Online cognitive behavior therapy for adolescents with excessive worry: a multiple baseline design feasibility study.

ABSTRACT: Background:One in twenty adolescents experience excessive worry and evidence-based psychological therapies are not sufficiently widespread to reach most of those affected. In this multiple baseline evaluation, we assess the feasibility and preliminary efficacy of a scalable, online cognitive-behavioral intervention for adolescents with excessive worry (BIP worry). Methods:Thirteen adolescents (age 13-17) with excessive worry underwent the 10-week online BIP worry intervention. The treatment also included an online intervention for parents. Completion rates, treatment satisfaction, and adverse events were measures of feasibility. Clinical outcomes included worry severity, symptoms of other anxiety and depression, and general functioning. To control for time and spontaneous fluctuations in symptoms, adolescents were randomized to a 2-, 6-, or 10-week baseline phase prior to treatment. A short measure of worry severity was administered weekly during the baseline and treatment phases. Outcomes were assessed before the baseline-phase, at pre-treatment, post-treatment, and at 1- and 3-month follow-ups. Results:Twelve of 13 included adolescents, together with their parents, participated in BIP worry, with a mean completion rate of 9.8 of the 10 treatment modules. Adolescents reported an average of 4.4 exposures per week as homework during treatment. High levels of treatment adherence, credibility, and satisfaction, and no serious adverse events were reported. Therapists averaged 21 min per week communicating with each family. Linear mixed effects models indicated significant improvements in worry, anxiety, and general functioning from pre- to post-treatment, with these gains maintained at 1- and 3-months follow-up. Reductions in worry severity during treatment were significantly larger than during the baseline phase. The results from the multiple baseline evaluation suggested an association between the introduction of the BIP worry intervention and subsequent symptom change for some but not all adolescents. Conclusions:BIP worry is a feasible and potentially effective treatment. As the treatment is scalable and involves limited therapist contact, it represents a low-cost method for treating adolescents with excessive worry and anxiety. Further investigation under randomized controlled trial (RCT) conditions is warranted.

Project description:The risk of dementia increases in patients with cognitive impairment. However, it is not clear what factors contribute to the onset of dementia in those with cognitive impairment. In this prospective cohort study, we will investigate the every-five-year incidence of cognitive impairment and prognostic factors for cognitive impairment. The Jidong cognitive impairment cohort was established from April 2012 to August 2015, during which we recruited 5854 healthy participants (55.1% male) older than 45 years (mean, 57 years). Participants received a health examination in the Staff Hospital, Jidong Oilfield Branch, China National Petroleum Corporation. Baseline data and blood samples were collected. Cognitive impairment was evaluated using the Mini-Mental State Examination, and was defined as a Mini-Mental State Examination score of less than 24. Dementia was assessed using the criteria of Diagnostic and Statistical Manual of Mental Disorders (Fourth edition), the International Working Group criteria, and the Mini-Mental State Examination score. The follow-up will continue until December 2024, during which a prognostic model will be constructed. The primary outcome is the presence/absence of dementia and the secondary outcome is quality of life. Baseline screening results showed the following: (1) Cognitive impairment was apparent in 320 participants (5.5%). These participants will be excluded from the Jidong cohort study, and the remaining participants will be followed up. (2) Of the 320 participants with cognitive impairment, there was a significantly higher prevalence of illiteracy than other education levels (35.9%, P < 0.05). Age, arterial hypertension, alcohol consumption, and passive smoking differed significantly between the cognitive impairment and healthy groups (P < 0.05). Multivariate logistic regression models showed that age (odds ratio [OR] = 1.059, 95% confidence interval [CI]: 1.044-1.074) and arterial hypertension (OR = 1.665, 95% CI: 1.143-2.427) were risk factors for mild cognitive impairment. With the increase of educational level (illiteracy, primary school, junior high school, high school, university, and above), cognitive impairment gradually decreased (OR < 1, P < 0.05). (3) This cohort study has initially screened for several risk factors for cognitive impairment at baseline, and subsequent prospective data will further describe, validate, and evaluate the effects of these risk factors on cognitive impairment and dementia. These results can provide clinical evidence for the early prevention of cognitive impairment and dementia. The study was approved by the Ethics Committee of Kailuan General Hospital of Tangshan City and the Medical Ethics Committee, Staff Hospital, Jidong Oilfield Branch, China National Petroleum Corporation on July 12, 2013 (approval No. 2013 YILUNZI 1).

Project description:The Brain in Kidney Disease (BRINK) Study aims to identify mechanisms that contribute to increased risk for cognitive impairment in patients with chronic kidney disease (CKD). We describe the rationale, design, and methods of the study and report baseline recruitment and cognitive function results.Longitudinal observational cohort study of the epidemiology of cognitive impairment in CKD. The primary aim is to characterize the association between (1) baseline and incident stroke, white matter disease, estimated glomerular filtration rate (eGFR), inflammation, microalbuminuria, and dialysis initiation and (2) cognitive decline over 3 years in a CKD cohort with a mean eGFR<45 mL/min/1.73 m(2).Community-dwelling participants 45 years or older recruited from 4 health systems into 2 groups: reduced eGFR, defined as eGFR<60 mL/min/1.73 m(2) (non-dialysis dependent), and control, defined as eGFR?60 mL/min/1.73 m(2).eGFR group.Performance on cognitive function tests and structural brain magnetic resonance imaging.Sequential cognitive and physical function testing, serum and urine biomarker measurement, and brain magnetic resonance images over 3 years.Of 554 participants, mean age was 69.3 years; 333, 88, and 133 had eGFRs<45 (non-dialysis dependent, nontransplantation), 45 to <60, and ?60 (controls) mL/min/1.73 m(2), respectively. Mean eGFR in reduced-eGFR participants was 34.3 mL/min/1.73 m(2). Baseline cognitive performance was significantly associated with eGFR in all domains except language. Participants with eGFRs<30 mL/min/1.73 m(2) performed significantly worse than those with eGFRs?30 mL/min/1.73 m(2) on tests of memory, processing speed, and executive function. Participants with reduced eGFRs overall scored worst on the Immediate Brief Visual-Spatial Memory Test-Revised.Healthy cohort bias, competing risk for death versus cognitive decline.Cognitive function was significantly worse in participants with eGFRs<30 mL/min/1.73 m(2). Future BRINK analyses will measure risk factors for cognitive decline using the longitudinal data.
