A large body of evidence supports the notion that chronic stress and strain may impact healing from physical trauma. However, no evidence exists to substantiate whether chronic stress impacts recovery from exercise-induced muscle damage. In this study, a group of 31 undergraduate weight-training students completed the Perceived Stress Scale (PSS), Undergraduate Stress Survey (USQ, a measure of life event stress) a series of fitness tests and then returned 5 to 10 days later for an exhaustive resistance exercise stimulus (E-RES) workout. This workout was performed on a leg press to the cadence of a metronome to ensure a strong eccentric component of exercise. Participants were monitored for 1 hour after this workout and every day for 4 days afterwards. Hierarchical Linear Modeling (HLM) multi-level growth curve analyses demonstrated that stress measures were related to recovery from maximal resistance exercise for both functional muscular (maximal isometric force, jump height, and cycling power) and psychological (perceived energy, perceived fatigue, and soreness) outcomes. Stress was not related to outcomes immediately post-workout (except maximal cycling power) after controlling for pre-workout values. Thus, the effect of stress on recovery is not likely due to magnitude of disruption from maximal exercise. After controlling for significant covariates, including fitness and percent disruption from baseline, individuals scoring a 10 on the PSS at their first visit reached baseline 288% (2.88 times) faster than individuals who scored a 19 at this same time point. There were significant moderating effects of stress on affective responses during exercise. Feeling (pleasure/displeasure), activation (arousal), muscular pain and RPE (exertion) trajectories were moderated by stress. Exploratory analyses found that stress moderated physical recovery, but not psychological recovery in the first hour after the E-RES workout. Also, stress was related to the increase in IL-1[beta], a pro-inflammatory cytokine, in the 48 hour period after exercise for a sub-set of participants. These findings likely have important theoretical and clinical implications for those undergoing vigorous physical activity. Those experiencing chronic loads of stress and mental strain should include more rest time to ensure proper recovery. / text

Det arbetas mer och mer gränslöst, där gränserna mellan privatliv och arbetsliv suddas ut parallellt medsjukskrivningarna för reaktioner på stress ökar. Hur kan personlighetsdrag predicera upplevd stress ochvälmående? Detta kan tillämpas vid arbete med friskfaktorer som bidrar till välmående på arbetsplatsen.Perceived Stress Scale är den mest använda självskattningen inom stress, välmåendeformuläret visarutmärkt reliabilitet och god validitet. Inom personlighetsteorier representerar femfaktormodellen(neuroticism, extraversion, öppenhet, vänlighet och samvetsgrannhet) personlighetsdragen. Enligttidigare forskning utgör neuroticism en särskild sårbarhet för stress. Tre hypoteser prövades där syftetmed studien var att predicera hur personligheten påverkar välmåendet samt benägenheten att upplevastress. Deltagarna som svarade på enkäten var 1545 till antalet i åldrarna 18-71 år utspridda i Sverige.Korrelationsanalyser och multipla regressionsanalysen genomfördes. Hypotesen får stöd i studien,personlighetsdrag kan predicera upplevd stress och välmående. En tydlig korrelation fanns mellanvariablerna stress och samtliga personlighetsdimensioner. / The working life gets more and more boundaryless, the line between private and working life is blurred out and at the same time the sick leave for stress increases. Can personality traits predict perceived stress and well-being? It could be applied to the workplace and contribute to a more healthy life style. Perceived stress scale is the most used questionnaire for stress, the well-being form shows excellent reliability and good validity. Within personality theories, the big five Inventory model (neuroticism, extraversion, openness, kindness and conscientiousness) represents the traits of personality. According to previous research, neuroticism been predicted as a stress factor. Four hypotheses were tested and the purpose of the study was to predict how different personality traits can affect well-being and the tendency to experience stress. The study involved 1545 participants between 18-71 years old in Sweden. Correlation analyzes and multiple regression analyzes were performed. The question is supported in the study, personality traits can predict perceived stress and well-being. There was a clear correlation between the variables stress and all personality dimensions.

Bakgrund: Hög arbetsbelastning i kombination med brist på kompetent personal kan leda till hög grad av stress och är ett problem som idag hotar den svenska sjukvården. Arbetsrelaterad stress kan leda till en etisk stress hos sjuksköterskan, som riskerar att inte få tillräckligt med tid för sina patienter. Detta kan i sig riskera patientsäkerheten. Tidigare forskning visar på att fysisk aktivitet har en god påverkan på den mentala hälsan och kan fungera preventivt mot stress.  Syfte: Syftet var att undersöka om det finns skillnader i arbetsrelaterad stress bland sjuksköterskor som utövar fysisk aktivitet i högre respektive lägre grad. Metod: En icke-experimentell tvärsnittsstudie med kvantitativ ansats har genomförts. Enkäten som utgjordes av Perceived Stress Scale-10 och Saltin-Grimby Physical Activity Scale distribuerades som en webbenkät på två sjukhus i södra Sverige. Totalt svarade 19 sjuksköterskor på enkäten vilket resulterade i en svarsfrekvens på 10,8 procent.  Resultat: Majoriteten av deltagarna utövade någon form av fysisk aktivitet på fritiden och baserat på svaren gick det att se en generellt låg grad av arbetsrelaterad stress. Gruppen som angav lägre fysisk aktivitet upplever högre grad av arbetsrelaterad stress än den gruppen som angav högre fysisk aktivitet. Slutsats: Det finns skillnader i arbetsrelaterad stress mellan grupperna som utövar fysisk aktivitet i lägre respektive högre grad. På grund av låg svarsfrekvens och därmed litet datamaterial är det svårt att dra generella slutsatser kring resultatet. Trots detta antyder ändå resultatet att det finns en skillnad i arbetsrelaterad stress mellan sjuksköterskor som utövar fysisk aktivitet i lägre respektive högre grad.

The psychosocial and cultural predictors of cigarette smoking were examined among a sample of 175 African-American adults. Participants completed a self-report inventory containing the Beck Depression Inventory, the Perceived Stress Scale, the Speilberger State-Trait Anxiety, the African-American Acculturation Scale, and questions regarding their smoking, demographics, and risk-taking tendencies.

However, because it is a latent variable, specific instruments are needed to measure it. The Perceived Stress Scale (PSS) is an instrument that has been used to assess the perception of stress in the last month. Despite numerous validations in several countries, their psychometric properties have not been consensual. The main objective of this work was to investigate the internal structure of the PSS-10 and PSS-14 versions, through exploratory factorial (AFE) and network analysis. Thus, two studies were carried out: in Study I, PSS-10 and PSS-14 were analyzed through AFE and, in study II, the scales were analyzed through network analysis. We used: a) the PSS-10 with a sample composed of 686 participants, being 175 (27.3%) men and 466 (72.7%) women (n = 641), with a mean age of 33.9 SD = 11.3) years, ranging from 18 to 73 (n = 632); and (b) the PSS-14 was answered by 690 participants, of which 304 (44.1%) were men and 386 (55.9.7%) were women, with a mean age of 34.72 (SD = 12, 56), with a range of 18 to 65. In both analyzes, the psychometric properties of PSS-10 and PSS-14 were shown to be reliable and confirmed the two-dimensional structure of distress and coping. Also, the network analysis allowed to explore the PSS in the Brazilian context, allowing new association patterns to emerge from the analyzed samples. And, even AFE being a widely used technique in the construction and evaluation of psychometric tests, network analysis has shown to be a promising and much more comprehensive tool at the level of the symptom, accommodating the numerous processes of psychological constructions. In this study, the network analysis showed how the perception of control influences the outcome of stress. Thus, in addition to providing evidence of validity of the PSS-10 and PSS-14, this study demonstrated how much the network analysis has to contribute in the psychology and health area. / O estresse ? um dos construtos enfatizados quando se avalia o processo sa?de- doen?a. No entanto, por ser uma vari?vel latente, instrumentos espec?ficos s?o necess?rios para mensur?-lo. A Escala de Estresse Percebido (Perceived Stress Scale - PSS) ? um instrumento que tem sido utilizado para avaliar a percep??o do estresse no ?ltimo m?s. Apesar de in?meras valida??es em diversos pa?ses, suas propriedades psicom?tricas n?o t?m sido consensuais. O objetivo principal deste trabalho foi investigar a estrutura interna das vers?es PSS-10 e PSS-14, por meio de an?lise fatorial explorat?ria (AFE) e de rede. Assim, dois estudos foram realizados: no Estudo I, a PSS-10 e a PSS-14 foram analisadas atrav?s da AFE e, no estudo II, analisaram-se as escalas por meio da an?lise de rede. Foram utilizadas: a) a PSS-10 com uma amostra composta por 686 participantes, sendo 175 (27,3%) homens e 466 (72,7%) mulheres (n = 641), com m?dia de idade de 33,9 (SD = 11,3) anos, com amplitude de 18 a 73 (n = 632); e b) a PSS-14 que foi respondida por 690 participantes, dos quais 304 (44,1%) s?o homens e 386 (55,9,7%), mulheres, com m?dia de idade de 34,72 (SD = 12,56) anos, com amplitude de 18 a 65. Nas duas an?lises, as propriedades psicom?tricas da PSS-10 e PSS-14 demonstraram-se confi?veis e confirmaram a estrutura bidimensional de distress e coping. Ainda, a an?lise de rede permitiu explorar a PSS no contexto brasileiro, permitindo que novos padr?es de associa??o emergissem das amostras analisadas. E, mesmo a AFE sendo t?cnica muito utilizada na constru??o e avalia??o de testes psicom?tricos, a an?lise de rede demonstra ser uma ferramenta promissora e muito mais abrangente no n?vel do sintoma, acomodando os numerosos processos das constru??es psicol?gicas. Neste estudo, a an?lise de rede evidenciou o quanto a percep??o de controle influencia no desfecho do estresse. Assim, al?m de fornecer evid?ncias de validade da PSS-10 e PSS-14, este estudo demonstrou o quanto ? an?lise de rede tem a contribuir no ?mbito da psicologia e na ?rea da sa?de.

Objectives Different studies have reported the association between perceived stress and unhealthy diet choices. We aimed to determine whether there is a relationship between perceived stress and fat intake among undergraduate medical students. Methods/Principal findings A cross-sectional study was performed including first-year medical students. The outcome of interest was the self-report of fat intake assessed using the Block Screening Questionnaire for Fat Intake (high vs. low intake), whereas the exposure was perceived stress (low/ normal vs. high levels). The prevalence of high fat intake was estimated and the association of interest was determined using prevalence ratios (PR) and 95% confidence intervals (95% CI). Models were created utilizing Poisson regression with robust standard errors. Data from 523 students were analyzed, 52.0% female, mean age 19.0 (SD 1.7) years. The prevalence of high fat intake was 42.4% (CI: 38.2%–46.7%). In multivariate model and compared with those with lowest levels of stress, those in the middle (PR = 1.59; 95%CI: 1.20–2.12) and highest (PR = 1.92; 95%CI: 1.46–2.53) categories of perceived stress had greater prevalence of fat intake. Gender was an effect modifier of this association (p = 0.008). Conclusions Greater levels of perceived stress were associated with higher fat intake, and this association was stronger among males. More than 40% of students reported having high fat consumption. Our results suggest the need to implement strategies that promote decreased fat intake.
