- Assessing the psychometric properties and validating the Portuguese version of the INSPIRE measure of staff support for personal recovery in PortugalPublication . Silva, Manuela; Aluh, Deborah Oyine; Lourenço, Ana; Resende, Beatriz; Agostinho, Francisco; Rodrigues, João Bessa; Azenha, João Pedro; Lopes, João Revez; Ribeiro, Marta; Heitor, Maria João; Gago, Joaquim; Cardoso, GraçaBackground: The importance of mental health services that support a recovery-oriented approach is increasingly recognized, and measures that evaluate this practice and promote change over time are needed. The INSPIRE measure is a 27-item questionnaire designed to assess service users’ perceptions of the support received from health professionals in their personal recovery. This study aimed to validate the Portuguese version of INSPIRE and assess its psychometric properties as a measure of staff support for personal recovery. Methods: The questionnaire survey was conducted from October 2023 to February 2024. Service users completed the Portuguese version of INSPIRE, the Client Satisfaction Questionnaire (CSQ-8), and a demographic and clinical questionnaire. Internal consistency was assessed using Cronbach’s alpha and McDonald’s model-based Omega. Test-retest reliability was assessed through the intraclass correlation coefficient (ICC) and weighted kappa. Convergent validity was examined by assessing correlation with CSQ-8. Factor validity was evaluated using exploratory factor analysis (EFA), with confirmatory factor analysis (CFA) performed to test the fit of factor structures derived from the EFA. Results: The study included 165 participants from seven psychosocial rehabilitation units which primarily target persons with a severe mental illness. For test–retest evaluation, 52 participants completed the questionnaire a second time. Internal consistency was satisfactory across all subscales and dimensions of the Support subscale, except for the Identity domain, which had marginally acceptable values. INSPIRE demonstrated significant positive correlations with CSQ-8 scores, supporting its convergent validity. EFA identified five factors for the Support scale and one factor for the Relationship scale, explaining 62% and 59% of the cumulative variance, respectively. CFA confirmed a good model fit for the Relationship scale and all Support subscales, except for the Identity and Empowerment subscales. Conclusions: The Portuguese version of INSPIRE showed strong internal consistency, as well as convergent and factor validity. This validated instrument can be applied in research and clinical settings to assess staff support for personal recovery and promote recovery-oriented mental health practices. Clinical trial number: Not applicable.
- Is Listeria innocua 2030c, a tetracycline-resistant strain, a suitable marker for replacing L. monocytogenes in challenge studies with cold-smoked fish?Publication . Vaz-Velho, Manuela; Fonseca, Fátima; Silva, Manuela; Gibbs, PaulThe suitability of Listeria innocua 2030c, a tetracycline-resistant strain, to be used as an indicator for replacing Listeria monocytogenes in challenge studies with cold-smoked fish was ascertained. L. innocua 2030c was compared to serovars 4b and 1/2c of L. monocytogenes, the major types isolated from Portuguese cold-smoked fish products. Growth curves at 30°C, growth/survival patterns at 30°C under exposure to different times and concentrations of ozone and sensitivity to Carnobacterium divergens V41 and C. piscicola V1 and their bacteriocins V41 and V1, were determined. No important differences between L. innocua 2030c and L. monocytogenes 4b and 1/2c were found, therefore L. innocua 2030c can be considered a suitable indicator for replacing those L. monocytogenes strains in challenge studies. Author Keywords: Carnobacterium spp.; Listeria spp.; Ozone
- Parents attending to nurse visits and birth age contribute to infant development: A study about the determinants of infant developmentPublication . Soares, Hélia; Barbieri-Figueiredo, Maria; Pereira, Sandra; Silva, Manuela; Fuertes, MarinaLife experiences and parenting play an important role in infant development. To prevent developmental risks and support parents in their educational role, it is important to identify the determinants of infant development. In this study, we investigate the association between child, maternal, family and social variables, and infant development, as well as we investigate the determinants of infant development. A sample of 86 healthy infants and their mothers participated in this study. At 11-months, infant development was assessed with Schedule of Growing Skills II (SGSII). To assess mother-infant quality of interaction, the dyads were observed in free play at 12-months using CARE-Index. Maternal sensitivity and infant cooperative behavior were correlated with SGSII global scores and sub-scales. Infant development was associated with maternal years of education, number of siblings, birth weight or risks in pregnancy. Number of nurse visits attended by parents during the infant first year and birth age were determinants of infant development.
