Individual differences in interpersonal security predict suicidal ideation and problem gambling

Suicidality and problem gambling represent global health issues. Based on evidence from recent literature, the aim of the present study was to test a theoretical model, in which: (1) Emotional Intelligence and Self and Other Representations of adult attachment combine into a latent factor representing Interpersonal Security; (2) Interpersonal Security negatively predicts Problem Gambling and Suicidal Ideation, respectively; (3) Problem Gambling positively predicts Suicidal Ideation. We used Structural Equation Modelling to test the study hypotheses. The model showed good fit to the data. Factor loadings were high and statistically significant. We found that the hypothesis of Emotional Intelligence and Self and Other Representations combining into a common factor, Interpersonal Security, is empirically supported. The joint effect of Interpersonal Security and Problem Gambling explains about the 63% of variance of Suicidal ideation. The path from Interpersonal Security to Suicidal Ideation is significant and high, whilst the path from Problem Gambling to Suicidal Ideation is not significant. Interpersonal Security explains about 16% of the variance of Problem Gambling. These results outline an integrated model of Suicidal Ideation and Problem Gambling in the community from an interpersonal-psychological perspective, with important implications for researchers, mental health practitioners, and policymakers

Psychometric properties of the Italian versions of the Gambling Urge Scale (GUS) and the Gambling Refusal Self-Efficacy Questionnaire (GRSEQ)

Gambling urges and gambling refusal self-efficacy beliefs play a major role in the development and maintenance of problem gambling. This study aimed to translate the Gambling Urge Scale (GUS) and the Gambling Refusal Self-Efficacy Questionnaire (GRSEQ) from English to Italian (GUS-I, GRSEQ-I) and to test their factor structure, internal consistency, construct validity, concurrent validity, and gender differences in 513 individuals from the Italian community. Factor structure and construct validity were tested through Confirmatory Factor Analysis, internal consistency through Cronbach’s alpha, concurrent validity through correlations with gambling-related cognitions (GRCS-I), probable pathological gambling (SOGS-I), and gambling functioning (GFA-R-I). Results confirmed that the 6 items of the GUS-I load highly on one dimension of Gambling Urge, and each of the 26 items of the GRSEQ-I load highly on their relevant sub-dimension, among the following: situations/thoughts, drugs, positive emotions, negative emotions. Both scales are internally consistent and show concurrent validity with gambling-related cognitions, probable pathological gambling, and gambling functioning. Males score higher than females at the GUS-I; females score higher than males at the GRSEQ-I. The findings from the present study suggest that the GUS-I and the GRSEQ-I are internally consistent and valid scales for the assessment of gambling urges and gambling refusal self-efficacy in Italian individuals from the community, with significant repercussions in terms of assessment, prevention, and intervention

Profiling Online Poker Players: Are Executive Functions Correlated with Poker Ability and Problem Gambling?

Poker playing and responsible gambling both entail the use of the executive functions (EF), which are higher-level cognitive abilities. This study investigated if online poker players of different ability showed different performances in their EF and if so, which functions were the most discriminating for their playing ability. Furthermore, it assessed if the EF performance was correlated to the quality of gambling, according to self-reported questionnaires (PGSI, SOGS, GRCS). Three poker experts evaluated anonymized poker hand history files and, then, a trained professional administered an extensive neuropsychological test battery. Data analysis determined which variables of the tests correlated with poker ability and gambling quality scores. The highest correlations between EF test results and poker ability and between EF test results and gambling quality assessment showed that mostly different clusters of executive functions characterize the profile of the strong(er) poker player and those ones of the problem gamblers (PGSI and SOGS) and the one of the cognitions related to gambling (GRCS). Taking into consideration only the variables overlapping between PGSI and SOGS, we found some key predictive factors for a more risky and harmful online poker playing: a lower performance in the emotional intelligence competences (Emotional Quotient inventory Short) and, in particular, those grouped in the Intrapersonal scale (emotional self-awareness, assertiveness, self-regard, independence and self-actualization

Dopaminergic striatal innervation predicts interlimb transfer of a visuomotor skill

We investigated whether dopamine influences the rate of adaptation to a visuomotor distortion and the transfer of this learning from the right to the left limb in human subjects. We thus studied patients with Parkinson disease as a putative in vivo model of dopaminergic denervation. Despite normal adaptation rates, patients showed a reduced transfer compared with age-matched healthy controls. The magnitude of the transfer, but not of the adaptation rate, was positively predicted by the values of dopamine-transporter binding of the right caudate and putamen. We conclude that striatal dopaminergic activity plays an important role in the transfer of visuomotor skills
