Background Parenting programs suitable for delivery at scale in low‐resource contexts are urgently needed. We conducted a randomized trial of Parenting for Lifelong Health (PLH) for Young Children, a low‐cost 12‐session program designed to increase positive parenting and reduce harsh parenting and conduct problems in children aged 2–9. Methods Two hundred and ninety‐six caregivers, whose children showed clinical levels of conduct problems (Eyberg Child Behavior Inventory Problem Score, >15), were randomly assigned using a 1:1 ratio to intervention or control groups. At t0, and at 4–5 months (t1) and 17 months (t2) after randomization, research assistants blind to group assignment assessed (through caregiver self‐report and structured observation) 11 primary outcomes: positive parenting, harsh parenting, and child behavior; four secondary outcomes: parenting stress, caregiver depression, poor monitoring/supervision, and social support. Trial registration: ClinicalTrials.gov (NCT02165371); Pan African Clinical Trial Registry (PACTR201402000755243); Violence Prevention Trials Register (http://www.preventviolence.info/Trials?ID=24). Results Caregivers attended on average 8.4 sessions. After adjustment for 30 comparisons, strongest results were as follows: at t1, frequency of self‐reported positive parenting strategies (10% higher in the intervention group, p = .003), observed positive parenting (39% higher in the intervention group, p = .003), and observed positive child behavior (11% higher in the intervention group, p = .003); at t2, both observed positive parenting and observed positive child behavior were higher in the intervention group (24%, p = .003; and 17%, p = .003, respectively). Results with p‐values < .05 prior to adjustment were as follows: At t1, the intervention group self‐reported 11% fewer child problem behaviors, 20% fewer problems with implementing positive parenting strategies, and less physical and psychological discipline (28% and 14% less, respectively). There were indications that caregivers reported 20% less depression but 7% more parenting stress at t1. Group differences were nonsignificant for observed negative child behavior, and caregiver‐reported child behavior, poor monitoring or supervision, and caregiver social support. Conclusions PLH for Young Children shows promise for increasing positive parenting and reducing harsh parenting.

“…Coefficient ω gives a better estimate of reliability than Cronbach’s α if the items of a scale are not tau equivalent [32, 33]. McDonald’s ωs were determined using the factor loadings of the multilevel confirmatory factor analysis (within-school factor models; only for the subscales with more than 2 items).…”

BackgroundPolicies, designed to promote resilience, and research, to understand the determinants and correlates of resilience, require reliable and valid measures to ensure data quality. The student resilience survey (SRS) covers a range of external supports and internal characteristics which can potentially be viewed as protective factors and can be crucial in exploring the mechanisms between protective factors and risk factors, and to design intervention and prevention strategies. This study examines the validity of the SRS.Methods7663 children (aged 11–15 years) from 12 local areas across England completed the SRS, and questionnaires regarding mental and physical health. Psychometric properties of 10 subscales of the SRS (family connection, school connection, community connection, participation in home and school life, participation in community life, peer support, self-esteem, empathy, problem solving, and goals and aspirations) were investigated by confirmatory factor analysis (CFA), differential item functioning (DIF), differential test functioning (DTF), Cronbach’s α and McDonald’s ω. The associations between the SRS scales, mental and physical health outcomes were examined.ResultsThe results supported the construct validity of the 10 factors of the scale and provided evidence for acceptable reliability of all the subscales. Our DIF analysis indicated differences between boys and girls, between primary and secondary school children, between children with or without special educational needs (SEN) and between children with or without English as an additional language (EAL) in terms of how they answered the peer support subscale of the SRS. Analyses did not indicate any DIF based on free school meals (FSM) eligibility. All subscales, except the peer support subscale, showed small DTF whereas the peer support subscale showed moderate DTF. Correlations showed that all the student resilience subscales were negatively associated with mental health difficulties, global subjective distress and impact on health. Random effects linear regression models showed that family connection, self-esteem, problem solving and peer support were negatively associated with all the mental health outcomes.ConclusionsThe findings suggest that the SRS is a valid measure assessing these relevant protective factors, thereby serving as a valuable tool in resilience and mental health research.Electronic supplementary materialThe online version of this article (doi:10.1186/s13034-016-0132-5) contains supplementary material, which is available to authorized users.

“…Una vez confirmada la solución factorial se evaluó la fiabilidad de los factores utilizando el Coeficiente alfa de Cronbach y el índice de homogeneidad ítem total, además considerando las limitaciones de este coeficiente (Dunn, Baguley, & Brunsden, 2014;Green & Yang, 2009;Revelle & Zinbarg, 2009;Sijtsma, 2009;Trizano-Hermosilla & Alvarado, 2016), dentro de las que se destaca el supuesto de tau-equivalencia o igualdad de saturaciones factoriales, el análisis de fiabilidad se verá complementado con el coeficiente omega (McDonald, 1999) entregando estimaciones más adecuadas de la fiabilidad al estimarse desde el modelo factorial.…”

ResumenEl propósito de esta investigación fue estudiar la equivalencia y estabilidad psicométrica de la Escala de Actitudes hacia la Autoridad Institucional (AAI-A) en adolescentes chilenos y colombianos. Se realizó un estudio de corte transversal en el que participaron dos muestras independientes de adolescentes de ambos sexos, de edades comprendidas entre 12 y 20 años. La primera muestra estuvo compuesta por 692 adolescentes chilenos, y la segunda por 541 adolescentes colombianos. Los resultados obtenidos mediante los procedimientos de validez cruzada, análisis factorial exploratorio y confirmatorio, análisis de invarianza factorial, los análisis correlacionales para evaluar la validez de criterio externo y los análisis de consistencia interna y homogeneidad, permiten concluir que la AAI-A es un instrumento válido y fiable en ambos contextos.Palabras clave: actitud hacia la autoridad, adolescencia, invarianza factorial AbstractThe objective of this research is to study the equivalence and psychometric stability of the scale of attitudes towards authority in Chilean and Colombian teenagers. We carried on a transversal study with two independent samples of teenagers from both gender, aged 12 to 20 years old. The first sample was composed of 692 Chilean teenagers and the second one was composed of 541 Colombian teenagers. The results obtained using cross-validation procedures, exploratory and confirmatory factor analysis, factorial invariance analysis, correlational analyzes to evaluate the validity of external criteria and analyzes of internal consistency and homogeneity allowed us to conclude that AAI-A is an instrument valid and reliable in both contexts.Keywords: attitude toward authority, adolescence, factorial invariance Agradecimientos: Este artículo reporta resultados parciales del proyecto FONDECYT N° 11150157 denominado "Dejando atrás los modelos centrados en el déficit: desarrollo de un modelo estructural para explicar el clima social escolar.
