Aim:To verify whether nursing personnel working at a general hospital change their attitudes after a brief training course on suicide prevention and if these newly acquired attitudes persist over a 6-month time.Method:317 nursing personnel attended a 6-hour training program. They answered anonymously pre- and post-training the Suicide Behavior Attitude Questionnaire (SBAQ) which comprises 21 visual analogue scale items divided in three factorial sub-scales. The scores on each SBAQ sub-scale (dependent variable) were compared along the time using ANOVA for repeated measures with rank transformation. The time of the measurement and characteristics of the nursing staff were considered as independent variables.Results:There have been positive changes in the attitudes and these gains were significantly maintained at the 6-month follow-up evaluation. Improvement was in the Feelings and Professional Capacity factorial subscales (p = 0.0001 and 0.01, respectively). There was no change on the Right to Suicide subscale.Conclusion:It was possible to demonstrate positive changes in the attitudes of nursing personnel as assessed six months after a brief training course on suicide prevention. As attitudes influence the effectiveness of the health care personnel interventions our findings may have important implications for the development of suicide prevention programs.
In this article two new MAC protocols for wireless sensor networks based on TDMA (Time Division Multiple Access) access method are proposed. The proposed protocols are convenient for applications demanding a small number of sensors highly concentrated in a small region, such as in medical areas. The main characteristic of the proposed protocols is the simplified access scheduling that guarantees a low energy consumption and a reduced overhead. The energy consumption of the proposed protocols are estimated analytically and compared to the consumption of the protocols known in the literature. Also a simplified analysis of messages transference delay of proposed protocols is calculated. The results show that the energy consumption of the proposed protocols, in certain conditions, are smaller than other compared protocols. messages transference delay are relatively small and proposed protocols are more adjusted for transference of messages simultaneous.
