The psychometric properties of the Miller Behavioural Style Scale with adult daughters of women with early breast cancer: a literature review and empirical study Several researchers have suggested that the information‐seeking behaviours of patients need to be taken into consideration when assessing their information needs. This study reviews published evidence of the psychometric properties of the Miller Behavioural Style Scale, a tool commonly used to identify the information‐seeking behaviours of individuals under threat, and examines its reliability and validity with adult daughters of women with early breast cancer. Ninety‐seven adult daughters completed the MBSS and a 30‐item, self‐administered questionnaire, a tool designed to explore the information needs of adult daughters of women with breast cancer. The internal consistency of the monitoring and blunting sub‐scales of the MBSS was α=0·65 and 0·41 respectively. The blunting sub‐scale fell substantially below acceptable limits and was discarded from subsequent analyses. The monitoring sub‐scale possessed good test–retest reliability ( n =17) with a 5‐week time interval ( r =0·71, P < 0·005), as measured using a Pearson’s correlation coefficient. Furthermore, the majority (73·4%) of monitoring items possessed moderate or substantial test–retest reliability, as indicated by kappa coefficients. Finally, the monitoring sub‐scale possessed good construct validity, both discriminant and convergent validity, as measured by the univariate associations between monitoring behaviour and selected items from the information questionnaire and a demographic questionnaire. In conclusion, adequate support exists for the psychometric properties of the monitoring sub‐scale of the MBSS and its use with adult daughters of women with early breast cancer in future research. These findings have a number of implications for nursing research and these are discussed in this paper.
