The nurses in the study had a positive experience with motivational interviewing, which can contribute to the increased use, adaption and development of motivational interviewing among primary healthcare professionals. Increased motivational interviewing knowledge and skills would also contribute to promotion of health lifestyle practices.
Objective: This study evaluated changes in self-efficacy in non-physically active adolescent girls (13–19 years old) who participated in a six-month, empowerment-based exercise intervention programme (EIP). Design: The study used a pre- and post-test randomized group design and included one pre- and one post-test (at six months) and non-physically active adolescent girls ( N = 110) were assigned to an intervention group ( n = 54) or a comparison group ( n = 56). Setting: Two upper secondary schools and five secondary schools, located in the low socio-economic areas of two communities in southern Sweden were involved in the study. Method: The Swedish version of a 10-item General Self-efficacy Scale (GSES) and the Social Barriers to Exercise Self-efficacy Questionnaire (SPBESQ) were used. In addition, BMI and results from a physical fitness test were measured. For statistical analysis, the Mann-Whitney U-test and the Wilcoxon’s matched-pairs signed-rank test were used. Results: Analysis showed a statistically significant difference in GSES scores ( p = 0.037) between the groups after the EIP was implemented. Girls in the intervention group had increased their levels of general perceived self-efficacy ( p = 0.004). Both groups increased their level of physical fitness (intervention, p = 0.06 and control, p = 0.013). BMI increased in the control group ( p = 0.031). Conclusions: The EIP had an impact on adolescent girls’ general perceived self-efficacy and can be regarded as an outcome of empowerment that indicates the development of the adolescent girls’ ability to effectively deal with a variety of stressful situations in general.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
