Mental health services use among learning disabilities: data from a population-based study.

PURPOSE: People with learning disabilities have complex challenges and needs that differ from people without these conditions. Accessing needed health and mental health care may be affected by level of independence and severity of learning challenges. Our study examined factors and associations which impact help seeking and satisfaction with mental health care in a Canadian nationally representative sample. METHODS: Logistic regression and multinomial logistic regression was used to analyze the 2012 Canadian Community Health Survey- Mental Health (CCHS 2012) cross-sectional survey. We investigated the odds of distressed individuals (1) perceiving a need for mental health care, (2) seeking out professional mental health care, and (3) if their needs were met by mental health services. The presence of a learning disability was assessed as a moderator variable in all models. RESULTS: Distressed adults with learning disabilities did not perceive a need for mental health care as often as distressed adults without a learning disability (OR = 3.82;95%CI:1.64,8.93 vs. OR = 12.00;95%CI:9.19,15.67). Distressed adults with a learning disability weren't as likely to seek out mental health services, but were more satisfied with the mental health care they received as compared to adults without a learning disability. CONCLUSION: The findings suggest that adults with learning disabilities have unmet needs. They are less likely to perceive a need for treatment, or to seek treatment, when they are distressed. Future investigation is necessary to understand the factors that influence perceived need and treatment seeking in this under-served population.

Describing the content of trial recruitment interventions using the TIDieR reporting checklist: a systematic methodology review.

BACKGROUND: Recruiting participants to clinical trials is an ongoing challenge, and relatively little is known about what recruitment strategies lead to better recruitment. Recruitment interventions can be considered complex interventions, often involving multiple components, targeting a variety of groups, and tailoring to different groups. We used the Template for Intervention Description and Replication (TIDieR) reporting checklist (which comprises 12 items recommended for reporting complex interventions) to guide the assessment of how recruitment interventions are described. We aimed to (1) examine to what extent we could identify information about each TIDieR item within recruitment intervention studies, and (2) observe additional detail for each item to describe useful variation among these studies. METHODS: We identified randomized, nested recruitment intervention studies providing recruitment or willingness to participate rates from two sources: a Cochrane review of trials evaluating strategies to improve recruitment to randomized trials, and the Online Resource for Research in Clinical triAls database. First, we assessed to what extent authors reported information about each TIDieR item. Second, we developed descriptive categorical variables for 7 TIDieR items and extracting relevant quotes for the other 5 items. RESULTS: We assessed 122 recruitment intervention studies. We were able to extract information relevant to most TIDieR items (e.g., brief rationale, materials, procedure) with the exception of a few items that were only rarely reported (e.g., tailoring, modifications, planned/actual fidelity). The descriptive variables provided a useful overview of study characteristics, with most studies using various forms of informational interventions (55%) delivered at a single time point (90%), often by a member of the research team (59%) in a clinical care setting (41%). CONCLUSIONS: Our TIDieR-based variables provide a useful description of the core elements of complex trial recruitment interventions. Recruitment intervention studies report core elements of complex interventions variably; some process elements (e.g., mode of delivery, location) are almost always described, while others (e.g., duration, fidelity) are reported infrequently, with little indication of a reason for their absence. Future research should explore whether these TIDieR-based variables can form the basis of an approach to better reporting of elements of successful recruitment interventions.

Review of pragmatic trials found that multiple primary outcomes are common but so too are discrepancies between protocols and final reports.

OBJECTIVES: To describe prevalence of multiple primary outcomes, changes in primary outcomes and target sample sizes between protocols and final reports, and how issues of multiplicity are addressed in pragmatic trials. STUDY DESIGN AND SETTING: Individually randomized trials labeled as pragmatic, published 2014-2019 in MEDLINE and registered with ClinicalTrials.gov. RESULTS: We identified 262 final reports and located protocols for 159 (61%); primary outcomes were clearly reported in 145 (91%) protocols and 256 (98%) final reports. Thirty (19%) protocols and 38 (15%) final reports had multiple primary outcomes. Primary outcomes were present and identical in 128 (81%) matched protocol-final reports. Among 140 pairs with target sample sizes reported, 28 (20.0%) reduced their target sample size (mean 543 fewer participants per trial) and 16 (11.4%) increased it (mean 192 more participants per trial). Thirteen (29.5%) provided an explanation. Only 2 of 30 (7%) protocols and 4 of 38 (11%) final reports with co-primary outcomes explained how results would be interpreted in light of multiplicity; 21 of 30 (70%) protocols and 20 of 38 (53%) final reports accounted for co-primary outcomes in power calculations. CONCLUSION: Co-primary outcomes are common in pragmatic trials; improved transparency around design and analysis decisions involving co-primary outcomes is required.

Chronic sleep disruption induces depression-like behavior in adolescent male and female mice and sensitization of the hypothalamic-pituitary-adrenal axis in adolescent female mice.

Depression is a prevalent mood disorder responsible for reduced quality of life for over 264 million people. Depression commonly develops during adolescence and becomes twice as prevalent in females than in males. However, the mechanisms underlying adolescent depression onset and sex differences in the prevalence rate remain unclear. Adolescent exposure to stress and subsequent sensitization of the hypothalamic-pituitary-adrenal (HPA) axis contributes to mood disorder development, and females are particularly vulnerable to HPA sensitization. Repeated exposure to stressors common to adolescent development, like sleep disruption, could partially be responsible for adolescent female susceptibility to depression. To address this possibility, 80 adolescent and adult CD-1 mice (Male, n = 40; Female, n = 40) were manually sleep disrupted for the first four hours of each rest cycle or allowed normal rest for eight consecutive days. Depression-like behavior was assessed with the forced swim test. 5-HT1A and glucocorticoid receptor expression and concurrent cellular activation via glucocorticoid receptor/c-Fos colocalization were examined in various brain regions to assess cellular correlates of depression and HPA-axis activation. Both adolescent male and female mice displayed significantly greater depression-like behavior and prelimbic c-Fos expression after chronic sleep disruption than non-sleep disrupted adolescent and sleep disrupted adult counterparts. However, sleep disrupted adolescent females demonstrated greater dorsal raphe 5-HT1A expression than sleep disrupted adolescent males. Adolescent females and males had decreased medial prefrontal 5-HT1A expression after chronic sleep disruption, but only adolescent females expressed decreased hippocampal 5-HT1A expression compared to controls. Chronic sleep disruption significantly increased corticosterone release, glucocorticoid expression in the CA1, and activation of glucocorticoid immunoreactive cells in the prelimbic cortex of adolescent females but not in adolescent males. These findings suggest that chronic sleep disruption during adolescence could give rise to depressive symptoms in male and female adolescents through differing signaling mechanisms.
