“…Further, no association between the cortisol:cortisone ratio, as a measure of placental 11 beta hydroxysteroid dehydrogenase, and birthweight was noted in healthy women; however, a positive relation was noted in women with mental health problems . High buffers of stress have been associated with lower rates of corticotrophin reactive hormone . Needless to say, the present findings must be interpreted with some caution, as residual confounding of other, non‐measured, lifestyle factors such as diet and physical activity may account for the association.…”

Introduction Neighborhood deprivation has been associated with adverse perinatal outcomes but it is unclear to what extent maternal and social risk factors explain the association and how a stressful environment per se contributes. Material and methods A population‐based register study including 218 030 deliveries in Sweden between January 2013 and July 2017 was conducted. Exposure was living in a deprived or severely deprived area defined by the National Operations Department of the Swedish Police Authority. Adverse perinatal outcomes included preterm births, small‐for‐gestational‐age births and stillbirths. A propensity score‐based method was used to control for individual baseline characteristics. Associations were investigated with logistic regression analyses and risk estimates are presented as crude (OR) and adjusted odds ratio (aOR) with 95% confidence interval (CI). Results Living in a deprived neighborhood in Sweden was associated with extremely preterm births (deprived area OR 1.50, 95% CI 1.07‐2.11, severely deprived OR 1.90, 95% CI 1.40‐2.58), small‐for‐gestational‐age birth (deprived OR 1.45, 95% CI 1.31‐1.60, severely deprived OR 1.85, 95% CI 1.69‐2.03) and stillbirth (deprived OR 1.62, 95% CI 1.17‐2.26, severely deprived OR 1.56, 95% CI 1.11‐2.19). After accounting for individual maternal and social risk factors, the risk of small for gestational age in severely deprived areas remained (aOR 1.45, 95% CI, 1.19‐1.75). Conclusions The contextual effect of living in a deprived neighborhood on the risk of extremely preterm births, small‐for‐gestational‐age births and stillbirths was to a high extent explained by individual factors of women residing in exposed areas, yet remained for small‐for‐gestational‐age births in severely deprived areas after adjustment for maternal and social risk factors.

“…However, females and males reported highest on the same three items; 1 “You feel rested”, 8 “You are tired” and 13 “You are full of energy”, all with reversed indexes. Further psychometric studies might investigate more systematically, which are the most informative and necessary PSQ items in adolescent samples, for example by use of Item Response Theory (IRT) models (Borders et al, 2017 ).…”

Psychometric Properties of the Perceived Stress Questionnaire (PSQ) in 15–16 Years Old Norwegian Adolescents

2018

A better understanding about prerequisites of health and well-being in adolescents is important to prevent chronicity and comorbidities of stress and to improve health promotion in this group. For this purpose, useful instruments are required. The Perceived Stress Questionnaire (PSQ) is developed for research, with an emphasis on predictive validity. The PSQ comprises different components of stress, and the instrument might be useful in studying prerequisites and predictors of health and well-being in adolescents. However, the instrument has not been evaluated in Norwegian psychosomatic populations and in adolescents. Moreover, the factor structure of the PSQ seems to vary between populations, and invariance across gender and concurrent validity regarding mindfulness are not previously tested. The objective of this study were to evaluate the psychometric properties of the Norwegian version of the PSQ in adolescents, including evaluate the fit of previously proposed PSQ-models in females and males and test measurement invariance across gender. Concurrent validity with respect to mindfulness (Mindful Attention Awareness Scale- Adolescent [MAAS-A]) was preliminary evaluated. Confirmatory factor analysis for each previously proposed model was conducted, separately for females and males. Multi-group factor analyses were performed to test measurement invariance of the different PSQ-models across gender. The associations between the PSQ and the MAAS-A and inter-scale correlations were preliminary evaluated. Preceding the data collection and main analyses, the instruments were translated to Norwegian following standardized procedures. The participants in study were Norwegian adolescents aged 15–16 years (N = 524). The overall PSQ performance seemed to correspond to previous findings, and internal consistency was supported across gender. A four-factor model of the PSQ showed best fit to the data in both females and males and configural and metric invariance seemed supported. Full scalar invariance was not supported for the four-factor model, implying that cross-group comparisons (between females and males) on latent means may be uncertain and must be interpreted with caution. Concurrent validity with respect to mindfulness (MAAS-A) was preliminary supported. Further studies might be needed to confirm the findings from this study.

“…The IRT likelihood ratio model was used for differential item functioning (DIF), and differential test functioning (DTF) analyses. The Rasch method was also used in different fields [5]. Depressive and anxiety symptoms in refugees were evaluated with the help of IRT [6].…”

“…All questions were on the same scale with similar direction, from "strongly agree" to "strongly disagree". The scale had the following alternatives: strongly agree (1), agree (2), undecided (3), disagree (4), strongly disagree (5). For instance, based on Table 1, feeling frustrated and angry were some of the feelings that respondents agreed most strongly that they experienced while facing delays of rail transport.…”

An Item Response Theory to Analyze the Psychological Impacts of Rail-Transport Delay

Questionnaire instruments have been used extensively by researchers in the literature review for evaluation of various aspects of public transportation. Important implications have been derived from those instruments to improve various aspects of the transport. However, it is important that instruments, which are designed to measure various stimuli, meet criteria of reliability to reflect a real impact of the stressors. Particularly, given the diverse range of commuter characteristics considered in this study, it is necessary to ensure that instruments are reliable and accurate. This can be achieved by finding the relationship between the item’s properties and the underlying unobserved trait, being measured. The item response theory (IRT) refers to measurement of an instrument’s reliability by examining the relationship between the unobserved trait and various observed items. In this study, to determine if our instrument suffers from any potentially associated problems, the IRT analysis was conducted. The analysis was employed based on the graded response model (GRM) due to the ordinal nature of the data. Various aspects of the instruments, such as discriminability and informativity of the items were tested. For instance, it was found while the classical test theory (CTT) confirm the reliability of the instrument, IRT highlight some concerns regarding the instrument. Also, the person fit assessment measure, for instance, highlights some concern regarding respondents answering some of the questions due to lack of interest, choosing answers randomly. Not many studies have examined instruments’ reliability in determining the psychological impacts of public transportation on commuters in the way that was performed here.
