Translation and adaptation of the indoor environmental quality questionnaire to Brazilian portuguese

Introduction: Indoor environmental quality (IEQ) impacts well-being, performance, and mental and physical health. A questionnaire for assessing occupants' perception of IEQ was developed in English. This study aimed to translate this instrument into Brazilian Portuguese and adapt it to the Brazilian population.Methods: The translation and adaptation process consisted of forward translation, reconciliation, back translation, back translation review, harmonization, two cognitive debriefings, and finalization.Results: The final translated version included new questions and changed the scale to a visual-analog format. The clarity assessment showed that, after cognitive debriefings, all questions displayed satisfactory scores, with the majority rated higher than 9 on a 0-10 scale.Conclusions: The Brazilian Portuguese version of the IEQ questionnaire is a simple tool that can be employed in biomedical and building research to investigate the association of perceived IEQ with health-related parameters, as well as in architecture, engineering, and management projects. As a next step, a psychometric validation of the instrument will be performed.

Thirteen Reasons Why: The impact of suicide portrayal on adolescents' mental health.

We aimed to investigate the influence of media portrayals of suicide on adolescents' mood, focusing on the case of 13 Reasons Why, a webseries that raised concerns for approaching suicide explicitly for an audience mostly composed of adolescents. There is already evidence of an increase in suicide-related Internet searches shortly following its release. Our study included 7004 individuals aged 12-18 years. Participants were recruited through posts on 13 Reasons Why-themed social media groups. Volunteers filled an online questionnaire made available throughout May 2017 (54-71 days after the show was released). The questionnaire collected data on sociodemographic characteristics, mood (sadness and lack of motivation) in the month previous to watching the series, and prevalence of self-harm, suicidal ideation, or suicide attempts. Changes in mood were considered the main outcome; the variable was derived from a question asking about feelings of sadness and lack of motivation after watching the show. Overall, 23.7% reported worsening in mood after watching 13 Reasons Why. This rate was higher among individuals who, before watching the series, experienced more frequent and intense feelings of sadness and lack of motivation (OR 2.73 for frequent or daily feelings; OR 3.61 for intense feelings) or reported suicidal ideation/self-harm/suicide attempt (OR 1.38), even after controlling for sex and age. In times of easy access to digital content and binge-watching, the way mental health issues are portrayed in fiction needs to be carefully debated and thought out.

Spanish translation of the mood rhythm instrument: a novel approach to mood evaluation

Introduction: The Mood Rhythm Instrument (MRI) is a questionnaire developed to assess the circadian rhythm of mood-related behaviors. The aim of this study was to translate this instrument from Brazilian Portuguese into Spanish. Methods: The translation process consisted of forward translation, adjustment, back translation, back translation review and harmonization. Results: Comparing the initial Spanish translation and the final Spanish version, there were no semantic differences and the items were not changed. Conclusions: The Spanish version of the MRI is ready to be tested in a Spanish population. In the future, assessing and comparing mood-related behaviors in transcultural studies will be possible(AU)

Mudança de fotoperíodo: proposta de modelo experimental / Change of photoperiod: proposal for an experimental model

Introduction: There are some physiological and behavioral variations related to seasonality, and light is the major synchronizer of these variations according to the seasonal functions in temperate latitudes. Thus, the objective of this study was to validate a methodology for photoperiod modification in Wistar rats byevaluating its interference in the biological rhythm. Methods: Three male adult Wistar rats (60 days) were exposed to 3 photoperiods of 17 days each, with different light/dark cycles (LD): LDPP/SDPP Animal, exposed to initial LD 16:30/07:30 (LDPP, long-day photoperiod) and final LD 07:30/16:30 (SDPP, short-day photoperiod); SDPP/LDPP Animal, exposed to initial LD 07:30/16:30 and final LD 16:30/07:30; and final LD 16:30/07:30; and CT Animal, under constant LD 12:00/12:00. LDPP/SDPP and SDPP/LDPP animals underwent an intermediate photoperiod between initial and final LD, in which light exposure was increased or reduced by 30 min each day until the photoperiods were inverted. All animals remained isolated during the study and had their core temperatures continuously measured by sensors implanted in the peritoneal cavity and their locomotive activity assessed by sensors attached to their cages. The data obtained were used to construct histograms. Results: LDPP/SDPP and SDPP/LDPP animals had a longer period of activity in the SDPP than in the LDPP. The temperature of the CT animal followed a rhythmic pattern. The rat strain used was sensitive to changes in photoperiod. Conclusions: The model proposed and validated in this study can be used in experiments that aim to assess the consequences of changes in light exposure.

Introdução: Existem variações fisiológicas e comportamentais relacionadas à sazonalidade, e a luz é o principal sincronizador destas variações de acordo com as funções sazonais em latitudes de climas temperados. Sendo assim, o objetivo deste estudo foi validar uma metodologia de modificação de fotoperíodo com ratos Wistar avaliando sua interferência no ritmo biológico. Métodos: Três ratos Wistar machos adultos (60 dias) foram expostos a 3 fotoperíodos de 17 dias cada, com diferentes ciclos claro/escuro (light/dark, LD): Animal CL/CC, exposto a LD inicial 16:30/07:30 (CL, claro longo) e LD final 07:30/16:30 (CC, claro curto); Animal CC/CL, exposto a LD inicial 07:30/16:30 e LD final 16:30/07:30; e Animal CT, sob LD constante 12:00/12:00. Os animais CL/CC e CC/CL passaram por um fotoperíodo intermediário entre o LD inicial e final, no qual a exposição à luz foi aumentada ou diminuída em 30 min a cada dia até que os fotoperíodos se invertessem. Todos os animais permaneceram isolados durante o estudo e tiveram suas temperaturas corporais continuamente aferidas por sensores implantados na cavidade peritoneal e suas atividades locomotoras medidas por sensores acoplados às suas caixas. Os dados obtidos foram utilizados para construção de histogramas. Resultados: Os animais CL/CC e CC/CL apresentaram maior período de atividade em CC do que em CL. A temperatura do animal CT seguiu um padrão rítmico. A linhagem utilizada apresentou sensibilidade à mudança de fotoperíodo. Conclusão: O modelo proposto e validado neste estudo pode ser usado em experimentos que tenham como objetivo avaliar as consequências das mudanças de exposição à luz.
