The inadequate health literacy of elderly people pushes researchers to the use of interviews as a method of administration. The aims of this study were to compare the results obtained with an interviewer\u2010administered and a self\u2010administered medication adherence questionnaire and to evaluate the consequences of the adherence status classification of individuals.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cross\u2010sectional study was performed in which the Medida de Ades\u00e3o aos Tratamentos adherence questionnaire was administered to adult patients who were taking at least 1 antihypertensive drug. The data were collected in 7 community pharmacies in central Portugal between March 2014 and September 2015 in 2 different phases: in the first phase, the questionnaire was applied during a healthcare professional interview, and the second phase involved a self\u2010report administration. A confirmatory factor analysis was conducted, and the measurement and structural invariances across the application methods were examined.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A sample of 425 patients with a mean age of 68.21\u00a0\u00b1\u00a010.56\u00a0years participated in the study. The confirmatory factor analysis revealed that both the interview and self\u2010report had a good fit with the original model, although the self\u2010report results exhibited a better fit. In the interview administration, we obtained lower values for skewness and higher levels of kurtosis. The patients subjected to the interview administration presented with a 9.7% higher tendency to answer \u201cnever\u201d when compared with the self\u2010administered application, which overestimated adherence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The interview administration method induced bias that led to a higher percentage of \u201cnever\u201d answers and a subsequent overestimation of adherence levels. Self\u2010report administration should be preferred in the application of medication adherence questionnaires.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jep.12773","type":"journal-article","created":{"date-parts":[[2017,7,17]],"date-time":"2017-07-17T10:02:40Z","timestamp":1500285760000},"page":"1252-1257","source":"Crossref","is-referenced-by-count":9,"title":["Influence of the mode of administration on the results of medication adherence questionnaires"],"prefix":"10.1111","volume":"23","author":[{"given":"Ana C.","family":"Cabral","sequence":"first","affiliation":[{"name":"Pharmacology and Pharmaceutical Care Laboratory, Faculty of Pharmacy University of Coimbra  Coimbra Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7542-0497","authenticated-orcid":false,"given":"Mariana","family":"Moura\u2010Ramos","sequence":"additional","affiliation":[{"name":"Cognitive and Behavioural Center for Research and Intervention (CINEICC), Faculty of Psychology and Educational Sciences University of Coimbra  Coimbra Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6533-9932","authenticated-orcid":false,"given":"Margarida","family":"Castel\u2010Branco","sequence":"additional","affiliation":[{"name":"Pharmacology and Pharmaceutical Care Laboratory, Institute for Biomedical Imaging and life Sciences, Faculty of Pharmacy University of Coimbra  Coimbra Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1950-9360","authenticated-orcid":false,"given":"Margarida","family":"Caramona","sequence":"additional","affiliation":[{"name":"Pharmacology and Pharmaceutical Care Laboratory, Institute for Biomedical Imaging and life Sciences, Faculty of Pharmacy University of Coimbra  Coimbra Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8529-9595","authenticated-orcid":false,"given":"Fernando","family":"Fernandez\u2010Llimos","sequence":"additional","affiliation":[{"name":"Institute for Medicines Research (iMed.
