ABSTRACT
Introduction: Suicide is a preventable death in young people. It is well known that suicide behavior is a multicausal phenomenon. However, suicidal ideation (SI) commonly underlies suicide, and Ecological Momentary Assessment (EMA) can help us to better characterize it and its risk and protective factors in the short term. We aimed, first, to investigate the estimated prevalence and trajectories of SI in a community sample of Spanish college students using an EMA methodology and, second, explore the associations between risk and protective factors and SI categorized as moderate or low. Materials and Methods: A total of 737 participants followed the EMA during a period of 6 months. We estimated the prevalence and trajectories of SI and the associations between depressive symptoms, positive and negative affect, thwarted belongingness, perceived burdensomeness, cognitive reappraisal, emotional suppression, and purpose in life with the MEmind smartphone App. SI was assessed 14 times during this period. Results: Twenty-eight participants referred to SI at least once in longitudinal assessments. We found a lack of curvature and, thus, a relatively stable trajectory of SI. Two groups of latent dimensions were observed related to risk and protective factors of SI. One latent dimension of the risk factors (higher levels of thwarted belongingness, perceived burdensomeness, depressive symptoms, negative affect, and emotional suppression) best represented the group with moderate levels of SI, and a second latent dimension of protective variables (positive affect, cognitive reappraisal, and purpose in life) best represented the group with lower levels of SI. Discussion: These findings may indicate that students with a sense of having a life worth living, in addition to having the ability to reevaluate their negative beliefs, are less likely to experience high levels of SI. Therefore, purpose in life would be a protective factor against the presence of SI.
ABSTRACT
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.

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.
