概括
兄弟ACT应用程序展示了优秀的可用性和可接受性,年轻的黑人男性有枪支伤害的风险. 这种文化定制的移动健康工具提供了重要的危机前和心理健康资源,解决了严重的护理差距.
科学领域:
- 数字健康和移动健康 (mHealth) 干预措施
- 公共卫生和伤害预防
- 心理健康技术和数字治疗学
背景情况:
- 年轻的黑人男性面临着不成比例的高枪支伤害和杀人率,加之是获得护理和服务的障碍.
- 现有的基于社区的干预措施往往侧重于暴力后的反应,并没有充分接触到这个脆弱的人群.
- BrotherlyACT应用程序被开发为由护士领导的,文化定制的移动健康解决方案,以提供危机前和心理健康资源.
研究的目的:
- 评估年轻的黑人男性 (15-24岁) 和mHealth专家之间的 BrotherlyACT应用程序的可用性,参与度和满意度.
- 评估应用程序是否适合在低资源,高暴力环境中部署,以减少枪支伤害和物质使用风险.
主要方法:
- 采用了融合混合方法方法,将8名mHealth专家的启发性评估 (HE) 和23名参与者的可用性测试 (UT) 结合起来.
- UT参与了15名年轻的黑人男性用户,4名内部测试人员和4名青年顾问委员会成员,利用系统可用性量表和主题分析.
- HE利用尼尔森严重性评级尺度来识别可用性问题,所有测试都通过REDCap和Zoom或亲自进行.
主要成果:
- BrotherlyACT应用程序获得了系统可用性评分79分 (A-减数),表明近乎卓越的可用性,并将其置于第85个百分点.
- 启发式评估只发现了轻微和化品可用性问题,中位数严重性得分为1,这表明对用户体验的影响最小.

Group Design
8.9K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Operant Conditioning Intervention

Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.

Behavior Modification

Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.
