Difference in prevalence of common mental disorder as measured using four questionnaire delivery methods among young people in rural Zimbabwe.

BACKGROUND: Previous studies have suggested that interviewer-administered questionnaires can under-estimate the prevalence of depression and suicidal ideation when compared with self-administered ones. We report here on differences in prevalence of reporting mental health between four questionnaire delivery modes (QDM). METHODS: Mental health was assessed using the Shona Symptom Questionnaire (SSQ), a locally validated 14-item indigenous measure for common mental affective disorders. A representative sample of 1495 rural Zimbabwean adolescents (median age 18) was randomly allocated to one of four questionnaire delivery modes: self-administered questionnaire (SAQ), SAQ with audio (AASI), interviewer-administered questionnaire (IAQ), and audio computer-assisted survey instrument (ACASI). RESULTS: Prevalence of common affective disorders varied between QDM (52.3%, 48.6%, 41.5%, and 63.6% for SAQ, AASI, IAQ, and ACASI respectively (P<0.001)). Fewer participants failed to complete SSQ using IAQ and ACASI than other methods (1.6% vs. 12.3%; P<0.001). Qualitative data suggested that respondents found it difficult answering questions honestly in front of an interviewer. LIMITATIONS: Direction of accuracy cannot be ascertained due to lack of objective or clinical assessments of affective disorders. CONCLUSIONS: Estimates of prevalence of psychosomatic symptoms and suicidal ideation varied according to mode of interview. As each mode's direction of accuracy remains unresolved evaluations of interventions continue to be hampered

The effect of emphasis in telephone survey questions on survey measurement quality

Questionnaire design texts commonly recommend emphasizing important words, including capitalization or underlining, to promote their processing by the respondent. In self-administered surveys, respondents can see the emphasis, but in an interviewer-administered survey, emphasis has to be communicated to respondents through audible signals. We report the results of experiments in two US telephone surveys in which telephone survey questions were presented to interviewers either with or without emphasis. We examine whether emphasis changes substantive answers to survey questions, whether interviewers actually engage in verbal emphasis behaviors, and whether emphasis changes the interviewer- respondent interaction. We find surprisingly little effect of the question emphasis on any outcome, with the primary effects on vocal intonation and the interviewer-respondent interaction. Thus, there is no evidence here to suggest that questionnaire designers should use emphasis in interviewer-administered questionnaires to improve data quality. As the first study on this topic, we suggest many opportunities for future research

Questionnaire design decisions when transitioning from an interviewer-administered to a self-administered online mode (Version 1.0)

Large-scale surveys are increasingly moving from (face-to-face or telephone-based) interviewer-administered to self-administered online modes. To ensure high measurement quality and maximum comparability and equivalence between the source questionnaire and its adaptation - across modes as well as across survey waves - various aspects of question design must be considered and several decisions need to be made concerning question presentation and wording. This survey guideline summarizes good practices on how to transition questionnaires from interviewer- to self-administered web surveys and gives recommendations and examples for major adaptation issues as well as general questionnaire design elements relevant to web surveys. In this context, we focus on the switch from an interviewer-based to an online mode (although mixed-mode designs are also conceivable).Groß angelegte Studien werden zunehmend von interviewerbasierten (persönlichen oder telefonischen) Befragungen auf selbstverwaltete Onlineerhebungen umgestellt. Um eine hohe Datenqualität und ein Höchstmaß an Vergleichbarkeit und Äquivalenz zwischen dem Ausgangsfragebogen und seiner Adaptation - sowohl über verschiedenen Modi als auch Erhebungswellen hinwe - zu gewährleisten, müssen verschiedene Aspekte des Fragebogendesigns berücksichtigt und eine Reihe von Entscheidungen in Bezug auf die Präsentation und Formulierung von Fragen getroffen werden. Dieser Erhebungsleitfaden fasst bewährte Methoden zur Umwandlung der Fragebögen von interviewgestützten zu selbstgestützten Onlineerhebungen zusammen und gibt Empfehlungen und Beispiele für wichtige Anpassungsfragen sowie zu allgemeinen Gestaltungselementen von Fragebögen, die für Onlineumfragen relevant sind. In diesem Zusammenhang konzentrieren wir uns auf den Wechsel von einem interviewergestützten zu einem Onlinemodus (obwohl auch gemischte Modi denkbar sind)

Performance of the EQ-5D-Y Interviewer Administered Version in Young Children

(1) Background: An estimated 78% of South African children aged 9&ndash;10 years have not mastered basic reading, therefore potentially excluding them from self-reporting on health-related outcome measures. Thus, the aim of this study was to compare the performance of the EQ-5D-Y-3L self-complete to the newly developed interviewer-administered version in children 8&ndash;10 years. (2) Methods: Children (n = 207) with chronic respiratory illnesses, functional disabilities, orthopaedic conditions and from the general population completed the EQ-5D-Y-3L self-complete and interviewer-administered versions, Moods and Feelings Questionnaire (MFQ) and Faces Pain Scale-Revised (FPS-R). A functional independence measure (WeeFIM) was completed by the researcher. (3) Results: The 8-year-olds had significantly higher missing responses (x2 = 14.23, p &lt; 0.001) on the self-complete version. Known-group and concurrent validity were comparable across dimensions, utility and VAS scores for the two versions. The dimensions showed low to moderate convergent validity with similar items on the MFQ, FPS-R and WeeFIM with significantly higher correlations between the interviewer-administered dimensions of Mobility and WeeFIM mobility total (z = 1.91, p = 0.028) and Looking After Myself and WeeFIM self-care total (z = 3.24, p = 0.001). Children preferred the interviewer-administered version (60%) (x2 = 21.87, p &lt; 0.001) with 22% of the reasons attributed to literacy level. (4) Conclusions: The EQ-5D-Y-3L interviewer-administered version is valid and reliable in children aged 8&ndash;10 years. The results were comparable to the self-complete version indicating that versions can be used interchangeably

Item nonresponse to financial questions in household surveys: An experimental study of interviewer and mode effects

We analyze nonresponse to questions on financial items such as income and asset holdings in the SAVE survey, exploiting a controlled field experiment. As part of the SAVE study, a representative survey conducted in Germany in 2001, questions on household income and financial assets were administered using different interview modes (personal interview vs. drop-off questionnaire). The data also allow investigating the influence of interviewer characteristics on nonresponse. Our results are in line with predictions derived from models of survey response behavior that have been developed in survey research and social psychology.

Dietary assessment methods for micronutrient intake in elderly people: a systematic review

The European micronutrient recommendations aligned (EURRECA) Network of Excellence seeks to establish clear guidelines for assessing the validity of reported micronutrient intakes among vulnerable population groups. A systematic literature review identified studies validating the methodology used in elderly people for measuring usual dietary micronutrient intake. The quality of each validation study selected was assessed using a EURRECA-developed scoring system. The validation studies were categorised according to whether the reference method applied reflected short-term intake ( <7 d), long-term intake ( = 7 d) or used biomarkers (BM). A correlation coefficient for each micronutrient was calculated from the mean of the correlation coefficients from each study weighted by the quality of the study. Thirty-three papers were selected, which included the validation of twenty-five different FFQ, six diet histories (DH), one 24-h recall (24HR) and a videotaped dietary assessment method. A total of five publications analysed BM, which were used to validate four FFQ, and one 24HR, presenting very good correlations only for vitamin E. The analysis of weighted correlation coefficients classified by FFQ or DH showed that most of the micronutrients had higher correlations when the DH was used as the dietary method. Comparing only FFQ results showed very good correlations for measuring short-term intakes of riboflavin and thiamin and long-term intakes of P and Mg. When frequency methods are used for assessing micronutrient intake, the inclusion of dietary supplements improves their reliability for most micronutrients

Comparison of the self-administered and interviewer-administered modes of the child-OIDP

Background: The mode of questionnaire administration may affect the estimates and applicability of oral health-related quality of life indicators. The aim of this study was to compare psychometrically the self-administered Child-OIDP index with the original interviewer-administered instrument.Methods: This was a cross-sectional study of 144 consecutive children aged 9-16 years referred to orthodontic clinics in Bedfordshire. To compare the two administration modes of the Child-OIDP, the sample was randomly split in two groups. The two groups were analysed in terms of baseline characteristics, self-perceived measures (self-rated oral health, self-perceived need for braces, happiness with dental appearance, frequency of thinking about dental appearance), Child-OIDP performance scores and overall score and psychometric properties (criterion validity and internal reliability).Results: No significant difference between the two groups was found in relation to their sociodemographic profile and self-perceived measures. The self-and interviewer-administered Child-OIDP had identical mean scores and did not differ in recording any of the eight performances (p >= 0.206). For criterion validity, the correlation coefficients of the Child-OIDP with self-perceived measures were not different between the two modes of administration (p >= 0.118). Furthermore, the Cronbach's alpha values of the two groups were similar (p = 0.466).Conclusion: This study demonstrated that the self-administered Child-OIDP performed the same as the original interviewer-administered mode, while at the same time reducing administration burden. This provides support for the use of the self-administered Child-OIDP. Further studies should focus on a more comprehensive psychometric evaluation
