The Brand Emotions Scale for Writers (BSEW) is a 20-item scale designed to measure the emotions of writers; (1) immediately before writing (state-before), (2) immediately after writing (state-after), and (3) when writing in general (trait). This paper describes the development of BSEW and the factor structure of these three different forms. Common factor analyses (orthogonal rotation) yielded two factors for each of the three forms (state-before, state-after, and trait when writing) accounting for 36 percent, 42 percent and 44 percent of the total variance, respectively. The item composition of the two factors, labeled positive and negative, were very similar across the three forms. The BSEW appears to be an internally consistent instrument. The paper states: (1) that research using these scales can investigate emotional change due to writing by comparing before- and after-writing emotions; (2) that these emotions can also be measured during the writing process; and (3) that mediating variables associated with any changes can be identified. The appendices contain a demographic data sheet, as well as both forms S and TWW of the BSEW. A five-page list of references is included. (Author/PN)
