When and how to survey potential respondents is often determined by budgetary and external constraints, but choice of survey modality may have enormous implications for data quality. Different survey modalities may be differentially susceptible to measurement error attributable to interviewer assignment, known as interviewer effects. In this paper, we leverage highly similar surveys, one conducted face-to-face (FTF) and the other via phone, to examine variation in interviewer effects across survey modality and question type. We find that while there are no cross-modality differences for simple questions, interviewer effects are markedly higher for sensitive questions asked over the phone. These findings are likely explained by the enhanced ability of in-person interviewers to foster rapport and engagement with respondents. We conclude with a thought experiment that illustrates the potential implications for power calculations, namely, that using FTF data to inform phone surveys may substantially underestimate the necessary sample size for sensitive questions.

Behaviour change communication (BCC) remains a central component of the interventions used in the fight against malaria in Ghana. However, there is limited evidence of its effectiveness. This study evaluated the effects of BCC strategies on knowledge (symptoms, causes and prevention) and overall knowledge of malaria among Ghanaian women aged 15-49 years. The propensity score matching (PSM) approach and logistic regression were used to analyse data from the 2016 edition of the Malaria Indicator Survey (MIS). Women who participated in community-level education or heard/saw media messages on malaria, or both, had significantly more knowledge of the disease than women who lacked access to any of these mediums of communication. The effect of these strategies on women's overall knowledge of malaria is about 2% to 4% and is higher on their knowledge of the symptoms (3% to 6%) and prevention (2% to 4%) than the causes (2%). The combined effects of both mediums of communication are relatively higher than the effect of either of them as a single medium of communication. Further analysis showed that improved knowledge of the disease is associated with higher preventive measures taken by women for themselves and for their children. The results are more significant in rural and poor households than in urban and non-poor households. These findings underscore the need for the Ministry of Health and its partner institutions to adopt an innovative approach which combines the two strategies in intensively educating Ghanaians, and women in particular, on the symptoms and prevention of malaria, giving due cognisance to households' socioeconomic status and geographical location.

Unfolding item response theory (IRT) models are important alternatives to dominance IRT models in describing the response processes on self-report tests. Their usage is common in personality measures, since they indicate potential differentiations in test score interpretation. This paper aims to gain a better insight into the structure of trait personality, by investigating whether the dominance or alternatively the unfolding IRT model are better descriptors of the response processes on a personality measure constructed under the dominance response theorem. For the assessment of the dominant model, the Graded Response Model (GRM) is used; while for the unfolding model, the Generalized Graded Unfolding Model (GGUM) was examined. All analyses are conducted with the freely available R. A sample of 1340 Greek adults, employed in private and public organizations, fulfilled the Trait Personality Questionnaire 5 short-form (TPQue5). Findings contradict previous research on trait personality. In accordance to the construction method employed, the TPQue5 items are best understood by monotonically increasing item response functions (IRFs). Individuals responding to the TPQue5 increase their probability of endorsing its items as their trait level increases; this stands for all personality dimensions, although Openness to Experience exhibited mixed type of item response patterns. Further research directions, implications and limitations are also discussed.

When planning a cluster randomized trial, evaluators often have access to an enumerated cohort representing the target population of clusters. Practicalities of conducting the trial, such as the need to oversample clusters with certain characteristics in order to improve trial economy or support inferences about subgroups of clusters, may preclude simple random sampling from the cohort into the trial, and thus interfere with the goal of producing generalizable inferences about the target population. We describe a nested trial design where the randomized clusters are embedded within a cohort of trial-eligible clusters from the target population and where clusters are selected for inclusion in the trial with known sampling probabilities that may depend on cluster characteristics (e.g., allowing clusters to be chosen to facilitate trial conduct or to examine hypotheses related to their characteristics). We develop and evaluate methods for analyzing data from this design to generalize causal inferences to the target population underlying the cohort. We present identification and estimation results for the expectation of the average potential outcome and for the average treatment effect, in the entire target population of clusters and in its non-randomized subset. In simulation studies, we show that all the estimators have low bias but markedly different precision. Cluster randomized trials where clusters are selected for inclusion with known sampling probabilities that depend on cluster characteristics, combined with efficient estimation methods, can precisely quantify treatment effects in the target population, while addressing objectives of trial conduct that require oversampling clusters on the basis of their characteristics.

This research aims to investigate information asymmetry in e-commerce supply chain channels and the impact of the fair preference model on the behavior and returns of channel members. Therefore, by contrasting it with the model in the completely rational case, this research establishes a more realistic principal-agent model and incorporates the fair preference model into the e-commerce supply chain channel. According to the model's analysis, the effort level of the retailer at each stage is positively correlated with the e-commerce efficiency coefficient, and the incentive coefficient of manufacturers is positively correlated with the e-commerce efficiency coefficient in the case where all rationality is assumed. Manufacturing companies' anticipated profits are positively correlated with the e-commerce efficiency coefficient. According to the fair preference model, retailers will put forth more effort to sell products when their fixed income from manufacturers is higher and their optimal effort level is positively correlated with that income. When e-commerce's efficiency coefficient is higher than 1, the retailer's revenue and effort exceeded those of traditional channels. Manufacturers and retailers both experience Pareto improvements in their earnings after the fair preference model is introduced.

Regardless of compliance to coercion by an alleged perpetrator, child maltreatment is abuse in any form. However, the extent to which coercion is described as an obligation (mandatory compliance) or permission (optional compliance) is legally relevant. The present investigation examined how attorneys question children about coercion and how children describe coercion in courtroom investigations of alleged child sexual abuse, and whether such language influences jurors' perceptions of children's testimony. Study 1 assessed 64 transcripts of children's testimonies and revealed that both attorneys and children use coercive language. Problematically, terms of permission were used when describing sexual abuse, potentially implying compliance was optional. Study 2 presented 160 adults with transcript excerpts, varied by coercive language (obligation or permission) and maltreatment type (sexual abuse or punishment). Coercive language influenced perceptions of coercion and whether the adult was to blame. Maltreatment type influenced perceptions of severity, credibility, and verdict. Overall, coercive language and maltreatment type influence perceptions of how the event unfolded.

Earlier reviews to discover research on interventions for children after neglect have concluded little was available, despite the well-documented prevalence and harmful effects of neglect on children. We revisited this question through a systematic literature review to discover the state of research on interventions for children who have experienced neglect. We searched MEDLINE, PsycINFO, ERIC, Sociological Abstracts and EMBASE for studies published between 2003 and 2021. Studies were included if neglect could be distinguished, and child outcomes reported. Eight reports describing six studies about six interventions were identified. These studies differed in interventions, age-groups, definitions of neglect, and outcomes. Four studies reported positive child outcomes though with varying degree of quality. More research is needed to inform a coherent theory of change following neglect. There remains an urgent need for research on interventions to help children recover from neglect.

Female offenders released from prison often face challenges within the community such as lack of employment, inconsistent attendance in substance use treatment, and complying with parole and probation conditions, which typically decreases their self-efficacy and motivation to refrain from reoffending. Despite this, much is still unknown of psychological factors that could impact female offenders' attitudes toward self-efficacy, such as mental illness symptoms, Adverse Childhood Experiences (ACEs), and personality differences. Thus, this cross-sectional study explored whether mental illness symptoms, ACEs, and personality differences were associated with attitudes toward self-efficacy (N = 398). Results suggest that mental illness symptoms, ACEs, and neuroticism negatively associated with attitudes toward self-efficacy in contrast to extraversion and conscientiousness. Parole/probation reentry and therapeutic implications are discussed.

Economic support programs for low-income families may play an important role in preventing child abuse and neglect. In the United States, childcare subsidies are provided to low-income families who meet certain requirements to offset the high cost of childcare. States have flexibility in setting many policies related to the provision of childcare subsidies, which results in a great deal of variation in how the programs operate between states. One policy dimension on which states vary is the number of employment hours required to receive childcare subsidies. A small body of work has begun to investigate the ways in which these state policy variations might relate to child maltreatment. Using 11 years of administrative data from the United States, the current study sought to estimate the relationship between two sources of variation in childcare subsidy policies: employment requirements and copayment size; and child neglect, physical abuse, and emotional abuse substantiations. The study found a nuanced relationship between required employment and neglect substantiations. Specifically, requiring some level of work was not associated with neglect substantiations, but requiring 30 hours of employment was associated with higher rates. The study did not find a relationship between copayment size and maltreatment substantiations.

Precise estimates of the impact of famine on infant and child mortality are rare due to lack of representative data. Using vital statistics reports on the Netherlands for 1935-47, we examine the impact of the Dutch famine (November 1944 to May 1945) on age-specific mortality risk and cause of death in four age groups (stillbirths, <1 year, 1-4, 5-14) in the three largest famine-affected cities and the remainder of the country. Mortality during the famine is compared with the pre-war period January 1935 to April 1940, the war period May 1940 to October 1944, and the post-war period June 1945 to December 1947. The famine's impact was most visible in infants because of the combined effects of a high absolute death rate and a threefold increase in proportional mortality, mostly from gastrointestinal conditions. These factors make infant mortality the most sensitive indicator of famine severity in this setting and a candidate marker for comparative use in future studies.
