Survey and behavioral measurements of interpersonal trust

Although many studies treat trust as a situational construct, individual differences can be used to study and predict trusting behavior. We report two studies, the first showing the psychometric properties of a new trust inventory (the Propensity to Trust Survey or PTS), the second study validating this inventory using the standard economic task, the Investment Game. The first study utilized online survey data (N > 8000) to show that the PTS scales were reliable and measured broad constructs related to Big Five personality domains. Trust was related to extraversion and negative neuroticism, and trustworthiness was related to agreeableness and conscientiousness. The second study (N = 90) validated the PTS trust scale as a predictor of behavior in the Investment Game. These findings are evidence that trust and trustworthiness are compound personality traits, and that PTS scales are preferable to general Big Five measures for predicting trusting behavior.     

Trusting Relationships and the Ethics of Interpersonal Action

Abstract

Trust has generally been understood as an intentional mental phenomenon that one party (the truster) has towards another party (the trusted) with respect to some object of value for the truster. In the landmark work of Annette Baier, this trust is described as a three-place predicate: A entrusts B with the care of C, such that B has discretionary powers in caring for C. In this paper we propose that, within the context of thick interpersonal relationships, trust manifests in a different way: as a property of the relationship itself. We argue that this conceptualization has important implications for the debate over the ethics of interpersonal interventions. In particular, when trust is understood in this way, actions that would otherwise be deemed morally troubling may be permissible, or even morally desirable, on account of their role in strengthening trusting relationships.     

In money we trust? The use of financial compensations to repair trust in the aftermath of distributive harm

Trust is vital yet vulnerable in economic exchange relations. In these relations, a widely used strategy in response to distributive harm consists of having the transgressor pay a financial compensation to the victim. This research examines whether financial compensations can increase trust towards a transgressor, and whether the size of the compensation is relevant to this process. We hypothesized and found that whether larger compensations will elicit more trust, depends on how clear the perpetrator’s intention to transgress was. Experiment 1 revealed that trust perceptions increased more by a slight overcompensation of the inflicted harm as compared to an exact or a partial compensation, but not if the transgressor’s bad intentions became clear through the use of deception in the violation. In Experiments 2 and 3, we replicated these findings and further showed that it is not the use of deception per se, but rather the attribution of bad intent that moderates the effect of compensation size. Experiment 4, using a trust game paradigm revealed that this effect not only occurs for small overcompensations, but also for larger overcompensations.     

I’m curious,I’m open to it,I test it,I trust it! A focus groups study to understand a-priori trust in automated buses

Trust is regarded as one of the main predictors for adopting automated buses (ABs). However, theories about trust (development) in technology generally vary and an in-depths study about trust in ABs specifically is still outstanding. The present study fills this gap by presenting results from focus group interviews to trust (development) in shared automated buses prior to exposure. The objectives of this study are to contrast participants’ naïve concepts of trust with theory and to identify underlying factors influencing a-priori trust in ABs. Results show that the N = 21 focus group participants use different strategies to familiarise themselves with the new technology of ABs, e.g., comparisons with familiar technologies, fundamental tendencies to approach or avoid, additional information seeking, or anthropomorphisation. These strategies largely support existing theories on trust (development) in technology. Differences between naïve interpretations of trust and its theoretical assumptions were found in focus group debates where more control over technology limited uncertainty and led to more trust. While theories suggest control and trust to be incompatible opposites, participants see control as a way to enhance trust. We provide starting points for further theory development and expansion and stress the importance of explanations in emerging technologies for trust and acceptance building.     

The Assessment of Trust Orientation

The development of the Trust Inventory, a 40-item measure of trust in generalized others (Generalized Trust) and romantic partners (Partner Trust) is described. A third conceptualization of trust in friends and family members (Network Trust) is also discussed College students (N = 1,229) participated in five stages of test construction and validation. Results indicated that the Trust Inventory scales are reliable, both internally and temporally, and that the Partner Trust and Generalized Trust Scales demonstrate both concurrent and construct validity. The resulting inventory is unique in its capacity to assess these types of trust simultaneously. Evidence supporting the discriminant validity of the Network Trust was mixed, whereas factor analytic treatments of Trust Inventory items supported the distinctiveness of Network Trust as compared to Partner and Generalized Trust, the Network Trust Scale correlated to roughly the same degree as the other two scales with several variables of differential theoretical relevance. Thus, little evidence supporting the incremental validity of Network Trust was observed Discussion focuses on the evidence suggesting the validity of interpretations of Generalized and Partner Trust and considers the issue of additional research regarding Network Trust.

The effect of the dominance of an in-vehicle agent’s voice on driver situation awareness,emotion regulation,and trust: A simulated lab study of manual and automated driving

As in-vehicle voice agents increase in popularity, related research is extending to how voice messages can affect the driver’s cognitive and emotional states. Accordingly, we investigated how in-vehicle agent (IVA) voice dominance and driving automation can affect the driver’s situation awareness (SA), emotion regulation (ER), and trust. To this end, a lab-based experiment was conducted with a medium-fidelity driving simulator using actor-recorded voice agents. Twenty-two female and nineteen male driver-licensed participants were recruited to drive simulated vehicles with voice agents and evaluated. The results demonstrated that compared with the dominant voice, the agent with a submissive voice significantly increased ER in both manual and automated driving. Furthermore, the submissive voice significantly increased trust in automated driving compared with the dominant agent. Cross and synergistic interaction effects exist between voice dominance and driving automation in SA and ER, respectively. This study revealed that both the content of the messages of the IVAs and their voice characteristics are essential for modulating the driver’s SA, ER, and trust in driving. It is expected that larger-scale future studies with simulation or on a real road would increase the validity of this study.     

Measuring trust in teams: Development and validation of a multifaceted measure of formative and reflective indicators of team trust

This article describes the development and validation of a multidimensional instrument designed to measure trust within teams. Trust is conceptualized as a latent variable resulting from distinct but related (formative) indicators, i.e., propensity to trust and perceived trustworthiness, which lead to (reflective) indicators, i.e., behaviours cooperation and monitoring between team members. The instrument was tested in two different samples. The first sample included 98 hospital professionals (14 teams) and provided data for the exploratory factor analysis of this instrument (Study 1). The second sample included responses from 112 teams (395 individuals) from three social-care institutions and was used to apply confirmatory factor analysis (Study 2). Data attesting to the underlying factor structure, internal homogeneity, construct validity, and consensual power of agreement within teams and discriminant power across teams of the instrument are presented. The final 21-item, four-factor version of this measure demonstrates good psychometric properties, with acceptable levels of reliability and validity. We conclude that the scales form a parsimonious, valid, and efficient instrument to assess trust in teams. Potential applications of this measure in research and practice are described and the implications of these findings for future research are discussed.     

A conceptual framework for establishing trust in real world intelligent systems

Intelligent information systems that contain emergent elements often encounter trust problems because results do not get sufficiently explained and the procedure itself can not be fully retraced. This is caused by a control flow depending either on stochastic elements or on the structure and relevance of the input data. Trust in such algorithms can be established by letting users interact with the system so that they can explore results and find patterns that can be compared with their expected solution. Reflecting features and patterns of human understanding of a domain against algorithmic results can create awareness of such patterns and may increase the trust that a user has in the solution. If expectations are not met, close inspection can be used to decide whether a solution conforms to the expectations or whether it goes beyond the expected. By either accepting or rejecting a solution, the user’s set of expectations evolves and a learning process for the users is established. In this paper we present a conceptual framework that reflects and supports this process. The framework is the result of an analysis of two exemplary case studies from two different disciplines with information systems that assist experts in their complex tasks.     

La clarté du concept de soi : validation d’une échelle de mesure en langue française

IntroductionThe self-concept clarity scale (SCC, Campbell et al., 1996) measures the extent to which self-beliefs are perceived as clearly defined, internally consistent and temporally stable.ObjectiveThe study aimed at testing the reliability and validity of a French version of the SCC scale and its relevance to predict the relationship between self-concept and vocational preference.MethodThree studies have been conducted on a total sample of 1114 participants (691 women) aged 15 and 62.ResultsResults revealed that the French version of the SCC had a unidimensional factor structure and high levels of internal consistency and temporal stability (study 1). As predicted, high SCC scores were independently associated with high self-esteem, high conscientiousness, high agreeability, low neuroticism and low social comparison orientation (study 2). Finally, a criterion validity argument was provided by demonstrating that high SCC scores predicted high matching degree between self-concept and occupational preference prototype (study 3).ConclusionThe psychometric properties of the French version of SCC are satisfactory and comparable to those of the English original scale. The use of the SCC scale in academic guidance and career counseling is therefore discussed.     

How the initial level of trust in automated driving impacts drivers’ behaviour and early trust construction

Trust in Automation is known to influence human-automation interaction and user behaviour. In the Automated Driving (AD) context, studies showed the impact of drivers’ Trust in Automated Driving (TiAD), and linked it with, e.g., difference in environment monitoring or driver’s behaviour. This study investigated the influence of driver’s initial level of TiAD on driver’s behaviour and early trust construction during Highly Automated Driving (HAD). Forty drivers participated in a driving simulator study. Based on a trust questionnaire, participants were divided in two groups according to their initial level of TiAD: high (Trustful) vs. low (Distrustful). Declared level of trust, gaze behaviour and Non-Driving-Related Activities (NDRA) engagement were compared between the two groups over time. Results showed that Trustful drivers engaged more in NDRA and spent less time monitoring the road compared to Distrustful drivers. However, an increase in trust was observed in both groups. These results suggest that initial level of TiAD impact drivers’ behaviour and further trust evolution.

Measuring explicit attitude toward doping: Review of the psychometric properties of the Performance Enhancement Attitude Scale

ObjectivesDoping use is seldom an accident – it is a deliberate action often requiring considerable commitment. Attitudes are known to influence this type of action and hence they are likely to be predictive of doping-related behaviours. To measure ‘doping attitude’, a valid and reliable tool is required.DesignThis paper briefly reviews methodological issues in doping attitude research, introduces the Performance Enhancement Attitude Scale (PEAS) and provides a comparative analysis of its reliability and validity as a self-reported measure of a generalized doping attitude.MethodsThe scale's reliability was examined with Cronbach's internal consistency coefficient and test–retest correlations using data from 9 independent studies encompassing 7 years. Confirmatory factor analysis was performed to assess the scale's structure. Known-groups' validation strategy was employed to examine construct validity in 4 studies.ResultsEstimates of the PEAS' internal consistency (ranged between .71 and .91 across various samples) provided good evidence of the scale's simultaneous reliability. The chi-square/df ratio in all cases was below the threshold with an average of 1.85 (ranging from 1.370 to 2.291), indicating an acceptable measurement model fit. Theoretically expected difference in doping attitudes was found between doping users and non-users with elevated PEAS scores from users, as well as predictable dynamics of PEAS scores across the repeated measures, provided support for construct validity of the scale.ConclusionThe psychometric properties of the 17-item unidimensional PEAS suggest that the scale is a useful tool for measuring self-declared attitudes toward doping, with adequate reliability and promising validity estimates. Suggestions are discussed for the continuous scale development and validation process.     

Can we adapt to highly automated vehicles as passengers? The mediating effect of trust and situational awareness on role adaption moderated by automated driving style

The emergence of highly automated driving technology provides safe and convenient travel while also causing user inadaptation. Therefore, based on human factors engineering, it is necessary to study highly automated vehicles (HAVs) that meet different user needs. Thus, this study aims to investigate the relationships between state anxiety, situational awareness, trust, and role adaptation. The adaptation model is constructed to conduct a study on the adaptation of HAVs with different automated styles when user roles change from driver to passenger. Simulated riding was conducted in the HAV experiment (N = 117), collecting scale data after each participant had experienced each automated driving style. A structural equation modeling approach was applied to analyze the adaptation model based on scale data. The results showed that there was a significant correlation between state anxiety, situational awareness, trust, and role adaptation. State anxiety has a significant negative predictive effect on trust, situational awareness, and role adaptation. In addition to its direct impact on role adaptation, state anxiety also has an indirect effect on role adaptation through situational awareness and trust. Furthermore, the automated driving style has been confirmed to have a moderating role in the relationship between the direct and indirect effects of state anxiety and role adaptation. Our findings contribute to multiple streams of the literature and have important implications for designing personalized automated driving to improve user acceptance.     

Trust,Connectivity, and Thriving: Implications for Innovative Behaviors at Work

This study examines how trust, connectivity and thriving drive employees' innovative behaviors in the workplace. Using a sample of one hundred and seventy two employees across a variety of jobs and industries, we investigated the relationship between trust, connectivity (both measured at Time 1), thriving and innovative work behaviors (both measured at Time 2). Trust and connectivity were hypothesized to create a nurturing environment that enables people to thrive and be innovative in their work. The results of structural equation modeling (SEM) indicate a sequential mediation model in which connectivity mediates the relationship between trust and thriving, and thriving mediates the relationship between connectivity and innovative behaviors. The theoretical and practical implications for employee thriving and innovative behaviors at work are discussed.     

Scale validity evaluation with congeneric measures in hierarchical designs

A procedure for validity estimation of multi-component measuring instruments in hierarchical designs is outlined. The method is developed within the framework of the popular latent variable modelling methodology. The approach is readily applicable for examining interrelationship indices between composite sum scores and criterion variables in two-level studies. The procedure is also useful for obtaining estimates and confidence intervals of criterion validity coefficients during the process of scale construction and development with hierarchical data. The method is illustrated with an empirical example.     

组织中管理者信任的前因机制——基于契约与LMX的实证分析

管理者信任是组织运作效率的重要影响因素。为了系统分析契约与领导成员交换(LMX)在组织内部对管理者信任的权变影响模式,本研究采用问卷调查的方法,对契约与LMX如何影响管理者信任的形成进行了研究。154名被试参加了调查,结果表明,契约与LMX的交互作用项对管理者信任的作用显著。进一步分析交互作用方向,结果表明:领导成员交换(LMX)在管理者信任形成中起到主导作用;而在双方LMX一般时,完备的契约可显著降低信任风险,促进管理者信任的形成。据此,我们建议管理者采用相应的权变策略建设组织内管理者信任。
