Abstract
Objective: to analyze the factorial structure of the Perception Scale of Nursing Activities that Contribute to the Quality of Care. Method: a methodological study with 3,451 nurses from 36 Portuguese hospitals. In addition to carrying out confirmatory factorial analysis, Cronbach’s alpha and composite reliability were used to assess the reliability of the obtained factorial model. Results: the factorial weights of the solution found were mostly high; the values of the model’s adjustment indexes were reasonable; Cronbach’s alpha was elevated for the entire scale and five dimensions, being acceptable in only one dimension. The composite reliability was also high in five dimensions, except for one, considered acceptable. All activities showed high individual reliability. Conclusion: Compared to the original scale, the identified factorial model contemplates six dimensions and not seven, producing a reliable and valid scale, which can be applied in the hospital context.

Abstract
Aim To analyse the impact of COVID-19 on professional nursing practice environments and patient safety culture. Background The relationship between work environments and patient safety has been internationally recognized. In 2020, the pandemic imposed enormous challenges, yet the impact on these variables remains unknown. Method This is a quantitative observational study, conducted in a Portuguese hospital, with 403 registered nurses. A self-completion questionnaire was used. Results The impact on the Structure and Outcome components of nursing professional practice environments was positive. Although the Process component remained favourable to quality of care, a negative trend was confirmed in almost all dimensions. The results regarding safety culture showed weaknesses; 'teamwork within units' was the only dimension that maintained a positive culture. Conclusion Positive responses regarding patient safety were significantly associated with the quality of the nursing professional practice environment. The need to invest in all dimensions of safety culture emerges to promote positive professional environments. Implications for nursing management Improving professional nursing practice environments can be achieved through managers' investment in the participation and involvement of nurses in the policies and functioning of institutions, as well as promoting an open, fair and participatory safety culture that encourages reporting events and provides adequate support for professionals.

Abstract
PurposeExergames, which combine digital games and physical exercise, have become increasingly popular for rehabilitation in the health domain. This study aimed to assess the effectiveness of exergame rehabilitation on the quality of life of cancer patients undergoing abdominal surgery.MethodsThis randomized controlled trial evaluated the effectiveness of exergame rehabilitation on the quality of life of cancer patients who had undergone abdominal surgery. Seventy postoperative patients were included, and data collection took place between January 2023 and May 2023. The patients were randomly assigned to either an exergame rehabilitation program (n = 35) or a traditional rehabilitation program (n = 35). The assessed outcome was the quality of life, and data collection occurred at three different time points: upon admission, 48 h postoperatively, and on the 7th day after surgery.ResultsQuality of life was evaluated using the WHOQOL-BREF Scale. At the third assessment, a statistically significant difference was observed between the two groups (p = 0.016), indicating that the intervention group had a higher quality of life than the control group.ConclusionsThe study showed a positive effect of exergames on the population under investigation. By the 7th day after surgery, the intervention group demonstrated an improvement in their quality of life compared to the control group.Clinical trial registrationCenter of Open Science OSF https://osf.io/286zb/, registered in July, 2023.

Abstract
BackgroundDialysis recovery time (DRT) refers to the period during which fatigue and weakness subside following hemodialysis treatment, allowing patients to resume their daily routines. This study aimed to identify the factors influencing DRT in hemodialysis patients in Turkey and Portugal, where the prevalence of chronic kidney disease is notably high.MethodsA cross-sectional observational study was conducted in a private dialysis center in Turkey and three dialysis centers in Portugal. The study included hemodialysis patients aged 18 years or older who had been undergoing four-hour hemodialysis sessions three times a week for at least six months. Participants had no communication barriers and voluntarily agreed to take part in the study. Data were collected using a semi-structured questionnaire to gather descriptive characteristics and the Hospital Anxiety and Depression Scale. Logistic regression analysis was employed to identify independent variables influencing DRT.ResultsA total of 294 patients participated in the study, including 187 from Turkey and 107 from Portugal. In Turkey, increased interdialytic weight gain (P = 0.043) was associated with prolonged recovery time, while the use of high-flux dialyzers (P = 0.026) was linked to shorter recovery times. In Portugal, older age (P = 0.020) was found to extend recovery time.ConclusionRecovery time after dialysis is influenced by varying factors across different countries. Further research with larger sample sizes is needed to deepen understanding of these factors and their implications.Clinical trial numberNCT04667741.

Abstract
Contemporary transformations in the world of work, together with the growing emotional and physical demands in nursing, have led to the emergence of new labor phenomena such as quiet quitting, which reflects changes in professional engagement and in the management of nurses’ well-being. Objective: To translate, culturally adapt, and validate the Quiet Quitting Scale for European Portuguese, evaluating its psychometric properties among the nursing population. Methods: A cross-sectional validation study was conducted following COSMIN guidelines. The process included forward and back translation, expert panel review, and pretesting with 30 nurses. The psychometric evaluation was carried out with 347 nurses from Northern Portugal. Data were analyzed using descriptive and inferential statistics, internal consistency measures (Cronbach’s a and McDonald’s ?), and confirmatory factor analysis (CFA) with maximum likelihood estimation to assess construct validity. Results: The Portuguese version (QQS-PT) maintained the original three-factor structure (Detachment/Disinterest, Lack of Initiative, and Lack of Motivation). The model showed satisfactory fit indices (CFI = 0.936; GFI = 0.901; AGFI = 0.814; TLI = 0.905; RMSEA = 0.133). The overall internal consistency was excellent (a = 0.918; ? = 0.922), with subscale a ranging from 0.788 to 0.924. Composite reliability (CR) ranged from 0.815 to 0.924, and average variance extracted (AVE) from 0.606 to 0.859, confirming convergent and discriminant validity. Conclusions: The QQS-PT demonstrated a stable factorial structure, strong reliability, and solid validity evidence. It is a brief and psychometrically sound instrument for assessing quiet quitting among nurses, providing valuable insights for research and management of professional engagement and well-being in healthcare contexts.
