Comparing the motivational underpinnings of sustainable consumption across contexts using a scenario-based approach.

A sample of tourists (N = 780) responded to a survey addressing purchasing intentions and consumption motives in relation to buying sustainable groceries at a local food market. These intentions and motives were contrasted for two consumption contexts: on vacation vs. at home. An initial analysis of the data indicated that self-reported purchasing intentions were weaker for a vacation scenario than for a home scenario. Further analyses suggested that motives associated with purchasing intentions were not universal between contexts. At home, normative motives (i.e., good conscience) were positively associated with intentions, whereas other motives failed to explain significant variance (i.e., value for money, calm and safe, avoid boredom, pleasure, and good impression). On vacation, associations with intentions followed a similar pattern, except for the finding that hedonic motives (i.e., pleasure) added explanatory variance. Despite the increased importance of hedonic motives on vacation compared to at home, normative motives showed the strongest association with purchasing intentions in both consumption contexts. The findings are discussed with reference to the literature on contextual discrepancies in environmental behavior, while noting possible implications for promoting sustainable consumption among tourists.

Expectation of others' cooperation, efficacy beliefs, and willingness to sacrifice personal interests for the environment.

This paper departs from the view that the social dilemma literature provides a useful framework to delineate possible barriers to the adoption of environmentally friendly lifestyles. One domain in which tensions between personal and collective interests might occur are travel decisions in the context of tourism, where it has been shown that even those people who are very committed to environmental practices at home tend to reduce respective commitments on vacation. Data from a cross-sectional survey N = 771 were analyzed to investigate if the expectation that other tourists travel environmentally friendly can in part explain individual travel decisions with environmental implications. Results showed that this expectation of others' cooperation added explanatory value in willingness to sacrifice (personal interests) for the environment. Further analyses indicated that the relationship between expectation of others' cooperation and willingness to sacrifice for the environment is sequentially mediated by collective efficacy and self-efficacy. We discuss implications for initiatives to gain a better understanding of travel decisions that can help limit environmentally harmful impacts.

Relationships Between Exposure to Different Gambling Advertising Types, Advertising Impact and Problem Gambling.

People with gambling problems report more exposure and impact from gambling advertising, although less is known regarding the role of specific advertising types. Data on gamblers (n = 5830, 48.5% women, mean age = 44.27) was collected from a general population cross-sectional survey in Norway (32.7% response rate). We examined if problem gambling was associated with perceived advertising impact (on gambling involvement, awareness, and knowledge) or exposure (via internet, TV, retail outlet, newspaper, and direct advertising). We also investigated if advertising exposure was associated with advertising impact. ANOVAs revealed that problem gambling was associated with increased perceived advertising impact on gambling involvement (ω2 = 0.09, p < .001) and awareness of gambling (ω2 = 0.04, p < .001). Reported exposure to direct advertising increased linearly with problem gambling level (ω2 = 0.04, p < .001), whereas we found small/no differences in exposure to other types of advertising. Multiple regressions revealed that among advertising types, internet advertising was the strongest predictor of perceived advertising impact on gambling involvement (ß = 0.1, p < .001). TV advertising was the strongest predictor of advertising impact on knowledge of gambling forms and operators (ß = 0.28, p < .001) and awareness of gambling (ß = .05, p < .05). Future studies should elucidate how different subtypes of internet advertising impact gambling involvement. Clinicians should assess clients' experiences with direct advertising and devise interventions for coping. Researchers should be aware that internet and direct advertising allow for more tailored content compared to other advertising types.

Lessons Learned From Applications of the Stage Model of Self-Regulated Behavioral Change: A Review.

Stage models are becoming increasingly popular in explaining change from current behavior to more environmentally friendly alternatives. We review empirical applications of a recently introduced model, the stage model of self-regulated behavioral change (SSBC). In the SSBC, change toward pro-environmental behavior takes place in four, qualitatively different stages (predecisional, preactional, actional, and postactional) which are each influenced by constructs taken from theories previously established to describe and predict pro-environmental behavior. We performed a systematic literature search to retrieve peer-reviewed SSBC-based studies. The review includes 10 studies published between 2013 and 2018, six of which employed a cross-sectional, three an interventional and one a correlational longitudinal design. The cross-sectional and longitudinal studies generally support the model, although there are some irregularities that warrant further investigation. The interventional studies found stage-tailored informational measures to be more effective than non-stage-tailored measures in promoting stage progression and behavioral change. Furthermore, we identified several challenges that researchers may face when applying the SSBC. These include whether and how to analyze multiple behavioral alternatives; how to address the challenge of measuring a comprehensive model while keeping questionnaire length manageable; selecting and defining the role of model constructs in a behavioral context while keeping results comparable; and establishing a validated and reliable tool to diagnose a person's stage of change. Based on these insights, we develop recommendations for researchers designing SSBC studies, in order to support a founded and efficient advancement of the theory which will then serve both researchers and practitioners aiming to promote pro-environmental behavior.

Using Card Sorting to Explore the Mental Representation of Energy Transition Pathways Among Laypeople.

Meeting international emission targets will require major changes in the energy system. This paper addresses the public perception of different pathways to energy transition, and their mental representation in particular. A study is reported that employed card sorting to explore how laypeople categorize possible pathway components with respect to their perceived similarity (Norwegian sample, n = 61; German sample, n = 71). Data sets that were obtained by this method were subjected to multidimensional scaling and cluster analysis. Results for both samples consistently indicate that people differentiate components located at the individual level (e.g., vegetarian food, avoid long flights, walking and cycling), components located at the societal level (e.g., taxes, regulations, urban planning), and components concerned with technological solutions (e.g., hydropower, wind farms, solar panels). These results give reason to assume that laypeople from Norway and Germany share a multifaceted understanding of energy transition, yet some differences between samples were present with regard to the substructure of the individual level category. Future research can build on the present results to explore the subjective meanings of these structures, possibly identifying barriers to public engagement with energy transition.

The effects of alcohol expectancy and intake on slot machine gambling behavior.

Background and aims Although alcohol intake and gambling often co-occur in related venues, there is conflicting evidence regarding the effects of alcohol expectancy and intake on gambling behavior. We therefore conducted an experimental investigation of the effects of alcohol expectancy and intake on slot machine gambling behavior. Methods Participants were 184 (females = 94) individuals [age range: 18-40 (mean = 21.9) years] randomized to four independent conditions differing in information/expectancy about beverage (told they received either alcohol or placebo) and beverage intake [actually ingesting low (target blood alcohol concentration [BAC] < 0.40 mg/L) vs. moderate (target BAC > 0.40 mg/L; ≈0.80 mg/L) amounts of alcohol]. All participants completed self-report questionnaires assessing demographic variables, subjective intoxication, alcohol effects (stimulant and sedative), and gambling factors (behavior and problems, evaluation, and beliefs). Participants also gambled on a simulated slot machine. Results A significant main effect of beverage intake on subjective intoxication and alcohol effects was detected as expected. No significant main or interaction effects were detected for number of gambling sessions, bet size and variation, remaining credits at termination, reaction time, and game evaluation. Conclusion Alcohol expectancy and intake do not affect gambling persistence, dissipation of funds, reaction time, or gambling enjoyment.

The Relationships between Mental Health Symptoms and Gambling Behavior in the Transition from Adolescence to Emerging Adulthood.

There is a paucity of longitudinal investigations of gambling behavior in the transition from adolescence to emerging adulthood. We conducted a longitudinal investigation of the associations and patterns of change between mental health symptoms and gambling behavior. A representative sample of Norwegians completed questionnaires containing demographic, mental health, and gambling measures at age 17 (N = 2055), and at ages 18 (N = 1334) and 19 (N = 1277). Using latent class analysis, three classes of gambling behavior were identified: consistent non-gambling (71.1%), consistent non-risk gambling (23.8%), and risky-and-problem gambling (5.1%). Being male, showing higher physical and verbal aggression and having more symptoms of depression were associated with greater odds of belonging to the risky-and-problem gambling class at age 17. Overall, the risky-and-problem gambling class had the highest physical and verbal aggression, anxiety, and depression at 19 years. Our findings elucidate the reciprocal relationship between mental health and gambling behavior in the transition from adolescence to emerging adulthood, and the importance of recognizing these factors in designing targeted interventions.

Prevalence and Predictors of Video Game Addiction: A Study Based on a National Representative Sample of Gamers.

Video gaming has become a popular leisure activity in many parts of the world, and an increasing number of empirical studies examine the small minority that appears to develop problems as a result of excessive gaming. This study investigated prevalence rates and predictors of video game addiction in a sample of gamers, randomly selected from the National Population Registry of Norway (N = 3389). Results showed there were 1.4 % addicted gamers, 7.3 % problem gamers, 3.9 % engaged gamers, and 87.4 % normal gamers. Gender (being male) and age group (being young) were positively associated with addicted-, problem-, and engaged gamers. Place of birth (Africa, Asia, South- and Middle America) were positively associated with addicted- and problem gamers. Video game addiction was negatively associated with conscientiousness and positively associated with neuroticism. Poor psychosomatic health was positively associated with problem- and engaged gaming. These factors provide insight into the field of video game addiction, and may help to provide guidance as to how individuals that are at risk of becoming addicted gamers can be identified.

Aggression Is Associated With Increased Anabolic-Androgenic Steroid Use Contemplation Among Adolescents.

We investigated the relationship between aggression and anabolic-androgenic steroid (AAS) use intent among adolescents. A nationally representative sample of Norwegian 18-year-olds (N = 1,334, females = 58.7%) took part in a survey in 2013 (response rate = 64.9%). Participants completed the physical and verbal subscales of the Short-Form Buss-Perry Aggression Questionnaire, the Intent to use AAS Scale, the Alcohol Use Disorders Identification Test-Consumption, and the Hospital Anxiety and Depression Scale. They also provided demographic information and answered questions about AAS use, gambling participation, as well as cigarette and snus use. Descriptive statistics and multinomial logistic regression were used to analyze the data. Lifetime and past year prevalence of AAS use was 0.1%. Between 0.4% and 1.7% of participants disclosed intent to use while between 1.1% and 2.5% expressed neutral intent to initiate AAS use. Compared to persons low on aggression, individuals high on aggression were more likely to report intent and curiosity towards initiating AAS use. Our findings indicate that aggression is a risk factor for AAS use contemplation among adolescents.

Problem gambling and the five-factor model of personality: a large population-based study.

BACKGROUND AND AIMS: Knowledge of the personality characteristics of individuals who develop gambling problems is important for designing targeted prevention efforts. Previous studies of the relationship between the five-factor model of personality and gambling problems were based on small samples not representative of the general population. We estimated differences in neuroticism, extroversion, intellect, agreeableness and conscientiousness between non-problem gamblers and individuals with low, moderate and severe gambling problems. DESIGN: Cross-sectional survey. SETTING: Norway. PARTICIPANTS: A total of 10 081 (51.5% female) individuals aged 16-74 years (mean age 46.5 years). MEASURES: The Problem Gambling Severity Index, The Mini-International Personality Item Pool and demographic variables. Differences between groups of gamblers were analysed by ordinary least-squares regression models separately for each personality trait adjusting for gender, age, cohabitation, level of education and work status. FINDINGS: Gamblers with low, moderate and severe levels of gambling problems differed significantly from non-problem gamblers in neuroticism (b = 0.16, 0.34 and 0.66, respectively, all P < 0.001) and conscientiousness (b = -0.13, -0.28 and -0.44, respectively, all P < 0.001). Moderate and severe problem gamblers differed from non-problem gamblers in agreeableness (b = -0.21, P < 0.001 and b = -0.20, P = 0.028, respectively). In addition, gambling problems were much more prevalent among men than women, and more prevalent among those who live alone, individuals without tertiary education and among those who are unemployed or on disability pension. CONCLUSIONS: A higher level of problem gambling severity appears to be associated with higher scores on neuroticism, and with lower scores on conscientiousness and agreeableness in the Mini-International Personality Item Pool.

A longitudinal study of factors explaining attitude change towards gambling among adolescents.

Background and aims No previous study has investigated changes in attitudes toward gambling from under legal gambling age to legal gambling age. The aim of the present study was therefore to investigate attitudinal changes during this transition and to identify predictors of corresponding attitude change. Methods In all 1239 adolescents from a national representative sample participated in two survey waves (Wave 1; 17.5 years; Wave 2; 18.5 years). Results From Wave 1 to Wave 2 the sample became more acceptant toward gambling. A regression analysis showed that when controlling for attitudes toward gambling at Wave 1 males developed more acceptant attitudes than females. Neuroticism was inversely related to development of acceptant attitudes toward gambling from Wave 1 to Wave 2, whereas approval of gambling by close others at Wave 1 was positively associated with development of more acceptant attitudes. Continuous or increased participation in gambling was related to development of more acceptant attitudes from Wave 1 to Wave 2. Conclusions Attitudes toward gambling became more acceptant when reaching legal gambling age. Male gender, approval of gambling by close others and gambling participation predicted development of positive attitudes toward gambling whereas neuroticism was inversely related to development of positive attitudes toward gambling over time.

Core and peripheral criteria of video game addiction in the game addiction scale for adolescents.

Assessment of video game addiction often involves measurement of peripheral criteria that indicate high engagement with games, and core criteria that indicate problematic use of games. A survey of the Norwegian population aged 16-74 years (N=10,081, response rate 43.6%) was carried out in 2013, which included the Gaming Addiction Scale for Adolescents (GAS). Confirmatory factor analysis showed that a two-factor structure, which separated peripheral criteria from core criteria, fitted the data better (CFI=0.963; RMSEA=0.058) compared to the original one-factor solution where all items are determined to load only on one factor (CFI=0.905, RMSEA=0.089). This was also found when we analyzed men aged ≤33 years, men aged >33 years, women aged ≤33 years, and women aged >33 years separately. This indicates that the GAS measures both engagement and problems related to video games. Multi-group measurement invariance testing showed that the factor structure was valid in all four groups (configural invariance) for the two-factor structure but not for the one-factor structure. A novel approach to categorization of problem gamers and addicted gamers where only the core criteria items are used (the CORE 4 approach) was compared to the approach where all items are included (the GAS 7 approach). The current results suggest that the CORE 4 approach might be more appropriate for classification of problem gamers and addicted gamers compared to the GAS 7 approach.

The impact of gambling advertising: Problem gamblers report stronger impacts on involvement, knowledge, and awareness than recreational gamblers.

Although there is a general lack of empirical evidence that advertising influences gambling participation, the regulation of gambling advertising is hotly debated among academic researchers, treatment specialists, lobby groups, regulators, and policymakers. This study contributes to the ongoing debate by investigating perceived impacts of gambling advertising in a sample of gamblers drawn from the general population in Norway (n = 6,034). Three dimensions of advertising impacts were identified, representing perceived impacts on (a) gambling-related attitudes, interest, and behavior ("involvement"); (b) knowledge about gambling options and providers ("knowledge"); and (c) the degree to which people are aware of gambling advertising ("awareness"). Overall, impacts were strongest for the knowledge dimension, and, for all 3 dimensions, the impact increased with level of advertising exposure. Those identified as problem gamblers in the sample (n = 57) reported advertising impacts concerning involvement more than recreational gamblers, and this finding was not attributable to differences in advertising exposure. Additionally, younger gamblers reported stronger impacts on involvement and knowledge but were less likely to agree that they were aware of gambling advertising than older gamblers. Male gamblers were more likely than female gamblers to report stronger impacts on both involvement and knowledge. These findings are discussed with regard to existing research on gambling advertising as well as their implications for future research and policy-making. (PsycINFO Database Record

Prevalence and Correlates of Problem Gambling in a Representative Sample of Norwegian 17-Year-Olds.

We report data collected in a representative sample of 17-year-old Norwegians to investigate prevalence rates of non-problem, risk, and problem gambling, as measured by the Problem Gambling Severity Index (PGSI). In addition, we explored the importance of demographic, personality, motivational, social, and health variables explaining variance in adolescent gambling. Prevalence rates of risk and problem gambling were low but similar to those found in previous studies outside of Norway using the PGSI in adolescent samples. With regard to the relative importance of the various covariates, we found that motivational variables (future gambling intentions, attitudes toward gambling, and gambling-related knowledge) distinguished best between those who did not gamble, non-problem gamblers, and risk and problem gamblers. Furthermore, social variables were important covariates of adolescent gambling; significant associations were found for family and friends' approval of gambling, parental monitoring, father's level of education, and having relatives or friends with a history of a gambling disorder. We discuss possible reasons for differences between the covariates with regard to their importance for explaining adolescent gambling and address implications for future research.
