“…Given the large percentage of missing data at the level of the care-giving unit, analysis relied on the 223 complete care-giving units. However, when data are not missing completely at random (as is most often the case), ignoring available information by limiting the analysis to complete units results in biased estimates that cannot be generalisable to the entire population from which families were sampled (Acock 2005; Blozis et al 2013; Schafer and Graham 2002). Therefore, an additional sensitivity analysis consisted of the entire sample (818 care-giving units), using multiple imputation to account for missing values (Asparouhov and Muthen 2010).…”

The present study evaluates a conceptual model of elder neglect within the home care arrangement that takes into consideration the older adult, his or her family members, and the home care worker. Data from 223 complete care-giving units, which consist of an older adult, a family member and a home care worker, were analysed using structural equation modelling. Overall, 31.5 per cent of the older adults, 18 per cent of the care workers and 32.3 per cent of the family members reported at least one type of elder neglect. The proposed model showed a reasonable fit to the data. There was an inverse effect from type of home care to family member's burden and elder neglect, with live-in (around the clock) care being associated with lower levels of family member burden and elder neglect compared with live-out Israeli home care (provided for several hours per week). The amount of informal assistance provided by family members was inversely related to the amount of burden reported by home care workers, with greater informal assistance being associated with lower levels of worker burden. The findings call for the important role of formal home care by demonstrating a potentially protective effect for live-in migrant home care. The study also emphasises the shared burden between formal and informal sources of care.

“…We also have numerous examples of child effects on a parent characteristic (e.g., Ahmadzadeh et al, 2019), although in the absence of a significant path from a birth parent variable to the child variable, we cannot determine whether these child effects are genetically mediated. We have sought to identify evocative rGE associations in some of our analyses and Adoption process Blozis et al (2013), Ge et al (2008), Martin et al (2011) Genetics and prevention Harold et al (2017), Leve (2017), Leve, Harold et al (2010), Leve et al (2018), , Reiss et al (2009) failed to detect a genetic signal. These null findings could be for several reasons, including: (a) we may not have identified or measured the relevant birth parent variable, including possible incongruence between an adult phenotype and a child phenotype, (b) evocative effects may not appear until later in child development, (c) evocative effects may be masked by interaction effects, as moderated mediation (see Fearon et al, 2015, as an example), (d) we only have birth father data for approximately one-third of our sample and thus are missing a portion of the potential genetic influences, (e) the child variables we have examined may not show intergenerational genetic transmission or (f) the genetic influences involved are nonadditive.…”

The Early Growth and Development Study (EGDS) is a prospective adoption study of birth parents, adoptive parents and adopted children (n = 561 adoptees). The original sample has been expanded to include siblings of the EGDS adoptees who were reared by the birth mother and assessed beginning at age 7 years (n = 217 biological children), and additional siblings in both the birth and adoptive family homes, recruited when the adoptees were 8–15 years old (n = 823). The overall study aims are to examine how family, peer and contextual processes affect child and adolescent adjustment, and to examine their interplay (mediation, moderation) with genetic influences. Adoptive and birth parents were originally recruited through adoption agencies located throughout the USA following the birth of a child. Assessments are ongoing and occurred in 9 month’s intervals until the adoptees turned 3 years of age, and in 1 to 2 year intervals thereafter through age 15. Data collection includes the following primary constructs: child temperament, behavior problems, mental health, peer relations, executive functioning, school performance and health; birth and adoptive parent personality characteristics, mental health, health, context, substance use, parenting and marital relations; and the prenatal environment. Findings highlight the power of the adoption design to detect environmental influences on child development and provide evidence of complex interactions and correlations between genetic, prenatal environmental and postnatal environmental influences on a range of child outcomes. The study sample, procedures and an overview of findings are summarized and ongoing assessment activities are described.

“…Third, the use of retrospective data about events that occurred in the past may have led to recall bias, distorting the results. Fourth, statistical analysis using FIML can involve bias when data are not missing at random, because it is based on the assumption of missing at random or missing completely at random [71]. Comparing values between the FIML method and the list-wise deletion method revealed that model fit indices for Positive reframing indicated not to retain good model fit, and the β coefficient on Venting in Brief COPE scores included zero in 95% CIs.…”

Background The present study used a third potential model with both in parallel and in series effects to identify mediators influencing the association between probable posttraumatic stress disorder (PTSD) and quality of life (QOL). In addition, we sought to clarify how stress-coping behaviors influence components of QOL. Methods Participants were 220 emergency service workers. PTSD was assessed using the Impact of Event Scale-Revised (IES-R). QOL was assessed using the MOS 36-Item Short-Form Health Survey (SF-36). Mediation analysis and moderated mediation analysis of interaction effects with a third potential model were used to examine the effects of stress-coping (Brief COPE scores), social support (Multidimensional Scale of Perceived Social Support [MSPSS] scores), and resilience (Connor-Davidson Resilience Scale [CD-RISC] scores) on the association between probable PTSD and QOL. Results The mediation analysis with confounders suggested an acceptable model fit. The moderated mediation analysis did not indicate differences in the moderators. IES-R scores were significantly positively associated with Active coping, Venting, and Positive reframing in Brief COPE scores and were significantly negatively associated with MSPSS scores. Active coping, Venting, and Positive reframing in Brief COPE and MSPSS scores was significantly positively associated with CD-RISC scores, which were significantly positively associated with SF-36 scores. A sensitivity analysis comparing the results between the full information maximum likelihood method and the list-wise deletion method indicated that the 95% confidence interval included zero and a good model fit was not maintained for indices of coping strategies in Venting and Positive reframing in Brief COPE scores. Conclusions Active coping in response to stressful situations is an important behavior for maintaining good mental health among emergency service workers. In addition, Active coping in stress-coping and social support may have strengthened participants’ resilience, and resilience may have improved QOL. However, Positive reframing and Venting might have confounded the results because they exhibited a Not Missing At Random data distribution. Screening of mental health and QOL should include simultaneous assessment of stress-coping, social support, and resilience. Although the present findings are suggestive, because this was a cross-sectional study, causal relationships between PTSD and QOL mediated by three mediators could not be confirmed.
