RESUMO

AIM: To explore the International Network for Child and Family Centred Care (INCFCC) members' experiences and views on the long-term impact of COVID-19 on the nursing workforce. BACKGROUND: On the 11 March 2020, the World Health Organization declared COVID-19 a global pandemic. While some countries adopted a herd immunity approach, others imposed stricter measures to reduce the transmission of the virus. Hospitals in some countries faced an avalanche of extremely sick admissions, whereas others experienced an early surge in cases or were able to control the spread. DESIGN: Discursive paper. METHODS: A web-based survey was e-mailed to 63 INCFCC members from 28 March to 30 April 2022, as an invitation to share their experience concerning the long-term impact of COVID-19 on their role as a nurse educator, clinician or researcher. RESULTS: Sixteen members responded, and the responses were grouped under the themes stress and anxiety, safe staffing and pay, doing things differently, impact on research, impact on teaching and learning, impact on clinical practice, nursing made visible and lessons for the future. CONCLUSION: The INCFCC members provided their views and highlighted the impact on their role in nursing education, administration, research and/or practice. This discussion of international perspectives on the similarities and differences imposed by COVID-19 found that the impact was wide-ranging and prolonged. The overarching theme revealed the resilience of the participating members in the face of COVID-19. RELEVANCE TO CLINICAL PRACTICE: This study highlights the importance of all areas of nursing, be it in academia or in clinical practice, to work together to learn from the present and to plan for the future. Future work should focus on supporting organizational and personal resiliency and effective interventions to support the nursing workforce both during a disaster and in the recovery phase. Nursing workforce resilience in the face of COVID-19.

RESUMO

BACKGROUND: Globally, the COVID-19 pandemic had a huge impact on patients and healthcare systems. A decline in paediatric visits to healthcare settings was observed, which might have been due to lower incidence of injury and infectious illness, changes in healthcare services and parental concern. The aim of our study was to examine parental experiences of help-seeking for, and care of, a sick or injured child during COVID-19 lockdown periods in five European countries with different healthcare systems in place. METHODS: An online survey for parents with a child with any kind or illness of injury during COVID-19 lockdowns was circulated through social media in five European countries: Italy, Spain, Sweden, the Netherlands, and the United Kingdom. Parents living in one of these countries with self-identification of a sick or injured child during COVID-19 lockdown periods were eligible to fill in the survey. Descriptive statistics were used for the level of restrictions per country, children's characteristics, family characteristics and reported help-seeking behaviour of parents prior to the lockdown and their real experience during the lockdown. The free text data was subjected to thematic analysis. RESULTS: The survey was fully completed by 598 parents, ranging from 50 to 198 parents per country, during varying lockdown periods from March 2020 until May 2022. Parents who completed the survey were not deterred from seeking medical help for their sick or injured child during the COVID-19 pandemic. This finding was comparable in five European countries with different healthcare systems in place. Thematic analysis identified three main areas: parental experiences of access to healthcare, changes in parents' help-seeking behaviours for a sick or injured child during lockdowns, and the impact of caring for a sick or injured child during the lockdowns. Parents reported limited access to non-urgent care services and were anxious about either their child or themselves catching COVID-19. CONCLUSION: This insight into parental perspectives of help-seeking behaviour and care for a sick or injured child during COVID-19 lockdowns could inform future strategies to improve access to healthcare, and to provide parents with adequate information concerning when and where to seek help and support during pandemics.

RESUMO

BACKGROUND: Quit for new life (QFNL) is a smoking cessation initiative developed to support mothers of Aboriginal babies to quit smoking during pregnancy. The state-wide initiative provides support for pregnant women and their households including free nicotine replacement therapy (NRT) and follow up cessation advice. Services are also supported to implement systems-level changes and integrate QFNL into routine care. This study aimed to evaluate: (1) models of implementation of QFNL; (2) the uptake of QFNL; (3) the impact of QFNL on smoking behaviours; and (4) stakeholder perceptions of the initiative. METHODS: A mixed methods study was conducted comprising semi-structured interviews and analysis of routinely collected data. Interviews were conducted with 6 clients and 35 stakeholders involved in program implementation. Data were analysed using inductive content analysis. Aboriginal Maternal and Infant Health Service Data Collection (AMDC) records for the period July 2012-June 2015 were investigated to examine how many eligible women attended a service implementing QFNL and how many women took up a QFNL support. Smoking cessation rates were compared in women attending a service offering QFNL with women attending the same service prior to the implementation of QFNL to determine program impact. RESULTS: QFNL was implemented in 70 services located in 13 LHDs across New South Wales. Over 430 staff attended QFNL training, including 101 staff in Aboriginal-identified roles. In the period July 2012-June 2015 27% (n = 1549) of eligible women attended a service implementing QFNL and 21% (n = 320) of these were recorded as taking up a QFNL support. While stakeholders shared stories of success, no statistically significant impact of QFNL on smoking cessation rates was identified (N = 3502; Odds ratio (OR) = 1.28; 95% Confidence Interval (CI) = 0.96-1.70; p-value = 0.0905). QFNL was acceptable to both clients and stakeholders, increased awareness about smoking cessation, and gave staff resources to support clients. CONCLUSION: QFNL was perceived as acceptable by stakeholders and clients and provided care providers with knowledge and tangible support to offer women who presented at antenatal care as smokers, however, no statistically significant impact on rates of smoking cessation were found using the measures available.

RESUMO

BACKGROUND: Autistic children and young people (CYP) experience oral health (OH) inequalities. They are at high risk of dental disease and show significant levels of unmet need in relation to OH and access to dental care. AIM: This study aimed to gather evidence on the factors that influence OH behaviours, access to and delivery of dental care for autistic CYP. DESIGN: This was a mixed-methods narrative systematic review. DATA SOURCES: Embase, Web of Science, Dentistry & Oral Sciences Source, MEDLINE, Psychinfo, Scopus, CINAHL, SocINDEX and grey literature were the data sources for this study. REVIEW METHODS: A systematic search was conducted for qualitative, quantitative and mixed-methods research studies from countries with a High Development Index that related to OH behaviours, access to and delivery of dental care for autistic CYP. Results were analysed using narrative synthesis. RESULTS: From 59 eligible studies, 9 themes were generated: (1) affordability and accessibility; (2) autism-related factors and cognitive or motor skill differences; (3) the dental environment; (4) managing CYP's behaviour; (5) responding and adapting to the needs of the autistic CYP and their parent/carer; (6) attitude of dental health professionals (DHPs) towards autistic CYP and their parents/carers; (7) knowledge of how to care for and support CYP's OH; (8) empowerment of parents/carers and collaboration with DHPs; and (9) communication and building rapport. CONCLUSION: The adoption of healthy OH behaviours and access to dental care by autistic CYP is impacted by a range of factors including those intrinsically related to a diagnosis of autism, for example, communication and those often associated with autism, for example, sensory sensitivities. Access to better OH and dental care can be facilitated by responding to the individual needs of autistic CYP through accommodation, education and adaptation. This necessitates greater awareness and knowledge of autism amongst DHPs and the provision of appropriate services. More methodologically robust intervention studies are needed to identify effective ways to support autistic CYP in achieving good OH and access to dental care. PATIENT AND PUBLIC CONTRIBUTION: The review protocol was developed with members of the project patient and public involvement group who provided the autistic voice, contributing to the interpretation of the review findings and writing of the manuscript.

RESUMO

BACKGROUND: Infectious illness is the biggest cause of death in children due to a physical illness, particularly in children under five years. If mortality is to be reduced for this group of children, it is important to understand factors affecting their pathways to hospital. The aim of this study was to retrospectively identify organisational and environmental factors, and individual child, family, and professional factors affecting timing of admission to hospital for children under five years of age with a serious infectious illness (SII). METHODS: An explanatory modified grounded theory design was used in collaboration with parents. Two stages of data collection were conducted: Stage 1, interviews with 22 parents whose child had recently been hospitalised with a SII and 14 health professionals (HPs) involved in their pre-admission trajectories; Stage 2, focus groups with 18 parents and 16 HPs with past experience of SII in young children. Constant comparative analysis generated the explanatory theory. RESULTS: The core category was 'navigating uncertain illness trajectories for young children with serious infectious illness'. Uncertainty was prevalent throughout the parents' and HPs' stories about their experiences of navigating social rules and overburdened health services for these children. The complexity of and lack of continuity within services, family lives, social expectations and hierarchies provided the context and conditions for children's, often complex, illness trajectories. Parents reported powerlessness and perceived criticism leading to delayed help-seeking. Importantly, parents and professionals missed symptoms of serious illness. Risk averse services were found to refer more children to emergency departments. CONCLUSIONS: Parents and professionals have difficulties recognising signs of SII in young children and can feel socially constrained from seeking help. The increased burden on services has made it more difficult for professionals to spot the seriously ill child.

RESUMO

BACKGROUND: Despite efforts to reduce the burden of female genital mutilation (FGM) in Guinea, the practice remains prevalent, and health care providers are increasingly being implicated in its medicalization. This formative study was conducted to understand the factors that facilitate or impede the health sector in providing FGM prevention and care services to inform the development of health sector-based interventions. METHODS: Between April and May 2018, a mixed methods formative study was carried out using a rapid assessment methodology in three regions of Guinea-Faranah, Labe and Conakry. A structured questionnaire was completed by one hundred and fifty health care providers of different cadres and 37 semi-structured interviews were conducted with health care providers, women seeking services at public health clinics and key stakeholders, including health systems managers, heads of professional associations and schools of nursing, midwifery, and medicine as well as representatives of the Ministry of Health. Eleven focus group discussions were conducted with female and male community members. RESULTS: This study revealed health systems factors, attitudinal factors held by health care providers, and other factors, that may not only promote FGM medicalization but also impede a comprehensive health sector response. Our findings confirm that there is currently no standardized pre-service training on how to assess, document and manage complications of FGM nor are there interventions to promote the prevention of the practice within the health sector. This research also demonstrates the deeply held beliefs of health care providers and community members that perpetuate this practice, and which need to be addressed as part of a health sector approach to FGM prevention. CONCLUSION: As integral members of FGM practicing communities, health care providers understand community beliefs and norms, making them potential change agents. The health sector can support them by incorporating FGM content into their clinical training, ensuring accountability to legal and policy standards, and promoting FGM abandonment as part of a multi-sectoral approach. The findings from this formative research have informed the development of a health sector intervention that is being field tested as part of a multi-country implementation research study in Guinea, Kenya, and Somalia.


Despite the implementation of various interventions to prevent female genital mutilation (FGM), it is still widely practiced in Guinea, and health care providers are increasingly being implicated in the practice. We conducted research in three regions of Guinea, namely, Faranah, Labe and Conakry, to understand factors that might be addressed to strengthen the role of the health sector in prevention and care of women and girls who have undergone FGM. Our findings highlight the need to strengthen the capacity of health care providers to be able to identify cases of FGM and manage complications. The study also highlights the importance of engaging health care providers in efforts to prevent FGM, which will require that any trainings include an opportunity to discuss their own values and beliefs around FGM so that they are better equipped to communicate with their clients and patients in a sensitive and non-judgmental manner, whether during consultation visits or community health outreach activities. The results of this research have informed the development of a health system strengthening intervention package for the prevention and care of FGM, which is being tested in Kenya, Somalia, and Guinea.

RESUMO

Nodding Syndrome (NS) occurs within a wide spectrum of epilepsies seen in onchocerciasis endemic areas of sub-Saharan Africa. It has debilitating consequences on affected individuals and increases the socio-economic, physical and psychological burden on care-givers and their households, diminishing their standing within the community. Social science research on the disproportionate burden of the disease on females is limited. Based on ethnographic research over 3 years in northern Uganda, we explored the burden of being ill and care-giving for persons with NS from a gendered perspective. We found that NS-affected females were at greater risk of physical and psychological abuse, sexual violence, unwanted pregnancies, sexually transmitted infections and stigma, in a context of deteriorating socio-economic conditions. Primary care-givers of the NS-affected, mostly women, struggled to make ends meet and were subjected to stigma and abandonment. Targeted interventions, including legal protection for affected females, stigma reduction, and psycho-social and financial support are needed.

RESUMO

Growing numbers of women are showing interest in clitoral reconstructive surgery after 'Female Genital Mutilation'. The safety and success of reconstructive surgery, however, has not clearly been established and due to lack of evidence the World Health Organization does not recommend it. Based on anthropological research among patients who requested surgery at the Brussels specialist clinic between 2017 and 2020, this paper looks at two cases of women who actually enjoy sex and experience pleasure but request the procedure to become 'whole again' after stigmatising experiences with health-care professionals, sexual partners or gossip among African migrant communities. An ethnographic approach was used including indepth interviews and participant observation during reception appointments, gynecological consultations, sexology and psychotherapy sessions. Despite limited evidence on the safety of the surgical intervention, surgery is often perceived as the ultimate remedy for the 'missing' clitoris. Such beliefs are nourished by predominant discourses of cut women as 'sexually mutilated'. Following Butler, this article elicits how discursive practices on the physiological sex of a woman can shape her gender identity as a complete or incomplete person. We also examine what it was that changed the patients' mind about the surgery in the process of re-building their confidence through sexology therapy and psychotherapy.

RESUMO

Mosaic KRAS variants and other RASopathy genes cause oculoectodermal, encephalo-cranio-cutaneous lipomatosis, and Schimmelpenning-Feuerstein-Mims syndromes, and a spectrum of vascular malformations, overgrowth and other associated anomalies, the latter of which are only recently being characterized. We describe eight individuals in total (six unreported cases and two previously reported cases) with somatic KRAS variants and variably associated features. Given the findings of somatic overgrowth (in seven individuals) and vascular or lymphatic malformations (in eight individuals), we suggest mosaic RASopathies (mosaic KRAS variants) be considered in the differential diagnosis for individuals presenting with asymmetric overgrowth and lymphatic or vascular anomalies. We expand the association with embryonal tumors, including the third report of embryonal rhabdomyosarcoma, as well as novel findings of Wilms tumor and nephroblastomatosis in two individuals. Rare or novel findings in our series include the presence of epilepsy, polycystic kidneys, and T-cell deficiency in one individual, and multifocal lytic bone lesions in two individuals. Finally, we describe the first use of targeted therapy with a MEK inhibitor for an individual with a mosaic KRAS variant. The purposes of this report are to expand the phenotypic spectrum of mosaic KRAS-related disorders, and to propose possible mechanisms of pathogenesis, and surveillance of its associated findings.

RESUMO

AIM: Rectal neuroendocrine tumours (NETs) are the most common type of gastrointestinal NET. European Neuroendocrine Tumour Society guidelines suggest that rectal NETs measuring ≤10 mm are indolent with low risk of spread. In practice, many patients with lesions ≤1 cm do not undergo complete tumour staging. However, the size of the lesion may not be the only risk factor for nodal involvement/metastases. The aim of this study was to determine if MRI ± nuclear medicine imaging alters tumour stage in patients with rectal NETs ≤10 mm. METHODS: Patients referred to a tertiary NET centre between 2005 and 2020 who met the inclusion criteria of a rectal NET ≤10 mm, full cross-sectional imaging, primarily an MRI scan and, if abnormal findings were identified, a subsequent 68 Ga-DOTATATE positron emission tomography scan were included. All patients were followed up at our institution. RESULTS: In all, 32 patients with rectal NETs 10 mm or less were included in the study: 16 women; median age 58 years (range 33-71); 47% (n = 15) were referred from bowel cancer screening procedures. The median size of the lesions was 5 mm (range 2-10 mm). 81% (n = 26) were World Health Organization Grade 1 tumours with Ki67 <3%. Radiological staging confirmed nodal involvement in 25% (8/32); two cases had distant metastatic disease. Lymphovascular invasion was present in 3% (1/32) of patients but none demonstrated peri-neural invasion. CONCLUSION: This study demonstrates that small rectal NETs can develop nodal metastases; therefore it is important to stage these tumours accurately with MRI at baseline and, if there are concerns regarding potential lymph node metastases, to consider 68 Ga-DOTATATE positron emission tomography imaging.

RESUMO

BACKGROUND: During the COVID-19 pandemic, the first UK lockdown (March to May 2020) witnessed a dramatic reduction in children presenting to primary/emergency care, creating concern that fear of the virus was resulting in children presenting late. METHODS: An online survey was co-developed with UK parents to understand the impact of the lockdown on parents' help-seeking for, and care of, their sick/injured child(ren). The survey was advertised through social media and snowballing to parents whose children had been ill/injured during the lockdown. Analysis used descriptive statistics, SPSSv25 and thematic analysis. RESULTS: The survey was fully completed by 198 UK parents. The majority asked for help (144/198): from their family doctor (78), national helplines (48) or an Emergency Department (23). Most reported that their decision-making had not changed, although how they sought help had changed. A few parents reported that the severity and duration of illness had increased because of uncertainty about and/or difficulty accessing services. Parents did not always report seeking help for symptoms rated red or amber by the Royal College of Paediatrics and Child Health. Parents reported accessing information through the internet or using information that they already had. PARENT CONTRIBUTION: This was a collaboration with parents from survey development to dissemination, with two parents being integral members of our research team. CONCLUSIONS: Our questionnaire was completed by parents who were not deterred from seeking help for their sick or injured children. Even for these parents, the lockdown changes to services created uncertainty about, and barriers to, accessing medical help for their children.

RESUMO

The health consequences of female genital mutilation (FGM) have been described previously; however, evidence of the social consequences is more intangible. To date, few systematic reviews have addressed the impact of the practice on psycho-social well-being, and there is limited understanding of what these consequences might consist. To complement knowledge on the known health consequences, this article systematically reviewed qualitative evidence of the psycho-social impact of FGM in countries where it is originally practiced (Africa, the Middle East, and Asia) and in countries of the diaspora. Twenty-three qualitative studies describing the psycho-social impact of FGM on women's lives were selected after screening. This review provides a framework for understanding the less visible ways in which women and girls with FGM experience adverse effects that may affect their sense of identity, their self-esteem, and well-being as well as their participation in society.

RESUMO

It is the position of the International Network for Child and Family Centered Care (INCFCC) that COVID19 restrictions pose tremendous challenges for the health care team in their efforts to provide child and family centered care (CFCC). COVID-19 restrictions impact on the family's right to be presernt with their ill child and to contribute to the caring process. A limited number of articles have discussed challenges about the successful delivery of CFCC during the COVID-19 pandemic. Based on current literature, the INCFCC stresses the need for continuous facilitation implementation of child and family centred care as, it is essential for children's physical and psychological wellbeing. Furthermore we believe that the families' presence and participation holds more benefits than risks to the health of children, their families, and the health care team.

RESUMO

OBJECTIVE: This longitudinal study examined whether preschool attention deficit hyperactivity disorder (ADHD) symptoms and neuropsychological functioning predicted trajectories of children's social functioning from age 3 to 4 through 12 years. METHODS: Three- and four-year-old children (N = 208; 72.6% boys) were evaluated annually through age 12. Parent and teacher Attention Deficit/Hyperactivity Disorder Rating Scale, Fourth Edition responses during the initial evaluation were used to categorize preschoolers as "High" or "Low" risk for ADHD. Children's neuropsychological functioning was assessed using the NEPSY. Teachers' reports of children's social functioning were obtained annually from preschool through age 12 years using the Adaptability, Functional Communication, and Social Skills subscales of the Behavioral Assessment System for Children, Second Edition. Hierarchical linear modeling was used to assess the trajectories of social functioning and determine whether preschoolers' neuropsychological functioning and ADHD risk status predicted social functioning at age 12 years, and/or change in social functioning throughout childhood. All models controlled for baseline socioeconomic status. RESULTS: High Risk children had significantly lower teacher-rated Adaptability and Social Skills at age 12 years. High Risk children and those with lower Verbal neuropsychological functioning in preschool had lower teacher-rated Functional Communication at 12 years old. Lower preschool Verbal neuropsychological functioning predicted greater positive change in teacher-rated Functional Communication across childhood. CONCLUSIONS: Early identification of and intervention for children exhibiting ADHD behaviors is critical given the enduring negative impact of these behaviors on social functioning. Screening preschoolers for verbal difficulties is encouraged given their long-term impact on children's ability to clearly express thoughts and feelings and obtain and provide information.

RESUMO

The expansion of nanotechnology for drug delivery applications has raised questions regarding the safety of nanoparticles (NPs) due to their potential for interacting at molecular and cellular levels. Although polymeric NPs for drug delivery are formulated using FDA-approved polymers such as lactide- and glycolide-based polymers, their interactions with blood constituents, remain to be identified. The aim of this study was to determine the impact of size-selected Poly-lactide-co-glycolide-polyethylene glycol (PLGA-PEG) NPs on platelet activity. The NPs of 113, 321, and 585 nm sizes, were formulated and their effects at concentrations of 0-2.2 mg/mL on the activation and aggregation of platelet-rich plasma (PRP) were investigated. The results showed that NPs of 113 nm did not affect adenosine diphosphate (ADP)-induced platelet aggregation at any NP concentration studied. The NPs of 321 and 585 nm, at concentrations ≥0.25 mg/mL, reduced ADP-activated platelet aggregation. The platelet activation profile remained unchanged in the presence of investigated NPs. Confocal microscopy revealed that NPs were attached to or internalised by platelets in both resting and activated states, with no influence on platelet reactivity. The results indicate minimal risks of interference with platelet function for PLGA-PEG NPs and that these NPs can be explored as nanocarriers for targeted drug delivery to platelets.

RESUMO

Herein, we report the design and characterization of guanosine-containing self-assembling nucleopeptides that form nanosheets and nanofibers. Through spectroscopy and microscopy analysis, we propose that the peptide component of the nucleopeptide drives the assembly into ß-sheet structures with hydrogen-bonded guanosine forming additional secondary structures cooperatively within the peptide framework. Interestingly, the distinct supramolecular morphologies are driven not by metal cation responsiveness common to guanine-based materials, but by the C-terminal peptide chemistry. This work highlights the structural diversity of self-assembling nucleopeptides and will help advance the development of applications for these supramolecular guanosine-containing nucleopeptides.

RESUMO

PURPOSE OF REVIEW: Our purpose is to describe aspiration pneumonia/pneumonitis as a spectrum of infectious/noninfectious diseases affecting the lung. We summarize diagnosis, risk factors, treatment, and strategies for prevention of aspiration. RECENT FINDINGS: Aspiration is present in normal individuals, and disease manifestation depends on the chemical characteristics, frequency, and volume of inoculum. Anaerobes, though present, are no longer the predominant microbes isolated in aspiration pneumonia. Targets for preventing aspiration including improved oral hygiene and positional feeding have had mixed results. Patients diagnosed by clinicians with aspiration pneumonia experience greater morbidity and mortality than patients with community-acquired pneumonia. SUMMARY: Aspiration pneumonia and pneumonitis are part of the pneumonia continuum and share similarities in pathophysiology, microbiology, and treatment. Modern microbiology demonstrates that the lung is not sterile, and isolates in aspiration pneumonia frequently include aerobes or mixed cultures. Treatment for aspiration pneumonia should include antibiotic coverage for oral anaerobes, aerobes associated with community-acquired pneumonia, and resistant organisms depending on appropriate clinical context. Additional studies targeting prevention of aspiration and investigating the increased morbidity and mortality associated with aspiration pneumonia are warranted.

RESUMO

OBJECTIVE: Knowledge about how people make meaning in cancer, palliative, and end-of-life care is particularly lacking in Africa, yet it can provide insights into strategies for improving palliative care (PC). This study explored ways in which cancer patients, their families, and health care professionals (HCPs) construct meaning of their life-limiting illnesses and how this impact on provision and use of PC in a Nigerian hospital. METHODS: This ethnographic study utilised participant observation, informal conversations during observation, and interviews to gather data from 39 participants, comprising service users and HCPs in a Nigerian hospital. Data were analysed using Spradley's framework for ethnographic data analysis. RESULTS: Meaning-making in life-limiting illness was predominantly rooted in belief systems. Most patients and their families, including some HCPs, perceived that cancer was caused by the devil, mystical, or supernatural beings. They professed that these agents manifested in the form of either spiritual attacks or that wicked people in society used either poison or acted as witches/wizards to inflict cancer on someone. These beliefs contributed to either nonacceptance of, or late presentation for, PC by most of patients and their families, while some professionals depended on supernatural powers for divine intervention and tacitly supporting religious practices to achieve healing/cure. CONCLUSIONS: Findings revealed that cultural and religious world views about life-limiting illnesses were used in decision-making process for PC. This, therefore, provided evidence that could improve the clinicians' cultural competence when providing PC to individuals of African descent, especially Nigerians, both in Nigerian societies and in foreign countries.

RESUMO

College students from diverse ethnic and socioeconomic backgrounds are at risk for poorer academic outcomes and greater psychopathology and it is important to identify factors that are amenable to intervention and enhance college outcomes. Recent literature has entertained happiness as a potential predictor of various success outcomes and it has been suggested that parsing the concept of happiness into hedonia (seeking pleasure and relaxation) and eudaimonia (seeking meaning) may be particularly useful. This study examined the relations between hedonic and eudaimonic motives for action and student outcomes; that is, academic achievement and their negative emotional states, in an ethnically and socioeconomically diverse urban college population. Undergraduate students (N=119; mean age=21.24 [SD=3.16] years; 59.7 % female) completed self-reported measures of hedonic and eudaimonic motives for action, and depression, anxiety, and stress. Semester GPA was collected from school records. Hedonic motives for action ("Hedonia") were not associated with GPA or students' negative emotional states. Eudaimonic motives for action ("Eudaimonia"), however, were significantly positively associated with GPA, Individuals with high levels of both Hedonia and Eudaimonia (the Full Life) had higher GPAs compared to individuals with low Eudaimonia, but did not differ from students with high Eudaimonia and low Hedonia (Eudaimonic Life). Eudaimonia was also significantly negatively associated with Depression and Stress, and individuals high in Eudaimonia had the lowest levels of both of these outcomes compared to those with low Eudaimonia. Eudaimonic motives may be important for more desirable college outcomes, and interventions that promote development of this domain may hold promise.
