Prevention of Problem Behavior Through Annual Family Check-Ups in Early Childhood: Intervention Effects From Home to Early Elementary School

This randomized intervention trial examined the effects of yearly Family Check-Ups (FCUs) and tailored parent management training on parent report of problem behavior from age 2 to 5 years and teacher report of oppositional behavior at age 7.5. A multiethnic risk sample of 731 families in 3 distinct geographical settings who were receiving assistance from the Women, Infants, and Children Nutritional Supplement (WIC) program were randomly assigned to a yearly FCU. Intention to treat (ITT) analyses were used to examine overall intervention effects, and complier average causal effect (CACE) modeling was used to examine the effects of annual intervention engagement in the FCU on parent reports of child problem behavior from age 2 to 5 and teacher reports of problem behavior at age 7.5. ITT intervention effects were found regarding parent report at ages 2 to 5 and teacher report at age 7.5, indicating less growth in problem behavior for children in the intervention group than for those in the control group. CACE modeling of intervention engagement revealed that the effect sizes on parent- and teacher-reported problem behavior increased as a function of the number of yearly FCUs caregivers participated in. Findings suggest that embedding yearly FCU services within the context of social, health, and educational services in early childhood can potentially prevent early-onset trajectories of antisocial behavior. The increases in effect size with successive FCU engagement underscores the importance of a motivational approach to parenting support among high-risk families.     

Supporting child witnesses during identification lineups: Exploring the effectiveness of registered intermediaries

Performance at identification lineup was assessed in eighty‐five 6‐ to 11‐year‐old typically developing children. Children viewed a live staged event involving 2 male actors, and were asked to identify the perpetrators from 2 separate lineups (one perpetrator‐present lineup and one perpetrator‐absent lineup). Half the children took part in lineups adapted by a registered intermediary (an impartial, trained professional who facilitates understanding and communication between vulnerable witnesses and members of the justice system), and half took part in “best‐practice” lineups, according to the current guidance for eyewitness identification in England and Wales. Children receiving assistance from a registered intermediary (relative to children who received best‐practice lineups) were more accurate in their identifications for perpetrator‐present lineups, and there was some evidence that they were also more accurate for perpetrator‐absent lineups. This provides the first empirical evidence for the effectiveness of registered intermediary support during identification lineups.     

Limited effects of pre‐existing maternal antisocial behaviours on infant neurodevelopment: A pilot study

Antisocial behaviour disorders (ABDs) are among the most costly and treatment resistant of all psychiatric syndromes. Select neurodevelopmental abnormalities have been labelled a risk factor for ABDs, but it is unknown if maternal ABDs are associated with early neurodevelopmental abnormalities. This study tested whether infants of ABD mothers had more neurodevelopmental abnormalities than mothers with no psychiatric disorder (ND). Thirty‐nine pregnant women (49% with ABDs; 51% no psychiatric disorder) were recruited from the community. Infant neurodevelopment was assessed at ≤1 and 8 weeks using the Neonatal Behavioural Assessment Scale and at 16 weeks of age using the Bayley Scales of Infant and Toddler Development‐III. There was no significant group difference at ≤8 weeks. At 16 weeks, ABD mothers rated their infants higher on the Adapted Behaviours subscale, specifically on the leisure and self‐directed scales, when corrected for substance use and socio‐economic status. This pilot study found higher maternal ratings of Adapted Behaviours at 16 weeks, which may be due to unrealistic expectations about infant development.

Highlights

• Maternal Antisocial behaviour disorders (ABDs) do not impact early infant neurodevelopment at ≤ 8 weeks old as measured by standardized assessment.
• Mothers with ABDs view their infants at 16 weeks as better adapted than women without any psychiatric disorder.
• Specifically, mothers with ABDs reported their infants as better adapted on the leisure and self‐direction subscales of the Bayley Scales of Infant and Toddler Development‐III. This finding may be due to less knowledge about normal infant adaptive behavior.

     

Impact of Appointment Waiting Time on Attendance Rates at a Clinical Cancer Genetics Service

The increase in demand for clinical cancer genetics services has impacted the ability to provide services timeously. Given limited resources, this often results in extended appointment waiting times. Over the last 3 years, the Cancer Genetics Service at the National Cancer Centre Singapore has continued to experience a steady increase in demand for its service. Nevertheless, significant no-show rates have been reported. This study sought to determine whether an association exists between appointment waiting times and attendance rates. Data was gathered for all participants meeting inclusion criteria. Attendance rates and appointment waiting times were calculated. The relationship between mean waiting times for those who did and did not attend their scheduled appointments was evaluated using Welch’s t test and linear regression model. The results showed a significant difference in mean appointment waiting times between patients who did and did not attend (32.66 versus 43.50 days respectively; p?<?0.0001). Furthermore, patients who waited for longer than 37 days were significantly less likely to attend. No-show rates increased as the waiting time increased, at a rate of 19.60% per 20 days and 21.40% per 30 days. In conclusion, appointment waiting time is a significant predictor for patient attendance. Strategies to ensure patients receive an appointment within the necessary timeframe at the desired setting are important to ensure that individuals at increased cancer risk attend their appointments in order to manage their cancer risks effectively.

Less willing to pay but more willing to buy: How the elicitation method impacts the valuation of a promotion

Willingness to pay (WTP—how much one is willing to pay for something) and willingness to buy (WTB—whether one is willing to buy something at a given price) are two common methods to elicit valuations and normatively should yield the same valuation order between two options. However, this research finds that WTP and WTB can yield opposite valuation orders between the regular offer and the promotional offer of a product. Specifically, it demonstrate that, (a) if the valuation of a product is only elicited with WTP, consumers value the product less when it is offered with a price promotion than when it is not; (b) if the valuation of a product is only elicited with WTB, consumers value the product more when it is offered with a price promotion than when it is not; and (c) if the valuation of a product is first elicited with WTP and then elicited with WTB, consumers always value the product less when it is offered with a price promotion than when it is not. A value‐inference account is proposed for the above findings, according to which, consumers infer the value of a promoted product differently when the valuation is elicited only with WTP or only with WTB. Theoretically, this research extends prior literature on sales promotion, showing that the valuation of a promotion is subject to the elicitation method. Practically, this research suggests how to help consumers manage their purchase intentions for promoted products.
