Abstract
PURPOSE The aim of the present study was to investigate the relationships between fear of cancer recurrence and quality of life in patients with prostate cancer. A model based on Lazarus' and Folkman's theory tested the specific hypothesis: fear of cancer recurrence has a direct and indirect effect on quality of life mediated by coping strategies. METHODS A questionnaire survey was conducted on 305 patients with prostate cancer who underwent radical surgery, including demographic information, FoP-Q-SF (Fear of Progression Questionnaire), MCMQ (The Medical Coping Modes Questionnaire), QLQ-C30 (Questionnaire for Quality of Life Assessment in patients with cancer, version 3.0), and a mediator model was tested using the PROCESS macro for SPSS. RESULTS The total FoP-Q-SF score of 305 postoperative prostate cancer patients was 34.3 ± 5.856, with approximately 41.6% of the patients scoring higher than 34. There were significant indirect effects of fear of cancer recurrence on global health status through face [a1b1; 0.0394, Boot CIs 0.0025, 0.0819] and yield [a3b3; -0.1075, Boots CIs - 0.1657, -0.0557] but not for evasive [a2b2; 0.0235; Boots CIs - 0.057, 0.0508]. CONCLUSIONS Coping strategies are the most important mediating factors between fear of cancer recurrence and QOL among patients with prostate cancer. Our results support the proposed conceptual model, based on Lazarus' and Folkman's theory. Medical personnel need to develop corresponding intervention measures based on the different coping methods of patients, promote disease recovery, and improve postoperative quality of life.

Abstract
PURPOSE Fear of progression (FoP) is a substantial concern for family caregivers of cancer survivors and is related to a number of adverse outcomes, including increased mental distress and worse quality of life. Previous research has revealed that health anxiety (HA) contributes to fear of relapse, but cognitive factors underlying establishing and maintaining FoP in mothers of cancer patients have not been examined. In this study, we were looking to investigate this association. METHODS We used the computerized interpretation bias (IB) assessment to investigate the biased interpretation of ambiguous bodily information and its association with FoP through HA among 69 mothers of cancer patients and 42 mothers of healthy kids. RESULTS Mothers of cancer patients interpreted more negatively ambiguous bodily symptoms than mothers of healthy kids. Moreover, they had higher levels of HA and FoP and lower quality of life than the healthy group. Also, among mothers of cancer patients, the relationship between negative IB and FoP is mediated by their HA. CONCLUSIONS The findings of this study imply that negative IB may contribute to increased HA, which in turn contributes to higher levels of FoP among the mothers of cancer patients, which may reduce the quality of life of their children. IMPLICATIONS FOR CANCER SURVIVORS From these findings, we propose that changing HA through modification of IB might lower the FoP in mothers of kids with cancer and improve the mother and child's quality of life.

Abstract
PURPOSE Fear of progression or recurrence is assumed as a rational response to the threat of cancers and types of cancer treatment. However, the elevated levels of fear in cancer patients can become dysfunctional. Therefore, a valid and reliable questionnaire is unquestionably required for this purpose. This study aimed to translate the Fear of Progression Questionnaire and evaluate its psychometric properties for patients with gastrointestinal cancers in Iran. METHODS In this study with a methodological research design, a total number of 430 patients affected with gastrointestinal cancers referring to Northern Iran completed the 43-item Fear of Progression Questionnaire. The psychometric properties of the questionnaire were evaluated, including the face validity and content validity. Then construct validity was assessed using exploratory and confirmatory factor analyses. Finally, the reliability was assessed using internal consistency (Cronbach's alpha) and stability (intraclass correlation coefficient). RESULTS Based on the result of the face and content validity, no items were revised and removed. The five extracted factors included were emotional response, employment, and loss of independence, economy/family, and coping. These factors explained 37% of the total variance of Fear of Progression Questionnaire. Reliability (by Cronbach's alpha) and stability (test retest was evaluated by intraclass correlation coefficient) were more than 0.7. CONCLUSION The study results revealed that the Persian version of the Fear of Progression Questionnaire had acceptable reliability and validity for cancer patients in Iran. Emotional responses explained the most variance of the concept of fear of progression among cancer patients.

Abstract
Introduction Fear of progression (FoP) is associated with the quality of life and behavioral change in acute pancreatitis (AP) patients, but lack of assessment tools. Aim This study aimed to develop and evaluate the psychometric properties of the Fear of Progression Questionnaire-Short Form in AP patients (AP-FoP-Q-SF). Methods Internal consistency, factorial structure, convergent validity, and criterion validity of AP-FoP-Q-SF were assessed. A receiver operating characteristic (ROC) curve analysis was performed to identify the cutoff value for high FoP. Associations between patient variables and FoP were evaluated using multiple logistic regression. Wilcox rank sum test was used to analyses the costs and length of hospital stay of the patients with high FoP. Results The two-factor structure showed a good fit. Internal consistency was acceptable (Cronbach's α = 0.771). The cutoff of 26 identified 35.3% of patients with high FoP. High FoP scores were associated with age (OR = 0.96, 95%CI: 0.94-0.98), recurrence times (OR = 1.22, 95%CI: 1.02-1.45) and anxiety (OR = 1.27, 95%CI: 1.16-1.40). Patients with high FoP spent more cost and time in the hospital. Conclusions The AP-FoP-Q-SF is a good FoP tool for AP patients in China. Implications for practice Clinicians can use the AP-FoP-Q-SF to assess FoP and take promotion programs to avoid worse effects.

Abstract
OBJECTIVE Fear of cancer recurrence (FCR) is reported by both cancer survivors and caregivers however less is known about caregiver FCR. This study aimed to (a) conduct a meta-analysis to compare survivor and caregiver FCR levels; (b) examine the relationship between caregiver FCR and depression, and anxiety; (c) evaluate psychometric properties of caregiver FCR measures. METHODS CINAHL, Embase, PsychINFO and PubMed were searched for quantitative research examining caregiver FCR. Eligibility criteria included caregivers caring for a survivor with any type of cancer, reporting on caregiver FCR and/or measurement, published in English-language, peer-review journals between 1997 and November 2022. The COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) taxonomy was used to evaluate content and psychometric properties. The review was pre-registered (PROSPERO ID: CRD42020201906). RESULTS Of 4297 records screened, 45 met criteria for inclusion. Meta-analysis revealed that caregivers reported FCR levels as high as FCR amongst survivors, with around 48% of caregivers reporting clinically significant FCR levels. There was a strong correlation between anxiety and depression and medium correlation with survivor FCR. Twelve different instruments were used to measure caregiver FCR. Assessments using the COSMIN taxonomy revealed few instruments had undergone appropriate development and psychometric testing. Only one instrument met 50% or more of the criteria, indicating substantial development or validation components were missing in most. CONCLUSIONS Results suggest FCR is as often a problem for caregivers as it is for survivors. As in survivors, caregiver FCR is associated with more severe depression and anxiety. Caregiver FCR measurement has predominately relied on survivor conceptualisations and unvalidated measures. More caregiver-specific research is urgently needed.

Illness perceptions, fear of progression and health-related quality of life during acute treatment and follow-up care in paediatric cancer patients and their parents: a cross-sectional study. BMC Psychol 2023; 11:44. [PMID: 36782336 PMCID: PMC9926758 DOI: 10.1186/s40359-023-01078-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Accepted: 02/06/2023] [Indexed: 02/15/2023] Open
Abstract
BACKGROUND This study examines the role of illness perceptions and fear of progression (FoP) in paediatric cancer patients and their parents for patient's health-related quality of life (HRQoL), controlling for sociodemographic and medical variables. 4-18-year-old patients in acute treatment or follow-up care and one parent were examined. METHODS N = 46 patient-parent dyads in acute treatment and n = 84 dyads in follow-up care completed measures on illness perceptions (Illness-Perceptions-Questionnaire for 12-18-year-old patients and parents or as age-adapted puppet interview for 4-11-year-old patients) and FoP (Fear-of-Progression-Questionnaire for 7-18-year-old patients and parents). Patients also completed the KINDL-R to measure HRQoL. Hierarchical multiple regression analyses were calculated. RESULTS In acute treatment, patient's perceptions of symptoms and cyclicity of their illness explained variation in their HRQoL in addition to sociodemographic and medical variables. In follow-up care, patient's FoP and parent's perception of consequences explained additional variation in patient's HRQoL. Overall, sociodemographic and medical variables explained less variation in HRQoL in follow-up care than in acute treatment. CONCLUSIONS Our results stress the importance of psychological factors for the well-being of paediatric cancer patients, particularly in follow-up care, where sociodemographic and medical variables play a lesser role. We recommend screening for illness perceptions and FoP during and after acute treatment to support patients and parents. Furthermore, standardized interventions focussed on changing maladaptive illness perceptions should be developed and evaluated. As parents' perceptions, thoughts, and feelings may also play an important role for the well-being of the patients, interventions should be family-focussed and include parents. Trial registration The study has been pre-registered at the German Clinical Trials Register (registered 30/06/2020; DRKS00022034) and at the Open Science Framework ( https://osf.io/3uwrx ).

Abstract
Objective Excessive fear of progression can affect the mental health, social function, and wellbeing of patients with chronic diseases. This study investigated the fear of progression (FoP) and the socio-demographic and clinical predictors among patients with type 2 diabetes mellitus (T2DM). Method The present study is a multi-center cross-sectional study. Inpatients with T2DM were recruited by a multi-stage convenience sampling method from the department of endocrinology in 5 tertiary hospitals in Southwest China. 459 T2DM patients were consecutively enrolled. Socio-demographic, clinical data, and answers to the fear of progression questionnaire (FoP-Q) were collected. Results 385 patients with complete data were eligible. The average score of FoP-Q-SF was 26.84 and 23.1% of patients reached the dysfunctional fear of progression criterion. The greatest fears were worrying about "disease progression," "the adverse reactions of medication," and "relying on strangers for activities of daily living." Health education (P < 0.001), age (P = 0.002), hypoglycemia history (P = 0.006), employment status (P = 0.025) and duration since being diagnosed with type 2 diabetes mellitus (P = 0.032) were the related factors of fear of progression. Conclusion Early assessment of the fear of progression was imperative to identify dysfunctional fear of progression in patients with type 2 diabetes mellitus. Meanwhile, the meaning of these predictors for strengthening healthcare professions education and patients self-management might help healthcare givers timely perform related interventions and help patients reduce their fear of progression thus actively cooperate with T2DM treatments.

Abstract
OBJECTIVE Fear of progression (FoP) is a common psychosocial problem among adult cancer patients, but data on parents of children undergoing cancer treatment are scarce. This study aimed to determine the prevalence of FoP in parents of children undergoing cancer treatment and explore the associated factors. METHODS Overall, 285 parents of children undergoing cancer treatment were recruited from three general hospitals in China. FoP in the parents was assessed using the Chinese version of the Fear of Progression Questionnaire-parent version (FoP-Q-SF/PR). Other questionnaires included the Self-Compassion Scale, Pittsburgh Sleep Quality Index, Posttraumatic Stress Disorder Checklist-Civilian Version, and items on socio-demographic and medical characteristics. Pearson correlation and multiple linear regression analysis were used to identify factors associated with FoP. RESULTS A total of 75.1% of the participants showed dysfunctional levels of FoP. The mean FoP-Q-SF/PR score was 39.98 (standard deviation=9.18). Parental FoP was significantly associated with a shorter time since diagnosis, lower levels of self-compassion, poor sleep quality, and severe posttraumatic stress symptoms (Adjusted R Squared=0.369, F=12.838, p<0.01). CONCLUSIONS FoP is a frequently reported problem among parents of children undergoing cancer treatment. In this cohort, parents of children with a shorter time since cancer diagnosis were at higher risk of suffering from FoP. Interventions to enhance self-compassion, improve sleep quality, and mitigate posttraumatic stress symptoms may help with the psychological adjustment and well-being of parents whose children are undergoing cancer treatment.

Abstract
OBJECTIVES Theoretical models suggest that anxiety, pain intensity, and pain catastrophizing are implicated in a cycle that leads to heightened fear of cancer recurrence (FCR). However, these relationships have not been empirically examined. The objective of this study was to examine the relationships between anxiety symptoms, pain intensity, pain catastrophizing, and FCR in childhood cancer survivors and their parents and to examine whether pain catastrophizing predicts increased FCR beyond anxiety symptoms and pain intensity. METHODS The participants were 54 survivors of various childhood cancers (Mage=13.1 y, range=8.4 to 17.9 y, 50% female) and their parents (94% mothers). Children reported on their pain intensity in the past 7 days. Children and parents separately completed measures of anxiety symptoms, pain catastrophizing, and FCR. RESULTS Higher anxiety symptoms were associated with increased pain intensity, pain catastrophizing, and FCR in childhood cancer survivors. Higher anxiety symptoms and pain catastrophizing, but not child pain intensity, were associated with FCR in parents. Hierarchical linear regression models revealed that pain catastrophizing explained unique variance in both parent (ΔR2=0.11, P<0.01) and child (ΔR2=0.07, P<0.05) FCR over and above the effects of their own anxiety symptoms and child pain. DISCUSSION The results of this study provides novel data on the association between pain and FCR and suggests that a catastrophic style of thinking about pain is more closely related to heightened FCR than one's anxiety symptoms or the sensory pain experience in both childhood cancer survivors and their parents. Pain catastrophizing may be a novel intervention target for survivors and parents struggling with fears of recurrence.

J Cancer Surviv 2021; 16:823-833. [PMID: 34302272 PMCID: PMC9300493 DOI: 10.1007/s11764-021-01076-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Accepted: 06/14/2021] [Indexed: 10/29/2022]
Abstract
PURPOSE Recent research demonstrated that fear of progression (FoP) is a major burden for adult cancer survivors. However, knowledge on FoP in parents of childhood cancer survivors is scarce. This study aimed to determine the proportion of parents who show dysfunctional levels of FoP, to investigate gender differences, and to examine factors associated with FoP in mothers and fathers. METHODS Five hundred sixteen parents of pediatric cancer survivors (aged 0-17 years at diagnosis of leukemia or central nervous system (CNS) tumor) were consecutively recruited after the end of intensive cancer treatment. We conducted hierarchical multiple regression analyses for mothers and fathers and integrated parent-, patient-, and family-related factors in the models. RESULTS Significantly more mothers (54%) than fathers (41%) suffered from dysfunctional levels of FoP. Maternal FoP was significantly associated with depression, a medical coping style, a child diagnosed with a CNS tumor in comparison to leukemia, and lower family functioning (adjusted R2 = .30, p < .001). Paternal FoP was significantly associated with a lower level of education, depression, a family coping style, a child diagnosed with a CNS tumor in comparison to leukemia, and fewer siblings (adjusted R2 = .48, p < .001). CONCLUSIONS FoP represents a great burden for parents of pediatric cancer survivors. We identified associated factors of parental FoP. Some of these factors can be targeted by health care professionals within psychosocial interventions and others can provide an indication for an increased risk for higher levels of FoP. IMPLICATIONS FOR CANCER SURVIVORS Psychosocial support targeting FoP in parents of childhood cancer survivors is highly indicated.

Abstract
BACKGROUND Impacts of the Covid-19 pandemic and its public health measures go beyond physical and mental health and incorporate wider well-being impacts in terms of what people are free to do or be. We explored the impacts of the Covid-19 lockdown and relevant vulnerabilities on capability well-being, mental health and social support in Austria. METHODS Adult Austrian residents (n = 560) provided responses to a cross-sectional online survey about their experiences during Covid-19 lockdown (15 March-15 April 2020). Instruments measuring capabilities (OxCAP-MH), depression and anxiety (HADS), social support (MSPSS) and mental well-being (WHO-5) were used in association with six pre-defined vulnerabilities using multivariable linear regression. RESULTS 31% of the participants reported low mental well-being and only 30% of those with a history of mental health treatment received treatment during lockdown. Past mental health treatment had a significant negative effect across all outcome measures with an associated capability well-being score reduction of - 6.54 (95%CI, - 9.26, - 3.82). Direct Covid-19 experience and being 'at risk' due to age and/or physical health conditions were also associated with significant capability deprivations. When adjusted for vulnerabilities, significant capability reductions were observed in association with increased levels of depression (- 1.77) and anxiety (- 1.50), and significantly higher capability levels (+ 3.75) were associated with higher levels of social support. Compared to the cohort average, individual capability impacts varied between - 9% for those reporting past mental health treatment and + 5% for those reporting one score higher on the social support scale. CONCLUSIONS Our study is the first to assess the capability limiting aspects of lockdown and relevant vulnerabilities alongside their impacts on mental health and social support. The negative capability well-being, mental health and social support impacts of the Covid-19 lockdown were strongest for people with a history of mental health treatment. Future public health policies concerning lockdowns should pay special attention to improve social support levels in order to increase public resilience.

Abstract
This study investigated the association of individual and dyadic coping strategies with fear of progression (FoP) in mothers and fathers of children with hematologic cancer. Parental couples (N = 44) whose children had been diagnosed with hematologic cancer were recruited at a university hospital and a rehabilitation clinic in Germany between 03/2017 and 08/2017. Data included parents' self-report on FoP (Fear of Progression Questionnaire-parent version, FoP-Q-SF/PR), individual coping (Coping Health Inventory for Parents, CHIP-D), and dyadic coping (Dyadic Coping Inventory, DCI). Statistical analyses were carried out for mothers and fathers individually as well as for parental couples using dyadic data analyses (e.g., actor-partner interdependence model, APIM). Individual and dyadic coping strategies were significantly correlated with FoP in mothers, but not in fathers. Fathers' evaluation of the couple's dyadic coping significantly predicted mothers' FoP. The more frequent use of familial integration (CHIP-D FAM) and maintaining social support (CHIP-D SUP) as well as a better evaluation of their partners' dyadic coping was significantly associated with lower FoP in mothers. Differences in individual and dyadic coping in parental couples were not associated with FoP. Individual and dyadic coping strategies should be addressed in the psychosocial care of mothers and fathers of children with hematologic cancer. Study results support the benefits of involving fathers in psychosocial interventions, for example, in couple-based interventions that acknowledge interpersonal effects of coping on FoP. Future research should further explore coping strategies applied by fathers of children with hematologic cancer for the regulation of FoP.

Abstract
OBJECTIVE Fear of progression (FoP), also referred to as fear of cancer recurrence, is gaining increasing interest in survivorship research as it constitutes a great burden for patients and relatives. However, only little is known about FoP in parents of childhood cancer survivors. The objective of this study was to investigate the impact of FoP on quality of life (QoL) in parental couples. METHODS We analyzed dyadic data of 197 couples parenting childhood cancer survivors (aged 0-17 years at diagnosis of leukemia or central nervous system tumor) after the end of intensive cancer treatment. The actor-partner interdependence model calculated by structural equation modelling was used to examine actor effects (effect of one's own FoP on one's own QoL) and partner effects (effect of one's own FoP on the partner's QoL). RESULTS Eighty-one percentage of the parents reported moderate or high FoP levels. Mothers reported higher FoP levels (p < .01) and lower overall QoL levels than fathers (p < .01). The results revealed a significantly positive intra-dyadic correlation between FoP of mothers and fathers of the same dyad (r = .431, p < .001). We found significantly negative actor effects for both mothers and fathers for the overall QoL (p < .001) as well as for several QoL subscales. No significant partner effects were found. CONCLUSIONS Most parents reported elevated levels of FoP. Our results show that FoP in parents of childhood cancer survivors is strongly negatively associated with QoL. Parental FoP should therefore be explored in future research and needs to be targeted by health care providers.

Abstract
OBJECTIVES To investigate experiences of parents of paediatric cancer survivors in cancer-related changes in the parents' daily life (work life, family life, partner relationship and social life) during and after intensive cancer treatment and to examine the reintegration process with its impeding and facilitating factors. DESIGN The design of this cross-sectional study involves a qualitative content analysis of semistructured interviews. SETTING Participants were consecutively recruited in clinical settings throughout Germany. PARTICIPANTS Forty-nine parents (59% female) of 31 cancer survivors (aged 0-17 at diagnosis of leukaemia or central nervous system tumour) were interviewed approximately 16-24 months after the end of intensive cancer treatment (eg, chemotherapy). RESULTS During treatment, more than 70% of parents reported difficulties reconciling paid work, household and family responsibilities and caring for the ill child. Couples spent little time with each other and approximately 25% reported dispute and burden. Many parents did not have enough energy for pursuing any hobbies during treatment. However, over the long term, being faced with the child's disease also led to strengthened relationships, new priorities, improved communication, increased mutual trust and greater appreciation for daily life. Supportive social networks (family/friends/employers), a strong partner relationship prior to the diagnosis and the use of psychosocial services (eg, family-oriented rehabilitation) had a positive impact. At the time of the interview, most families had adapted well. However, reintegration took time and some parents lacked the energy required to continue life as they did before the diagnosis. CONCLUSIONS Even though most parents successfully readjusted to a new 'normality', reintegrating into daily life after paediatric cancer treatment remains difficult. Professional psychosocial support could help families with the reintegration process. Lastly, clinical staff (eg, physicians, psychologists, social workers) should bear in mind that the burden of parents does not automatically end with the end of intensive cancer treatment.
