概括
研究人员需要至少两次观察会,以可靠地测量患有自闭症的高或一般可能性的婴儿的护理人员谈话. 这确保了自闭症研究的稳定估计.
科学领域:
- 发展心理学 发展心理学
- 自闭症谱系障碍研究研究
- 语音语言病理学 语言病理学
背景情况:
- 准确测量护理人员与儿童之间的互动对于了解早期发育至关重要,特别是在患有自闭症谱系障碍 (ASD) 风险的婴儿中.
- 用于量化护理人员谈话的观测系统需要确保得分稳定性,以最大限度地减少测量误差.
研究的目的:
- 为指导研究人员设计观察测量系统,以照顾有或没有ASD高概率的婴儿的照顾者谈话.
- 确定所需的观察会话和编码器数量,以稳定估计护理人员的谈话.
主要方法:
- 差异分析 (ANOVA) 用于分割错误差异 (编码器,会话).
- 推导了通用性 (g) 系数,决策研究确定了g ≥0.80.0的必要会话/编码器.
- 护理人员的后续谈话是从两个观察会议中编码的,12名 ASD 可能性较高的婴儿和12名一般人口可能性较高的婴儿,在12-18个月和9个月后.
主要成果:
- 两个会议和一个编码器在两个时间点实现了足够的稳定性,为护理人员的后续谈话和对两个婴儿组的评论提供了足够的稳定性.
- 后续的指令没有达到足够的稳定性,一般人群的概率组或较高的概率组在以后的时间点.
结论:
- 研究人员应该收集至少两次观察会的数据,以获得护理人员谈话的稳定估计.

Autism Spectrum Disorder
59
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Modeling in Therapy
46
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
