Multiple sclerosis (MS) is a chronic neurological disease whose etiology has not been fully understood yet in detail. Empirical findings show how psychosocial symptoms are very important features of the clinical presentation of MS, having a deep impact on patient's quality of life, and thus psychological coping strategies may play a central role in reducing the burden of the disease and improving patient's satisfaction of life. MS progression and relapses/exacerbations are unpredictable and may depend on factors such as stressor chronicity, frequency, severity, type, and individual patient characteristics such as depression, personality, locus of control (LOC), optimism, and perceived social support. Due to its importance for health-care delivery, rehabilitation, and nursing, here, we make a systematic review on the current state-of-the-art studies concerning the relationship between LOC and MS, according to the PRISMA guidelines, and we assess the quality and the completeness of the studies using the CONSORT instrument, underpinning their limitations, and suggesting how to fill the gap in this research field.

Physical Therapy in Sport : Official... Jun 2024The aim of this review is to synthesise qualitative studies examining adolescents' experience with pain and injury arising from sports participation.
OBJECTIVE
The aim of this review is to synthesise qualitative studies examining adolescents' experience with pain and injury arising from sports participation.
METHODS
This review was registered on Open Science Framework prior to data extraction. A systematic search of PubMed, Embase, and SPORTDiscus was conducted. Studies were appraised using the CASP (critical appraisal skills programme) checklist. Data was synthesised using a meta aggregation.
STUDY SELECTION CRITERIA
Inclusion criteria included studies related to adolescents aged 14-19yrs with sports related pain/injury, employed a qualitative design, full text publications in English.
RESULTS
Sixteen studies of 216 participants were included. Studies investigated severe knee injuries, concussion, or other musculoskeletal injuries. Synthesised findings show that, regardless of injury type, adolescents experience a mix of positive (motivation to rehab and return to sport, optimism) and negative emotions (fear of re-injury, isolation, depressive responses) throughout recovery. Common coping strategies were to ignore symptoms, modify activity levels, or seek support.
CONCLUSION
Sports-related pain and injury has a multifaceted effect on the adolescent athlete. There is a pervasive fear of re-injury and social isolation, but the desire to return to sports is facilitated through motivation and support. Peer motivation effects the willingness of the adolescent to persist with rehabilitation.

Review
OBJECTIVES
We synthesized evidence regarding effective strategies for smoking cessation among employed or unemployed young adults aged 18 to 24 years.
METHODS
For this knowledge synthesis, we used (1) a systematic review of the scientific literature, (2) a Delphi panel of experts, and (3) 6 focus groups of employed and unemployed young adult smokers.
RESULTS
Of 51 related studies, only 4 included employed and unemployed young adults in their samples (as opposed to students), and none focused solely on them. Using the Delphi process, 27 experts reached consensus on priorities for research, practice, and policy, emphasizing population engagement, recruitment, and innovative interventions. Key themes from focus groups were that interventions should be relevant to young adults, individual choice should be respected, and the positive aspects of quitting should be stressed. Despite having negative views on traditional smoking cessation methods, participants expressed optimism about being able to quit and proposed creative recommendations.
CONCLUSIONS
Our findings set an agenda for targeting research, improving practice, and informing policy for smoking cessation among young adults. We also demonstrate the value of using 3 complementary approaches: literature review, expert opinion, and target population perspectives.

PURPOSE
To develop a tool that can be used to predict early discontinuation of adjuvant chemotherapy among patients with stage III colon cancer.
PATIENTS AND METHODS
Through record linkage of Alberta administrative and tumor registry databases, we identified a cohort of individuals age ≥ 18 years who were diagnosed with stage III colon cancer and who received adjuvant chemotherapy in Alberta between 2004 and 2015. Early discontinuation was defined as receipt of < 5 months of a planned 6-month course of chemotherapy. By a systematic review of the literature and a survey of medical oncologists, the following candidate variables were identified: age (years), number of comorbidities (0, 1, ≥ 2), cancer stage (IIIC IIIA-B), type of chemotherapy (fluorouracil, leucovorin, and oxaliplatin; capecitabine and oxaliplatin; or monotherapy), time from surgery to chemotherapy initiation (weeks), type of treatment facility (academic or community), and distance from home to treatment center (kilometers). Models developed using penalized logistic regression and the random forest algorithm were compared. Model performance was assessed using the C-statistic, Brier score, and a calibration plot. Internal validation was performed using the bootstrap method.
RESULTS
From an initial 3,115 patients identified, 1,378 were deemed eligible for inclusion. Of these patients, 474 patients (34.4%) failed to complete at least 5 months of chemotherapy. Although well calibrated, the penalized logistic regression model had poor discrimination (optimism-adjusted C-statistic, 0.63; 95% CI, 0.60 to 0.67). In contrast, the random forest model achieved adequate discrimination (optimism-adjusted C-statistic, 0.80; 95% CI, 0.79 to 0.82). Although the degree of calibration of the random forest was acceptable, it was slightly worse than that of the penalized logistic regression model.
CONCLUSION
Internal validation of our random forest model suggests that it may have clinical utility. Additional research regarding its external validation and clinical impact is needed.

In patients with diabetes, psychological well-being constructs (e.g., optimism, positive affect) have been associated with superior medical outcomes, including better glucose control and lower mortality rates. Well-being interventions may be well-suited to individuals with diabetes, as they are simple to deliver, broadly applicable across a range of psychological distress, and may help increase self-efficacy and motivation for diabetes self-care. This systematic review, completed using PRISMA guidelines, examined peer-reviewed studies indexed in PubMed, PsycINFO, and/or Scopus between database inception and October 2017 that investigated the effects of well-being interventions (e.g., positive psychology interventions, mindfulness-based interventions, resilience-based interventions) on psychological and physical health outcomes in individuals with Type 1 or Type 2 diabetes. The search yielded 34 articles (N = 1635 participants), with substantial variability in intervention type, measures used, and outcomes studied; the majority found the intervention to provide benefit. Overall, results indicate that a range of well-being interventions appear to have promise in improving health outcomes in this population, but the literature does not yet provide definitive data about which specific interventions are most effective. The variability in interventions and outcomes points to a need for further rigorous, controlled, and well-powered studies of specific interventions, with well-accepted, clinically relevant outcome measures.

BACKGROUND
Poor representation of pregnant and lactating women and people in clinical trials has marginalised their health concerns and denied the maternal-fetal/infant dyad benefits of innovation in therapeutic research and development. This mixed-methods systematic review synthesised factors affecting the participation of pregnant and lactating women in clinical trials, across all levels of the research ecosystem.
METHODS AND FINDINGS
We searched 8 databases from inception to 14 February 2024 to identify qualitative, quantitative, and mixed-methods studies that described factors affecting participation of pregnant and lactating women in vaccine and therapeutic clinical trials in any setting. We used thematic synthesis to analyse the qualitative literature and assessed confidence in each qualitative review finding using the GRADE-CERQual approach. We compared quantitative data against the thematic synthesis findings to assess areas of convergence or divergence. We mapped review findings to the Theoretical Domains Framework (TDF) and Capability, Opportunity, and Motivation Model of Behaviour (COM-B) to inform future development of behaviour change strategies. We included 60 papers from 27 countries. We grouped 24 review findings under 5 overarching themes: (a) interplay between perceived risks and benefits of participation in women's decision-making; (b) engagement between women and the medical and research ecosystems; (c) gender norms and decision-making autonomy; (d) factors affecting clinical trial recruitment; and (e) upstream factors in the research ecosystem. Women's willingness to participate in trials was affected by: perceived risk of the health condition weighed against an intervention's risks and benefits, therapeutic optimism, intervention acceptability, expectations of receiving higher quality care in a trial, altruistic motivations, intimate relationship dynamics, and power and trust in medicine and research. Health workers supported women's participation in trials when they perceived clinical equipoise, had hope for novel therapeutic applications, and were convinced an intervention was safe. For research staff, developing reciprocal relationships with health workers, having access to resources for trial implementation, ensuring the trial was visible to potential participants and health workers, implementing a woman-centred approach when communicating with potential participants, and emotional orientations towards the trial were factors perceived to affect recruitment. For study investigators and ethics committees, the complexities and subjectivities in risk assessments and trial design, and limited funding of such trials contributed to their reluctance in leading and approving such trials. All included studies focused on factors affecting participation of cisgender pregnant women in clinical trials; future research should consider other pregnancy-capable populations, including transgender and nonbinary people.
CONCLUSIONS
This systematic review highlights diverse factors across multiple levels and stakeholders affecting the participation of pregnant and lactating women in clinical trials. By linking identified factors to frameworks of behaviour change, we have developed theoretically informed strategies that can help optimise pregnant and lactating women's engagement, participation, and trust in such trials.

Meta-Analysis
The effect of positive psychology interventions on well-being and distress in clinical samples with psychiatric or somatic disorders: a systematic review and meta-analysis.
BACKGROUND
Although positive psychology interventions (PPIs) show beneficial effects on mental health in non-clinical populations, the current literature is inconclusive regarding its effectiveness in clinical settings. We aimed to examine the effects of PPIs on well-being (primary outcome), depression, anxiety, and stress (secondary outcomes) in clinical samples with psychiatric or somatic disorders.
METHODS
A systematic review and meta-analysis was conducted following PRISMA guidelines. PsycINFO, PubMed, and Scopus were searched for controlled studies of PPIs in clinical samples between Jan 1, 1998 and May 31, 2017. Methodological quality of each study was rated. We used Hedges' adjusted g to calculate effect sizes and pooled results using random-effect models.
RESULTS
Thirty studies were included, representing 1864 patients with clinical disorders. At post-intervention, PPIs showed significant, small effect sizes for well-being (Hedges' g = 0.24) and depression (g = 0.23) compared to control conditions when omitting outliers. Significant moderate improvements were observed for anxiety (g = 0.36). Effect sizes for stress were not significant. Follow-up effects (8-12 weeks), when available, yielded similar effect sizes. Quality of the studies was low to moderate.
CONCLUSION
These findings indicate that PPIs, wherein the focus is on eliciting positive feelings, cognitions or behaviors, not only have the potential to improve well-being, but can also reduce distress in populations with clinical disorders. Given the growing interest for PPIs in clinical settings, more high quality research is warranted as to determine the effectiveness of PPIs in clinical samples.

Review
Patients on waiting lists for kidney transplantation have higher mortality rates and have specific anxieties about their eligibility, process, and outcomes of wait-listing. We aimed to describe patient experiences and attitudes to wait-listing for kidney transplantation. Electronic databases were searched to September 2014. Thematic synthesis was used to analyze the findings. From 22 studies (n = 795 patients), we identified six themes: accepting the only option (chance to regain normality, avoiding guilt, impulsive decision-making); maintaining hope (determined optimism, appreciating a fortuitous gift, enduring for optimal outcomes, trust in clinical judgment); burden of testing (strenuous commitment, losing the battle, medical mistrust); permeating vulnerability (eligibility enigma, being threatened, angst of timing uncertainty, desperate urgency, living in limbo, spiraling doubt and disappointment, residual ambivalence); deprived of opportunity (unfairly dismissed, unexpected disqualification, self-resignation and acceptance, jealousy, suspicious of inequity); and moral guilt (awaiting someone's death, questioning deservingness). The waiting list offered hope of restored normality. However, the demands of workup, uncertainty about eligibility, and waiting times that exceeded expectations impelled patients to disillusionment, despair, and suspicion of inequity. Managing patient expectations and ensuring transparency of wait-listing and allocation decisions may allay patient disappointment and skepticism, to improve patient satisfaction and treatment outcomes.

Positive psychological constructs (eg, optimism, positive affect) have been independently associated with superior health outcomes across many medical populations. However, there has been little synthesis of the literature examining these associations among patients with hematologic malignancies receiving hematopoietic stem cell transplantation (HSCT). To address this gap we completed a systematic review, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, of studies examining relationships between positive psychological constructs and health-related outcomes (eg, psychiatric symptoms, function, health-related quality of life [HRQoL], or treatment compliance) after HSCT. Eighteen eligible studies (N = 4201; 47% women; mean age, 47.1) were identified. Optimism (n = 12 studies) was the most frequently studied positive construct and HRQoL (examined in n = 11 studies) the most common outcome. All 17 studies with quantitative analyses found a significant (P < .05) association between a positive psychological construct and a health outcome; most but not all controlled for 1 or more relevant covariates. Among patients with hematologic malignancies who receive HSCT, positive psychological constructs appear to be associated with improved HRQoL and other health outcomes. Further work is warranted to more comprehensively understand the independent effects of positive psychological constructs on a variety of health outcomes and to develop interventions to promote well-being that are adapted to the needs of this population.

BACKGROUND
Physical activity is important for all aspects of health, yet most university students are not active enough to reap these benefits. Understanding the factors that influence physical activity in the context of behaviour change theory is valuable to inform the development of effective evidence-based interventions to increase university students' physical activity. The current systematic review a) identified barriers and facilitators to university students' physical activity, b) mapped these factors to the Theoretical Domains Framework (TDF) and COM-B model, and c) ranked the relative importance of TDF domains.
METHODS
Data synthesis included qualitative, quantitative, and mixed-methods research published between 01.01.2010-15.03.2023. Four databases (MEDLINE, PsycINFO, SPORTDiscus, and Scopus) were searched to identify publications on the barriers/facilitators to university students' physical activity. Data regarding study design and key findings (i.e., participant quotes, qualitative theme descriptions, and survey results) were extracted. Framework analysis was used to code barriers/facilitators to the TDF and COM-B model. Within each TDF domain, thematic analysis was used to group similar barriers/facilitators into descriptive theme labels. TDF domains were ranked by relative importance based on frequency, elaboration, and evidence of mixed barriers/facilitators.
RESULTS
Thirty-nine studies involving 17,771 participants met the inclusion criteria. Fifty-six barriers and facilitators mapping to twelve TDF domains and the COM-B model were identified as relevant to students' physical activity. Three TDF domains, environmental context and resources (e.g., time constraints), social influences (e.g., exercising with others), and goals (e.g., prioritisation of physical activity) were judged to be of greatest relative importance (identified in > 50% of studies). TDF domains of lower relative importance were intentions, reinforcement, emotion, beliefs about consequences, knowledge, physical skills, beliefs about capabilities, cognitive and interpersonal skills, social/professional role and identity, and behavioural regulation. No barriers/facilitators relating to the TDF domains of memory, attention and decision process, or optimism were identified.
CONCLUSIONS
The current findings provide a foundation to enhance the development of theory and evidence informed interventions to support university students' engagement in physical activity. Interventions that include a focus on the TDF domains 'environmental context and resources,' 'social influences,' and 'goals,' hold particular promise for promoting active student lifestyles.
