Impatience—the failure to wait or tolerate delayed rewards (e.g. food, drug and monetary incentives)—is a common behavioural tendency in humans. However, when rigidly and rapidly expressed with limited regard for future, often negative consequences, impatient or impulsive actions underlie and confer susceptibility for such diverse brain disorders as drug addiction, attention-deficit hyperactivity disorder (ADHD) and major depressive disorder. Consequently, ‘waiting’ impulsivity has emerged as a candidate endophenotype to inform translational research on underlying neurobiological mechanisms and biomarker discovery for many of the so-called impulse-control disorders. Indeed, as reviewed in this article, this research enterprise has revealed a number of unexpected targets and mechanisms for intervention. However, in the context of drug addiction, impulsive decisions that maximize short-term gains (e.g. acute drug consumption) over longer-term punishment (e.g. unemployment, homelessness, personal harm) defines one aspect of impulsivity, which may or may not be related to rapid, unrestrained actions over shorter timescales. We discuss the relevance of this distinction in impulsivity subtypes for drug addiction with reference to translational research in humans and other animals. This article is part of the theme issue ‘Risk taking and impulsive behaviour: fundamental discoveries, theoretical perspectives and clinical implications’.

Zusammenfassung. Zielsetzung: Monitoringsysteme für die Behandlung von Substanzbezogenen Störungen (MfS) werden eingesetzt, um den Gesundheitszustand der Zielgruppe, Interventionen und deren Ergebnisse zu erfassen. Die Entwicklung der bestehenden Systeme, Möglichkeiten und Probleme werden untersucht. Methodik: Da MfS selten Gegenstand wissenschaftlicher Publikationen sind, wurden, ausgehend von zentralen Publikationen des European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), der Pompidou-Gruppe und der Weltgesundheitsorganisation (WHO) / United Nations Office on Drugs and Crime (UNODC) relevante Publikationen gesucht. Diese sind, zusammen mit der langjährigen Erfahrung in deutschen und europäischen MfS, Grundlage der Darstellung. Ergebnisse: Ähnliche Bedingungen und ein regelmäßiger Austausch haben zu Gemeinsamkeiten bei nationalen und internationalen MfS geführt. Zentrale Merkmale sind: eine Vielzahl beteiligter Akteure aus Versorgung, Finanzierung, Wissenschaft, Technik und Administration; Themenfelder: Verfügbarkeit und Zugang, Effektivität und Effizienz, Akzeptanz und Nutzung von Behandlung; Erhebungseinheiten: Klient, Therapeut, Einrichtung, Behandlung und Ergebnisse. Daten aus der Routineerhebung werden in meist anonymisierter Form regelmäßig zusammengeführt und berichtet. Zentrale Ziele sind dabei die Erkennung von Trends und Veränderungen, Abschätzung von Bedarf und Rückmeldung über die Effekte von Interventionen. Als kritisch erwiesen sich die Repräsentativität der Stichproben, nicht zu kontrollierende Einflussfaktoren und Probleme der Vergleichbarkeit zwischen Regionen, Teilgruppen und über die Zeit. Schlussfolgerungen: MfS sollten trotz methodischer Probleme und Einschränkungen weiter verwendet werden, da Informationen zu Behandlungsbedarf, Durchführung und Ergebnissen von Interventionen im Bereich der Suchthilfe zeitnah notwendig sind und alternative Datenquellen fehlen. Eine klarere Zielsetzung und bessere Konzeption, langfristige Perspektiven, Unabhängigkeit und Qualitätssicherung, eine kritische Interpretation der Ergebnisse und eine bessere Verknüpfung zwischen MfS, anderen Datenquellen und wissenschaftlicher Forschung könnten Wert und Bedeutung von MfS deutlich erhöhen.

Abstract. The Balloon-Analogue Risk Task (BART; Lejuez et al., 2002 ) is one of the most popular behavioral tasks suggested to assess risk-taking in the laboratory. Previous research has shown that the conventionally computed score is predictive, but neglects available information in the data. We suggest a number of alternative scores that are motivated by theories of risk-taking and that exploit more of the available data. These scores can be grouped around (1) risk-taking, (2) task performance, (3) impulsive decision making, and (4) reinforcement sequence modulation. Their theoretical rationale is detailed and their validity is tested within the nomological network of risk-taking, deviance, and scholastic achievement. Two multivariate studies were conducted with youths (n = 435) and with adolescents/young adults (n = 316). Additionally, we tested formal models suggested for the BART that decompose observed behavior into a set of meaningful parameters. A simulation study with parameter recovery was conducted, and the data from the two studies were reanalyzed using the models. Most scores were reliable and differentially predictive of criterion variables and may be used in basic research. However, task specificity and the generally moderate validity do not warrant use of the experimental paradigm for diagnostic purposes.

Abstract. The study reports results regarding the dimensionality and construct validity of a newly developed, objective, video-based personality test that assesses the willingness to take risks in traffic situations. On the basis of the theory of risk homeostasis developed by Wilde, different traffic situations with varying degrees of objective danger were filmed. During the test the respondents are asked to indicate at which point the action that is contingent on the described situation will become too dangerous to carry out. Latencies at the item level were recorded as a measure for the subjectively accepted degree of a person's willingness to take risks in the sense of the risk homeostasis theory by Wilde. In a study on 274 people with different educational levels and gender, the unidimensionality of the test as corresponding to the latency model by Scheiblechner was investigated. The results indicate that the Vienna Risk-Taking Test - Traffic assesses a unidimensional, latent personality trait that can be interpreted as subjectively accepted degree of risk (target risk value).

Abstract. Gender and personality traits influence risk proneness in the context of financial decisions. However, most studies on this topic have relied on either self-report data or on artificial measures of financial risk-taking behavior. Our study aimed to identify relevant trading behaviors and personal characteristics related to trading success. N = 108 Caucasians took part in a three-week stock market simulation paradigm, in which they traded shares of eight fictional companies that differed in issue price, volatility, and outcome. Participants also completed questionnaires measuring personality, risk-taking behavior, and life stress. Our model showed that being male and scoring high on self-directedness led to more risky financial behavior, which in turn positively predicted success in the stock market simulation. The total model explained 39% of the variance in trading success, indicating a role for other factors in influencing trading behavior. Future studies should try to enrich our model to get a more accurate impression of the associations between individual characteristics and financially successful behavior in context of stock trading.
