Methods: Our data consist of focus group interviews from Finland and Norway with teenagers aged 14–17 years (n?=?8 groups, n?=?44 participants) and parents (n?=?8 groups, n?=?38). Three pictures portraying different drinking situations were presented to the participants, who were asked to describe (1) what kind of situation the picture depicts, (2) whether the way of drinking in the picture was acceptable or not and (3) whether they identified with the situation or not.
Findings: Our analysis showed that teenagers and parents defined the situations similarly and applied rather similar criteria when assessing the appropriateness of drinking. The most important criteria related to the amount and the way of drinking, and whether or not children were present in the situation. Regarding the identification with the situations, teenagers seemed to have somewhat stricter attitudes towards intoxication than adults, which can be perceived as a sign of an ongoing trend of decreasing youth drinking.
Conclusions: Overall, our analysis suggests that the alcohol worlds of parents and teenagers resembled each other, supporting the notion that the generational gap between parents and teenagers is diminishing. 相似文献
Design and methods: Inductive content analysis was used to analyze the experiences of 31 Greek addiction professionals who participated in focus groups.
Findings: Professionals adopted various interventions which included (a) respond to parents quest for help, (b) involvement of the distant parent in treatment, (c) boundary setting, (d) facilitation of parent-child communication, and (e) support of parental changes. These interventions were perceived as necessary, both for motivating and sustaining the client’s change, and for alleviating the parents’ chronic grief and distress over their child’s addiction.
Conclusion: Overall, addiction professionals perceived low intensity interventions, information giving, and non- judgmental informal interactions as catalysts for the parents involvement in addiction treatment. 相似文献
