restricted to the influence of a change in planning and delivery score on the other domains.
