Aims and objectives. This paper is a report of a study conducted to investigate differences between nurse practitioners' perceptions of the importance of required competencies and their self-evaluated existing competencies, and the main factors influencing these differences. Background. The difference between nurse practitioners' perceptions of required competencies and their existing competencies has never been investigated. Therefore, it is still uncertain whether these two competencies differ. Design. A nationwide survey study was authorised by the Department of Health (DOH) in Taiwan. Methods. For this nationwide survey study, the Questionnaire of Competencies in the Nurse Practitioner's Role was mailed to all nurse practitioners who qualified for the first annual national NP licence exam in Taiwan. Of 582 questionnaires distributed, 374 valid questionnaires were returned for a response rate of 64·2%. Results. The scores for required competencies were all higher than existing competencies. The competencies with largest differences were (in increasing order) clinical research, direct care, and leadership and reform. The competencies with smallest differences were (in ascending order) medical assistance, communication and coordination, and ethical decision-making. Differences in the total score between required and existing competencies were significantly influenced by nurse practitioners' age, seniority as nurse practitioner, whether the nurse practitioners' institution had a nurse practitioner advancement system, and the number of patients under their care. Conclusions. Nurse practitioners' perceptions of the importance of their expected role competencies were significantly greater in most cases than their actual competencies. Relevance to clinical practice. These findings could serve as a reference to improve cultivation of the NP system in Taiwan, to strengthen professional competencies in NP training programs.

Aim. This paper reports a study to investigate the relationships among bone mineral density, demographics, knowledge of osteoporosis, beliefs concerning osteoporosis and preventive behaviours of at-risk females with family histories of osteoporosis. Background. Strong evidence demonstrates that genetics is a significant determinant of peak bone mass, with a heritability of 50–90%. However, few studies have examined the bone mineral density of at-risk females with family histories of osteoporosis, particularly in an Asian population. Design. Telephone survey. Methods. The study population ( n = 2890) was recruited from a radiology department at a national university medical centre in northern Taiwan during 2005–2006. In total, 886 females completed a questionnaire via the telephone; the participation rate was 30·7%. Results. The bone mineral density of at-risk females was close to osteopenia status (T score of −1 to −2·49). Most subjects were aware of osteoporosis-related information; however, few clearly understood osteoporosis. Furthermore, subjects reported difficult implementing strategies to improve bone mineral density. Variation in bone mineral density was correlated with self-rated health ( r = 0·56, p < 0·05), knowledge of osteoporosis ( r = 0·66, p < 0·05) and preventive behaviours ( r = 0·68, p < 0·05). Conclusions. This study is to examine risk factors associated with bone mineral density of females with family histories of osteoporosis. Early identification of risk factors for osteoporosis and development of prevention programmes are required to halt the increasing in the incidence of osteoporosis and improve the bone mineral density of at-risk females. Relevance to clinical practice. Nursing care professionals, who emphasise primary, secondary and tertiary prevention with individuals and families, should develop effective prevention strategies for women with family the history of osteoporosis to protect the health of these vulnerable populations at-risk for osteoporosis.
