“…Yet, the means do show that they are not prepared for challenging situations as many boys and girls do not make any coping plans. A recent study comparing Andalucian cannabis users and non-users also showed that cannabis users had much lower self-efficacy than non-users [ 10 ]. Our results show that the scores of girls and boys on self-efficacy and coping plans do not differ and thus do not need a more targeted approach.…”

“…Participants used schools’ computers or mobile phones to complete the online self-administered questionnaire which was previously validated by piloting [ 10 ] and lasted approximately 30 min of the class’s hour. An advantage of online surveys is that they do not allow the participant to advance without answering the first question.…”

“…The adoption of risk behaviours, including cannabis use [ 10 ], is determined by different factors. The Integrated Change Model acknowledges the existence of a variety of different factors (such as predisposing and motivational factors that influence a person’s intention and health behaviour such as cannabis use [ 11 ].…”

Objectives: This study assessed potential differences between girls and boys in the prevalence rates of cannabis use, sociodemographic factors, and beliefs about cannabis use.Methods: 1,896 Andalusian adolescents aged 14–18 participated in an online survey based on the I-Change model. The survey assessed their beliefs about cannabis use, including attitudes, social influences, self-efficacy, action planning, and intention to use. Multivariate analyses of variance were then conducted to examine potential gender differences in these beliefs, while controlling for last month’s cannabis use.Results: Significantly more boys used cannabis in the last month, had boyfriends/girlfriends, and had more pocket money compared to girls. Additionally, girls – in comparison to boys - were more convinced of the disadvantages of cannabis use, but were also more convinced of some of the advantages (such as freedom from boredom, and medicinal use), reported having less favorable social norms for cannabis use, had more female best friends using cannabis, and felt pressure to use cannabis from their female peers.Conclusion: These findings highlight the need for cannabis prevention programs to consider gender differences in beliefs about cannabis use. Programs should not only address general risk factors for cannabis use but also evaluate if their interventions effectively target beliefs that are particularly important for girls and boys.

“…The I-Change model integrates various theoretical models such as the Attitude Model-Social In uence-Self e cacy (or ASE-model) (22), the Theory of Planned Behavior by Ajzen (23,24), Bandura's Social Cognitive Theory (25), Transtheoretical Model of Change (26), Belief Model on Health and Goal Setting (27). Behavior change is generated through three stages: pre-motivational, motivational, and post-motivational, with the motivational stage serving as the foundation (21). Pre-motivational factors in uence behaviors and consist of predisposing factors (behavioral, psychological, biological, social, and cultural), awareness factors (knowledge, cues to action, and risk perception), and information factors (message, channels, and source), which.…”

“…Based on this scienti c evidence the school-based program Alerta Cannabis will be developed. It will use as theoretical model the Integrated Change Model (20), which has also turned out to be an explanatory model for the factors associated with the use of cannabis among Andalusian adolescents (21). This model integrates existing social cognitive models and can be used as a basis in computer-tailored information and communication technology.…”

Background The growing use of cannabis in adolescence is a public health problem that must be addressed through prevention. In Spain, the average age of initiation of cannabis use in the adolescent population is 14.8 years. At 14 years, the lifetime prevalence of cannabis use is 11.7%, which increases to 51.,5% at the age of 18; the prevalence of cannabis use in the population aged 14 to 18 years is 28.6%, a figure that must be tried to reduce, that is why this school prevention program is proposed: Alerta Cannabis. Methods The Alerta Cannabis research project consists of design, implementation, and evaluation. In the first phase, a computer-tailored eHealth program (Alerta Cannabis) is developed based on the I-Change Model, an integrated model based on three main behavioral change processes: awareness, motivation, and action. This program consists of four 30-minute sessions that will provide culturally adapted and personalized advice to motivate students not to use cannabis through text feedback, animations, and gamification techniques. This phase will also include usability testing. In the implementation phase, secondary school students from Western Andalusia, Spain (Seville, Cádiz, Huelva, and Córdoba) and Eastern Andalusia (Jaén, Málaga, and Granada) will be randomized to an experimental condition (EC) or a control condition (CC) for a cluster randomized clinical trial (CRCT). Each condition will have 35 classes within 8 schools. GI will receive the online intervention Alerta Cannabis. EC and CC will have to fill out a questionnaire at baseline, six months, and twelve months of follow-up. In the last phase, the effect of Alerta Cannabis is been evaluated. The primary outcomes are the lifetime prevalence of cannabis use and its use in the last 30 days and at 6 months. At 12 months of follow-up, the prevalence in the last 12 months will also be assessed. The secondary outcome is the intention to use cannabis. Discussion The study test the effect of the innovative program specifically aimed to reduce the use of cannabis in the adolescent population through eHealth in Spain. The findings aim to develop and implement evidence-based cannabis prevention interventions, which could support school prevention, for instance, the assistance of school nurses. If the program proves to be effective, it could be useful to prevent cannabis use on a national and international scale. Trial registration NCT05849636. Date of registration: March 16, 2023.
