Childhood Adversities and Physical and Mental Health Outcomes in Adults Living with HIV: Findings from the Ontario HIV Treatment Network Cohort Study.

Abstract: We sought to estimate the prevalence of childhood adversity and examine its relationship with health outcomes among people living with HIV. Study participants included 1409 adults living with HIV and receiving care in Toronto, Canada. Data on childhood adversity, health behaviors, HIV outcome measures, depression, and health-related quality of life (HRQOL) were collected through face-to-face interviews and medical records. Statistical analyses included multivariable linear and logistic regression modeling. The prevalence of any childhood adversity was 71% (individual types ranged from 11% to 44%) and higher prevalence was associated with younger age, Indigenous or African/Caribbean/Black ethnicity, lower socioeconomic status, and higher rates of cigarette smoking and nonmedicinal drug use. Greater number of childhood adversities was associated with greater odds of depression and decreasing mental HRQOL. HIV care providers need to screen for childhood adversities and address childhood trauma within the context of HIV care.

Mental health follow-up after deliberate self-harm and risk for repeat self-harm and death.

Abstract: Morbidity and mortality after deliberate self-harm (DSH) are high, so mental health care shortly after DSH is recommended. Using population-level health data we determined the association between a mental health visit and risk for repeat DSH with or without intensive care unit (ICU) admission or all-cause death. Over two years, 23,140 individuals had emergency department treatment for DSH. Within 30 days, 10.7% had a family physician mental health visit, 17.1% visited a psychiatrist, 3.6% visited both and 68.6% neither. Individuals who received mental health follow-up had more chronic and severe mental illness and higher acuity DSH. Over five years, repeat DSH occurred in 4792 (20.7%). Repeat DSH was more common in those who had a mental health visit within 30 days. Adjusting for baseline characteristics attenuated these differences. Similar results were found for DSH with ICU admission (5.0%) and death (7.6%). More frequent follow-up was not associated with better outcome. Timely access to mental health care after DSH was poor at 31%. Follow-up care had virtually no association with subsequent risk, so treatment as usual is insufficient. Post-DSH care augmented with evidence-based interventions is required.

An Internet Resource for Self-Assessment of Mental Health and Health Behavior: Development and Implementation of the Self-Assessment Kiosk.

Abstract: Background: Standardized measurement of physical and mental health is useful for identification of health problems. Personalized feedback of the results can influence health behavior, and treatment outcomes can be improved by monitoring feedback over time. However, few resources are available that are free for users, provide feedback from validated measurement instruments, and measure a wide range of health domains. Objective: This study aimed to develop an internet self-assessment resource that fills the identified gap and collects data to generate and test hypotheses about health, to test its feasibility, and to describe the characteristics of its users. Methods: The Self-Assessment Kiosk was built using validated health measurement instruments and implemented on a commercial internet survey platform. Data regarding usage and the characteristics of users were collected over 54 weeks. The rate of accrual of new users, popularity of measurement domains, frequency with which multiple domains were selected for measurement, and characteristics of users who chose particular questionnaires were assessed. Results: Of the 1435 visits, 441 (30.73%) were visiting for the first time, completed at least 1 measure, indicated that their responses were truthful, and consented to research. Growth in the number of users over time was approximately linear. Users were skewed toward old age and higher income and education. Most (53.9%, 234/434) reported at least 1 medical condition. The median number of questionnaires completed was 5. Internal reliability of most measures was good (Cronbach alpha>.70), with lower reliability for some subscales of coping (self-distraction alpha=.35, venting alpha=.50, acceptance alpha=.51) and personality (agreeableness alpha=.46, openness alpha=.45). The popular questionnaires measured depression (61.0%, 269/441), anxiety (60.5%, 267/441), attachment insecurity (54.2%, 239/441), and coping (46.0%, 203/441). Demographic characteristics somewhat influenced choice of instruments, accounting for <9% of the variance in this choice. Mean depression and anxiety scores were intermediate between previously studied populations with and without mental illness. Modeling to estimate the sample size required to study relationships between variables suggested that the accrual of users required to study the relationship between 3 variables was 2 to 3 times greater than that required to study a single variable. Conclusions: The value of the Self-Assessment Kiosk to users and the feasibility of providing this resource are supported by the steady accumulation of new users over time. The Self-Assessment Kiosk database can be interrogated to understand the relationships between health variables. Users who select particular instruments tend to have scores that are higher than those found in the general population, indicating that instruments are more likely to be selected when they are salient. Self-selection bias limits generalizability and needs to be taken into account when using the Self-Assessment Kiosk database for research. Ethical issues that were considered in developing and implementing the Self-Assessment Kiosk are discussed.

Childhood Adversity and Hazardous Drinking: The Mediating Role of Attachment Insecurity.

Abstract: Background Harmful alcohol use is associated with disease and mortality. Identifying new determinants of harmful drinking may aid the 16.3 million adults who have alcohol use disorders. Childhood adversity is associated with alcohol use, but is not amenable to change. Attachment insecurity (anxiety and avoidance) may be associated with alcohol use and may be a target for modification or used to personalize interventions. Objectives This study aims to (a) identify the association between attachment insecurity and harmful drinking, (b) determine if attachment insecurity may mediate between childhood adversity and harmful drinking, and (c) test sex as a moderator between attachment insecurity and harmful drinking in the mediation relationship. Methods Adult primary care patients (N = 348, 60% women) completed a cross-sectional survey study using validated measures in 2012. Statistical analyses were performed using Hayes's PROCESS macro in SPSS. Results Childhood adversity was reported by 61% of the cohort and 18% endorsed harmful drinking. Attachment anxiety was associated with harmful drinking (p >.001), but attachment avoidance was not (p =.11). Attachment anxiety may mediate between childhood adversity and harmful drinking (95% CI:.03-.14). Sex did not moderate the relationships between attachment anxiety and harmful drinking in the mediation relationship (women: 95% CI:.031-.179; men: 95% CI:.003.-.182). Conclusions/Importance: Attachment anxiety may mediate between childhood adversity and harmful drinking in both men and women. Attachment anxiety may be a potential therapeutic target for people with a history of childhood adversity.
