Composition of social networks to build recovery capital differ across early and stable stages of recovery,
Addiction Research & Theory – Roxburgh, A. D., Best, D. , Lubman D. I., & Manning, V. (2023)

The study provides evidence that the elements (e.g. diversity and number of supports) of a social network that facilitate recovery capital change as individuals progress through recovery stages, and highlights the importance of peer support in early recovery.

Negative urgency is related to impaired response inhibition during threatening conditions
Acta Psychologica, 228, [103648] – Roxburgh, A. D., White, D. J., & Cornwell, B. R. (2022).

The findings suggest the relationship between negative urgency and inhibition is facilitated by threatening conditions and that high sensation seekers experience threatening stimuli differently.

Anxious arousal alters prefrontal cortical control of stopping.

The findings support theoretical claims that beta oscillations function to maintain the current sensorimotor state, and that the lack of differential beta-band activity in prefrontal cortices underlies anxiety-related deficits in inhibitory control. We specifically argue that altered right IFG functioning might directly link impaired cognitive control to heightened stimulus-driven responding in anxiety states.

Threat-induced anxiety weakens inhibitory control
Biological Psychology, 144, 99-102. – Roxburgh, A. D., Hughes, M. E., & Cornwell, B. R. (2019).

This finding supports the claim of impaired inhibitory control in anxiety. Threat of unpredictable shocks reliably modulates anxious arousal. Anxious arousal negatively affects stopping efficiency on a stop-signal task. Slower stop signal reaction time implicates weakened inhibitory control in anxiety.

Proof-of-concept trial of Goal Management Training+ to improve executive functions and treatment outcomes in methamphetamine use disorder.

Deficits in executive function are common in methamphetamine use disorder (MUD), likely contributing to difficulties in sustained treatment success. Cognitive remediation interventions are designed to treat such deficits but have not been adapted to the needs of people with MUD. This study presents a proof-of-concept trial to evaluate a new cognitive remediation program for MUD, Goal Management Training+ (GMT+).

The Good No

The Good NO is for anyone who finds it hard to say NO to the requests, demands and expectations of others.

This book invites the reader into the world of NO and on a journey of how and why saying NO is a good idea.

Private drug rehab providers in Victoria call for regulation to protect patients from ‘exploitation’, ABC (2017)
Private drug rehabilitation providers are growing increasingly frustrated at a lack of government action to regulate the trouble-plagued sector.
Victoria’s Health Complaints Commissioner has so far this year received 22 complaints about some of the clinics, including for “exploitative billing practices”.

“Any Tom, Dick or Harry” can set up a drug rehab clinic in Victoria, according to Toby Lawrence from Arrow Health. “I’ve heard a lot of horror stories, we’ve heard about clients being mixed up in a romantic sense with the people that are providing therapy,” Mr Lawrence said.
