BACKGROUND: Attention-deficit hyperactivity disorder (ADHD) is overrepresented among individuals seeking treatment for substance use disorders. We previously reported that treatment with extended release mixed amphetamine salts (MAS-XR) increased abstinence, compared to placebo, among patients with co-occurring ADHD and cocaine dependence. This secondary analysis investigates the temporal relationship between ADHD improvement and cocaine abstinence in the first six weeks of the trial...

Based on the characteristic of small scale enterprises, the improvement of occupational health and safety management system (OHSMS) needs an effective intervention. This study proposed a structural equation model and examined the relationships of perceived organization support for safety (POSS), person-organization safety fit (POSF), and proactivity safety behaviors with safety management, safety procedures and safety hazards identification. Data was collected from 503 employees of 105 Chinese high-risk small scale enterprises over six months...

BACKGROUND AND OBJECTIVES: A better understanding of the relationships between empathy and internalizing disorders is needed to plan therapeutic interventions for children and adolescents. Several studies have revealed positive relations of internalizing symptoms to personal distress and affective empathy. However, there is a lack of studies that take into account the multidimensional nature of anxiety in its relation to empathy. DESIGN: Structural equation modeling was used to test the moderated mediation model of the relations between empathy, depression and anxiety dimensions and the moderating role of gender on these associations in inpatient adolescents...

OBJECTIVE: Agreement between administrative and survey data has been shown to vary by the condition of interest and there is limited research dedicated to parental report of asthma among children. The current study assesses the concordance between parent-reported asthma from the National Health Interview Survey (NHIS) with Medicaid administrative claims data among linkage eligible children from the NHIS. METHODS: Medicaid Analytic eXtract (MAX) files from the Centers for Medicare & Medicaid Services (CMS) (years 2000-2005) were linked to participants of the NHIS (years 2001-2005)...

Many previous studies report simulation evidence that the goodness-of-fit test in covariance structure analysis or structural equation modeling suffers from the overrejection problem when the number of manifest variables is large compared with the sample size. In this study, we demonstrate that one of the tests considered in Browne (1974) can address this long-standing problem. We also propose a simple modification of Satorra and Bentler's mean and variance adjusted test for non-normal data. A Monte Carlo simulation is carried out to investigate the performance of the corrected tests in the context of a confirmatory factor model, a panel autoregressive model, and a cross-lagged panel (panel vector autoregressive) model...

Objective: Latino youth are disproportionately affected by pediatric obesity and consequently experience impaired health-related quality of life (HRQOL). Although many caregivers of Latino youth do not speak English fluently, no validated Spanish translations of obesity-specific HRQOL measures exist for this population. Therefore, non-English-speaking Latino parents have typically been excluded from analyses related to HRQOL. This study assesses the factor structure of a Spanish translation of a parent-report measure of obesity-specific HRQOL, Sizing Them Up, in a treatment-seeking sample of children with obesity...

Despite literature identifies aspects that might promote innovation, the relationship between the leadership style and nurses' innovative behavior still remains unclear, and little research has provided evidence of this. To help advance in knowledge of effects of leadership on nurses' innovative behavior, we researched the effect of altruistic leadership on nurses' innovative behavior. In addition, the mediating role of affiliative humor in the relationship between altruistic leadership and nurses' innovative behavior was examined...

Latino day laborers are a socially and economically marginalized immigrant population with a high risk of occupational injury. These workers confront multiple social, psychological, and environmental hardships that increase their risk for adverse health outcomes. How these stressors interact and influence work-related injuries in this population remains unclear. We conducted an exploratory study with 327 Latino day laborers who completed a community survey. We developed a structural equation model, using cross-sectional data to explore the relationships among socioeconomic status, situational and immigration stress, depression, work risk exposure, and occupational injury...

The aim is to describe the distribution of immune status (as captured by antibody level) on the basis of a within-host submodel for continuous waning and occasional boosting. Inspired by Feller's fundamental work and the more recent delay equation formulation of models for the dynamics of physiologically structured populations, we derive, for given force of infection, a linear renewal equation. The solution is obtained by generation expansion, with the generation number corresponding to the number of times the individual became infected...

The effects of biodiversity on ecosystem functions have been extensively studied, but little is known about the effects of ecosystem functions on biodiversity. This knowledge is important for understanding biodiversity-ecosystem functioning relationships. Desertification reversal is a significant global challenge, but the factors that play key roles in this process remain unclear. Here, using data sampled from areas undergoing desertification reversal, we identify the dominant soil factors that play a role in vegetation recovery with ordinary least squares and structural equation modelling...

The impact of implicit leadership theories on performance and the mechanism linking them have received insufficient theoretical and research attention. Drawing on Bandura's social cognitive theory, the present study contributes theory through examining the assertion that higher congruence between followers' implicit leadership theory and the characteristics of supervisors enhance job performance through higher quality of leader-member exchange and self-efficacy. Moreover, in the proposed model, attachment insecurity was considered as the antecedent of the congruence and leader-member exchange in addition to the moderator of the relationship between them...

Intrinsically disordered proteins and regions (IDPs / IDRs) are characterized by well-defined sequence-to-conformation relationships (SCRs). These relationships refer to the sequence-specific preferences for average sizes, shapes, residue-specific secondary structure propensities, and amplitudes of multiscale conformational fluctuations. SCRs are discerned from the sequence-specific conformational ensembles of IDPs. A vast majority of IDPs are actually tethered to folded domains (FDs). This raises the question of whether or not SCRs inferred for IDPs are applicable to IDRs tethered to folded domains...

School bullying is negatively associated with self-esteem, but psychological mediators of bullying have yet to be clarified. We examined regulatory emotional self-efficacy (RESE) as a possible mediator in the association between self-esteem and school bullying. A cross-sectional study of 995 adolescents was conducted in two middle schools of Xi'an. All of the participants completed the Chinese version of the School Bullying Experience Questionnaire (C-SBEQ), Self-Esteem Scale (SES), and Regulatory Emotional Self-Efficacy Scale (RESE)...

OBJECTIVES: Despite the unequivocal benefits of regular physical activity, many parents engage in lower levels of physical activity (PA) following the birth of a child. Drawing on the theory of planned behaviour (TPB) and health action process approach (HAPA), an integrative model was developed to examine variables predicting PA in parents of very young children. In addition, key beliefs related to PA intentions and behaviour among parents of very young children were investigated. DESIGN: A prospective-correlational design with two waves of data collection, spaced one week apart, was adopted...
