Development of the Psychosocial Distress Questionnaire-Breast Cancer (PDQ-BC): a breast cancer-specific screening instrument for psychosocial problems

CBT-based Online Self-help Training to Reduce Fear and Distress After Cancer (CAREST Randomized Trial): 24 Months Follow-up Using Latent Growth Models and Latent Class Analysis

BACKGROUND

Psychological distress (PD) and fear of cancer recurrence (FCR) are common consequences of surviving cancer. Online self-help training could help many cancer survivors deal with PD and FCR at low costs.

PURPOSE

To evaluate the long-term effectiveness of the CAncer REcurrence Self-help Training (CAREST trial) to reduce PD and FCR. Moreover, to evaluate the relation between FCR and PD across time and identify subgroups representing different change trajectories in FCR over time and their predictors.

METHODS

This multicenter randomized controlled trial included 262 female breast cancer survivors, assigned to online self-help training or care as usual. Participants completed questionnaires at baseline and four times during the 24-month follow-up. The primary outcomes were PD and FCR (Fear of Cancer Recurrence Inventory). Latent growth curve modeling (LGCM) and repeated measures latent class analysis (RMLCA) were performed, both according to the intention-to-treat principle.

RESULTS

LGCM showed no differences between the average latent slope in both groups for both PD and FCR. The correlation between FCR and PD at baseline was moderate for the intervention group and strong for the CAU group and did not significantly decrease over time in both groups. RMLCA revealed five latent classes and several predictors of class membership.

CONCLUSIONS

We did not find a long-term effect of the CBT-based online self-help training in reducing PD or FCR, nor in their relation. Therefore, we recommend adding professional support to online interventions for FCR. Information about FCR classes and predictors may contribute to improvement of FCR interventions.

Alterações musculoesquelética, cardiorrespiratória, antropométrica e sensorial após cirurgia de câncer de mama

Resumo Introdução: O câncer de mama é a segunda neoplasia maligna mais encontrada entre as mulheres, sendo a intervenção cirúrgica um dos tratamentos preconizados, o que pode acarretar sequelas físicas e sensoriais importantes. Objetivo: Analisar as funções musculoes-queléticas, cardiorrespiratórias, antropométricas e sensoriais de mulheres submetidas ao procedimento cirúrgico para neoplasia mamária. Métodos: Estudo observacional e transversal com mulheres que realizaram procedimento cirúrgico para ressecção de neoplasia mamária assistidas no interior paulista, Jaú/SP. Foram realizadas três avaliações: pré-cirurgia (AV1), um dia (AV2) e 15 dias após a cirurgia (AV3). Foram coletadas informações sociodemográficas e ginecológicas e realizadas avaliações antropométrica, cardiovascular, sensibilidade dérmica, amplitude de movimento (ADM) dos membros superiores, saturação periférica de oxigênio (SpO2), força muscular inspiratória (PImax), pico de fluxo expiratório (PFE) e mobilidade toracoabdominal. Os dados foram avaliados pelo teste estatístico ANOVA de medidas repetidas e Wilcoxon com correção de Bonferroni (p < 0,05). Resultados: Dezoito mulheres, de 57,44 ± 9,35 anos, tiveram o lado esquerdo mais acometido (61,1%) e a linfonodectomia foi realizada em 50% dos casos. Houve diferenças nas variáveis pressão arterial sistólica e diastólica, PFE e SpO2, índice de amplitude axilar (AV1>AV2), PImax (AV3>AV2), perimetria (AV2>AV3), ADM em todos os eixos de movimento do ombro e em flexão de punho (AV2<AV1) e alteração de sensibilidade próxima à cicatriz (AV3>AV2 e AV1). Conclusão: A cirurgia para exerese de neoplasia mamária acarretou alterações principalmente hemodinâmicas e respiratórias, sobremaneira no primeiro dia após a cirurgia, retornando aos valores basais aproxi-madamente 15 dias após o procedimento.

Musculoskeletal, cardiorespiratory, anthropometric and sensorial changes following breast cancer surgery

Abstract Introduction: Breast cancer is the second most common malignant neoplasm in women. Surgical intervention is one of the recommended treatments, which can lead to significant physical and sensorial sequelae. Objective: To analyze the musculoskeletal, cardiorespiratory, anthropometric and sensorial functions of women who underwent breast cancer surgery. Methods: An observational, cross-sectional study with women who underwent surgical resection of breast tumors at Amaral Carvalho, a reference hospital in the countryside of the São Paulo State, Jaú/SP, Brazil. Three assessments were obtained: pre-surgery (Ass1), one day after the surgery (Ass2) and 15 days after surgery (Ass3). Sociodemographic and gynecological data were collected, and anthropometric, cardiovascular, dermal sensitivity, range of motion (ROM) of the upper limbs, peripheral oxygen saturation (SpO2), inspiratory muscle strength (PImax), peak expiratory flow (PEF) and thoraco-abdominal mobility assessments were performed. Data were evaluated by repeated measures ANOVA and Wilcoxon statistical test with a Bonferroni correction (p < 0.05). Results: Eighteen women, with a mean age of 57.44 ± 9.35 years, mainly with the left side affected (61.1%) and lymphadenectomy performed in 50% of the cases. Differences were found in systolic and diastolic blood pressure, PEF and SpO2, axillary ROM index (Ass1>Ass2), PImax (Ass3>Ass2), perimetry (Ass2>Ass3), ROM in all axes of shoulder motion and wrist flexion (Ass2<Ass1), and sensitivity alteration close to the surgical wound (Ass3>Ass2 and Ass1). Conclusion: The surgery for breast cancer excision resulted in hemodynamic and respiratory changes, especially on the first day after the procedure, returning to baseline values approximately 15 days later.

Psychometric evaluation of a questionnaire for measuring factors related to mental health of women in an earthquake

The current study was performed with the aim of the psychometric evaluation of a questionnaire for measuring factors related to women's mental health in an earthquake. This descriptive instrumental study was carried out on a population of 378 women with an earthquake experience in Kerman Province, Iran, in 2017-2018. The formal validity, content validity, criterion validity, factor analysis, and reliability of the questionnaire were measured using Cronbach's alpha coefficient. Moreover, descriptive statistics and Pearson's correlation coefficient were used to report data. In the content validity stage, 34out of 85 items of the questionnaire were eliminated. In the exploratory factor analysis (EFA) stage, 2 items out of the remaining 51 items were removed due to weak factor loading and 49 items were defined in 6 factors. The convergent and divergent validities of the questionnaire were confirmed in relation to the General Health Questionnaire (GHQ) (r = -0.23; P = .030) and World Health Organization Quality of Life-BREF ‎(WHOQOL-BREF) (r = 0.32;P = .001). Using Cronbach's alpha coefficient, the reliability of the questionnaire‎was obtained to be 0.91. The reliability and validity of the study questionnaire were at an appropriate level, and thus, it can be used to perform extensive surveys among women who have ‎experienced earthquake.

No effect of CBT-based online self-help training to reduce fear of cancer recurrence: First results of the CAREST multicenter randomized controlled trial

OBJECTIVE

Fear of cancer recurrence (FCR) is a common consequence of surviving cancer; therefore, easily accessible self-help training could help many cancer survivors deal with FCR at low costs. The CAncer REcurrence Self-help Training (CAREST) trial evaluates the effectiveness of an online-tailored self-help training on the basis of evidence-based cognitive behavioral therapy principles in breast cancer survivors. Also, possible predictors for benefitting from the online self-help training were examined.

METHODS

This multicenter randomized controlled trial included 262 female breast cancer survivors, randomly assigned to either online self-help training (n = 130) or care as usual (CAU; n = 132). Participants completed questionnaires at baseline (T0), 3 months (T1; after intervention), and 9 months (T2). The primary outcome was FCR (Fear of Cancer Recurrence Inventory Severity subscale). Both effectiveness and predictors were analyzed with latent growth curve modeling (LGCM) according to the intention-to-treat principle.

RESULTS

LGCM showed no differences between the average latent slope in both groups (χ² ₁  = .23, P = .63), suggesting that the treatments did not differ in their change in FCR over time. Moreover, no differences were found in the effects of the predictors on the latent slope in both groups (χ² ₁  = .12, P = .73), suggesting that no significant predictors were found for the effect of the intervention on FCR.

CONCLUSION

There was no effect of the CBT-based online self-help training "Less fear after cancer" in the current study. Therefore, we recommend adding professional support to online interventions for FCR.

Psychometric properties of the psychosocial screening instrument for physical trauma patients (PSIT)

Background

Early detection of psychosocial problems post-injury may prevent them from becoming chronic. Currently, there is no psychosocial screening instrument that can be used in patients surviving a physical trauma or injury. Therefore, we recently developed a psychosocial screening instrument for adult physical trauma patients, the PSIT. The aim of this study was to finalize and psychometrically examine the PSIT.

Methods

All adult (≥ 18 years) trauma patients admitted to a Dutch level I trauma center from October 2016 through September 2017 without severe cognitive disorders (n = 1448) received the PSIT, Impact of Events Scale-Revised (IES-R), Patient Health Questionnaire-9 (PHQ-9), Rosenberg Self-Esteem Scale (RSES), State-Trait Anxiety Inventory-State (STAI-S), and the World Health Organization Quality of Life-Abbreviated version (WHOQOL-Bref). After 2 weeks, a subgroup of responding participants received the PSIT a second time. The internal structure (principal components analysis, PCA; and confirmatory factor analysis, CFA), internal consistency (Cronbach’s alpha, α), test-retest reliability (Intraclass Correlation Coefficient, ICC), construct validity (Spearman’s rho correlations), diagnostic accuracy (Area Under the Curve, AUC), and potential cut-off values (sensitivity and specificity) were examined.

Results

A total of 364 (25.1%) patients participated, of whom 128 completed the PSIT again after 19.5 ± 6.8 days. Test-retest reliability was good (ICC = 0.86). Based on PCA, five items were removed because of cross-loadings ≥ 0.3. Three subscales were identified: (1) Negative affect (7 items; α = 0.91; AUC = 0.92); (2) Anxiety and Post-Traumatic Stress Symptoms (4 items; α = 0.77; AUC = 0.88); and (3) Social and self-image (4 items; α = 0.79; AUC = 0.92). CFA supported this structure (comparative fit index = 0.96; root mean square error of approximation = 0.06; standardized rood mean square residual = 0.04). Four of the five a priori formulated hypotheses regarding construct validity were confirmed. The following cut-off values represent maximum sensitivity and specificity: 7 on subscale 1 (89.6% and 83.4%), 3 on subscale 2 (94.4% and 90.3%), and 4 on subscale 3 (85.7% and 90.7%).

Conclusion

The final PSIT has good psychometric properties in adult trauma patients.

Psychosocial screening for patients with prostate cancer: The development and validation of the psychosocial distress questionnaire-prostate cancer

We describe the psychosocial distress questionnaire-prostate cancer (PDQ-PC), a psychosocial screening list developed and validated specifically for prostate cancer patients. An existing screening list, the psychosocial distress questionnaire-breast cancer (PDQ-BC), was used as a starting point. Two focus groups were then implemented to investigate which items of the PDQ-BC were relevant for the PDQ-PC and which new items were needed. Validity and reliability of the questionnaire were assessed on 278 prostate cancer patients. Factor analysis showed that the 36-item PDQ-PC comprises eight subscales, for which the internal consistency ranged from α = 0.48-0.88. Moreover, moderate to high convergent validity was found.

Study protocol of the CAREST-trial: a randomised controlled trial on the (cost-) effectiveness of a CBT-based online self-help training for fear of cancer recurrence in women with curatively treated breast cancer

Background

One of the most prevalent long-term consequences of surviving breast cancer is fear of cancer recurrence (FCR), which is associated with higher (mental) healthcare costs and lower surveillance rates. The majority of breast cancer survivors report a need for professional help in dealing with FCR. An easy-accessible and cost-effective evidence‐based psychological intervention for reducing FCR is lacking. In the current study an online self-help training to reduce FCR will be evaluated. In addition, the secondary aim of this study is to identify factors that predict whether women can benefit from the online self-help training or not.

Methods/Design

A multi-centre, parallel-groups, randomised controlled trial will be conducted to evaluate the (cost-) effectiveness of the CAREST-trial. A sample of 454 women with curatively treated breast cancer will be recruited from 8 hospitals in the Netherlands. Participants will be randomised to the intervention or usual care group (1:1). Self-report measures will be completed at baseline, 3 (post-intervention), 9, and 24 months. Primary outcome is FCR severity; secondary outcomes are healthcare costs, health status, and psychological distress. The online tailored self-help training “Less fear after cancer” is based on cognitive behavioural therapy and consists of 2 basic modules (psycho-education; basic principles of cognitive behavioural therapy) and 4 optional modules (rumination; action; relaxation; reassurance) to choose from. Each module consists of an informative part (texts, videos, audio files) and a practical part (exercises). For every patient, the intervention will be available for three months. Personal online support by an e-mail coach is available.

Discussion

Online self-help training may be an easy-accessible and cost-effective treatment to reduce the impact of FCR at an early stage in a large group of breast cancer survivors. A strength is the 24 months follow-up period in the health economic evaluation. The results of the study will provide information on the possible strengths and benefits of online self-help training for FCR in breast cancer survivors.

Trial registration

This study is registered at the Netherlands Trial Register (NTR4119, date registered: August 15, 2013).

Women with breast cancer: self-reported distress in early survivorship

PURPOSE/OBJECTIVES

To identify and compare levels of distress and sources of problems among patients with breast cancer in early survivorship.

DESIGN

Descriptive, cross-sectional.

SETTING

A National Cancer Institute-designated comprehensive cancer center.

SAMPLE

100 breast cancer survivors were selected to represent four time points in the cancer trajectory.

METHODS

Distress was self-reported using the Distress Thermometer and its 38-item problem list. Analysis of variance and chi-square analyses were performed as appropriate.

MAIN RESEARCH VARIABLES

Distress scores, problem reports, and time groups.

FINDINGS

Participants scored in range of the cutoff of more than 4 (range = 4.1-5.1) from treatment through three months post-treatment. At six months post-treatment, distress levels were significantly lower. Significant differences were found between groups on the total problem list score (p = 0.007) and emotional (p = 0.01) and physical subscale scores (p = 0.003).

CONCLUSIONS

Comparison of groups at different points in the cancer trajectory found similar elevated levels from diagnosis through three months. Distress remained elevated in early survivorship but significantly decreased at six months post-treatment.

IMPLICATIONS FOR NURSING

Interventions to reduce or prevent distress may improve outcomes in early survivorship.

Cancer or no cancer: the influence of trait anxiety and diagnosis on quality of life with breast cancer and benign disease: a prospective, longitudinal study

BACKGROUND

High trait anxiety (HTA) causes an impaired quality of life (QOL) and fatigue in women with breast cancer (BC) and benign breast disease (BBD). We examined whether the lowered QOL was determined solely by the personality characteristic HTA or by the combination of personality and diagnosis.

METHODS

In a prospective longitudinal study, women with BC (n = 152), BBD (n = 205), or gallstone disease (GD) before laparoscopic cholecystectomy (n = 128) were included. Questionnaires concerning trait anxiety (baseline), fatigue, and QOL were completed at baseline and at 6 months. Multivariate linear regression analysis was performed to analyze the predictors for QOL at 6 months.

RESULTS

At 6 months QOL scores were increased in the GD group, especially in women without HTA. For women without HTA, in the BBD group the scores for fatigue and physical QOL had improved at 6 months, whereas in the BC group physical QOL and fatigue was impaired. Women with HTA scored unfavorably on fatigue and QOL. HTA was the most important factor influencing QOL.

CONCLUSIONS

The course of QOL and fatigue during follow-up were significantly different for each diagnosis. Particularly HTA had a negative impact on QOL and fatigue. Especially the combination HTA and BC caused impaired QOL and fatigue. We recommend identifying women with BC and HTA and offer them a tailor-made follow-up protocol.

Predicting quality of life after breast cancer surgery using ANN-based models: performance comparison with MR

PURPOSE

The goal was to develop models for predicting long-term quality of life (QOL) after breast cancer surgery.

METHODS

Data were obtained from 203 breast cancer patients who completed the SF-36 health survey before and 2 years after surgery. Two of the models used to predict QOL after surgery were artificial neural networks (ANNs), which included one multilayer perceptron (MLP) network and one radial basis function (RBF) network. The third model was a multiple regression (MR) model. The criteria for evaluating the accuracy of the system models were mean square error (MSE) and mean absolute percentage error (MAPE).

RESULTS

Compared to the MR model, the ANN-based models generally had smaller MSE values and smaller MAPE values in the test data set. One exception was the second year MSE for the test value. Most MAPE values for the ANN models ranged from 10 to 20 %. The one exception was the 6-month physical component summary score (PCS), which ranged from 23.19 to 26.86 %. Comparison of criteria for evaluating system performance showed that the ANN-based systems outperformed the MR system in terms of prediction accuracy. In both the MLP and RBF networks, surgical procedure type was the most sensitive parameter affecting PCS, and preoperative functional status was the most sensitive parameter affecting mental component summary score.

CONCLUSION

The three systems can be combined to obtain a conservative prediction, and a combined approach is a potential supplemental tool for predicting long-term QOL after surgical treatment for breast cancer.

RELEVANCE

Patients should also be advised that their postoperative QOL might depend not only on the success of their operations but also on their preoperative functional status.

Chemotherapy and cognitive complaints in women with breast cancer

BACKGROUND

Results of existing studies are inconclusive concerning the relationship between chemotherapy and subjective cognitive functioning (SCF). The aim of this study was to evaluate SCF of breast cancer (BC) patients and to find predictors of impaired SCF. Both satisfaction and frequency of complaints about SCF were measured.

METHODS

BC patients who were about to receive chemotherapy (N = 74) and patients with a benign breast disease (BBD) (N = 63) participated. Before chemotherapy started (Time 1) and 3 months after ending chemotherapy (and at comparable moments for the BBD group) (Time 2), women completed validated questionnaires concerning the frequency of complaints and satisfaction with SCF, fatigue, perceived stress, anxiety, and depressive symptoms.

RESULTS

No differences were found between the BBD and BC patients concerning the frequency of complaints about SCF across time. Satisfaction with SCF decreased across time in BC patients but remained stable across time in BBD patients (p < 0.001; p = 0.003 after controlling for state anxiety and perceived stress). Correlation coefficients between the satisfaction and the frequency of complaints about SCF ranged between -0.26 and -0.49. Depressive symptoms and satisfaction with SCF (Time 1) predicted the frequency of complaints about SCF (Time 2). Diagnosis, frequency of complaints about SCF, and state anxiety (Time 1) predicted satisfaction with SCF (Time 2).

CONCLUSIONS

BC patients do not differ in the frequency of complaints about SCF compared with BBD patients, but their satisfaction with SCF decreased after treatment. Psychological factors predicted the frequency of complaints about SCF. Psychological factors and diagnosis predicted satisfaction with SCF.

An abnormal screening mammogram causes more anxiety than a palpable lump in benign breast disease

Being recalled for further diagnostic procedures after an abnormal screening mammogram (ASM) can evoke a high state anxiety with lowered quality of life (QoL). We examined whether these adverse psychological consequences are found in all women with benign breast disease (BBD) or are particular to women referred after ASM. In addition, the influence of the anxiety as a personality characteristic (trait anxiety) was studied. Between September 2002 and February 2010 we performed a prospective longitudinal study in six Dutch hospitals. Women referred after ASM or with a palpable lump in the breast (PL), who were subsequently diagnosed with BBD, were included. Before diagnosis (at referral) and during follow-up, questionnaires were completed examining trait anxiety (at referral), state anxiety, depressive symptoms (at referral, one, three and 6 months after diagnosis), and QoL (at referral and 12 months). Women referred after ASM (N=363) were compared with women with PL (N=401). A similar state anxiety score was found in both groups, but a lower psychological QoL score at 12 months was seen in the ASM group. In women with not-high trait anxiety those in the ASM group were more anxious with more depressive symptoms at referral, and reported impaired psychological QoL at referral and at 12 months compared with the PL group. No differences were found between ASM and PL in women with high trait anxiety, but this group scored unfavorably on anxiety, depressive symptoms and QoL compared with women with not-high trait anxiety. ASM evokes more anxiety and depressive symptoms and lowered QoL compared with women referred with PL, especially in women who are not prone to anxiety. Women should be fully informed properly about the risks and benefits of breast cancer screening programs. We recommend identifying women at risk of reduced QoL using a psychometric test.

Combined anxiety and depressive symptoms before diagnosis of breast cancer

PURPOSE

To determine the relationship between pre-diagnosis state anxiety, depressive symptoms, and combined state anxiety and depressive symptoms (CADS) with quality of life (QOL), fatigue, state anxiety and depressive symptoms one and two years after surgery in women with breast cancer.

METHODS

Women with breast problems referred to a Dutch outpatient clinic were recruited for the study. Participants (N=428) completed a set of questionnaires before diagnosis (Time0) and the women with breast cancer subsequently received questionnaires at 12 (Time1) and 24 months (Time2) after surgical treatment. The questionnaire set consisted of questionnaires on demographics, state anxiety, depressive symptoms, fatigue, QOL, neuroticism, and trait anxiety. Chi-square tests, independent samples T-tests, and multivariate linear regression analyses were used to do the analyses.

RESULTS

Before their diagnosis of breast cancer, 111 women (28%) had CADS. Of the CADS-group, a higher percentage had elevated levels of anxiety, depressive symptoms, and CADS at all follow-up moments than of the non-CADS-group. CADS-score at before diagnosis and neuroticism were the most important predictors of outcome measures at Time1 and Time2.

CONCLUSIONS

More than one in four women, who later received the diagnosis breast cancer, had elevated levels of both state anxiety and depressive symptoms (CADS) just before diagnosis. This factor was also a major predictor of QOL, state anxiety, depressive symptoms, and fatigue 12 and 24 months after surgery. This implies that women with a higher score on both state anxiety and depressive symptoms should be identified as soon as possible in the process of diagnosis and treatment of breast cancer using validated questionnaires or screening instruments. Only by identifying this group of patients, tailored psychological care can be accomplished.

Psychiatric disorders in cancer patients at a university hospital in Japan: descriptive analysis of 765 psychiatric referrals

OBJECTIVE

In cancer patients, adjustment disorders, delirium and depression have been identified as common psychiatric disorders. Although a comparable result was reported in the National Cancer Center in Japan, the nature of patients in that hospital may differ from that in local hospitals. There is a possibility to expand the findings of psycho-oncology by evaluation of the data from a local university hospital and comparison with the National Cancer Center data.

METHODS

We retrospectively reviewed the medical records of cancer patients who were referred to the Department of Psycho-Oncology at Saitama Medical University International Medical Center. We identified their characteristics and psychiatric diagnoses and compared these with the National Cancer Center data.

RESULTS

During the study period, 765 cancer patients were referred. The numbers of inpatients and outpatients were almost the same. The most common psychiatric diagnosis was adjustment disorders (24%), followed by delirium (16%) and then major depressive disorder (12%). The rank of these three was the same as that at the National Cancer Center. Outpatients constituted more than 80% of the patients with major depressive disorder. The proportion of cancer patients with schizophrenia in this study (4.3%) was higher than that in the National Cancer Center (1.6%).

CONCLUSIONS

This study revealed basic information about the consultation data of cancer patients at a local university hospital in Japan. The importance of communication with outpatients was suggested. It seems that cancer treatment for patients with schizophrenia in a local hospital is also important.
