Pretreatment Attrition and Formal Withdrawal During Treatment and Their Predictors: An Exploratory Study of the Anxiety Online Data

“The treatment commencers differed significantly (P .001-.03) from the noncommencers on several variables (reason for registering, mental health concerns, postsecondary education, where first heard about Anxiety Online, Kessler-6 score, stage of change, quality of life, relationship status, preferred method of learning…”

“5% of the population report very high distress scores of 20-30 [33,34].”

“Researchers report attrition rates for e-mental health treatment programs for anxiety or depression ranging from as high as 99% to as low as 1% [10-14] with the majority reporting attrition rates ranging between 20% and 40%.”

“Researchers report attrition rates for e-mental health treatment programs for anxiety or depression ranging from as high as 99% to as low as 1% [10-14] with the majority reporting attrition rates ranging between 20% and 40%.”

“Although e-mental health interventions for the treatment of anxiety disorders have been shown to be effective [1-6] and increasing in popularity [7,8], research tends to be limited by high rates of attrition [8-10] and small to moderate sample sizes reported by most trials (see [11]).”

“In clinical practice, attrition rates for the treatment of anxiety disorders vary by treatment setting and definition with a range from 10% to 60% [19-21].”

“Researchers report attrition rates for e-mental health treatment programs for anxiety or depression ranging from as high as 99% to as low as 1% [10-14] with the majority reporting attrition rates ranging between 20% and 40%.”

“Only 1 study reported a higher pretreatment attrition rate of 85% for individuals with social anxiety [31], whereas 2 studies reported approximately half the pretreatment attrition value of this study: Richards and Borglin [30] for a study on anxiety and depression reported a pretreatment attrition of 27% and Issakidi…”

“Moreover, some people may not need to complete all the modules to acquire what they need to improve [37,38].”

“However, other researchers have reported no significant effect for all or some of these aforementioned variables [23,27-29].”

“Attrition appears to be greater in studies of Internet-based treatment that are open to the general public [16] and online therapy in which there is no therapist involvement [17,18] than in studies dealing with in-clinic samples and online samples in which assessors and therapists are involved.”

“In relation to formal treatment withdrawal, sex, age, income, educational level, and comorbidity were not found to be significant predictors of formal withdrawal during treatment, which is contrary to the findings of several studies [22-26].”

“In a review of the effectiveness of e-mental health treatment programs for panic disorder, attrition rates for online therapy ranged between 4% and 36% [15].”

“On the other hand, years of education, race, age, and employment status were significant predictors of attendance at the initial interview for treatment [31].”

“Demographic characteristics—Age [20, 57, 63, 68–70, 73, 76, 79, 91, 95, 96, 99, 106–111], gender [20, 69, 73, 90, 95, 100, 101, 110, 111], education [20, 69, 91, 92, 96, 99, 106, 107, 109, 110, 112], employment [91, 92, 107] and ethnicity [57, 106] were found to be significantly associated with engagement.”

“Medications/Alcohol Three studies (8 %) examined whether medication usage or alcohol intake (excluding the studies that specifically targeted alcohol use disorders) predicted adherence; none of the studies found a significant relationship [22, 30, 36].”

“Socioeconomic status markers such as education (eg, [25,27], higher more than lower) and employment (eg, [28,29], higher more than lower), age [25,30,31], older more than younger) and gender (eg, [25,27,32], women more than men) are known to influence sustained use, as are psychological traits such…”

“…significant differences between completers and dropouts may provide valuable information to identify focal points for targeted attrition reduction, although previous efforts to identify nontechnological factors influencing attrition in online interventions have yielded inconclusive results [71-75].”

“Other reasons include low material incentives [18,19], asking for personal information [20], non-familiarity with the Internet [15,21-23], or low interest and motivation to take part [24].”

“Previously, we examined pretreatment attrition and during treatment formal withdrawal and their predictors in the Anxiety Online data [34].”

“Previous research has shown there to be a significant correlation between motivation and adherence (Al-Asadi et al., 2014).”

“For example, previous studies have shown that adoption of DHIs may be less among those with low socioeconomic status, [50], less computer experience [51], and less access to social networks [52].”

“Uptake examples included those enrolled in the past 2–12 months (Silverman et al., 2023) or who began treatment (Al-Asadi et al., 2014 Interrater agreement was assessed using intraclass correlation coefficients (ICC) for continuous variables (Shrout & Fleiss, 1979) and Cohen’s kappa (κ) for…”

“Other user-speci fi c factors that have also been connected to engagement are mental health symptom severity (15, 16), motivation (4, 6, 13), self-ef fi cacy (17), treatment expectations (4), and desire for anonymity (18).”

“Based on observations regarding pretreatment attrition in CBT and IBT for anxiety disorders studies [9, 36–38], we will consider the feasibility outcome satisfactory if it is over 50 %.”

“…motivation as significant predictors of adherence to web-based mental health interventions, including intrinsic motivation [22], internal locus of control [44], expected behavioral ability to complete the program [45,46], and self-identification with “preparation” or “action” stages of change [47].”

“This finding is in line with prior research indicating that greater social support is associated with more participation in psychotherapy (Al-Asadi et al., 2014; Ayuso-Mateos et al., 2007).”

“To our knowledge, only two studies targeted PTSD in their online treatment, and neither study detected a gender effect in attrition despite using large sample sizes [2,19].”

“[3Z-13] Classified under the theme of commitment, 4 adolescents and 1 child stated they felt obligated to finish what they started.”

“…studies have examined patient characteristics (eg, age, employment, education, and marital status [9,12, 13]), social support [14,15], self-efficacy [16], and clinical factors (eg, comorbidities [13,17], well-being [18], distress, depression, and anxiety [17-20]) associated with engagement in DHIs.”
