The study was designed to determine which formats for displaying quantities, such as probabilities of treatment risks and benefits, are perceived most accurately and easily by patients. Accuracy and speed of processing were compared for six different presentation formats: pie charts, vertical bars, horizontal bars, numbers, systematic ovals, and random ovals. Quantities were used in two tasks: a choice task that required larger/smaller judgments and an estimate task that required more precise evaluation. The impacts of blue-yellow color and of a treatment-decision context on performance in the two tasks were also investigated. The study included four experiments. Taken together the results suggest that the formats best for making a choice differ from those best for estimating the size of an amount. For making a choice, vertical bars, horizontal bars, numbers, and systematic ovals were equally well perceived; pie charts and random ovals caused slower and less accurate performances. For estimating, numbers led to the most accurate estimates, followed by systematic ovals. The other four formats led to the least accurate estimates. Color and context did not alter which formats were best.

The clinical features of postpartum depression and depression occurring outside of the postpartum period have rarely been compared. The 16-item Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR 16 ) provides a means to assess core depressive symptoms. Item response theory and classical test theory analyses were conducted to examine differences between postpartum (n 5 95) and nonpostpartum (n 5 50) women using the QIDS-SR 16 . The two groups of females were matched on the basis of age. All met DSM-IV criteria for nonpsychotic major depressive disorder. Low energy level and restlessness/ agitation were major characteristics of depression in both groups. The nonpostpartum group reported more sad mood, more suicidal ideation, and more reduced interest. In contrast, for postpartum depression sad mood was less prominent, while psychomotor symptoms (restlessness/agitation) and impaired concentration/decision-making were most prominent. These symptomatic differences between postpartum and other depressives suggest the need to include agitation/restlessness and impaired concentration/decision-making among screening questions for postpartum depression.

To facilitate treatment decision-making, one aims to provide information, present it in a way that makes it as easy as possible to understand, and to help the decision-maker through the cognitive processes that result in a treatment decision. Decision aids aim to accomplish just these goals and this paper identifies practical issues that we have encountered in creating a decision aid for men with early stage prostate cancer. We highlight the results of studies we carried out to provide an empirical basis for the decision aid that we were developing. Several of the studies were designed to identify what information key players (health professionals, patients and family members) thought was important for the decision-making process. Another investigation studied methodological considerations in identifying important information. The final study focused on presentation issues. These studies, designed to explore what information was considered important, found great variability among both health care professionals involved in treating patients with prostate cancer (urologists, radiation oncologists, nurses in cancer clinics, and radiation technologists) and among the patients, themselves. The studies also showed that not all information contained within a typical category is of equal importance. A methodological study showed that the information that patients deem to be important to their decision depends on whether they are rating the information that could be provided, or questions that could be answered. Finally, presentation studies showed that the various formats used in presenting quantitative information are processed with differing degrees of accuracy and ease. Each of the above results has implications for those creating decision aids; these implications are highlighted.

Patient-reported outcome measures (PROMs) are used routinely in NHS. Traditional pen-and-paper questionnaire collection can be time-consuming for both patients and clinic staff. The purpose of the current study was to determine whether a web-based PROMs system has the potential to provide satisfactory patient compliance and whether compiled data are equivalent to pen-and-paper PROMs data. A series of 82 patients who had joint replacement surgery was identified. Each patient was contacted by letter to register on the myClinicalOutcomes.co.uk website and to follow the instructions to render an Oxford score. A second request was sent to those failing to initially register. Telephone contact was then made with non-responders to identify the reason for failed registration. Successfully collated online Oxford scores were compared with previously recorded pen-and-paper scores for each patient from a prospectively updated database. Of the 82 patients identified, 61 (74%) received a letter or were otherwise contacted by telephone. Of these, 27 (44%) patients confirmed that they had access to the Internet. A total of 21 complete sets of data were collected. On review, the available secure online Oxford outcome scores demonstrated a mean of 30.1 (SD 11.4, range: 9-47). This mean score was comparable to the pen-and-paper database mean score of 29.1 (SD 11.8, range: 9-48) for the respective patients. Of the 27 respondents with Internet access, 21 (78%) produced complete scores that were available for real-time review. Available online scores were comparable to those collected via traditional means. With increased Internet availability and improved communication, remote web-based collection of patient reported outcomes may facilitate enhanced and efficient follow-up of patients.

Duplication of chromosome 22q11.2 (LCR A-D) has been reported at higher frequencies in clinical samples than the general population, but phenotypes vary widely. Triplication (4 copies) is rare, but studying the associated phenotype may provide insight into dosage-sensitivity of the genes in this chromosomal interval. We describe a proband with a triplication, specifically a “double duplication” (two copies per chromosome) of the 22q11.2 region, while his parents and two siblings each have a single duplication (3 copies). The proband had a heart malformation, dysmorphic features, and learning and socialization deficits, whereas the other family members did not. This family illustrates that while duplication of the 22q11.2 may not be sufficient to cause clinically significant neurodevelopmental or health-related phenotypes, triplication of the same region may result in a phenotype characterized by a mild neurodevelopmental disorder, facial dysmorphism, and possibly cardiac anomalies.

Microduplication of the LCR22-A to LCR22-D region on chromosome 22q11.2 is a recurrent copy number variant found in clinical populations undergoing chromosomal microarray, and at lower frequency in controls. Often inherited, there is limited data on intellectual (IQ) and psychological functioning, particularly in those individuals ascertained through a family member rather than because of neurodevelopmental disorders. To investigate the range of cognitive-behavioral phenotypes associated with 22q11.2 duplication, we studied both probands and their non-proband carrier relatives. Twenty-two individuals with 22q11.2 duplication (10 probands, 12 nonproband carriers) were prospectively assessed with a battery of neuropsychological tests, physical examination, and medical record review. Assessment measures with standardized norms included IQ, academic, adaptive, psychiatric, behavioral, and social functioning. IQ and academic skills were within the average range, with a trend toward lower scores in probands versus non-probands. Adaptive skills were within age expectations. Prevalence of attention deficits (probands only) and anxiety (both groups) was high compared with norms. The prevalence of autism spectrum disorder was relatively low (5% of total sample). Assessment of both probands and nonprobands with 22q11.2 duplication suggests that the phenotypic spectrum with respect to neurodevelopment overlaps significantly with the general population. IQ and academic abilities are in the average range for most of the individuals with 22q11.2 duplication in our study, regardless of ascertainment as a proband or nonproband relative. Symptoms of attention deficit and anxiety were identified, which require further study. Results of this study further clarify the phenotype of individuals with 22q11.2 duplication, and provides important information for genetic counseling regarding this recurrent copy number variant.
