Paranoia in the General Population : a revised version of the General Paranoia Scale for Adults

Background: Paranoid ideation has been regarded as a cognitive and a social process used as a defence against perceived threats. According to this perspective, paranoid ideation can be understood as a process extending across the normal-pathological continuum. Methods: In order to refine the construct of paranoid ideation and to validate a measure of paranoia, 906 Portuguese participants from the general population and 91 patients were administered the General Paranoia Scale (GPS), and two conceptual models (one - and tridimensional) were compared through confirmatory factor analysis (CFA). Results: Results from the CFA of the GPS confirmed a different model than the one-dimensional model proposed by Fenigstein and Vanable, which com-prised three dimensions (mistrust thoughts, persecutory ideas, and self-deprecation). This alternative model presented a better fit and increased sensitivity when compared with the one-dimensional model. Further data analysis of the scale revealed that the GPS is an adequate assessment tool for adults, with good psychometric characteristics and high internal consistency. Conclusion: The model proposed in the current work leads to further refinements and enrichment of the construct of paranoia in different populations, allowing the assessment of three dimensions of paranoia and the risk of clinical paranoia in a single measure for the general population.

Hazing practices in higher education : a study with portuguese students

Hazing practices in higher education institutions are perceived controversially. This study looked at the perception towards hazing practices of students from the University of the Azores in first cycle (n=247). It analyses if their perception was positive, emphasizing the integrative aspects of hazing practices, or if it was negative, inclining to define those practises like being violent and humiliating. The applied questionnaire measures 3 factors to define individual’s perception with hazing practices (positive relation with hazing practices, negative relation and the social dimension of the practices). This study used descriptive analyses to observe the level of agreement with hazing practices and non-parametrical statistical test to analyse the relationship between their levels of agreement with hazing practices and socio-demographic variables. Results emphasised balanced proportion of students perceiving positively and negatively those practices and incline to define hazing practices with the same components in both perceptions. It didnot highlight a strong mandatory integrative component in students’ perception. Also, results stressed a large part of students disinterested in hazing practices. Additionally factors of hazing practices’ perception showed significant relationships with respondent’s sex, age and academic degree. Hazing practices in this study did not seem to meet their main objectives of welcoming and integrating freshmen in higher education institutions.

Praxe académica : meio de integração ou ações de humilhação?

Esta investigação incidiu sobre o modo como estudantes de uma instituição portuguesa de ensino superior percecionam a praxe académica e situações de bullying na praxe. Os dados foram recolhidos através da escala de “Avaliação das situações de Bullying nas Praxes do Ensino Superior”, organizada em três fatores: Relação Positiva com a Praxe, Relação Negativa com a Praxe e Dimensão Social (Matos, Jesus, Simões & Nave,2010). Participaram no estudo 247 estudantes de ambos os sexos, entre os 18 e os 43 anos, de diferentes anos, cursos e departamentos. Os resultados indicaram diferenças significativas a nível da Relação Positiva com a Praxe entre o género (masculino e o feminino; p=0.001 < α=0.05) e entre faixas etárias (“20 ou menos anos” e com “mais de 20 anos”; p=0.024 < α=0.05). Permitiram, também, observar diferenças significativas entre os anos dos cursos (1º, 2º ou 3º ano) a nível da Relação Positiva com a Praxe (p=0.04 < α=0.05) e da Dimensão Social (p=0.017 < α=0.05). Finalmente indicaram diferenças significativas entre os departamentos de pertença dos alunos no que concerne à Relação Positiva com a Praxe (p=0.02 < α=0.05) e à Relação Negativa com a Praxe (p=0.02 < α=0.05). As correlações obtidas entre os três apresentaram-se estatisticamente significativas, considerando nível de significância de 1% (respetivamente, p=0.02; p=0.00 e p=0.00).
