Effortful control,negative emotionality,and juvenile recidivism: an empirical test of DeLisi and Vaughn’s temperament-based theory of antisocial behavior

Recently, DeLisi and Vaughn articulated a temperament-based theory of antisocial behavior which they expressed as the first within criminology to use temperament explicitly, and as the exclusive explanatory construct of both antisocial behavior and negative interactions with the criminal justice system. We provide an initial empirical test of the theory’s two main constructs of effortful control (EC) and negative emotionality (NE) with respect to juvenile offending using a sample of 27,712 adjudicated youth. Cox regressions reveal youth with lower levels of EC and those with higher NE re-offend faster, controlling for demographics plus many prominent risk factors. Furthermore, the approximately 5% of youth at the extreme ends of both low EC and high NE evidence higher recidivism rates and faster time to failure. The findings show strong initial support for temperament theory, and we discuss relevancy for future research, prevention and intervention.     

Report: increases in police use of force in the presence of body-worn cameras are driven by officer discretion: a protocol-based subgroup analysis of ten randomized experiments

Objectives

Our multisite randomized controlled trial reported that police body-worn cameras (BWCs) had, on average, no effect on recorded incidents of police use of force. In some sites, rates of use of force decreased and in others increased. We wanted to understand these counter-intuitive findings and report pre-specified subgroup analyses related to officers’ discretion on activating the BWCs.

Methods

Using pre-established criteria for experimental protocol breakdown in terms of treatment integrity, ten experimental sites were subgrouped into “high-compliance” (no officer discretion applied to when and where BWCs should be used; n?=?3), “no-compliance” (treatment integrity failure in both treatment and control conditions; n?=?4), and tests where officers applied discretion during treatment group but followed protocol in control conditions only (n?=?4).

Results

When officers complied with the experimental protocol and did not use discretion, use of force rates were 37 % lower [SMD?=?(?.346); SE?= .137; 95?% CI (?.614) – (?.077)]; when officers did not comply with treatment protocol (i.e., officers chose when to turn cameras on/off), use of force rates were 71 % higher [SMD?= .392; SE?= .130; 95?% CI (.136) – (.647)], compared to control conditions. When full discretion (i.e., overall breakdown of protocol) was applied to both treatment and control conditions, null effects were registered [SMD?= .009; SE=.070; 95?% CI (?.127) – (.146)], compared to control conditions.

Conclusions

BWCs can reduce police use of force when then officers’ discretion to turn cameras on or off is minimized—in terms of both case types as well as individual incidents. BWCs ought to be switched on and the recording announced to suspects at early stages of police–public interactions. Future BWCs tests should pay close attention to adherence to experimental protocols.

     

A meta-analysis update on the effectiveness of early self-control improvement programs to improve self-control and reduce delinquency

Objective

To update Piquero et al.’s (Justice Quarterly 27:803–834, 2010) meta-analysis on early self-control improvement programs.

Methods

Screening of eligible studies was carried out for the period between January 2010 and September 2015. An additional seven studies were identified, which were added to the original database of 34 studies, totaling an overall sample of 41 eligible studies. A random effects model was used to obtain an overall mean effect size estimate. Additional analyses were performed to assess publication bias and moderation.

Results

Overall average, positive, and significant effect sizes were observed for improving self-control (0.32) and reducing delinquency (0.27). There was evidence of publication bias for the self-control improvement outcomes, as well as some evidence of moderation for both self-control improvement and delinquency outcomes.

Conclusions

Early self-control improvement programs are an effective evidence-based strategy for improving self-control and reducing delinquency.

     

A meta-analysis update on the effects of early family/parent training programs on antisocial behavior and delinquency

Objective

To update Piquero et al.’s meta-analysis on early family/parent training programs.

Methods

Screening of eligible studies was carried out for the period between January 2008 and August 2015. An additional 23 studies were identified, which were added to the original database of 55 studies, totaling an overall sample of 78 eligible studies. A random-effects model was used to obtain an overall mean effect size estimate. Additional analyses were performed to assess publication bias and moderation.

Results

An overall average, positive, and significant effect size of 0.37 was calculated, which corresponds to 32 out of 100 in a treated group versus 50 out of 100 in a control group who offended. There was some evidence of publication bias and moderation.

Conclusions

Early family/parent training programs are an effective evidence-based strategy for preventing antisocial behavior and delinquency.

Romantic partners and young adult offending: Considering the role of partner's socioeconomic characteristics

In this study, we examined whether and to what extent the effects on offending of marriage and different types of cohabitating partnerships depend on the romantic partner's socioeconomic status (SES). Such research addresses a key gap in knowledge regarding potential heterogeneity of effects on behavior of romantic partnerships. Drawing on the National Longitudinal Survey of Youth 1997, we examined the within‐individual effects of three romantic partner's socioeconomic characteristics–education, employment, and income–on offending from ages 18 to 34. Results revealed that marriage was related to reductions in arrest only for those whose spouse was employed (full or part time) and had income. In contrast to marriage, partner SES was not related to arrest among those who cohabited with a partner they never married. Additionally, partner SES was often associated with reductions in arrest among those who cohabited with a partner they later married, but the reductions were statistically indistinguishable across levels of partner SES. Lastly, these effects were experienced similarly for low‐ and high‐SES individuals alike, and no gender differences were detected in these effects. Our findings suggest that important life events such as marriage and cohabitation can be behavior‐altering transitions, but the effects of these events are variable.
