Different risk factors are associated with alcohol use versus problematic use in male Pakistani adolescents

Substance abuse is a significant problem in Pakistan (Hussain, 2017), yet, there are few studies of risk factors in this population, particularly in remote areas. Male adolescents (N = 243; M = 16.9 years, SD = 1.3 years) were recruited from schools in Gilgit-Baltistan, and completed questions on demographics, substance use, and psychosocial functioning. As a Muslim country, there are strict prohibitions against alcohol use, yet 44.9% of the sample reported lifetime alcohol use. The Alcohol Use Disorders Identification Test (Babor, Higgins-Biddle, Saunders, & Monteiro, 2001), was used to quantify level of risk associated with use, and 22.6% of the sample had scores indicating significant risk levels. Logistic regression analyses indicated that lifetime alcohol use was associated with internalising problems (e.g., depression, anxiety), while risky alcohol use was associated with externalising problems (e.g., aggressive and delinquent behaviour). Attention problems were related to both outcomes. Implications for prevention are discussed.     

Psychological distress and resilience as risk and protective factors of psychoactive substance use among Chinese nonengaged youth

Nonengaged youth (NEY) are those who have neither been working nor studying for a prolonged period of time. They are at risk of psychoactive substance use, but relevant studies are scarce. Based on a population‐based telephone survey and referrals, we anonymously interviewed 479 Hong Kong Chinese NEY aged 15–24 years. Of them, 14.8–23.7% reported moderate to severe depression, anxiety, and stress. Moreover, one fourth of the participants (24.8%; n = 119) had used psychoactive substances. Adjusted analyses showed that these three psychological distress variables were positively associated with, while resilience was negatively associated with, both ever‐use of psychoactive substances and intention to use such substances in the next 12 months. Loneliness was associated only with intention to use psychoactive substances. The mediating role of psychological distress was shown: Anxiety significantly mediated the association between resilience and ever‐use of psychoactive substances, whereas depression mediated that between resilience and behavioural intention. Resilience was not a significant moderator on the relationship between psychological distress and ever‐use of psychoactive substance use or behavioural intention to use those substances. The findings suggest that anti‐drug interventions should outreach NEY and should include mental health support as well as building up resilience, as NEY are prone to psychological distress that increases risk of substance use.     

Relational Consequences of Compulsive Internet Use: A Longitudinal Study Among Newlyweds

This article examines how compulsive Internet use and marital well‐being are related to each other. We suggest that they are negatively related and explore whether compulsive Internet use predicts marital well‐being or vice versa. The relation between compulsive Internet use and marital well‐being is tested in a two‐wave prospective study among 190 newlywed couples. The results suggest that (a) compulsive Internet use predicts marital well‐being, and not vice versa, (b) that this is a within‐ rather than a cross‐partner effect, and (c) that the frequency of Internet use may be positively related to marital well‐being. The results are discussed in terms of the mechanisms that underlie the link between compulsive Internet use and relationship quality.     

Hope as a Moderator of the Associations Between Common Risk Factors and Frequency of Substance Use Among Latino Adolescents

Ample research suggests that delinquency, depressive symptoms, and peer substance use are common risk factors associated with adolescent substance use. However, the factors that may help to buffer the deleterious effects of these risk factors on adolescent substance use, such as hope, have yet to be examined. The current study evaluated hope as a moderator of the associations between these common risk factors and frequency of substance use (alcohol, tobacco, and marijuana) in a sample of Latino high school students (M _age ?=?16.14 years, SD?=?1.30; 55 % female). Findings indicated that the influence of delinquency on frequency of tobacco and marijuana use depended on levels of hope, with delinquency only positively associated with frequency of use when levels of hope were low. Additionally, hope moderated the association between depressive symptoms and alcohol use, such that depressive symptoms were only positively associated with frequency of alcohol use when levels of hope were low. Results and their implications for intervention are reviewed.     

The Effects of Childhood ADHD Symptoms on Early-onset Substance Use: A Swedish Twin Study

Research has documented that children and adolescents with attention-deficit/hyperactivity disorder (ADHD) are at increased risk of substance use problems. Few studies, however, have focused on early-onset substance use. This study therefore investigated how the two symptom dimensions of ADHD (hyperactivity/impulsivity and inattention) are associated with early-onset substance use, the role of persistent ADHD for the association, and to what extent the association is influenced by genetic and environmental factors. Twins (1,480 pairs) in the Swedish Twin Study of Child and Adolescent Development were followed from childhood to adolescence. ADHD symptoms were measured at age 8–9 and age 13–14 via parent-report, whereas substance use was assessed at age 13–14 via self-report. Results revealed that hyperactive/impulsive symptoms predicted early-onset “sometimes” tobacco use (adjusted odds ratios, 1.12, for one symptom count), controlling for inattentive symptoms and conduct problem behaviors. There is no independent effect of inattentive symptoms on early-onset substance use. Children with persistent hyperactivity/impulsivity (defined as scoring above the 75th percentile at both time points) had a pronounced risk of both early-onset tobacco and alcohol use (adjusted odds ratios from 1.86 to 3.35, compared to the reference group). The associations between hyperactivity/impulsivity and early-onset substance use were primarily influenced by genetic factors. Our results indicated that hyperactivity/impulsivity, but not inattention, is an important early predictor for early-onset substance use, and a shared genetic susceptibility is suggested to explain this association.     

Mood specific media use and emotion regulation: Patterns and individual differences

The present study examines moods in which individuals are most likely to utilize various forms of entertainment media and the emotion regulation tendencies that are associated with such preferences. Results of a questionnaire study (n = 229) show that mood specific media use may be captured by three factors: turning to media in a positive mood, in a negative mood or in a bored mood. Findings also show that various forms of difficulty regulating emotion (e.g., feeling out of control when upset) predict media use in negative or bored moods only. More specific analyses show that music use in negative moods is predicted by both positive indices (e.g., reflection tendencies) and negative indices of emotion regulation (e.g., rumination tendencies), while television use in negative moods is only predicted by negative indices of emotion regulation. Results are discussed in light of the psychological needs that selective media use may serve.     

A Note on the Definition of “Dual Use”

While there has been much interest in this topic, no generally accepted definition of dual use has been forthcoming. As a contribution to this issue, it is maintained that three related kinds of things comprise the category of dual use: research, technologies and artefacts. In regard to all three kinds, difficulties are identified in making clear distinctions between those that are and are not dual use. It is suggested that our classification should take account of actual capacities and willingness to make use of these objects for ‘bad ends’ and not the mere possibility that this could be done, and here three ‘contextual factors’ are identified. A (provisional) definition is proposed that takes account of threats and risks.     

Religiosity and Exposure to Users in Explaining Illicit Drug Use among Emerging Adults

Religiosity is a protective factor against illicit drug use, but further investigation is needed to delineate which components of religiosity are protective against use. A racially diverse sample (N = 962) was surveyed about religiosity, exposure to users, and recent use of marijuana, powder cocaine, ecstasy, and nonmedical use of opioids and amphetamine. Results suggest that identifying as Agnostic increased odds of use for each of the five drugs; however, this effect disappeared when controlling for religious importance and attendance. High levels of religious attendance were protective against recent use of marijuana and cocaine, but protective effects diminished when controlling for exposure to users, which was a robust predictor of use of every drug. Religion is a protective mechanism against drug use, but this effect may diminish in light of exposure to users. Alternative preventative methods need to be directed toward individuals who are not religious or are highly exposed to users.     

Workers' Compensation and Respondeat Superior Liability Legal Cases Involving Salespersons' Misuse of Alcohol

Legal cases where salespersons' misuse of alcohol resulted in either workers' compensation or respondeat superior liability cases are reviewed. Three main areas emerged which may require corporate attention: (1) salesperson travel including use of a home office, (2) condoning of alcohol use by corporations, and (3) the use of a company car. Corporation policy issues are discussed, as well as appropriate training suggested at the corporate and collegiate levels.     

Coping,psychological adjustment,and complementary and alternative medicine use in persons living with hiv and aids

Abstract

Many HIV-positive individuals dissatisfied with allopathic approaches to disease management have turned to complementary and alternative medicines (CAM). Although people use CAM for a variety of reasons (e.g., symptom management, holistic approach towards healthcare, improved immunity), the psychological benefits that these treatments may have are still not fully understood. The present study was designed to further previous research that demonstrated relationships between CAM use, stress appraisals, and coping behaviors. HIV-positive individuals (N= 127) completed measures assessing stress appraisals, coping, psychological adjustment, satisfaction with life, and immune functioning. After controlling for ethnicity and sexual orientation, stress appraisals and coping behaviors were found to be related to CAM use. Further, curvilinear relationships between CAM use and adjustment emerged, suggesting that some CAM use may be adaptive. Self-reported immune measures were unrelated to CAM use. In all, it appears that CAM use may be a complex form of coping that assists individuals in adjusting to a life-threatening illness. The implications of these findings with respect to adherence to highly active antiretroviral therapies (HAART) are also discussed.     

Marijuana Use Among Daily Tobacco Smokers: Relationship to Anxiety-Related Factors

The present investigation evaluated the incremental validity of regular marijuana use and frequency of such use in relation to anxiety and depressive symptoms and perceived health among young adult tobacco smokers (n = 202). Approximately 72% of the sample were current marijuana smokers, using this drug on an average of 7.6 (SD = 9.2) times per week. As expected, after controlling for theoretically-relevant smoking (cigarettes per day), alcohol use, and affect factors (i.e., negative affectivity and anxiety sensitivity), marijuana use predicted anxiety symptoms and perceived general health, whereas frequency of marijuana use predicted only anxiety symptoms. These results are discussed in relation to better understanding the role of regular marijuana use in terms of anxiety-relevant emotional vulnerability and beliefs about physical health among regular smokers.     

Usage des technologies numériques et modèles de la perméabilité des frontières entre la vie personnelle et la vie professionnelle

This study examines the determinants of porous borders personal and professional borders related to the use of information and communication technology (ICT). A mixed methodology that combines both a qualitative approach based on an exploratory interviews and a quantitative phase based on an online survey was followed to collect the data. The main findings of this study are: first, the permeability of personal (average score: 3.56) and professional (average score: 3.67) boundaries is experienced by most individuals. Second, the permeability is accelerated by the ICT use (70.9 % of respondents use the Internet at home for business purposes, 63.5 % use it at work for personal needs). Third, individuals manage differently this permeability by developing strategies based on their ICT use. These strategies go beyond the continuum “segmentation-integration”. There are four models: segmentation, spillover, integration and hybridization.     

Trust me if you can: The effect of driver username on passengers' intention to use ride-sharing service

Building trust and enhancing consumers' participation are critical for the growth of peer-to-peer sharing economy. This research explores the effect of driver username on passengers' intention to use ride-sharing service and its underlying psychological mechanisms. The results indicate that driver username has a significant impact on passengers' intention to use ride-sharing service, as a driver with a real name elicits greater intention to use ride-sharing service than a driver with a screen name (studies 1, 2, 3a, 3b, and 3c). In addition, the effect of driver username on passengers' intention to use ride-sharing service is serially mediated by social presence and trust (study 2). Importantly, the effect of driver username on passengers' intention to use ride-sharing service is moderated by driver reputation (studies 3a, 3b, and 3c). A high (vs. low) reputation facilitates the impact of driver username on passengers' usage intention. Based upon these findings, theoretical and practical implications are discussed.     

Operant conditioning of the EEG in two patients with epilepsy: Methodologic and clinical considerations

Methodologic and clinical considerations are discussed in sensorimotor rhythm (SMR) biofeedback research on two dissimilar but severe epileptic males. The first case, an akinetic epileptic who prior to feedback training experienced 80–100 clinical seizures every 10 hours, showed considerable seizure reduction after 6 months of SMR and epileptiform training. A number of methodologic and instrumentation advances were pioneered with the akinetic patient: (1) development of and ultra-sharp band-pass filter; (2) use of epileptiform inhibit and feed-back circuitry; (3) use of monetary rewards as additional incentive; (4) use of correlational analysis for evaluation of acquisition in the major dependent variables and; (5) use of noncontingent feedback and rein-forcement as control techniques. The second case, a psychomotor epileptic, also showed therapeutic benefit from SMR training. Clinical information regarding the effect of anticonvulsant medications on the course and therapeutic outcome of SMR training are described. In conjunction with operant conditioning of 12 Hz activity, corresponding changes for other EEG parameters are examined.     

Magpies can use local cues to retrieve their food caches

Much importance has been placed on the use of spatial cues by food-hoarding birds in the retrieval of their caches. In this study, we investigate whether food-hoarding birds can be trained to use local cues (“beacons”) in their cache retrieval. We test magpies (Pica pica) in an active hoarding-retrieval paradigm, where local cues are always reliable, while spatial cues are not. Our results show that the birds use the local cues to retrieve their caches, even when occasionally contradicting spatial information is available. The design of our study does not allow us to test rigorously whether the birds prefer using local over spatial cues, nor to investigate the process through which they learn to use local cues. We furthermore provide evidence that magpies develop landmark preferences, which improve their retrieval accuracy. Our findings support the hypothesis that birds are flexible in their use of memory information, using a combination of the most reliable or salient information to retrieve their caches.     

Changes in cannabis use in emerging adulthood: The influence of peer network,impulsivity, anxiety and depression

IntroductionCannabis is the most commonly used illicit drug with the highest prevalence reported among 15- to 24-year-olds. This specific period of emerging adulthood constitutes a critical age for substance use and for future consumption. Cannabis use patterns change during college or university and the post-college transition; users are at greater risk of adverse health outcomes (especially if they start or maintain a pattern of frequent use).ObjectivesThe overall aim of this study was to highlight psychological and relational factors that might be associated with changes (including cessation and fluctuation) in cannabis use during this specific period, separately for males and females.MethodsThe subjects were 682 first-year college students (69.94% of female), aged between 18 and 25 years (M = 18.59 years, SD = 1.56). Four groups were formed according to cannabis consumption: “non-users” (54.64%), “desisting users” (14.04%), “fluctuating users” (16.23%), and “persistent users” (15.07%). A self-report questionnaire was administered to evaluate prevalence, frequency and trajectory of use, number of peer cannabis users, alcohol use, impulsivity, anxiety (trait and social) and depression.ResultsFemales appear more sensitive to the romantic partner's consumption than males. For both sexes, having more friends who use cannabis appears to be a determinant. Depression and anxiety were not related to changes in cannabis use. Impulsivity is a significant factor for the maintenance of cannabis use in emerging adulthood, with higher lack of premeditation for males and higher sensation seeking for females among fluctuating and persistent users.ConclusionsResults are discussed in terms of maintenance of use and the spiral of consumption, including clinical implications for prevention and interventions.     

‘Language of the past’ – Exploring past tense disruption during autobiographical narration in neurodegenerative disorders

Compromised retrieval of autobiographical memory (ABM) is well established in neurodegenerative disorders. The recounting of autobiographical events is inextricably linked to linguistic knowledge, yet no study to date has investigated whether tense use during autobiographical narration is disrupted in dementia syndromes. This study investigated the incidence of correct past tense use during ABM narration in patients with Alzheimer's disease (AD, n = 10) and semantic dementia (SD, n = 10) in comparison with healthy older Controls (n = 10). Autobiographical narratives were analysed for episodic content (internal/external) and classified according to tense use (past/present). Across both patient groups, use of the past tense was significantly compromised relative to Controls, with increased levels of off‐target present tense verbs observed. Voxel‐based morphometry analyses based on structural MRI revealed differential associations between past tense use and regions of grey matter intensity in the brain. Bilateral temporal cortices were implicated in the SD group, whereas frontal, lateral, and medial temporal regions including the right hippocampus emerged in AD. This preliminary study provides the first demonstration of the disruption of specific linguistic constructs during autobiographical narration in AD and SD. Future studies are warranted to clarify at what point in the disease trajectory such deficits in tense use emerge, and whether these deficits are a product or contributing factor in memory disruption in these syndromes.     

Metaanalysis of Mood and Substance Use Disorders in Proximal Risk for Suicide Deaths

Evidence for proximal risk factors for suicide is based on case–control psychological autopsy studies, with these reports showing that mood and substance use disorders are the most prevalent mental disorders among suicide decedents worldwide and are associated with marked risk. However, moderators of risk and the degree of risk associated with (nonalcohol) drug use disorder are unknown. A comprehensive search was used to identify 35 case–control psychological autopsy studies published worldwide over a 30‐year period that were metaanalyzed using random effects models. Major depression, odds ratio (95% confidence interval) = 9.14 (5.53, 15.09), and drug use disorder, OR (95% CI) = 7.18 (3.22, 16.01), had large effect sizes, among other results. Risk estimates associated with major depression were greater in studies with a larger proportion of women and those conducted in Asia compared with other regions. There was no evidence of publication bias or that any one study had a disproportionate impact on findings. Risk for suicide associated with major depression appears to be moderated by sex and/or world region. Drug use disorder is a potent risk factor, illustrating the importance of assessing drug use in clinical risk assessment.     

Bringing up condom use and using condoms with new sexual partners: Intentional or habitual?

Abstract

A prospective study of 94 Dutch adults who have casual sexual partners examined whether two important aspects of safe sex, namely bringing up condom use (BCU) and actual condom use (ACU) are intentional or habitual. For each of these aspects, a model based on the Theory of Planned Behaviour (TPB: Ajzen, 1991) was pitted against a similar model that was extended with a path from past to later BCU and ACU, respectively. The results suggest that bringing up the issue of condom use was equally predicted by intentions and past BCU. However, among people with casual partners, using condoms - and more importantly not using condoms - was especially predicted by past ACU, suggesting a strong habitual component. These results are discussed in terms of their implications for safe sex education and the use of theories in safe sex promotion campaigns.
