Reduction of police vehicle accidents through mechaniically aided supervision

Tachograph recorders were installed in 224 vehicles of a metropolitan police department to monitor vehicle operation in an attempt to reduce the rate of accidents. Police sergeants reviewed each tachograph chart and provided feedback to officers regarding their driving performance. Reliability checks and additional feedback procedures were implemented so that upper level supervisors monitored and controlled the performance of field sergeants. The tachograph intervention and components of the feedback system nearly eliminated personal injury accidents and sharply reduced accidents caused by officer negligence. A cost-benefit analysis revealed that the savings in vehicle repair and injury claims outweighed the equipment and operating costs.     

OPIOID ABSTINENCE REINFORCEMENT DELAYS HEROIN LAPSE DURING BUPRENORPHINE DOSE TAPERING

A positive reinforcement contingency increased opioid abstinence during outpatient dose tapering (4, 2, then 0 mg/day during Weeks 1 through 3) in non‐treatment‐seeking heroin‐dependent volunteers who had been maintained on buprenorphine (8 mg/day) during an inpatient research protocol. The control group (n = 12) received $4.00 for completing assessments at each thrice‐weekly visit during dose tapering; 10 of 12 lapsed to heroin use 1 day after discharge. The abstinence reinforcement group (n = 10) received $30.00 for each consecutive opioid‐free urine sample; this significantly delayed heroin lapse (median, 15 days).     

Parenting programs during adolescence: Outcomes from universal and targeted interventions offered in real‐world settings

The aim of this naturalistic study was to explore short and long‐term outcomes of five different group‐based parenting programs offered to parents of 10 to 17‐year‐olds. Three hundred and fifteen parents (277 mothers and 38 fathers) who had enrolled in a parenting program (universal: Active Parenting, COPE ; Connect; targeted: COMET ; Leadership training for parents of teenagers [LFT ]) answered questionnaires at three measurement waves (baseline, post‐measurement, and one‐year follow‐up). The questions concerned parenting style, parental mental health, family climate and adolescent mental health. Results revealed small to moderate changes in almost all outcome variables and in all parenting programs. Overall, parents in COMET reported the largest short and long‐term changes. No substantial differences in change were seen between the other programs. The results support the general effectiveness of parenting programs for parents of adolescents.     

Teaching children with autism spectrum disorder to tact olfactory stimuli

Research on tact acquisition by children with autism spectrum disorder (ASD) has often focused on teaching participants to tact visual stimuli. It is important to evaluate procedures for teaching tacts of nonvisual stimuli (e.g., olfactory, tactile). The purpose of the current study was to extend the literature on secondary target instruction and tact training by evaluating the effects of a discrete‐trial instruction procedure involving (a) echoic prompts, a constant prompt delay, and error correction for primary targets; (b) inclusion of secondary target stimuli in the consequent portion of learning trials; and (c) multiple exemplar training on the acquisition of item tacts of olfactory stimuli, emergence of category tacts of olfactory stimuli, generalization of category tacts, and emergence of category matching, with three children diagnosed with ASD. Results showed that all participants learned the item and category tacts following teaching, participants demonstrated generalization across category tacts, and category matching emerged for all participants.     

Adult Bullying and Primary and Secondary Psychopathic Traits: Insights from a Community Sample

This study aimed to: (a) comprehend the relationship between primary and secondary psychopathy variants and bullying behaviors in adults; (b) to test for mediation effects of the experiences of victimization in strengthening the bonds between bullying and psychopathy; and (c) to explore how far gender and psychopathic variants predict bullying. Results showed that psychopathy (both primary and secondary) and gender (male) significantly predicted bullying perpetrator behaviors. These same predictors were also significant in explaining total involvement with bullying; primary psychopathy displayed, however, better explanatory power. Being a victim of bullying also mediated the relationship between psychopathic variants and bullying perpetrating. The magnitude of the correlations between bullying and both psychopathic variants detected in this study were bigger than the average reported in studies with children and adolescents, which could inform about greater severity of these behaviors in adult life. Specifically, findings from regression analyses suggest that components of cold-blooded psychopathy could be driving the engagement of this sample with aggressive behaviors. Implications of these findings, along with limitations and directions for further research are discussed.     

Be a Mom: Formative Evaluation of a Web-Based Psychological Intervention to Prevent Postpartum Depression

A formative evaluation (consisting of two phases: a scoping literature review and a focus group with mental health professionals) was conducted to inform the design of a web-based intervention to prevent postpartum depression, in terms of its characteristics and content: the Be a Mom program. The results showed that the web-based intervention should be short-term, delivered postnatally, and grounded in cognitive-behavior therapy principles. Moreover, the intervention should include weekly sessions targeting basic contents: motherhood changes, reorganizations and emotional experience; cognitions, self-criticism, and self-compassion; parenting values, social support, and assertive communication skills; couple relationship, negotiation and conflict resolution skills; and postpartum depression signs and professional help-seeking. These results may improve the Be a Mom’s adequacy, implementation success, and effectiveness.     

Effects of primary task predictability and secondary task modality on lane maintenance

The objective of this work was to investigate the effects of auditory and visuo-spatial secondary tasks on variability in lane position in predictable and unpredictable driving conditions. Sixty-six participants drove a simulated vehicle. Predictability was manipulated by adding wind gusts, and the secondary task load by either an auditory task (Experiment 1) or a visuo-spatial task (Experiment 2). Results demonstrated that in the predictable driving condition, lane position variability decreased when auditory secondary task load was given, but it was not affected by visuo-spatial secondary task load. In the unpredictable driving condition; however, while the auditory secondary task load did not affect lane position variability, visuo-spatial secondary task load increased it. The data suggests that the effects of cognitive load on lane maintenance may depend on the type of the secondary task beside predictability of primary task.     

Crash avoidance and driver assistance technologies – Are they used?

Crash avoidance technologies have potential to mitigate collisions, and actual crash reductions have been identified for some systems. This study measured observed on-off rates of these technologies as an indicator of use, with a focus on lane maintenance systems (i.e., designed to keep vehicles within lanes by warning, braking, and/or steering) and studied factors that might increase their acceptance and use. Vehicles from nine manufacturers fitted with lane maintenance systems were observed at service departments during 2016. Systems were turned on in 51% of 983 vehicles. The activation rate was higher for systems with braking/steering interventions and vibrating warnings and decreased with total mileage. Large proportions of front crash prevention (93%), blind spot monitoring (99%), rear cross-traffic alert (97%), and driver monitoring alert (90%) systems were enabled, and most optional settings were set to factory defaults. Owner surveys linked to observations showed that drivers who had lane maintenance systems turned off believed warnings were distracting and unnecessary compared with drivers whose systems were on.
