Purpose: Individual lifestyles have emerged as valuable health constructs. This study aims to psychometrically test the Portuguese (European) version of the Health-Promoting Lifestyle Profile-II. Methods: After an adequate linguistic and cultural adaptation of the Health-Promoting Lifestyle Profile-II scale, their psychometric properties were assessed ( N = 889) by Cronbach's alpha and confirmatory factor analysis. Findings: Results showed an adequate fit to a 52-item, six-factor structure. A global alpha of .925 was obtained. Conclusions: The Portuguese version demonstrated good validity and reliability in a wide adult sample, and can thus be applied to the Portuguese population. Implications for Nursing Practice: This instrument is useful as an evaluation tool for health-promoting lifestyles and as an instrument for testing the effectiveness of health-promoting programs.

Adolescent obesity is a major health problem. The need for effective adolescent weight management programs is of high clinical and public health relevance. This study evaluates the effectiveness of an e-therapeutic platform (Next.Step), aiming to promote weight management skills and the adoption of health-promoting lifestyles. This nonrandomized clinical trial with control group uses a sample of 94 adolescents who attended a paediatric obesity clinic. The experimental group was invited to access the platform Next.Step during 24 weeks, in addition to the standard treatment program. The control group followed the standard treatment protocol and joined a waiting list. Overall, the outcomes of the e-therapeutic program were not substantially better than those obtained with a traditional kind of intervention despite the intervention being associated with an improved health responsibility score (d = 0.51; p = 0.014). Several predictors of the Next.Step effectiveness were found. Conclusion: Although the e-therapeutic program led to a significant increase in health responsibility, inconclusive results were found regarding the program effectiveness compared to the standard multidisciplinary intervention. The lack of significant differences between groups may be due to the reduced rates of program adherence and the high dropout rate. What is Known:• Adolescent obesity has reached epidemic proportions, and standard treatment programs have been unable to achieve the desired adherence so far.• Internet-based programs have already shown positive results in the adult obese population, but information is scarce regarding adolescents. What is New:• This study assesses the effectiveness of a structured case management program including communication technologies on both the behavioural change and the health of obese adolescents.• The e-therapeutic program led to an increase in health responsibility.

ObjectiveReliable and valid instruments are essential for understanding health‐promoting behaviors in adolescents. This study analyzed the psychometric properties of the Portuguese version of the Adolescent Lifestyle Profile (ALP).MethodsA linguistic and cultural translation of the ALP was conducted with 236 adolescents from two different settings: a community (n=141) and a clinical setting (n=95). Internal consistency reliability and confirmatory factor analysis were performed.ResultsResults showed an adequate fit to data, yielding a 36‐item, seven‐factor structure (CMIN/DF=1.667, CFI=0.807, GFI=0.822, RMR=0.051, RMSEA=0.053, PNFI=0.575, PCFI=0.731). The ALP presented a high internal consistency (α=0.866), with the subscales presenting moderate reliability values (from 0.492 to 0.747). The highest values were in Interpersonal Relations (3.059±0.523) and Positive Life Perspective (2.985±0.588). Some gender differences were found. Findings showed that adolescents from the clinic reported an overall healthier lifestyle than those from the community setting (2.598±0.379 vs. 2.504±0.346; t=1.976, p=0.049).ConclusionThe ALP Portuguese version is a psychometrically reliable, valid, and useful measurement instrument for assessing health‐promoting lifestyles in adolescence. The ALP is cross‐culturally validated and can decisively contribute to a better understanding of adolescent health promotion needs. Additional research is needed to evaluate the instrument's predictive validity, as well as its clinical relevance for practice and researchResumoObjetivoOs instrumentos confiáveis e válidos são fundamentais para entender os estilos de vida de promoção da saúde de adolescentes. Este estudo analisa as propriedades psicométricas da versão em português do Perfil do Estilo de Vida Adolescente (ALP).MétodosFoi feita uma tradução linguística e cultural do ALP com 236 adolescentes de duas configurações diferentes: uma de comunidade (n=141) e uma clínica (n=95). Foram feitas uma análise da confiabilidade da coerência interna e uma análise fatorial confirmatória.ResultadosOs resultados mostraram‐se adequados aos dados e geraram uma estrutura de sete fatores com 36 itens (CMIN/DF=1,667, IAC=0,807, GFI=0,822, RMR=0,051, RMSEA=0,053, PNFI=0,575, PCFI=0,731). O ALP apresentou grande coerência interna (α=0,866). As subescalas apresentaram valores de confiabilidade moderados (de 0,492 a 0,747). Os maiores valores foram de Relações Interpessoais (3,059±0,523) e Perspectiva de Vida Positiva (2,985±0,588). Foram encontradas algumas diferenças entre os sexos. Os achados mostraram que os adolescentes da clínica relataram um estilo de vida mais saudável em geral do que os da configuração da comunidade (2,598±0,379 em comparação com 2,504±0,346; t=1,976, p=0,049).ConclusãoA versão em português do ALP é um instrumento de mensuração psicometricamente confiável, válido e útil para avaliar os estilos de vida de promoção da saúde na adolescência. O ALP é validado em diferentes culturas e pode contribuir de forma decisiva para um melhor entendimento das necessidades de promoção da saúde na adolescência. É necessária uma pesquisa adicional para avaliar a validade preditiva do instrumento, bem como sua relevância clínica para a prática e pesquisa

The current study evaluates the usability perception of an e-therapeutic platform (supported by electronic processes and communication), aiming to promote the behavior change and to improve the adolescent health status through increased and interactive contact between the adolescent and the clinical staff. This was a correlational study with a sample of 48 adolescents (12-18 years) who attended a Pediatric Obesity Clinic between January and August of 2012. Participants were invited to access, during 24 weeks, the e-therapeutic multidisciplinary platform (Next.Step) in addition to the standard treatment program. A usability questionnaire was administered and the platform performance and utilization indicators were analyzed. The users' perception of satisfaction, efficiency, and effectiveness regarding the Next.Step platform was clearly positive. However, only 54.17% of the enrolled adolescents accessed the platform, with a mean task-completion rate of 14.55% (SD=18.853). The higher the number of the platform consulted resources, the greater the tendency to enjoy the platform, to consider it exciting and quick, to consider that the time spent in it was useful, to consider the access to information easy, and to login easier. Post-intervention assessment revealed a significant reduction in anthropometric and behavioral variables, including body mass index z-score, waist circumference percentile, hip circumference, and weekly screen time. These results highlight the importance of information and communication technologies in the health information access and the healthcare provision. Despite the limited adherence rate, platform users expressed a positive overall perception of its usability and presented a positive anthropometric and behavioral progress.
