Psychometric validation and cross-cultural adaptation of the Integrated Palliative care Outcome Scale in Polish (IPOS-Pol)

Objective The study aimed to assess the reliability and validity of the IPOS-Pol for patient self-reporting. Method Patients (>18 years of age) with advanced cancer admitted to three palliative care centers (inpatient units and home-based) were recruited to a multicenter, cross-sectional, observational, prospective study. Participants provided responses to the IPOS-Pol Patient version and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – Core 15 – Palliative Care (EORTC QLQ-C15-PAL) Polish version at baseline (T1) and four to seven days later (T2). We assessed test–retest reliability, internal consistency, and construct validity of the tool. Results One hundred and eighty patients were included. Test–retest reliability demonstrated no statistically significant differences in the average outcomes of the IPOS-Pol between T1 and T2 (27.2 ± 9.2 vs. 26.5 ± 8.7; p > 0.05). The intra-class correlation coefficient between T1 and T2 was r = 0.83 (p < 0.0001), the intra-class correlation coefficient for test–retest reliability of the IPOS-Pol items ranged from 0.63 to 0.84 (p < 0.0001), and the Cronbach's α coefficient for internal consistency was 0.773. The correlation coefficient between the IPOS-Pol and EORTC QLQ-C15-PAL total score was 0.79 (p < 0.001). Significance of results The patient version of the Polish adaptation of IPOS is a valid and reliable outcome measure for assessing symptoms and concerns of individuals receiving palliative care, as well as the quality of care provided.

The Being Taken Seriously Questionnaire—Development and Psychometric Evaluation of a PREM Measure for Person-Centeredness in a High-Tech Hospital Environment

There is a need for patient-reported experience measures (PREMs) in high-tech hospital environments based on the philosophy of person-centeredness. The aim of this study was to describe the development and initial psychometric evaluation of a measure of person-centeredness by means of being taking seriously. In this cross-sectional survey, the study sample (n = 79) completed two measures, the Being Taken Seriously Questionnaire—Patient version (BTSQ-P) which was the measure undergoing psychometric evaluation, and the Person-Centered Climate Questionnaire—Patient version (PCQ-P) that was used to evaluate the climate in which the intervention was occurring. The expected scale dimensionality was examined both by the confirmatory multi-trait analysis program and by explorative principal component analysis (with oblique, varimax rotation). Scale reliability was estimated using ordinal alpha and Cronbach’s alpha. One solid factor was generated. This factor had good internal convergent validity and good item–scale reliability, covering 80.41% of the variance. The interitem correlation ranged from 0.759 to 0.908 and the alpha was 0.93 (ordinal alpha) and 0.87 (Cronbach’s alpha) respectively. There was a strong relationship between BTSQ-P and the PCQ-P dimension safety climate. In conclusion, the internal consistency, reliability and concurrent validity of the BTSQ-P was satisfactory for use in a high-tech hospital environment.
