Table 2 The APEASE criteria for designing and evaluating interventions

From: Development of a context-sensitive physical activity intervention for persons living with HIV and AIDS of low socioeconomic status using the behaviour change wheel

Criterion Description
Affordability The ability of the intervention to meet the expense of the intervention. An intervention is affordable if the budget of the intervention allows it to be delivered to, or accessed by, all those for whom it is intended.
Practicability The viability of the intervention. A practicable intervention is one that can be delivered as designed through the means intended to the target population.
Effectiveness and cost-effectiveness The effect size of the intervention in relation to the desired objectives in a real world context. Cost-effectiveness refers to the ratio of effect to cost.
Acceptability The extent to which relevant stakeholders (public, professional and political) judge an intervention appropriate.
Side-effects/Safety An intervention may be effective and practicable but have unwanted or unintended consequences. This needs to be taken into consideration when planning the intervention.
Equity The extent to which an intervention may reduce or increase the disparities in standard of living, wellbeing or health between different sectors of society.
