An improved scale for assessing patients’ trust in their physician
Health Marketing Quarterly, 2001
Patients' trust in their primary care physician is a critical concept for healthcare practitioners and scholars. At the clinical level, such trust buttresses patient-physician treatment relationships; at the organizational level, such trust fosters enhanced organizational effectiveness and other positive outcomes. To empirically assess various trust-related issues on both levels, we develop a comprehensive, bi-dimensional trust scale specific to patient-physician relationships. Response analysis from two samples suggests that the scale's benevolence dimension comprises understanding patients' individual experiences, expressing caring, communicating clearly and completely, building partnership and sharing power, demonstrating honesty and respect, and keeping information confidential. The scale's technical competence dimension comprises evaluating problems thoroughly, providing appropriate and effective treatment, predisposing factors, and structural and staffing factors.
Assessment of Trust in Physician: A Systematic Review of Measures
PLoS ONE, 2014
Over the last decades, trust in physician has gained in importance. Studies have shown that trust in physician is associated with positive health behaviors in patients. However, the validity of empirical findings fundamentally depends on the quality of the measures in use. Our aim was to provide an overview of trust in physician measures and to evaluate the methodological quality of the psychometric studies and the quality of psychometric properties of identified measures. We conducted an electronic search in three databases (Medline, EMBASE and PsycInfo). The secondary search strategy included reference and citation tracking of included full texts and consultation of experts in the field. Retrieved records were screened independently by two reviewers. Full texts that reported on testing of psychometric properties of trust in physician measures were included in the review. Study characteristics and psychometric properties were extracted. We evaluated the quality of design, methods and reporting of studies with the COnsensus based Standards for the selection of health status Measurement INstruments (COSMIN) checklist. The quality of psychometric properties was assessed with Terwee's 2007 quality criteria. After screening 3284 records and assessing 169 full texts for eligibility, fourteen studies on seven trust in physician measures were included. Most of the studies were conducted in the USA and used English measures. All but one measure were generic. Sample sizes range from 25 to 1199 participants, recruited in very heterogeneous settings. Quality assessments revealed several flaws in the methodological quality of studies. COSMIN scores were mainly fair or poor. The overall quality of measures' psychometric properties was intermediate. Several trust in physician measures have been developed over the last years, but further psychometric evaluation of these measures is strongly recommended. The methodological quality of psychometric property studies could be improved by adhering to quality criteria like the COSMIN checklist.
The health care relationship (HCR) trust scale: Development and psychometric evaluation
Research in Nursing & Health, 2006
A sequential multi-method approach using focus groups, individual interviews, and quantitative instrument development procedures was used to develop and evaluate a scale to measure patient trust in health care providers (HCPs). The resulting 15-item Health Care Relationship (HCR) Trust Scale was tested for internal consistency, test-retest reliability, and construct validity. The Cronbach alphas were .92 (time 1) and .95 (time 2), respectively. Test-retest reliability was .59 (p < .01). The HCR Trust Scale did not correlate with the Marlowe-Crowne Social Desirability Scale (r ¼ .20, p ¼ .07) or the Rapid Estimate of Adult Literacy in Medicine scale (r ¼ À.21, p ¼ .13). Principal component factor analysis with varimax rotation revealed a three-factor solution that explained 69% of the estimated common variance in the HCR trust scale. Cronbach alphas for the 3 factors ranged from .81 to .89. Findings of this study support the use of the HCR Trust Scale for measuring trust in various HCPs by diverse patient populations. More work is needed to test the usefulness of the scale with a greater number of patients and in other chronic illness populations.
Psychometric properties of primary health care trust questionnaire
BMC Health Services Research, 2019
Background: Trust has been introduced as the cornerstone of the public and health providers' relation. Public trust in primary health care (PHC) is crucial and must be measured. The aim of this study was to develop and validate PHC trust measurement tool. Methods: This was a psychometric study to develop PHC trust measuring tool done in Tabriz, East-Azerbaijan with participation of 600 households in 2016. Item generation was done through literature review and experts opinions. The content validity, reliability and construct validity of the PHC trust tool were assessed using several statistical methods including modified Kappa, Kendall's Tau and intra-class correlation coefficient (ICC) as well as exploratory factor analysis (EFA). Data were analyzed using STATA 14 statistical software package. Results: A 30-item questionnaire was developed. The Modified Kappa coefficient as an indicator of content validity assessment was 0.94. With respect to reliability assessment, a high internal consistency was observed with 0.98 Cronbach-Alpha score and the test-retest reliability for overall scale (assessed by ICC) was 0.94 (CI: 0.87-0.97). Exploratory factor analysis emerged 2 factors. Factor 1 consisted of 25 items accounting for 74.1% of the variance (eigenvalue = 22.47) followed by Factor 2 consisting of 5 items accounting for 19.2% of the variance (eigenvalue = 1.6). Conclusion: PHC trust measuring tool could be used as a valid and reliable tool by health systems in Iran and similar contexts to investigate how they are trustful from the public viewpoint.
Determinats of Trust in Medical Personal
Although research of the public’s trust in doctors is burgeoning, little attention has been given to examining how much trust is professed for other medical personnel, beyond doctors. This is a salient issue given the increase in patients’ clinical time with auxiliary medical staff. Using logistic regression techniques, we analyzed data from the 2008 Survey of Quality of Life in Arkansas to identify predictors of trust in doctors, other medical personnel, and medical personnel of different racial or ethnic back-grounds among Latinos and non-Hispanic White respondents. Results indicate that health insurance coverage was the most consistent predictor across multiple measures of trust in medical personnel. However, race and ethnicity and citizenship status of the respondents were more salient. Implications and future research are also discussed in this article.
Patient Trust: Is It Related to Patient-Centered Behavior of Primary Care Physicians
Medical Care, 2004
Background: Patients' trust in their health care providers may affect their satisfaction and health outcomes. Despite the potential importance of trust, there are few studies of its correlates using objective measures of physician behavior during encounters with patients. Methods: We assessed physician behavior and length of visit using audio tapes of encounters of 2 unannounced standardized patients (SPs) with 100 community-based primary care physicians participating in a large managed care organization. Physician behavior was assessed via 3 components of the Measure of Patient-Centered Communication (MPCC) scale. The Primary Care Assessment Survey (PCAS) trust subscale was administered to 50 patients from each physician's practice and to SPs. We used multilevel modeling to examine the associations between physicians' Patient-Centered Communication during the SP visits and ratings of trust by both patients and SPs. Results: Component 1 of the MPCC, which explored the patient's experience of the disease and illness, was independently associated with patient's rating of trust in their physician. A 1 SD increase in this score was associated with 0.08 SD increase in trust (95% confidence interval 0.02-0.14). Each additional minute spent in SP visits was also independently associated with 0.01 SD increase in patient trust. (95% confidence interval 0.0001-0.02). Component 1 and visit length were also positively associated with SP trust ratings. Conclusions: Physician verbal behavior during an SP encounter is associated with trust reported by SPs and patients. Research is needed to determine whether interventions designed to enhance physicians' exploration patients' experiences of disease and illness improves trust.
Development and testing of a scale to measure trust in the public healthcare system
Trust is an important factor in improving the performance of the healthcare system. This study aimed to develop a validated scale to measure trust in the public healthcare system. We adopted a sequential exploratory mixed study design, with developmental and testing phases. In the developmental phase, the construct of " healthcare system trust " was conceptualised and items were generated on the basis of information from a review of the literature on trust, in-depth interviews and a review of other scales. Exploratory factor analysis was employed for item reduction. In the testing phase, the reliability and validity measures were established. The face validity, content validity and construct validity of the scale were assessed. The final scale was a Likert-type scale with 23 items, 16 of which measured trust in the healthcare providers and 7, in healthcare institutions. The scale is a valid and reliable tool for measuring trust in the public healthcare system.
