The objective of this study was to investigate the association between personality traits of older patients and adequate home storage of drugs. Forty-four participating Dutch community pharmacists randomly selected each up to four community-dwelling elderly patients (>= 65 years) who were using at least one prescription drug. The Big Five Inventory was used to assess the personality traits - 'openness', 'conscientiousness', 'extraversion', 'agreeableness' and 'neuroticism' - of patients. An assessment of adequate home storage of drugs was made using a summed composite score for each patient ranging from zero (adequate storage) to three (inadequate storage) was based on storage criteria representing quality, information and level of storage organization. A 51.2% of the patients stored drugs adequately in accordance with all quality ("Q") and information ("I") criteria. A high level of drug storage organization was found in 70.8% of patients. Forty-three patients (31.4%) stored their drugs adequately based on all storage criteria (composite storage score 0). No associations between personality dimensions and adequate drug storage were found. Having a lower number of drugs was associated with adequate drug home storage (ORadjusted 0.86; 95% CI: 0.77-0.96). In conclusion, this study suggests that personality is not associated with adequate home storage of drugs in older patients.
