RESUMO
To determine the efficacy of the TTM to predict exercise behavior in a sample of Iranian college students. This was a cross-sectional study. Participants were 418 first year students of Guilan University of Medical Sciences who completed Iranian versions of the TTM and exercise behavior questionnaires. Data were analyzed using bivariate correlation and path analysis. In the final model, path coefficient for the processes of change [behavioral strategy], self-efficacy in exercise and pros were 0.54, 0.20 and -0.11 respectively. The model accounted for 38% of the variance for predicting current exercise behavior. The study findings support the application of TTM in exercise behavior changes among Iranian students
RESUMO
Behavioral Regulatin in Exercise Questionnaire-2 [BREQ-2] is the most commonly used tool for measurement of exercise behavior regulation. Measuring Instrument in every exercise study in order to obtain accurate research data should be cross-cultural validated. The purpose of this study is to assess the validity and reliability of the Iranian version of the BREQ-2 in a sample of university students. 418 students were recruited from Guilan university medical sciences for this cross sectional study. After translation, the validity of the instrument was assessed using content and construct validity [exploratory factor analysis]. The reliability of the BREQ-2 was assessed using Cronbach's Alpha for internal consistency. The Iranian version of the BREQ-2 was slightly modified to improve content validity. Factor analysis revealed that the adapted scale included four factors with acceptable Eigenvalues [alpha > 1.0], factor loadings [alpha > 0.4] and total variance explained [64%]. Study showed that BERQ-2 scales had acceptable internal consistency [alpha > 0.7]. The study concluded that BREQ-2 has acceptable validity and reliability in the Iranian population. Using BREQ-2 in similar studies is suggested to save time and costing

ComportamentoRESUMO
Coronary angiography is frequently applied for diagnostic purposes in patients with coronary artery disease. Be that as it may, there is still no consensus about the optimal time for the ambulation of patients following femoral arterial puncture. We sought to compare 6 hours of complete bed rest and 2 hours of complete bed rest in patients after angiography. This randomized quasi-experimental study was performed in 120 patients candidated for coronary angiography. The patients were divided into experimental and control groups randomly. Primarily demographic data were obtained from both groups before intervention was carried out for them. The arterial sheath was removed immediately after the procedure. Hemostasis was achieved by manual compression and maintained with sandbags. Early ambulation was attempted after two hours of supine bed rest following sheath removal. The incidence of bleeding and insertion site complications was documented at 24 hours and subsequently at 30 days post-procedure. Our findings were indicative of no significant difference between the two groups in terms of gender, age, body mass index, catheter size, total procedure duration, total hemostasis time, history of anticoagulant drug use, and coagulation tests before angiography. Pre-ambulation bleeding occurred in 2 patients in each of the two groups. Post-ambulation bleeding occurred in 2 patients in the control group and 1 in the experimental group. Whereas there was no incidence of large pre-ambulation hematoma in the control group, there was one case in the experimental group. There was no case of post-ambulation hematoma, however, in either group, and nor was there any late bleeding or vascular complication. Ambulation 2 hours after angiography via the femoral site is feasible and safe with the same incidence of insertion site complication as that of 6 hours of bed rest. Therefore, an early ambulation protocol can shorten hospital stay without significant vascular complications
