As an online therapist, one of the key tools in your arsenal is the use of word frequency lists. These lists can significantly enhance your practice by providing a structured approach to language assessment and therapy. The research paper "Evidence-Based Selection of Word Frequency Lists" by Christopher J. Lee offers valuable insights into how to select and utilize these lists effectively.
Word frequency lists are essential for various exercises in therapy or different sets of stimuli for research. Traditionally, therapists have relied on lists like those compiled by Kucera and Francis (1967) or Carroll, Davies, and Richman (1971). However, the selection of an appropriate word frequency list is crucial for achieving accurate language assessment and effective therapy outcomes.
Key Findings from the Research
The research by Lee (2003) provides several critical insights:
- Sample Size Over Source: The study found that the size of the word sample is more important than whether the words are derived from written or spoken English. Larger samples provide more reliable frequency estimates due to reduced random error.
- Minimal Difference Between Written and Spoken English: The confirmatory factor analyses showed little justification for distinguishing between written and spoken English when selecting a word frequency list. This means that therapists can use lists compiled from either source without significant differences in their effectiveness.
- Historical and Contemporary Lists: Numerous word frequency lists have been compiled over the years, from early lists by Thorndike (1921) to more recent ones like Zeno et al. (1995). The study suggests that newer lists with larger samples should be prioritized.
Practical Applications for Online Therapy
As a practitioner, implementing these findings can enhance your therapy sessions:
- Choose Larger Samples: When selecting a word frequency list, prioritize those with larger sample sizes. For example, Zeno et al.'s (1995) list, compiled from over 17 million words, is preferable to Dahl's (1979) list, which used a sample of approximately one million words.
- Focus on Frequency Estimates: Use word frequency as a basis for estimating the level of word difficulty. This can help in designing more effective therapy exercises and research stimuli.
- Incorporate Both Written and Spoken Sources: Given the minimal differences between written and spoken word frequencies, feel free to incorporate lists from both sources in your practice.
Encouragement for Further Research
While the study provides a robust foundation, continuous research is essential for staying updated with the latest findings. Engage with current literature and consider conducting your own studies to further refine your therapy methods.
