Forgiveness has been found one substantial element in the recovery for women survivors from intimate partner violence following the termination of the abusive relationship. To further investigate the details of forgiveness in this specific context, the present study explored the process of forgiveness using grounded theory. In-depth and semi-structured interviews were conducted with 25 Chinese women survivors of IPV. The findings suggest that forgiveness is a strength-based process including empowerment, transformation, and integration phases. In the empowerment phase, survivors obtain strength at the intrapersonal, behavioural, and interpersonal levels. In the transformation phase, survivors complete cognitive transformation for their IPV experiences and emotional transformation towards former partners. In the integration phase, survivors—now freed from the past—reflect upon and apply the changes they have undergone. Two trajectories in the process were found. One trajectory is going through stages sequentially and the other trajectory is experiencing back and forth between empowerment and transformation stages before moving into the integration stage. The study's findings broaden our knowledge of the strength-based forgiveness process that women survivors of IPV undergo during recovery. Practitioners and policymakers could develop programmes and policies that support forgiveness by holistically facilitating their recovery and empowerment like assistance in dealing with life difficulties and promoting their reconnection with social networks. To improve the transferability and validity of the findings, the forgiveness of survivors of IPV could be explored in a diverse sample (e.g., survivors with low educational background or live in the rural area).  相似文献

Introduction:Knee osteoarthritis is a common condition that affects daily functioning and decreases the quality of life. There are many ways of treatment depending on the stage of the disease. Advanced cases are qualified for arthroplasty, which is an extensive and demanding surgical procedure. Less advanced stages are treated in various ways: from rehabilitation, through oral and intra-articular pharmacotherapy, to surgical treatment (arthroscopy, osteotomy). Because surgical treatment is risky, scientists focus on less invasive therapeutic methods. The most valuable management is based on regeneration. Mesenchymal stromal cells (MSC) derived from the adipose tissue have a great regenerative and anti-inflammatory potential, therefore an attempt is being made to take advantage of them in knee osteoarthritis treatment.The study aims to compare the clinical effects of treatment of knee osteoarthritis using adipose tissue MSC obtained by an enzymatic method with the outcomes of the therapy with the mechanically fragmented adipose tissue.Methods:One hundred adults with primary knee osteoarthritis will undergo lipoaspiration under sterile conditions. The collected lipoaspirates will be further processed, depending on the randomly assigned group-enzymatically with the use of collagenase or mechanically using the Lipogems system. The preparations will be administered to the patients’ knee joints in the operating room under ultrasound control.The results of treatment will be assessed using Knee Injury and Osteoarthritis Outcome Score, measuring the flexibility of the knee joint, evaluating joint gap in X-ray and the quality of cartilage in magnetic resonance T2-mapping during 1 year after treatment.Discussion/conclusion:Identification and functional analysis of the regenerative capacity of adipose-derived MSC depending on three variables (body weight, sex, and age) will help to develop a targeted therapy for different groups of patients and will determine the effectiveness of both methods of treatment. An attempt will be made to identify groups of patients with the greatest regenerative potential of the adipose tissue, and thus indicate those with the most probable improvement of the joint condition.Trial registration:This study protocol has been approved by the Ethics Committee of Medical University of Warsaw and registered on www.clinicaltrials.gov: NCT04675359 (06 Jan 2021)  相似文献
