The authors examined the relationship between psychological strain, emotional dissonance and emotional job demands during a working day of 65 Dutch (military) police officers, using a 5-day diary design. We hypothesized that emotional dissonance partly mediated the relationship between psychological strain at the start and at the end of a work shift. We also tested the mediating role of emotion...

Cast as a manifesto, this chapter presents a set of foundational principles for conducting “video research” within the learning sciences. Our proposed approach draws chiefly upon the literature and methodology of Conversation Analysis (CA). Conversation Analysis developed out of and shares the thematic interests of the broader field of inquiry known as Ethnomethodology (EM). EM is centrally con...

Since gameplay is only realized when the player and game interact, studying player experiences is complicated. Most research designs often emphasise either the structure of the game or the player in isolation of the game itself. In this study an attempt was made to test three different qualitative methods to study playing styles and by extension player experiences, while trying to take into acc...

E. Diener, R. J. Larsen, S. Levine, and R. A. Emmons (1985) distinguished between intensity and frequency as separable components in repeatedly measured affect. In this article, an improved way of differentiating intensity and frequency of affect is proposed that permits one to measure affect intensity separately for each emotion of interest. The results of 3 studies using this method provide f...

Self-presentation is a fundamental aspect of social life, with myriad critical outcomes dependent on others’ impressions. We identify and offer the first empirical investigation of a prevalent, yet understudied, selfpresentation strategy: humblebragging. Across 9 studies, including a week-long diary study and a field experiment, we identify humblebragging—bragging masked by a complaint or humil...

A quantitative food-frequency questionnaire (FFQ) was developed to determine antioxidant intake in athletes. The questionnaire will be valuable for researchers wishing to standardize antioxidant intake or simply document habitual intake during an intervention trial. One hundred thirteen athletes participated in the validity study, of whom 96 completed the questionnaire and blood test, 81 comple...

BACKGROUND Under-reporting of alcohol consumption is widespread; surveys typically capture 40-60% of alcohol sales. However the population distribution of under-reporting is not well understood. METHODS Mixed-methods study to identify factors associated with under-reporting, using the nationally-representative Health Survey for England (HSE) 2011 (overall response rate 66%). Comparison of ret...

In this paper we present Mobilizar, a web-based mobile tool that facilitates the implementation and data collection of self-reported user behavior. Mobilizar was designed with both the researcher and the participant in mind. It provides investigators with a way to setup a new diary study in a matter of minutes and to electronically collect diary data from participants by using internet-enabled ...

BACKGROUND This report describes the performance of a wireless electronic diary (e-diary) system for data collection and enhanced patient-investigator interactions during intensive insulin management in diabetes clinical trials. MATERIALS AND METHODS We implemented a customized electronic communication system featuring an e-diary and a Web portal in three global, randomized, controlled Phase ...
