    The abundance of scholarship on test development and use generally is higher in English-speaking than in Iberian Latin American countries. The purpose of this article is to help overcome this imbalance by describing and identifying similarities and differences in test development and use in two Iberian (Portugal and Spain) and three of the largest Latin American (Argentina, Brazil, and Venezuela) countries. The stages of test development in each country, roles of professional associations, presence of standards for test use, professionals’ educational training, commonly used tests, together with prominent challenges to continued progress are discussed. Test development and use in these five countries are transitioning from a dependence on the use of translated tests to greater reliance on adapted and finally nationally constructed tests. Continued growth requires adherence to international standards guiding test development and use. Stronger alliance among professional associations in the Iberian Latin American countries could serve as a catalyst to promote test development in these regions.A abundância de estudos sobre o desenvolvimento do teste e usar geralmente é maior em Inglês de língua do que nos países latino-americanos ibéricos. O objetivo deste artigo é ajudar a superar este desequilíbrio, descrever e identificar semelhanças e diferenças no desenvolvimento de testes e uso em dois Ibérica (Portugal e Espanha) e três dos maiores países da América Latina (Argentina, Brasil e Venezuela). Os estágios de desenvolvimento do teste em cada país, os papéis das associações profissionais, presença de padrões para uso de teste, a formação dos profissionais da educação, os testes comumente utilizados, juntamente com desafios importantes ao progresso continuado são discutidos. Desenvolvimento de testes e uso nestes cinco países estão em transição de uma dependência do uso de testes traduzidos para uma maior dependência de testes adaptados e finalmente construídos nacionalmente. O crescimento contínuo exige a adesão a padrões internacionais orientadores desenvolvimento de testes e uso. Aliança mais forte entre as associações profissionais dos países latino-americanos ibéricos poderia servir como um catalisador para promover o desenvolvimento do teste nessas regiões

    The Motivational Thought Frequency scales for increased physical activity and reduced high-energy snacking

    The Motivational Thought Frequency (MTF) Scale has previously demonstrated a coherent four-factor internal structure (Intensity, Incentives Imagery, Self-Efficacy Imagery, Availability) in control of alcohol and effective self-management of diabetes. The current research tested the factorial structure and concurrent associations of versions of the MTF for increasing physical activity (MTF-PA) and reducing high-energy snacks (MTF-S).Study 1 examined the internal structure of the MTF-PA and its concurrent relationship with retrospective reports of vigorous physical activity. Study 2 attempted to replicate these results, also testing the internal structure of the MTF-S and examining whether higher MTF-S scores were found in participants scoring more highly on a screening test for eating disorder.In Study 1, 626 participants completed the MTF-PA online and reported minutes of activity in the previous week. In Study 2, 313 participants undertook an online survey that also included the MTF-S and the Eating Attitudes Test (EAT-26).The studies replicated acceptable fit for the four-factor structure on the MTF-PA and MTF-S. Significant associations of the MTF-PA with recent vigorous activity and of the MTF-S with EAT-26 scores were seen, although associations were stronger in Study 1.Strong preliminary support for both the MTF-PA and MTF-S was obtained, although more data on their predictive validity are needed. Associations of the MTF-S with potential eating disorder illustrate that high scores may not always be beneficial to health maintenance
