RESUMO
This article presents a systematic review of the literature concerning scientific publications on wrist wearables that can help to identify stress levels. The study is part of a research project aimed at modeling a stress surveillance system and providing coping recommendations. The investigation followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. In total, 38 articles were selected for full reading, and 10 articles were selected owing to their alignment with the study proposal. The types of technologies used in the research stand out amongst our main results after analyzing the articles. It is noteworthy that stress assessments are still based on standardized questionnaires, completed by the participants. The main biomarkers collected by the devices used in the selected works included: heart rate variation, cortisol analysis, skin conductance, body temperature, and blood volume at the wrist. This study concludes that developing a wrist wearable for stress identification using physiological and chemical sensors is challenging but possible and applicable.

O objetivo do estudo foi adaptar e validar o Questionnaire on Resources and Stress-Short Form (QRS-F), desenvolvido para medir o estresse de pais de crianças com transtornos do desenvolvimento (TD), criando uma versão para a população brasileira, o Questionário de Estresse para Pais de Crianças com Transtornos do Desenvolvimento (QE-PTD). Participaram do estudo 360 pais de crianças com (TD), com idade média de 32,13 anos (DP = 8,19), sendo 65,6% crianças com paralisia cerebral. Após a análise fatorial o resultado, foi o QE-PTD com 32 itens e quatro fatores (Fator I: Incapacidades da Criança; Fator II: Problemas Familiares; Fator III: Restrições Comportamentais; Fator IV: Sobrecarga Emocional). Os quatro fatores explicam 46% da variância com Kuder-Richardson 20 de 0,88 para a escala total. O QE-PTD mostrou correlações moderadas com o Questionário de Saúde Geral e com o Inventário Beck de Depressão. Os resultados mostram índices de confiabilidade e validade satisfatórios. (AU)
The aim of the study was to adapt and validate the Questionnaire on Resources and Stress-Short Form (QRS-F), developed to assess the stress of parents of children with developmental disorders (DD), creating a version for the Brazilian population, the Questionnaire of Stress for Parents of Children with Developmental Disorders (QE-PTD). Study participants were 360 parents of children with DD, with a mean age of 32.13 years (SD = 8.19), 65.6% of whom had children with cerebral palsy. Through factor analysis, the QE-PTD was found to have 32 items and four factors (Factor I: Child's Disabilities; Factor II: Family Problems; Factor III: Behavioral Restrictions; and Factor IV: Emotional Overload). The four factors explained 46% of the variance with a Kuder-Richardson formula 20 value of .88 for the total scale. The QE-PTD presented moderate correlations with the General Health Questionnaire and the Beck Depression Inventory. The results obtained showed satisfactory reliability and validation indices. (AU)

La identificación de niveles de estrés en pacientes diabéticos tiene implicancias clínicas y prácticas. En Chile no hay escalas válidas y confiables que midan estrés en pacientes diabéticos. Con el objetivo de estimar las propiedades psicométricas de la Escala de estrés para diabéticos de Polonsky et al. (2005) en una muestra de pacientes diabéticos chilenos, se realizó análisis de confiabilidad, análisis factorial exploratorio y correlaciones con la escala de síntomas depresivos (CES-D) y con el marcador fisiológico hemoglobina glicosilada (HbA1c), en una muestra de 76 pacientes diabéticos tipo 2 de la ciudad de Temuco, Chile. Tras los análisis, se estimó una consistencia interna de 0.74, una estructura de 4 subfactores y evidencia de validez convergente con la escala CES-D y HbA1c. La escala de estrés para diabéticos posee propiedades psicométricas adecuadas, permite la identificación de 4 subfactores y es de fácil aplicación en el campo clínico e investigativo.
The measurement of stress levels in type 2 diabetic patients has clinical and practical meaning. In Chile, there is a lack of reliable and valid scales that allow for the right assessment of stress level among diabetic patients. The study purpose was to determine the psychometric properties of the Diabetes Distress Scale (DDS) in a sample of Type 2 Chilean diabetic patients. Several analyses including reliability analysis, exploratory factor analysis, and correlations with the depressive symptoms scale (CES-D), and the HbA1c biomarker were conducted with a Type 2 diabetic sample (n= 76) from Temuco City, Chile. The results provided a reliability of 0.74, a four-factor structure, and evidence for convergent validity with both the CES-D scale and the HbA1c marker. The DDS has acceptable psychometrics properties. It allows for the assessment of 4 factors, and has as advantage to be easy to apply in both clinical and research settings.
