AbstractPurpose: While a wide range of psychosocial oncological (PO) interventions has been developed, a systematic overview of interventions to inform patients, care providers, as well as researchers, policy makers and health insurers, is lacking. The aims of this paper were (1) to describe the attainment of this overview, which may be used in other jurisdictions and for other health conditions and (2) to reflect on what determines developments in this field.Methods: Dutch researchers and care providers were invited to describe PO-interventions they apply in research or clinical practice. Selection criteria for what constituted a PO-intervention were determined. The input was organized in 12 predefined categories (e.g. physical functioning, genetics).Findings: Sixty-six PO-interventions were included in the overview. Two major categories were psychosocial functioning (24%) and physical functioning and recovery (24%). Interventions are mostly directed at adults (65%) and not aimed at a specific type of cancer (61%). Nearly 25% of the interventions lacked scientific underpinning.Conclusions: This paper provides an overview of Dutch PO-interventions and input on what drives their development. The categorizing method can be used in other jurisdictions and for other health care conditions. A next step would be to investigate the effectiveness and evidence of PO-interventions.Implications for Psychosocial Providers and Policy: The open access overview of interventions provides referral information for care providers. By identifying possible gaps and overlap, the overview looks at possible drivers behind developments in this field which will be of interest to policy makers. 相似文献

AbstractPurpose: We examined underlying psychosocial processes of a behavioral treatment for urinary incontinence (UI) of prostate cancer survivors.Design: Secondary analysis of data collected from a clinical trial.Sample: Two hundred forty-four prostate cancer survivors who participated in a clinical trial of behavioral intervention to UI as intervention or control subjects.Methods: The participants had a 3-month behavioral intervention or usual care and were followed up for an additional 3?months. They were assessed at baseline, 3, and 6?months. Latent growth curve models were performed to examine trajectories of each study variable and relationships among the variables.Findings: Increasing self-efficacy and social support were significantly and independently associated with more reduction of urinary leakage frequency over time.Implications for psychosocial oncology: Providing problem-solving skills and social support, including peer support, are essential for empowering patients to reduce UI. 相似文献

BackgroundAttachment and intimacy play an important role in shaping sexual and relational experiences. Yet, their interrelation has rarely been investigated in the context of sexual problems and never been tested in Saudi Arabian women.AimThe present study examined the interrelations of attachment orientation and sexual function, distress, satisfaction, and relational satisfaction in a sample of Saudi Arabian women and explored whether this link can be explained by 2 important aspects of (sexual) intimacy, namely perceived partner responsiveness (PPR) and sexual assertiveness.MethodThis is a cross-sectional, observational study in a sample of 50 heterosexual women with sexual problems and 50 control women without problems, who completed an Arabic version of questionnaires on attachment orientation, sexual assertiveness, PPR, relationship satisfaction, sexual satisfaction, sexual distress, and sexual function.ResultsWe found that both attachment anxiety and sexual refusal showed a significant association with the level of sexual function, sexual distress, and sexual satisfaction (P < .01) in the clinical group. No mediating effects of sexual refusal were found. In the control group, sexual function, sexual distress, and sexual satisfaction were predicted by attachment avoidance (P < .01). Level of sexual function was also predicted by sexual initiation (P < .05). PPR fully mediated the association between attachment anxiety and relational satisfaction in the clinical group (P < .01), while in the control group the link between attachment avoidance and relational satisfaction was only partially mediated by PPR (P < .01).Strengths & LimitationsThis study offers unique information on relational and sexual functioning in a culture in which sexual expression and intimate behavior are restricted, particularly in women.Clinical ImplicationsPerceiving the partner as being more responsive is an important target of intervention to increase satisfaction with the relationship.ConclusionsOur results suggest that attachment anxiety and low sexual assertiveness, as indicated by lower tendencies to refuse sex when not desired, play a significant role in predicting negative sexual experiences in women who cope with sexual difficulties.Attaky A, Kok G, Dewitte M.

Perinatal care providers are likely to encounter adverse events such as intrapartum emergencies, traumatic births, or maternal or fetal deaths. As a result of being directly or indirectly involved in an adverse event, health care providers can be considered second victims. The experience of the second victim phenomenon can lead to significant physical, psychological, and psychosocial sequelae that can negatively impact the provider's personal and professional life for either a short or long duration of time. When health care providers experience an adverse event, they may manifest symptoms of guilt, shame, blame, flashbacks, nightmares, insomnia, isolation, helplessness, and hopelessness, thereby becoming the second victim. Following an adverse event, health care providers who experience second victim phenomenon experience stages of recovery that influence subsequent professional and personal well‐being. Persons who experience the second victim phenomenon can incorporate self‐care behaviors to assist with recovery. Health care organizations have a responsibility to implement efficacious support programs that promote the provider's recovery and a return to safe and full function in the workplace. 相似文献

《Radiography》2020,26(4):e284-e289
IntroductionRadiographers employed in remote locations such as Far North Queensland (FNQ) can face unique sets of challenges as they often perform radiographic and sonographic diagnostic imaging without onsite radiologists' services. Additionally, the majority of patients presenting to these sites are Indigenous for whom English may be their third language. This non-participant observational study observed two FNQ radiographers' interactions with patients and interprofessional staff, and the radiographers' ability to fit into the Indigenous community during routine radiographic and sonographic examinations which to date have received little attention.MethodsNon-participant observations and semi-structured interviews with radiographers were held at two FNQ hospitals. Consecutive radiographer–patient interactions were observed and recorded on checklists. Interviews were audio recorded and transcribed for thematic analysis.ResultsAcross both remote sites, 24 patients were observed as they underwent diagnostic imaging examinations, with the majority being Aboriginal or Torres Strait Islanders (n = 17/24 (70.8%). In total, eleven general radiography and sixteen ultrasound examinations were observed. Semi-structured interviews highlighted complex issues such as the need for radiographer communication in local dialect, ongoing interprofessional collaborations, overcoming the lack of radiologists' onsite support by providing radiographic reports directly to referring doctors and midwives, and isolation with regard to professional development opportunities.ConclusionsRadiographers working in remote hospitals need to be culturally competent, navigate local indigenous languages and possess excellent interprofessional skills as well as thorough knowledge of imaging pathology to convey findings to referring doctors and allied health professionals. These findings have implications for the entry to practice curriculum.Implications for practiceThis study provides evidence that culturally competent radiographers are capable of undertaking reporting roles to facilitate patient management in the absence of timely radiologists' reports at remote sites. 相似文献

ObjectiveGrowing evidence demonstrates that perceived discrimination and racism are significant contributing factors to psychological distress, low-grade chronic inflammation, and cardiovascular health disparities among minorities, particularly among Black women. Despite this evidence, there are no evidence-based complementary therapy interventions available to ameliorate chronic stress associated with racism and discrimination. The purpose of this study was to examine the feasibility and effectiveness of a novel, 8-week, group-based stress reduction program, Resilience, Stress and Ethnicity (RiSE), designed to help Black women at risk for cardiovascular disease (CVD) develop effective coping skills for dealing with chronic stress uniquely associated with being a minority.MethodsWe conducted two semi-structured focus groups with Black women (N = 22) following their participation in the 8-week RiSE program. We analyzed the data using constant comparative qualitative methods.ResultsAttrition rate was low (13%) with all participants attending at least 6 of the 8 classes. Participants reported high levels of satisfaction with the program and the majority (81%) reported practicing the skills that they learned in real-life stressful situations. In describing the participants’ response to the program, four key categories emerged from the data: (1) Increasing awareness of stressors associated with perceived discrimination and racism; (2) Coping with race-based stressors; (3) Coping with other sources of stress; and (4) Increasing sense of empowerment and emotion regulation.ConclusionsFindings suggest that RiSE is feasible and effective in helping Black women at risk for CVD cope with chronic stress associated with being a minority. Given evidence that perceived discrimination and racism are underlying factors in many inflammatory-based chronic diseases, this research may have broader implications for reducing health disparities across a wide-spectrum of chronic illnesses in which women minorities are disproportionately affected. 相似文献
