该评论表明，最常研究的治疗总体反应率方面的强度（剂量频率）可能往往较弱或有条件。为了提高弱效应检验的统计功效，通常使用累加统计模型。然而，乘法模型可能是了解剂量频率对儿童言语和语言发展影响的更有效途径。为了说明这一点，最近的研究结果表明，剂量频率对词汇发展的影响因两个儿童特征而异。最后，建议将干预会话中教学片段的间隔作为变量纳入治疗强度的多维模型中。教学片段的间隔最终可能被证明是强度的更强大的方面之一。
This commentary suggests that the most commonly studied aspect intensity (dose frequency) on overall rate of response to treatment may often be weak or conditional. To improve statistical power of tests of weak effects additive statistical models have typically been used. However, multiplicative models may be a more productive route to understanding dose frequency effects on children’ s speech and language development. To illustrate, recent findings are presented that dose frequency effects on vocabulary development varied by two child characteristics. Finally, it is suggested that spacing of teaching episodes within an intervention session be included as a variable in the multi-dimensional model of treatment intensity. Spacing teaching episodes may eventually prove to be one of the more powerful aspects of intensity.
