User experience (UX) research relies heavily on survey scales to measure users' subjective experiences with technology. However, repeatedly raised concerns regarding the improper use of in UX and adjacent fields call for a systematic review current measurement practices. Therefore, we conducted literature review, screening 153 papers from four years ACM Conference Human Factors Computing Systems proceedings (ACM CHI 2019 2022), which 60 were eligible empirical studies using study...

Past research has demonstrated that aesthetics affect users' experiences in various ways. However, there is little on the impact of interface user performance a smartphone app context. The present paper addresses this gap using an online experiment ( N = 281). Two variants same web were created and manipulated their aesthetics. Participants randomly assigned to either variant asked explore before answering questions concerning app's content. Results showed significant positive effect...

Transparency is widely regarded as crucial for the responsible real-world deployment of artificial intelligence (AI) and considered an essential prerequisite to establishing trust in AI. There are several approaches enabling transparency, with one promising attempt being human-centered explanations. However, there little research into effectiveness explanations on end-users' trust. What complicates comparison existing empirical work that measured different ways. Some researchers measure...

Measuring theoretical concepts, so-called constructs, is a central challenge of Player Experience research. Building on recent work in HCI and psychology, we conducted systematic literature review to study the transparency measurement reporting. We accessed ACM Digital Library analyze all 48 full papers published at CHI PLAY 2020, those, 24 used self-report measurements were included review. assessed specifically, whether researchers reported What, How Why they measured. found that matched...

Trust is often cited as an essential criterion for the effective use and real-world deployment of AI. Researchers argue that AI should be more transparent to increase trust, making transparency one main goals XAI. Nevertheless, empirical research on this topic inconclusive regarding effect trust. An explanation ambiguity could trust operationalized differently within In position paper, we advocate a clear distinction between behavioral (objective) measures reliance attitudinal (subjective)...

Trust is crucial for human interaction with artificial intelligence (AI) and frequently measured through questionnaires or rating scales. One commonly used questionnaire in AI research the between People Automation scale (TPA). However, its psychometric quality has yet to be examined context of AI. More recently, a Scale Explainable (TXAI) was recommended but not empirically evaluated. In this study, we assessed qualities both scales, using confirmatory exploratory factor analyses test...

Despite its importance, few validated scales exist to measure aesthetics in HCI. One notable exception, the Visual Aesthetics of Websites Inventory (VisAWI), has never been English. Furthermore, VisAWI contains negatively formulated items, which adversely impact psychometric quality survey scales. Consequently, this paper's aim was development a positive-item version VisAWI, VisAWI-pos, as viable alternative original scale. Positive alternatives for negative items scale were developed and...

Carelessness or insufficient effort responding is a widespread problem in online research, with estimates ranging from 3% to almost 50% of participants surveys being inattentive. While detecting carelessness has been subject multiple studies, the factors that reduce prevent are not as well understood. Initial evidence suggests warning statements prior study participation may carelessness, but there lack conclusive high-powered studies. This preregistered randomized controlled experiment...

Code status discussions are useful for understanding patients’ preferences in the case of a cardiac/pulmonary arrest. These can also provide patients with basis informed decision-making regarding life-sustaining treatment. We conducted survey to understand current practices and perceptions code tertiary-care Swiss hospital.

Studies have suggested that taurine may neuro- and cardio-protective functions, but there is little research looking at levels in patients after out-of-hospital cardiac arrest (OHCA). Our aim was to evaluate the association of with mortality neurological deficits a well-defined cohort OHCA patients. We prospectively measured serum concentration upon admission intensive care unit (ICU) University Hospital Basel (Switzerland). analyzed in-hospital (primary endpoint). further evaluated outcomes...

Abstract Objectives Prior research found the gut microbiota-dependent and pro-atherogenic molecule trimethylamine-N-oxide (TMAO) to be associated with cardiovascular events as well all-cause mortality in different patient populations disease. Our aim was investigate prognostic value of TMAO regarding clinical outcomes patients after out-of-hospital cardiac arrest (OHCA). Methods We included consecutive OHCA upon intensive care unit admission into this prospective observational study between...

Measuring the subjective experience of digital game players is essential to player research. Recently, Player Experience Inventory (PXI) was developed, which assesses both functional and psychosocial consequences gameplay. We present a pre-registered independent online study with large sample provide additional evidence psychometric quality for PXI. Responses from 1518 participants were collected, rating recent or memorable playing using PXI related measures. While our results standard...

There is interest in novel blood markers to improve risk stratification patients presenting with cardiac arrest. We assessed associations of different plasma sphingomyelin concentrations and neurological outcome In this prospective observational study, adult arrest were included upon admission the intensive care unit (ICU). studied levels 15 species at hospital discharge (primary endpoint) defined by modified Rankin Scale calculation univariable multivariable logistic regression models...

In this work, we explore the factorial structure of Ubisoft Perceived Experience Questionnaire (UPEQ) and its correlation with game enjoyment. For purpose, an online survey was conducted on experience video League Legends. Three hundred sixty-nine participants provided information about their in- out-of-game demographics rated using UPEQ subscale Interest/Enjoyment from Intrinsic Motivation Inventory. Using confirmatory exploratory factor analysis, found weaknesses in 3-factor model propose...

Motives are essential concepts in understanding a player's experience video games. We report and describe the analysis of widely used questionnaire to measure players' motives games, for Online Gaming Questionnaire (MOGQ). The present research aimed investigate psychometric quality MOGQ context League Legends (LoL). is 27-item self-report scale designed playing online To this end, 256 participants completed an survey asking about their experiences play LoL. Results confirmatory exploratory...

Despite the importance of trust in human-AI interactions, researchers must adopt questionnaires from other disciplines that lack validation AI context. Motivated by need for reliable and valid measures, we investigated psychometric quality two questionnaires, Trust between People Automation scale (TPA) Jian et al. (2000) Scale Context (TAI) Hoffman (2023). In a pre-registered online experiment (N = 1485), participants observed interactions with trustworthy untrustworthy (autonomous vehicle...

Despite its popularity, knowledge of the psychometric quality System Usability Scale (SUS) in German is limited. This paper addresses this by developing a positively worded SUS version and investigating two existing versions. In preregistered first study, initial positive alternatives for negative items were evaluated, versions compared. Based on these results, second study validated new positive-only independently original Results indicated that SUS-DE-Pos, based Rummel (2016), performed...

Since the turn of millennium User Experience (UX) has emerged in field human computer interaction as an extension to classical concept usability. This new approach tries grasp user’s experience whole also considering factors beyond usefulness a product, such pleasure derived from with it. Given fairly young age field, scientific tools for accurate measurements are still rare and lot questions brought up when it comes quality current used UX (Bargas-Avila & Hornbaek, 2011). The goal...
