Additional information about the intervention material is provided elsewhere.
However, further testing of intervention material and evaluation methods is needed.
DC, SM, and CNM contributed to study design, intervention material development, and survey questionnaire design.
Using written information, study personnel demonstrated the correct use of the intervention material (full implementation of the intervention).
The intervention material was initially developed from the researchers' experience in the drug and alcohol and mental health fields.
The intervention material was aseptic, purified, cryopreserved PfSPZ (PfSPZ Challenge) isolated from salivary glands of aseptically reared mosquitoes.
Intervention material was given to the study sites in closed boxes marked only with the randomisation number.
In addition, a variety of patients, in terms of their gender, age, and educational background, showed an interest in the intervention material.
First, the students read the intervention material themselves, then they carried out the assignments, and practised giving feedback to each other by e-mail.
It is suggested that it is possible and most likely useful to a varied group of patients to work with the intervention material that we provided.
