ABSTRACT

The main aim of this study was to make a Spanish adaption of the international Patient-Doctor Relationship Questionnaire (PDRQ) that assesses the quality of patient-doctor relationship in Spanish patients admitted to an Internal Medicine Service under conditions of regular clinical practice.
A total of 188 adult patients of 6 Internal Medicine physicians from a University Hospital in downtown Madrid were analyzed. Sociodemographic and clinical variables were collected and the PDRQ Spanish version questionnaire was administered.
Results showed excellent psychometric data on reliability, factorial, and construct validity. Furthermore, based on scientific literature, criteria validity was determined, considering continuity of care as external criteria. Results ratify previous data related to positive relation between quality of doctor-patient relation and continuity of care.
The Spanish 13 item version of the PDRQ (CREM-P in Spanish) proved to be a valid instrument for assessing the quality of patient-doctor relation in adult patients, with clinical and research value.

    • "The corrected item-total correlation was ≥0.87 (Table 2) which was highly significant and aligns with others as it was ≥0.94 in PDRQ-9 German validation study[1]. Factor analysis of PDRQ-9 Bangla was revealed as a single factor scale and the solution could not be rotated in the varimax rotation (Table 3) as PDRQ-9 German was unidimensional scale and PDRQ-9 Dutch, PDRQ Spanish were validated as single factor scale after removal of second factor with the help of the factor analysis without significant alteration of scale property, reliability, and validity ultimately[1,4,5].

    ABSTRACT: . The patient-doctor relationship is an important issue in health care as it is linked to patient satisfaction, treatment adherence, and treatment outcome. The PDRQ-9 is brief instrument which has an excellent overall internal consistency to measure it. Objective . It was aimed at developing a culturally adapted and validated Bangla version of Patient-Doctor Relationship Questionnaire (PDRQ-9). Method . Data were collected during the period of May 2015 to July 2015 from 50 patients by interviewing with the final Bangla version of PDRQ-9 obtained by ideal translation-back translation procedure with nonprobability purposive consecutive sampling and analyzed by Statistical Package of Social Science (SPSS) 16.0 and Microsoft Excel 2007 version software. Result . The internal consistency of Bangla PDRQ-9 was measured by Cronbach’s α which was 0.97. Only one factor was extracted from varimax rotation factor analysis with high commonalities between the items. Conclusion . Bangla version of PDRQ-9 is valid, accepted, and widely applicable in clinical practice, research, public health, and primary health care in Bangladesh.

    • "Data quality: Similar to the Dutch [8] and Spanish studies [10], [11], ceiling effects were detected in the German PDRQ-9. The ability of the PDRQ-9 to discriminate within the upper region of satisfaction with PDR is insufficient [8], [11]. "

    ABSTRACT: The patient-doctor relationship (PDR) as perceived by the patient is an important concept in primary care and psychotherapy. The PDR Questionnaire (PDRQ-9) provides a brief measure of the therapeutic aspects of the PDR in primary care. We assessed the internal and external validity of the German version of the PDRQ-9 in a representative cross-sectional German population survey that included 2,275 persons aged≥14 years who reported consulting with a primary care physician (PCP). The acceptance of the German version of this questionnaire was good. Confirmatory factor analysis demonstrated that the PRDQ-9 was unidimensional. The internal reliability (Cronbach's α) of the total score was .95. The corrected item-total correlations were≥.94. The mean satisfaction index of persons with a probable depressive disorder was lower than that of persons without a probable depressive disorder, indicating good discriminative concurrent criterion validity. The correlation coefficient between satisfaction with PDR and satisfaction with pain therapy was r = .51 in 489 persons who reported chronic pain, indicating good convergent validity. Despite the limitation of low variance in the PDRQ-9 total scores, the results indicate that the German version of the PDRQ-9 is a brief questionnaire with good psychometric properties to assess German patients' perceived therapeutic alliance with PCPs in public health research.

    ABSTRACT: Objective: The main aim of the study was to examine the impact of patients' ethnic diversity on the patient satisfaction level to psychiatry care and explores the satisfaction domains with mental health care. Design: This is a prospective cross sectional study. Setting: Psychiatry department of the Hamad Medical Corporation. Subjects: The study sample was Qatari and other Arab nationals aged 18 to 65 years who visited the psychiatry department during the study period; April 2009 to August 2009. A total of 1300 adult patients were approached and 1054 (81.1%) expressed their consent to participate in this study. Method: A standard forward-backward procedure was applied to translate the English version of the PDRQ to Arabic. PDRQ was administered by pre-trained nurses among the psychiatry patients. The main outcome measures of the study were 13-item patient doctor relationship questionnaire (PDRQ) score and other 11 items assessing what patients need from psychiatrists. Also, Socio-demographic data of the patients was collected. Results: Of the studied patients, there were 479 Qataris (45.4%) and 575 other Arabs (54.6%). There was a significant differences found between Qatari and Arab expatriate patients in marital status (p=0.036), level of education (p<0.001), occupation (p<0.001), household income (p<0.001), number of rooms in the house (p<0.001) and people living in the house (p<0.001). Arab expatriate patients (480;55.9%) were more satisfied with psychiatry care than Qatari patients (378;44.1%) especially in the age group (18-34) years of both the ethnic groups (164;43.4% vs 214;44.6%). Overall patient satisfaction level was significantly higher in literate Arab patients with secondary and university degree (333;69.3%), while it was lower in Qataris (185;49%). Satisfaction score was almost the same between Qatari and Arab expatriate patients with no significant difference. But satisfaction score was significantly higher in Spanish population in all domains of satisfaction compared to our study sample (p<0.0001). Conclusions: The study findings revealed that there is no ethnic difference observed in the satisfaction score between Qatari and Arab expatriate patients in Qatar, but a significant difference was observed between Arab and Spanish psychiatry patients in all domains of satisfaction.
