“…As in other studies, albeit on other pathological conditions, 31 we noted numerically higher scores when the questionnaires were administered by an interviewer, although the difference was only significant for the pain domain of the WIQ. This is commonly explained as being the result of social desirability bias, 32 in which participants may state that they are less affected when interviewed by research staff than when the questionnaires are self-administered.…”

CONTEXT AND OBJECTIVE: Many clinical investigations use generic and/or specific questionnaires to obtain information about participants and patients. There is disagreement about whether the administration method can affect the results. The aim here was to determine whether, among patients with intermittent claudication (IC), there are differences in the Walking Impairment Questionnaire (WIQ) and European Quality of Life-5 Dimension (EQ-5D) scores with regard to: 1) the questionnaire administration method (self-administration versus face-to-face interview); and 2) the type of interviewer (vascular surgeon, VS, versus general practitioner, GP). DESIGN AND SETTING: Cross-sectional observational multicenter epidemiological study carried out within the Spanish National Health Service. METHODS: 1,641 evaluable patients with IC firstly completed the WIQ and EQ-5D questionnaires and then were interviewed by their doctor on the same day. Pearson correlations and Chi-square tests were used. RESULTS: There was a strong correlation (r > 0.800; P < 0.001) between the two methods of administering the WIQ and EQ-5D questionnaires, and between the VS and GP groups. Likewise, there was a high level of concordance (P > 0.05) between the different dimensions of the WIQ-distance and EQ-5D (selfadministration versus face-to-face) in the VS and GP groups. CONCLUSION: There was no difference between the different methods of administering the WIQ and EQ-5D questionnaires, among the patients with IC. Similarly, the two types of interviewers (VS or GP) were equally valid. Therefore, it seems unnecessary to expend effort to administer these questionnaires by interview, in studies on IC. RESULTADOS: Houve forte correlação (r > 0,800; P < 0,001) entre os dois métodos de administração do WIQ e EQ-5D; e entre os grupos CV e MG. Também houve alto nível de concordância (P > 0,05) entre as diferentes dimensões do WIQ-distância e EQ-5D (autoadministrado versus entrevista presencial), nos grupos CV e MG. CONCLUSÃO: Em pacientes com CI, não há diferenças entre as diferentes formas de administrar os questionários WIQ e EQ-5D. Da mesma forma, os dois tipos de entrevistador (CV ou MG) foram igualmente válidos. Portanto, não parece necessário despender esforço para administrar esses questionários através de entrevista, em estudos de CI. RESUMO

“…However, women were more often able to report their waist circumference and waist hip ratio. It has previously been shown that women are more willing to respond to questionnaires overall [59][60][61], and this might also apply to response pattern of individual questions.…”

“…One third of the population in study 1 was randomly selected for telephone interview. This group was not included in this paper in order to ensure comparability between the two studies, since it has been shown that the two study methods may give slightly different results (26). The response rate for the mailed questionnaire group in study 1 was 58%.…”
