However, if the use of reversely keyed items is preferred in a questionnaire, one could elaborate the instructions for the reader and draw the participant's attention to negatively and positively stated items.
Collaborative filtering can be divided into two categories: Memory-based CF and Model-based CF. In Memory-based CF, recommended items are those that were preferred by the users who share the similar preferences as the target user (User-based CF), or those that are similar to the other items preferred by the target user (Item-based CF).
Feeding experiments of the marine nematode Chromadora showed that diatoms and chlorophytes were preferred food items (Tietjen and Lee 1973).
As with the Zambia team, health workers' characteristics were identified as having an influence on retention, although specific items included in the incentive packages were preferred (e.g. provision of housing).
Although further analysis suggested that a rating of the pain stimulus as "pricking" or not can equally distinguish these fiber preferences, the three item test was preferred because it is known that the multiple-choice format provides a significantly more reliable measure than the true-false format [27].
The use of "text" instead of "item wording" is preferred, since TA is performed on all the components of a PRO measure (title, instructions, items, and response categories).
It must be recognised that while single-item measures often relate well to full-scale scores and can be used to obtain a reasonably reliable estimate of global fear, they are generally poorly equipped to assess the many nuances and dimensions that characterise dental fear and for this reason psychometrically sound multi-item scales are preferred.
