Impulsivity: four ways five factors are not basic to addiction

Several impulsivity-related models have been applied to understanding the vulnerability to addiction. While there is a growing consensus that impulsivity is multifaceted, debate continues as to the precise number of facets and, more critically, which are most relevant to explaining the addiction-risk profile. In many ways, the current debate mirrors that which took place in the personality literature in the early 1990s (e.g., Eysenck's 'Big Three' versus Costa and McCrae's 'Big Five'). Indeed, many elements of this debate are relevant to the current discussion of the role of impulsivity in addictive behavior. Specifically, 1) the use of factor analysis as an atheoretical 'truth-grinding machine'; 2) whether additional facets add explanatory power over fewer; 3) the delineation of specific neurocognitive pathways from each facet to addictive behaviors, and; 4) the relative merit of 'top-down' versus 'bottom-up' approaches to the understanding of impulsivity. Ultimately, the utility of any model of impulsivity and addiction lies in its heuristic value and ability to integrate evidence from different levels of analysis. Here, we make the case that theoretically-driven, bottom-up models proposing two factors deliver the optimal balance of explanatory power, parsimony, and integration of evidence.

Improving family functioning and child outcome in methadone maintained families: the parents under pressure programme

t Societal responses to the existence of substance misuse fluctuate between harm minimisation and prohibition. Both approaches are predominantly downstream reactions to substance misuse that focus on the supply of harmful substances and the containment of misuse through treatment, rehabilitation or punishment. Until recently, little attention has been paid to the upstream individual, family, relationship, community or societal antecedents of substance misuse (which often overlap with those for other adverse life outcomes, such as unemployment, antisocial personality disorder and mental health problems) that have operated during earlier life. A growing body of evidence highlights the overlapping biological and experiential antecedents for substance abuse and other poor outcomes as well as the trajectory-changing protective factors that can prevent risks being translated into destiny. Risk minimisation and protection enhancement embedded in family and social systems are the essential building blocks of a set of early intervention strategies that begin antenatally and continue through the developing years of childhood, adolescence and young adult life, that have been shown to be effective in improving many outcomes in development, health and well-being. Much remains to be done to enable the promise of effective universal and targeted early intervention to be translated into policies, programs and practices that could be life-changing for citizens bogged in the mire of substance misuse and their children. Realistic, timely investment, influenced by the best scientific evidence indicating what works, for whom, under what circumstances, an increased degree of collaboration within and between governments and their agencies to enable "whole of government" responses in partnership with community-based initiatives are essential along with investments in multidisciplinary program evaluation research that will enable evidence-informed policy decisions to be tailored to the needs of individual countries.

A randomized controlled trial and economic evaluation of the Parents Under Pressure Program for parents in substance abuse treatment

Background There is growing interest in the provision of parenting support to substance misusing parents. Methods This pragmatic, multi-center randomized controlled trial compared an intensive one-to-one parenting program (Parents under Pressure, PuP) with Treatment as Usual (TAU) in the UK. Parents were engaged in community-based substance misuse services and were primary caregivers of children less than 2.5 years of age. The primary outcome was child abuse potential, and secondary outcomes included measures of parental emotional regulation assessed at baseline, 6 and 12-months. A prospective economic evaluation was also conducted. Results Of 127 eligible parents, 115 met the inclusion criteria, and subsequently parents were randomly assigned to receive PuP (n = 48) or TAU (n = 52). Child abuse potential was significantly improved in those receiving the PuP program while those in TAU showed a deterioration across time in both intent-to-treat (p < 0.03) and per-protocol analyses (p < 0.01). There was also significant reliable change (recovery/improvement) in 30.6% of the PuP group compared with 10.3% of the TAU group (p < 0.02), and deterioration in 3% compared with 18% (p < 0.02). The probability that the program is cost-effective was approximately 51.8% if decision-makers are willing to pay £1000 for a unit improvement in the primary outcome, increasing to 98.0% at a £20,000 cost-effectiveness threshold for this measure. Conclusions Up to one-third of substance dependent parents of children under 3-years of age can be supported to improve their parenting, using a modular, one-to-one parenting program. Further research is needed

Personality, cognition and hazardous drinking: support for the 2-Component Approach to Reinforcing Substances Model

Personality and cognitive processes are both related to alcohol use and misuse. A recent model of hazardous drinking referred, the 2-CARS model, postulates two major pathways to hazardous drinking. One pathway primarily involves the association between Reward Drive and Positive Outcome Expectancies, the second involves the association between Rash Impulsiveness and Drinking Refusal Self-Efficacy. In previous tests of the model, Drinking Refusal Self-Efficacy was found to have the most proximal impact on drinking, being directly influenced by Rash Impulsiveness, and indirectly influenced by Reward Drive through Positive Outcome Expectancies. The aim of the current study was to test the 2-CARS model in a larger independent sample. Results found that individuals with a strong Reward Drive showed higher Positive Outcome Expectancies, while individuals high in Rash Impulsiveness were more likely to report reduced Drinking Refusal Self-Efficacy. The present results also showed a theoretically unexpected pathway with a direct association between Rash Impulsiveness and Positive Outcome Expectancies. However, overall the results support the view that a greater understanding of hazardous drinking can be achieved by investigating the relationship between these personality and cognitive variables.

Predicting posttraumatic stress disorder after childbirth

Objective: around 50% of women report symptoms that indicate some aspect of their childbirth experience was 'traumatic', and at least 3.1% meet diagnosis for PTSD six months post partum. Here we aimed to conduct a prospective longitudinal study and examine predictors of birth-related trauma - predictors that included a range of pre-event factors - as a first step in the creation of a screening questionnaire. Method: of the 933 women who completed an assessment in their third trimester, 866 were followed-up at four to six week post partum. Two canonical discriminant function analyses were conducted to ascertain factors associated with experiencing birth as traumatic and, of the women who found the birth traumatic, which factors were associated with those who developed PTSD. Findings: a mix of 16 pre-birth predictor variables and event-specific predictor variables distinguished women who reported symptoms consistent with trauma from those who did not. Fourteen predictor variables distinguished women who went on to develop PTSD from those who did not. Conclusions: anxiety sensitivity to possible birthing problems, breached birthing expectations, and severity of any actual birth problem, predicted those who found the birth traumatic. Prior trauma was the single most important predictive factor of PTSD. Evaluating the utility of brief, cost-effective, and accurate screening for women at risk of developing birth-related PTSD is suggested

The reinforcement sensitivity theory of personality in children: A new questionnaire

We report the development of a self-report questionnaire of the reinforcement sensitivity theory (RST) of personality for use with children. Focus groups were held with children to sample their experiences of situations modelled on components of three RST systems: fight-flight-freeze system (FFFS, related to fear), behavioural inhibition system (BIS, related to anxiety), and behavioural approach system (BAS, related to approach). The thematic responses formed the conceptual anchors to the development of test items that were examined using exploratory factor analysis in a sample of 288 9–13 year olds. After eliminating items that did not load on their designated factor, or substantially cross-loaded over factors, the original 48 items were reduced to 21 items: 7 items for each of the BIS, FFFS and BAS factors. The separation of the BIS and FFFS items across two factors is consistent with the revised model of RST. We offer this new questionnaire as a RST measure of fundamental motivation and emotion traits in children

The Parents under Pressure parenting programme for families with fathers receiving treatment for opioid dependency: the PuP4Dads feasibility study

Background: The impact of parental drug use on children is a major public health problem. However, opioid-dependent fathers have been largely ignored in parenting research. Objective: Implement and test the feasibility and acceptability of the ‘Parents under Pressure’ parenting programme for opioid-dependent fathers and their families (PuP4Dads) and determine whether a full scale evaluation could be conducted. Design: Mixed methods feasibility study. Setting: Two non-NHS family support services for parents who use drugs in Scotland. Participants: Fathers prescribed Opioid Substitution Therapy (n=25), their partners (n=17) and children; practitioners; supervisors, service managers; referrers. Intervention: Home-visiting programme, including an integrated theoretical framework, case formulation, collaborative goal setting, and modules designed to improve parenting, the caregiving environment and child welfare. Delivered flexibly over six months by accredited practitioners. Main outcome measures: Feasibility progression criteria: recruitment target (n=24 fathers); acceptability of PUP; father engagement in the study (66% complete programme; minimum 10 complete baseline and post-treatment interviews); engagement in qualitative interviews (fathers n=10 minimum; practitioners 90% uptake; managers 80% uptake); focus groups (referrers 80% uptake); adequate fidelity; no adverse events. Data sources: Researcher administered validated questionnaires: Brief Child Abuse Potential; Parenting Sense of Competence; Difficulties in Emotion Regulation; Paternal/Maternal Antenatal Attachment; Emotional Availability (video); Infant Toddler Social Emotional Assessment/Strengths and Difficulties; Conflict Tactics Scale; Treatment Outcomes Profile; EQ-5D-5L. Other sources: Parent-completed service use (economic measure); Social work child protection data; NHS opioid substitution therapy prescription data. Practitioner reported attendance data. Interviews with fathers, mothers, practitioners (n=8), supervisors (n=2), service managers (n=7); focus groups with referrers (n=28); ‘expert event’ with stakeholders (n=39). Results: PuP was successfully delivered within non-NHS settings and acceptable and suitable for the study population. Referrals (n=44) resulted in 38 (86%) eligible fathers, of whom 25 (66%) fathers and 17 partners/mothers consented to participate. Most fathers reported no previous parenting support. Intervention engagement: 248 sessions delivered to 20 fathers and 14 mothers who started the intervention; 14 fathers (10 mothers) completed ≥ six sessions; six fathers (4 mothers) completed ≤ five sessions. Father and mother attendance rates were equal (mean: 71%). Median length of engagement: fathers 26 weeks, mothers 30 weeks. Research interview completion rates for fathers: 23 at baseline, 16 follow-up one, 13 follow-up two. Measures: well tolerated; suitability of some measures dependent on family circumstances; researcher administered questionnaires resulted in little missing data. Perceived benefits of PuP4Dads from parent, practitioner and manager perspectives: therapeutic focus on fathers, improved parental emotion regulation; understanding and responding to child’s needs; better multi-agency working; programme a good fit with practice ‘ethos’ and policy agenda. Learning highlighted importance of: service-wide adoption and implementation support; strategies to improve recruitment and retention of fathers; managing complex needs of both parents concurrently; understanding contextual factors affecting programme delivery and variables affecting intervention engagement and outcomes. Limitations: Lack of emotional availability and economic (service use) data. Conclusions: A larger evaluation of PuP4Dads is feasible. Future work: Demonstrating the effectiveness of PuP4Dads and the cost implications. Better understanding of how the intervention works, for whom, under what circumstances, and why
