How many patients are required to provide a high level of reliability in the Japanese version of the CARE Measure? A secondary analysis

Development of the Italian version of the Consultation and Relational Empathy (CARE) measure: translation, internal reliability, and construct validity in patients undergoing rehabilitation after total hip and knee arthroplasty

PURPOSE

To translate and cross-culturally adapt the Consultation and Relational Empathy (CARE) measure into Italian, examine its internal reliability, and construct validity in a rehabilitation setting.

MATERIALS AND METHODS

The translation process consisted of two forward translations, a pre-final version, a back-translation, and a final version, in accordance with available guidelines. We administered the Italian version of the CARE measure to 101 patients hospitalised for rehabilitation after total hip or total knee arthroplasty (THA and TKA). We assessed face validity, internal reliability, and construct validity.

RESULTS

Face validity was high. Patients answered all questions and the "does not apply" option was never selected. Internal reliability (Cronbach's α = 0.962) resulted in line with the original version. The exploratory factor analysis confirmed the unidimensional structure of the CARE measure with 74.82% of variance explained by the first factor.

CONCLUSIONS

The Italian version of the CARE measure showed high face validity. Internal reliability and construct validity were in line with the original version in patients undergoing rehabilitation after THA and TKA.IMPLICATIONS FOR REHABILITATIONInternal reliability and construct validity of the Italian version of the CARE measure are in line with those of the original version of the CARE measure.The Italian CARE measure can be used to assess patient's perceived therapist's empathy in patients undergoing physical therapy after THA and TKA.Physiotherapists should use the CARE measure with more caution in other rehabilitative contexts.

A 2-item version of the Japanese Consultation and Relational Empathy measure: a pilot study using secondary analysis of a cross-sectional survey in primary care

BACKGROUND

The Consultation and Relational Empathy (CARE) measure is a patient-reported measure of physician empathy which is widely used internationally. The Japanese version of the CARE measure has very high internal reliability, suggesting that a shorter version may have adequate validity and reliability.

OBJECTIVE

To investigate a valid shorter version of the Japanese CARE measure.

METHODS

We conducted a pilot study using secondary analysis of previous data obtained from 9 general practitioners and 252 patients and used to develop the Japanese CARE measure. All 1,023 possible combinations of the Japanese CARE items (n = 1-10) were candidates for the short measure. The internal consistency (Cronbach's alpha) and the correlations between candidate short questionnaires and the original questionnaire were calculated. After selecting the most valid short questionnaire, inter-rater reliability was determined using generalizability theory, and construct validity (Spearman's rho) was determined using patient satisfaction.

RESULTS

Two items were selected for a pilot shorter version: item 6 "Showing care and compassion" and item 9 "Helping you to take control." These showed high internal consistency and correlations with the 10-item measure (Cronbach's alpha = 0.920, correlation = 0.979). Forty-five questionnaires per doctor allowed us to reliably differentiate between practitioners. The construct validity for the pilot short measure was high (Spearman's rho 0.706, P < 0.001).

CONCLUSION

We generated a pilot 2-item version of the Japanese CARE measure. This pilot 2-item version provides a basis for future validation studies of short CARE measures in other languages.

Effect of physician attire on patient perceptions of empathy in Japan: a quasi-randomized controlled trial in primary care

Background

There is limited quantitative research on the effect of physician attire on patient–physician relationships. This study aimed to measure the influence of Japanese family physicians’ attire on the “human” aspects of medical care in terms of patient-perceived relational empathy.

Methods

This was a multicenter, prospective, controlled trial conducted in primary clinics in Japan. We explored the effects of family physician attire (white coat vs. casual attire) on patient-perceived empathy. Family physicians were allocated to alternate weeks of wearing a white coat or casual attire during consultations. Patients’ perceptions of physician empathy were evaluated using the self-rated Japanese Consultation and Relational Empathy (CARE) Measure. We used a linear mixed model to analyze the CARE Measure scores, adjusting for cluster effects of patients nested within doctor, age, and sex of patients, and doctors’ sex and years of clinical experience. We used the same method with Bonferroni adjustment to analyze patient sex differences in perceived empathy.

Results

A total of 632 patients of seven family physicians were allocated to white coat-wearing consultations (n = 328), and casual attire-wearing consultations (n = 304). There was no difference in CARE Measure scores between white coat and casual primary care consultations overall (p = 0.162). Subgroup analysis of patient sex showed that CARE Measure scores of male patients were significantly higher in the Casual group than in the White coat group (adjusted p-value = 0.044). There was no difference in female patient scores between White coat and Casual groups (adjusted p-value = 1.000).

Conclusions

This study demonstrated that physician attire (white coat or casual attire) in a primary care setting did not affect patient-perceived relational empathy overall. However, male patients of physicians wearing casual attire reported higher physician empathy. Although empathy cannot be reduced to simple variables such as attire, white coats may have a negative effect on patients, depending on the context. Family physicians should choose their attire carefully.

Assessing the empathy of medical students during medical interview training in Japan by using mixed-methods surveys of simulated patients

This article was migrated. The article was marked as recommended. Background: Medical interviews are performed during objective structured clinical examinations, to assess the communication skills of medical students. In particular, medical students are assessed regarding whether they demonstrate empathy during these staged interviews. However, no studies to date have analyzed the validity of the methods to evaluate empathy during objective structured clinical examinations. Aim: Here we sought to identify factors affecting whether simulated (standardized) patients (SPs) felt that the medical students had treated them empathetically during medical interview training. Methods: The training involved the participation of SPs during the bedside learning of fifth-year medical students in Japan. After the students completed medical interview training, we conducted a questionnaire-based survey. We developed the list of questionnaire items through semi-structured interviews asking SPs to describe when the student had been empathetic. Results: The item "I felt that the student was empathic throughout the interview" was significantly correlated with "I was given enough time to talk at the beginning of the interview," "The student made good eye contact," "The student's attitude was appropriate," "I was able to say enough of what I wanted to talk about," and "The student used phrases that expressed empathy." Multiple regression analysis revealed that "The student used phrases that expressed empathy" was the only independent predictor of "I felt that the student was empathic throughout the interview." Conclusions: The factor that correlated most strongly with the SP feeling that the student was empathic during a medical interview was "The student used phrases that expressed empathy." However, correlations also occurred with open-ended questions and the student's level of attention at the beginning of the interview and with the student's attitude. Together, these findings indicate that several types of both verbal and nonverbal communication determined whether SPs felt that medical students showed empathy during staged medical interviews.
