(1) Background: This article discusses the first two phases of development and validation of the Three Domains of Judgment Test (3DJT). This computer-based tool, co-constructed with users and capable of being administered remotely, aims to assess the three main domains of judgment (practical, moral, and social) and learn from the psychometric weaknesses of tests currently used in clinical practice. (2) Method: First, we presented the 3DJT to experts in cognition, who evaluated the tool as a whole as well as the content validity, relevance, and acceptability of 72 scenarios. Second, an improved version was administered to 70 subjects without cognitive impairment to select scenarios with the best psychometric properties in order to build a future clinically short version of the test. (3) Results: Fifty-six scenarios were retained following expert evaluation. Results support the idea that the improved version has good internal consistency, and the concurrent validity primer shows that 3DJT is a good measure of judgment. Furthermore, the improved version was found to have a significant number of scenarios with good psychometric properties to prepare a clinical version of the test. (4) Conclusion: The 3DJT is an interesting alternative tool for assessing judgment. However, more studies are needed for its implementation in a clinical context.
RESUMEN
BACKGROUND: Although the US Food and Drug Administration (FDA) recommended upper limits for citalopram dosing in older adults due to risk of corrected-QT (QTc) prolongation, which was adopted, and extended to escitalopram by Health Canada, the scientific basis is unclear. The objective of this study was to assess the relationship between citalopram/escitalopram dosages and QTc interval in a real-world geriatric setting. METHODS: We reviewed electronic health records at a university-affiliated geriatric health care center, over a 7-year period, to identify patients prescribed citalopram and escitalopram, who had an ECG within 90 days of initiation or dosage change. Linear regression analyses were conducted to assess the relationship between antidepressant dosage and QTc interval. RESULTS: 137 patients were identified (citalopram=97, escitalopram=40). No association was found between citalopram, escitalopram and QTc, in unadjusted or adjusted analyses. Among covariates, older age was significantly associated with QTc prolongation in the escitalopram group. LIMITATIONS: Limitations to the current study include its retrospective design and the small sample size. CONCLUSIONS: These data do not support the FDA or Health Canada's recommended maximum dosages of citalopram or escitalopram in the elderly. Therefore, for patients already on higher doses of these medications, the risk of QTc prolongation may not always outweigh the risk of dose lowering, such as relapse. Until larger prospective studies become available, the decision to comply or not with these federal agencies' recommendations should be weighed on an individual basis, taking into consideration all potential risk factors.

AIM: Our case report addresses the use of clozapine in patients who have a history of quetiapine XR-induced neutropenia. There are no current guidelines for this situation. METHODS: We present the case of a young woman treated with clozapine at a first-episode psychosis clinic after a moderate quetiapine XR-induced neutropenia (0,5-1,0 × 10(9) L(-1) ). RESULTS: The patient was successfully treated with clozapine and lithium, with less psychotic symptoms and a better level of functioning. The neutrophil count remained normal during the treatment period, which has been longer than a year. CONCLUSION: The outcome of this case supports the notion that clinicians could consider introducing clozapine in treatment-refractory patients who have a history of quetiapine XR-induced neutropenia, with close blood monitoring. Lithium co-administration may play a role in maintaining a normal neutrophil count.
