Psychometric Properties and Measurement Invariance of the Herth Hope Index in Spanish Cancer Patients.

Background: The aim of this study was to evaluate the psychometric properties, differential item functioning, factorial invariance, and convergent validity of the Spanish version of the Herth Hope Index (HHI) in patients with cancer.

Method: Exploratory and confirmatory factor analyses were conducted to explore the scale, dimensionality, functioning of items, test for strong measurement invariance across sex, age, tumor site, and expected survival, and an extended structural equation model to assess external validity in a cross-sectional, multicenter, prospective study of 863 cancer patients from 15 Spanish hospitals.

Results: The results do not support the original 3-factor scale but instead suggest a one-factor structure, which explained 62% of the common variance.

Psychological factors and prognostic communication preferences in advanced cancer: multicentre study.

Objectives: Communication regarding prognosis to patients with advanced cancer is fundamental for informed medical decision making. Our objective was to analyse (1) the proportion of subjects with advanced cancer who prefer to know their prognosis, (2) the characteristics associated with patients' preference for prognostic information, (3) the psychological factors that impact the preference to know prognosis and 4) the concordance between preference for prognostic information perceived among physicians and patients.

Methods: A prospective, cross-sectional design was adopted.

Psychometric properties of the Spanish version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30).

Purpose: The aim of this study was to analyze the internal structure of the EORTC QLQ-C30, to examine the validity and normative data for cancer patients.

Method: Exploratory and Confirmatory factor analyses were conducted to explore the scale's dimensionality and test for strong measurement invariance across sex and tumor site. All the analyses were based on a multicenter cohort of 931 patients who completed the Brief Symptom Inventory (BSI-18) and the EORTC QLQ-C30.

Psychometric Properties of the PDRQ-9 in Cancer Patients: Patient-Doctor Relationship Questionnaire.

Background: The patient-doctor relationship is an important concept in health care. The aim of this study was to evaluate the psychometric properties, convergent validity, and factorial invariance of the Patient-Doctor Relationship Questionnaire (PDRQ-9).

Method: Confirmatory factor analysis was conducted to explore the scale's dimensionality and test for strong measurement invariance across sex, age, and tumor site in a prospective, multicenter cohort of 560 patients who completed the PDRQ-9, Health-related Quality of Life Questionnaire (EORTC-QLQ-C30), and Brief Symptom Inventory (BSI) scales.

Impact of Obesity on Quality of Life, Psychological Distress, and Coping on Patients with Colon Cancer.

Background: Despite the causal relationship between obesity and colon cancer being firmly established, the effect of obesity on the course of cancer calls for further elucidation. The objective of this study was to assess differences in clinical-pathological and psychosocial variables between obese and nonobese individuals with colon cancer.

Materials And Methods: This was a prospective, multicentric, observational study conducted from 2015-2018.

Multidimensional Scale of Perceived Social Support (MSPSS) in cancer patients: psychometric properties and measurement invariance.

Background: The aim of this study was to evaluate the psychometric properties, convergent validity, and factorial invariance of the Multidimensional Scale of Perceived Social Support (MSPSS) in cancer patients.

Method: Confirmatory factor analysis (CFA) was conducted to explore the scale's dimensionality and test for strong measurement invariance across sex and age in a cross-sectional, multicenter, prospective study. Patients completed the MSPSS and Satisfaction with Life Scale (SWLS).

Psychometric properties of Spanish version of the Mini-Mental Adjustment to Cancer Scale.

Background/objective: The aim of the study was to examine the factor structure and psychometric properties of the Spanish version of the Mini-Mental Adjustment to Cancer Scale (Mini-MAC) in a large sample of patients with non-metastatic, resected cancer.

Methods: Prospective, observational, multicenter study for which 914 patients were recruited from 15 Spanish hospitals. Exploratory and confirmatory factor analyses, validity and reliability analyses were conducted.

Effects of pessimism, depression, fatigue, and pain on functional health-related quality of life in patients with resected non-advanced breast cancer.

Introduction: The aim was to analyze the effects of pessimism, depression, fatigue, and pain on functional health-related quality of life (HRQoL) in patients with resected, non-advanced breast cancer.

Methods: A prospective, multicenter study was conducted in 440 breast cancer patients. They completed the Brief Symptom Inventory (BSI), the European Organization for Research and Treatment of Cancer QoL-Questionnaire-Core-30 (EORTC-QLQ-C30), and the Revised Life Orientation Test (LOT-R).

Racial/ethnic differences in the prevalence of internalizing symptoms: do Latin-American immigrant show more symptomatology than Spanish native-born adolescents?

This study mainly compared the prevalence of internalizing symptoms of 834 Spanish and 159 Latin-American immigrant adolescents. Participants completed self-report measures about depression, anxiety and somatic symptoms and a socio-demographic questionnaire. The results indicated that being Latin-American was associated with higher levels of depressive symptoms and being female was related to higher depressive and anxiety symptoms.
