Aim To evaluate the effectiveness on lifestyle change of an mHealth intervention to promote healthy behaviours in adolescence (TeenPower) and to analyse the predictors of the mHealth intervention effectiveness. Design This study is designed as a non‐randomized controlled trial with a two‐arm structure. Methods Adolescents of 12–16‐year old were recruited from three school districts, with access to the Internet and smartphone/tablet devices. The intervention group was invited to engage in the mHealth intervention (TeenPower) for 6 months in addition to a school‐based intervention. The control group only followed the school‐based intervention. A repeated measures factorial ANOVA was used and the main effectiveness outcome was the lifestyle change measured by the adolescent lifestyle profile. Results The outcomes of the mHealth intervention (TeenPower) show a significant effect on nutrition (ƞ2p = 0.03, p = .03), positive life perspective (ƞ2p = 0.04, p = .01), and global lifestyle (ƞ2p = 0.02, p = .05), with a dropout rate of 62.1%. The analysis of the effectiveness predictors of the mHealth intervention suggested that older adolescents tended to show a significant increase in the rates of stress management (r = .40; p < .05). Conclusions Although the considerable dropout rate, the mHealth intervention presented significant impact on multiple lifestyle domains, providing support for the effectiveness of mHealth interventions for health promotion as an add‐on to standard interdisciplinary interventions. Impact Adolescents must have the necessary and appropriate knowledge for the correct and responsible decision‐making regarding their health and lifestyle. Innovative strategies (mHealth intervention) were used to promote healthy behaviours. This study evaluates the effectiveness of an mHealth intervention (TeenPower) specifically designed for adolescents. We found a significant impact in several lifestyle domains such as health responsibility, nutrition, positive life perspective, and global lifestyle.

Aim: This paper describes the design and rationale of multicenter practice-based research that aims to develop and evaluate an innovative mobile health (mHealth) intervention programme directed to promote healthy behaviours and prevent adolescent obesity.Design: This study is designed as a non-randomized controlled trial with a threearm structure.Methods: Twelve to 16 years old participants will be recruited from schools, with access to the Internet and smartphone/tablet devices. The intervention group will be invited to engage in the TeenPower mHealth programme and divided into two subgroups: Group A (additionally engaged in a structured school-based intervention programme) and Group B (only engaged in the mHealth programme). The mHealth app includes educational resources, self-monitoring, social support, interactive training modules and motivational tools. The control group will only follow the structured school-based intervention programme. The intervention length will be 3 months, including the direct support of an interdisciplinary team (nursing, nutrition, sports, psychology, among others). This research was approved and funded in August 2017. Discussion:The positive evaluation of the intervention programme will stimulate the inclusion of technologies in the promotion of salutogenic behaviours and obesity prevention.Impact: Adolescent obesity reached epidemic proportions. It is urgent to find effective prevention strategies to induce change at the individual, family and community level. If effective, this protocol can be used by health and exercise professionals in improving community interventions tailored to teenagers.

Objective: Testing the psychometric properties of the Portuguese version of the Practice Environment Scale of the Nursing Work Index. Method: A descriptive, analytical and cross-sectional study, for the cross-cultural adaptation and validation of the psychometric properties of the scale. The study participants were 236 nurses from two hospitals in the regions of Lisbon and Vale do Tejo. Results: The 0.92 Cronbach’s alpha was obtained for overall reliability and support of a five-dimension structure. Conclusion: The excellent quality of adjustment of analysis confirms the validity of the adapted version to hospital care settings, although there was no total coincidence of items in the five dimensions

Introduction Although self-care has a therapeutic effect on heart failure (HF), patients experience a marked reduction in physical and executive function, resulting in poor quality of life (QoL). A literature review revealed limited evidence regarding the possible relationship between self-care and QoL in HF patients. Therefore, this scoping review aimed to identify scientific evidence that examines the extent of self-care, QoL, and relationship between self-care and QoL in patients with HF. Methods Full-text research published from March 23, 2010, to March 23, 2020, written in English, that had content on both self-care and QoL among adult patients with HF was included. A literature search of electronic databases and web searches was conducted for published articles. Four databases were used: MEDLINE, Scopus, Web of Science, and the Cochrane Library. Studies collected from Google and Google Scholar web searches were also included. Results Of 1,537 papers identified by the search, 12 were included. The reviewed studies included 3,127 patients. Ten articles used a cross-sectional study design, whereas the remaining articles used a longitudinal and quasi-experimental design. This review found that the extent of self-care practices among patients with HF was inadequate, a significant proportion of patients enrolled in the reviewed studies had a moderate QoL, and higher self-care practices were associated with a better QoL. Self-care behavior and QoL were affected by social support, sex, age, educational level, place of residence, illness knowledge, presence of comorbidities, and functional classification of HF. Conclusion Self-care behavior was positively correlated with QoL in patients with HF. Self-care and QoL in these patients have been reported to be affected by several factors. Further research with a rigorous study design is recommended to investigate the influence of self-care practices on QoL in patients with HF.
