Table 1 Feasibility elements

From: Evaluation of an anti-stigma intervention for Mexican psychiatric trainees

Acceptability The way the target population reacts to the intervention. Focuses on establishing whether individuals consider the intervention is appropriate for them or not. Acceptability was established by assessing satisfaction; intent to continue using the intervention; appropriateness and perceived effects.
Demand The actual use of the intervention along with the intention of using the intervention. This was established by reporting which percentage of the total target population attended any of the two sessions. This was also used to establish recruitment and retention rates.
Implementation This element was focused on evaluating if the execution of the intervention was successful, and on establishing the factors affecting the implementation, and the efficiency and quality of the intervention.
Practicality The ability of participants to take part in the activities included in the intervention, which was evaluated with the evaluation questionnaire and the qualitative data.
Adaptation Any modification or alteration made to the intervention to make it more suitable in a new context. However, this element refers to adaptations made to an already existing model that it is being tested in a new setting. Because this is a newly developed intervention, only adaptations made to the original plan were described.
Integration Establishing if the intervention fits, and can be sustained, within the host organisation. This was assessed with the evaluation questionnaire and the qualitative data.
Expansion The potential success of extending an already tested intervention to a different setting. However, because this is an original intervention, for this element, we only reported participants’ perceptions of fitness.
Limited-efficacy testing As its name suggests, this element seeks to measure how effective an intervention is, even in a controlled setting, this was assessed by comparing pre- and post-outcomes questionnaires’ results.
