Abstract

Na área da suicidologia, Shneidman propôs a Escala de Avaliação de Dor Psicológica - PPAS. O objetivo deste estudo foi identificar as propriedades psicométricas da PPAS, em adolescentes da população geral, com e sem ideação suicida. A amostra foi de 525 adolescentes, com idade entre 15 e 19 anos, de escolas públicas e privadas de Porto Alegre. Utilizou-se o Inventário de Depressão de Beck, a Escala de Desesperança de Beck, a Escala de Ideação Suicida de Beck e a PPAS. Quanto à fidedignidade, verificou-se um coeficiente de consistência interna de 0,55 (pIn the suicidology field, Shneidman proposed the Psychological Pain Assessment Scale - PPAS. The objective of this study was identifying the PPAS psychometric properties in adolescents with or without suicide ideation within the general population. The sample included 525 adolescents, aged 15 to 19, attending public and private schools of Porto Alegre, Brazil. Beck Depression Inventory, Beck Scale for Suicidal Ideation and PPAS were used. As to reliability, an internal consistency rate of 0.55 (p<0.001) was found and, as to temporal stability, the rate was 0.93 (p<0.001). As to discriminant validity, PPAS showed to be able of differentiating adolescents having and not having suicidal ideation; for convergent validity, a weak-to-moderate correlation was found; factorial validity suggested three dimensions. Findings showed further studies would be needed concerning PPAS, including those carried out with clinical populations, as ideal psychometric properties were not assessed.
