Article Abstract
Background: The apolipoprotein E (APOE) genotype provides information on the risk of Alzheimer's disease, but the genotyping of patients and their family members has been discouraged. We examined the effect of genotype disclosure in a prospective, randomized, controlled trial.
Methods: We randomly assigned 162 asymptomatic adults who had a parent with Alzheimer's disease to receive the results of their own APOE genotyping (disclosure group) or not to receive such results (nondisclosure group). We measured symptoms of anxiety, depression, and test-related distress 6 weeks, 6 months, and 1 year after disclosure or nondisclosure.
Results: There were no significant differences between the two groups in changes in time-averaged measures of anxiety (4.5 in the disclosure group and 4.4 in the nondisclosure group, P=0.84), depression (8.8 and 8.7, respectively; P=0.98), or test-related distress (6.9 and 7.5, respectively; P=0.61). Secondary comparisons between the nondisclosure group and a disclosure subgroup of subjects carrying the APOE epsilon4 allele (which is associated with increased risk) also revealed no significant differences. However, the epsilon4-negative subgroup had a significantly lower level of test-related distress than did the epsilon4-positive subgroup (P=0.01). Subjects with clinically meaningful changes in psychological outcomes were distributed evenly among the nondisclosure group and the epsilon4-positive and epsilon4-negative subgroups. Baseline scores for anxiety and depression were strongly associated with post-disclosure scores of these measures (P<0.001 for both comparisons).
Conclusions: The disclosure of APOE genotyping results to adult children of patients with Alzheimer's disease did not result in significant short-term psychological risks. Test-related distress was reduced among those who learned that they were APOE epsilon4-negative. Persons with high levels of emotional distress before undergoing genetic testing were more likely to have emotional difficulties after disclosure. (ClinicalTrials.gov number, NCT00571025.)

Disclosure and non-disclosure of childhood sexual abuse in Australia: Results from a national survey.
Child Abuse Negl
December 2024
Curtin University, Perth, Australia.
Background: Little population-based evidence exists about prevalence of lifetime disclosure and non-disclosure of child sexual abuse (CSA). Evidence is lacking about disclosure by girls and women compared with boys and men, and gender diverse individuals. It is unclear if disclosure is more common in contemporary society, and if disclosure is influenced by abuse severity and perpetrator type.

Department of Psychiatry, Chulalongkorn University and King Chulalongkorn Memorial Hospital, Bangkok, Thailand.
Background: The well-being of LGBTQ + medical students can be influenced by religiosity, family support, and the disclosure of their gender identity or sexual orientation. These factors have frequently been overlooked and warrant further consideration in creating a supportive environment for all students.
Methods: This multicenter study investigated two main outcomes including the differences in religiosity and perceived family support between LGBTQ + and non-LGBTQ + medical students in Thailand, and the gender disclosure to family among LGBTQ + medical students.
Impact of Diagnosis Nondisclosure on Quality of Dying in Cancer Patients: A Bereavement Study.
J Pain Symptom Manage
November 2024
Division of Psycho-Oncology (A.O.), Exploratory Oncology Research and Clinical Trial Center, National Cancer Center, Kashiwa, Japan.
Article Synopsis
- Patients in Japan often aren't informed about their cancer diagnoses due to cultural norms prioritizing family-oriented autonomy, which may negatively impact their quality of death (QOD) and quality of care (QOC).
- This study analyzed responses from bereaved family members to compare QOC and QOD between cancer patients who were informed of their diagnosis versus those who were not.
- Results showed that those who received a cancer diagnosis had significantly better QOC and QOD, and their families reported higher satisfaction with overall care.
Assessing and Evaluating the Perfectionism Social Disconnection Model: Social Support, Loneliness, and Distress Among Undergraduate, Law, and Medical Students.
J Psychoeduc Assess
September 2024
University of British Columbia, Vancouver, BC, Canada.
The current research evaluates the Perfectionism Social Disconnection Model (PSDM) by considering the links between measures of trait perfectionism and perfectionistic self-presentation and measures of social support, loneliness, and distress in cross-sectional research. A particular focus is on perfectionism and levels of social support as assessed by the Social Provisions Scale. The current study also uniquely evaluates levels of perfectionism and perfectionistic self-presentation in undergraduate students, medical students, and law students.
