Relationship of age to impulsivity and decision making: a baseline secondary analysis of a behavioral treatment study in stimulant use disorders

Selection, optimization and compensation strategies and their relationship with well-being and impulsivity in early, middle and late adulthood in a Polish sample

BACKGROUND

The model of selection, optimization, and compensation (SOC model) characterises the life management strategies that contribute to successful development. Although the SOC model is an important developmental theory, until now there has been no Polish version of a measurement tool for SOC strategies. The studies conducted so far have consistently indicated a relationship between the use of these strategies and well-being. In contrast, the relationship between SOC strategies and impulsivity has not yet been empirically examined, although there are theoretical premises to assume its existence. The aim of the study was to compare the use of SOC strategies in early, middle and late adulthood, and to investigate the relationship between the use of SOC strategies and well-being and impulsivity, using a newly developed Polish version of the SOC Questionnaire (SOC48-PL).

METHODS

The study applied a quantitative approach. The sample comprised 589 Poles from three age groups: early adulthood (n = 186, 20-35 years), middle adulthood (n = 165, 40-55 years) and late adulthood (n = 238, 60-85 years). In the study, in addition to the SOC48-PL questionnaire, the Short Depression-Happiness Scale (SDHS) and the Short UPPS-P Impulsive Behavior Scale (S UPPS-P) were used.

RESULTS

Developmental differences in the use of SOC strategies are rather slight, with considerable individual differences within age groups. The study revealed some indications of a 'developmental peak' of SOC strategies in middle adulthood. The use SOC strategies is positively related to well-being. In turn, the relationship between the use of SOC strategies and impulsivity is negative, especially for two dimensions of impulsivity: lack of premeditation and lack of perseverance.

CONCLUSIONS

The results only slightly confirm the assumed age-related differences in the use of SOC strategies and point to a large role of individual differences. The revealed positive relationships of SOC strategy use with well-being and negative with impulsivity are consistent with expectations. With the present study, the SOC48-PL questionnaire may find application in further studies on the SOC model involving the Polish population, as well as in the measurement of SOC strategies in psychological practice. Furthermore, the identified associations of SOC strategies with well-being and impulsivity can be taken as initial indications for the development of interventions based on teaching the use of SOC strategies. Cross-cultural comparisons, long-term longitudinal studies on changes in the use of SOC strategies over the life course, and combining quantitative and qualitative approaches in the analysis of the use of SOC strategies in practice are worth mentioning as directions for further research.

Discrete Roles for Impulsivity and Compulsivity in Gambling Disorder

Background and Objective: Complex associations between gambling disorder (GD) and impulsivity have been identified. However, little is known regarding how compulsivity associates with different impulsivity domains in GD. In this study, we examined associations between self-reported and behavioral measures of impulsivity-assessed through the Barratt Impulsiveness Scale (BIS-11) and the Experiential Discounting Task (EDT), respectively- and compulsivity-measured using the Padua Inventory and the Wisconsin Card Sorting Test (WCST), respectively-, in an adult sample with GD (N = 132, 94 men and 38 women, ages ranging from 18 to 69 years). GD severity was assessed using the South Oaks Gambling Screen. Methods: Structural Equation Modeling was used to examine relationships between impulsivity and compulsivity measures, age, and GD severity. Results: BIS-11 non-planning and BIS-11 total scores positively correlated with GD severity. The standardized coefficients for the SEM showed direct positive contributions of BIS-11 non-planning, Padua and EDT scores to GD severity. Only participants' ages directly contributed to WCST perseverative errors, and no direct or indirect effects were found with respect to GD severity. Conclusion: The findings suggest that specific aspects of impulsivity and compulsivity contribute to GD severity. Interventions specifically targeting domains that are most relevant to GD severity may improve treatment outcomes.

'Higher education' - substance use among Berlin college students

Berlin is internationally known for its intense nightlife associated with high rates of psychoactive substance use. Previous studies conducted in other cities indicated college students as a group at high risk for substance (mis-)use that was associated with individual psychological and cognitive impairments as well as lower academic performance. The aim of this study was to provide detailed data about the substance use patterns of Berlin college students. In addition, major protective and risk factors were analysed. An online questionnaire assessing sociodemographic data and various relevant aspects of both legal and illegal substance use such as consumption pattern and frequency as well as risk-taking behaviour was developed and distributed among colleges in Berlin. A sample of 9351 participants from 17 different colleges in Berlin completed the questionnaire. The study revealed high lifetime (69.3%), past year (45.9%) and past month (28.3%) prevalence of illicit substance use in the sample. Daily tobacco-smoking, a mental disorder diagnosis, a positive screening for problematic consumption (Cage-AID), bisexual orientation and living in open relationship were main factors positively associated with the prevalence and the extent of illicit substance use. Students in Berlin appear to show higher rates of illicit substance use than was previously reported for age-matched individuals in the general German population and college students in other cities. Thus, they are a relevant target group for early prevention and intervention concerning substance use and abuse.

Lifetime alcohol use and cognitive performance in older adults

Substance use is an important clinical issue in the older adult population. As older adults are susceptible to cognitive disorders, the intersection of the fields of substance use and cognitive neuroscience is an active area of research. Prior studies of alcohol use and cognitive performance are mixed, and inconsistencies may be due to under- or over-adjustment for confounders. This article adds to this literature by conducting a secondary analysis of self-reported lifetime history of alcohol use and cognitive performance in older adults (n = 133). It was hypothesized that current alcohol users would have poorer cognitive performance compared to never/minimal and former alcohol users. Older adult participants were classified into never/minimal alcohol users, former alcohol users, and current alcohol users. A neurocognitive battery included a global cognitive measure and individual measures of attention, memory, fluency, and executive function. A directed acyclic graph-based approach was used to select variables to be included in the multiple linear regression models. Though unadjusted analyses showed some significant associations between alcohol use and cognitive performance, all associations between alcohol use and cognitive performance were eliminated after adjusting for age, education, sex, race, and smoking pack years. Alcohol drink years were not significantly associated with cognitive performance among current and former alcohol users. These results suggest that lifetime alcohol use is not significantly associated with cognitive performance in older adults after adjustment for key confounders. Inconsistencies in prior studies may be due to uncontrolled confounding and/or unnecessary adjustment of mediators and/or colliders.

Substance use history in behavioral-variant frontotemporal dementia versus primary progressive aphasia

As older adults are prone to cognitive disorders, the interaction of the fields of substance use and misuse and cognitive neuroscience is an emerging area of research. Substance use has been reported in some subtypes of frontotemporal dementia, such as behavioral variant frontotemporal dementia. However, characterization of substance use in other subtypes of frontotemporal dementia, such as primary progressive aphasia, is unknown. The objective of this baseline analysis was to explore whether any measures of substance use history differed significantly among behavioral variant frontotemporal dementia (n = 842) and primary progressive aphasia (n = 526) in a large national dataset. The National Alzheimer's Coordinating Center's Uniform Data Set study is a national dataset that collects data on patients with various cognitive disorders and includes some questions on substance use. Each substance use variable was used as the outcome and the frontotemporal dementia subtype as the predictor. Total years smoked cigarettes, age when last smoked cigarettes, average number of packs/day smoked when participants smoked, and any recent, remote, or combined recent/remote history of alcohol abuse or drug abuse did not significantly differ between the behavioral variant frontotemporal dementia and primary progressive aphasia subtypes (all p-values > .001). A significantly greater percentage of participants smoked in the last 30 days in the behavioral variant frontotemporal dementia subtype (10.4%, n = 834) compared to the primary progressive aphasia subtype (3.3%, n = 517; p < .001). Clinical providers in both the dementia and substance use fields are encouraged to screen for and monitor substance use in all frontotemporal dementia subtypes.
