For some adolescent gamers, playing online games may become problematic, impairing functioning in personal, family, and other life domains. Parental and family factors are known to influence the odds that adolescents may develop problematic gaming (PG), negative parenting and conflictual family dynamics increasing the risk, whereas positive parenting and developmentally supportive family dynamics protecting against PG. This suggests that a treatment for adolescent PG should not only address the gaming behaviors and personal characteristics of the youth, but also the parental and family domains. An established research-supported treatment meeting these requirements is multidimensional family therapy (MDFT), which we adapted for use as adolescent PG treatment. We report here on one adaptation, applying in-session gaming. In-session demonstration of the “problem behavior” is feasible and informative in PG. In the opening stage of therapy, we use in-session gaming to establish an alliance between the therapist and the youth. By inviting them to play games, the therapist demonstrates that they are taken seriously, thus boosting treatment motivation. Later in treatment, gaming is introduced in family sessions, offering useful opportunities to intervene in family members' perspectives and interactional patterns revealed in vivo as the youth plays the game. These sessions can trigger strong emotions and reactions from the parents and youth and give rise to maladaptive transactions between the family members, thus offering ways to facilitate new discussions and experiences of each other. The insights gained from the game demonstration sessions aid the therapeutic process, more so than mere discussion about gaming.  相似文献

Civic actions are behaviours intended to improve conditions for others or help shape a community's future. Such actions vary widely from voting to voluntary helping, from canvassing to community organizing, and attempts have been made to categorize the array of civic actions. However, the question of why young adults engage in some types of civic actions versus others is not well understood. Using data from 598 White, cisgender, heterosexual young adults in the United States, we examined the relations between individual civic efficacy, collective civic efficacy, and seven actions: writing social media posts, voting, buycotting, volunteering, participating in an organization, supporting political candidates, and protesting. We hypothesized that individual efficacy would be positively related to all seven actions, but collective efficacy would be more strongly related to collective or political actions, compared to the individual or civil ones. Logistic regression analyses showed that individual efficacy positively predicted engagement in all seven civic actions. Individual and collective efficacy had a complex curvilinear relation with buycotting and supporting political candidates. Implications for future research and applications aimed at promoting civic engagement amongst young adults are discussed.

A computational short cut suggested by Feldman and Klinger for the one-sided Fisher-Yates exact test is clarified and is extended to the calculation of probability values for certain two-sided tests when sample sizes are unequal.  相似文献

A discriminated Sidman avoidance procedure used by Forgione (1970) was replicated using a head-poke response instead of a leverpress as the avoidance operant. The resultant data were described in terms of the five dependent measures reported by Forgione. Head-poke avoidance was found to be more efficient than its leverpress counterpart and compared very favorably with the lever-disabling (or shock-timer-on) procedure used by Forgione to break up inefficient leverpress behavior patterns.  相似文献

Over 18,000 students at Michigan State University reported their attendance at 46 campus events. Student characteristics were analyzed in terms of student attendance patterns. The 46 events were grouped into 4 independent categories that were attended by students with different characteristics. Students who attended cultural events were mostly single upperclassmen majoring in liberal arts; musical events were attended mostly by music majors; those attending athletic events tended to be single male undergraduates from the more applied disciplines; and social events were attended mostly by undergraduate girls.  相似文献

97 parent-daughter pairs and 80 parent-son pairs were administered a value-orientation instrument when the children were in junior high school and again 2 years later. Girls became more concerned with what they could give of themselves in their eventual work. Girls' parents began to stress home-making qualities. Boys became less concerned with the more tangible rewards of work and more concerned with utilizing their capabilities. Boys' parents rated all the values more important than did their sons. Boys and their parents evidenced more disagreement regarding values than did girls and their parents. However, when focusing on the most important value, there is considerable agreement between children and parents. Parents have remained consistent in their value ratings over the 2 years while children have changed their ratings in the direction of the values their parents hold for them. The children of parents who have changed their value ratings were not different from children of parents who remained consistent in the ratings. Nor were children who changed their value ratings different from those whose values were stable.  相似文献
