Measuring Gambling Outcome Expectancies in Adolescents: Testing the Psychometric Properties of a Modified Version of the Gambling Expectancy Questionnaire

A Cross-Sectional Survey to Measure Attitude, Self-Reported Practice, Levels, Typology, and Determinants of Lifetime Gambling Behaviors Among Undergraduate Students in Higher Training Institutions, Tanzania

Lifetime gambling activities and behaviors are considered as potentially addictive behaviors that may impact a student's performance. According to a survey conducted in Tanzanian's higher training institutions, for example, 37.2% of sports gamblers were students. This study employed an institutional-based cross-sectional survey in a quantitative research approach to study 374 randomly sampled undergraduate students in higher training institutions in Dodoma region, Tanzania from June to July 2023. Students reported their attitudes, practices, and drivers of gambling activities through interviewer-administered structured questionnaires adopted from previous studies. Results indicate that 374 of 583 potential participants were eligible and surveyed for the study with 100% response rate. Participants' mean age was 24 years ± 2.79 of which, few of them (34%) had age ranging between 25 and 42 years. Male participants accounted for 69.8% (n = 261). 59.1% of the study participants believed that gambling activities were okay to them of which 47.3% of them were lifetime gamblers; 19.2% moderate-risk lifetime gamblers and 2.5% low-risk lifetime gamblers respectively. Online sports betting (44.5%), coin pusher (29.4%), poll tables (8.0%), and slot machines (6.9%) were the most preferred types of gambling games among students. Age between 17 and 24 years; levels three and four classes, being male; living off-campus; drug abuse; mobile smartphone ownership; exposure to social media platforms and high attitude towards gambling activities were associated significantly with undergraduate students' gambling practices (p < 0.05). Large-scale institutional-based educational programs about the financial and academic ramifications of gambling among students during their studies may be able to moderate their gambling behaviors.

The Usefulness of a Revised Version of the Material Values Scale-Short Form in Italian Adolescents: Psychometric Evidence from Two Studies

Background: Materialism is an attitude that considers material goods to be central in life. Nowadays, adolescents appear to have a high level of materialism, which is related to risky behaviors. Nevertheless, there is a lack of measurement tools with adequate psychometric properties to assess materialism in this age group. For this reason, two studies were conducted to investigate the psychometric properties of the original and short Material Values Scale (MVS) in adolescents. Methods: In Study 1, participants were randomly split into two subsamples to compare psychometric properties of the original version of MVS with those of the short one. The first subsample consisted of 1054 adolescents (58% male; Mage = 16.34; SD = 1.15), and the second one of 1058 adolescents (57% male; Mage = 16.26; SD = 1.04). In Study 2, the psychometric properties of a revised version of the short MVS (without item 8) were investigated to confirm its adequacy with a new sample composed of 1896 adolescents (60% male; Mage = 16.40; SD = 2.76). Results: Results of Study 1 showed that the short version appeared to be a better measuring tool with respect to the long form to investigate materialism in adolescents. Nevertheless, problems with item 8 emerged. Results of Study 2 attested to the adequacy of the psychometric properties of the revised version of the short MVS (by excluding item 8) in this age group, in terms of dimensionality, reliability, and validity. Conclusions: Findings show that the revised short version of the MVS could be a valid and reliable tool for measuring the multidimensional construct of materialism in Italian adolescents.

A Structural Equation Model to Explain Gambling Problem Severity in Adolescents with an Integrated Perspective

To be effective in the prevention of adolescent problem gambling, it is fundamental to enhance knowledge about the antecedents of gambling problem severity and the mechanisms through which these dimensions are related to problematic gambling behavior. This study aimed at testing how selected cognitive (correct knowledge of gambling and gambling-related cognitive distortions) and affective (positive economic perception of gambling and expectation and enjoyment and arousal towards gambling) variables are related to gambling frequency and gambling problem severity. Problem gambling was conceptualized as Gambling Disorder symptoms according to the last edition of the DSM. Participants were 447 Italian high school students (68% males, mean age = 16.8, SD = 0.84). Structural Equation Models (SEMs) conducted with adolescent gamblers attested two indirect effects from knowledge to problem gambling: One through gambling-related cognitive distortions and one through gambling frequency. Overall, results confirmed that adolescent problem gambling is a complex phenomenon explained by multiple and different factors. Practical implications for preventive efforts are discussed.

How can we measure gambling craving among adolescent gamblers? Psychometric properties of the Gambling Craving Scale

BACKGROUND

Craving plays an important role in behavioural addictions such as Gambling Disorder (GD). However, it has only been included as a diagnostic criterion for substance addiction. Moreover, research on craving has focused mainly on adults, leaving out adolescents who can also be heavily involved in gambling behaviour. The purpose of this study was to investigate the psychometric properties of the most widely used craving assessment scale, the Gambling Craving Scale (GACS), in adolescent gamblers.

METHOD

For the current study, 1246 adolescent gamblers attending secondary school were recruited to complete a self-report questionnaire online. The psychometric properties of the GACS were examined: Confirmatory factor analysis was conducted; reliability was examined using the internal consistency method; in terms of validity, the relationship between the GACS total and subscale scores with some risk factors for problem gambling, gambling frequency and gambling problem severity was analyzed.

RESULTS

The factor analysis supported the three-factor structure, and good internal consistency was found for the GACS total scale and its three subscales. As regards validity, the GACS subscales resulted to be significantly and positively associated with economic perception of gambling and outcome expectancy, gambling-related cognitive distortions, gambling frequency, and problem gambling.

LIMITATIONS

The findings of this study were based on self-report data and only criterion validity was analyzed.

CONCLUSIONS

The GACS is a valid and rapid self-report measure of gambling craving in adolescent gamblers. In terms of prevention, the multidimensionality of the GACS is important for interventions. Clinical samples of adolescents are needed to confirm the validity of the scale.

Optimizing large-scale gambling prevention with adolescents through the development and evaluation of a training course for health professionals: The case of PRIZE

In the field of adolescent gambling prevention, there is a lack of intervention studies reporting and assessing training courses for the intervention providers. The present work fills this gap by realizing a dissemination study inside the PRIZE program aimed at modifying a set of cognitive protective factors and affective risk factors. The purpose of this work was twofold: To develop and evaluate a training course with the intervention providers (Study 1), and to assess the short- and long-term effects of the intervention itself (Study 2). The training course was delivered to 44 health professionals (32 females, Mage = 39.34 years). Results showed a significant increase of correct knowledge about gambling and a significant reduction of their susceptibility to probabilistic reasoning biases. Participants also actually learnt the main competencies to conduct the educational activities, they were satisfied for the training course received, and they felt high levels of self-efficacy. The intervention was implemented with 1894 high school students (61% males; Mage = 15.68 years). In the short term, we found a significant increase of adolescents' correct gambling knowledge, random events knowledge, and probabilistic reasoning ability, and a significant decrease of superstitious thinking, monetary positive outcome expectation, and gambling-related erroneous thoughts and fallacious behavioral choices. In the long-term, a significant decrease of gambling frequency, gambling versatility, and gambling problem severity was obtained. Overall, this work highlights the importance to train prevention program providers in order to optimize the effectiveness of large-scale gambling intervention programs towards adolescents.
