Health-Related Quality of Life of Adolescent and Young Adult-Aged Childhood Cancer Survivors in a South African Cohort: A Pilot Study Using the Minneapolis-Manchester Quality of Life Instrument

Purpose: We investigated the health-related quality of life (HRQoL) of an adolescent and young adult (AYA)-aged South African childhood cancer survivor (CCS) cohort. Methods: Participants completed the Minneapolis-Manchester Quality of Life adolescent and adult forms. The overall Cronbach's alpha coefficients were 0.81 (adolescent form) and 0.92 (adult form). The scale-level content validity indexes were acceptable (0.88 and 0.89 for the adolescent and adult forms, respectively). The total domain and overall HRQoL scores were calculated. Results: Sixty-two survivors completed the adolescent form and 30 completed the adult form. The median age was 17.5 years (range 13-34 years), and the median time from diagnosis was 12 years (male:female ratio 1:1.2). Risk factors for poor physical functioning included age at study visit (p = 0.015), solid tumor diagnosis (p = 0.012), radiotherapy (p = 0.021), and surgery (p = 0.006). Six or more late effects impacted most domains negatively; severe late effects (p = 0.020) decreased physical functioning. Lower socioeconomic status was associated with poorer physical (p = 0.006) and cognitive (p = 0.047) functioning. The adult form cohort had poorer psychological (p = 0.014) and social functioning (p = 0.005) and body image (p = 0.016) than the adolescent form cohort. Conclusion: Older age, radiotherapy, surgery, solid tumor diagnosis, and the number and severity of late effects negatively influenced HRQoL in AYA-aged CCSs. A long-term follow-up (LTFU) risk stratification system should include HRQoL status to assist with holistic LTFU care.

Development and psychometric properties of the social adjustment scale for youth cancer survivors in South Korea

Objective

We developed a new scale-the Social Adjustment Scale for Youth Cancer Survivors-and examined its psychometric properties.

Methods

In the scale's development stage, preliminary items were constructed based on the results of a concept analysis of the hybrid model, literature review, and interviews. These items were then reviewed through content validity and cognitive interviews. In the validation stage, 136 survivors were recruited from two children's cancer centers in Seoul, South Korea. An exploratory factor analysis was performed to identify a set of constructs, and validity and reliability were tested.

Results

Starting with 70 items constructed through literature review and interviews with youth survivors, the final scale comprised 32 items. The exploratory factor analysis identified four domains-namely, role achievement in one's present position, harmony in relationships, disclosure and acceptance of cancer history, and preparation and expectation for future roles. Correlations with quality of life indicated good convergent validity (r ​= ​0.82, P ​< ​0.001). The Cronbach's α of the overall scale was 0.95, indicating excellent internal consistency; and the intraclass correlation coefficient was 0.94 (P ​< ​0.001), suggesting high test-retest reliability.

Conclusions

The Social Adjustment Scale for Youth Cancer Survivors exhibited acceptable psychometric properties in measuring the social adjustment of youth cancer survivors. It can be used to identify youths facing difficulty in adjusting to society after treatment and to investigate the effect of interventions implemented to promote social adjustment among youth cancer survivors. Future research is needed to examine the applicability of the scale in patients across diverse cultural backgrounds and healthcare systems.

Assessing Self-concept as a Mediator Between Anger and Resilience in Adolescents With Cancer in Taiwan

BACKGROUND

Anger is considered a common method used by patients to relieve emotional frustrations. However, this emotional response is not a common research focus for adolescents with cancer.

OBJECTIVE

The aim of this study was to determine whether self-concept mediated the relationship between anger and resilience for adolescent patients currently being treated for cancer.

METHODS

A cross-sectional study of 40 adolescents with cancer was conducted. The instruments included the Chinese Beck Self-Concept Inventory, the Chinese Beck Anger Inventory, and the Chinese Resilience Scale. Mediation analysis was also conducted.

RESULTS

The results indicate that (1) variations in anger significantly account for 6.86% of observed variations in self-concept, (2) variations in self-concept significantly account for 52.83% of observed variations in resilience, (3) variations in anger significantly account for 10.96% of observed variations in resilience, and (4) when paths in conditions 1 and 2 were controlled, variations in anger through self-concept significantly account for 54.04% of observed variations in resilience, and variations in anger did not significantly account for observed variations in resilience.

CONCLUSIONS

Gender and age might affect anger control. Despite worse physical functioning and an impacted appearance, participants had normative-to-positive self-concept levels, suggesting that their self-concept might not be affected by cancer. Self-concept might play a mediating role between anger and resilience, thus helping to bridge this knowledge gap.

IMPLICATIONS FOR PRACTICE

The current gap in knowledge regarding the mediating relationship necessitates the implementation of a large-scale study designed to verify the mediating role of self-concept between anger and resilience.

The Minneapolis-Manchester Quality of Life Instrument: reliability and validity of the Adult Form in cancer survivors

PURPOSE

Childhood cancer survivors are at risk for deficits in health-related quality of life (HRQL) as they age. Youth (8-12 years) and adolescent (13-20 years) versions of the Minneapolis-Manchester Quality of Life Instrument (MMQL) have been developed to address survivor-specific issues and are currently in use; the MMQL-Adult Form has now been developed to assess HRQL in childhood cancer survivors aged 21-55 years.

METHODS

The MMQL-Adult Form was administered to 499 adults: 65 cancer patients on-therapy, 107 off-therapy, and 327 healthy controls. Forty-four percent of patients were under 30 years old at cancer diagnosis. Principal components analysis was performed. We evaluated internal consistency reliability, stability (re-administration of the MMQL-Adult Form 2 weeks later), construct validity (concurrent administration of the SF-36), and known-groups validity (score comparisons across the three groups).

RESULTS

Principal components analysis resulted in retention of 44 items across six scales: social functioning, physical functioning, cognitive functioning, outlook on life, body image, and psychological functioning. Internal consistency (Cronbach's α) was 0.80-0.90 for individual scales and 0.95 overall. Strong intraclass correlations (0.98 overall) indicated high stability. The MMQL-Adult Form distinguished between known groups; healthy controls scored better than patients on four of six scales. The MMQL-Adult Form scales correlated highly with similar SF-36 scales, demonstrating construct validity.

CONCLUSIONS

The MMQL-Adult Form is a reliable and valid self-report instrument for measuring multidimensional HRQL in cancer survivors. Development of this instrument ensures availability of a tool enabling cross-sectional and longitudinal assessment of HRQL in childhood cancer survivors as they age.

What Factors Impact Consumer Perception of the Effectiveness of Health Information Sites? An Investigation of the Korean National Health Information Portal

Lay public's concerns around health and health information are increasing. In response, governments and government agencies are establishing websites to address such concerns and improve health literacy by providing better access to validated health information. Since 2011, the Korean government has constructed the National Health Information Portal (NHIP) website run in collaboration with the Korean Academy of Medical Sciences (KAMS). This study therefore aimed to 1) examine consumer use of NHIP, with respect to the usage patterns, evaluation on health information provided, and perceived effectiveness of the site; and 2) identify factors that may impact perceived effectiveness of the site. An online survey was conducted with 164 NHIP users, recruited through a popup window on the main screen of the portal website from October to November 2015. The significant predicting factors supported by the data include the relevance of health information on the site, the usefulness of information in making health decisions, and the effective visualization of information. These factors can inform future efforts to design more effective health information websites, possibly based on metadata systems, to further advance the lay public's information seeking and health literacy.

Health-Related Quality of Life in Brain Tumor Patients Treated with Surgery: Preliminary Result of a Single Institution

Background

Alongside the extent of removal and patients’ survival in the management of brain tumors, health-related quality of life (HRQOL) has become an important consideration. The purpose of this study is to evaluate the change of HRQOL in brain tumor patients before and after surgery and to assess the associated factors that contribute to the change of HRQOL.

Methods

A total of 258 patients who underwent surgical treatment were enrolled in this study. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire 30 (EORTC QLQ-C30) and the 20-item EORTC QLQ-Brain Neoplasm (QLQ-BN20) were used to assess HRQOL. Patients were asked to fill out the questionnaires before and 3-6 months after surgery.

Results

Global QOL (p<0.001) and emotional function (p<0.018) were significantly improved after surgery. Physical function (p=0.015) was significantly aggravated. Among the symptoms, headache, pain and nausea and vomiting were significantly decreased (p<0.01, p=0.041, p<0.001, respectively), while dyspnea, communication deficit and weakness of the legs were increased (p=0.005, p=0.040, and p=0.014, respectively). Preoperative neurologic deficit (p=0.019) and tumor diameter (p=0.016) were significantly related to the patients who showed aggravation of global QOL after brain tumor surgery. In the aggravated global QOL group, common complaints and concerns included role function, appetite loss, financial difficulty and future uncertainty.

Conclusion

In brain tumor patients, HRQOL has improved after surgery. Role function, appetite loss, financial difficulty and future uncertainty were important factors for HRQOL in brain tumor patients treated with surgery. Although there is National Health Insurance and Medical Aid program in Korea, financial difficulty and future uncertainty are much more important in influencing QOL than previously thought. The results of this short-term follow up preliminary study suggest that several factors were related to HRQOL, Further research is needed to evaluate the long term change of HRQOL and enhance the global QOL by analyze related factors.

Psychometric evaluation of the Mental Health Continuum-Short Form (MHC-SF) in Chinese adolescents - a methodological study

BACKGROUND

In epidemiological surveillance of mental health there is good reason to also include scales that measure the presence of well-being rather than merely symptoms of ill health. The Mental Health Continuum-Short Form (MHC-SF) is a self-reported scale to measure emotional, psychological and social well-being and conduct categorical diagnosis of positive mental health. This particular instrument includes the three core components of the World Health Organization's definition of mental health and had previously not been psychometrically evaluated on adolescents in China.

METHODS

In total 5,399 students (51.1% female) from schools in the urban areas of Weifang in China were included in the study (mean age = 15.13, SD = 1.56). Participants completed a comprehensive questionnaire with several scales, among them the MHC-SF. Statistical analyses to evaluate reliability, structural validity, measurement invariance, presence of floor and ceiling effects and to some extent external validity of the MHC-SF were carried out.

RESULTS

The Cronbach's α coefficients for sub-scales as well as the total scale were all above 0.80 indicating good reliability. Confirmative factor analysis confirmed the three-dimensional structure of the Chinese version of MHC-SF and supported the configural and metric invariance across gender and age. Noteworthy ceiling effects were observed for single items and sub-scales although not for the total scale. More importantly, observed floor effects were negligible. The stronger correlation found between MHC-SF and Minneapolis-Manchester Quality of Life Instrument (as measure of positive mental health) than between MHC-SF and Hospital Anxiety Depression Scale (as measure of mental illness and distress) yielded support for external validity.

CONCLUSION

In conclusion, the main findings of this study are in line with studies from other countries that evaluated the psychometric properties of the MHC-SF and show that this instrument, that includes the three core components of the WHO definition of mental health, is useful in assessing positive adolescent mental health also in China.

The Mediating Role of Resilience on Quality of Life and Cancer Symptom Distress in Adolescent Patients With Cancer

Understanding how cancer symptom distress and resilience contribute to quality of life (QoL) in adolescent cancer and may potentially help these patients achieve better health-related outcomes. The objective of this study was to describe cancer symptom distress, QoL, and resilience in adolescents with cancer and to determine whether resilience is a mediating variable. Forty adolescent cancer patients were recruited, and data were collected via a demographic questionnaire, the Cancer Symptom Distress Scale, the Resilience Scale, and the Minneapolis-Manchester Quality of Life Scale. Pearson's correlation, multiple regressions, and the Sobel test were conducted. Both resilience and cancer symptom distress were regressed against QoL, accounting for 62.1% of observed variation in QoL scores. The bootstrap result estimated the true indirect effect between -.0189 and -.0024, with a 95% confidence interval. Resilience mediates the relationship between cancer symptom distress and QoL. Clinical use of a resilience measure, for example to use in developing and evaluating interventions focused on enhancing resilience, may be practical for nurses.

Development and evaluation of Korean version of Quality of Sexual Function (QSF-K) in healthy Korean women

This study was done to develop a Korean version of the Quality of Sexual Function (QSF-K) and evaluate the validity and reliability of the QSF-K. The participants were 220 women who visited the Center for Uterine Cancer at the National Cancer Center in Korea. Participants completed the scale once and then again at a two to four week interval. The QSF-K, Female Sexual Function Index (FSFI) and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30) were used in this study. Receiver operating characteristics (ROC) curve, area under the ROC curve (AUC), intraclass correlation coefficients (ICC), and Cronbach's alpha were analyzed. In the analysis of the reliability, Cronbach's alpha was 0.83 and the ICC was 0.70. The validity measured with the AUC of the QSF-K comparing the FSFI and Global Health/QOL of the EORTC-QLQ-C30 was 0.717 and 0.728, respectively. Specifically, the AUC of the sexual activity level of the QSF-K was 0.838 in the FSFI comparison. The AUC of the psycho-somatic QOL of the QSF-K was 0.758 in the Global Health/QOL of the EORTC-QLQ-C30 comparison. Approximately half of the women (51.8%) had mild complaints/problems. The Korean version of the QSF was developed and validated.
