Sleep and Perceived Stress: An Exploratory Mediation Analysis of the Role of Self-Control and Resilience among University Students.

BACKGROUND: High levels of stress are frequent in university education, and a lack of sleep has been reported to make students more vulnerable to stress. The mechanisms through which sleep harms students have not been sufficiently clarified; therefore, this study aimed to explore the mediating role of self-control and resilience in the relationship between sleep quality and duration and perceived stress. METHODS: Of 32 first-year college students, 21 (78%) were women, with a mean age of 18.47 (±0.84). They responded to a self-administered survey that included questions on stress, resilience, and sleep quality and recorded their daily sleep duration using a wristband for six days. RESULTS: Perceived stress was significantly correlated with resilience (r = -0.63), self-control (r = -0.46), sleep duration (r = -0.35), and lower sleep quality (r = 0.57). Path analysis revealed that self-control and resilience were partially mediated by sleep quality (R2 = 0.62; p < 0.01) and completely mediated by sleep duration (R2 = 0.46; p < 0.01). In both models, self-control had a direct effect on resilience and had a good-fit index. CONCLUSION: Being resilient seems to play a mediating role in the relationship between sleep and perceived stress; this ability can be favored by self-control, which is directly influenced by sleep.

The contribution of self-concept to sleep quality in adolescents: A cross-sectional study.

Self-concept has been associated with health-related behaviors and emotional self-regulation, which can improve sleep. However, its involvement in sleep quality in a healthy adolescent population has been little studied. This study evaluated the association between self-concept and sleep quality in adolescents adjusting for sleep/wake habits. The cross-sectional study included 1,751 adolescents, 54% females, with an age of M = 16.76 ± 1.04 years. The information was collected through an electronic survey that contained the Patient Health Questionnaire, Sleep Habits Questionnaire, Pittsburgh Sleep Quality Index, and Self-Concept Scale. A significant association between self-concept, adjustment for adolescents´ characteristics and sleep/wake habits was observed (R2 = .17, F = 26.61, p < .001). That is, in addition to the adolescent habits, self-concept also contributed to the explanation of sleep/wake habits. These results reinforce the idea that the self-concept can be an essential factor that contributes to better sleep quality, despite the habits of adolescents.

Doctoring and mothering during the SARS-COV2 pandemic: Characteristics of physicians-mothers during COVID-19 and their impact on mental health / Medicina y maternidad durante la pandemia por SARS-COV2: Características de médicas madres de familia durante la Covid-19 y su impacto en la salud mental

Abstract Introduction During COVID-19, health workers faced increased stress accentuated by gender roles, such as motherhood. Objective This study analyzed the characteristics of a group of physicians-mothers, its impact on mental health, and their experiences during this pandemic. Method Mixed methods study using an online survey to investigate sociodemographic, family, emotional, and professional aspects, in addition to the personal experience of 537 doctors-mothers during the first stage of COVID-19. Results Due to the pandemic, most of the participants changed their daily activities. The hours dedicated to professional work (HM = 5.08, p< .0001), childcare (HM = 3.74, p< .0001), and food planning and preparation (HM = -6.96, p< .0001) were increased, while the hours dedicated to physical exercise (MH = 8.67, p< .0001) and personal care (MH = 9.54, p< .0001) decreased. It has been pointed out that this pandemic has generated a lack of well-defined spaces, resulting in multitasking. Fear and guilt were two common words in the speeches of the participants. Fear of getting sick and dying, or fear of infecting their families. Guilt at feeling that they did not play a good role either as doctors or as mothers. Most common psychological symptoms were insomnia, sadness or discouragement, and constant worry or tension. Discussion and conclusion The pandemic evidenced and exacerbated both the disparities faced by these female doctors in the medical field, as well as the inequity in housework and home-care. The loss of boundaries between the public and the private showed the mothers-doctor struggling to reconcile their personal and professional life with substantial repercussions for their mental health.

Resumen Introducción Durante el COVID-19, los trabajadores de la salud enfrentaron mayor estrés, acentuado por los roles de género, como la maternidad. Objetivo Analizar las características de un grupo de madres médicas, su impacto en la salud mental, y sus experiencias durante esta pandemia. Método Estudio de métodos mixtos mediante una encuesta en línea que indagó aspectos familiares, emocionales, profesionales y la experiencia personal de 537 madres médicas durante la primera etapa del COVID-19. Resultados Por la pandemia, las participantes cambiaron sus actividades diarias. Asimismo, incrementaron el número de horas dedicadas al trabajo profesional (HM = 5.08, p< .0001), el cuidado de niños (HM = 3.74, p< .0001) y la planificación y preparación de alimentos (HM = -6.96, p< .0001). Disminuyeron las horas dedicadas al ejercicio físico (MH = 8.67, p< .0001) y al cuidado personal (MH = 9.54, p< .0001). Señalaron que esta pandemia generó una falta de espacios definidos, lo que favoreció el multitasking. Miedo y culpa fueron dos palabras habituales en los discursos de las participantes. También miedo a enfermarse y morir, o miedo a contagiar a sus familias. Culpabilidad por sentir que no desempeñaron un buen papel ni como médicas ni como madres. Los síntomas psicológicos más comunes fueron insomnio, tristeza y tensión constante. Discusión y conclusión La pandemia evidenció y exacerbó las disparidades que enfrentan estas doctoras en el campo de la medicina y la inequidad en las tareas del hogar. La pérdida de los límites entre lo público y lo privado mostró a las médicas madres conciliando su vida personal y profesional, con repercusiones sustanciales para su salud mental.

Indicators of vulnerability associated with less healthy circadian rhythms in undergraduate medical interns.

To evaluate the association between circadian health parameters and psychological and biological vulnerability, a cross-sectional study was conducted with 15 undergraduate medical interns using the Brief Resilience Scale, the Mini International Neuropsychiatric Interview, and an ambulatory circadian monitoring device. Circadian Health construct was confirmed by factor analysis. Vulnerability factors (history of depression and low resilience) were associated to lower circadian health of motor activity and temperature rhythms. The findings suggest that not only being depressed but also having had depressive episodes in the past, as well as having low resilience, are associated with chronodisruption, and may increase the risk for developing new episodes of depression.
