The psychometric properties of the Icelandic version of the distress thermometer and problem list

Supportive Digital Health Service During Cancer Chemotherapy: Single-Arm Before-and-After Feasibility Study

BACKGROUND

Digital supportive cancer care is recommended to improve patient outcomes. A portal was designed and embedded within the electronic medical record and public health portal of Iceland, consisting of symptom and needs monitoring, educational material, and messaging.

OBJECTIVE

This study aims to assess (1) portal feasibility (adoption, engagement, usability, and acceptability), (2) potential predictors of usability and acceptability, and (3) the potential impact of the portal on patient-reported outcomes.

METHODS

This was a single-arm, before-and-after feasibility study at a university hospital among patients with cancer who were undergoing chemotherapy. Participation included filling out the Edmonton Symptom Assessment System-Revised (ESASr) weekly and the Distress Thermometer and Problem List (DT&PL) 3 times; reading educational material and messaging; and completing study questionnaires. Clinical and portal engagement data were collected from medical records. Data from patients were collected electronically at baseline and 7 to 10 days after the third chemotherapy round. Usability was assessed using the System Usability Scale (score 0-100), and acceptability was assessed using a 35-item survey (score 1-5). Patient-reported outcome measures included ESASr and DT&PL; a single-item scale for quality of life, family support, and quality of care; and multi-item scales for health literacy (Brief Health Literacy Screener), health engagement (Patient Health Engagement Scale), self-care self-efficacy (Self-Care Self-Efficacy scale), symptom interference (MD Anderson Symptom Inventory), knowledge expectations (Hospital Patients' Knowledge Expectations), and received knowledge (Hospital Patients' Received Knowledge). Health care professionals were interviewed regarding portal feasibility.

RESULTS

The portal adoption rate was 72% (103/143), and the portal use rate was 76.7% (79/103) over a mean 8.6 (SD 2.7) weeks. The study completion rate was 67% (69/103). The combined completion rate of the ESASr and DT&PL was 78.4% (685/874). Patients received a mean 41 (SD 13) information leaflets; 33% (26/79) initiated messaging, 73% (58/79) received messages, and 85% (67/79) received follow-up phone calls. The mean System Usability Scale score was 72.3 (SD 14.7), indicating good usability. Usability was predicted by age (β=-.45), ESASr engagement (β=.5), symptom interference (β=.4), and received knowledge (β=.41). The mean acceptability score, 3.97 (SD 0.5), was above average and predicted by age (β=-.31), ESASr engagement (β=.37), symptom interference (β=.60), self-care self-efficacy (β=.37), and received knowledge (β=.41). ESASr scores improved for total symptom distress (P=.003; Cohen d=0.36), physical symptoms (P=.01; Cohen d=0.31), and emotional symptoms (P=.01; Cohen d=0.31). Daily symptom interference increased (P=.03; Cohen d=0.28), quality of life improved (P=.03; Cohen d=0.27) and health engagement (P=.006; Cohen d=0.35) improved, while knowledge expectations decreased (P≤.001; Cohen d=2.57). Health care professionals were positive toward the portal but called for clearer role delineation and follow-up.

CONCLUSIONS

This study supports the feasibility of a support portal and the results indicate the possibility of improving patient outcomes, but further developments are warranted.

A distress thermometer with a cutoff score of ≥ 6 is the optimal point to identify highly distressed patients with advanced cancer stages in resource-limited countries without palliative care services

Purpose

Although the distress thermometer (DT) scale has been widely validated and used in different cancer types and settings, an optimal cutoff score of DT is not defined to screen advanced cancer patients. The study aimed to define the optimal DT’s cutoff score among advanced cancer patients in resource-limited countries without palliative care services and to assess the prevalence and factors associated with psychological distress among this population.

Methods

A secondary analysis was performed. Three hundred seventy-nine patients were recruited from Palestine. Participants completed the DT and the Hospital Anxiety and Depression Scale (HADS). Receiver operating characteristic analysis (ROC) was used to define the optimal cutoff score for the DT against HADS-Total ≥15. Multiple logistic regression was utilized for identifying the factors associated with psychological distress of the DT.

Results

A DT cutoff score ≥ 6 correctly identified 74% of HADS distress cases and 77% of HADS non-distress cases, with a positive predictive value (PPV) and negative predictive value (NPV) of 97% and 18%, respectively. The prevalence of distress was found to be 70.7%, and the major sources of distress were related to physical (n = 373; 98.4%) and emotional problems (n = 359; 94.7%). Patients with colon (OR = 0.44, 95% CI: 0.31 – 0.62) and lymphoid cancers (OR = 0.41, 95% CI: 0.26 – 0.64) were less likely to have psychological distress than patients with other types of cancer, whereas patients with lung (OR = 1.80, 95% CI: 1.20 – 2.70) and bone cancers (OR = 1.75, 95% CI: 1.14 – 2.68) were more likely to experience it.

Conclusion

A cutoff DT score of 6 appeared acceptable and effective for screening distress in patients with advanced cancer stages. Palestinian patients exhibited a high level of distress, and the high prevalence supports the argument of using a DT within the standard delivery of cancer care to identify highly distressed patients. These highly distressed patients should then be involved in a psychological intervention programme.

A systematic review of the translation and validation methods used for the national comprehensive cancer network distress thermometer in non-English speaking countries

OBJECTIVE

The National Comprehensive Cancer Network (NCCN) distress thermometer (DT) was developed as a brief screening tool for detecting distress in cancer patients. Conceptually, distress was considered a more acceptable and inclusive term than other psychological terms such as depression or anxiety. It is used extensively in the United States and other English-speaking countries. We aim to describe the translation and validation methods of the DT and describe the recommended cutoff scores used to identify cancer patients experiencing clinically significant distress.

METHODS

Nine bibliographic databases were searched using keywords to identify original research studies for non-English speaking countries' cancer patients. Full articles were independently assessed for inclusion and data extraction by two authors.

RESULTS

The review of 4442 articles yielded 39 articles that validated the DT. We identified 20 languages in 25 countries. In all but one country, investigators were able to agree upon a word or phrase that meant distress in their native language that was subsequently validated against standardized instruments. Asian, Middle Eastern and European counties recommended cutoff score of 4 or 5 to identify clinically significant distress; however, European Union countries had a range of 2 to 7.

CONCLUSIONS

Use of the translated DT with non-English speaking cancer patients provides a simple and quick tool to identify high distress. Similar to NCCN, the cutoff score of 4 or 5 was suggested by 78% of the studies; however, more studies of different types of cancer and within and among more countries will strengthen a recommended global DT cutoff score.

Brief psychological distress screening on a cancer helpline: How nurses introduce, and callers respond to, the Distress Thermometer

PURPOSE

Helplines are increasingly used to provide information and support for people affected by cancer, and the distress routinely associated with diagnosis and treatment is a major focus for those providing such care. Little is known, however, about how the Distress Thermometer (DT), a widely used tool for the assessment of patient/carer distress on cancer-support telephone helplines, is introduced and used in such settings.

METHOD

Using the method of conversation analysis, we present a qualitative analysis of DT use in actual telephone interactions by looking closely at how particular practices shape interaction on a cancer helpline. Specifically, we examine how oncology-trained nurse call-takers used the DT, in situ, as a tool for assessing callers, as well as examining how callers responded to this brief screening tool.

RESULTS

Our findings show how particular positioning of the DT in the call, and particular forms of its delivery, tend to generate brief responses from callers that avoid topicalization of distress, and tend not to be associated with referral to support services.

CONCLUSIONS

Implications for successful integration of the DT as a screening tool in cancer- and other health-helpline interactions, as well as for effective training of users, are discussed.

Associated factors of distress in patients with advanced cancer: A retrospective study

OBJECTIVE

The objective of this study was to assess the psychosocial distress and associated factors in advanced cancer patients consulting at the outpatient Palliative Care Unit at the National Cancer Institute in Mexico City.

DESIGN

A retrospective study was conducted using electronic records (June 2015 to December 2016).

SAMPLE

A total of 646 patients with advanced cancer during their first visit to the outpatient palliative care unit at the National Cancer Institute in Mexico were evaluated using the Distress Thermometer (DT) and ECOG performance status scores.

FINDINGS

Overall, 62% were women, with a median age of 57 years, and married (54.8%). The most frequent diagnosis was gastrointestinal cancer (28.6%), and 38.9% had a functional performance status of ECOG 2. The median DT score was 4.0 (IQR = 2-6), with 56% reporting DT scores ≥4. The three most frequent problems ≥4 were sadness (82.6%), feeling weak (81.2%), worry (79.6%), and <4 were feeling weak (57.7%), fatigue (55.6%), and financial security (52.1%). The variables associated with distress according to the multiple logistic regression analysis were problems with housing (OR = 2.661, 95% CI = 1.538-4.602), sadness (OR = 2.533, 95% CI = 1.615-3.973), transportation (OR = 1.732, 95% CI = 1.157-2.591), eating (OR = 1.626, 95% CI = 1.093-2.417), nervousness (OR = 1.547, 95% CI = 1.014-2.360), and sleep (OR = 1.469, 95% CI = 1.980-2.203).

CONCLUSION

The principal factors were related to distress levels, housing problems, transportation issues, and emotional problems such as sadness, nervousness, lower functionality, and younger age. Therefore, psychosocial support is of considerable relevance in palliative care. These findings will help clinicians understand the distress of patients with advanced cancer in palliative care in Latin American countries.

The Evaluation of a Mind-Body Intervention (MBT-T) for Stress Reduction in Academic Settings: A Pilot Study

This study is aimed at evaluating the outcomes of mind-body transformation therapy (MBT-T), previously known as the creative psychosocial genomic healing experience© (CPGHE). The intervention was aimed at reducing the perceived level of stress in two non-clinical groups of students with different educational levels and different expertise in the domain of well-being. Whereas participants from the first group were first-year university students, participants from the second group were students attending a post-graduate program in psychotherapy. All participants (n = 159) were exposed to a single session of MBT-T, each group in a separate session. The results of two paired-samples t-tests, conducted separately on the two samples, showed that there was a statistically significant reduction in the participants' perceived level of stress between pre- and post-intervention states in both samples (t₈₈ = 5.39, p < 0.001; t₅₃ = 4.56, p < 0.001 respectively). The results, therefore, showed that a single session of MBT-T was beneficial in reducing the perceived level of stress in both first-year university students and students attending a post-graduate program in psychotherapy, regardless of educational level and expertise in the domain of well-being.

Factors Associated with Depression in African American Patients Being Treated for Cancer Pain

BACKGROUND

Among cancer patients in the United States, African American cancer patients have the highest mortality rate and shortest survival rate. Although depression is known as a predictor of mortality in cancer and a potential barrier to health care utilization, research on depression in African American patients is limited. Cancer pain can interfere with an individual's ability to cope with depression.

AIMS

To identify factors that are associated with a positive screening of depressive symptoms assessed by the PHQ-8 in African American patients treated for cancer pain.

DESIGN

Secondary data analysis of a cross-sectional study of opioid adherence.

SETTING

Medical oncology, palliative care, and radiation oncology clinics in Atlanta, Georgia.

PARTICIPANTS/SUBJECTS

African American patients with cancer pain in the parent study.

METHODS

Independent samples t-test was used to assess variable correlations with and without depressive symptoms. Adjusted logistic regression was conducted to identify factors that were associated with presence of depressive symptoms.

RESULTS

Mean patient age was 55.6 years, and nearly 38% had a PHQ-8 score of >10 indicating presence of moderate to severe depressive symptoms. Participants with depressive symptoms had significantly higher means for anxiety and pain interference with mood than those without depressive symptoms. Factors that were significantly associated with depressive symptoms were anxiety, pain interfering with mood, and lack of involvement with a religious congregation.

CONCLUSIONS

The findings of this study help to identify African American cancer patients at risk for depression and demonstrates the need for increased screening for depression in this underserved population.

Do rapid emotional thermometers correlate with multidimensional validated structured questionnaires in low-risk prostate cancer?

PURPOSE

To promptly identify mental suffering in low-risk prostate cancer (LRPC) patients, vulnerable to over- and undertreatment, we evaluated the correlation of rapid emotional thermometers (ET) with multidimensional validated structured questionnaires.

METHODS

At diagnosis, consecutive LRPC patients underwent five ET domains: emotional suffering, anxiety, depression (DT), revolt and need for help and multidimensional questionnaires: beck anxiety inventory (BAI), beck depression inventory (BDI), beck hopelessness scale, SF36 (physical functioning PF, role limitations due to physical health RP, bodily pain BP, general health perceptions GH, vitality VT, social functioning SF, role limitations due to emotional problems RE and general mental health MH), international index of erectile function and international prostate symptom score (IPSS).

RESULTS

Among 30 included patients, mean age 67.4 y (52-74), 20 days after the diagnosis (15-30), mean time to obtain ET 27 s (15-57) and all questionnaires 36.7 min (31-49), ETs showed moderate/strong Spearman correlation among themselves. DT domain displayed the best correlation to most of the multidimensional validated structured questionnaires: moderate to BDI, SF-36 (PF, GH, VT, SF, RE, MH) and IPSS and strong to BAI.

CONCLUSION

DT revealed the best correlation to validated structured questionnaires of diverse dimensions with clear potential for quick screening of patients with psychological suffering and in need of further evaluation and support.

Screening for Psychologic Distress in Taiwanese Cancer Inpatients Using the National Comprehensive Cancer Network Distress Thermometer: The Effects of Patients' Sex and Chemotherapy Experience

BACKGROUND

Patients with cancer often experience distress, and early detection and management of psychologic distress are vital for improving patients' outcomes.

OBJECTIVE

This study investigates the validity and determines the optimal cutoff score-for clinically significant distress-for the Taiwanese Distress Thermometer (DT).

METHODS

This study consisted of 768 inpatients diagnosed with cancer in a general hospital in southern Taiwan. The condition of psychologic distress was assessed in these patients using the DT and Chinese Health Questionnaire-12. We applied a receiver operating characteristic curve analysis to evaluate the discriminative validity of the DT, adopting the Chinese Health Questionnaire-12 score of ≥4 as having psychologic distress. We also used a logistic regression model to determine the associated factors of the concordant screening results of both the DT and the Chinese Health Questionnaire-12.

RESULTS

The DT demonstrated an acceptable validity of discriminating between patients with psychologic distress and those without (area under curve = 0.787). We found a DT score of 4 to be the best cutoff value, with a 72.2% of sensitivity, a specificity of 80.0%, and an accuracy of 79.2%. The concurrence between the DT and the Chinese Health Questionnaire-12 was related to patients' sex and chemotherapy treatment experience.

CONCLUSION

Our findings show that the DT has acceptable psychometric properties for identifying psychologic distress in patients with cancer. However, the optimal cutoff point of the DT may vary with patients' characteristics.

Prevalence, risk factors, and the desire for help of distressed newly diagnosed cancer patients: A large-sample study

Objective:

Beginning in 2007, all newly diagnosed cancer patients at the Koo Foundation Sun Yat-Sen Cancer Center (KF–SYSCC) were screened for psychosocial distress. Our social workers, as part of the psychosocial care team (PCT), have engaged in proactive outreach with patients identified as distressed. The goal of the present study was to assess the prevalence of psychosocial distress and the extent of contact between the PCT and distressed patients.

Method:

Newly diagnosed patients who were treated at KF–SYSCC between 2007 and 2010 for cancer were eligible if there were at least 100 patients with the same type of cancer. Before treatment began, they were screened with the Pain Scale and the Distress Thermometer (DT) and had the option to specify a desire for help. The rates of distress were analyzed by cancer type and by probable related factors. Information regarding contact with the PCT was retrieved from computerized databases.

Results:

Overall, some 5,335 cancer patients representing 12 major cancer types were included in our study. Of these, 1,771 (33.20%) were significantly distressed. By multivariate logistic regression, younger age, female gender, higher pain score, and disease stage, but not cancer type, were found to be associated with higher rates of distress. Among these distressed patients, 628 (36%) had some contact with the PCT.

Significance of results:

This Taiwanese study with a large sample size revealed a prevalence rate of psychosocial distress similar to rates found in Western countries. Contact with the PCT was established in only 36% of significantly distressed patients, despite a proactive outreach program. It is very important to have screening results made available in a timely fashion to the psycho-oncology team so that appropriate care can be offered promptly.

Accuracy of the Distress Thermometer for home care patients with palliative care needs in Germany

OBJECTIVE

Our aim was to examine the accuracy of the German version of the Distress Thermometer (DT) compared with the Hospital Anxiety and Depression Scale (HADS) in patients with palliative care needs living at home.

METHOD

Ours was a 15-month cross-sectional study beginning in September of 2013 in Germany with consecutive patients cared for by a palliative home care service. The survey was implemented during the initial visit by a home care team. Patients were excluded if they were under 18 years of age, mentally or physically unable to complete the assessment questionnaires as judged by their healthcare worker, or unable to understand the German language. During the first encounter, the DT and HADS were applied, and sociodemographic and medical data were collected.

RESULTS

A total of 89 persons completed both the HADS and DT questionnaires (response rate = 59.7%; mean age = 67 years; female = 55.1%; married = 65.2%; living home with relatives = 73.0%; oncological condition = 92.1%; Karnofsky Performance Scale [KPS] score: 0-40 = 30.3%, 50-70 = 57.3%, >80 = 6.7%). The mean DT score was 6.3 (±2.3), with 84.3% of participants scoring above the DT cutoff (≥4). The mean HADStotal score was 17.9 (±7.8), where 64% of participants had a total HADS score (HADStotal) ≥15, 51.7% reported anxiety (HADSanxiety ≥ 8), and 73% reported depression (HADSdepression ≥ 8). Using the HADS as a gold standard, a DT cutoff score ≥5 was optimal for identifying severe distress in patients with palliative care needs, with a sensitivity of 93.0%, a specificity of 34.4%, a positive predictive value (PPV) of 73.3%, and likelihood ratios LR+ = 1.42 (<3) and -LR = 0.203 (<0.3).

SIGNIFICANCE OF RESULTS

The DT performed satisfactorily compared to the HADS in screening for distress in our study and can be employed as an instrument for identification of patients with distress. Consequent to the high prevalence of distress, we recommend its routine use for screening distressed persons at home with palliative care needs in order to offer adequate support.

How much psychological distress is experienced at home by patients with palliative care needs in Germany? A cross-sectional study using the Distress Thermometer

Objective:

The aims of the present study were (1) to describe the prevalence of psychosocial distress in palliative care patients living at home and the related factors, and (2) to test implementation of the Distress Thermometer (DT) within a home-based palliative care service.

Method:

Ours was a 15-month prospective study beginning in September of 2013 in western Germany with consecutive patients cared for by a home care palliative care service. The research was implemented during the first visit by the home care team. Patients were excluded if they were under 18 years of age, mentally or physically unable to complete the assessment questionnaires as judged by their healthcare worker, or unable to understand the German language. During the first encounter, the Distress Thermometer (DT), a Problem List (PL), and a structured questionnaire for evaluation were applied and sociodemographic and medical data collected.

Results:

A total of 103 patients (response rate = 70%; mean age = 67; female = 54%; married = 67%; oncological condition = 91%; Karnofsky Performance Status [KPS] score 0–40 = 34%, 50–70 = 60%, >80 = 6%) were included. The incidence of distress (DT score ≥4) was 89.3% (mean = 6.3 ± 2.5). No statistical association was found between level of distress and sociodemographic or medical factors. The five most reported problems were “fatigue” (90%), “getting around” (84%), “eating” (63%), “bathing/dressing” (60%), and “sleep” (57%). The number of problems reported correlated with level of distress (ρ = 0.34). The DT was comprehensible, and 80% considered its completion as unremarkable, while 14% found it “relieving.”

Significance of results:

A significant proportion of patients treated at home reported symptoms of distress. The most oft-mentioned problems were physical and emotional in nature. The findings of our study highlight the importance of creating new concepts and structures in order to address the psychosocial needs of patients in home care with palliative needs.

Which items on the distress thermometer problem list are the most distressing?

PURPOSE

The importance of distress identification and management in oncology has been established. We examined the relationship between distress and unmet bio-psychosocial needs, applying advanced statistical techniques, to identify which needs have the closest relationship to distress.

METHODS

Oncology outpatients (n = 1066) undergoing QUICATOUCH screening in an Australian cancer centre completed the distress thermometer (DT) and problem list (PL). Principal component analysis (PCA), logistic regression and classification and regression tree (CART) analyses tested the relationship between DT score (at a cut-off point of 4) and PL items.

RESULTS

Sixteen items were reported by <5 % of participants. PCA analysis identified four major components. Logistic regression analysis indicated three of these component scores, and four individual items (20 items in total) demonstrated a significant independent relationship with distress. The best CART model contained only two PL items: 'worry' and 'depression'.

CONCLUSIONS

The DT and PL function as intended, quantifying negative emotional experience (distress) and identifying bio-psychosocial sources of distress. We offer two suggestions to minimise PL response time whilst targeting PL items most related to distress, thereby increasing clinical utility. To identify patients who might require specialised psychological services, we suggest the DT followed by a short, case-finding instrument for patients over threshold on the DT. To identify other important sources of distress, we suggest using a modified PL of 14 key items, with the 15th item 'any other problem' as a simple safety net question. Shorter times for patient completion and clinician response to endorsed PL items will maximise acceptance and clinical utility.

Changes in attitudes, practices and barriers among oncology health care professionals regarding sexual health care: Outcomes from a 2-year educational intervention at a University Hospital

PURPOSE

To examine the attitudes, practices and perceived barriers in relation to a sexual health care educational intervention among oncology health care professionals at the Landspítali-National University Hospital of Iceland.

METHODS

The design was quasi experimental, pre - post test time series. A comprehensive educational intervention project, including two workshops, was implemented over a two year time period. A questionnaire was mailed electronically to all nurses and physicians within oncology at baseline (T1, N = 206), after 10 months (T2, N = 216) and 16 months (T3, N = 210).

RESULTS

The response rate was 66% at T1, 45% at T2 and 38% at T3. At all time points, the majority of participants (90%) regarded communication about sexuality part of their responsibilities. Mean scores on having enough knowledge and training, and in six of eight practice issues increased significantly over time. Overall, 10-16% reported discussing sexuality-related issues with more than 50% of patients and the frequency was significantly higher among workshop attendants (31%) than non-attendants (11%). Overall, the most common barriers for discussing sexuality were "lack of training" (38%) and "difficult issue to discuss" (27%), but the former barrier decreased significantly by 22% over time.

CONCLUSIONS

The intervention was successful in improving perception of having enough knowledge and training in providing sexual health care. Still, the issue remains sensitive and difficult to address for the majority of oncology health care professionals. Specific training in sexual health care, including workshops, should be available to health care professionals within oncology.

Toward patient-centered care: a systematic review of how to ask questions that matter to patients

Clinicians rarely systematically document how their patients are feeling. Single item questions have been created to help obtain and monitor patient relevant outcomes, a requirement of patient-centered care.The objective of this review was to identify the psychometric properties for single items related to health aspects that only the patient can report (health perception, stress, pain, fatigue, depression, anxiety, and sleep quality). A secondary objective was to create a bank of valid single items in a format suitable for use in clinical practice.Data sources used were Ovid MEDLINE (1948 to May 2013), EMBASE (1960 to May 2013), and the Cumulative Index to Nursing and Allied Health Literature (1960 to May 2013).For the study appraisal, 24 articles were systematically reviewed. A critical appraisal tool was used to determine the quality of articles.Items were included if they were tested as single items, related to the construct, measured symptom severity, and referred to recent experiences.The psychometric properties of each item were extracted. Validity and reliability was observed for the items when compared with clinical interviews or well-validated measures. The items for general health perception and anxiety showed weak to moderate strength correlations (r = 0.28-0.70). The depression and stress items showed good area under the receiver operating characteristic curve of 0.85 and 0.73-0.88, respectively, with high sensitivity and specificity. The fatigue item demonstrated a strong effect size and correlations up to r = 0.80. The 2 pain items and the sleep item showed high reliability (intraclass correlation coefficient [ICC] = 0.85, κ = 0.76, ICC = 0.9, respectively).The search targeted articles about psychometric properties of single items. Articles that did not have this as the primary objective may have been missed. Furthermore, not all the articles included had the complete set of psychometric properties for each item.There is sufficient evidence to warrant the use of single items in clinical practice. They are simple, easily implemented, and efficient and thus provide an alternative to multi-item questionnaires. To facilitate their use, the top performing items were combined into the visual analog health states, which provides a quick profile of how the patient is feeling. This information would be useful for regular long-term monitoring.

Measurement of distress and its alteration during treatment in patients with nasopharyngeal carcinoma

BACKGROUND

We examined the criterion-related validity of the Distress Thermometer (DT) for screening distress in patients with nasopharyngeal carcinoma (NPC) and investigated prospectively how distress changes.

METHODS

In the cross-sectional study, the DT was tested against the Hospital Anxiety and Depression Scale (HADS) in 295 patients with NPC. In the prospective study, 61 newly diagnosed patients with NPC completed the DT and HADS 6 times.

RESULTS

Adopting HADS as the standard tool for screening distress, 31.5% of the patients with NPC had distress. A DT cutoff score ≥ 4 had best sensitivity (0.73) and specificity (0.85). In the prospective study, the proportion of patients with distress rose significantly during treatment.

CONCLUSION

Receiver operating characteristic (ROC) findings provide initial support for the validity of the DT among patients with NPC. Nearly one third of patients with NPC exceeded cutoff values for distress in the cross-sectional study. In the prospective study, the level of distress increased significantly during concurrent chemoradiotherapy for patients with NPC.

The validity of the distress thermometer in prostate cancer populations

Background

The Distress Thermometer (DT) is widely recommended for screening for distress after cancer. However, the validity of the DT in men with prostate cancer and over differing time points from diagnosis has not been well examined.

Method

Receiver operating characteristics analyses were used to evaluate the diagnostic accuracy of the DT compared with three commonly used standardised scales in two prospective and one cross-sectional survey of men with prostate cancer (n = 740, 189 and 463, respectively). Comparison scales included the Impact of Event Scale – Revised (IES-R, Study 1), the Hospital Anxiety and Depression Scale (HADS, Study 2) and the Brief Symptom Inventory-18 (BSI-18, Study 3).

Results

Study 1: the DT showed good accuracy against the IES-R at all time points (area under curves (AUCs) ranging from 0.84 to 0.88) and sensitivity was high (>85%). Study 2: the DT performed well against both the anxiety and depression subscales for HADS at baseline (AUC = 0.84 and 0.82, respectively), but sensitivity decreased substantially after 12 months. Study 3: validity was high for the anxiety (AUC = 0.90, sensitivity = 90%) and depression (AUC = 0.85, sensitivity = 74%) subscales of the BSI-18 but was poorer for somatization (AUC = 0.67, sensitivity = 52%). A DT cut-off between ≥3 and ≥6 maximised sensitivity and specificity across analyses.

Conclusions

The DT is a valid tool to detect cancer-specific distress, anxiety and depression among prostate cancer patients, particularly close to diagnosis. A cut-off of ≥4 may be optimal soon after diagnosis, and for longer-term assessments, ≥3 was supported.

Do cancer and treatment type affect distress?

OBJECTIVE

We examined differences in distress levels and Distress Thermometer (DT) cutoff scores between different cancer types. The effect of socio-demographic and illness-related variables on distress was also examined.

METHODS

One thousand three hundred fifty patients (response = 51%) completed questions on socio-demographic and illness-related variables, the Dutch version of the DT and Problem List, and the Hospital Anxiety and Depression Scale. Receiver operating characteristics analyses were performed to determine cancer specific cutoff scores. Univariate and multivariate effects of socio-demographic and illness-related variables (including cancer type) on distress were examined.

RESULTS

Prostate cancer patients reported significantly lower DT scores (M = 2.5 ± 2.5) and the cutoff score was lower (≥ 4) than in patients with most other cancer types (M varied between 3.4 and 5.1; cutoff ≥ 5). Multivariate analyses (F = 10.86, p < .001, R(2) = 0.08) showed an independent significant effect of four variables on distress: intensive treatment (β = .10, any (combination of) treatment but surgery only and 'wait and see'); a non-prostate cancer type (β = -.17); the interaction between gender and age (β = -.12, highest distress in younger women as compared with older women and younger and older men); and the interaction between cancer type and treatment intensity (β = .08, lowest scores in prostate cancer patients receiving non-intensive treatment as compared with their counterparts).

CONCLUSIONS

Distress and cutoff score in prostate cancer patients were lower than in patients with other cancer types. Additionally, younger women and patients receiving treatment other than surgery only or 'wait and see' are at risk for higher distress. These results can help identify patients possibly in need of referral to professional psychosocial and/or allied health care.

Measurement of distress in Chinese inpatients with lymphoma

PURPOSE

The aim of this study was to assess the levels and sources of distress in patients with lymphoma. This study also focused on the influence of factors of the level of distress and the cutoff score using the Distress Thermometer (DT) relative to the Hospital Anxiety and Depression Scale (HADS).

METHOD

DT and HADS were used to estimate the psychological status of 323 eligible lymphoma patients. The DT was evaluated against the HADS for its sensitivity and specificity.

RESULTS

One hundred and ninety-three (59.7%) lymphoma patients experienced overall distress on the HADS, with 137 (42.4%) experiencing anxiety and 114 (35.3%) suffering from depression. There were 199 (61.6%) and 163 (50.5%) patients with distress score ≥ 4 and ≥ 5, respectively. DT was significantly correlated with the HADS-total (T) (r=0.820, p<0.001), HADS-depression (D) (r=0.763, p<0.001), and HADS-anxiety (A) (r=0.738, p<0.001). The consistency of the DT and HADS was favorable (coherence index=0.6030, p<0.01) when the cutoff score was 5 for the DT. Referring to the cutoff of 15 on HADS, 5 on DT yielded optimal specificity (0.869, p<0.001) and sensitivity (0.756, p<0.001). In multiple logistic regression analysis, patients with 'B symptoms' were more likely to have a distress score ≥ 5 [OR=4.512, p<0.05, 95% CI 1.953-10.467].

CONCLUSION

DT is efficacious for screening for anxiety and depression in lymphoma patients.
