Possible substantive improvements in the structure of the Quality of Life in Adult Cancer Survivors (QLACS) scale? A study based on its Spanish version.

PURPOSE: Quality of Life in Adult Cancer Survivors (QLACS) scale is one of the most commonly used and validated measures to assess the Health-Related Quality of Life (HRQoL) in this population. However, there are some aspects related to its structure that still deserve consideration. The aim of this study was to test the substantive improvement over the original QLACS structure resulting from several proposals reflected in the literature. METHOD: Using a cross-sectional design and Confirmatory Factorial Analysis, we explored those proposals. Reliability, convergent validity, and factor invariance across three cancer survivorships phases (re-entry, early, and long term) were also analyzed. 1.862 post-treatment survivors of diverse cancer types completed the Spanish versions of QLACS, Brief Symptom Inventory-18 (BSI-18), and Subjective Happiness Scale (SHS). RESULTS: The original model with twelve domains, grouped (with the exception of benefits) into a single total score, versus two subtotal (Generic and Cancer-specific) obtained a good fit. The values of Cronbach's alpha, Composite reliability, Average Variance Extracted indexes, and Pearson correlations supported the internal consistency and temporal stability (interval of 2-3 weeks) of the QLACS. Results also showed its adequate convergent validity and an invariant factor structure across survival periods (re-entry survivorship, early survivorship, long-term survivorship). CONCLUSION: In its original structure, albeit the replacement of the scores on the two subscales by a total score, our results support QLACS as a valid and useful tool for the assessment of HRQoL in post-treatment cancer survivors throughout the different survival phases.

Emotional distress and unmet supportive care needs in survivors of breast cancer beyond the end of primary treatment.

PURPOSE: Cancer patient survival rates are rapidly growing, and further data are needed on the impact of the disease beyond diagnosis and treatment phases. The aims of this study were to analyze the prevalence and sociodemographic and medical risk factors of clinical distress. Additionally, we also explore the relationship between unmet psychosocial needs and both clinical distress and subgroups of survival periods. METHODS: A cross-sectional study of 450 women who at least 1 month before had completed the primary treatment for breast cancer was conducted. The Brief Symptom Inventory 18 and the Cancer Survivors Unmet Needs measure were used. RESULTS: One in four women showed clinical distress related to unmet psychosocial needs. None of the sociodemographic and medical predictors was associated with clinical distress. Needs focused on the possibility of recurrence and its cognitive-emotional impact were the most frequent. Needs tended to decrease through periods of survival; however, there was a considerable level of unmet needs even among long-term survivors. CONCLUSIONS: The findings highlight the relevance of extending psychosocial care beyond the breast cancer primary medical treatment. Early and regular screen for distress and unmet supportive needs permits to identify high-risk groups that likely benefit from targeted preventive interventions.

Confirming the mechanisms behind cognitive-behavioural therapy effectiveness in chronic pain using structural equation modeling in a sample of patients with temporomandibular disorders.

OBJECTIVE: To evaluate whether therapeutic mechanisms assumed to explain the effect of cognitive behavioural therapy (CBT) concerning temporomandibular symptoms are confirmed by structural equation modelling. METHOD: Patients were randomly assigned to either an experimental group receiving CBT (N = 41) or a standard therapy control group (N = 31). Subjects were assessed before and after intervention using mediator variables hypothesized according to the CBT model, as well as outcome variables and other socio-demographic and clinical measures. RESULTS: The results confirm that the effect of treatment on pain intensity was partially mediated by distress, catastrophizing, perceived control, distraction, and mental self-control. The self-medication frequency was partially mediated by distraction. Pain interference was partially mediated by distress, distraction, and mental self-control. Reduction in the number of painful points on palpation was partially explained by distress, although in this case, there was a significant direct effect of treatment not mediated by other variables. CONCLUSIONS: The results could set the principles for the development of more efficient and effective cognitive behavioural interventions for chronic pain.

Patient-reported assessment of compassion in Spanish: a systematic review.

Aims and objectives: This systematic review aims to: (1) explore which tools have been used in Spanish to measure compassion; (2) know which of these tools could be used to assess compassion in healthcare settings from the perspective of patients; (3) evaluate the quality of these patient-reported measures in Spanish contexts; and (4) determine which of these instruments would be best suited to be used in healthcare settings. Background: Compassion has been recognized as a fundamental dimension of quality healthcare. Methods: Several scientific databases were consulted for relevant records published up to December 16th, 2021. In accordance with PRISMA guidelines, 64 studies were included. Results and conclusions: while existing instruments, validated in Spanish, allow for the measurement of self-compassion or compassion to others, there are no valid and reliable measures currently available in Spanish to measure patient-reported compassion. Relevance to clinical practice: In order to ensure and promote compassion in the health care context, it is essential to have a valid and reliable tool to measure this construct in a patient-informed way, and this is currently not possible in the Spanish-speaking context because of the lack of such an instrument in Spanish.

Use of the Distress Thermometer in Cancer Survivors: Convergent Validity and Diagnostic Accuracy in a Spanish Sample.

OBJECTIVES: To explore the performance of the National Comprehensive Cancer Network Distress Thermometer (DT) as a distress screening tool in cancer survivors. SAMPLE & SETTING: 236 Spanish adult-onset cancer survivors who visited the Fundación Instituto Valenciano de Oncología in Valencia, Spain, for follow-up appointments. METHODS & VARIABLES: Survivors completed the DT and the Brief Symptom Inventory 18 (BSI-18), which has established a cutoff score for identifying clinically significant distress. RESULTS: Receiver operating characteristic curve analysis of the DT scores relative to the BSI-18 cutoff score showed good overall accuracy. For a score of 5 or greater, sensitivity, specificity, positive predictive value, negative predictive value, and clinical utility indexes indicated that the DT appeared to be satisfactory for screening but had restricted use for case finding. IMPLICATIONS FOR NURSING: Screening for and responding to distress is considered an important part of nursing practice. The DT is suitable for use as a first-stage, quick-detection instrument in a two-step screening process to rule out noncases among Spanish post-treatment cancer survivors.

Mini-Mental Adjustment to Cancer Scale: Construct validation in Spanish breast cancer patients.

OBJECTIVE: The Mini-Mental Adjustment to Cancer Scale (MiniMAC) is widely used to evaluate cancer patients' psychological responses to diagnosis and treatment. Validation studies of the scale have shown inconsistency in the obtained factor structures. The aim of this study was to explore the factor structure, using Confirmatory Factor Analysis (CFA), and other psychometric properties of the MiniMAC in Spanish breast cancer patients. METHODS: A sample of 368 women with breast cancer completed the MiniMAC and the 18 items version of the Brief Symptom Inventory (BSI-18). RESULTS: The original pentafactorial model and three additional models derived from the empirical research -two first-order structures with four and three factors, and a second-order bifactorial structure- were tested. The five-factor model showed the best model fit and largely replicated the original MiniMAC's subscales. Five factors had acceptable reliability and showed modest correlations with emotional distress in the expected direction. CONCLUSIONS: The Spanish version of the MiniMAC has a satisfactory overall performance and serves as a brief, reliable and valid tool measuring cognitive appraisals and ensuing reactions to cancer.

[Age, health beliefs, and attendance to a mammography screening program in the community of Valencia]. / Edad, creencias de salud y asistencia a un programa de cribado mamográfico en la comunidad Valenciana.

BACKGROUND: Age has a significant bearing on health beliefs related to participating in breast cancer screening programs. This study is aimed at analyzing the breast cancer-related beliefs and attitudes influencing screening program participation among different age groups. METHODS: In a transversal study, a comparison is drawn between the health-related beliefs of a group of women participating in a screening program and a group of non-participating women, taking into account three age ranges (under age 50 (N = 279), 50-60 age range (N = 463), and over age 60 (N = 271). RESULTS: Some variables significantly differ between the participating and non-participating women solely in certain subgroups: perceived severity (50-60 age group: F = 5.14; p < 0.01); perceived benefits (under age 50: F = 8, 18; p < 0.01; over age 60: F = 4.54; p < .05); mammogram-related attitude (under age 50: F = 56.67; p? .001; over age 60: F = 18.42; p < 0.001); professional health checkups (under age 50: F = 11.30: p < 0.01) and luck or chance (under age 50: F = 3.78; p < 0.05; 50-60 age group: F = 4.29; p < 0.001). More specific beliefs, assessed by items from these scales, are also statistically significant (p < 0.05), although only for certain age groups. CONCLUSIONS: Women's breast cancer prevention program participation related beliefs and/or attitudes differ in terms of their age.

Psychometric properties of the Brief Symptom Inventory-18 in a heterogeneous sample of adult cancer patients / Propiedades psicométricas del Inventario Breve de Síntomas-18 en una muestra heterogénea de pacientes de cáncer adulto

Abstract The Brief Symptom Inventory-18 (BSI-18) is a self-reporting screening instrument that is widely used to assess global psychological distress and three kinds of symptoms: anxiety, depression, and somatization. The present study tests the factor structure of the BSI-18 using confirmatory factor analysis (CFA), its reliability, convergent validity, and invariance for both sexes. A heterogeneous sample of 1183 cancer patients completed the BSI 18 and the NCCN Problem List. Hierarchical models of three and four subscales with GSI as a main factor provided an adequate and similar model fit. Nonetheless, the hierarchical three-factor model (the theoretical proposal) was selected for methodological and theoretical reasons. Reliability indexes (Cronbach's alpha and Composite Reliability) were satisfactory. The positive significant associations between BSI-18 (GSI and subscales) and emotional and physical categories of the Problem List showed the suitable convergent validity of the instrument. Finally, multigroup CFA revealed an essentially invariant structure of the BSI-18 for both sexes. The BSI-18 is a short instrument that can be used by researchers and health professionals to assess the psychological distress of cancer survivors.

Resumen El Inventario Breve de Síntomas-18 (BSI-18) es un instrumento de cribado ampliamente utilizado para evaluar distrés emocional (GSI) y tres tipos de síntomas: ansiedad, depresión, y somatización. Este trabajo estudia la estructura factorial del BSI-18, utilizando análisis factorial confirmatorio (AFC), su fiabilidad y validez convergente, así como su invarianza factorial a través del sexo. Una muestra de 1183 pacientes de cáncer completó el BSI 18 y la lista de problemas de la NCCN. Los modelos jerárquicos de tres y cuatro factores proporcionaron ajustes adecuados y similares. Sin embargo, el modelo de tres factores (propuesta teórica) fue seleccionado por razones metodológicas y teóricas. Los índices de fiabilidad (alfa de Cronbach y fiabilidad compuesta) fueron satisfactorios y las correlaciones positivas y significativas entre el BSI-18 (GSI y subescalas) y las categorías emocionales y físicas del listado de problemas evidenciaron la adecuada validez convergente del instrumento. Finalmente, el AFC multigrupo reveló una estructura básicamente invariante del BSI-18 a través del sexo. El BSI-18 es un instrumento breve que puede ser utilizado por investigadores y profesionales de la salud para evaluar el malestar psicológico en la población con cáncer.
