Psychometric properties of the Dutch extended Cancer Survivors' Unmet Needs measure (CaSUN-NL)

A Critical Overview of the Construct of Supportive Care Need in the Cancer Literature: Definitions, Measures, Interventions and Future Directions for Research

The growing amount of evidence about the role of supportive care in enhancing cancer patients' outcomes has made healthcare providers more sensitive to the need for support that they experience during cancer's trajectory. However, the lack of a consensus in the definition of supportive care and lack of uniformity in the theoretical paradigm and measurement tools for unmet needs does not allow for defined guidelines for evidence-based best practices that are universally accepted. Contemporary cancer literature confirms that patients continue to report high levels of unmet supportive care needs and documents the low effectiveness of most of the interventions proposed to date. The aim of this critical review is to consolidate the conceptual understanding of the need for supportive care, providing definitions, areas of expertise and a careful overview of the measurement tools and intervention proposals developed to date. The possible reasons why the currently developed interventions do not seem to be able to meet the needs, and the issues for future research were discussed.

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.

Breast cancer patients' needs and perspectives on a one-on-one peer support program: quantitative and qualitative analyses

PURPOSE

Although peer support programs as a health resource have become increasingly popular, only limited studies evaluated the added value of one-on-one peer support for breast cancer patients. This study aims to bridge the knowledge gap by focusing on two related research topics. First, we evaluated emotional well-being and (unmet) needs regarding supportive care. Second, we evaluated patients' perspectives on their experiences after having one-on-one peer support.

METHODS

A quantitative analysis was conducted to provide insight in patients' symptoms of anxiety and depression (HADS), quality of life (EORTC-QLQ-C30), and supportive care needs (CaSUN-questionnaire). Furthermore, approximately 1 year after the implementation of a one-on-one peer support program, focus groups were conducted to evaluate patients' perspectives regarding one-on-one peer support.

RESULTS

Two hundred twenty-five of 537 patients diagnosed with breast cancer between 2019 and 2020 completed the questionnaires. Quantitative analysis showed increased symptoms of anxiety and depression among breast cancer patients and lower scores on all EORTC-QLQ-C30 domains compared to the Dutch normative population. Of all patients, 27.6% (95%CI = 0.22-0.34) reported to have unmet needs regarding emotional support and 23.1% (95%CI = 0.18-0.29) reported an unmet need to talk to someone who has experienced breast cancer. For the qualitative analysis, 19 breast cancer patients who were taking part in the one-on-one peer support program participated in three focus groups. Benefits, limitations, and wishes regarding the one-on-one peer support program were discussed.

CONCLUSION

Breast cancer patients showed increased anxiety and depression and lower quality of life, physical, role, emotional, cognitive, and social functioning compared to the Dutch normative population. Almost one-third of breast cancer patients reported unmet needs regarding emotional support and a desire to talk to other breast cancer patients. These (unmet) needs can successfully be met by providing a low-threshold one-on-one peer support program.

Psychometric properties of the Slovenian version of the Cancer Survivors’ Unmet Needs (CaSUN-SL) measure in post-treatment cancer survivors

Background

As the number of cancer survivors is growing, valid instruments for assessing cancer survivors' needs are required. Thus, the aim of this study was to translate and validate the Cancer Survivors Unmet Needs (CaSUN) scale.

Methods

Cancer survivors were recruited from 30 family medicine practices and separated into two samples (sample 1, n = 147; sample 2, n = 148). Factor structure was explored with an exploratory analysis in sample 1 and determined with a confirmatory analysis in sample 2. Psychometric properties were assessed with internal consistency, test–retest reliability and construct validity.

Results

A translation and cultural adaptation of the CaSUN scale resulted in 34 items being included in the final version. The factor structure confirmed the five-factors solution of the CaSUN-SL. Cronbach’s alpha was 0.94 for the CaSUN-SL and ranged from 0.71–0.88 for specific domains. Test–retest reliability showed moderate-high stability over time. The CaSUN-SL significantly and positively correlated with anxiety (r = 0.49), depression (r = 0.44), health-related quality of life (r = 0.36), and negatively with self-perceived health (r =  − 0.36) and resilience (r =  − 0.47), which confirms the construct validity. In addition, we found a significant correlation between unmet needs and age (r =  − 0.29), gender (r = 0.14), cancer stage (r = 0.20), cancer type (r = 0.19), and time since treatment (r =  − 0.20).

Conclusions

Results indicate that CaSUN-SL is a valid and reliable measure to assess the Slovenian cancer survivors’ unmet, met and total needs and can be used for further prospective studies.

Translation and psychometric testing of the Thai version of Cancer Survivors’ Unmet Needs measure among cancer survivors

Objective

To evaluate the psychometric properties of the Thai version of the Cancer Survivors’ Unmet needs (CaSUN-TH) scale among Thai cancer survivors after completion of primary treatment.

Methods

Standardized translation procedures developed the Cancer Survivors’ Unmet Needs into a Thai version (CaSUN-TH). Face validity was evaluated by a group of experts, and a pilot test on 10 cancer patients was conducted to evaluate its readability. A total of 236 cancer survivors who were attending follow-up visits at a cancer hospital in Thailand completed the CaSUN-TH. The internal consistency of the instrument was examined using Cronbach’s α. The association of the CaSUN-TH and its subscales with physical symptoms, QoL, age, gender, and type of cancer were examined for criterion validity and known-group validity. Construct validity was evaluated using confirmatory factor analysis.

Results

The CaSUN-TH showed good readability and high content validity for use as an instrument to assess unmet needs among Thai cancer survivors. Cronbach’s α for the entire scale was 0.95. Confirmatory factor analysis indicated that the five-factor structure of the CaSUN-TH was good fit to the data (CFI ​= ​0.901, SRMR ​= ​0.074, RMSEA ​= ​0.076 [90% confidence interval, 0.066–0.085]). In terms of construct validity, CaSUN-TH scores significantly correlated to other variables hypothesized to influence the level of need, including higher physical symptoms prevalence was related to poor quality of life, and poorer QOL and younger age were associated with a higher level of unmet needs. In addition, the scale was able to differentiate scores between groups, including gender, age, and type of primary cancer, with theoretically hypothesized differences.

Conclusions

The CaSUN-TH demonstrated appropriate psychometric properties for assessing unmet needs in different cancer survivor groups in Thailand. Using the CaSUN-TH can help health professionals in targeting individual survivor needs, bridging the gap between patients’ experiences and their expectations, and improving the quality of cancer survivorship care.

Cultural adaptation and validation of the Survivor Unmet Needs Survey Short-Form among cancer patients in China

AIM

Cancer patients have long been found to have multiple types of unmet needs during their survivorship. Composite psychological instruments are essential for measuring the unmet needs of cancer patients. The objective of this study was to evaluate the psychometric properties of the Short-Form Survivor Unmet Needs Survey (SF-SUNS)-Chinese version.

DESIGN

A cross-sectional survey.

METHODS

The Chinese version was developed using the standard Functional Assessment of Chronic Illness Therapy (FACIT) translation methodology and 428 Chinese cancer patients participated in the survey between 2016-2017. Inter-rater reliability, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were calculated.

RESULTS

Confirmatory factor analysis supported the four-factor structure with good model fit. Cronbach's alpha of 0.894 for the overall scale and intra-class correlation coefficients (0.869-0.884) indicated that reliability was satisfactory. The EFA extracted four factors with eigenvalues greater than 1 and these factors explained 50.68% of the total variance. The Chinese version of SF-SUNS was confirmed to have the potential to become a useful and valid instrument. It could contribute to the assessment of unmet needs among Chinese cancer patients with accuracy and with respect to Chinese culture and context. This measurement of unmet needs may help promote cancer management and nursing quality. Clinical nurses and researchers could use the simple assessment tool to target the individual needs of Chinese cancer patients and then provide more personalized care efficiently.

Evaluation of the Japanese Version of the Cancer Survivors' Unmet Needs Scale

Objective

This study aimed to evaluate the psychometric properties of the Japanese version of the Cancer Survivors' Unmet Needs (CaSUN-J) scale among cancer survivors in Japan.

Methods

The CaSUN-J was developed using standardized translation methodology. Content validity was evaluated by a group of experts, and a pilot test was conducted with a convenience sample of 10 cancer patients. A total of 183 Japanese cancer survivors completed the CaSUN-J. The internal consistency of the scale was examined with Cronbach's α. Construct validity was analyzed using correlations with the physical effects, quality of life (QoL), and age. To assess the factorial validity of the CaSUN-J, confirmatory factor analysis (CFA) was performed.

Results

The CaSUN-J indicated good readability and high content validity for use as an assessment tool among Japanese cancer survivors. All Cronbach's α coefficients were above the minimum acceptable criterion of ≥0.70. For construct validity, higher physical effect scores, as well as poorer QoL scores and younger patients, were significantly positively associated with higher levels of needs. CFA indicated that the five-factor structure of the CaSUN-J was a good fit to the data.

Conclusions

The CaSUN-J can serve as a valid and reliable tool to evaluate unmet needs among Japanese cancer survivors.

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.

Psychometric properties of the Dutch extended Cancer Survivors' Unmet Needs measure (CaSUN-NL)

Information and support needs increase emotional distress and can impede cancer survivors’ adjustment. To investigate the information and support needs of Dutch cancer survivors, the Cancer Survivors’ Unmet Needs measure (CaSUN) was translated into Dutch and applied in two Dutch studies with cancer survivors (N = 255; N = 467). The CaSUN‐NL entailed the original five CaSUN scales, extended with respectively a returning to work and lifestyle scale. This study aimed to determine the psychometric properties of the CaSUN‐NL. To assess validity, a maximum likelihood factor analysis was employed. Construct validity was analysed using Pearson's and Spearman's correlation coefficients. To assess reliability, test–retest (Kappa coefficient) and internal consistency (Cronbach's alpha) values were determined. Factor analysis revealed the original five factors. Test–retest reliability was low (r ≤ .15, 93% retest response). Internal consistency values were high (Cronbach's alpha = 0.92–0.94), except for lifestyle. Significant correlations were found between total number of unmet needs with anxiety (r = .55), depression (r = .49), negative adjustment (r = .50), quality of life (r = −.52) and age (r = −.24). The CaSUN‐NL is valid and reliable to investigate the unmet information and support needs of Dutch cancer survivors.
