“…The stability of decreased alcohol consumption and alcohol-related problems for up to 6 months is also consistent with findings from previous studies [18,43,44]. One study has shown increases in scores on such outcome measures after 6 months [19], something that we did not see in this study.…”

“…The finding of a short-term decrease in alcohol consumption and alcohol-related problems, noted at the 3-month follow-up, is consistent with previous research on Web-based interventions for problematic alcohol use [18,25,28,43,44,45]. The stability of decreased alcohol consumption and alcohol-related problems for up to 6 months is also consistent with findings from previous studies [18,43,44].…”

Background/Aims: Most problematic alcohol users never seek professional help to reduce their use, and Web-based interventions might fulfill users' unmet needs for professional support. Methods: This randomized controlled trial compared two open Web-based interventions, one extended self-help program and one brief screening and feedback intervention, with an assessment-only control group. Participants were 633 Internet help seekers with at least hazardous alcohol use (Alcohol Use Disorders Identification Test, AUDIT ≥6 for women and ≥8 for men). Results: All groups reduced their alcohol use at 3-month follow-up (p < 0.001), remaining stable at the 6- and 12-month follow-ups (n.s.) according to AUDIT-C and AUDIT scores (intention-to-treat, ITT, analysis). Per protocol (PP) analysis, including only participants who accessed the interventions and also reported accessing additional outside interventions during the trial, showed that about 75% of extended self-help participants moved from probable dependence, harmful or hazardous use to lower alcohol use levels at 3- and 6- and 12-month follow-ups, compared to about 40-60% of brief intervention users and controls who accessed extra help (p < 0.05). Conclusion: ITT analysis suggested parity over time for all interventions, including assessment only, in reducing problematic alcohol use. In contrast, PP analysis suggested that cognitive-behavioral extended self-help in combination with other interventions was more effective in changing alcohol use than brief intervention or assessment only.

“…Several studies suggest that underreporters are more likely to estimate low intake of foods perceived as unhealthy or undesirable (eg, sweets, fats, and snacks) than those perceived as healthy (eg, fruits, vegetables, and reduced fat products) [30,33,34]. Some of the characteristics of e-EPIDEMIOLOGY, such as asynchrony [35-38] and the ease with which privacy can be maintained [39], have made it possible to collect data anonymously on the Internet. This factor could contribute to reducing the problem of underestimation, mainly with those foods/drinks that are socially considered unhealthy, as this would minimize the effect of the psychological factors previously mentioned.…”

“…Another limitation of this study is the possible rate of nonresponse. Some of the characteristics of these types of mobile technologies, such as asynchrony [35-38], the ease with which privacy can be maintained [39], and the light workload for the participants (1 minute per day), helped to increase participation and could have contributed to the minimization of nonresponse rates. Young people have expressed their preference for methods of dietary intake evaluation that utilize new technologies, as they can easily be incorporated into their lifestyles, and are more amenable than traditional paper-based methods [9,17].…”

BackgroundThere is a great necessity for new methods of evaluation of dietary intake that overcome the limitations of traditional self-reporting methods.ObjectiveThe objective of this study was to develop a new method, based on an app for mobile phones called e-EPIDEMIOLOGY, which was designed to collect individual consumption data for a series of foods/drinks, and to compare this app with a previously validated paper food frequency questionnaire (FFQ).MethodsUniversity students >18 years of age recorded the consumption of certain foods/drinks using e-EPIDEMIOLOGY during 28 consecutive days and then filled out a paper FFQ at the end of the study period. To evaluate the agreement between the categories of habitual consumption for each of the foods/drinks included in the study, cross-classification analysis and a weighted kappa statistic were used.ResultsA total of 119 participants completed the study (71% female, 85/119; 29% male, 34/119). Cross-classification analysis showed that 79.8% of the participants were correctly classified into the same category and just 1.1% were misclassified into opposite categories. The average weighted kappa statistic was good (κ=.64).ConclusionsThe results indicate that e-EPIDEMIOLOGY generated ranks of dietary intakes that were highly comparable with the previously validated paper FFQ. However, it was noted that further testing of e-EPIDEMIOLOGY is required to establish its wider utility.

“…Some of the characteristics of these types of mobile technologies, such as asynchrony (36)(37)(38)(39), the ease with which privacy can be maintained (40), as well as the light workload for the participants (one minute per day), helped to increase participation. In addition, the recording of foods/drinks intake was to be completed during 28 consecutive days using the application and at the end of this period using the short paper FFQ, minimizing the likelihood of changes in dietary intake.…”

Is there any alternative to traditional food frequency questionnaire for evaluating habitual dietary intake?

Palabras clave:Métodos epidemiológicos. Evaluación nutricional. Registros de dieta. Encuestas y cuestionarios. Teléfono inteligente. ResumenIntroducción: los métodos de evaluación de la dieta son importantes instrumentos para la investigación nutricional. Los cuestionarios de frecuencia de consumo de alimentos (CFCA) han sido los métodos utilizados con mayor frecuencia en los estudios epidemiológicos y de intervención. Hay una gran necesidad de nuevas herramientas que superen las limitaciones de estos métodos tradicionales. Objetivos: los objetivos del presente estudio fueron desarrollar un nuevo método, basado en una aplicación para teléfonos móviles llamada e-EPIDEMIOLOGY, diseñada para registrar los datos de consumo individual de una serie corta de alimentos/bebidas, y comparar estos datos con los obtenidos a partir de un CFCA corto (en papel) validado previamente. Métodos: estudiantes universitarios mayores de 18 años registraron el consumo de ciertos alimentos/bebidas usando e-EPIDEMIOLOGY durante 28 días consecutivos y cumplimentaron un CFCA corto (en papel) al fi nal del periodo de estudio. Para evaluar el acuerdo entre ambos métodos se utilizaron el coefi ciente de correlación de Spearman, el análisis de clasifi cación cruzada y el kappa ponderado. Resultados: un total de 119 participantes completaron el estudio (71,4% mujeres y 28,6% hombres). El coefi ciente de correlación de Spearman medio entre ambos métodos fue 0,73. La media del porcentaje de clasifi cación cruzada en la categoría de "acuerdo exacto + adyacente" fue 91,6%. La media del kappa ponderado fue 0,60. Conclusiones: los resultados indican que e-EPIDEMIOLOGY tiene buena concordancia con el CFCA corto (en papel) previamente validado. Sin embargo, son necesarias más pruebas con e-EPIDEMIOLOGY para establecer su utilidad de forma más amplia.
