STUDY OBJECTIVES To present an expert consensus, standardized, patient-informed sleep diary. METHODS AND RESULTS Sleep diaries from the original expert panel of 25 attendees of the Pittsburgh Assessment Conference(1) were collected and reviewed. A smaller subset of experts formed a committee and reviewed the compiled diaries. Items deemed essential were included in a Core sleep diary, and tho...

Affective events theory (AET) argues that everyday negative events are likely to lower both daily work engagement and momentary positive affect. These problems can then persist on subsequent days. However, AET also argues that individual strategies can diminish the ill effects of negative events. We explicitly focused on good sportsmanship or abstaining from unnecessary complaints and criticism...

OBJECTIVE To explore the use and interpretation of self reported on/off diary data for assessment of daily motor fluctuations in Parkinson's disease. METHODS 26 consecutive non-demented patients with fluctuating Parkinson's disease received standardised training on how to fill out the four category CAPSIT-PD on/off diary, followed by four hours of clinical observation and four weeks of daytim...

Immersion is commonly described by gamers and gamereviewers as an important aspect of a videogame. In this paper, we investigate the relationship between the immersive experience of videogames and the addictive nature of games. Building on Charlton’s (2002) study of addiction and engagement in computing, we conducted a questionnaire study of people who play videogames. It seems that videogames ...

This paper explores how we, as individuals, purposefully or serendipitously encounter “new music” (that is, music that we haven’t heard before) and relates these behaviours to music information retrieval activities such as music searching and music discovery via use of recommender systems. 41 participants participated in a three-day diary study, in which they recorded all incidents that brought...

BACKGROUND Diaries are the most commonly used adherence measurement method in home-based rehabilitation trials, yet their completion and validity varies widely between trials. We aimed to: (1) generate theory to explain this variation, (2) create an optimised diary and (3) evaluate the optimised diary's validity. METHODS Stage 1. DEVELOPMENT using a multiple case study approach, we collecte...

With the proliferation of digital reading technologies and their underlying ecosystem, practices of reading are currently undergoing significant changes. Despite the currency of the topic, we find there is little empirical research on how people incorporate digital reading technologies into their existing leisure-based reading practices. In this paper, we explore the place of ereading for pleas...

Although play behavior is difficult to define, it has been abundantly documented in the cetacean literature. Play behavior is prevalent among the various taxa and is exhibited by individuals of all age classes. However, it is often difficult to follow individuals, observe underwater behavior, and obtain multiple sightings of individuals when investigating free-ranging populations. Captive studi...

Context: The research about motivation in software engineering has provided important insights into characterizing factors and outcomes related to motivation. However, the complex relationships among these factors, including the moderating and mediating effects of organisational and individual characteristics, still require deeper explanatory investigation. Objective: Our general goal is to bui...

Gamification is commonly employed in designing interactive systems to enhance user engagement and motivations, or to trigger behavior change processes. Although some quantitative studies have been recently conducted aiming at measuring the effects of gamification on users’ behaviors and motivations, there is a shortage of qualitative studies able to capture the subjective experiences of users, ...
