RESUMEN

OBJECTIVE: This study evaluates the effectiveness of an intervention mapping developed to promote fruit and vegetable consumption. DESIGN: Students (n = 394) from two similar public colleges in the Quebec City area (Canada) were asked to participate. A quasi-experimental design was used with a 14-week pause between the pretest and posttest. The control and experimental groups both received information on Canada's Food Guide recommendations. The experimental group was submitted to an intervention consisting of six interactive workshops carried out inside the college, and three personal exercises to be completed at home. MAIN OUTCOME: proportion of respondents consuming at least five servings of fruits and vegetables daily. SECONDARY OUTCOMES: psychosocial variables assessed (theory of planned behaviour). RESULTS: The data collected from 344 participants by means of a self-administered questionnaire were analysed (167 experimental and 177 control). The posttest revealed a significant increase (15%) in the number of participants in the experimental group achieving the primary outcome (d = .38). The intervention also had a significant effect on the targeted psychosocial variables (η(2) = .03 to .06). Regularity of consumption acts as a mediator between intention and behaviour. CONCLUSION: These results may be used to guide health promoters working with college students.

RESUMEN

AIMS: Using an extended theory of planned behaviour, this article is a report of a study to identify the factors that influence nurses' intention to integrate research evidence into their clinical decision-making. BACKGROUND: Health professionals are increasingly asked to adopt evidence-based practice. The integration of research evidence in nurses' clinical decision-making would have an important impact on the quality of care provided for patients. Despite evidence supporting this practice and the availability of high quality research in the field of nursing, the gap between research and practice is still present. DESIGN: A predictive correlational study. METHODS: A total of 336 nurses working in a university hospital participated in this research. Data were collected in February and March 2008 by means of a questionnaire based on an extension of the theory of planned behaviour. Descriptive statistics of the model variables, Pearson correlations between all the variables and multiple linear regression analysis were performed. RESULTS/FINDINGS: Nurses' intention to integrate research findings into clinical decision-making can be predicted by moral norm, normative beliefs, perceived behavioural control and past behaviour. The moral norm is the most important predictor. Overall, the final model explains 70% of the variance in nurses' intention. CONCLUSION: The present study supports the use of an extended psychosocial theory for identifying the determinants of nurses' intention to integrate research evidence into their clinical decision-making. Interventions that focus on increasing nurses' perceptions that using research is their responsibility for ensuring good patient care and providing a supportive environment could promote an evidence-based nursing practice.

RESUMEN

PROBLEM: Despite the recognition by nurses of the importance of supporting their experiential knowledge on scientific data, evidence-based nursing research is seldom integrated in their practice. An important limitation is the nurses' general lack of basic abilities to use research to better inform their clinical decision making. The objective of this pilot study was to evaluate a leader training intervention on research results integration in nursing practice. INTERVENTION: Seven advanced practice nurses and 12 clinical nurses from six care specialties jointly participated to training activities on knowledge transfer and exchange. METHOD: Nineteen nurses went through a 20-day training internship and 14 participated to two interviews, before and after the intervention. RESULTS AND CONCLUSION: Overall, nurses were very positive about their participation to the training. Difficulties encountered during the internship and the prior negative perception about the research process, were largely offset by the acquired capabilities and the clinical results of the intervention. Furthermore, the beginning of change in the organization and in relations with some health professionals were noted and seen as positive.

RESUMEN

Faced with the abundance of available literature, clinicians must follow a method in order to carry out a critical reading of scientific articles. This enables them to decide how relevant the selected article is to the issues specific to their area of work and to choose whether to undertake a basic critical reading or to embark on an active reading.

RESUMEN

BACKGROUND: Skin and soft-tissue infections are very common among persons who inject drugs. They occur when microbes pass under the protective layer of the skin and proliferate. This happens when harm reduction recommendations such as skin aseptia before injection and sterile injection equipment usage are not properly followed. METHODS: A group of active drug users involved in a health promotion project as peer educators were asked about their formation needs. To address their inquiries concerning skin and soft-tissue infections, we devised with them a series of workshops touching upon common infections, the microflora, and microbial transmission. RESULTS: Participants learned to identify common infections and how to properly react in case of an abscess, cellulitis or phlebitis. They saw microscopic objects, found out about the high prevalence of microbes in their environment and on their skin, and could appreciate the efficiency of different washing and disinfection techniques. They visualized how easily microbes can spread from person to person and from contaminated objects to persons. CONCLUSION: In the weeks following this activity, some participants demonstrated and reported healthy behavioural changes regarding their own injection practices. Furthermore, they shared their newfound knowledge and began enforcing its application among people they inject drugs with. Most participants greatly appreciated this activity and valued it as being highly efficient and tangible.

RESUMEN

This study was an evaluation of a safe sex promotion programme in gay bars, saunas and sex shops in Québec City. The impact of the intervention on safe sex was assessed by means of an interrupted sequential pre-interventions and post-interventions quasi-experimental design with independent samples. At each measurement time, approximately 320 individuals were recruited in gay bars and saunas and were invited to complete a self-administered questionnaire. The intervention had a significant impact on safe sex mainly among the 18-29 age group (relative risk = 0.71; 95% confidence interval [CI95%] = 0.55-0.92), even after controlling for the effect of gay venue frequentation. Thus, the effect size of the intervention corresponds to a significant reduction of 29% in risky unprotected anal sex among this age group. Implementation of a theory-based community-level intervention has a positive impact on reducing unsafe sex practices, particularly among the 18-29 age group. However, if the preventive activities are not maintained on a regular basis, there is recrudescence in unsafe sex practices.

RESUMEN

This study reports the evaluation of an intervention designed to reinforce tobacco abstinence among elementary schoolchildren in a school transition period. This intervention was developed according to the principles of Intervention Mapping. A total of 765 grade 5 students (ages 10-12) was recruited in 32 elementary schools. A quasi-experimental longitudinal design was used to evaluate the outcomes. Results observed 2 and 8 months postintervention are reported here. It is shown that although the behavior remained largely unchanged by the intervention, some of its determinants were modified. Behavioral intention, behavioral and normative beliefs, perceived self-efficacy, and role beliefs were changed at one or both postintervention measures. An interesting feature of these results relates to the fact that the most positive outcomes were seen among at-risk children. Discussion considers the advisability to develop, implement, and evaluate evidence-based interventions targeting the psychosocial factors underlying maintenance of tobacco smoking abstinence in elementary school.

RESUMEN

BACKGROUND: Despite the progress made in smoking prevention among youth, few scientific reports have identified the determinants underlying the abstinence from cigarettes, and even fewer have made an assessment of their evolution over time. It has been proposed that this could be done by modeling after theoretical frameworks. METHODS: A self-reported questionnaire developed according to Ajzen's Theory of Planned Behavior was repeatedly administered to a cohort of 373 grade 5 students (191 girls and 182 boys) during their transition from elementary to secondary school. Four measures spanning a 26-month period were thus obtained and analyzed according to the GEE method. RESULTS: After 26 months, 76.14% of the students in the sample remained abstinent from cigarettes. The perceived smoking behaviors of friends and of a brother, intention over time, perceived self-efficacy, parental supervision, and socioeconomic status predicted the maintenance of abstinence from smoking. The final predictive model had a sensitivity of 79.8% and a specificity of 75.6%, with an average rate of accurate classification of 79.1%. CONCLUSIONS: The predictive model yielded by this study represents an important step toward developing tools to help 10-12 years olds maintaining their abstinent behavior. It emphasizes positive protective factors and guides health promoters in the choice of their interventions' contents and targets.
