Indiana University-Purdue University Indianapolis (IUPUI) / Alcohol related problems and abuse continue to be serious problems in the U.S. today affecting nearly 17.6 million Americans. Understanding of the specific genes and related behaviors associated with alcohol use may provide substantial preventative measures for those who are at an increased risk. Genetically selected lines such as the high-alcohol preferring (HAP) and low-alcohol preferring (LAP) mice have been created to examine which endophenotypes co-segregate with alcohol preference. One behavioral trait that has been commonly associated with alcohol related problems is impulsivity. Impulsivity is the inability to withhold a response (motor impulsivity) or to act without forethought (cognitive impulsivity). The latter comprises much of the research and literature today using delay discounting models to tease out differences in subject’s wiliness to discount larger reinforcers for smaller immediate reinforcers. This study utilized relatively two newer paradigms associated with motor impulsivity in attempt to test differences in response disinhibition between two independent replicate HAP and LAP lines. It is hypothesized that the genes responsible for alcohol preference would be genetically correlated with motor impulsivity as HAP mice would display a greater degree of response disinhibition. Two independent replicates consisting of 48 mice (24 HAP II and 24 LAP II, representing the 37th generation; 24 HAP III and 24 LAP III, representing the 13th generation) were tested in two separate identical experiments. Each experiment was comprised of three phases. Phase I utilized a fixed interval (FI) 120s procedure for 30 days. After the 30 days of FI exposure mice were immediately moved to phase II for 10 days which implored a differential reinforcement of low rate procedure (DRL) at a time interval of 20s. Phase III used the same procedures as Phase II except the DRL was increased to 32s. As hypothesized, there was a moderate genetic correlation between alcohol preference and impulsivity as the HAP II mice displayed greater response disinhibition throughout all three phases compared to the LAP II mice. No differences were observed amongst the replicate III mice in any of the three phases. The findings from this study provide additional support that a genetic correlation between alcohol preference and impulsivity exists as seen in the delay discounting literature. Though this was observed in only one of the two replicates, interpretations must be taken at caution as the replicate III mice are still in the early stages of selection. It is possible at this stage in the selection process that increases in alcohol over successive generations are associated with selecting for taste until a threshold is met where selection shifts to pharmacologic drinking relevance. Until later generations of replicate III mice are studied where pharmacologic drinking occurs, conclusions from this study provide a moderate genetic correlation between alcohol preference and impulsivity.

Bakgrund: Fysisk aktivitet har visat sig ha en positiv effekt för både den psykiska och fysiska hälsan. Den kan minska psykiska problem som oro, stress och depression, samt fysiska åkommor som blodtryck, stroke och diabetes. Fysisk aktivitet är numera en allt mer vedertagen metod för att behandla fysiska och psykiska besvär. Individer med ADHD har vanligen problem med hyperaktivitet, impulsivitet, uppmärksamhet, sociala beteenden och kognitiva förmågor.Syfte: Att undersöka den vetenskapliga litteraturen för att få belägg för vilka effekter fysisk aktivitet kan ha för symptom hos individer med ADHD.Metod: I denna systematiska litteraturstudie återfanns via sökningar i databaserna PubMed, The Cochrane Library, Web of Science, Science Direct och PsycINFO artiklar som sedan granskades utifrån en bedömningsmall.Resultat: Fysisk aktivitet upplevdes ha en positiv effekt för hyperaktivitet och uppmärksamhetsproblem samt visade sig minska risken för sociala beteendeproblem hos individer diagnostiserade med ADHD. Vidare påvisades att oavsett regelbundenhet eller omfattning av fysisk aktivitet en positiv effekt för kognitiva förmågor hos individer diagnostiserade med ADHD.Konklusion: Den vetenskapliga litteraturen visar att fysisk aktivitet troligen har en positiv effekt för ett flertal symptom hos individer med ADHD. Dock krävs ytterligare forskning i ämnet. / Background: Physical activity has been shown to have a positive impact for both mental and physical health. It may reduce psychological problems such as anxiety, stress and depression, and physical issues like high blood pressure, stroke and diabetes. Physical activity is now an increasingly accepted method to treat physical and mental disorders. Individuals with ADHD usually have problems with hyperactivity, impulsivity, attention, social behavior and cognitive abilities.Aim: To investigate the scientific literature for evidence about the effect of physical activity on symptoms in individuals with ADHD.Method: In this systematic literature review articles where found through the databases PubMed, The Cochrane Library, Web of Science, Science Direct and PsycINFO witch was later surveyed based on an assessment template.Results: Physical activity was perceived to have a positive effect for hyperactivity and attention problems and appeared to reduce the risk of social behavior problems in individuals diagnosed with ADHD. Furthermore, it was shown that regardless of frequency or extent of physical activity a positive effect was shown on cognitive abilities in individuals diagnosed with ADHD.Conclusion: The scientific literature shows that physical activity is likely to have a positive effect for a variety of symptoms in individuals with ADHD. However, further research on the subject is required.

Road traffic crashes are a serious public health problem worldwide, and human factors are the most prominent factor of accidents, affecting mostly the young adults. Past studies found that both gender and personality traits such as impulsivity are associated with risky driving, however, the interaction of these predictors is rarely addressed in the literature. To bridge the gap, the present study explores how a specific facet of impulsivity interacts with our hypothesized moderator, gender identification, leads to drug driving using a moderator analysis. We recruited participants from 17 to 35 years old possessing a valid drivers' licence via Facebook advertising. They were invited to complete a questionnaire on their socio-demographic characteristics, cannabis consumption habits and impulsivity scores. A moderator analysis is conducted to disentangle the relationship between sensation seeking, gender and driving after cannabis consumption using SPSS Process. The proposed model contains sensation seeking as an exogenous variable directly associated with driving after cannabis use, and this relationship is moderated by gender identification. The current study provides evidence that sensation seeking and gender identification are not only associated with DACU but also interact to affect driving behaviour. Implications of the study are discussed. / Les accidents routiers constituent de graves problèmes de santé publique dans le monde et les facteurs humains sont connus pour être le principal facteur d'accidents, impliquant principalement les jeunes adultes. Des études antérieures ont démontré que le genre ainsi que des facteurs liés à la personnalité tels que l'impulsivité sont associés à la conduite après consommation récente de cannabis, cependant, l'interaction de ces prédicteurs est rarement abordée dans la littérature. Pour cette raison, cette étude vise à explorer le processus par lequel une facette spécifique de l'impulsivité interagit avec le genre ou le sexe pour modérer la probabilité de prendre le volant après avoir consommé du cannabis. Des participants de 17 à 35 ans possédant un permis de conduire valide ont été recrutés à partir de Facebook par le biais d’annonces payantes. Ils étaient invités à remplir un questionnaire portant sur leur caractéristique socio-démographique, leur habitude de consommation de cannabis, ainsi que sur les composantes de l'impulsivité. Une analyse de modération a été effectuée pour clarifier la relation entre la recherche de sensations, le genre et la conduite d’automobile à l'aide du SPSS PROCESS. Le modèle proposé inclut la recherche de sensations comme variable exogène directement associée à la conduite après la consommation du cannabis, et cette relation est modérée par le genre ressenti. Effectivement, le genre ressenti des participants semble être une variable modératrice de l’association entre la recherche de sensation et la prise de volant après avoir consommé du cannabis. Les implications de ces résultats seront discutées.

Syftet med aktuell studie var att undersöka om personlighetsegenskaper (från femfaktormodellen), BIS/BAS, kön och ålder kunde predicera studenters alkoholkonsumtion.  Alkoholkonsumtion är ett stort problem i dagens samhälle och bidrar till 3 miljoner dödsfall varje år globalt och leder till funktionshinder och dålig hälsa för miljontals människor. Studien använde sig av en korrelationell design och data samlades in med hjälp av ett självskattningsformulär. Urvalet bestod av 184 universitetsstudenter (77 % kvinnor) från tre olika program på Linnéuniversitetet i Kalmar och Växjö. Korrelationsanalysen visade signifikanta samband mellan alkoholkonsumtion och oberoende variabler där den starkaste effekten var ett medelstarkt positivt samband mellan BAS Fun Seeking och alkoholkonsumtion. Den efterföljande regressionsanalysen (MRA) visade att ålder, kön, BAS Fun Seeking och extraversion kunde predicera alkoholkonsumtion vilket stämde överens med studiens hypoteser och tidigare forskning. Resultatet från nuvarande studie ger en bättre förståelse för vilka variabler som kan predicera alkoholkonsumtion och utökar kunskap inom området vilket kan vara användbart för framtida hälsoprogram. / The aim of this study was to investigate whether personality factors (from the five-factor model), BIS/BAS, gender and age could predict students' alcohol consumption. Alcohol consumption is a major problem today, contributing to 3 million deaths each year globally and leading to disability and poor health for millions of people. The study used a correlational design and data were collected using a self-report questionnaire. The sample consisted of 184 university students (77% women) from three different programs at Linnaeus University in Kalmar and Växjö. The correlation analysis showed significant relationships between alcohol consumption and independent variables, with the strongest effect being a moderately strong positive relationship between BAS Fun Seeking and alcohol consumption. The multiple regression analysis (MRA) showed that age, gender, BAS Fun Seeking and extraversion could predict alcohol consumption, which was consistent with the study's hypotheses and previous research. The result from the current study provides a better understanding of which variables can predict alcohol consumption and expands knowledge in the field, which can be useful for future health programs.

Interoception, the signalling, processing, and perceptual representation of the visceral organs, together with trait impulsivity are in the present study examined using the Novel Controllability task (Mancinelli et al., 2021) as individual factors in coping behavior in response to stress. The coping process is conceptualized using the model of regulatory flexibility developed by Bonanno and Burton (2013). The results based on a sample of 39 healthy adults (M = 23,64 years, 22f/17m) do not support the hypothesis that the combined UPPS-P constructs are significantly related to interoception. For the coping process, the results suggest that: Negative Urgency is related to a negative initial appraisal of the stressor context leading to coping rigidity, by limiting the repertoire of strategies and the dynamic function of feedback; Positive Urgency is related to a larger dependency on emotions to guide decision making, motivating a “trial-and-error” coping approach; Sensation Seeking is related with an opposing style of emotion-focused coping where diminished threat perception and reduced sensitivity towards stimulus valence motivate a risk-taking approach, likely to pursue stimulation; Lack of Premeditation, the only facet of impulsivity convincingly related to interoception, is speculated to be associated with a dysregulation of interoceptive afferents facilitating a “here-and-now” attentional and coping focus. Despite lacking full support, the potential involvement of interoception as an internal stressor is discussed as a mediator in impulsive behavior, alongside general methodological issues with measuring interoception.

This study compares three groups of undergraduate college males in heterosexual dating relationships: those who are physically and psychologically abusive (n=39), those who are solely psychologically abusive (n=44), and those who are non-abusive (n=34). These three groups are compared along the following variables: self-reported history of experiencing family of origin violence; self-reported history of witnessing family of origin violence; level of self-reported impulsivity; level of self-reported satisfaction with life; level of self-reported alcohol use; level of self-reported relationship satisfaction; and amount of self-reported anger management skill. An analysis of variance (ANOVA) revealed significant main effects among the three groups of males along several of the variables examined (Wilks' Lambda F = 4.80, df = 10, 220, p <.001). Post hoc tests revealed significant differences among the three groups of males. This study revealed that these three groups differ significantly along their levels of alcohol use (F = 10.16, p <.001), their reported levels of relationship satisfaction (F = 4.23, p <.05), and their levels of anger management skills (F = 14.56, p<.001). This information can be helpful to clinicians and educators who are working with college populations. It would seem that psychoeducation might be useful for some of these men so that they might develop alternatives to violence, and may hopefully decrease the risk factors associated with the perpetration of relationship violence. Intervening early and effectively with these dating relationships can be a substantive step towards preventing the escalation and maintenance of violence in relationships. / Master of Science

The aim of this study was to create awareness of the emotional needs of children diagnosed with ADHD. In order to reach the aim of this study, an initial literature study was executed to describe ADHD and the emotional needs of children. Semi-structured interviews and two projective techniques were used to conduct the empirical study. Valuable data was also collected from the biographical questionnaires completed by the parents. Based on the data collected and analysed, findings were made which were verified by means of a second literature study. This was followed by conclusions which served as the basis for recommendations that were made in the form of guidelines to the parents, with the aim to make the parents aware of the emotional needs of their children diagnosed with ADHD. These guidelines will be made available to the parents at a seminar that will be held on acceptance of this research. / Social Work / M.Diac. (Play Therapy)
