Abstract
Clinical empathy has been studied in a number of health-care disciplines suggesting that higher practitioner empathy leads to improved patient health and wellness and improved patient outcomes. While some aspects of the physical therapist–patient relationship have been described, evidence of quantitative assessment of clinical empathy in physical therapists is scarce. To investigate the level of self-reported clinical empathy in physical therapists and its relationship to practice environment and workplace engagement, the Jefferson Scale of Empathy-Health Provider version (JSE-HP) and the Oldenburg Burnout Inventory (OLBI) were used. Study participants were 123 physical therapists working full time at either an acute care setting, a rehabilitation hospital, or an outpatient clinic. These physical therapists demonstrated a mean JSE-HP score of 118.5 (9.1) and a mean OLBI score of 15.63 (3.5). This mean empathy score was found to be higher than reported empathy level of some health disciplines such as nursing and pharmacy yet lower than others such as mental health workers, psychiatrists, and pediatricians. Practice setting was not found to be a significant factor regarding empathy levels in physical therapists. As reported in previous studies, there was a positive correlation between being female and having higher empathy levels. A positive correlation was found between age and work disengagement. Finally, our hypothesis regarding a negative correlation between empathy and work disengagement was confirmed, suggesting that workplace disengagement may diminish a physical therapist’s empathy, which may then negatively affect patient clinical outcomes.
Background
Clinical empathy has been defined as “a predominantly cognitive attribute that involves an understanding of the patient’s experiences, concerns, and perspectives, combined with a capacity to communicate this understanding and an intention to help” (M. R. Hojat, 2007; Thomas Jefferson University, 2018). The importance of clinical empathy in health care is supported by vast amounts of research regarding this attribute.
Clinical empathy has been studied in a number of health-care disciplines for its ability to enhance patients’ health and wellness. For example, physicians’ clinical empathy is linked to improved patient compliance with medical care (M. Hojat et al., 2011; Kim, Kaplowitz, & Johnston, 2004), better patient satisfaction (M. Hojat et al., 2010; Kim et al., 2004), and enhanced patient outcomes (Canale et al., 2012; M. Hojat et al., 2011; Rakel et al., 2009). Empathy has been found to be important in the nursing profession as well and has been linked with decreased anxiety and depression in patients undergoing cancer care (La Monica, Wolf, Madea, & Oberst, 1987). Studies that quantitatively measure self-reported empathy in physical therapists are limited, yet it is known that the positive working alliance between physical therapist and patient results in improved treatment adherence, satisfaction, physical functioning, and decreased depression in selected patient populations (Hall, Ferreira, Maher, Latimer, & Ferreira, 2010). In a qualitative study, Kidd, Bond, and Bell (2011) stated that patients receiving outpatient physical therapy considered a patient-centered approach, including caregiver empathy, to be important to their care. Peiris, Taylor, and Shields (2012) found patients participating in physical therapy at a rehabilitation hospital reported patient–therapist interactions, including empathy, motivation, and encouragement, were more important than the amount and content of physical therapy received.
Another area of study regarding clinical empathy delved into varying levels of clinical empathy present in different practice environments. Physicians practicing in outpatient settings were found to be more empathetic than physicians in an inpatient setting (Chaitoff et al., 2017). Studies in clinical nursing also found empathy levels varied in different settings such as emergency room and intensive care units (Bourgault et al., 2015; Gosselin, Bourgault, & Lavoie, 2016). Exploration of clinical empathy in the physical therapy profession across clinical settings has not yet been studied.
The relationship between clinical empathy and burnout has also been studied extensively in a variety of health-care disciplines. A systematic review by Wilkinson, Whittington, Perry, and Eames (2017) demonstrated a strong inverse correlation between empathy and the depersonalization component of burnout as well as a strong positive correlation between empathy and the personal achievement component of burnout. While burnout rates have been reported in physical therapy (Balogun, Titiloye, Balogun, Oyeyemi, & Katz, 2002; Campo, Weiser, & Koenig, 2009; Donohoe, Nawawi, Wilker, Schindler, & Jette, 1993; Schuster, Nelson, & Quisling, 1984), the relationship between empathy and burnout has not been investigated specifically.
The purposes of this study were to investigate clinical empathy in the physical therapy profession and its relationship to practice setting and work disengagement, a component of burnout. The researchers’ three hypotheses were (1) physical therapists will report levels of empathy similar to the levels reported by other patient-oriented health-care professionals, (2) there will be differences in self-reported empathy between practice settings, and (3) there will be an inverse relationship between self-reported levels of empathy and work disengagement.
Method
This study used a cross-sectional between-subjects casual-comparative design that gathered quantitative data from survey results. Institutional review board approval was obtained in May 2017.
Participants
A convenience sample was obtained, including 123 physical therapists from six sites in Massachusetts and Rhode Island: Beth Israel Deaconess Medical Center, Spaulding Rehabilitation Hospital Charlestown, Boston University Physical Therapy Center, and Southcoast Hospital Group. Two sites characterized as acute care hospitals, three sites as outpatient clinics, and one as an inpatient rehabilitation hospital. All full-time physical therapists working at these institutions were eligible to participate. All therapists given the survey completed the survey.
Instruments
This study used the Jefferson Scale of Empathy–Health Professional (JSE-HP), the work engagement portion of the Oldenburg Burnout Inventory (OLBI), and a short demographic survey. The JSE-HP was used for measuring self-reported levels of empathy among physical therapists. The JSE was originally developed to measure empathy in physicians and medical students (M. Hojat et al., 2001). A revised version was later developed for health professionals, referred to as the JSE-HP, which includes 20 questions answered on a 7-point Likert-type scale, with items equally split between positively and negatively worded items. Total scores range from 20 to 140, with higher scores indicating a greater level of empathy. Internal consistency reliability (Cronbach’s α) on JSE-HP has been reported between .81 and .89 (M. Hojat et al., 2002; M. Hojat et al., 2001). Test–retest reliability coefficient for JSE- HP has been reported as r = .65 with 3- to 4-month interval between testing (M. Hojat et al., 2002).
The OLBI was used to measure clinicians’ level of work disengagement. The OLBI is composed of two subscales that represent two core dimensions of burnout: Exhaustion and Work Disengagement, which can be used together or separately according to the developer (Demerouti, Mostert, & Bakker, 2010). In considering the use of the Exhaustion subscale, a weak negative correlation had been reported between empathy and emotional exhaustion (Wilkinson et al., 2017; Yuguero, Ramon Marsal, Esquerda, Vivanco, & Soler-González, 2017). Also, the Exhaustion subscale of the OLBI includes emotional and physical components of exhaustion. Given the physical nature of the practice of physical therapy, we believed that using the exhaustion portion of the inventory might confound results. As there is a strong correlation between empathy and the other two measures of burnout, namely depersonalization and personal accomplishment (Wilkinson et al., 2017; Yuguero et al., 2017), we chose to solely use the work disengagement subscore of the OLBI that consists of 8 items scored on a 4-point Likert-type scale. There are 4 positively and 4 negatively worded items with the latter being scored inversely, thus a higher score represents higher disengagement (Demerouti, Bakker, Vardakou, & Kantas, 2003). The internal consistency (Cronbach’s α) for the OLBI disengagement subscale has been reported between .79 and .84 (Demerouti et al., 2003; Demerouti et al., 2010) and test-–retest correlation found to be r = .34 after 4 months, which is consistent with findings from other burnout measures (Halbesleben & Demerouti, 2005).
The demographic survey provided information regarding participant’s total years of practice, age, practice setting, and gender. To maintain anonymity of participants, we used prespecified ranges to collect data on years of practice and age.
Procedures
Prospective participants were contacted via e-mail on the first of each month during the data collection period (June through December 2017) explaining purpose of the study, maximal expected time commitment, voluntary nature of participation, and dates of data collection, which coincided with department meetings or educational sessions. Each participant was asked to complete the three forms and was instructed not to identify themselves in any way. The procedure was repeated with a goal of obtaining 120 respondents.
Data Analysis
Paper responses were hand-coded and checked by two researchers to assure the demographic survey; the OLBI and the JSE-HP could be linked for analysis while preserving anonymity. An adequate response to the survey was defined as having 16 or more of the 20 JSE-HPS questions answered (M. Hojat et al., 2002) and fully completed OLBI. All completed questionnaires met the criteria for adequate response and therefore were included in analysis. In cases where JSE-HP surveys were incomplete but had 16 or more responses, missing data were entered based on guidelines of the scale: Missing items were replaced with the value of the mean score calculated from the items completed by that respondent (M. Hojat et al., 2002). All participants completed the work engagement portion of the OLBI in its entirety, negating the need for replacement of missing items.
The distribution of participants’ overall JSE-HP and OLBI was assessed and summarized. Subsequently, proportions for categorical data on participants’ characteristics along with JSE-HP and OLBI means (SD) scores for each category were calculated.
The internal consistency for the instruments was assessed using Cronbach’s α coefficients for both scales. To explore individual strength and direction of relations between the collected variables, we conducted a series of Spearman and Pearson correlations for categorical and continuous outcomes, respectively.
To examine association between the observed variables, a series of multiple regression analyses was performed with focus on the significant predictors for empathy and disengagement, respectively. The efficacies of developed models were assessed with regard to the adjusted coefficient of determination (R 2).
The final models predicting OLBI and JSE-HP served as the basis in the development of standardized pathways between observed variables, identifying direct and indirect factors impacting empathy among practicing physical therapists. The a priori level of significance was set at α = .05.
Study data were collected and managed using Research Electronic Data Capture (REDCap; Harris et al., 2009). REDCap is a secure, web-based application designed to support data capture for research studies. SPSS Version 24 was used for the generation of descriptive and inferential statistics (IBM Corp. Modified 2016. IBM SPSS Statistics for Windows, Version 24.0, Armonk, NY).
Results
Demographics
Demographic information for the 123 subjects is provided in Table 1. Forty-eight therapists worked at an acute care hospital (39%), 54 in an outpatient physical therapy (PT) setting (44%), and 21 at an acute rehabilitation hospital (17%). Of the total sample twenty-two participants (18%) were male, which is consistent with the higher prevalence of women (70%) in PT practice nationally (American Physical Therapy Association, 2014), and age were grouped into four prespecified categories. Although not identical, the distribution of participants among the four categories for age and years of practice was closely aligned. Consequently, only age was used in further analyses.

Instrument Reliability
The instruments’ internal consistency was examined by calculating Cronbach’s α coefficients for both scales. The OLBI demonstrated reasonable internal consistency with a standardized Cronbach’s α-coefficient = .78. Deletion of any single item did not result in a practically significant improvement. Similarly, the JSE-HP demonstrated reasonable internal consistency with a standardized Cronbach’s α-coefficient = .76. Deletion of any single item did not result in a practically significant improvement.
Study participants had an average score of 15.63 (3.5) for disengagement and 118.5 (9.1) for empathy. Detailed percent breakdowns of the study sample by demographic variables along with summary statistics for disengagement and empathy are provided in Table 1.
Individual Correlations
A series of pairwise correlations between independent and dependent variables is presented in Table 2. The Spearman rank correlation between age and years of practice was very strong, rs = .90 (p < .001); however, this was to be expected based on the nature of the variables.

aStatistically significant at p < .05; +Pearson correlation.
Significant correlations were found between age and work disengagement and years of practice and work disengagement, Spearman rank correlations rs = .19 (p = .03) and rs = .20 (p = .03), respectively (Table 2). A significant correlation was found between gender and empathy, with Spearman rank correlation rs = –.20 (p = .02) indicating females reported higher empathy.
There was no observed correlation between age and empathy or years of practice and empathy (Table 2). There were also no statistically significant relationships observed between work disengagement and practice settings nor gender.
Pearson’s correlation showed work disengagement was negatively correlated with empathy with r = −.32 and a 90% confidence interval [−.446, −.178], suggesting an inverse relationship between work disengagement and empathy.
Multiple Regression Analysis
To examine statistically predictive relationships between the observed variables, a series of multiple regressions was performed. Since gender and age were significant predictors for empathy and disengagement, respectively, these were the focus of the models. Although neither empathy nor work disengagement was correlated with practice setting, the variable of practice setting remained in the analysis, as it was directly related to one of our hypotheses. Other measured variables were assessed, but that inclusion did not result in statistically significant models offering a better fit, therefore have not been reported here.
Specifically, Model 1 predicts disengagement based on three age categories (21–26, 27–31, ≥37), and Model 2 predicts disengagement based on the three age categories, gender (male), and practice setting. Model 1 explained 4.3% (adjusted R 2) of variance in disengagement scores and was used in the subsequent pathway analysis (Table 3). Similarly, Models 3 and 4 predict empathy according to study variables including disengagement. Model 3, the final model after variable selection, included gender (male) and work disengagement, explaining 12.9% (adjusted R 2) of variance in empathy scores in the study population (Table 3).

Note: To prevent multicollinearity, age was selected for analysis rather than years of practice due to the very strong correlation, and in this sample, the age variable had no missing data.
Path Analysis
The standardized results from Models 1 and 3 (the most parsimonious statistically predictive models) were combined into a path model examining the direct and indirect effects of gender (male), three age categories (21–26, 27–31, ≥37), and work disengagement (OLBI) on the primary dependent variable, empathy (JSE-HP). The estimated direct effects from age categories to disengagement are β* = .23 for 27–31, β* = .32 for 32–36, and β* = .30 for age ≥37. The estimated direct effects from gender (male) to empathy (β* = −.21) and from disengagement to empathy (β* = −.30). The estimated indirect effects from age categories to empathy are β* = −.07 for 27–31, β* = −.10 for 32–36, and β* = −.09 for age ≥37.
Discussion
This is the first study, to our knowledge, that quantitatively measured empathy in practicing physical therapists with varying years of clinical practice. This is also the first study to explore a possible relationship between clinical empathy in physical therapists and practice setting. Finally, this study investigated the relationship between self-reported empathy and work disengagement in practicing physical therapists.
The mean self-reported clinical empathy level in this cohort of 123 physical therapists with a variety of years of practice was 118.5 (9.1). We found only one study that potentially measured clinical empathy in practicing physical therapists (Bayliss & Strunk, 2015). The purpose of that study by Bayliss and Strunk (2015) was to measure empathy levels of physical therapy students as they progressed through their professional doctor of physical therapy (DPT) education, and subsequently, a mean empathy score of 119.21 (12.53) was reported for a cohort of 29 former students who were surveyed 6 months after graduation. If those graduates were employed at 6 months postgraduation, then it can be assumed these would be empathy levels of novice practicing physical therapists.
Since there are currently no cutoff scores to indicate high or low empathy levels on the JSE-HP, the authors are left to compare this study’s findings with published results from other practicing health-care professionals. In the nursing profession, there are numerous reports that measure nursing empathy that range from an JSE-HP score of 92.88 to 118.0 (Bourgault et al., 2015; Fields et al., 2004; Gosselin et al., 2016; Kliszcz, Nowicka-Sauer, Trzeciak, Nowak, & Sadowska, 2006; Kuo, Cheng, Chen, Livneh, & Tsai, 2012). Clinical empathy measured in mental health therapists in the UK was reported to have a mean score of 121.2 (9.53; Brockhouse, Msetfi, Cohen, & Joseph, 2011), while pharmacists in Japan scored 108.9 (12.5; Higuchi et al., 2015). A recent study of general practicing physicians in Denmark reported a mean empathy score of 117.9 (10.1; Charles, Ahnfeldt-Mollerup, Søndergaard, & Kristensen, 2018). In a study by M. Hojat et al. (2002), clinical empathy levels stratified physicians into three groups according to practice specialties: patient-oriented specialties, technology-oriented specialties, and a middle group. Physicians who practiced in people-oriented specialty groups, which included such disciplines as psychiatry and pediatrics, reported high levels of clinical empathy (120.5–127.0), while those who practiced in more technology-oriented areas of medicine such as anesthesiology and radiology had the lowest empathy scores (116–118; M. Hojat et al., 2002). Chaitoff et al. (2017) found similar results in their study on physician specialty practice and empathy levels.
Since the practice of physical therapy requires a significant amount of face-to-face time, we believed that physical therapists would demonstrate levels of clinical empathy similar to those levels reported by other health-care professions who spend substantial time in direct patient care. The self-reported empathy levels of the physical therapists in our sample (118.5) were lower than the top tier of physicians as stratified by empathy scores and were more similar to the middle group, which included physicians practicing in general surgery and obstetrics and gynecology in the study by M. Hojat et al. (2002) and emergency room physicians in the study by Chaitoff et al. (2017). It would seem that clinical empathy in physical therapists was higher than those reported in the nursing and pharmacy professions as well as some physician groups but not as high as mental health therapists and some other physician specialties.
In a number of studies, levels of clinical empathy have been correlated to practice setting. Chaitoff et al. (2017) used practice environment as a variable in their study, finding that physicians who practice in an outpatient setting had higher levels of clinical empathy than physicians who work in an inpatient setting. Nurses surveyed in a Canadian emergency room showed a mean JSE-HP score of 92.88 (6.99; Bourgault et al., 2015), while nurses who worked in a Canadian intensive care unit had a mean score of 118.0 (Gosselin et al., 2016). Clinical empathy measured in nurses working in a hospital in Taiwan measured a mean of 110.66 (Kuo et al., 2012), while nurses in a U.S. hospital had a mean of 117.2 (Fields et al., 2004). These studies on clinical empathy levels in nursing show differences that may be related to nursing setting; however, as these studies were done independently from one another, the ability to definitively correlate nursing empathy with practice setting is limited. In this study, contrary to our assumptions, the mean self-reported levels of empathy for PTs practicing in the three different settings were not significantly different. This may be due to strong patient–physical therapist relationships that develop regardless of the practice setting. In the studies by Hojat et al. (2002) and Chaitoff et al. (2017), physician specialty practice rather than practice setting yielded different physician empathy levels. Perhaps practicing physical therapists who hold physical therapy board specializations (such as neurological, geriatric, orthopedic, etc) as conferred by the American Board of Physical Therapy Specialists would have produced a different outcome than using the physical therapy practice setting.
Occupational burnout is defined as a sense of being overextended by the workplace demands (high emotional exhaustion), a feeling of being detached or cynical toward the person receiving health care (high depersonalization), compounded by feeling ineffective while fulfilling the requirements of patient care (low personal achievement; Maslach & Jackson, 1981; Maslach & Leiter, 2016; Vercambre, Brosselin, Gilbert, Nerrière, & Kovess-Masféty, 2009). While workplace burnout is a complex abstract construct that is multifactorial and difficult to measure, the relationship between clinical empathy and burnout has been reported in a variety of health-care disciplines. A systematic review by Wilkinson et al. (2017) supported an inverse relationship between empathy and burnout in both physicians and in nurses. A number of studies suggest that this inverse correlation may be due to the creation of meaningful relationships between the health-care professional and the patient, allowing the care provider to develop professional satisfaction, which may, in turn, help prevent workplace burnout (Halpern, 2003; Roter, 1997; Thirioux, Birault, & Jaafari, 2016). Our results confirm that in practicing physical therapists, empathy levels and work disengagement were negatively associated with a correlation coefficient of −.32. Although our results specifically focus on work disengagement, this concept and burnout are well established as overlapping experiences (Taris, Ybema, & Beek, 2017). In this study, we found that work disengagement along with gender explained 12.9% of self-reported levels of empathy. While there continues to be a need to further investigate all the determinants that either promote or detract from caregiver empathy, it is clear that workplace disengagement plays an important role.
Other findings
Our data suggest that there is no statistically significant association between practice setting and employee disengagement. Despite the unique challenges facing PTs in different settings, our results suggest that the factors influencing work disengagement may not be setting-specific, though caution must be taken when interpreting these results, given the convenience sampling from one metropolitan region.
Respondents in our sample who were in the 32–36 age range and 8–12 years of experience reported highest levels of work disengagement and the lowest levels of self-reported empathy. Research in the relationship between age and work disengagement has shown inconsistencies. Poulsen et al. (2014) demonstrated the highest degree of workplace burnout was found in occupational therapists with less than 10 years of experience (Poulsen et al., 2014). Similar results were found by Tijdink, Vergouwen, and Smulders (2014) when looking at burnout among medical professors. A study by Donohoe, Nawawi, Wilker, Schindler, and Jette (1993) reported there was no relationship between years of experience and levels of burnout in a population of physical therapists. Ahola, Honkonen, Virtanen, Aromaa, and Lönnqvist (2008) surveyed the Finnish population engaged in all types of employment and noted that burnout rates were greatest in the youngest of the young woman category, the oldest of the aging women category, and for men, the highest level of burnout was found in the middle age-group. Finally, in a meta-analysis by Brewer and Shapard (2004), a negative correlation was noted between age and burnout as well as negative correlation between years in a job and burnout. Hypotheses for possible explanation of these results are as varied as the results themselves. As we did not include any of the usual proposed precursors to burnout in our demographic survey, such as marital status, home-living children, or salary, it is not possible to determine reasons for our findings. Future studies to investigate the individual or organizational antecedents of work disengagement are warranted.
Finally, female PTs in our sample had higher levels of self-reported empathy than male PTs. This finding is consistent with a number of other studies measuring clinical empathy in health-care professionals (Bayliss & Strunk, 2015; Chaitoff et al., 2017; M. Hojat et al., 2011; M. Hojat et al., 2001).
Limitations
This study is subject to several limitations including limited sample size and lack of separate temporal measurements. Because of our cross-sectional design, causality between work disengagement and empathy cannot be explained by the data. These findings are also self-reported and as such are subject to response bias or perceptions of social desirability. The convenience sample used for this study was limited to one geographic region (Massachusetts and Rhode Island) and may not be reflective of demands in different parts of the country. Factors such as salary, reimbursement rate, administrative burden, and other work-related factors will vary from state to state and therefore may produce different results. The practice settings represented did not include providers in the home health, school, or long-term care settings, further limiting the generalizability of these findings. Furthermore, the outpatient sites surveyed were a university-based and a hospital-based system, not a private practice clinic. Interpreting the influence of practice setting on empathy and disengagement may be different as these nonrepresented settings may have different demands and stressors than the settings represented here.
Future Studies
We employed a validated and widely used tool, the JSE-HP, to measure self-reported empathy. Our data can therefore be used as a starting point for future studies to develop norms and cutoff scores using a larger, more representative sample of practicing PTs.
Given that only 12.9% of the variance of empathy was accounted for, there are additional latent factors that contribute to individuals’ levels of empathy, which were not identified or addressed in this study. Evidence has shown that a therapeutic patient–therapist relationship, of which empathy is a part, has a positive effect on patient satisfaction and reported outcomes (Hall et al., 2010; Kidd et al., 2011; Peiris et al., 2012). Therefore, future quantitative research to examine the potential impact of measured levels of empathy on the outcomes of patients receiving physical therapy is indicated.
Work engagement has been associated with better patient outcomes in health disciplines other than physical therapy. It is therefore important for rehabilitation organizations to gauge the level of workplace engagement among physical therapists, as it could have a positive organizational consequence such as retention of therapists, increased work satisfaction, and better patient outcomes. Future studies could explore additional factors related to personal characteristics and work environments that could influence work engagement and empathy. Additionally, these results suggest there may be specific subpopulations who may benefit from supportive interventions to improve engagement and thereby improve empathy.
Conclusions
Physical therapists demonstrated a mean empathy level of 118.5, which is higher than reported levels of clinician empathy in the nursing and pharmacy professionals, but not as high as some physician subgroups or mental health therapists. Empathy levels in practicing physical therapists did not differ from one type of health-care setting to another. Caregiver empathy and work disengagement were negatively correlated in our sample of practicing physical therapists. By utilizing a path analysis, we were able to gain insight into the complex matrix between predictors and the dependent variable of empathy.
