Effectiveness of mobile applications as intervention tools in suicidal ideation: a systematic review and meta-analysis / Eficácia dos aplicativos móveis como ferramentas de intervenção na ideação suicida: uma revisão sistemática e meta-análise

Objective Evaluate the effectiveness of mobile applications developed for intervention in suicide risk in adults. Method Searches for articles were carried out in four databases (PubMed, Web of Science, Scopus and PsychINFO). For the meta-analyses, we used fixed effect modelling to assess the primary outcome. The PROSPERO register is CRD42020163876. Results After applying inclusion and exclusion criteria, six studies remained in the systematic review, of which four were eligible to the meta-analysis. There was no difference, or a little tendency in favor of control condition (usual treatment) comparing with applications. Conclusion Applications can be as effective as standard treatments in reducing suicide ideation. The results should be interpreted with caution once all studies presented at least one bias in their study design.

Para a meta-análise, utilizamos modelagem de efeito fixo para avaliar o desfecho primário. O registro no PROSPERO é CRD42020163876. Resultados Após aplicação dos critérios de inclusão e exclusão, seis estudos permaneceram na revisão sistemática, dos quais quatro foram elegíveis para a meta-análise. Não houve diferença, ou uma pequena tendência a favor da condição de controle (tratamento usual) em comparação com aplicativos. Conclusão Os aplicativos parecem ser tão eficazes quanto os tratamentos padrões na redução de ideação suicida. Os resultados devem ser interpretados com cautela, pois todos os estudos apresentaram viés em seu desenho.

A dimensional measure of schizotypy: cross-cultural adaptation and validation of the Oxford-Liverpool Inventory of Feelings and Experiences short version for Brazilian Portuguese (O-LIFE-S)

Abstract Introduction The Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE) is a widely-used scale, and the first to include a dimensional approach to understanding schizotypy. Objective To adapt the short version of the O-LIFE (O-LIFE-S) into Brazilian Portuguese. Method a) Two independent bilingual professionals translated the original instrument into Brazilian Portuguese; b) a third bilingual professional summarized the two translations; c) a fourth bilingual expert translated the Portuguese version back into English; d) this back-translation was adjusted by a committee of psychology experts; e) a pilot study was conducted with 10 participants from the general population. Results O-LIFE-S was considered ready to be used in a formal validation study in Brazil. Conclusion The scale appears to cover the dimensional approach to schizotypy. However, a future validation study needs to be conducted to determine the internal consistency and reliability of the Brazilian Portuguese version of the O-LIFE-S .
