Individual, co-active and collective coping and organizational stress: A longitudinal study

2019

This study aims to identify the association between changes in three types of problem-focused coping (individual, organizational co-active and collective) and the change in the appraisal of different facets of employees' stress and the organizational stress climate. These relationships are tested by means of Bayesian Multilevel Structural Equation Modeling and a two-wave panel design. The sample is composed of 525 teachers in 100 schools. Stress experiences and coping behaviors are assessed during the first and third terms of the academic year. The results show that an increase in the use of individual problem-focused coping has little to no effect on the decrease in individual stress appra…

Coping with everyday stress and links to medical and psychosocial adaptation in diabetic adolescents.

2003

Abstract Purpose To study coping with everyday stressors in a longitudinal sample of 98 adolescents with insulin-dependent mellitus (type 1) diabetes. Methods The adolescents with type 1 diabetes were classified into three homogeneous groups of metabolic control by latent class analysis, based on annual tests of hemoglobin A1 values. Questionnaires assessing frequent minor stressors as well as ways of coping with these stressors were given annually over the course of 4 years. Latent class analysis revealed three distinctive groups of metabolic control over time. Adolescents who exhibited continuously poor, satisfactory, and good metabolic control. Eighty percent of the adolescents stayed in…

Study Protocol—Coping With the Pandemics: What Works Best to Reduce Anxiety and Depressive Symptoms

2021

Background: The coronavirus disease 2019 (COVID-19) pandemic and lockdown might increase anxiety and depressive symptoms in most individuals. Health bodies recommend several coping behaviors to protect against such symptoms, but evidence on the relationship between these behaviors and symptoms mostly comes from cross-sectional studies in convenience samples. We will conduct a prospective longitudinal study of the associations between coping behaviors and subsequent anxiety and depressive symptoms during the COVID-19 pandemic in a representative sample of the Spanish general adult population.Methods: We will recruit 1,000 adult participants from all autonomous communities of Spain and with s…

PENDEKATAN ANALISIS REGRESI INDIVIDUAL UNTUK DATA LONGITUDINAL

2008

<p><em>Classical Regression analysis are usually used in analysing longitude data or repeated measurement data (where response from each individual were measured in a period of time). Assumption of the analysis is no correlation among a couple measurement at same object. Whereas the repeated measurement data in same object research usually  have correlation. Neglecting of correlation in regresion analysis will result in an uncertain conclusion.Regression individually analysis for longitudinal data attention the influence of individual effect and its interaction with time. So that with the reason, withdrawal of conclusion will be more be trusted its truth.The research objective i…

Multicomponent Exercise Training Combined with Nutritional Counselling Improves Physical Function, Biochemical and Anthropometric Profiles in Obese C…

2020

Aerobics or strength exercise plus diet interventions have been shown to counteract childhood obesity. However, little is known with regard to periodized multicomponent exercise interventions combined with nutritional counselling, which might be less demanding but more enjoyable and respectful of children and adolescents&rsquo

Nurse‐led counseling for coronary artery disease patients: A 1‐year follow‐up study

2021

Nurse-led counseling and systematic follow-up has been shown to reduce cardiovascular risk factor levels. The study aim was to investigate if cardiovascular risk factor levels could be reduced in patients with coronary artery disease with a nurse-led intervention and to report patients’ evaluations of nurse-led counseling. The study design was a real-life longitudinal follow-up counseling intervention. Data were collected from November 2017 to May 2020. The nurse-led intervention and patients’ follow-up time was one year. Of the 78 patients recruited, 74 completed the study. The most significant findings were in the levels of total cholesterol, low-density lipoprotein cholesterol and trigly…

HP-Xe to go: Storage and Transportation of Hyperpolarized 129-Xe

2016

Abstract Recently the spin–lattice relaxation time T 1 of hyperpolarized (HP)- 129 Xe was significantly improved by using uncoated and Rb-free storage vessels of GE180 glass. For these cells, a simple procedure was established to obtain reproducible wall relaxation times of about 18 h. Then the limiting relaxation mechanism in pure Xe is due to the coupling between the nuclear spins and the angular momentum of the Xe–Xe van-der-Waals-molecules. This mechanism can be significantly reduced by using different buffer gases of which CO 2 was discovered to be the most efficient so far. From these values, it was estimated that for a 1:1 mixture of HP-Xe with CO 2 a longitudinal relaxation time of …

Prosocial development from childhood to adolescence: a multi-informant perspective with Canadian and Italian longitudinal studies.

2009

Objectives:  To longitudinally describe prosocial behaviour development from childhood to adolescence, using multiple informants within Canadian and Italian samples. Method:  Participants in Study 1 were 1037 boys from low socioeconomic status (SES) areas in Montreal, Canada, for whom yearly teacher and mother reports were obtained between the ages of 10 and 15. Participants in Study 2 were 472 children (209 girls) from Genzano, Italy, for whom yearly self and teacher reports were obtained between the ages of 10 and 14. Developmental trajectories were estimated from ratings by each informant to identify subgroups of children following distinct courses of prosocial development. Results:  In …

Reading and Spelling Development Across Languages Varying in Orthographic Consistency: Do Their Paths Cross?

2020

We examined the cross‐lagged relations between reading and spelling in five alphabetic orthographies varying in consistency (English, French, Dutch, German, and Greek). Nine hundred and forty‐one children were followed from Grade 1 to Grade 2 and were tested on word and pseudoword reading fluency and on spelling to dictation. Results indicated that the relations across languages were unidirectional: Earlier reading predicted subsequent spelling. However, we also found significant differences between languages in the strength of the effects of earlier reading on subsequent spelling. These findings suggest that, once children master decoding, the observed differences between languages are not…
