Reinforcer pathology II: Reward magnitude,reward delay,and demand for alcohol collectively relate to college students' alcohol related problems

The reinforcer pathologies model of addiction posits that two characteristic patterns of operant behavior characterize addiction. Specifically, individuals suffering from addiction have elevated levels of behavioral economic demand for their substances of abuse and have an elevated tendency to devalue delayed rewards (reflected in high delay discounting rates). Prior research has demonstrated that these behavioral economic markers are significant predictors of many of college students' alcohol-related problems. Delay discounting, however, is a complex behavioral performance likely undergirded by multiple behavioral processes. Emerging analytical approaches have isolated the role of participants' sensitivity to changes in reinforcer magnitude and changes in reinforcer delay. The current study uses these analytic approaches to compare participants' discounting of money versus alcohol, and to build regression models that leverage these new insights to predict a wider range of college students' alcohol related problems. Using these techniques, we were able to 1) demonstrate that individuals differed in their sensitivity to magnitudes of alcohol versus money, but not sensitivity to delays to those commodities and 2) that we could use our behavioral economic measures to predict a range of students' alcohol related problems.     

Self-compassion induction enhances recovery from social stressors: Comparing adults with social anxiety disorder and healthy controls

Background and objectives: This study evaluates the process and consequence of inducing self-compassion during recovery from social performance stressors. Though interest in self-compassion as an intervention target is growing, extant findings suggest that initially cultivating self-compassion can be challenging for those with high self-criticism and anxiety, common features of social anxiety disorder (SAD).

Design: Quasi-experimental design.

Methods: The current study evaluates the feasibility, content, and outcomes of a brief written self-compassion induction administered after consecutive laboratory social stressors, among adults with SAD (n?=?21) relative to healthy controls (HC; n?=?35).

Results: Findings demonstrate the feasibility of employing a written self-compassion induction among adults with (and without) SAD, reveal group differences in written responses to the induction, and suggest that the SAD group benefitted more from the induction than the HC group, based on greater reductions in state anxiety and greater increases in self-compassion during stressor recovery. Greater use of negative affect words within written responses to the self-compassion induction, but not during general writing, predicted lower subsequent state anxiety across groups, by a medium effect size.

Conclusions: Collectively, the findings support the feasibility and utility of cultivating self-compassion among adults with SAD.     

Does spatial information impact immediate verbatim recall of verbal navigation instructions?

The present study addresses the issue of whether spatial information impacts immediate verbatim recall of verbal navigation instructions. Subjects heard messages instructing them to move within a two-dimensional depiction of a three-dimensional space consisting of four stacked grids displayed on a computer screen. They repeated the instructions orally and then followed them manually by clicking with a mouse on the grids. Two groups with identical instructions were compared; they differed only in whether the starting position was indicated before or after the instructions were given and repeated, with no differences in the manual movements to be made. Accuracy on both the oral repetition and manual movement responses was significantly higher when the starting position was indicated before the instructions. The results are consistent with the proposal that there is only a single amodal mental representation, rather than distinct verbal and nonverbal representations, of navigation instructions. The advantage for the before condition was found even for the oral repetition responses, implying that the creation of the amodal representation occurred immediately, while the instructions were being held in working memory. In practical terms, the findings imply that being able to form a mental representation of the movement path while being given verbal navigation instructions should substantially facilitate memory for the instructions and execution of them.     

Development and evaluation of a scale assessing therapist fidelity to guidelines for delivering therapist-assisted Internet-delivered cognitive behaviour therapy

Internet-delivered cognitive behaviour therapy (ICBT) is often accompanied by therapist emails, but there is limited research on the quality of this therapist-assistance. In this study, an ICBT Therapist Rating Scale (ICBT-TRS) was developed and evaluated to assess whether therapist emails showed fidelity to specific therapist behaviours. Using data from a previous ICBT trial for depression and anxiety, the ICBT-TRS was used to rate 706 emails sent by 39 therapists to 91 randomly selected patients. Emails were rated for adherence (absent/present) and quality (inadequate/competent) on the following behaviours: Builds Rapport, Seeks Feedback, Provides Symptom Feedback, Provides Psychoeducation, Facilitates Understanding, Praises Effort, Encourages Practice, Clarifies Administrative Procedures, and Communicates Effectively. Inter-rater reliability was high. Most behaviours were identified as present in 72–100% of emails, with the exception of Provides Symptom Feedback and Facilitating Understanding which were only present in 54 and 61% of emails. The majority of emails were rated as high quality (88–98% of messages). While not related to symptom improvement, ICBT-TRS ratings were higher when patients were more engaged in ICBT (e.g. log-ins) and among therapists who specialized in ICBT or had a background in Psychology. The ICBT-TRS has potential to facilitate ICBT research and clinical training.
