The Cancer Loneliness Scale and Cancer-related Negative Social Expectations Scale: development and validation

Development and Validation of a New Measurement Scale for Existential Loneliness

This article deals with the development and initial validation of the Existential Loneliness Scale (ELS). An initial pool of 40 items, generated based on literature review, qualitative studies, and previously developed scales, was evaluated by the experts' judgment, so 30 items were retained and then administered to an Iranian sample of 433 youth and adult participants aged 20 to 85 years. Participants also completed other measures relevant for construct validity: Existential Loneliness Questionnaire (ELQ), De Jong Gierveld Loneliness Scale (DJGLS-6), Existential Anxiety Questionnaire (EAQ), Meaning in Life Questionnaire (MLQ), Beck Depression Inventory (BDI-13), and Satisfaction with Life Scale (SWLS). Exploratory factor analysis and parallel analysis showed strong evidence of unidimensionality. This result was also supported by confirmatory factor analysis test. Finally, 19 items were kept, which were free from DIF by gender and by marital status. The scale had high internal consistency (α = .95 and ω = .95) and adequate test-retest reliability with a 1-month interval (r = .74). Examination of the ELS' correlation with criterion measures indicated that the scale has good concurrent, discriminant, and convergent validity. Findings revealed the ELS as a reliable, valid, and suitable instrument to measure existential loneliness in the Iranian adult population.

Adaptation and study protocol for harvest for health together Arizona: A mentored community garden intervention for survivors of cancer

Background

Current health behavior recommendations for skin cancer prevention, treatment, and survivorship are the same for survivors of other cancers; they include eating a healthy diet, being physically active, maintaining a healthy weight, and minimizing ultraviolet (U.V.) exposure. Few interventions exist to support health behaviors beyond U.V. exposure. We adapted Harvest for Health, a home-based mentored gardening intervention for cancer survivors, for implementation in Arizona as a community-based intervention.

Methods

Stakeholder-informed adaptations for Harvest for Health Together Arizona (H4H2-AZ) included updating intervention materials to be relevant to the arid desert environment, emphasizing the importance of sun safety in cancer survivorship, and shifting from a home-based to a community-based delivery model. Participants will be enrolled in cohorts aligned with growing seasons (e.g., spring, monsoon, fall) and matched to an individual 30 ft2 community garden plot for two growing seasons (6 months). Original intervention components retained are: 1) Master Gardeners deliver the intervention providing one-to-one mentorship and 2) gardening materials and supplies provided. This pilot six-month single-arm intervention will determine feasibility, acceptability, and appropriateness of an evidence-based adapted mentored community gardening intervention for survivors of skin cancer as primary outcomes. Secondary outcomes are to explore the effects on cancer preventive health behaviors and health-related quality of life.

Discussion

This pilot single-arm intervention will determine feasibility, acceptability, and appropriateness of an evidence-based adapted mentored community gardening intervention for survivors of skin cancer. If successful, the intervention could be widely implemented throughout existing Master Gardener programs and community garden networks for survivors of other cancers.

Translation and Validation of the Greek Version of the Questionnaire for Assessing Fear of Radiotherapy in Oncology Patients

This study aims to validate the Greek translation of the Questionnaire for Assessing Fear of Radiotherapy in Oncology Patients (QAFRT). Conducted as a cross-sectional pilot study, it involved 149 cancer patients from two radiotherapy departments in Thessaloniki, Greece. The sample included patients with various cancer types and stages, all of whom were undergoing radiation treatment. The QAFRT, originally containing 15 items measured on a Likert scale, was translated into Greek using the back-translation method. Exploratory factor analysis was performed on the translated version, resulting in a refined 13-item questionnaire encompassing four factors: fear of radiotherapy effectiveness, fear of illness during radiotherapy, fear of radiotherapy's impact on daily life, and fear of side effects and relationships. The reliability of the QAFRT was confirmed with Cronbach's α of 0.82 and intraclass correlation coefficient coefficients ranging from 0.92 to 0.98. The study concludes that the Greek version of the QAFRT is a reliable and valid tool for assessing the fear of radiotherapy in cancer patients, highlighting the need for adequate psychological support for those with high levels of fear.

Factors Influencing Social Isolation among Cancer Patients: A Systematic Review

(1) Background: Social isolation, which has numerous adverse effects on health status, is prevalent among cancer patients. This review proposes to identify the influencing factors of social isolation among cancer patients. (2) Methods: Articles published in English or Chinese from six electronic databases before December 2023 were identified via a systematic search. A manual search was also performed. (3) Results: Twenty-eight studies were identified in this systematic review. The factors associated with social isolation can be summarized into the following categories: demographic characteristics, having cancer, health status, coping, social support and social interaction. Despite the heterogeneity, 20 factors were significantly associated with social isolation, including age, gender, comorbidity burden, education level, residence, medical insurance, occupation status, personality, race, smoking status, having children, not living alone, household income level, marital status, the role of primary caregiver, physical health status, mental health status, social health status, coping styles, and the level of social support and social interaction. (4) Conclusions: The systematic review showed that cancer patients' social isolation was influenced by their demographic characteristics, cancer-related factors, physical condition, psychological status, social health status, coping styles, and level of social support and social interaction. In addition, future group intervention could be considered to improve social isolation.

The Assessment of Social Isolation and Loneliness in Cancer Patients and Survivors in the Pre-COVID-19 Period: A Systematic Review

BACKGROUND

In the context of cancer research, identifying social isolation and loneliness is a priority given how both exacerbate poor outcomes and lead to increased mortality in oncological populations. The purpose of this systematic review is to identify all quantitative instruments that have been used to assess either social isolation or loneliness in patients previously or currently diagnosed with cancer in the pre-COVID-19 period.

METHOD

PubMed (Web), Scopus, CINAHL, and PsycINFO were searched on August 22, 2019. All databases were searched from inception with no filters applied. The search strategies included terms that captured the following concepts: instruments/tools, social isolation or loneliness, and cancer.

RESULTS

A total of 289 titles/abstracts were returned. Upon review, 114 titles/abstracts were deemed to be potentially eligible and the full text was retrieved. Of the 114 full texts, 69 articles met inclusion criteria and comprised the final sample. Publications span years 1980 through 2019, with the majority (71%) occurring in the last decade prior to this review, between 2009 and 2019. Average age of the study samples, with few exceptions, was often over 50 years old. Many studies used all-female samples, while only one study used an all-male sample. The most common cancer diagnosis of participants was breast cancer. The most common measure was the UCLA Loneliness Scale, used in 22 studies. Most measures we identified were used only once, and 11 measures were used 2-3 times. When the information was given, response ranges were always Likert-type scales most often ranging from 1-4 or 1-5, and sometimes from 1-10 possible response options. In terms of psychometrics, test-retest reliability and validity were rarely reported; by contrast, internal consistency (Cronbach's alpha) was reported more than half of the time (60.9%).

CONCLUSION

When selecting a measure to assess loneliness in cancer populations, the UCLA Loneliness Scale is both psychometrically strong and versatile across patients with different cancers, ages, and racial backgrounds. When selecting a measure to assess social isolation in cancer populations, both the PROMIS-SF V 2.0 social isolation and the Berkman-Syme Network Index are brief and have been used in patients with non-White racial backgrounds.

Association between perceived stress, loneliness and sleep disorders among breast cancer patients: the moderating roles of resilience

Sleep disorders are prevalent and often neglected among breast cancer patients. This study aimed to identify the association among perceived stress, loneliness, resilience and sleep disorders and to further explore whether resilience could be a moderator in the association between them and sleep disorders. A cross-sectional study was conducted by 492 female breast cancer patients. Patients were asked in response to the questionnaires including the Pittsburgh Sleep Quality Index, Perceived Stress Scale-10, the Three-Item Loneliness Scale and Resilience Scale-14. The association among perceived stress, loneliness, resilience and perceived stress/loneliness × resilience interaction with sleep disorders were examined by hierarchical multiple regression analysis. The interaction was visualized by using simple slope analysis. 36.58% of the female breast cancer patients reported sleep disorders in our study. Perceived stress and loneliness were related to sleep disorders. Resilience could moderate the relationship between them and sleep disorders. When resilience was higher, perceived stress and loneliness had a weaker impact on sleep disorders. Medical staff should systematically evaluate the internal environmental factors related to patients' sleep quality and help patients relieve their emotional distress caused by the disease through positive psychological guidance.

Factors Associated With Loneliness Among Chinese Patients With Cancer: A Cross-sectional Study

BACKGROUND

Loneliness has a significant impact on the physical and psychological well-being of patients with cancer. However, the specific factors contributing to loneliness among patients with cancer within the context of Chinese culture remain poorly understood.

OBJECTIVE

The objective of this study was to identify the factors associated with loneliness among patients with cancer in China.

METHODS

A cross-sectional study was conducted using convenience sampling, involving a sample of 205 patients with cancer from a tertiary hospital in Guangzhou, China. Participants completed several validated questionnaires, including the Cancer Loneliness Scale (CLS), Hospital Anxiety and Depression Scale (HADS), Cancer-Related Negative Social Expectations Scale (C-rNSES), and Social Support Rating Scale (SSRS). Multiple linear stepwise regression analysis was employed to explore the relationships between loneliness and psychosocial factors.

RESULTS

The median score for loneliness among patients with cancer was 13, with an interquartile range of 8. The multiple linear stepwise regression analysis revealed that negative social expectations, social support, and depression were significantly associated with loneliness in this population. Collectively, these factors accounted for 50.1% (R2 = .501) of the variance in loneliness.

CONCLUSIONS

The findings of this study highlight the importance of addressing negative social expectations and depression and improving social support to prevent or reduce loneliness among patients with cancer. Health care providers should consider these factors when developing interventions aimed at preventing or alleviating loneliness in this population.

The relationship between loneliness, psychological resilience, quality of life and taste change in cancer patients receiving chemotherapy

PURPOSE

This study aimed to determine the correlation between taste change, nutritional intake and quality of life in cancer patients receiving chemotherapy. A total of 610 (F = 314, M = 296) volunteers aged 19 and 65 who received outpatient chemotherapy treatment participated in the study.

METHODS

Individuals' general information was obtained, anthropometric measurements were carried out, malnutrition status (Patient-Generated Subjective Global Assessment PG-SGA), loneliness (Cancer Loneliness Scale), psychological resilience (Psychological Resilience Scale), quality of life (Quality of Life Scale (EORT QLQ-C30) and taste changes were scrutinized [Chemotherapy-Induced Taste Alteration Scale (CiTAS)].

RESULTS

There was a negative correlation between the Cancer Loneliness Scale and PG-SGA and General Health Status (r = -0.494, p = 0.000; r = -0.406, p = 0.000) and a positive correlation with Symptom Scales (r = 0.484, p = 0.000; r = 0.506, p = 0.000) (p < 0.05). There was a positive correlation between the Psychological Resilience Scale and General Health Status (r = 0.393, P = 0.000), Functional Scales (r = 0.349, P = 0.000), and a negative correlation between Symptom Scales (r = -0.302, p = 0.000) (p < 0.05). 70.9% of men and 70.7% of women had severe malnutrition. General Taste Changes, General Health and Symptom Scale values were significant predictors of severe malnutrition status (p < 0.05).

CONCLUSION

The symptoms that develop during the treatment process cause many psychological problems. Before starting treatment, patients should be evaluated comprehensively, depression anxiety levels and quality of life levels should be determined, and precautions should be taken accordingly.

[Experiences of patients with cancer during the first COVID-19 lockdown: What was the impact on the patients' healthcare pathway, mental condition, and access to supportive care in cancer?]

INTRODUCTION

The COVID-19 pandemic disrupted the organisation of the healthcare system. Very little data is available regarding the impact of the COVID-19 pandemic on patients' perceptions of their healthcare pathway. The objective of this survey was to evaluate cancer patients' perceptions of the impact of the first COVID-19 lockdown on continuity of care, their mental condition, as well as their access to Supportive Care in Cancer (SCC).

METHODS

Between June 2nd and 30th, 2020, an anonymous questionnaire was sent out to the patients who visited 17 healthcare establishments in the Centre-Val de Loire region.

RESULTS

Our survey questioned 861 patients, amongst which 839 were selected. The population was predominantly female (58%). Breast cancer was the most represented (27%). Approximately three patients out of four considered that their care was maintained during the lockdown. In total, 348 patients (44%) reported an altered mental status. Approximately 1/4th of patients benefited from SCC. More than half of the patients felt that SCC was not relevant to their situation, although 40% of these patients expressed mental issues.

CONCLUSION

Our survey highlighted a negative impact on patients' mental condition and a low use of SCC in spite of existing needs. This demonstrates the necessity of evaluating the patients' needs and offering adequate SCC at various stages of the healthcare pathway, as well as the need for a clearly identifiable offer for the healthcare professionals and the patients.

Effect of Group Logotherapy on Anxiety About Death and Existential Loneliness in Patients With Advanced Cancer: A Randomized Controlled Trial

BACKGROUND

Although logotherapy has been shown to relieve other psychological symptoms of patients with cancer, no studies have specifically investigated the effect of logotherapy on anxiety about death and existential loneliness in these patients.

OBJECTIVE

The aim of this study was to determine the effect of group logotherapy on anxiety about death and existential loneliness in patients with advanced cancer.

METHODS

Sixty-three patients who were in the advanced stage of cancer were recruited from 2 hospital oncology services and were randomly assigned to either experimental (n = 31) or control group (n = 32). The intervention group received 10 weekly 2-hour group logotherapy. Templer's Death Anxiety Scale and ELQ were completed pre- and posttreatment.

RESULTS

A 2 × 2 mixed analysis of variance was used to determine the effect of the treatment on each of the dependent variables. The analyses revealed that patients in the logotherapy group reported a significant decrease in anxiety about death and existential loneliness after (vs before) the treatment. No significant decreases were observed in the waitlist control group.

CONCLUSIONS

These results have implications for treating death anxiety and feelings of existential loneliness among patients with advanced cancer. They suggest that group logotherapy is highly effective in reducing these existential concerns. Limitations and avenues for future research are discussed.

IMPLICATIONS FOR PRACTICE

The study emphasizes that group logotherapy can be considered in oncology care programs by healthcare professionals and in educational curriculums and is suggested for use among caregivers and patients with advanced cancer.

Coping strategies and considerations regarding low anterior resection syndrome and quality of life among patients with rectal cancer; a qualitative interview study

Introduction

Low anterior resection syndrome (LARS) is defined as disordered bowel function following rectal resection, which is detrimental to quality of life (QoL). A recent international consensus definition of LARS stresses the importance of focusing on both the symptoms and the consequences that the symptoms have for the individual patient as studies indicate that LARS has a negative impact on patients’ QoL. However, an ongoing PROM study investigating late sequelae after rectal cancer finds that a minor proportion of patients scoring major LARS experience none or only little impact on quality of life

Aim

The aim of this study was to identify patients’ considerations and coping strategies to establish why the burden caused by major LARS had little or no influence on their QoL.

Materials and methods

This was a qualitative interview study based on 21 semi-structured individual telephone interviews with patients treated for rectal cancer. Data were analysed using a hermeneutic inspired thematic analysis.

Results and conclusion

Three themes emerged from the analysis; Adapting new life situation, Altering life perception and the Importance of relationships. Major LARS and its consequences following rectal cancer may be managed or altered by adopting problem-focused and emotion-focused coping strategies. Maintaining a positive attitude and having a good network of family and friends constitute a surplus, allowing patients to cope with the need for changed behaviour and appreciate the life that they have been given. Accepting that major LARS and its consequences cause limitations in life allowed patients to change their normality threshold over time.

Impact of Loneliness on Functioning in Lung Cancer Patients

Lung cancer is the leading cause of cancer death and carries a greater degree of stigma. Lung cancer stigma contributes to social isolation and increases loneliness, which has an impact on quality of life, increases depressive symptoms and hence affects all aspects of functioning. Functioning is assessed in five dimensions (physical, psychological, cognitive, social and life roles). The aim of the study was to assess the impact of loneliness on the functioning, nutritional status and quality of life of patients with lung cancer.

METHODS

The survey study was conducted among 310 lung cancer patients. The patients were asked to complete the Mini-MAC, HADS-M, MNA, EORTC QoL, AIS and VAS questionnaires.

RESULTS

In total, 136 patients were lonely and 174 were married or in a relationship. Lonely patients had significant difficulty accepting their illness and demonstrated higher levels of depression. The factors most strongly associated with loneliness were being unemployed, age 61 or over and a less score in the constructive coping strategies.

CONCLUSIONS

Loneliness is a significant factor affecting the functioning of patients with lung cancer. It increases the risk of anxiety and depression, reduces levels of illness acceptance, reduces levels of constructive coping and increases the risk of malnutrition.

The Loneliness of Migraine Scale: A Development and Validation Study

Patients with migraine often isolate themselves during their attacks. This disease-related loneliness seems to reverberate interictal, as some patients report failing relationships, losing jobs, or suffering from reduced social contacts. We developed a 10-item self-report questionnaire, the loneliness of migraine scale (LMS), and conducted an online survey. The questionnaire comprised diagnostic questions for migraine, the loneliness of migraine scale, the Generalized Anxiety Disorder Scale (GAD-7), the Patient Health Questionnaire (PHQ-8), and the Headache Attributed Lost Time Index (HALT-90). We computed item statistics, the psychometric properties of the LMS and assessed correlations between loneliness, migraine days, anxiety, and depression. We included 223 participants with (probable) migraine, reporting 8 ± 6 headache days with a disease duration of 11 ± 11 years. The mean scores of the HALT were 88 ± 52, of the GAD-7 10 ± 5, for PHQ-8 11 ± 6, and of the LMS 28.79 ± 9.72. Cronbach’s alpha for all ten items was 0.929. The loneliness scale correlated with the GAD-7 (r = 0.713, p < 0.001), with the PHQ-8 scale (r = 0.777, p < 0.001) and with migraine days (r = 0.338, p < 0.001). The LMS is a reliable and valid questionnaire measuring the loneliness of migraine patients. Feelings of loneliness were common and correlated highly with migraine days, anxiety, and depression.

Comparing Fatigue, Loneliness, Daytime Sleepiness, and Stress in Younger and Older Breast Cancer Survivors: A Cross-Sectional Analysis

BACKGROUND

Breast cancer treatment can negatively affect psychosocial outcomes for breast cancer survivors (BCS), but these outcomes present differently for younger and older survivors.

OBJECTIVES

The objective of this study was to compare psychosocial outcomes between younger and older BCS and identify predictors of loneliness in younger BCS.

METHODS

This cross-sectional descriptive study of 90 BCS evaluated data on sociodemographic and clinical characteristics and self-reported measures of psychosocial outcomes (fatigue, depressive symptoms, anxiety, loneliness, daytime sleepiness, and stress). Participants were dichotomized into two groups by age (aged less than 50 years and aged 50 years or older). Descriptive statistics, bivariate correlations, and multiple regression were also examined.

FINDINGS

Younger BCS reported greater fatigue, loneliness, daytime sleepiness, and stress than older BCS. No between-group differences were found in depressive symptoms or anxiety. Having children and less time since chemotherapy completion were significant predictors of less loneliness in younger BCS.

Not as simple as "fear of the unknown": A qualitative study exploring anxiety in the radiotherapy department

OBJECTIVE

Little is understood about the anxiety experienced by cancer patients undergoing radiotherapy or investigative imaging. Our aim was to identify sources of anxiety, the points along the cancer journey where anxiety occurred and methods to alleviate it.

METHODS

Six focus groups were conducted with cancer patients (n = 17), caregivers (n = 3) and healthcare practitioners (HCPs; n = 10) in the radiotherapy department. Patients described specific elements in the care pathway which induced anxiety, while HCPs focused on their perception of the patient experience. Thematic analysis was used to analyse data.

RESULTS

Three broad themes emerged: The Environment, The Individual and The Unknown. The physical environment of the hospital, inside the scanner for example, emerged as a key source of anxiety. The impact of cancer on patients' individual lives was significant, with many feeling isolated. The majority of participants described anxiety associated with the unknown. HCPs reported difficulty in identifying the anxious patient.

CONCLUSIONS

Anxiety is experienced throughout the cancer pathway. Common sources include the physical environment and the uncertainty associated with having cancer. Identifying both anxiety-inducing factors, and the anxious patients themselves, is crucial to enable targeted interventions to alleviate anxiety.

Preoperative concerns of patients undergoing general surgery

OBJECTIVES

This qualitative review aims to provide a clearer understanding of concerns general surgery (GS) patients face in the preoperative period.

METHODS

Medline, CINAHL, PsycINFO and Web of Science were searched for articles describing the preoperative concerns of GS patients. Qualitative and mixed method studies were included. Key quotes were extracted, coded, and thematically analyzed according to Thomas and Harden's methodology.

RESULTS

27 articles were included. Three main themes were generated: (1) lead-up to surgery, (2) postoperative recovery process and (3) standard of care. While waiting for surgery, patients were often shrouded with uncertainty and concerned themselves with the potential impacts of their disease and surgery on their wellbeing and recovery. Furthermore, patients' trust and confidence in Healthcare Professionals (HCPs) was compromised when standard of care was perceived to be deficient, resulting in doubts about HCPs' credibility and capabilities.

CONCLUSION

Patients' preoperative concerns often stem from the uncertainty and unfamiliarity surrounding surgery. To address this, a combination of effective preoperative education, individualised communication and involvement of social support should be considered.

PRACTICE IMPLICATIONS

Preoperative concerns can negatively impact patients and effective interventions will result in a better perioperative experience with fewer negative consequences arising from patients' fear and anxiety.

Symptom experiences in post-treatment cancer survivors: associations with acceptance and commitment therapy constructs

PURPOSE

Acceptance and Commitment Therapy (ACT) has improved symptom and quality-of-life outcomes in pilot research with post-treatment cancer survivors. To further test the ACT model, the present study examined relationships between ACT constructs and subgroups of post-treatment survivors based on the severity of common symptoms.

METHODS

Survivors who had completed primary treatment for stage I or II cancer (N = 203) participated in this one-time survey. Latent class analysis (LCA) was used to identify subgroups of survivors based on the severity of fatigue, sleep disturbance, pain, anxiety, and depressive symptoms. Multinomial logistic regressions employing Vermunt's 3-step approach were used to examine ACT constructs (e.g., mindfulness, acceptance, values progress) as correlates of survivor subgroups based on symptoms.

RESULTS

The LCA showed three survivor classes: (1) mild-to-moderate levels of all symptoms except for normal pain intensity; (2) mild anxiety, moderate fatigue, and normal levels of all other symptoms; and (3) normal levels of all symptoms. Lower mindfulness, acceptance, and values progress and higher cognitive fusion, psychological inflexibility, and values obstruction were associated with a greater likelihood of being in class 1 or 2 than in class 3.

CONCLUSION

Findings are consistent with the ACT model. Survivors with greater symptom burden reported greater withdrawal from personally meaningful activities and less acceptance of their cancer diagnosis and internal experiences (e.g., thoughts, feelings, symptoms). Findings provide strong justification for further testing of ACT to reduce symptom-related suffering in cancer survivors.

Seven Shades of Black Thoughts: COVID-19 and Its Psychological Consequences on Cancer Patients

An outbreak of novel coronavirus disease (COVID-19) that started in China at the end of 2019 has rapidly spread all over the world. COVID-19 is plaguing people not only physically but also psychologically, and cancer patients are particularly exposed to this emotional threat. Herein, we describe the psychological threats posed by COVID-19 to cancer patients. Our analysis is based on the concerns of our patients during our daily clinical interactions in both outpatient and inpatient settings. We have summarized the patients' psychological issues: logistic overload, loneliness, fear, oxymoronic thoughts, helplessness, frustration, and emotional siege. We describe these psychological threats, provide clinical context for them, and offer practical suggestions for managing them, for the benefit of patients, their caregivers, and clinicians. Our hope is that, by sharing our clinical experience, we can help other oncologists increase their awareness of the psychological impact of the pandemic on cancer patients and implement solutions. Managing these challenges now should translate into improved standards of care when this infective storm is over. Paradoxically, COVID-19 could be an opportunity to learn how to better manage cancer care.

Cancer-related loneliness mediates the relationships between social constraints and symptoms among cancer patients

Cancer patients have high rates of persistent and disabling symptoms. Evidence suggests that social constraints (e.g., avoidance and criticism) negatively impact symptoms, but pathways linking these variables have yet to be identified. This study examined whether cancer-related loneliness (i.e., feeling socially disconnected related to having cancer) mediated the relationships between social constraints and symptoms (i.e., pain interference, fatigue, sleep disturbance, and cognitive complaints) in patients with various cancers (N = 182). Patients (51% female, mean age = 59) were recruited from the Indiana Cancer Registry and completed questionnaires assessing social constraints, cancer-related loneliness, and symptoms. Structural equation modeling was used to evaluate the hypothesized relationships among variables. The model demonstrated good fit. Consistent with our hypothesis, cancer-related loneliness mediated the relationships between social constraints and each symptom. Findings suggest that addressing cancer-related loneliness in symptom management interventions may mitigate the negative impact of social constraints on outcomes.
