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:BackgroundPersistent cognitive impairment is prevalent in unipolar and bipolar disorders and is associated with decreased quality of life and psychosocial dysfunction. The screen for cognitive impairment in psychiatry (SCIP) test is a validated paper-and-pencil instrument for the assessment of cognition in affective disorders. However, there is no digital cognitive screening tool for the brief and accurate assessment of cognitive impairments in this patient group.ObjectiveIn this paper, we present the design process and feasibility study of the internet-based cognitive assessment tool (ICAT) that is designed based on the cognitive tasks of the SCIP. The aims of this feasibility study were to perform the following tasks among healthy individuals: (1) evaluate the usability of the ICAT, (2) investigate the feasibility of the ICAT as a patient-administered cognitive assessment tool, and (3) examine the performance of automatic speech recognition (ASR) for the assessment of verbal recall.MethodsThe ICAT was developed in a user-centered design process. The cognitive measures of the ICAT were immediate and delayed recall, working memory, and psychomotor speed. Usability and feasibility studies were conducted separately with 2 groups of healthy individuals (N=21 and N=19, respectively). ICAT tests were available in the English and Danish languages. The participants were asked to fill in the post study system usability questionnaire (PSSUQ) upon completing the ICAT test. Verbal recall in the ICAT was assessed using ASR, and the performance evaluation criterion was word error rate (WER). A Pearson 2-tailed correlation analysis significant at the .05 level was applied to investigate the association between the SCIP and ICAT scores.ResultsThe overall psychometric factors of PSSUQ for both studies gave scores above 4 (out of 5). The analysis of the feasibility study revealed a moderate to strong correlation between the total scores of the SCIP and ICAT (r=0.63; P=.009). There were also moderate to strong correlations between the SCIP and ICAT subtests for immediate verbal recall (r=0.67; P=.002) and psychomotor speed (r=0.71; P=.001). The associations between the respective subtests for working memory, executive function, and delayed recall, however, were not statistically significant. The corresponding WER for English and Danish responses were 17.8% and 6.3%, respectively.ConclusionsThe ICAT is the first digital screening instrument modified from the SCIP using Web-based technology and ASR. There was good accuracy of the ASR for verbal memory assessment. The moderate correlation between the ICAT and SCIP scores suggests that the ICAT is a valid tool for assessing cognition, although this should be confirmed in a larger study with greater statistical power. Taken together, the ICAT seems to be a valid Web-based cognitive assessment tool that, after some minor modifications and further validation, may be used to screen for cognitive impairment in clinical settings.
