Age norms for impulsiveness, venturesomeness and empathy in adults
Abstract
A total of 1320 Ss (559 males and 761 females) completed the I6 Impulsiveness Questionnaire. Reliabilities, scale intercorrelations, means and standard deviations as well as age means are given after some item changes from the original I5 Questionnaire. The resulting I7 Impulsiveness Questionnaire is reproduced in the Appendix, together with the scoring key. A further 589 Ss (383 males and 206 females) completed the new I7, together with the EPQ and intercorrelations of the seven factors obtained are given (i.e. Psychoticism, Extraversion, Neuroticism, Lie score, impulsiveness Venturesomeness and Empathy). A table of means and standard deviations for this second sample of Ss is also given for the sake of completeness.

A neuropsychological study of misophonia
2024, Journal of Behavior Therapy and Experimental PsychiatryMisophonia is a recently identified condition characterized by negative emotional responsivity to certain types of sounds. Although progress has been made in understanding of neuronal, psychophysiological, and psychopathological mechanisms, important gaps in research remain, particularly insight into cognitive function. Accordingly, we conducted the first neuropsychological examination of misophonia, including clinical, diagnostic, and functional correlates.
A misophonia group (n = 32) and a control group (n = 64) were screened for comorbidities using a formal semi-structured interview and completed a comprehensive neuropsychological battery and self-report measures of depression, anxiety, stress, impulsivity, and functional impairment.
The misophonia group significantly underperformed the control group on only 2 neuropsychological outcomes involving verbal memory retrieval. Subscales of the Misophonia Questionaaire (MQ) were inversely correlated only with measures of attention. The misophonia group reported significantly higher anxiety symptoms, behavioral impulsivity, and functional impairments, and had numerically higher rates of ADHD and OCD.
To facilitate comparability, in lieu of a formal diagnostic algorithm for misophonia, we used a commonly used empirical definition for group allocation that has been utilized in numerous previous studies.
Misophonia was associated with a reduction in performance on a minority of cognitive tasks and a modest increase in some psychological symptoms and comorbid conditions. Correlational data suggest that difficulties with attention regulation and impulsivity may play a role in misophonia, albeit attention functions were intact. Results should be interpreted with caution given the variability in diagnostic definitions, and more research is needed to understand cognitive functioning under ‘cold’ conditions in misophonia.
Rejection thresholds for sweetness reduction in a model drink predict dietary sugar intake
2023, Food Quality and PreferenceLinks between individual sweetness perception and sugar intake have been previously explored, with highly contrasting results. The current study aims to test individual-based rejection thresholds (RjTs) to ascending and descending sucrose concentrations in a model drink, and to evaluate potential links between these measures and sugar intake behaviour in real life. Sixty-three participants (final N = 43 [f = 29]; 20 ± 5 years) each undertook three sensory testing sessions and completed a 4-day weighed food records. Each individual was tested for their Sweet Liker status, detection thresholds to sucrose, RjTs to 5 descending and 5 ascending sucrose concentrations in an orange-flavoured drink, as well as sugar intake in daily diet and from sweetened beverages. The results demonstrate that RjTs can be estimated an individual level. With each participant completing 4 replications of the RjT task, data from over 88% of participants produced a reasonable individual-based psychometric function. Intriguingly, descending, but not ascending, RjTs were positively correlated with sweet liking (r = 0.43, p < 0.01), and acted as a significant predictor of both overall dietary sugar intakes (R2 = 0.10, F(4,38) = 2.23, p = 0.050) and sugar intakes from sweetened beverages (R2 = 0.21, F(4,38) = 3.73, p = 0.012). While sweet likers (SL) and dislikers (SD) had comparable ascending RjTs (acceptance for sugar addition), they differed substantially in terms of descending RjTs (p = 0.002; acceptance for sugar reduction), with SL rejecting samples having > 47% sugar reduction (47 g/L), whereas SD rejecting samples with > 68% reduction (28 g/L). Overall, these findings suggest that descending RjTs is a useful measure for detecting a sensory-diet relationship, and should be considered to better inform sugar reduction targets and facilitate policies on product reformulation.
Do drivers need spiritual fitness? The mediating effect of spiritual fitness on the relationship between personality traits and risky driving behaviours
2023, Transportation Research Part F: Traffic Psychology and BehaviourDrivers’ risky behaviours continue to be a major cause of traffic fatalities. Cultural changes, including fast-paced lifestyles, considerably contribute to speeding, fatigue, and texting while driving. Investigating the causes of these behaviours and resilience factors that can prevent or reduce negative outcomes is vital. The construct of spiritual fitness— defined as ‘the ability to adhere to beliefs, principles, or values needed to persevere and prevail in accomplishing a mission’—is an interesting proposition developed by the U.S. Army. Intervention programmes related to spiritual fitness are effective for vehicle operators' performance optimisation. Thus, this study introduces this phenomenon into research on civilian drivers. Specifically, the relationships between spiritual fitness, personality traits, and risky driving behaviours were examined. The study group comprised civilian drivers (N = 1037; Mage = 39.48 ± 13.32 years) who completed online self-reported questionnaire. Results showed that spiritual fitness was related to personality traits and risky driving behaviours. Additionally, spiritual fitness was a predictor of risky driving behaviours. Finally, spiritual fitness mediated the relationship between personality traits (impulsiveness, empathy, and conscientiousness) and risky behaviours. These findings confirm that spiritual fitness is a relevant resilience factor that merits further investigation on how it affects the on-road performance of civilian drivers. Study limitations and other possible research avenues are outlined.
Impulsivity dimensions and their associations with disinhibited and actual eating behaviour
2023, Eating BehaviorsPrevious research has suggested that there is an association between impulsivity, assessed via self-report measures and behaviourally, and disinhibited eating patterns, but it remains unclear which specific dimension of impulsivity is the most salient in this relationship. Furthermore, it remains uncertain whether any such associations would extend to actual eating behaviours and food consumption. Aims: The present study aimed to examine whether impulsivity, assessed both behaviourally and via self-report, is associated with self-reported disinhibited and actual eating behaviour in a controlled eating task.
70 women from a community sample (aged 21–35) completed the Disinhibition subscale of the Three Factor Eating Questionnaire (TFEQ), the Barratt Impulsiveness Scale (BIS-11), the Matching Familiar Figures Task (MFFT-20), and a behavioural food consumption task.
Bivariate correlational analyses revealed significant associations between self-report measure of impulsivity, the scores on the MFFT-20 (assessing reflection impulsivity), and self-report measure of disinhibited eating. All these measures were associated with overall food consumption in a taste task, with reflection impulsivity, that is poor ability to reflect on information before making a decision, having the strongest association with the amount of food consumed. Self-reported impulsivity was most strongly associated with disinhibited eating. Partial correlations controlling for BMI and age did not diminish any significant correlations within these relationships.
Significant associations between both trait and behavioural (reflection) impulsivity, and self-reported disinhibited eating and actual eating behaviour were demonstrated. The implications of these findings on uncontrolled eating patterns in real life are discussed.
Impulsivity and loot box engagement
2023, Telematics and InformaticsLoot boxes (randomised rewards in video games) possess structural similarities to traditional forms of gambling, with a well-documented and robust link between problem gambling symptomatology and loot box spending. In this research, we present two studies investigating the role of impulsivity (an established predictor for problem gambling behaviour) and reward/punishment sensitivity in predicting loot box spending. Across two samples, recruited from MTurk (n = 342) and Prolific Academic (n = 1142), Positive Urgency and Sensation Seeking (measured using the short UPPS-P) and BAS-Drive (measured using the BIS/BAS) were positively correlated with loot box spending. Combined, results indicate a positive reinforcement process is important in understanding loot box spending but provide evidence against a negative reinforcement mechanism (i.e., purchasing loot boxes to mitigate negative affect). Beyond problem gambling symptomatology, impulsivity may play a role in loot box purchasing. However, the impulsive factors implicated in loot box purchasing appear to differ in some ways from those implicated in problem gambling.
An exploration of multivariate symptom clusters of cannabis use disorder in young adults
2022, Addictive BehaviorsSince the release of the DSM-V, CUD has been understood as a unidimensional construct. However, continued research has identified separate symptom clusters relating to consumption, loss of control, and withdrawal within substance use disorder criteria that may pose separate risk factors and functional difficulties. The current study aims to examine how symptom clusters commonly manifest in young adults that use cannabis using a latent class analysis (LCA) and explore how these clusters are related to co-occurring psychological constructs.
1174 (aged 18–34) participants completed a battery of assessments on substance use and other psychological constructs. LCA was conducted on 17 symptoms corresponding with DSM-V CUD criteria. Multinomial regressions were used to examine class membership and commonly co-occurring psychopathology and psychological constructs.
LCA results identified a ‘No problems’ class, a ‘Moderate consumption’ class characterized by moderate probability of endorsing consumption items, a ‘Consumption with Moderate Loss of Control’ class, characterized by endorsing consumption and loss of control items but minimal endorsement of withdrawal items, a ‘Consumption with Moderate Withdrawal’ class characterized by moderate probability of endorsing all item types, and ‘High Consumption, Loss of Control, Withdrawal’ class characterized by high probability of endorsing all items. Multinomial regressions indicated some class differences in psychological constructs.
Symptom clusters differed in terms of CUD criteria, especially for those in our sample with moderate/severe problems. Findings suggest intervention efforts may benefit from treatment targeted at various presentations of CUD.
