Validity and Reliability of the Turkish Version of Needs Based Biopsychosocial Distress Instrument for Cancer Patients (CANDI)

Patient-reported outcome measure to implement routine assessment of cancer survivors' unmet needs: An overview of reviews and COSMIN analysis

As the number of cancer survivors (CSs) is increasing worldwide, providing services relevant to the specific, unmet needs of these individuals is crucial. There are currently various patient-reported outcome measures (PROMs) whose aim is to identify the unmet needs of CSs. Still, limited guidance supports healthcare providers in choosing the most valid and reliable PROMs for this purpose. We conducted this overview of systematic reviews (SRs) on the psychometric properties of PROMs addressing the unmet needs of adult CSs suffering from non-cutaneous cancers. We searched databases for SRs published between 2012 and January 2023. Two SRs were included, covering 14 PROMs tested on 19,151 CSs. These were assessed according to the COSMIN methodology for SRs of PROMs for the quality of their measurement properties and risk of bias, thus providing guidance in selecting PROMs that appropriately reflect the unmet needs of CSs.

Validity and reliability of the Turkish version of the functional assessment of cancer therapy-bone marrow transplant (FACT-BMT) quality of life questionnaire in patients undergoing bone marrow transplantation

OBJECTIVE

The Functional Assessment of Cancer Therapy-Bone Marrow Transplant Version 4 (FACT-BMT) is a widely used instrument to assess quality of life in individuals treated with bone marrow transplantation (BMT). Our aim was to determine the reliability and validity of the Turkish version of the FACT-BMT in patients undergoing BMT.

METHOD

Patients between the age of 20 and 65 years and who had undergone BMT at least 3 months before the study were included. Validity was determined using exploratory and confirmatory factor analysis. To determine convergent validity, the European Cancer Research and Treatment Organization Quality of Life Questionnaire-Cancer30 (EORTC QLQ-C30), the Brief Fatigue Inventory (BFI), and the Eastern Cooperative Oncology Group (ECOG) performance score were used. Cronbach's alpha, intra-class correlation coefficient (ICC), and item-total correlation (ITC) values were calculated to assess the reliability of the FACT-BMT.

RESULTS

Totally, 114 patients (F/M: 47/67) treated with BMT (mean age: 49.50 ± 12.50 years) were included. Confirmatory and exploratory factor analysis revealed that the FACT-BMT and the Bone Marrow Transplantation Subscale (BMTS) had sufficient fit. The FACT-BMT was moderately to strongly correlated with the EORTC QLQ-C30, the BFI, and the ECOG performance score (p < 0.001). Cronbach's alpha and ICC values of the FACT-BMT were acceptable (0.925 and 0.956, respectively). The ITC values of each item of the FACT-BMT were also acceptable (ranged from 0.296 to 0.737). Patients undergoing autologous BMT had a significantly higher BMTS score than those undergoing allogeneic BMT (p < 0.05).

SIGNIFICANCE OF RESULTS

The Turkish version of the FACT-BMT is valid, reliable, and sensitive to changes in quality of life in patients undergoing BMT.

Evaluation of psychometric properties of needs assessment tools in cancer patients: A systematic literature review

Background

Although a wide range of needs assessment tools for cancer patients have been developed, no standardized and commonly accepted instruments were recommended to use in clinical care. This systematic review was conducted to assess the quality of psychometric properties of needs assessment tools among cancer patients in order to help oncology healthcare professionals select the most appropriate needs assessment tools in routine clinical practice.

Methods

Searches were conducted in the electronic databases of PUBMED from 1966, CINAHL from 1960, EMBASE from 1980 and PsychINFO from 1967 as well as additional sources. The quality of psychometric properties of the recruited needs assessment tools was evaluated using the agreed quality criteria for measurement properties of health status questionnaires.

Results

Thirty-seven studies which evaluated the psychometric properties of 20 needs assessment tools were identified. Internal consistency was tested in 32 studies with 9 studies indicating negative rating and 4 studies intermediate rating. Less than half of the studies (13 studies) assessed test-retest reliability, and only 4 studies reported positive rating. Content validity was the most tested psychometric property appraised in 33 studies and indicated positive rating in all the evaluated studies. Structural validity was adequately evaluated in 28 studies with 23 studies reporting intermediate rating. More than half of the studies (29 studies) tested hypothesis testing and 13 studies were rated positive. Cross-cultural validity results were obtained in 13 studies with 7 studies showing negative rating. No data was available on measurement error and criterion validity. Only one study appraised responsiveness and showed intermediate rating. The Supportive Care Needs Survey-Short Form (SCNS-SF) is the most widely used instrument for needs assessment in cancer patients. It had strong evidence for internal consistency, content validity, structural validity and hypothesis testing, and moderate evidence for reliability and cross-cultural validity. Cancer Survivors’ Unmet Needs Measure (CaSUN) reported strong or moderate evidence for internal consistency, reliability, content and structural validity, and hypothesis testing. Furthermore, Supportive Cancer Care Needs Assessment Tool for Indigenous People (SCNAT-IP) had strong evidence for content validity, and moderate evidence for internal consistency, structural validity and hypothesis testing.

Conclusions

Despite several needs assessment tools exist to assess care needs in cancer patients, further improvement of already existing and promising instruments is recommended.
