Translation and Validation for the Portuguese Adult Population of the Persistent and Intrusive Negative Thoughts Scale: Assessing Measurement Invariance

Abstract

Repetitive Negative Thinking (RNT) is a transdiagnostic construct associated with a variety of emotional disorders. To date, disorder-specific self-report measures have been found to capture specific types of RNT. The Persistent and Intrusive Negative Thoughts Scale (PINTS) is a 5-item measure developed to overcome current limitations. The current study aims to translate and validate the PINTS for the Portuguese population. An online sample consisting of 432 participants (213 men, 219 women) completed the PINTS and a series of related self-report measures. Confirmatory factor analysis revealed that the one-factor model fit the Portuguese version and supported the proposed factorial structure. Reliability analyses showed good internal consistency and excellent temporal stability. Convergent and criterion validity results also showed good values. Overall, the Portuguese version of the PINTS proved to be a brief and reliable measure for assessing persistent and intrusive negative thoughts, and its use in clinical and research contexts is recommended.

Rebellious yet apathetic: System justification and learned helplessness in collective action

“…Ademais, também foram corroboradosa os índices adequados de confiabilidade (precisão) da medida (a e w = 0,94), com seus valores ficando acima do ponto de corte de no mínimo 0,70 (Cohen et al, 2014;McDonald, 1999). Os resultados ratificam a estrutura unifatorial, como evidenciado em pesquisas prévias em diferentes países, como Austrália (Magson et al, 2019) e Portugal (Peixoto & Cunha, 2021).…”

“…Por fim, espera-se que contar com uma medida curta e de fácil aplicação possa auxiliar o profissional, visto que a investigação psicológica geralmente envolve o rastreio de múltiplas variáveis (Medeiros et al, 2023). Ademais, em contextos clínicos, para avaliar diagnósticos importantes e suas comorbidades, medidas reduzidas podem atenuar a sobrecarga de conteúdo que os instrumentos longos podem ocasionar, tanto para o paciente como para o terapeuta (Peixoto & Cunha, 2021). Por fim, contar com uma ferramenta que abrange diferentes faixas etárias pode ampliar o entendimento sobre o tema, uma vez que pesquisas em amostras com crianças e com adolescentes são escassas (Bijttebier et al, 2015).…”

Psychometric Properties of the Positive Thinking Skills Scale (PTSS) among Portuguese Adults

“…Persistent and Intrusive Negative Thoughts Scale (PINTS) [40]. The Portuguese version of the PINTS [41] was used. This self-report instrument aims to assess a thinking style characterized by persistent thoughts that are also intrusive and negative.…”
