Purpose: To evaluate the effectiveness of two versions (personal or automated feedback) of a psychological Web-based self-help intervention targeting partners of cancer patients. The intervention was based on acceptance and commitment therapy (ACT) and self-compassion training. Participants' adherence and their satisfaction were also studied., Methods: Two hundred three partners of patients with heterogeneous entities of cancer were randomized into three conditions: personal feedback (PF) (n = 67), automated feedback (AF) (n = 70), or waiting list (WL) control (n = 66). Participants completed measures at baseline (T0) and post-intervention (T1; 3 months after baseline) to assess psychological distress (HADS; primary outcome), positive mental health, caregiver strain, general health (secondary outcomes), posttraumatic growth, resilience, self-compassion, psychological flexibility, sense of mastery, and relational communication style (process measures). Participants in the two experimental conditions also completed these measures at follow-up (T2; 6 months after baseline)., Results: There was no significant difference in change in psychological distress, positive mental health, caregiver strain and general health from T0 to T1 for either of the experimental conditions compared with the WL-condition. However, when compared to a WL-condition, the PF-condition was effective in increasing psychological flexibility (effect size d = 0.49) and resilience (d = 0.12) and decreasing overprotection (d = 0.25), and the AF-condition was effective in reducing overprotection (d = 0.36) and improving protective buffering (d = 0.36). At follow-up, the PF-condition was more effective than the AF-condition for improving mental health (d = 0.36), psychological flexibility (d = 0.60), mastery (d = 0.48), and protective buffering (d = 0.24). Participants positively appreciated the intervention and 69% participants were adherent., Conclusion: This study demonstrates that a Web-based intervention based on ACT and self-compassion training with automated or personal feedback does not seem to improve psychological distress; however, it may have the potential to support partners of cancer patients to cope with the difficult situation they are facing. The condition with personal feedback seemed to be more beneficial., (© 2021. The Author(s).)

Objectives: To gain an understanding of the perceptions of patients with incurable cancer regarding a new nurse-led self-management support intervention with an integrated eHealth application (Oncokompas) and its potential effectiveness., Sample & Setting: 36 patients receiving support in the home setting., Methods & Variables: A pre- and post-test mixed-methods design was used with a period of 12 weeks between the tests and qualitative interviews. Outcome measures were the perceived application of the intervention, patient satisfaction, patient activation, and quality of life., Results: 85% of patients were satisfied with the assessment of their needs and the advice received. They valued nurses' expertise and the assistance provided in their homes. Twenty-five percent of the patients used Oncokompas. However, no statistically significant changes in patient activation and quality of life were found., Implications for Nursing: This intervention can be used for encouraging self-management by patients with incurable cancer. Additional refinement and tailoring is desirable. Offering the intervention as early in the palliative phase as possible is recommended.

Purpose: Investigation of the feasibility of recruitment through nurses of patients with incurable cancer, and the feasibility (adoption, usage) and nurses' evaluation of a nurse-led self-management support intervention, integrated in continuity home visits and based on the 5 A's Behavior Change Model., Method: Questionnaire, registrations, evaluation forms, and interviews., Results: Recruitment was complicated; many patients were ineligible for participation, nurses appeared protective of their patients (gatekeeping), and recruitment during the first continuity home visit appeared to be a barrier as a lot of other issues had to be discussed. The adoption rate was 81%, meaning that 18 out of 22 nurses recruited were willing to use the intervention. The usage rate at the nurse level was 56%, meaning that 10 nurses applied the intervention in full (having applied all five A's) in at least one patient. Nurses used the intervention in full in 21 out of the 36 patients included, implying a usage rate at the patient level of 58%. Nurses' mean general satisfaction score for the intervention was 7.57 (range 0-10). Nurse were especially positive about the 5 A's model, and considered the continuity home visits to be an appropriate setting for the intervention., Conclusions: Timing of recruitment and gatekeeping complicated recruitment of patients through nurses. Although nurses were positive about the intervention, nurses often did not fully apply the intervention. To improve its usage, it is suggested that nurses should first be trained in using the 5 A's model., Competing Interests: Declarations of competing interest None declared., (Copyright © 2020 The Authors.

Background: Knowledge about the efficacy of behavioural intervention technologies that can be used by cancer survivors independently from a health-care provider is scarce. We aimed to assess the efficacy, reach, and usage of Oncokompas, a web-based eHealth application that supports survivors in self-management by monitoring health-related quality of life (HRQOL) and cancer-generic and tumour-specific symptoms and obtaining tailored feedback with a personalised overview of supportive care options., Methods: In this non-blinded, randomised, controlled trial, we recruited patients treated at 14 hospitals in the Netherlands for head and neck cancer, colorectal cancer, breast cancer, Hodgkin lymphoma, or non-Hodgkin lymphoma. Adult survivors (aged ≥18 years) were recruited through the Netherlands Cancer Registry (NCR) and invited by their treating physician through the Patient Reported Outcomes Following Initial Treatment and Long term Evaluation of Survivorship (PROFILES) registry. Participants were randomly assigned (1:1) by an independent researcher to the intervention group (access to Oncokompas) or control group (access to Oncokompas after 6 months), by use of block randomisation (block length of 68), stratified by tumour type. The primary outcome was patient activation (knowledge, skills, and confidence for self-management), assessed at baseline, post-intervention, and 3-month and 6-month follow-up. Linear mixed models (intention-to-treat) were used to assess group differences over time from baseline to 6-month follow-up. The trial is registered in the Netherlands Trial Register, NTR5774 and is completed., Findings: Between Oct 12, 2016, and May 24, 2018, 625 (21%) of 2953 survivors assessed for eligibility were recruited and randomly assigned to the intervention (320) or control group (305). Median follow-up was 6 months (IQR 6-6). Patient activation was not significantly different between intervention and control group over time (difference at 6-month follow-up 1·7 [95% CI -0·8-4·1], p=0·41)., Interpretation: Oncokompas did not improve the amount of knowledge, skills, and confidence for self-management in cancer survivors. This study contributes to the evidence for the development of tailored strategies for development and implementation of behavioural intervention technologies among cancer survivors., Funding: Dutch Cancer Society (KWF Kankerbestrijding)., (Copyright © 2020 Elsevier Ltd.

Purpose: The aim of this study was to investigate among female cancer patients their perceived social support from health care professionals (HCPs), family and friends, and public media, and their perspective on care concerning body changes., Methods: A study-specific questionnaire was completed by 235 female cancer patients. Descriptive statistics were used to describe social support and perspective on care. Logistic regression analyses were used to investigate the associations between social support and sociodemographic and clinical factors, psychosocial impact, and importance of appearance., Results: More than half of the patients received sufficient support from HCPs (54%) and family and friends (55%), and a third from the media (32%). Higher educated patients and those who found appearance not important during illness perceived lower support from HCPs. Patients without a partner, and those with a surgical treatment only, perceived lower support from family and friends. Patients who were older, higher educated, without a partner, and those who found appearance not important during illness perceived lower support from the media. In total, 15-50% of the patients received sufficient care for different domains of body changes. Patients expressed the highest need for psychological support (28%) and nutrition (28%)., Conclusions: Half of the female cancer patients reported to receive sufficient social support concerning body changes after cancer. Perceived support depended on age, education, relationship status, and treatment modality. The need for more care was moderate.

Purpose: Life review therapy combined with memory specificity training (LRT-MST) is effective in cancer patients in palliative care, but the effect size is moderate. The aim of this qualitative study was to obtain more in-depth knowledge on motivation to start with LRT-MST, experiences with LRT-MST, and perceived outcomes of LRT-MST., Methods: Semi-structured interviews were conducted with 20 cancer patients in palliative care who participated in a randomized controlled trial investigating the effect of LRT-MST. All interviews were digitally recorded and transcribed verbatim. Data were analyzed by means of thematic analysis independently by two coders and coded into key issues and themes., Results: Patients started LRT-MST for intrinsic (e.g., potential benefit for personal well-being) and extrinsic reasons (e.g., potential benefit for future patients). Patients indicated mainly positive experiences with the intervention. They appreciated sharing their memories and regaining memories with a specific focus on retrieving positive memories. Some disliked the fact that negative memories could not be addressed. Most patients perceived positive outcomes of the intervention belonging to the overarching themes "ego-integrity" and "psychological well-being" in the here and now, as well as in the nearby future (including end-of-life)., Conclusions: LRT-MST is of added value as a psychological intervention in palliative care. This study provided in-depth insight into reasons to start the intervention, and the experiences and outcomes, which are important to further tailor LRT-MST and for development or improvement of other psychological interventions targeting cancer patients in palliative care.

Purpose: A web-based self-management application "Oncokompas" was developed to monitor health-related quality of life and to support cancer survivors in finding and obtaining optimal supportive care. Access to this application is provided via a healthcare professional (HCP). The aim of this study was to explore the adoption and implementation of Oncokompas in routine clinical practice and to obtain insights in potentially relevant determinants of implementation., Methods: A pilot study was carried out among 65 hospitals throughout The Netherlands. HCPs filled out a questionnaire on the implementation of Oncokompas in their organization, consisting of study specific items and items based on the Measurement Instrument for Determinants of Innovations (MIDI). The MIDI comprises 29 determinants in four domains that predict the use of innovations: the innovation itself (Oncokompas), the user (HCP), the organization (hospital), and socio-political context., Results: In total, 20/65 eligible hospitals agreed to implement Oncokompas (adoption rate 31%). In these 20 adopting hospitals, the majority of the responding HCPs (72/205) in this study (44/61) indicated their patients were offered access to Oncokompas (implementation rate 72%). Comparing those HCPs who did and did not implement Oncokompas, the groups differed significantly on innovation-related (procedural clarity, complexity) and user-related determinants (importance of outcome expectations, professional obligation, social support, and self-efficacy)., Conclusions: During this 1-year study, nationwide adoption rate of Oncokompas was at 31%, and subsequent implementation rate was at 72%. The results of this study contribute to further optimize interventions and strategies to adopt and implement (online) self-management applications in cancer care.

Objectives: To explore how nurses perceive their self-efficacy and performance in supporting self-management among patients with incurable cancer, and whether these perceptions differ between community and hospital nurses., Sample & Setting: 222 hospital nurses (n = 94) and community nurses (n = 128) working with adult patients with incurable cancer., Methods & Variables: An online survey included the Self-Efficacy and Performance Into Self-Management Support instrument. Possible differences in age, gender, work setting, and additional training in oncology between groups were explored., Results: Nurses felt confident about their self-efficacy, particularly in assessing patients' knowledge and beliefs and in advising about their disease and health status. Nurses felt less confident in their performance, particularly in the use of technology (arranging follow-up care), but also in agreeing on collaborative goals and assisting patients in achieving these goals. Compared to hospital nurses, community nurses reported significantly higher scores on self-efficacy and performance., Implications for Nursing: More effort is needed to increase nurses' confidence in providing self-management support, with a focus on arranging follow-up care with the use of technology and on collaborating with patients in setting and achieving goals.

Background: Meaning-centered group psychotherapy for cancer survivors (MCGP-CS) improves meaning, psychological well-being, and mental adjustment to cancer and reduces psychological distress. This randomized controlled trial was conducted to investigate the cost-utility of MCGP-CS compared with supportive group psychotherapy (SGP) and care-as-usual (CAU)., Methods: In total, 170 patients were randomized to MCGP-CS, SGP, or CAU. Intervention costs, direct medical and nonmedical costs, productivity losses, and health-related quality of life were measured until 6 months follow-up, using the TIC-P, PRODISQ, data from the hospital information system, and the EQ-5D. The cost-utility was calculated by comparing mean cumulative costs and quality-adjusted life years (QALYs)., Results: Mean total costs ranged from €4492 (MCGP-CS) to €5304 (CAU). Mean QALYs ranged .507 (CAU) to .540 (MCGP-CS). MCGP-CS had a probability of 74% to be both less costly and more effective than CAU, and 49% compared with SGP. Sensitivity analyses showed these findings are robust. If society is willing to pay €0 for one gained QALY, MCGP-CS has a 78% probability of being cost-effective compared with CAU. This increases to 85% and 92% at willingness-to-pay thresholds of €10 000 and €30 000, which are commonly accepted thresholds., Conclusions: MCGP-CS is highly likely a cost-effective intervention, meaning that there is a positive balance between the costs and gains of MCGP-CS, in comparison with SGP and CAU., (Copyright © 2018 John Wiley & Sons, Ltd.)

Introduction: Body image is acknowledged as an important aspect of health-related quality of life in cancer patients. The Body Image Scale (BIS) is a patient-reported outcome measure (PROM) to evaluate body image in cancer patients. The aim of this study was to systematically review measurement properties of the BIS among cancer patients., Methods: A search in Embase, MEDLINE, PsycINFO, and Web of Science was performed to identify studies that investigated measurement properties of the BIS (Prospero ID 42017057237). Study quality was assessed (excellent, good, fair, poor), and data were extracted and analyzed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology on structural validity, internal consistency, reliability, measurement error, hypothesis testing for construct validity, and responsiveness. Evidence was categorized into sufficient, insufficient, inconsistent, or indeterminate., Results: Nine studies were included. Evidence was sufficient for structural validity (one factor solution), internal consistency (α = 0.86-0.96), and reliability (r > 0.70); indeterminate for measurement error (information on minimal important change lacked) and responsiveness (increasing body image disturbance in only one study); and inconsistent for hypothesis testing (conflicting results). Quality of the evidence was moderate to low. No studies reported on cross-cultural validity., Conclusion: The BIS is a PROM with good structural validity, internal consistency, and test-retest reliability, but good quality studies on the other measurement properties are needed to optimize evidence. It is recommended to include a wider variety of cancer diagnoses and treatment modalities in these future studies.

This study examined partners of cancer patients intention to use a web-based psychological intervention, their preferences regarding its preconditions, functionalities and topics, and factors related to their intention. One hundred and sixty-eight partners completed a questionnaire about these aspects. Forty-eight percent of the partners would (maybe) make use of a web-based intervention. Partners who intended to participate were significantly younger, used the Internet more often, and perceived more caregiver strain. Most partners preferred an intervention that takes less than 1 hour/week, lasts five weeks or more, and contains information and peer support. Half of the partners would like to receive online guidance.

Background: Self-management by patients and informal caregivers confronted with advanced cancer is not self-evident. Therefore they might need self-management support from nurses. This article reports on nurses' perspectives on self-management support for people confronted with advanced cancer, and nurses' experiences with eHealth in this context., Methods: Six online focus groups were organized, with a total of 45 Dutch nurses with different educational levels and working in different care settings. Nurses were asked how they support patients and informal caregivers facing advanced cancer in managing physical and psychosocial problems in their daily life. Questions were also asked regarding the nurses' experiences with eHealth. Transcripts of the online focus group discussions were analyzed qualitatively following the principles of thematic analysis. The main themes derived from the analyses were ordered according to the elements in the 5 A's Behavior Change Model., Results: Within the scope of self-management support, nurses reported that they discuss the background, personal situation, wishes, and needs of advanced cancer patients ('Assess' in the 5 A's model), and they provide information about cancer and specifically the advanced type ('Advise'). However, nurses hardly give any advice on how patients can manage physical and psychological problems themselves and/or pay any attention to collaborative goal-setting ('Agree'). Neither do they explain how follow-up can be arranged ('Arrange'). In addition, they do not appear to pay much attention to self-management support for informal caregivers. Nurses' attitudes towards eHealth within the scope of self-management support are positive. They see many advantages, such as allowing advanced cancer patients to stay in charge of their own care and lives. However, nurses also explicitly stressed that eHealth can never be a substitute for personal contact between nurses and patients., Conclusions: Nurses value self-management support and eHealth for advanced cancer patients and their informal caregivers. However, they seem to disregard important elements in the support of self-management, such as providing practical advice, collaborative goal-setting, and arrangement of follow-up. We recommend further promoting and clarifying the essence and importance of self-management support, including self-management support for informal caregivers.

Background: Cancer survivors have to deal with a wide range of physical symptoms, psychological, social and existential concerns, and lifestyle issues related to cancer and its treatment. Therefore, it is essential that they have access to optimal supportive care services. The eHealth self-management application Oncokompas was developed to support cancer survivors with where they need to turn to for advice and guidance, as well as to increase their knowledge on the availability of optimal support. A randomised controlled trial will be conducted to assess the efficacy, cost-utility and reach of Oncokompas as an eHealth self-management application compared with care as usual among cancer survivors., Methods/design: Adult cancer survivors diagnosed with breast, colorectal or head and neck cancer or lymphoma who are at 3 months to 5 years since curative treatment will be included. In total, 544 cancer survivors will be randomly assigned to the intervention group or a wait-list control group. The primary outcome measure is patient activation. Secondary outcome measures include self-efficacy, personal control, perceived patient-physician interaction, need for supportive care, mental adjustment to cancer and health-related quality of life. Furthermore, cost-utility outcomes will be assessed. Reach is defined as the percentage of cancer survivors who get access to Oncokompas within the context of this trial. Questionnaires will be administered at baseline, post-intervention and at 3- and 6-month follow-up., Discussion: In this study, we will evaluate the efficacy and cost-utility of Oncokompas among cancer survivors, as well as the reach of Oncokompas. These are essential first steps in the translation of research into practice and contribute to sustainable adoption, implementation and maintenance of an evidence-based Oncokompas., Trial Registration: Netherlands Trial Register identifier: NTR5774 . Registered on 8 March 2016.

Background: eHealth can be defined as information provision about illness or health care and/or support for patients and/or informal caregivers, using the computer or related technologies. eHealth interventions are increasingly being used in cancer care, e.g. to support patients and informal caregivers in managing symptoms and problems in daily life., Objectives: To synthesize evidence from systematic reviews on the effects of eHealth for cancer patients or their informal caregivers., Materials and Methods: A systematic meta-review, in the sense of a systematic review of reviews, was conducted. Searches were performed in PubMed, Embase, CINAHL, PsycINFO, and the Cochrane Library. All steps in the review process were either performed by two reviewers independently or checked by a second reviewer. Disagreements were resolved by consensus., Results: Ten systematic reviews were included. All reviews focused on the effects of eHealth for patients and none on effects for informal caregivers. Except for one review of high methodological quality, all reviews were of moderate methodological quality. Evidence was found for effects on perceived support, knowledge levels, and information competence of cancer patients. Indications of evidence were found for health status and healthcare participation. Findings were inconsistent for outcomes related to decision-making, psychological wellbeing, depression and anxiety, and quality of life. No evidence was found for effects on physical and functional wellbeing., Conclusion: There is evidence for positive effects of eHealth on perceived support, knowledge, and information competence of cancer patients. For effects on other outcomes in cancer patients, findings are mainly inconsistent or lacking. This meta-review did not find relevant reviews focusing on or including the effects of eHealth on informal caregivers, which seems a rather unexplored area., (Copyright © 2015 Elsevier Ireland Ltd.

Purpose: The aim of this study is to compare the generic and ostomy-specific quality of life (QoL) between cancer and non-cancer ostomy patients using a mixed-method design., Methods: All patients with an ostomy participating in the Stomapanel of the Dutch Ostomy Association were asked to complete a generic (RAND-36) and ostomy-specific (Stoma-QoL) QoL questionnaire. In addition, open-ended questions on symptoms, restrictions or adaptations influencing daily life were included. The generic and ostomy-specific QoL between cancer and non-cancer ostomy patients were compared using linear regression analyses. Qualitative responses were analysed using content analysis., Results: In total, 668 patients were included: 379 cancer patients (80 % colorectal, 17 % bladder and 3 % other) and 289 non-cancer patients (38 % colitis ulcerosa, 22 % Crohn's disease and 40 % other) with a colostomy (55 %), ileostomy (31 %) and/or urostomy (16 %). Adjusted for gender, age, type of ostomy and time elapsed since ostomy surgery, cancer ostomy patients scored higher (better) on Stoma-QoL (β = 2.1) and all RAND-36 domains (9.1 < β ≤ 19.5) except on mental health compared to non-cancer ostomy patients. Of the 33 themes coded for in the content analysis, fatigue or sleeplessness, leakages, pain, bladder or bowel complaints, physical functioning or activity, travelling or being away from home, other daily activities (including work), clothing and diet were among the 10 most frequently reported themes, although ranking differed between both patient groups. Besides, cancer ostomy patients frequently reported on the impact on (engaging in a) relationship or sexual intimacy and non-cancer ostomy patients frequently reported to be relieved of symptoms and restrictions in daily life., Conclusions: Cancer patients reported better generic and ostomy-specific QoL than non-cancer ostomy patients. In both cancer and non-cancer ostomy patients, fatigue or sleeplessness, leakages, pain, bladder or bowel complaints, physical functioning or activity, travelling or being away from home, other daily activities (including work), clothing and diet were among the 10 most common reported themes influencing daily life. However, the ranking of these 10 most common themes was different in both patient groups.

Purpose: The aim of this study was to explore the perceived need for supportive care including healthy lifestyle programs among cancer survivors, their attitude towards self-management and eHealth, and its association with several sociodemographic and clinical variables and quality of life., Methods: A questionnaire on the perceived need for supportive care and attitude towards self-management and eHealth was completed by 212 cancer survivors from an online panel., Results: Highest needs were reported regarding physical care (66 %), followed by healthy lifestyle programs (54 %), social care (43 %), psychological care (38 %), and life question-related programs (24 %). In general, cancer survivors had a positive attitude towards self-management and eHealth. Supportive care needs were associated with male gender, lower age, treatment with chemotherapy or (chemo)radiation (versus surgery alone), hematological cancer (versus skin cancer, breast cancer, and other types of cancer), and lower quality of life. A positive attitude towards self-management was associated with lower age. A more positive attitude towards eHealth was associated with lower age, higher education, higher income, currently being under treatment (versus treatment in the last year), treatment with chemotherapy or (chemo)radiation (versus surgery alone), prostate and testicular cancer (versus hematological, skin, gynecological, and breast cancer and other types of cancer), and lower quality of life., Conclusions: The perceived need for supportive care including healthy lifestyle programs was high, and in general, cancer survivors had a positive attitude towards self-management and eHealth. Need and attitude were associated with sociodemographic and clinical variables and quality of life. Therefore, a tailored approach seems to be warranted to improve and innovate supportive care targeting cancer survivors.

Background: Meaning-focused coping may be at the core of adequate adjustment to life after cancer. Cancer survivors who experience their life as meaningful are better adjusted, have better quality of life and psychological functioning. Meaning-Centered Group Psychotherapy for Cancer Survivors (MCGP-CS) was designed to help patients to sustain or enhance a sense of meaning and purpose in their lives. The aim of the proposed study is to evaluate the effectiveness and cost-effectiveness of MCGP-CS., Methods/design: Survivors diagnosed with cancer in the last 5 years and treated with curative intent, are recruited via several hospitals in the Netherlands. After screening, 168 survivors are randomly assigned to one of the three study arms: 1. Meaning-Centered Group Psychotherapy (MCGP-CS) 2. Supportive group psychotherapy (SGP) 3. Care as usual (CAU). Baseline assessment takes place before randomisation, with follow up assessments post-intervention and at 3, 6 and 12 months follow-up. Primary outcome is meaning making (PMP, PTGI, SPWB). Secondary outcome measures address quality of life (EORTC-30), anxiety and depression (HADS), hopelessness (BHS), optimism (LOT-R), adjustment to cancer (MAC), and costs (TIC-P, EQ-5D, PRODISQ)., Discussion: Meaning-focused coping is key to adjustment to life after cancer, however, there is a lack of evidence based psychological interventions in this area. Many cancer survivors experience feelings of loneliness and alienation, and have a need for peer support, therefore a group method in particular, can be beneficial for sustaining or enhancing a sense of meaning. If this MCGP-CS is effective for cancer survivors, it can be implemented in the practice of psycho-oncology care., Trial Registration: Netherlands Trial Register, NTR3571.

Background: Confrontation with a life-threatening disease like cancer can evoke existential distress, which can trigger a search for meaning in people after having survived this disease., Methods: In an effort to gain more insight in the meaning making process, we conducted four focus groups with 23 cancer survivors on this topic. Participants responded to questions about experienced meaning making, perceived changes in meaning making after cancer and the perceived need for help in this area., Results: Most frequently mentioned meaning making themes were relationships and experiences. We found that, in general, cancer survivors experienced enhanced meaning after cancer through relationships, experiences, resilience, goal-orientation and leaving a legacy. Some participants, however, also said to have (also) experienced a loss of meaning in their lives through experiences, social roles, relationships and uncertainties about the future., Conclusions: The results indicated that there is a group of cancer survivors that has succeeded in meaning making efforts, and experienced sometimes even more meaning in life than before diagnosis, while there is also a considerable group of survivors that struggled with meaning making and has an unmet need for help with that. The results of this study contribute to develop a meaning centered intervention for cancer survivors.
