- Description: There is preliminary support for internet-delivered cognitive behaviour therapy (iCBT) as a way of improving access to treatment among older adults with anxiety. The aim of this randomized controlled trial (RCT) was to examine the efficacy, long-term outcomes, and cost-effectiveness of an iCBT program for adults over 60. years of age with anxiety. Successful applicants were randomly allocated to either the treatment group (n= 35) or the waitlist control group (n= 37). The online treatment course was delivered over 8. weeks and provided with brief weekly contact with a clinical psychologist via telephone or secure email. Eighty-four percent of participants completed the iCBT course within the 8. weeks and 90% provided data at posttreatment. Significantly lower scores on measures of anxiety (Cohen's d=. 1.43; 95% CI: 0.89 - 1.93) and depression (Cohen's d=. 1.79; 95% CI: 1.21 - 2.32) were found among the treatment group compared to the control group at posttreatment. These lower scores were maintained at 3-month and 12-month follow-up and the treatment group rated the iCBT treatment as acceptable. The treatment group had slightly higher costs ($92.2; 95% CI: $38.7 to $149.2) and Quality-Adjusted Life-Years (QALYs. =. 0.010; 95% CI: 0.003 to 0.018) than the control group at posttreatment and the intervention was found to have a greater than 95% probability of being cost-effective. The results support iCBT as an efficacious and cost-effective treatment option for older adults with symptoms of anxiety. © 2014 Association for Behavioral and Cognitive Therapies.

- Description: Self-guided internet-delivered cognitive behavior therapy (iCBT) has considerable public health potential for treating anxiety and depression. However, no research has examined the use of self-guided iCBT, that is, treatment without contact with a clinician, specifically for older adults. The aim of the present study was to undertake a preliminary examination of the acceptability, efficacy and health economic impact of two entirely self-guided iCBT programs for adults over 60. years of age with anxiety and depression. Two separate single-group feasibility open trials of self-guided iCBT were conducted, the Anxiety Trial (n. =. 27) and the Depression Trial (n. =. 20), using the control groups of two randomized controlled trials. The online treatment packages consisted of five online educational lessons, which were delivered over 8. weeks without clinical contact. Participants rated the interventions as acceptable with more than 90% reporting the course was worth their time and more than 70% of participants completing at least 3 of the 5 lessons within the eight weeks. Significant reductions on measures of anxiety (Generalized Anxiety Disorder 7-item; GAD-7) and depression (Patient Health Questionnaire 9-item; PHQ-9) were observed from pre-treatment to post-treatment in both the Anxiety Trial (GAD-7 Cohen's d=. 1.17; 95% CI: 0.55 to 1.75) and the Depression Trial (PHQ-9 Cohen's d=. 1.06; 95% CI: 0.33 to 1.73). The economic analyses indicated that there was statistically significant improvement in health-related quality of life compared to baseline and marginally higher costs associated with treatment for both the Anxiety Trial ($69.84; 95% CI: $4.24 to $135.45) and the Depression Trial ($54.98; 95% CI: $3.84 to $106.12). The results provide preliminary support for the potential of entirely self-guided iCBT for older adults with anxiety and depression and indicate larger scale and controlled research trials are warranted.
