This study aimed to adapt and validate the Irrational Procrastination Scale (IPS) and Pure Procrastination Scale (PPS) for Brazilian Portuguese. Therefore, 2666 university students were invited to participate in the study (M = 26.08; SD = 6.6; 77% female). The factorial structures were analyzed through exploratory and confirmatory factor analyses. The validity was investigated through Pearson’s correlations between the subscales of the Academic Procrastination Questionnaire ─ Negative Consequences and DASS-21. The reliability of the scales and their factors were evaluated through Cronbach’s alpha. The results indicated a one-dimensional IPS structure and a three-factor solution with a higher-order factor for PPS. Significant correlations were found between the IPS and PPS with the other measurements, revealing concurrent and convergent validity for both scales. The instruments showed good internal consistency, with alphas ranging from 0.80 to 0.91.

RESUMOO hipotireoidismo subclínico (HS) já foi associado a aumento do risco cardiovascular. Na avaliação desse risco, a medida da espessura íntima-média (EIM) carotídea por ultra-sonografia é capaz de detectar alterações iniciais da aterosclerose. O objetivo deste estudo foi avaliar a EIM carotídea em pacientes com HS e sua associação com um provável aumento do risco cardiovascular. Não foi encontrada diferença significativa nas medidas da EIM das pacientes com HS e das controles. Os resultados encontrados nos dois grupos estudados foram, respectivamente: 0,573 ± 0,070 mm vs. 0,576 ± 0,068 mm para as caróti-das comuns (p= 0,904) e 0,602 ± 0,079 mm vs. 0,617 ± 0,102 mm para as bifurcações (p= 0,714). Mesmo após estratificação das pacientes de acordo com o TSH e com a presença ou não de auto-imunidade, a diferença entre os sub-grupos permaneceu sem significância estatística. As medidas da EIM nesses grupos nos sítios avaliados foram: TSH 4-8 mUI/L: 0,579 ± 0,070 mm e 0,586 ± 0,063 mm; TSH > 8 mUI/L: 0,569 ± 0,073 mm e 0,616 ± 0,091 mm; anti-TPO+: 0,585 ± 0,070 mm e 0,621 ± 0,085 mm; anti-TPO-: 0,554 ± 0,072 mm e 0,571 ± 0,066 mm. Também não houve diferença no lipidograma e nas dosagens de apoproteína B e de lipoproteína (a). Este fato sugere que o HS, quando leve, sem alterações metabólicas associadas, não promove aumento do risco cardiovascular. Subclinical hypothyroidism (SH) has been associated with an increased risk for coronary disease. Carotid intima-media thickness (IMT), as assessed by ultrasonography, is a precise marker of atherosclerotic changes and can be used as an endpoint for cardiovascular events. Aims of this study were to determine carotid IMT in a group of patients with SH and its possible association with an increase in cardiovascular risk. There were no significant differences in mean carotid IMT between patients and controls. Results of both groups were, respectively: common carotid arteries, 0.573 ± 0.070 mm and 0.576 ± 0.068 mm (p= 0.904); carotid bifurcation, 0.602 ± 0.079 mm and 0.617 ± 0.102 mm (p= 0.714). Similar results were obtained when analyzing subgroups with serum TSH < or > 8 mIU/L and with positive or negative titers of TPOAb. The mean carotid IMT in these subgroups were: TSH 4-8 mIU/L: 0.579 ± 0.070 mm and 0.586 ± 0.063 mm; TSH > 8 mIU/L: 0.569 ± 0.073 mm and 0.616 ± 0.091 mm; TPOAb+: 0.585 ± 0.070 mm and 0.621 ± 0.085 mm; TPOAb-: 0.554 ± 0.072 mm and 0.571 ± 0.066 mm. No differences in the lipid profile and in the apoprotein B and lipoprotein (a) levels between the groups were found. These findings suggest that mild SH with no related metabolic changes is not associated with an increase in cardiovascular risk, as assessed by carotid IMT.

INTRODUÇÃOA definição de incontinência urinária (IU) como qualquer perda involuntária de urina (no último ano ou mês) foi introduzida pela Internacional Continence Society, com o intuito de uniformizar os estudos epidemiológicos, atendendo a que até então o conceito de IU era variável e dependente das diferentes culturas, países, estilos de vida, género e idade. 1,2

This study compared children's and mothers’ digital media use and mothers’ mental health in two samples: one accessed before (Group 1; N = 257; M = 33.18 years; SD = 4.79) and the other accessed during (Group 2; N = 256; M = 33.51 years; SD = 4.96) the COVID‐19 pandemic in Brazil. Mothers of children up to 3 years old (Group 1: M = 17.95 months, SD = 9.85; Group 2: M = 16.48 months, SD = 10.15) answered an online survey. Bivariate analysis, factorial ANOVA tests, and multiple linear regression were performed. Results suggest that mothers’ and children's media use duration was higher during the pandemic only among children over 12 months. Mothers’ media use duration (β = .18) and mothers’ intention to offer media (β = .23) contributed to the explanation of children's media use duration (F(4, 474) = 16.81; p < .001; R2 = .12; R2 adjusted = .117). Higher mothers’ common mental disorders symptoms were also positively correlated to mothers’ intention to offer media to children both before and during the pandemic. Results suggest that interventions focusing on infants and toddlers screen time reduction should target maternal aspects such as mental health, maternal screen time, and intention to offer media, taking into account the mothers’ needs when planning these actions.
