Psychometric properties of the Czech Integrated Palliative Outcome Scale: Reliability and content validity analysis

Abstract Background: Outcome measurement is an essential part of the evaluation of palliative care and the measurements need to be reliable, valid and adapted to the culture in which they are used. The Integrated Palliative Outcome Scale (IPOS) is a widely used tool for assessing personal-level outcomes in palliative care. The aim of this study was to provide Czech version of IPOS and asses its psychometric properties. Methods: Patients receiving palliative care in hospice or hospitals completed the IPOS. The reliability of Czech IPOS was tested with Cronbach alpha (for internal consistency), the intraclass correlation coefficient for total IPOS score and weighted Kappa (for test-retest reliability of individual items). Factor analysis was used for elucidating the construct (Exploratory Factor Analysis). Convergent validity was tested with correlation analysis (Spearman correlation) in a part of the sample, who completed also the Edmonton Symptom Assessment System (ESAS) and the Palliative Performance Scale (PPS). Results: The sample consisted of 140 patients (mean age 72; 90 women; 81 % oncological disease). The Cronbach alpha was 0.789; intraclass correlation was 0.88. The correlations of IPOS with ESAS was R= 0.4 and PPS R= -0.2. Exploratory factor analysis revealed a 2-factor solution on our data. The first factor covers emotional and information needs and the second factor covers physical symptoms. Conclusion: Czech IPOS has very good reliability regarding both internal consistency and test-retest reliability. Together with an item analysis results, we can conclude that the Czech adaptation of the tool was successful. The convergent validity needs to be assessed on the larger sample and the proposed 2-factor internal structure of the questionnaire has to be confirmed by using CFA.

Introduction: There is a need to have appropriate information about the ability of Parkinson's disease (PD) patients to perform cognitive instrumental activities of daily living (IADL). The purpose of the present study was to assess the psychometric properties of the Persian version of the Penn Parkinson's Daily Activities Questionnaire-15 (PDAQ-15). Methods: A total of 165 knowledgeable informants of PD patients completed the PDAQ-15. The Clinical Dementia Rating Scale, Hoehn and Yahr staging, Hospital Anxiety and Depression Scale (HADS) and Lawton IADL scale were included in the study. Internal consistency and test-retest reliability were evaluated by Cronbach's alpha coefficient and intraclass correlation coefficient (ICC), respectively. To examine the dimensionality of the questionnaire, exploratory factor analysis was used. The construct validity was assessed using Spearman rank correlation test. To assess the discriminative validity, PDAQ-15 scores were compared across cognitive stages. Results: The PDAQ-15 showed strong internal consistency (Cronbach's α = 0.99) and test-retest reliability (ICC= 0.99). Only one dimension identified for the PDAQ-15 in the factor analysis. There was strong correlation between PDAQ-15 with depression domain of HADS scale and Lawton IADL scale. (rs = |0.71–0.95|). The correlation of PDAQ-15 with anxiety domain of HADS scale was moderate (rs = 0.66). Discriminative validity analysis showed that the PDAQ-15 has significant power to discriminate between PD patients across cognitive stages. Conclusion: These results suggest that the PDAQ-15 is a valid and reliable PD-specific instrument that can be useful in clinical and research settings.

The English version of the Independent Television Commission-Sense of Presence Inventory (ITC-SOPI), which was developed in 2001 to measure how involved or present participants are when experiencing different media, has substantial psychometric evidence. This study was used to translate and validate the ITC-SOPI in interactive virtual environments among the Chinese population. We used the forward-backward translation procedure. An expert panel reviewed the translated ITC-SOPI until the Chinese version of the ITC-SOPI was finalized. A total of 210 participants (133 males and 77 females), with a mean age of 23.05 years ( SD = 3.56, range = 17–47), completed the Chinese ITC-SOPI. The following psychometric properties were examined: factor structure, internal consistency, test–retest reliability, and convergent validity. Confirmatory factor analysis (CFA) showed a good fit (χ2 /df = 1.70, Tucker–Lewis Index [TLI] = 0.91, comparative fit index [CFI] = 0.92, root mean square error of approximation [RMSEA] = 0.058) of the four-factor model (spatial presence, engagement, ecological validity, and negative effects). For each factor, the Chinese ITC-SOPI had high internal consistency (Cronbach’s α ranging from 0.75 to 0.87) and test–retest reliability (intraclass correlation coefficient ranging from 0.82 to 0.91). Significant correlations were identified between all factors and the Interpersonal Reactivity Index-C (IRI-C) and the Generalized Anxiety Disorder-7 (GAD-7). The Chinese ITC-SOPI had good psychometric properties, suggesting that it is a reliable and valid tool for evaluating media users’ sense of presence in a Chinese-speaking context.

AbstractObjective:Identification of areas that family members consider important and in which they need help and support is one of the main goals of palliative care. Our research aimed to assess the psychometric properties of a Czech version of the Family Inventory of Needs (FIN).Method:The group comprised 272 family members of terminally ill cancer patients at the University Hospital in Ostrava. Reliability was assessed by internal consistency (Cronbach's alpha), test–retest reliability, and correlation of both scales and items within the scales (item–total correlation). To verify construct validity, exploratory factor analysis and principal component analysis with a varimax rotation were utilized.Results:Using exploratory factor analysis, the following four factors (domains) were extracted: basic information, information on treatment and care, support, and comfort of the patient. Cronbach's α for the entire questionnaire was 0.924 on the importance scale and 0.912 for the satisfaction scale; for all domains, a value of α greater than 0.7 was ascertained. Test–retest reliability was also higher than 0.7 for all domains. On the satisfaction scale, a moderate correlation was confirmed between unmet needs in the domains basic information, support, and comfort of the patient, and the total score, and in selected quality-of-life domains.Significance of results:The results of tests on the psychometric properties of the FIN questionnaire demonstrated at least satisfactory validity and reliability, and confirmed that it can be employed to assess the needs of palliative care patients in the Czech Republic.

Abstract Background Critical thinking disposition helps medical students and professionals overcome the effects of personal values and beliefs when exercising clinical judgment. The lack of effective instruments to measure critical thinking disposition in medical students has become an obstacle for training and evaluating students in undergraduate programs in China. The aim of this study was to evaluate the psychometric properties of the CTDA test. Methods A total of 278 students participated in this study and responded to the CTDA test. Cronbach’s α coefficient, internal consistency, test-retest reliability, floor effects and ceiling effects were measured to assess the reliability of the questionnaire. Construct validity of the pre-specified three-domain structure of the CTDA was evaluated by explanatory factor analysis (EFA) and confirmatory factor analysis (CFA). The convergent validity and discriminant validity were also analyzed. Results Cronbach’s alpha coefficient for the entire questionnaire was calculated to be 0.92, all of the domains showed acceptable internal consistency (0.81–0.86), and the test-retest reliability indicated acceptable intra-class correlation coefficients (ICCs) (0.93, p < 0.01). The EFA and the CFA demonstrated that the three-domain model fitted the data adequately. The test showed satisfactory convergent and discriminant validity. Conclusions The CTDA is a reliable and valid questionnaire to evaluate the disposition of medical students towards critical thinking in China and can reasonably be applied in critical thinking programs and medical education research.

Abstract Objectives To examine the validity and reliability of the Mandarin version of the Treatment Burden Questionnaire (TBQ) among stroke patients. Background Stroke patients need long-term management of symptoms and life situation, and treatment burden has recently emerged as a new concept that can influence the health outcomes during the rehabilitation process. Methods The convenience sampling method was used to recruit 187 cases of stroke patients in a tertiary grade hospital in Tianjin for a formal investigation. Item analysis, reliability and validity tests were carried out. The reliability test included internal consistency and test–retest reliability. And as well as content, structure and convergent validity were performed for the validity test. Results Of the 187 completed questionnaires, only 180 (96.3%) were suitable for analysis. According to the experts’ evaluation, the I-CVI of each item was from 0.833 to 1.000, and the S-CVI was 0.967. The exploratory factor analysis yielded three-factor components with a cumulative variation of 53.054%. Convergent validity was demonstrated using measures of Morisky’s Medication Adherence Scale 8 (r = –0.450, P < 0.01). All correlations between items and global scores ranged from 0.403 to 0.638. Internal consistency reliability and test–retest reliability were found to be acceptable, as indicated by a Cronbach’s α of 0.824 and an intraclass correlation coefficient of 0.846, respectively. Conclusions The Mandarin TBQ had acceptable validity and reliability. The use of TBQ in the assessment of treatment burden of stroke survivor may benefit health resources allocation and provide tailor therapeutic interventions to construct minimally disruptive care.

Abstract Objective The aim of this study was to investigate the validity and reliability of the Patient Dignity Inventory (PDI) in the Turkish society, which was developed to evaluate dignity-related distress in palliative care patients. Methods One hundred and twenty-seven adults with advanced cancer hospitalized in several clinics of two university hospitals were included in the study. The patients whose Palliative Performance Scale score was at least 40% were recruited to study. The data were collected with a patient demographic form, the Turkish version of Hospital Anxiety and Depression Scale (HADS-TR), and the Turkish version of the PDI (PDI-TR). The PDI-TR was finalized and back-translated after translating into Turkish and obtaining 10 expert opinions. Exploratory and confirmatory factor analysis, internal consistency, concurrent validity, and test–retest reliability analysis were performed. Results The Cronbach's α coefficient of PDI-TR was 0.94. Factor analysis resulted in a five-factor solution, and all items were loaded on factors. Factors were labeled as symptom distress, existential distress, self-confidence, dependency, and supportive care needs and accounted for 68.70% of the overall variance. The model's normed fit index, comparative fit index, and X2/SD were found between acceptable range (0.90, 0.93, and 2.64, respectively). A positive and strong correlation was found between subdimension scores of HADS-TR and the total score of PDI-TR (r = 0.70 for anxiety subdimension; r = 0.73 for depression subdimension). The test–retest reliability was conducted with 32 patients within the sample two weeks after the first application, and no significant difference was found between the two application scores as the result of paired-sample t-test (p > 0.05). An intraclass correlation coefficient of test–retest reliability was r = 0.855. Significance of results PDI-TR was found to be a valid and reliable tool in palliative care patients in Turkish society.

Background: The Sexual Interest and Desire Inventory Female (SIDI-F) is a clinician-administered scale that allows for a comprehensive assessment of symptoms related to Hypoactive Sexual Desire Dysfunction (HSDD). As self-report questionnaires may facilitate less socially desirable responding and as time and resources are scarce in many clinical and research settings, a self-report version was developed (SIDI-F-SR). Aim: To investigate the agreement between the SIDI-F and a self-report version (SIDI-F-SR) and assess psychometric properties of the SIDI-F-SR. Methods: A total of 170 women (Mage=36.61, SD=10.61, range=20-69) with HSDD provided data on the SIDI-F, administered by a clinical psychologist via telephone, and the SIDI-F-SR, delivered as an Internet-based questionnaire. A subset of 19 women answered the SIDI-F-SR twice over a period of 14 weeks. Outcomes: Intraclass correlation as well as predictors of absolute agreement between SIDI-F and SIDI-F-SR, as well as internal consistency, test-retest reliability, and criterion-related validity of the SIDI-F-SR were examined. Results: There was high agreement between SIDI-F and SIDI-F-SR (ICC=.86). On average, women scored about one point higher in the self-report vs. the clinician-administered scale. Agreement was higher in young women and those with severe symptoms. Internal consistency of the SIDI-F-SR was acceptable (α=.76) and comparable to the SIDI-F (α=.74). When corrections for the restriction of range were applied, internal consistency of the SIDI-F-SR increased to .91. Test-retest-reliability was good (r=.74). Criterion-related validity was low but comparable between SIDI-F and SIDI-F-SR.
