Development and Evaluation of the Behavioral and Psychological Symptoms of Dementia Questionnaire 13-Item Version (BPSD13Q)

“…The items of the BPSD13Q were categorized into 5 factors, similar to those shown in previous studies [12,13]. "Depression" and "anxiety" are usually found in the same factor in most studies [12][13][14][15][16], and according to Phannarus et al [15], "repeating" is also included in the same factor [15]. The second factor included "irritability," "resistance to care," and "disinhibition."…”

“…“Depression” and “anxiety” are usually found in the same factor in most studies [12-16], and according to Phannarus et al [15], “repeating” is also included in the same factor [15]. The second factor included “irritability,” “resistance to care,” and “disinhibition.” Therefore, it is assumed that “irritability” and “disinhibition” are included in the same factor [12, 13], and “resistance to care” is included in the same factor as hyperactive-type behavioral symptoms [12, 13, 15, 16]. “Wondering and restlessness,” “day-night reversal,” and “stereotyped behavior” were categorized chiefly into the agitated behavioral symptoms.…”

“…The second factor included "irritability," "resistance to care," and "disinhibition." Therefore, it is assumed that "irritability" and "disinhibition" are included in the same factor [12,13], and "resistance to care" is included in the same factor as hyperactive-type behavioral symptoms [12,13,15,16]. "Wondering and restlessness," "day-night reversal," and "stereotyped behavior" were categorized chiefly into the agitated behavioral symptoms.…”

“…In this way, our results were similar to those of previous studies and are therefore structurally valid. Recently, the 14-item Thai language BPSD scoring system for dementia (BPSD-T) has been developed for nonphysician health-care personnel [15], but our evaluation scale has the advantage of being easy to use even for care staff who are often involved in the actual dementia care.…”
