Summary
Objective
The objective of this study was to examine patient–provider relationships among American Indians and Alaska Native (AI/AN) patients by examining associations between patient activation, perceived provider weight bias and working alliance. Patient activation is generally defined as having the knowledge, skills and confidence to manage one's health.
Methods
Among a sample of 87 AI/AN adults presenting for general medical care at an urban clinic in the north‐west region of the USA, ordinary least squares regression analysis was completed to examine associations.
Results
Better working alliance scores were associated with increased patient activation, while perceived provider weight bias was associated with reduced patient activation. In addition, those with class II obesity had decreased patient activation.
Conclusion
These findings point to the importance of a positive patient–provider relationship in AI/ANs. Optimal patient engagement and subsequent health outcomes warrant additional consideration of patients' perceptions of provider weight bias within the context of health promotion and interventions.

Introduction
Based on population surveillance studies, 70% of American adults have a body mass index (BMI) that would classify them as having overweight or obesity 1. Based on these population‐level studies, it is conceivable that many adults who fall within this BMI range may have clinical obesity requiring clinical support and care. However, at the individual level, clinical diagnosis by a qualified healthcare professional is required. Although obesity is a growing concern for all groups, American Indians and Alaska Natives (hereinafter AI/ANs) experience higher burdens of obesity compared with non‐Hispanic Whites 2, 3, as well as pronounced disparities for obesity‐related diseases such as type 2 diabetes and cardiovascular diseases 4, 5. Obesity is a chronic disease 6 that can be treated, and its sequelae prevented, through comprehensive care plans, including behaviours that result in weight loss and weight management 7. Success in adhering to therapeutic goals for obesity has been marginal at best in the general population 8; similar outcomes have been observed for AI/ANs 9. Because obesity is a major cause of disability and mortality among AI/ANs, and contributes to significant and increasing healthcare costs 10, it is imperative that comprehensive interventions consider factors that influence desired health outcomes.
There is growing recognition that treating and managing chronic disease, such as obesity, requires health programming that considers health determinants more broadly by reaching beyond individual‐level factors 11, 12, 13, 14. For example, healthcare providers have a critical role in assessing and recommending comprehensive treatment plans for obesity, as well as engaging patients to improve health outcomes by promoting behavioural changes. Studies, including research completed by Sabin et al., consistently show that some providers hold a strong weight bias 15, 16, 17, which refers to negative attitudes towards others because they have overweight or obesity 17, 18. Clinical judgment and recommendations may be shaped by these negative beliefs and reduce the quality of health care as well as compromise the patient–provider relationship 11. Such experiences may also diminish patient engagement, which is integral to interventions that are designed to support patients towards managing their health 19.
With the exception of the recent study by Sabin et al. 20, which examined weight bias within the healthcare context as reported by providers – unlike this study, which examines perceived provider bias reported by patients – no other studies of this issue have been conducted among AI/ANs. However, previously published studies that included AI/ANs and examined other forms of bias in health care (such as perceived race‐based discrimination during the clinical encounter) have documented that such perceptions are associated with a greater degree of patient disengagement and that individuals reporting perceived discrimination have poorer clinical measures and more unmet need for preventive services than those reporting none 21, 22, 23. Therefore, given the paucity of this research, more work is needed to understand different forms of discrimination, including weight‐based discrimination, in relation to healthcare and health disparities among AI/ANs.
The patient–provider relationship has also been associated with patient activation, defined as having the knowledge, skills and confidence to manage one's health 20, 24. Among populations with chronic disease 25 and Latinos 10, 26, increased patient activation has been associated with patients reporting positive and quality interactions with their healthcare provider. Patient activation has also been associated with health outcomes. For example, studies in diverse groups of patients with chronic disease have documented that higher patient activation correlates with greater success in practicing self‐management behaviours 24, 25, 27. There is some evidence that patients with a higher level of activation also incur lower healthcare costs than patients with a lower level of activation 28, 29. Patient activation has particularly significant implications for conditions – such as obesity – that require a high level of patient effort and self‐management to achieve desired therapeutic goals 10, 24. While patient activation is a critical attribute of improved health outcomes, no prior studies have been conducted specifically among AI/ANs.
Therefore, this study examines the association between the patient–provider relationship, patients' perception of provider weight bias and patient activation among a sample of AI/AN patients presenting for general clinical medical care at an urban clinic located in the north‐west region of the USA. Because the sample size is small and this study is one of the first to explore the patient–provider relationship, provider bias and patient activation among any population, patients of all BMI strata are included. This study explores the unique contribution of the overall patient–provider relationship and perceived provider weight bias to patient activation. It is hypothesized that perceived higher quality patient–provider relationship will be associated with higher patient activation and perceived provider bias will be associated with lower patient activation.
Methods
Research setting
This study collected data in 2012 from 150 patients at a well‐established, non‐profit urban community health centre that provides medical, dental, mental health, nutrition, outpatient chemical dependency and traditional Native health care to AI/AN and non‐Native patients living in the Northwestern USA. The centre offers medical services Monday–Friday, with type of service (general care, specialty) varying by day. Urgent care is offered on a limited basis. Medical staff (medical doctors, provider assistants, nurse practitioners and medical residents) are mostly non‐Native and participate in regular on‐site cultural competency and proficiency training in the care of AI/ANs. Each year, approximately 7,000 patients receive medical care at this facility. Two‐thirds of these patients are AI/AN, representing over 200 federally recognized tribes.
Participant eligibility criteria for the study were (i) at least 18 years of age; (ii) able to speak and read English; (iii) having made at least two previous visits to the health centre within the year prior to survey administration; and (iv) able to provide informed consent. Participants were recruited in the following ways. Upon check‐in, patients presenting for general medicine clinic received an informational flyer about the study. At the end of their medical appointment, patients were invited to meet with the research staff to confirm eligibility criteria. Prior to data collection, informed consent was obtained, and all data collection methods and materials were administered in English. This study did not assess the type of care for which patients presented or restrict the two visits to the health centre to the same healthcare provider. Participants received a $15 gift card to a local grocer. The privacy committee of the health centre, Institutional Review Boards of the Portland Area Indian Health Service, Portland State University, and the University of Colorado Denver, all provided approval to conduct this study, as well as for the study protocol.
Measures
Dependent variable
Patient activation, measured using the Patient Activation Measure (PAM) 13‐item short form, was the outcome of interest 30. The short form has shown adequate reliability and validity in diverse groups 30, 31, 32. The PAM has been administered to AI/AN populations, although findings of these studies have not been published in peer‐reviewed journals (Craig Swanson, PAM, personal communication). Within this sample, this scale exhibited excellent internal consistency, with a Cronbach's alpha coefficient of 0.91. The average inter‐item correlation for these 13 items was 0.45. Example scale items included the following: ‘When all is said and done, I am the person who is responsible for managing my health’ and ‘Taking an active role in health care is the most important factor in my health’. Participants responded to each item on a 4‐point scale (1 = strongly disagree, 2 = moderately disagree, 3 = moderately agree and 4 = strongly agree) about statements referring to their role in their health care. Responses to all 13 items were averaged to produce an index of patient activation ranging from a minimum of 1 to a maximum of 4, with 1 indicating minimal patient activation and 4 indicating maximum patient activation.
Independent variables
Primary independent variables reflected factors that influence quality of care and thus included working alliance and patients' experiences of perceived provider weight bias in health care.
Working alliance was assessed using the Physician–Patient Working Alliance Scale 33, a 12‐item inventory composed of three domains: goals of treatment, shared tasks needed to reach goals and emotional bond. The Physician–Patient Working Alliance Scale, adapted by Fuertes et al. 14, is based on Tracy and Kokotovic's short C‐Working Alliance Inventory 34. It was developed to assess patients' perspectives on their relationship with their physician, and it has been shown to have excellent psychometric properties among a diverse sample of individuals 33. This scale had not been administered previously to AI/ANs. In this sample, this scale exhibited excellent internal consistency reliability, with a Cronbach's alpha of 0.94; the average inter‐item correlation for these 12 items was 0.56. A sample item from the scale was ‘My doctor and I agree on my treatment plan’. Responses to questions ranged from ‘strongly disagree’ to ‘strongly agree’ (values of 1–5). One of the 12‐scale items, ‘My doctor and I have different ideas about my medical problems’, was reverse coded prior to creating the scale, to ensure that higher scores reflected better outcomes. The index represents the average of all responses, with higher scores reflecting positive outcomes.
Perceived provider weight bias was assessed with a nine‐item measure reflecting the frequency of patients' perceived negative interactions with their providers concerning their weight 35. This measure has been administered in a racially diverse sample 35, but to our knowledge has not previously been administered to AI/ANs. Within this sample, this scale exhibited excellent internal consistency reliability, with a Cronbach's alpha coefficient of 0.94, and the average inter‐item correlation for these nine items was 0.64. Patients were asked a battery of questions, including ‘When I lost weight and regained it, doctors criticized me for not trying harder’ and ‘Doctors have said critical or insulting things to me about my weight’. The measure was scored on a 5‐point scale with the following response categories: 1 = never, 2 = rarely, 3 = sometimes, 4 = most of the time and 5 = always. The responses to these items were averaged, and higher values reflect a higher level of perceived provider weight bias.
This study further examined the association of BMI with patient activation. Research staff measured height and weight on site, and BMI scores were used to create a dichotomous measure for patients with obesity, with those in the normal/average and overweight range (≤29.99) equal to 0 and those with class I–III (30.00–34.99) (≥30.00) equal to 1. Finally, to control for the effects of known covariates, this study included age (18–49, 50–64, 65 years or higher); gender (male or female); level of education (≤high school, high school graduate/GED, some college, college degree or higher); employment status (unemployed, employed part‐time, employed full‐time or retired); and marital status (married, living with partner, separated/divorced/widowed or never married).
Analysis
The initial sample included responses for 150 patients from different racial and ethnic backgrounds. To specifically target outcomes among the AI/AN respondents, analysis was limited to those patients who identified as such (n = 88). Analysis was further restricted to those who provided valid responses on the variable of interest (patient activation), resulting in an analytic sample of 87. Bivariate associations between patient activation and covariates were examined. Patient activation was then modelled using ordinary least squares regression. Patient activation is a numeric index; therefore, ordinary least squares regression was the appropriate technique for conducting analyses to assess the accuracy of working alliance and perceived provider weight bias in predicting patient activation. Patient activation levels may vary by obesity status, and prior literature has shown variations in the quality of the patient–provider relationship according to weight status 11, 36. However, no significant interactions were detected. All analyses were performed using stata 14.0 (StataCorp. 2017. Stata Statistical Software: Release 15. College Station, TX: StataCorp LLC).
Results
Descriptive statistics are reported in Table 1. The sample included a total of 87 AI/AN patients. Across these patients, the average level of patient activation was 3.30, which is a relatively high level. The mean working alliance score was 3.45 for the group (higher scores indicate a higher quality relationship with provider), while the mean level of perceived provider weight bias was 1.45 (meaning provider weight bias was rarely perceived among this group). Those with BMIs in the normal (20.00–24.99) to overweight (25.00–29.99) range represented 50% of the sample (n = 44). Those with BMIs of 30.00–34.99 represented 25% of the sample (n = 22), and those with BMIs of 35.00 or higher represented 25% of the sample; thus combined, this group represented 50% of the sample. Half (50%) of patients were in the lowest age category of 18–49 years. With respect to education, the largest percentage reported a high school level (39.77%). More than half reported being unemployed (52.67%). A greater percentage of female participants were represented overall (62.5%). Finally, the majority of patients reported being either widowed/divorced/separated or single (41.38% and 28.74%, respectively).

Table 2 presents the results of bivariate analyses of the relationship between the independent variables of interest and the dependent variable, patient activation. Both variables of interest, working alliance and perceived provider weight bias, evidenced significant correlations with the outcome. Specifically, working alliance had a strong, positive relationship with patient activation. In other words, higher (or better) scores on working alliance were associated with higher patient activation scores. On the other hand, a strong, negative correlation was observed between patients' perception of provider weight bias and patient activation. In fact, patients who perceived any level of weight bias from healthcare providers had significantly lower levels of patient activation (mean = 3.10) compared with those reporting that they never perceived any weight bias (mean = 3.50).

The results of the regression analyses are shown in Table 3. Model 1 presents the association of working alliance and perceived provider weight bias with patient activation; model 2 incorporates all covariates (BMI category, age, education level, employment status, gender and marital status). Here, it is observed that both working alliance and perceived weight bias evidence significant associations with patient activation. The full model (model 2) indicates that the impact of working alliance on patient activation retained significance despite the inclusion of covariates. Formally, after adjusting for other factors, a one‐unit increase in working alliance score was associated with a 0.271‐unit increase in the patient activation score. With respect to perceived provider weight bias, a significant negative association with patient activation was observed prior to adding covariates. Accordingly, a one‐unit increase in perceived provider weight bias was associated with a −0.207‐unit decrease in the patient activation score. However, this particular association was diminished to marginal significance with the inclusion of other factors (p ≤ 0.10). Among the sociodemographic characteristics, it was observed that age was associated with patient activation such that being in the middle age range was associated with decreased patient activation. The covariates were not significantly associated with patient activation.

Discussion
This study found that a favourable patient–provider relationship, as perceived by the patient and measured by working alliance, had a statistically significant and positive association with patient activation among this sample of AI/ANs. This finding was expected and is consistent with those reported previously among other groups 25. Therefore, positive patient–provider relationships may represent a promising means through which to increase patient activation among AI/ANs and improve their health outcomes. Indeed, one of the most important features of the patient–provider relationship is the concept of working alliance, a collaborative partnership that encompasses agreement on explicit goals of treatment and tasks, and the degree of trust and bonding 23, 24. A strong working alliance is key to activating patients and fostering greater engagement in healthcare processes, including treatment adherence and retention 28, 29, 30, 31, 32. Some studies have shown that interpersonal factors that emerge during the medical encounter may strongly influence the extent to which patients adopt and sustain healthy behaviours for prevention, including secondary conditions of obesity 11, 30. For example, our previous work among AI/ANs with type 2 diabetes who were participants in a cardiovascular risk reduction programme described the important role of a participatory medical model with regard to mitigating mistrust and promoting engagement and retention and discussed several culturally based strategies to ensure strong engagement and retention in health interventions that may be important to AI/ANs and useful for programmes that target other diverse populations as well 37. Currently, programmes to support patients towards activation and engagement are not well developed or are lacking in availability 24, 38, and these resources are particularly scarce for AI/ANs. Therefore, future research into these issues is urgently needed.
To further understand associations between patient–provider interpersonal factors and patient activation, this study considered specific perceptions of provider weight bias according to patient experience. Patients' perceptions of provider weight bias in the patient–provider interaction were found to have a statistically significant negative association with patient activation, although the association was reduced to marginal significance with the inclusion of covariates. Again, based on the published research, this finding was expected 11.
Nonetheless, exploring provider weight bias among AI/ANs promises to be a fruitful line of inquiry. The available evidence suggests that provider bias may influence treatment of patients with obesity and that patients' perceived experiences of provider weight bias may undermine patient engagement. For example, several studies show that people with obesity have low rates of weight‐related counselling 12, 13, 14, 15, 16, 17, are less likely to undergo age‐appropriate preventive cancer screenings 12, 13, 14, 15 and receive less time and less frequent intervention from medical providers in the clinical setting than patients without obesity 16, 17. Among AI/ANs, weight bias in the context of health care has not been fully characterized. The one published study of these issues found that provider weight bias does not negatively contribute to the quality of care and obesity treatment for AI/AN patients 18. However, that study assessed weight bias from the point of view of the healthcare provider and not from the perspective of the patient. AI/AN patients may also have unique concerns related to the level of culturally responsive care received from non‐Native providers 37, 39.
This study found that the perception of a positive overall relationship and the perception of provider weight bias can co‐exist within the same patient–provider interaction. In our view, this finding warrants further examination, as it may have profound implications for healthcare and obesity interventions in the following ways. First, when patients with obesity report positive patient–provider relationships overall, providers and investigators may assume that weight bias was not experienced. The co‐existence of perceived positive relationships and perceived weight bias in this study indicates that this may be a false assumption. The operation of perceived provider weight bias may be masked by patients' reports of positive patient–provider relationships, and the positive patient–provider relationship may not benefit patients with obesity in the way it benefits other patients – especially patients who are classified as having severe obesity or being AI/AN and having obesity. This finding may be due to internalized weight bias among patients with obesity, which could lead those patients to mentally justify the weight‐biased attitudes and negative assumptions they perceive coming from the healthcare provider and the medical neglect that may result. These findings may also apply to AI/ANs 40, 41. The current understanding of these relationships remains undefined and deserves further clarification.
Finally, in this sample of AI/AN patients, it was observed that approximately half of the sample reported some level of perceived weight bias. It is important to note that these data were collected from a culturally centred healthcare programme that primarily serves AI/ANs, where providers have undergone cultural responsiveness training. This finding that approximately half of the patients reported some level of weight bias suggests that provider bias may be present even within a healthcare context that is positive in other ways. As such, this represents an area in need of improvement with respect to the development of models of culturally centred care.
Patients belonging to racial and ethnic minority groups may have unique concerns, arising not from isolated incidents but from structural inequities, that can be addressed by culturally responsive care 37. This may be particularly important in AI/AN healthcare settings, in which providers are typically non‐Indian and serve AI/AN patients. Cross‐racial and cross‐cultural clinical encounters are part of a broader societal trend wherein AI/ANs navigate systems in which they possess less political, economic and social power. Similarly, issues of weight bias are macro‐level issues that transcend the micro level of interpersonal interaction 17. Thus, examining the patient–provider relationship from a sociocultural perspective may help providers to cultivate stronger relationships with their patients and to understand how broader societal messages can be at work in patient experiences and healthcare decisions 22, 37, 39, 42.
These findings recommend that providers and healthcare organizations consider how patient perceptions of provider weight bias may occur and how provider weight bias may be playing a role in working alliance and patient activation. Closer examination of provider weight bias in the healthcare setting may also elucidate barriers to addressing inequities that characterize the quality of health care for AI/ANs. Such information will be useful to inform the design of prevention and intervention programmes that are relevant to the healthcare experiences of AI/ANs and may be useful to help support patients towards activation for optimum obesity management and health improvement. Future work into these issues may consider other fields such as mental health and diabetes, where the quality of the patient–provider interaction is well recognized as central to engagement processes and subsequent health outcomes 43, 44, 45, 46.
The potential limitations of this study are as follows. First, an inherent limitation in a cross‐sectional analysis is the inability to infer causality or temporality of associations. However, the results of these analyses align with prior work that suggests a positive association between working alliance and patient activation, and a negative association with weight bias, and thus contribute to the expanding body of literature documenting these associations. Second, there are possible limits to the generalizability of these findings. The study sample was drawn from a healthcare clinic, the services and resources of which may differ from those offered by other Indian healthcare facilities, such as smaller service units, programmes managed by the Indian Health Service and tribes and programmes located in rural areas. However, this study's analyses revealed relationships that were consistent with previously published studies of patient activation among non‐AI/AN groups. Third, because data were collected from a convenience sample of patients, selection bias may influence reported outcomes. For example, the sample may over‐represent patients able to take time after a medical appointment to participate in the study. Fourth, the design of the participant survey may further influence these findings. While the participants were recruited from general medical clinic days, the type of care patients were presenting for was not assessed; nor was the intersection between cultural differences and body size ideals and preferences among participants or their providers taken into account. Also, while the survey instructed participants to consider working alliance and weight bias with regard to their primary care provider, it is possible that respondents answered the items in reference to different types of providers they may have encountered, especially given the range of specialties offered at the participating healthcare facility. Finally, data were drawn from measures with previously unknown psychometric properties among diverse groups, including AI/AN populations. Additionally, the PAM‐13 scale is lacking a neutral option for participants to consider, which may limit its ability to fully capture patient perceptions. However, the measures employed here exhibited acceptable validity and reliability consistent with prior studies. These findings contribute to the body of literature on research instruments that may be useful among AI/AN populations. Future research among AI/ANs may consider performing additional analyses to further examine the psychometric properties of the respective measures used in this study. Such information will ameliorate a significant and persistent gap in the current understanding of their performance characteristics.
The findings reported herein suggest several opportunities for further investigation. Importantly, among a sample of AI/AN patients, the perception of a positive patient–provider relationship was associated with increased patient activation. The positive association of working alliance remained strong and statistically significant after adjustment for a number of covariates. Thus, a strong working alliance may represent an important means through which to improve the overall health of AI/AN populations. On the other hand, the perception of weight bias was associated with decreased patient activation (although the association was reduced to marginal significance with the inclusion of covariates). This study was limited by its smaller sample size, but given prior work documenting the importance of this factor and the fact that the association was approaching significance, this may merit more in‐depth investigation. Although beyond the scope of these data, the presence of weight bias within a setting that has been designed to be culturally responsive suggests the importance of future research into the effect of weight bias on the patient–provider relationship, the possible role of internalized weight bias and the buffering influence of culturally responsive care. These findings further substantiate and support broader calls to reduce weight bias among healthcare professionals 47, the need to develop evidence‐based obesity interventions that do not encourage weight bias 48, and to understand the role of internalized weight bias and culturally responsive care.
