"Nearly 23% of all telephone interviews in the most recently completed wave of the Panel Study of Income Dynamics break off at least once, requiring multiple sessions to complete the interview. Given this high rate, a study was undertaken to better understand the causes and consequences of temporary breakoffs in a computer-assisted telephone interview setting. The majority of studies examining breakoffs have been conducted in the context of self-administered web surveys. The present study uses new paradata collected on telephone interview breakoffs to describe their prevalence, associated field effort, the instrument sections and questions on which they occur, their source - whether respondent-initiated, interviewer-initiated, or related to telephone problems - and associations with respondent and interviewer characteristics. The results provide information about the survey response process and suggest a set of recommendations for instrument design and interviewer training, as well as additional paradata that should be collected to provide more insight into the breakoff phenomenon."

Objetivo: Estudiar la correlación de la Telephone Interview for Cognitive Status modificada en español(STICS-m) con el Mini-Mental State Examination (MMSE) y predecir la capacidad de la primera para detectar el desarrollo de demencia. Método: Ciento seis sujetos de un estudio de intervención dietética fueron evaluados personalmente con el MMSE y por teléfono con la STICS-m. La correlación entre ambos se midió con el coeficiente de correlación intraclase (CCI) de consistencia. Además, 932 participantes mayores de 55 años de la cohorte 'Seguimiento Universidad de Navarra' fueron evaluados con la STICS-m. Durante una mediana de seguimiento de 6,5 años, se recogió información sobre el desarrollo de demencia. Mediante regresión logística se estudió la asociación entre la puntuación de la STICS-m o el cambio a 2 años en la puntuación y el riesgo de desarrollar demencia, ajustando por apolipoproteína E, edad y años de educación universitaria. Resultados: El CCI entre el MMSE y la STICS-m fue de 0,31 (intervalo de confianza del 95% [IC95%]:0,13-0,48). La odds ratio (OR) ajustada para el desarrollo de demencia para cada punto adicional en la puntuación basal de la STICS-m fue de 0,85 (IC95%: 0,72-1,02; p = 0,084). Al considerar el cambio en la puntuación a los 2 años como variable independiente, la OR fue de 0,79 (IC95%: 0,67-0,93; p = 0,006). ; Objective: To compare the Spanish version of the modified Telephone Interview of Cognitive Status(STICS-m) with the Mini-Mental State Examination (MMSE) and predict its ability to detect the development of dementia. Method: 106 participants in a dietary intervention trial underwent face-to-face evaluation with the MMSE, and phone interview with the STICS-m. The correlation between STICS-m and MMSE was assessed with the intraclass correlation coefficient (ICC) of consistency. Secondly, 932 participants over 55 years old from the 'Seguimiento Universidad de Navarra' cohort were evaluated with the STICS-m and data ondementia diagnosis were gathered (median follow-up time of 6.5 years). A logistic regression model evaluated the association between STICS-m score or 2-year changes in STICS-m score and risk of developing dementia, adjusting for ApoE, age and years of university education. Results: The ICC between the MMSE and the STICS-m was 0.31 (95% confidence interval [95%CI]: 0.13-0.48). The adjusted odds ratio (OR) for the development of dementia for each additional point in the baseline STICS-m score was 0.85 (95%CI: 0.72-1.02; p = 0.084). When considering the 2-year change inthe STICS-m score as exposure, the OR for the development of dementia was 0.79 (95%CI: 0.67-0.93; p = 0.006). Conclusions: The weak correlation between the STICS-m and the MMSE reflects moderate-low concurrent validity. Even so, the STICS-m can be regarded as an useful tool in the epidemiological setting since increasing scores appear to be able to predict a lower risk of developing dementia. ; The SUN Project has received funding from the Spanish Government-Instituto de Salud Carlos III, and the European Regional Development Fund (FEDER) (RD 06/0045, CIBER-OBN, Grants PI10/02658, PI10/02293, PI13/00615,PI14/01668, PI14/01798, PI14/01764, and G03/140), the Navarra Regional Government (45/2011, 122/2014), and the University of Navarra.
