Enhancing shared decision making about discontinuation of antidepressant medication: a concept-mapping study in primary and secondary mental health care.

BACKGROUND: The apparent rise of antidepressant use seems to be explained to a large extent by an increase in long-term use. Both professionals and patients appear reluctant to discontinue antidepressant medication (ADM). It is not known what factors determine this reluctance. AIM: This study aimed to identify factors that enable the shared decision-making process about discontinuation of ADM between long-term users and their GPs. DESIGN AND SETTING: Concept-mapping study of a purposive sample of both patients and professionals from primary and secondary mental health care in the Netherlands. METHOD: Concept mapping was used to conceptualise and structure the topics relevant to the discontinuation process from the perspective of both patients and professionals. Participants generated topics in brainstorming sessions and subsequently prioritised and sorted them. Multidimensional scaling and hierarchical cluster analyses were used for the cluster topics. RESULTS: Thirty-seven patients and 27 professionals generated 50 separate topics. Hierarchical cluster analysis revealed six clusters of topics: 'Process of discontinuation', 'Expectations', 'Professional guidance', 'Current use', 'Environment', and 'Side effects'. Patients and professionals came up with largely similar topics. Nevertheless, a difference was found between these groups regarding the perceived importance of professional guidance. CONCLUSION: This study yielded an informed selection of the topics that seem most important to discuss when considering whether to discontinue ADM. As perspectives of both patients and professionals were combined, the topics may provide patients and GPs with a broader and more balanced scope of factors to consider, and thus facilitate a better shared decision-making process.

Evidence for attentional processing in spatial localization.

Using a dual-task methodology, this study examined the involvement of selective attention in spatial localization. Thirty participants located a single, briefly presented, peripheral target stimulus, appearing in one of 50 positions on either side of a central fixation point, with or without the requirement to identify a simultaneously presented central distractor stimulus. Results revealed a robust interference effect in localization performance at short target durations that depended on the number of the to-be-identified distractor items. This outcome provides convergent support for the role of the attentional system in spatial localization.
