- Confirmatory factor analysis of the portuguese version of the Frost multidimensional perfectionism scalePublication . Carmo, Cláudia; Brás, Marta; Batista, Luis; Faisca, LuisThis study aimed to analyse the psychometric properties and dimensionality of the Portuguese version of the Multidimensional Scale of Frost Perfectionism (FMPS) using the confirmatory factor analysis. The sample consisted of 832 high school and college students (65.0% female) with a mean age of 19.5. The adjustment indexes of confirmatory factor analysis permitted to consider the multidimensional model of six factors the best representation of the data, replicating the original solution. The results showed good reliability and appropriate validity. The internal consistency of the scale presented satisfactory coefficients (Cronbach's alpha=.853). The test-retest method suggested a good temporal stability of the scale (r=.779). Globally the FMPS is a reliable and validated instrument for the study of perfectionism in Portugal.
- The volunteer functions inventory (VFI): Adaptation and psychometric properties among a portuguese sample of volunteersPublication . Martins, Cátia; da Silva, José Tomás; Jesus, Saúl; Ribeiro, Conceição; Estêvão, M. Dulce; Baptista, Ricardo; Carmo, Cláudia; Brás, Marta; Santos, Rita; Nunes, C.: The Volunteer Functions Inventory (VFI) is an instrument widely used to assess volunteers’ motivation based on the Functionalist Model of Omoto and Snyder. It assesses six factors that reflect several motivational functions. The VFI has been translated into various languages and validated in different cultural contexts, but some studies have reported different factor structures (e.g., five or four factors). In the Portuguese context, previous studies have also shown inconsistent results. The aim of this study was to adapt and validate the VFI for Portuguese volunteers, testing several alternative models (nine models) using confirmatory factor analysis. The sample comprised 468 volunteers (76.3% women), aged from 13 to 81 years (M = 36.66, SD = 14.93). The results support the original interrelated six-factor model as the best-fitting one. The VFI showed good internal consistency and convergent validity. Significant correlations were found between the VFI factors, organizational commitment, and volunteers’ satisfaction. Overall, the six-factor VFI is a valid and reliable tool for measuring the motivational functions of Portuguese volunteers, with implications for practice and research in the volunteering field.
- The psychometric properties of the positive and negative suicidal ideation scale among portuguese young adultsPublication . Brás, Marta; Antunes, João; Carmo, CláudiaPreventing suicide has been a worldwide imperative for the last decade. Accurately assessing suicide risk is the first step towards prevention, and access to reliable tools that measure risk factors is essential to achieve this goal. The Positive And Negative Suicidal Ideation (PANSI) scale is a validated brief suicidal ideation scale that could prove useful to this goal due to its ability to measure both suicide risk and protective factors. The PANSI scale has been adapted to various languages and cultures across various clinical and non-clinical populations. Despite this, no Portuguese has been produced yet. The present study aimed to validate a Portuguese version of PANSI by evaluating its psychometric properties in a sample of 259 young adults. Confirmatory factor analysis showed that the PANSI showed good psychometric properties (TLI = 0.95), good reliability for positive ideation (α = 0.84), and excellent reliability for negative ideation (α = 0.96). The scale also showed good discriminative ability through prediction of a previous suicide attempt and good construct validity in both subscales. The Portuguese adaptation of the PANSI scale is a reliable measure of positive and negative suicidal ideation that could prove useful in both clinical and research settings.
