The assessment of trust orientation

Oxytocin moderates the association between testosterone-cortisol ratio and trustworthiness: A randomized placebo-controlled study

Oxytocin has been proposed to enhance feelings of trust, however, these findings have been difficult to replicate. Environmental or hormonal factors might influence this association. We studied whether oxytocin moderates the association between the testosterone-cortisol ratio, which is associated with risk taking behavior and aggression, and trustworthiness, while controlling for the general level of trust. A randomized double-blind placebo-controlled study with 53 healthy males was performed in which 32IU oxytocin (n = 27) or placebo (n = 26) was administered intranasally. Participants subsequently played the Trust Game in which they were allocated to the role of trustee. In the third phase of the Trust Game, we found a positive association between the testosterone-cortisol-ratio and the proportion of the amount that is returned to the investor (P=<0.01). However, administration of oxytocin reduced reciprocity in those with a high testosterone-cortisol ratio after reciprocity restoration (a significant interaction effect between administration of oxytocin and the testosterone-cortisol ratio in the third phase of the Trust Game, P = 0.015). The third phase of the Trust Game represents the restoration of reciprocity and trustworthiness, after this is violated in the second phase. Therefore, our data suggest that oxytocin might hinder the restoration of trustworthiness and diminish risk-taking behavior when trust is violated, especially in those who are hormonally prone to risk-taking behavior by a high testosterone-cortisol ratio.

•

Oxytocin (32IU) was administered intranasally to healthy young males in a double-blind placebo-controlled study.

•

Testosterone-cortisol ratio was positively associated with trustworthiness during the Trust Game.

•

Oxytocin significantly attenuated the association between testosterone-cortisol ratio and trustworthiness.

Assessing Two Dimensions of Interpersonal Trust: Other-Focused Trust and Propensity to Trust

One’s propensity to trust others and others’ trustworthiness are two important aspects of interpersonal trust. Both theory and research suggest that it is possible to distinguish between an individual’s propensity to trust (one’s “trustingness” or the extent to which one feels able to trust others) and their other-focused trust (the extent to which one feels that others are worthy of our trust). However, there is as yet no measure that distinguishes between these two components of trust. In three studies, we examined the psychometrics of a proposed two-dimensional measure of trust that encompasses propensity to trust and other-focused trust components. To test discriminant validity, we also administered measures of personality, personal self-esteem, social capital, propensity to like people, perceived social support, as well as general and personal beliefs in a just world. Factor analyses supported the proposed two-factor model for the new trust measure. Further analyses supported the difference between these measures.

Uncovering Susceptibility Risk to Online Deception in Aging

OBJECTIVES

Fraud in the aged is an emerging public health problem. An increasingly common form of deception is conducted online. However, identification of cognitive and socioemotional risk factors has not been undertaken yet. In this endeavor, this study extended previous work suggesting age effects on susceptibility to online deception.

METHODS

Susceptibility was operationalized as clicking on the link in simulated spear-phishing emails that young (18-37 years), young-old (62-74 years), and middle-old (75-89 years) Internet users received, without knowing that the emails were part of the study. Participants also indicated for a set of spear-phishing emails how likely they would click on the embedded link (susceptibility awareness) and completed cognitive and socioemotional measures to determine susceptibility risk profiles.

RESULTS

Higher susceptibility was associated with lower short-term episodic memory in middle-old users and with lower positive affect in young-old and middle-old users. Greater susceptibility awareness was associated with better verbal fluency in middle-old users and with greater positive affect in young and middle-old users.

DISCUSSION

Short-term memory, verbal fluency, and positive affect in middle-old age may contribute to resilience against online spear-phishing attacks. These results inform mechanisms of online fraud susceptibility and real-life decision-supportive interventions toward fraud risk reduction in aging.

Intranasal administration of oxytocin decreases task-related aggressive responses in healthy young males

Aggression and distrust are often challenging problems in mental health treatment. Converging evidence reveals that oxytocin increases trust in social interactions and decreases fear of social betrayal. However, oxytocin has also been associated with protective behavior and, as such, might increase defensive aggressive reactions. In this randomized double-blind, placebo-controlled study, the effects of intranasal oxytocin (32IU) on task-related aggressive responses were measured using the Point Subtraction Aggression Paradigm (PSAP). Fifty-seven healthy males were enrolled and randomized to oxytocin (N = 30) or placebo (n = 27). Salivary oxytocin, cortisol and testosterone were measured serially prior to the intervention, and then before and after the PSAP, to evaluate the effects of oxytocin administration on hormonal functioning in relation to aggression. In addition, oxytocin was measured in urine collected directly after the experimental task, reflecting the 2 h period after oxytocin or placebo administration. The proportion of aggressive responses to the PSAP was significantly lower in participants receiving oxytocin versus placebo (β= -0.46, P = 0.01). No significant effect of oxytocin was found regarding defensive reactions. Urinary oxytocin was negatively associated with the proportion of aggressive responses to the PSAP in both the oxytocin and the placebo group (β= -0.02, P < 0.01), suggesting that higher levels of urinary oxytocin corresponded with reduced aggressive responding. Our results indicate that oxytocin administration reduces aggressive behavior in healthy young men. Moreover, increased endogenous urinary oxytocin is associated with less aggressive responding. Taken together, these findings suggest that oxytocin signaling has a causal influence on aggressive behavior.

Reliability and construct validity of 3 psychometric trust scales for women seeking substance abuse treatment in a community setting

Background: Women with a history of substance use disorder (SUD) constitute a unique population with gender-specific needs in treatment. Most notable is high rates of prior trauma and the need for a trauma-informed care framework. Given theoretical links between trauma and interpersonal trust, understanding quantitatively how trust may impact outcomes for women in this population requires confirmation of validity of existing psychometric instruments. Objective: This study sought to confirm reliability and construct validity of the Rotter Interpersonal Trust Scale, Wake Forest Trust in Physician Scale, and the Revised Health Care System Distrust Scale (RHCSDS) for use in women with a history of SUD seeking treatment in a community-based setting. Methods: A total of 301 participants were enrolled between August 2017 and March 2018 at an urban, community-based residential substance abuse treatment program in the mid-South. Participants were given an electronic survey containing questions about demographics/clinical characteristics, the Rotter, Wake Forest, and RHCSDS scales, Socially Desirable Response Five-Item Survey (SDRS-5), and the Adverse Childhood Experiences (ACEs) questionnaire. All participants also completed a modified protocol of the "Trust Game." Statistical analysis was completed for each trust scale in regard to scale means and distribution, internal consistency, interscale correlation, and scale correlation to the ACE score. Results: Results confirm statistically significant (P < .001) differences in global trust and trust of health care providers compared with general population samples in prior studies. Internal consistency of scales is comparable to reliability testing in prior studies (α > .70 for all scales). Interscale correlation between individual scales is statistically significant, with the strongest relationship between the 2 health care-specific scales (r = -.740, P < .001). There was a weak, negative correlation between the ACE score and interpersonal trust (r = -.135, P = .019). Individual scales do not have statistically significant correlation with "Trust Game" scores. Discussion: Findings suggest reliability and construct validity of scales for use in this population.

Toward an Understanding of Trust Repair in Human-Robot Interaction

Gone are the days of robots solely operating in isolation, without direct interaction with people. Rather, robots are increasingly being deployed in environments and roles that require complex social interaction with humans. The implementation of human-robot teams continues to increase as technology develops in tandem with the state of human-robot interaction (HRI) research. Trust, a major component of human interaction, is an important facet of HRI. However, the ideas of trust repair and trust violations are understudied in the HRI literature. Trust repair is the activity of rebuilding trust after one party breaks the trust of another. These trust breaks are referred to as trust violations . Just as with humans, trust violations with robots are inevitable; as a result, a clear understanding of the process of HRI trust repair must be developed in order to ensure that a human-robot team can continue to perform well after a trust violation. Previous research on human-automation trust and human-human trust can serve as starting places for exploring trust repair in HRI. Although existing models of human-automation and human-human trust are helpful, they do not account for some of the complexities of building and maintaining trust in unique relationships between humans and robots. The purpose of this article is to provide a foundation for exploring human-robot trust repair by drawing upon prior work in the human-robot, human-automation, and human-human trust literature, concluding with recommendations for advancing this body of work.

Psychometric properties of the Trust in Physician Scale in Tamil Nadu, India

CONTEXT

Trust in health care is of high intrinsic value. It also leads to positive outcomes such as better treatment adherence and disclosure of sensitive information. Therefore, there is a need to measure trust in health care objectively.

AIMS

To assess the psychometric properties of the Trust in Physician Scale in Tamil Nadu, India.

SETTINGS AND DESIGN

The study was conducted in a private tertiary hospital setting in Tamil Nadu by a cross-sectional survey design.

METHODS

The Trust in Physician Scale and General Trust Scale were administered to 288 participants in the waiting area of a tertiary care hospital in Tamil Nadu.

STATISTICAL ANALYSIS

Descriptive statistics, exploratory factor analysis, and Cronbach's alpha statistics were used to assess the validity and reliability of the scale.

RESULTS

The respondents were predominantly men from rural areas, older than 35 years of age, and with lesser than 8 years of schooling. The questionnaire had acceptable internal consistency with Cronbach's alpha of 0.707 (95% confidence interval 0.654-0.755). Exploratory factor analysis divided the questionnaire into four domains. Seven items loaded into factor 1 which explained dependability and competence of the physician, two items loaded on factor 2, and one each in factors 3 and 4. The latter four items had very low item to total correlations and hence did not contribute much to the questionnaire.

CONCLUSIONS

The Trust in Physician questionnaire needs to be modified to accurately measure the domains of trust in the context of the study area. More qualitative studies are required to understand the domains of trust in this cultural and social context.

Who Trusts? Personality, Trust and Knowledge Sharing

The strategic importance of knowledge sharing and its relationships with organizational and managerial (i.e. environmental) factors have been well documented. The effects of some context-specific individual factors—including interpersonal trust—on knowledge sharing have also been investigated. The effects of enduring and pervasive individual factors (i.e, personality) on knowledge sharing have not been adequately described empirically. This article links personality, specifically agreeableness, a broad personality domain and propensity to trust, a narrow personality facet, to knowledge sharing via interpersonal trust, thereby clarifying substantial person-related effects within these important workplace phenomena.

La confiance en marketing : Fondements et applications

L'objectif de cette contribution est de clarifier les statuts et les rôles émergents du concept de confiance en marketing et de caractériser sa diffusion dans la discipline. Pour cela, nous distinguerons deux plans d'observation : les domaines d'application et la “théorie générale” du marketing. Les applications du concept se sont multipliées dans le champ des échanges interentreprises : problématiques de vente et de négociation, et problŕmatique du canal (relations client-fournisseur et accords co-latéraux). Cette diffusion est indissociable de l'extension de la théorie générale vers le marketing relationnel mais dans ce plan, la définitíon de la confiance et la maîtrise de sa dynamique demeurent incertaines. En effet, sur le plan fondamental, la portée théorique du concept s'est traduite par un apport à la compréhension de la structuration des transactions mais l'approche psychologique de l'échange a engendré des paradoxes dans l'appropriation du concept par le marketing. En conclusion, il apparaît que la progression théorique de la discipline gagnerait à la prise en considération par les chercheurs, de la problématique du rapport entre la théorie de la satisfaction et la théorie de la confiance.

Vers un modèle qualité-satisfaction intégrant la confiance?

Cet article a pour but de montrer que la prise en compte de la confiance dans la marque permet de mieux comprendre les liens entre la qualité d'un produit ou d'un service et la satisfaction des consommateurs. La première partie est consacrée à l'étude des liens entre qualité, confiance et satisfaction, aboutissant à la proposition d'un modèle intégrant la confiance. Une recherche dans le domaine de la restauration rapide met en évidence dans la deuxième partie les relations existant entre l'expérience passée avec la marque, la confiance dans la marque, la qualité perçue et la satisfaction des consommateurs.

Development and Validation of the Behavioral Tendencies Questionnaire

At a fundamental level, taxonomy of behavior and behavioral tendencies can be described in terms of approach, avoid, or equivocate (i.e., neither approach nor avoid). While there are numerous theories of personality, temperament, and character, few seem to take advantage of parsimonious taxonomy. The present study sought to implement this taxonomy by creating a questionnaire based on a categorization of behavioral temperaments/tendencies first identified in Buddhist accounts over fifteen hundred years ago. Items were developed using historical and contemporary texts of the behavioral temperaments, described as “Greedy/Faithful”, “Aversive/Discerning”, and “Deluded/Speculative”. To both maintain this categorical typology and benefit from the advantageous properties of forced-choice response format (e.g., reduction of response biases), binary pairwise preferences for items were modeled using Latent Class Analysis (LCA). One sample (n₁ = 394) was used to estimate the item parameters, and the second sample (n₂ = 504) was used to classify the participants using the established parameters and cross-validate the classification against multiple other measures. The cross-validated measure exhibited good nomothetic span (construct-consistent relationships with related measures) that seemed to corroborate the ideas present in the original Buddhist source documents. The final 13-block questionnaire created from the best performing items (the Behavioral Tendencies Questionnaire or BTQ) is a psychometrically valid questionnaire that is historically consistent, based in behavioral tendencies, and promises practical and clinical utility particularly in settings that teach and study meditation practices such as Mindfulness Based Stress Reduction (MBSR).

Knowledge-centered culture and knowledge sharing: the moderator role of trust propensity

Purpose

– This research aims to evaluate if knowledge-centered culture (KCC) fosters knowledge sharing equally across employees with different levels of trust propensity, an enduring individual characteristic.

Design/methodology/approach

– A cross-sectional questionnaire study was conducted with 128 US-based employees.

Findings

– The authors found that KCC only promoted knowledge sharing in individuals with high levels of trust propensity. For individuals with low levels of trust propensity, KCC had no effect on knowledge sharing.

Research limitations/implications

– The authors focused exclusively on trust propensity as a moderator. Future research could analyze the role of other enduring individual differences in the relationship between KCC and knowledge sharing.

Practical implications

– A KCC may be inefficient in promoting knowledge sharing in employees with low propensity to trust. Recruitment and selection of individuals with a high propensity to trust is a possible solution to enhance the association between KCC and knowledge sharing in organizations.

Originality/value

– By identifying an enduring individual characteristic that shapes the relationship between KCC and knowledge sharing, the authors move toward the development of a contingent view of KCC and show that KCC fosters knowledge sharing differently across employees.

Explaining the relationship between insecure attachment and partner abuse: the role of personality characteristics

Studies have found that male batterers are more often insecurely attached as compared with nonbatterers. However, it is still not clear how insecure attachment is related to domestic violence. Many studies compared batterers and nonbatterers regarding pathological personality characteristics that are related to attachment (e.g., dependency, jealousy) and generally found that batterers report more personality characteristics. However, these studies did not investigate which role these characteristics played in the relationship between insecure attachment and battering. The first aim of this study is to test which personality characteristics are good candidates to explain the relationship between insecure attachment and domestic violence. The second aim is to test whether personality characteristics are predictive of battering over and above attachment. Seventy-two mainly court-mandated family-only males who were in group treatment for battering are allocated to a securely and an insecurely attached group and compared with 62 nonbatterers. Using questionnaires, self-esteem, dependency, general distrust, distrust in partner, jealousy, lack of empathy, separation anxiety, desire for control, and impulsivity were assessed. This was the first study that examined distrust, separation anxiety, and desire for control in relation to battering. The results show that the relationship between insecure attachment and domestic violence can be explained by separation anxiety and partner distrust. Moreover, only partner distrust increased the risk for battering over and above insecure attachment. The findings suggest the presence of two subtypes among batterers based on attachment style, which has similarities to the family-only and dysphoric-borderline subtypes suggested by Holtzworth-Munroe and Stuart. Implications of the present findings for therapy are discussed.

Beyond Criterion A1: the effects of relational and non-relational traumatic events

Trauma research has historically focused on Criterion A1 traumas, neglecting many other negative interpersonal events that have been shown to lead to posttraumatic stress disorder (PTSD; S. L. Anders, P. A. Frazier, & S. Frankfurt, 2011 ). Trauma research has also focused primarily on PTSD and neglected other important outcomes, such as relationship functioning. This study aimed to assess a broader range of events, including many Criterion A1 interpersonal events; assess the cumulative impact of event exposure; and examine the relation between event exposure and a broad range of outcomes, including relationship functioning. A sample of 181 undergraduate students completed measures assessing exposure to a broad range of events, their worst lifetime event, and current psychological (e.g., psychological distress) and relationship (e.g., partner trust) functioning. Results suggested that non-Criterion A1 relational events were very common in our sample. The number of lifetime relational events experienced, whether Criterion A1 or non-Criterion A1, was strongly and consistently associated with all outcomes. The number of lifetime Criterion A1 non-relational events experienced was significantly associated with current PTSD symptoms but was not associated with other mental health and relationship outcomes. No differences were found between Criterion A1 relational, non-Criterion A1 relational, and Criterion A1 non-relational worst events on any of the mental health or relationship measures. Implications for further research and interventions are discussed.

The Decision Making Individual Differences Inventory and guidelines for the study of individual differences in judgment and decision-making research

Individual differences in decision making are a topic of longstanding interest, but often yield inconsistent and contradictory results. After providing an overview of individual difference measures that have commonly been used in judgment and decision-making (JDM) research, we suggest that our understanding of individual difference effects in JDM may be improved by amending our approach to studying them. We propose four recommendations for improving the pursuit of individual differences in JDM research: a more systematic approach; more theory-driven selection of measures; a reduced emphasis on main effects in favor of interactions between individual differences and decision features, situational factors, and other individual differences; and more extensive communication of results (whether significant or null, published or unpublished). As a first step, we offer our database—the Decision Making Individual Differences Inventory (DMIDI; http://html://www.sjdm.org/dmidi), a free, public resource that categorizes and describes the most common individual difference measures used in JDM research.

Gender Distrust and Intimate Unions among Low-Income Hispanic and African-American Women

We investigate levels of generalized distrust of men among low-income African American, Mexican, Puerto Rican, Dominican, and non-Hispanic white women in a three-city survey. The results reveal substantial variation. We find Hispanics' overall levels of distrust to be higher than levels for either African Americans or whites. Among Hispanics, however, Dominicans are the most distrusting group followed by Puerto Ricans; whereas Mexicans report levels of distrust that are comparable to African Americans and non-Hispanic whites. Married women are less distrusting than cohabiting women who, in turn, are less distrusting than non-cohabiting women. Nevertheless, distrust is not a significant predictor of a woman's total number of lifetime marital and cohabiting relationships; and distrust only marginally predicts a woman's desire to be in a steady relationship. We suggest that studies of trust in this population should focus more on attitudes displayed in specific encounters than on overall, generalized attitudes about gender distrust.

The BRCA Self-Concept Scale: a new instrument to measure self-concept in BRCA1/2 mutation carriers

Genetic testing for BRCA1/2 has psychosocial impacts including those related to views of personal health, sense of self and identity and body image. The centrality of a person's self-concept in maintaining physical and psychosocial well-being has been well recognized; however, to date research exploring altered self-concept related to carrier knowledge is limited.

OBJECTIVE

The objective of the study was to develop and validate a scale to measure the self-concept among individuals testing positive for BRCA1/2 mutations.

METHODS

The study was conducted in two phases: phase I: item generation and refinement and phase II: scale selection and initial validation. During phase I, scale items were generated through individual interviews and focus groups of women with BRCA1/2 mutations, including women with or without a prior diagnosis of cancer. In phase II items were selected based on several criteria resulting in a 25-item scale, which underwent a reliability analyses and preliminary validation with 115 women. A second sample of 126 women was used to conduct further validation and samples were pooled to conduct factor analysis and the final scale selection.

RESULTS

A 17-item self-concept scale emerged having three factors: stigma, vulnerability and mastery demonstrating evidence for an instrument with promising psychometric properties (total scale alpha=0.90).

CONCLUSIONS

The scale has direct relevance for research in facilitating our understanding of the specific aspects of the self, which are vulnerable to BRCA1/2 testing and which play a role in clinical outcomes, to facilitate the development and specific testing of interventions and may be used as an outcome measure. Specific measurement tools for genetic populations will ultimately assist in the clinical management of these populations.

Mistrust of health care organizations is associated with underutilization of health services

PURPOSE

We report the validation of an instrument to measure mistrust of health care organizations and examine the relationship between mistrust and health care service underutilization.

METHODS

We conducted a telephone survey of a random sample of households in Baltimore City, MD. We surveyed 401 persons and followed up with 327 persons (81.5 percent) 3 weeks after the baseline interview. We conducted tests of the validity and reliability of the Medical Mistrust Index (MMI) and then conducted multivariate modeling to examine the relationship between mistrust and five measures of underutilization of health services.

RESULTS

Using principle components analysis, we reduced the 17-item MMI to 7 items with a single dimension. Test-retest reliability was moderately strong, ranging from Pearson correlation of 0.346-0.697. In multivariate modeling, the MMI was predictive of four of five measures of underutilization of health services: failure to take medical advice (b=1.56, p<.01), failure to keep a follow-up appointment (b=1.11, p=.01), postponing receiving needed care (b=0.939, p=.01), and failure to fill a prescription (b=1.48, p=.002). MMI was not significantly associated with failure to get needed medical care (b=0.815, p=.06).

CONCLUSIONS

The MMI is a robust predictor of underutilization of health services. Greater attention should be devoted to building greater trust among patients.

The FAP self-concept scale (adult form)

Familial Adenomatous Polyposis (FAP) is a dominantly inherited disorder characterized by multiple colorectal adenomas associated with a 100% risk of early colorectal cancer. A diagnosis of FAP may alter a person's self-concept, which in turn may impact on an individual's quality of life and screening behaviors.

PURPOSE

The purpose of the study was to develop and validate a scale for measuring the impact of being diagnosed with FAP on an individual's self-concept.

METHODS

The study was conducted in two phases: Phase (1) Item generation and refinement, and Phase (2) Scale selection and initial validation. Adults age 18 and older.

RESULTS

During Phase 1, scale items were generated through individual interviews and two professionally led focus groups. In Phase 2, 132/200 (66%) participants completed the 41-item candidate scale and a battery of standardized validating measures. The mean age of participants was 48 (12.2) years (range 21-74), 57% were female, 72% were married and 69% were Anglo-Canadian. The study resulted in a 23-item valid and reliable scale, Cronbach's alpha = .92, inter-item correlation = .34, total variance explained = 52.6%, low correlation with social desirability, and expected relationships with the other validating measures. Factor analysis resulted in three subscales representing the dimensions of stigma, self-esteem and mastery.

CONCLUSIONS

A promising new scale for measuring self-concept among adults with FAP has been developed. The instrument has potential use as a clinical screening tool and a research measure that will contribute to the empirical and theoretical literature.

Impact of racial perspectives and contextual variables on marital trust and adjustment for African American couples

This study examined the associations of racial perspectives that represent pro-African American, anti-African American, or a mixture of these beliefs with marital trust and adjustment for African American couples (N = 93). Religious well-being and socioeconomic status (SES) were examined as contextual moderators. For husbands only, the anti-African American perspective was inversely associated with couple functioning, the mixed perspective was inversely associated with marital trust, and the pro-African American perspective predicted marital trust only for husbands having relatively low religious well-being and relatively high SES. The limited effects of pro-African American attitudes suggest the need to evaluate a wider range of these attitudes in future research. Also, findings corroborate suggestions for therapists to routinely assess and address both cultural pride and shame issues relevant to African American couple relationships.

The development of a cognitive scale for functional bowel disorders

OBJECTIVE

The importance of psychosocial factors in patients with Functional Bowel Disorders (FBD) has been well-established. However, most psychosocial measures used in research with FBD patients were not designed or validated on this population. A recent international team report recommended that psychosocial measures be developed to increase our understanding and treatment of FBD. The purpose of this study was to develop a reliable and valid instrument designed specifically to assess cognitions of patients with FBD.

METHOD

An initial set of 204 scale items was generated from a large pool of thought diaries from patients diagnosed with FBD. Items were additionally refined using several methods, including consultation with a multidisciplinary team of international experts on FBD. The remaining 95 items were administered, along with a set of validating questionnaires, to a new sample of 75 FBD patients in Canada and the United States.

RESULTS

The findings indicate that the final 25-item scale has high reliability (Cronbach's alpha = .93; inter-item correlation = .36); high concurrent criterion validity evidenced by the correlation of the scale with a global rating of life interference caused by bowel symptoms (r = .71; p<.001); acceptable convergent validity evidenced by the correlation of the scale with the Dysfunctional Attitudes Scale (r = .38; p<.01); high content validity and face validity; and minimal social desirability contamination (r = .15; NS).

CONCLUSIONS

The Cognitive Scale for Functional Bowel Disorders is a valid and reliable scale that can be used as an outcome measure in evaluating the efficacy of different forms of psychotherapeutic intervention for FBD, and can also serve as a helpful assessment tool for health professionals working with patients diagnosed with FBD.
