The aim of the present study is to provide validation data regarding the Portuguese version of the Suicidal Behaviors Questionnaire Revised in nonclinical individuals. Two studies were undertaken with two different nonclinical samples in order to demonstrate reliability, concurrent, predictive, and construct validity, and in order to establish an appropriate cut-score for nonclinical individuals. A sample of 810 community adults participated in Study 1. Results from this study provided information regarding scale internal consistency, exploratory and confirmatory factor analysis, and concurrent validity. Receiver operating characteristic curve analysis established a cut-off score to be used for screening purposes with nonclinical individuals. A sample of 440 young adults participated in Study 2, which demonstrated scale score internal consistency and 5-month predictive validity. Further, 5-month test-retest reliability was also evaluated and the correlations of SBQ-R scale scores with two other measures that assess constructs related to suicidality, depression and psychache, were also performed. In addition, confirmatory factor analysis was undertaken to demonstrate the robustness of the result obtained in Study 1. Overall, findings supported the psychometric appropriateness of the Portuguese Suicidal Behaviors Questionnaire-Revise

A cooperação apresenta-se como a base de qualquer organização, mas também das equipas desportivas. O comportamento cooperativo é influenciado pela estima e confiança que o indivíduo tem em si. A confiança entre os indivíduos resulta da mediação entre o comportamento de interesse próprio e o interesse pelo outro, promovendo desta forma a cooperação entre os membros. Vários autores referem as noções de competência relacionadas com comportamentos de confiança. Desta forma estudaram-se no presente estudo as correlações entre a cooperação desportiva e o auto-conceito de competência. A amostra foi constituída por 120 atletas do sexo masculino de equipas profissionais e semi-profissionais de futebol. Os instrumentos utilizados "Questionário de Cooperação Desportiva" e "Questionário de Auto-Conceito de Competência", revelaram possuir qualidades psicométicas aceitáveis. A análise dos resultados revelou correlações estatisticamente significativas entre a dimensão de cooperação situacional e as dimensões, cognitiva, social e criativa do auto-conceito de competência, assim como a dimensão de cooperação incondicionada com as dimensões cognitiva e social do auto-conceito de competência. /ABSTRACT: The cooperation comes as the foundation of any organization but also of sports teams. The cooperative behavior is influenced by the esteem and confidence that the individual has in himself. Trust between individuals result of mediation between the behavior of self-interest and concern for others, thereby promoting cooperation among members. Several authors refer to the notions of competence-related behaviors of confidence. Thus it was studied in the present study the correlations between the sporting cooperation and self-concept of competence. The sample was composed of 120 male athletes of professional teams and semi-professional football. The instruments used "Cooperation Sports Questionnaire" and "Self-Concept Questionnaire for Competence," have revealed qualities psicométicas acceptable. The results showed statistically significant correlations between the dimension of cooperation and situational dimensions, cognitive, social and creative self-concept of ability, as well as the size of unconditional cooperation with the cognitive and social dimensions of self-concept of competence.

The aim of the present study is to test a theory-based model of suicide in a low-risk nonclinical sample. A community sample of convenience of 200 adults, 102 men and 98 women, responded to the Depressive Experiences Questionnaire, the Center for the Epidemiologic Studies of Depression Scale, the Psychache Scale, the Interpersonal Needs Questionnaire, and the Suicide Behaviors Questionnaire Revised. The hypothesized structural equation model, including trait dimensions of self-criticism and neediness, and state dimensions of depression, psychache, perceived burdensomeness, and thwarted belongingness, fit the observed data well and significantly explained 49% of the variance of suicidality.

Background: To implement appropriate programs for promoting physical activity (PA) in people who are Deaf, it is important to have valid instruments for assessing PA in this population. Objective: The main purpose of this study was to examine the criterion validity of the short form of the International Physical Activity Questionnaire (IPAQ-S) in Deaf adults. Method: This study included 44 adults (18e65 years) of both genders (63.6% were females) who met the inclusion criteria. Objective measures of PAwere collected using accelerometers, which were worn by each participant during one week. After using the accelerometer, the IPAQ-S was applied to assess participants’ physical activity during the last 7 days. Results: There was no significant correlation between the average time spent in moderate to vigorous physical activity (MVPA) as measured by the accelerometer (40.1 6 24.5 min/day) and by the IPAQ-S (41.3 6 57.5 min/day). The IPAQ-S significantly underestimated the time spent in sedentary behavior (7.6 6 2.7 h/day vs. 10.1 6 1.6 h/day). Sedentary behavior and MVPA as measured by the accelerometer and the IPAQ-S showed limited agreement. Conclusions: Our results show some limitations on the use of IPAQ-S for quantifying PA among adults who are Deaf. The IPAQ-S tends to overestimate the MVPA and to underestimate sedentary behavior in adults who are Deaf.
