本研究包含二階段：COWMEM 發展及初步心理計量特性驗證。本研究第一 階段研究者參考Baddeley 之多系統 WM 模式設計 COWMEM，以完整地評量思 覺失調症患者之6 個 WM 向度能力，包含視空間系統、語音系統、訊息整合系統 及中央執行系統之3 種注意力：集中性注意力、轉換性注意力及分配性注意力。
COWMEM 之測驗流程包含 2 階段：施測篩檢題及施測適當難度測驗組，
COWMEM 先藉由 1 組篩檢題（6 題，各 WM 向度 1 題）初步估計受測者之 6 個 WM 向度能力，再於各 WM 向度中依據受測者之能力高低選擇 1 組高或低難度測 驗組（15 題），以更精準地評量受測者之 6 個 WM 向度能力。透過 2 階段之評估 流程，COWMEM 之總題數雖高達 186 題，然而每位受測者僅須作答 96 題（約 50%題數）。
本研究第二階段研究者初步驗證COWMEM 於思覺失調症患者之能力估計信 度、同時效度、收斂效度及已知族群效度，結果發現COWMEM 中 6 個 WM 向 度分數之信度可接受、收斂效度良好、已知族群效度中度至良好。同時效度驗證 結果發現，COWMEM 之視空間系統、語音系統及訊息整合系統測驗具可接受之 同時效度，但中央執行系統中3 種注意力測驗之同時效度尚不明確。
COWMEM 適用於思覺失調症患者團體層級之各 WM 向度能力比較，如研究 中實驗組及對照組於各WM 向度能力比較，或臨床上不同嚴重程度或病程之患者 族群於各WM 向度能力比較。此外，由於 COWMEM 之 6 個 WM 向度分數將於 所有WM 向度測驗完成後一起估計，因此未來使用者無法僅評估 COWMEM 之 單一或部分WM 向度。
