Validation of the Facebook Addiction Questionnaire
No full textExisting self-report measures of Facebook addiction are limited by the robust application of addiction theory. This study validated a new theoretically derived measure of Facebook addiction. We hypothesized a single dimension construct of Facebook addiction based on Griffith's model would best fit the data. Competing alternative models included those based on DSM-5 substance-related and addictive disorder criteria. A cross-sectional sample of college students (18–25 years) with an active Facebook account (N = 431) completed the Facebook Intrusion Questionnaire (FIQ) and additional items measuring all of Griffiths' symptom components and the DSM-5 criteria for substance use, gambling, and Internet gaming; and validated measures of Internet addiction, personality, and mental health. A confirmatory factor analysis indicated a single-factor 14-item solution based on Griffith's model did not fit the data. A modified 10-item solution was the preferred measurement model due to brevity and stronger psychometric properties. This model demonstrated superior fit to alternative DSM-5-based models and the FIQ, while retaining theoretical consistency. The new 10-item measure, the Facebook Addiction Questionnaire (FAQ) demonstrated good reliability and construct validity. The 10-item FAQ is a reliable, valid, and brief measure of Facebook addiction that is theoretically and empirically superior to previous measures of Facebook addiction.No Full Tex
Reward Drive Moderates the Effect of Depression-Related Cognitive Mechanisms on Risk of Prescription Opioid Misuse Among Patients With Chronic Non-Cancer Pain
No full textDepression, a prognostic factor for prescription opioid misuse commonly occurs in people with chronic non-cancer pain (CNCP). However, the mechanisms linking depression and prescription opioid misuse remain unclear. This study examined the potential mediating role of pain catastrophizing in the association between depressive symptoms and prescription opioid misuse risk, and impulsivity traits as possible moderators of these relationships. Individuals (N = 198; 77% women) with CNCP using prescription opioids participated in a cross-sectional online survey with validated measures of depression, pain catastrophizing, rash impulsiveness, reward drive, anxiety, pain severity and prescription opioid misuse. Meditation analyses with percentile-based bootstrapping examined pathways to prescription opioid use, controlling for age, sex, pain severity, and anxiety symptoms. Partial moderated mediation of the indirect effect of depressive symptoms on prescription opioid misuse risk through pain catastrophizing by rash impulsiveness and reward drive were estimated. Pain catastrophizing mediated depressive symptoms and prescription opioid misuse risk. Indirect effects were stronger when moderate to high levels of reward drive were included in the model. Findings suggest the risk of prescription opioid misuse in those experiencing depressive symptoms and pain catastrophizing is particularly higher for those higher in reward drive. Treatments targeting these mechanisms may reduce opioid misuse risk. Perspective: This article identifies reward drive as a potentially important factor increasing the effects of depression-related cognitive mechanisms on risk of prescription opioid misuse in those with CNCP. These findings could assist in personalizing clinical CNCP management to reduce the risks associated with opioid misuse.Full Tex
Development of an individualized procedure to induce reward-related impulsivity and evaluating its impact on drinking control
No full textHigh impulsivity predisposes young adults to engage in hazardous alcohol use. Experimental research has shown that reward-related impulsivity is causally-related to heavier drinking. Correlational studies suggest that positive alcohol outcome expectancies mediate this effect, but causation has yet to be established. This study sought to clarify this relationship by: 1) developing a new, individualized procedure for inducing reward-related impulsivity with high generalizability; 2) experimentally manipulating positive alcohol expectancies to determine its mechanistic role in reward-related impulsivity risk for drinking. Eighty-seven young adults (67% female; Mage = 19.19, SD = 2.01) received either a covert manipulation to reduce positive alcohol expectancies (n = 43) or control (n = 44) after being administered the Individualized Reward-Seeking Induction Schedule (IRIS). The primary outcome was self-reported confidence in the ability to refuse alcohol in cued situations (drinking refusal self-efficacy). Results showed that IRIS increased reward-related impulsivity (p <.001, drm = 0.48) and reduced drinking refusal self-efficacy (p =.029, η2P =.055, ωp2 =.043). Experimentally diminishing positive alcohol expectancies had a marginal effect on the reward-seeking induction when controlling for covariates (p =.057, η2P =.044). Findings provide preliminary validation of IRIS as a new methodology for investigating the causal role of reward-related impulsivity in alcohol-related cognition and youth drinking.No Full Tex
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Testing a psychosocial model of sexual communication and sexual risk-taking: A cross-sectional, online survey study of Australian University students
No full textObjective: Sexually transmitted infection rates are higher among young people relative to other age groups. Despite much investigation, there is not enough research about in-the-moment factors associated with risky sexual behaviour, such as relational and situational variables. The present study sought to test a comprehensive psychosocial model of sexual risk-taking that included a range of factors: individual (emotion dysregulation, impulsivity), relational (attachment, communication), societal (norms, gender), and situational (dating application use, alcohol use). Methods: 1244 young people aged 18 to 25 years (82.9 % women; 59.2 % single, 36.0 % in a monogamous relationship) participated in an online survey. The cross-sectional model was tested using Structural Equation Modelling. Results: Sexual communication mediated the relationship between attachment anxiety and sexual risk. However, contrary to predictions, greater sexual communication was related to higher risk. Post-hoc analysis showed that this unexpected relationship may be due to the way sexual risk was measured, as an alternative model specifying casual unprotected sex as the outcome showed no positive relationship between sexual communication and risk. Conclusion: Findings indicate that young people with anxious attachment are less confident communicating about sexual health. Measures of sexual risk focusing on specific risk activities in context yield different findings to those assessing general sexual behaviours. Findings support interventions focusing on addressing perceived sexual risk norms and the dating application context to reduce risk.Full Tex
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
