[Instruments for assessing stress in Brazilians: an integrative review]. / Instrumentos de avaliação do estresse na população brasileira: uma revisão integrativa.

Introduction: Numerous instruments have been developed around the world to assess stress. This study aimed to identify instruments with validation studies that mapping stress in Brazil. Method: an integrative review was carried out on databases and the Testing System of the Federal Council of Psychology (SATEPSI) in June 2017 and updated this year. Two independent judges participated in analyzing the results. Results: Of the 6,377 articles, 47 articles were selected from the Index Psi, SciELO, LILACS and PubMed databases, and 35 instruments made up the sample, two of which were from SATEPSI. Nine of these tools map stress in a more general way, nine are aimed at specific clinical contexts, 12 are aimed at occupational stress, three at the sports context and another two at other contexts. Discussion: Numerous health problems are associated with early and chronic stressors, however it was identified that most instruments access stress in a more recent period of time (last year, month or week). A more accurate analysis of the relationships between longitudinal stress and health outcomes appears limited in this sense. The Stress and Adversity Inventory (STRAIN) appears as an alternative for studying stress throughout life in the Brazilian reality.

Weight loss interventions for overweight and obese adolescents: a systematic review.

PURPOSE: To determine what factors contribute to the efficacy of non-drug treatments designed to promote weight loss in overweight and obese adolescents. METHODS: Data sources Medline/PubMed; Psychinfo; EMBASE; Web of Science (ISI); and Cochrane Central Register of Controlled Trials. Study selection Randomized clinical trials of treatments for obesity and overweight in adolescents aged 10-19 years with a minimum duration of 2 months. Data extraction 115 of the 12,948 publications retrieved met eligibility criteria and 26 were included in the final sample. Period of extraction January 2004 to November 2014. RESULTS: The Delphi list was used to evaluate the methodological quality of the studies (M = 5.58, SD = 1.027). There was considerable variability between the interventions, but they were all multifactorial, with components such as nutritional education, physical activity, family support and psychological therapy. The number of contacts with subjects during the course of the intervention was a predictor of treatment efficacy when the groups were compared. Limitations This systematic review was limited to trials reported in English and by the lack of methodological rigor and shortcomings in reporting in the studies reviewed. CONCLUSIONS: Multidisciplinary interventions including family support and guided behavior modification appear to be effective methods of reducing BMI in overweight and obese adolescents.
