Treatment was provided to three 7-year-old participants with DLD in the context of multiple baseline designs across behaviors and participants. Phonological schemas included vowel change, final alveolar, and dual change irregular verbs. Treatment was provided using established therapeutic approaches, including narrative generation, sentence imitation, and naturalistic play activities. Acquisition of treated and untreated targets was assessed at the beginning of sessions, and use of verbs in naturalistic contexts was observed throughout treatment sessions.
Positive acquisition effects were noted for two of three participants. Generalization to untreated items occurred within and across treatment sets for two participants, whereas increases in accurate irregular verb production in naturalistic contexts were not observed.
Outcomes demonstrated support for a pattern-based approach to target selection for treatment of irregular past tense verbs. One participant, who demonstrated general difficulty with the probe and treatment tasks, showed no treatment effect, suggesting that the treatment may be effective for some children with DLD. Further research is warranted to determine what factors might have influenced these variable outcomes across participants.

方法:在跨行为和参与者的多个基线设计的背景下,向三名7岁的DLD参与者提供治疗。语音图式包括元音变化,最终肺泡,和双重改变不规则动词。使用既定的治疗方法提供治疗,包括叙事生成,句子模仿,和自然主义的游戏活动。在会议开始时评估了处理和未处理目标的获取,在整个治疗过程中观察到动词在自然主义语境中的使用。
结果:三个参与者中有两个发现了积极的获取效应。在两个参与者的治疗集之内和之间发生了对未治疗项目的推广,而在自然主义语境中,没有观察到准确的不规则动词产生的增加。
结论:结果证明支持基于模式的目标选择方法来治疗不规则过去时动词。一名参与者,他们在探测和治疗任务上表现出普遍的困难,没有显示治疗效果,提示该治疗可能对一些患有DLD的儿童有效。需要进一步的研究来确定哪些因素可能影响了参与者的这些变量结果。
