Abstract
The purpose of the present study was to examine the reliability, factorial validity and measurement invariance (across gender, age and physical activity participation) of a Portuguese version of the Rosenberg Self-Esteem Scale (RSES). The sample consisted of 1,763 Portuguese youngsters (731 male and 1,032 female) with ages between 15 and 20 years. Reliability estimate for the one-factor solution was .845, although some proposed RSES's underlying dimensions were lower than .70. Confirmatory factor analysis revealed that the best-fitting model was a single self-esteem factor, plus simultaneous correlated uniqueness for positively and negatively worded items. Multigroup analysis supported measurement invariance across age and physical activity participation, and partial metric invariance across gender, as three items failed to show metric equivalence. These results provide evidence that RSES has excellent psychometric properties and it is a valid self-esteem measure to be used among Portuguese youngsters.

Abstract
Objectives: The purposes of the present study were to assess the factorial structure and reliability of the Greene Climacteric Scale (GCS), and provide normative data for a sample of postmenopausal Portuguese women. Methods: A sample of 401 Caucasian women, with ages between 47 and 91 years, divided into four age groups (47-57: 31.4%, 58-68: 40.4%, 69-79: 21.4% and >= 80: 6.7%), voluntarily participated in the study. The Greene Climacteric Scale aims to measure psychological symptoms divided into anxiety and depression, somatic and vasomotor symptoms with a total of 21 items. Data were analyzed by reliability, correlation and confirmatory factor analyses. Age group differences in the raw and the standardized scores of symptoms clusters were investigated by means of ANOVA procedures. Results: The CFA performed supported the 4-factor structure specified by Greene (*CFI = 0.937; SRMR = 0.046; *RMSEA (90%IC) = 0.050 (0.042-0.058). The computed internal consistency estimates ranged from 0.73 to 0.90. Vasomotor symptoms (hot flushes and sweating at night) were experienced most frequently by the younger age group (47-57 years) while nonspecific symptoms (e.g. difficulty in concentrating, feeling tired or lacking in energy, breathing difficulties) were reported more frequently by the older age groups. Conclusions: Our results suggest that the Portuguese version of the GCS is a reliable and a valid instrument for the measurement of climacteric-related factors in postmenopausal women.

Abstract
The aim of this work was to study the impact of the implementation of a mental training program on swimmers' chronometric performance, with national and international Portuguese swimmers, based on the goal setting model proposed by Vasconcelos-Raposo (2001). This longitudinal study comprised a sample of nine swimmers (four male and five female) aged between fourteen and twenty, with five to eleven years of competitive experience. All swimmers were submitted to an evaluation system during two years. The first season involved the implementation of the goal setting model, and the second season was only evaluation, totaling seven assessments over the two years. The main results showed a significant improvement in chronometric performance during psychological intervention, followed by a reduction in swimmers' performance in the second season, when there was no interference from the investigators (follow-up).

Abstract
This research aims to investigate the level of knowledge of the population of Mozambique Island about malaria, one of the diseases that most affect the country. Against this background we have developed an exploratory study, constituted by a sample of 500 individuals of both sexes, residing in different districts of the island. Overall, the respondents are mostly well informed about the characteristics of the disease, its implications, and ways of prevention. Still, the Island has residents without information about malaria. These people, who have a low level of knowledge about the disease, although in smaller numbers, still perform little preventive procedures and contribute to the increase in cases of this disease. It is considered that the results of this study are a contribution to the definition of priority actions in the promotion of education and health, specifically with regard to malaria.
