Conversion of extrinsic into intrinsic motivation and computer based testing (CBT).

BACKGROUND: Because computers are used in many aspects of today's life, it seems necessary to include them in teaching and assessment processes. METHOD: The aims of this cross-sectional study were to construct a multidimensional valid scale, to identify the factors that influenced the nature of student motivation on Computer Based Testing (CBT), to recognize how students self-regulated their activities around CBT, and to describe the efficiency of autonomous versus controlled situations on motivation. The study was carried out among 246 Iranian Paramedical Students of Tabriz Medical Sciences University, Tabriz, Iran; 2013-2014. The researchers prepared a questionnaire, based on the Self-Determination Theory (SDT), containing 26 items with a five-point Likert scale. It was prepared according to a previous valid questionnaire and by sharing opinions with some students and five professors. The factor analysis was done to perform instructional and exploratory factor analysis. RESULTS: The Kaiser-Meyer-Olkin(KMO) measure was performed and variables were correlated highly enough to provide a reasonable basis for factor analysis. The selected 4 factors determined a 60.28% of the variance; autonomy 26.37%, stimulation 14.11%, relatedness10.71%, and competency 9.10%. CONCLUSION: A questionnaire was prepared and validated, based on SDT variables. The results indicated that autonomous extrinsic motivation correlated positively with intrinsic motivation and CBT. There was a general positive attitude towards computer-based testing among students. As students became intrinsically motivated through the promotion of autonomous regulation, CBT was recommended as a proper test mode.

HIV, HCV, HBV, HSV, and syphilis prevalence among female sex workers in Tehran, Iran, by using respondent-driven sampling.

To find out the prevalence of HIV, HCV, HBV, HSV, and syphilis infections among female sex workers (FSWs) in Tehran, a cross-sectional study by using respondent-driven sampling (RDS) method was conducted. From December 2012 to April 2013 FSWs in Tehran were recruited. Inclusion criteria consisted of trading sex during the 12 months prior to this study and selling sex for at least 6 months in participants' lifetime. Among 161 consenting participants, 5% were infected with HIV. Moreover, 8.1% of FSWs were HCV positive, 37.9% were of HSV type1/type2, 1.2% of participants were infected with HBV, and none of the participants were infected with syphilis. HIV-positive participants were significantly more likely to be co-infected with HSV type1/type2, be younger, have more sexual partners and especially more clients during seven days prior to this study and report more history of having at least one of sexually transmitted infections symptoms in 12 months prior the study. In the multiple logistic regression analysis, being infected with HSV and also being under 25 years of age were found to be independently associated with HIV infection. Compared with the prevalence of HIV among general population of Tehran, relatively high prevalence of HIV and other viral infections among FSWs should be considered. All in all, it is critical to commence effective counter-measures for this high-risk group if the aim is to prevent spreading of these viruses to general population.
