Abstract

PURPOSE

To evaluate acceptability and feasibility of a theoretically-based two-part (brief in-person + eight-week automated text-message) depression prevention program, “iDOVE”, for high-risk adolescents.

METHODS

English speaking emergency department (ED) patients (age 13–17, any chief complaint) were sequentially approached for consent on a convenience sample of shifts, and screened for inclusion based on current depressive symptoms & past year violence. After consent, baseline assessments were obtained; all participants were enrolled in the two-part intervention (brief in-ED + 8-week two-way text-messaging). At 8 weeks, quantitative and qualitative follow-up assessments were obtained. Measures included feasibility, acceptability, and preliminary data on efficacy. Qualitative data was transcribed verbatim, double-coded and interpreted using thematic analysis. Quantitative results were analyzed descriptively and with paired t-tests.

RESULTS

As planned, 16 participants (8 each gender) were recruited (75% of those who were eligible; 66% non-white, 63% low-income, mean age 15.4). The intervention had high feasibility and acceptability: 93.8% completed 8-week follow-up; 80% of daily text-messages received responses; 31% of participants requested ≥1 “on demand” text-message. In-person and text-message portions were rated as good/excellent by 87%. Qualitatively, participants articulated: (1) iDOVE was welcome and helpful, if unexpected in the ED; (2) the daily text-message mood assessment was “most important”; (3) content was “uplifting”; (4) balancing intervention “relatability” and automation was challenging. Participants’ mean ΔBDI-2 from baseline to eight-week follow-up was −4.9 (p=0.02).

CONCLUSIONS

This automated preventive text-message intervention is acceptable and feasible. Qualitative data emphasize the importance of creating positive, relevant, and interactive digital health tools for adolescents.

Introduction

Psychiatric disorders are the fastest growing reason for adolescent emergency department (ED) visits.(1) Adolescent ED patients with non-psychiatric chief complaints are likely to report psychiatric disorders, such as depression and anxiety, as well as related risk factors such as violence exposure.(24) Indeed, depression and peer violence have a bidirectional relationship in adolescents, with reinforcing negative effects on emotional and behavioral regulation.(5) Multi-session cognitive behavioral therapy (CBT) for co-occurring depression and violence may effectively reduce adolescents’ depressive symptoms (6). However, at-risk adolescents have difficulty accessing mental health services (3, 7), compelling them to rely on EDs for care. EDs are therefore increasingly encouraged to perform mental health screening and referrals.(8)

Adolescents articulate interest in text-message based mental health interventions.(9, 10) Publicly available text-message services are frequently used by adolescents during mental health crises, although to our knowledge no scholarly literature describes its use or effectiveness.(11) Text-messaging is an acceptable, reliable, and valid intervention method for adolescents on numerous topics.(12) Text-message preventive interventions are feasible among adult ED patients.(13) Advantages of a text-message mental health intervention may include obviation of barriers to accessing mental health interventions, such as transportation and stigma.(8) Automated programs also inherently offer high fidelity. Limitations to text-message interventions, such as patient concerns about confidentiality(14), may also exist.

In this manuscript, we describe a pilot study of iDOVE, “intervention for DepressiOn and Violence prevention in the ED.” iDOVE is an ED-based, brief in-person and longitudinal text-message depression preventive intervention for high-risk teens seen in the ED for any reason. To our knowledge, no acceptable, feasible, and efficacious technology-based mental health interventions exist for high-risk adolescents. This pilot study’s objective was to use mixed methods (quantitative and qualitative) to assess acceptability and feasibility, and to inform intervention refinement and future mobile interventions. Secondary outcomes are preliminary efficacy at eight weeks post-enrollment.

Methods

Study Setting and Recruitment

From June-October 2014, we recruited 16 adolescents (age 13–17; eight of each gender) from a large urban pediatric emergency department located in the northeast United States. All adolescents presenting to the ED during a convenience sample of shifts were prescreened for eligibility. Adolescents were excluded a priori if they did not speak English; had a chief complaint of suicidality, psychosis, sexual assault, or child abuse; were in police or child protective services’ custody; were unable to assent due to severity of illness or developmental disabilities; or if no parent was present. All other adolescents were approached for verbal consent/assent for a brief screen on a tablet computer, determining eligibility for the larger study. Adolescents were eligible for the study if they were at high-risk for depression, defined as mild-to-moderate depressive symptoms (Patient Health Questionnaire-9 [PHQ-9] score 5–19)(15), and a past-year history of physical peer violence (modified Conflict Tactics Scale 2nd ed. [CTS-2] score ≥ 1).(16, 17) Additionally, adolescents had to have a text-message-capable phone.

Eligible participants assented, and parents provided written consent, for the intervention and longitudinal follow-up. Enrolled participants completed a baseline survey in the ED, and a follow-up survey and semi-structured interview eight weeks post-enrollment.

Participants were incentivized using a small gift (e.g., gum) for the screening survey, $25 for the baseline survey, $10 per month for text-messaging costs, and $40 for the eight-week follow-up survey and interview. This reimbursement is on par with that used in other ED-based studies of adolescents.(17, 18)

All study materials and recruitment procedures were approved by the hospital Institutional Review Board.

Intervention Structure and Content

The intervention had two parts: a brief, in-person in-ED session; and an eight-week automated text-messaging intervention. Both components were developed and refined from motivational interviewing and cognitive behavioral therapy (CBT), existing in-person and text-message preventive interventions,(6, 12, 17, 19) and participant feedback during a formative development phase.(9, 10, 14)

The in-ED session was a 15–20 minute scripted, PowerPoint-guided session delivered by a trained research assistant (RA) (Table 1, Figure 1)(10) covering: 1) basic CBT concepts (e.g., connecting thoughts, behavior, and mood), 2) motivational enhancement for intervention engagement (e.g., personalized feedback about mood and frequency of fights), and 3) introduction to the text-message component. The RA underwent structured training in intervention theory and methods prior to recruitment. In-ED interventions were audio-recorded. Fidelity of intervention delivery was assessed by MLR, based on intervention audio-recordings, using a 56-point adherence scale based on the Cognitive Therapy Rating Scale and Motivational Interviewing Treatment Integrity Code(20).

Examples of in-ED session and text-message content

The text-message portion (programmed by Reify Health, Boston, MA) was structured to progressively enhance participants’ ability and motivation to identify feelings, modify thoughts and behavior, and engage positive social support (Table 1). Based on formative work(9, 10), three text-message content streams were created: for low-violence girls, low-violence boys, and high-violence adolescents of both genders. The streams had similar basic content, but differed slightly in types of behavioral activation activities, types of stressors, and language. “High-violence” was defined as a modified CTS-2 score higher than the mean score in the study’s formative phase. At enrollment, participants were assigned to the appropriate message stream and chose a time of day for message delivery.

Each day, participants received: 1) an automatically-delivered “mood” query, 2) an intervention message, pre-tailored to mood (defaulting to “negative mood” message if no response received within two hours). (Table 1) Participants could also request as-needed text-messages using keywords STRESSED, ANGRY, SAD.

For ethical reasons, the text-message system sent automatic replies to unexpected text-message responses, reminding participants of the lack of real-time monitoring and providing crisis hotline phone numbers. The RA checked text-message responses daily.

Measures

All surveys were completed using REDCAP.(21) At the close of the intervention, a semi-structured qualitative interview was conducted in person or over the phone.

Feasibility, Acceptability, and Usability

To measure feasibility, we report study recruitment and follow-up rates, percent of daily text-message queries answered, and distribution of participant-requested text-messages. To measure acceptability, we used a modified Client Satisfaction Questionnaire (CSQ). The CSQ contains eight questions about client satisfaction with mental health services. It has high internal consistency (α=0.91).(22) For this study, question 1 was separated into 3 parts (to separately assess satisfaction with in-person, text-message, and overall intervention).

Qualitative Feedback

Semi-structured qualitative interviews were conducted by one trained RA. Topics included in-person and text-message topics (based on categories in Table 1), text-message program structure (e.g., length, frequency), and overall strengths and weaknesses of iDOVE. Interviews were audio-recorded and transcribed verbatim.

Depressive symptoms

The Beck Depression Inventory (BDI-2) was administered at baseline and 8-week follow-up. The BDI-2 is one of the most widely used assessments of depressive symptoms and is validated for ages 13–80 (α=0.92–0.93).(23)

Potential covariates

Positive affect was measured using the positive affect subscale of the Affect Intensity and Reactivity Measure Adapted for Youth (AIR-Y) scale (α =0.90–0.94) at screening and follow-up.(24) The Violence Self-Efficacy Scale, a validated (α = 0.85) 5-item measure, assessed self-rated efficacy at avoiding fights.(25) Demographic characteristics (age, gender, socioeconomic status, race, ethnicity) were measured using items from the National Survey on Adolescent Health.(26)

Analysis

Qualitative analysis was completed using thematic analysis(27), in which categories and sub-categories related to outcomes of interest were grouped together based on deductive (pre-determined, thematic) and inductive (data-driven) codes. The coding structure was iteratively refined until researchers reached consensus on a stable coding structure. Each transcript was independently coded by MLR and JRF, then discussed to ensure comprehensiveness of coding. Coded transcripts were entered into NVivo 10 (QSR International, Melbourne, Australia). Themes arose from the most salient codes; they were independently interpreted by MLR and JRF, compared for overlap, and discussed with the larger team.

Quantitative analyses were performed using STATA MP 13 (StataCorp, College Station, TX). Descriptive statistics were calculated for all measures. Likert-scale questions regarding usability and acceptability were analyzed using percentages. To assess changes in depressive symptoms (BDI-2) and potential covariates (modified CTS-2, AIR-Y, Violence Self-Efficacy) from baseline to follow-up, paired t-tests were calculated (to account for non-independence of baseline and follow-up). Baseline-observation was carried forward for participants with missing data.(28)

Results

Feasibility, Acceptability, and Usability

Of 255 patients eligible for screening, 179 (70.2%) completed screening; 13.4% (n=24) of these were eligible for iDOVE. Eighteen (75%) consented for the study; two were withdrawn prior to initiating the intervention due to changes in eligibility. Recruitment continued until the goal of enrolling 8 females and 8 males was reached (Figure 2). Five participants received the low-violence girl message stream; six received the low-violence boy message stream; and five (2 male, 3 female) received the high-violence message stream. Mean age was 15.4 years; the majority self-identified as non-White (66%) and non-Hispanic (87.5%); 63% received public assistance (Medicaid or free lunches); 37.5% had seen a therapist, counselor, or social worker in the prior year. Eleven participants were in the ED for medical complaints, and five for injuries.

Study Flowchart

Fifteen of sixteen (93.8%) were retained at the 8-week follow-up. Interviews were conducted in-person (n=1) and over the phone (n=14).

Regarding usability, all participants replied to at least some of the 56 daily mood query text-messages (mean 44.8 [80% of total], range 5–56). Participants’ preferred time for the daily text-messages ranged from 2PM to 7PM (mean 3:38PM). Five participants (31%) requested on-demand messages (SAD, STRESSED, ANGRY) (mean 1.6 requests/participant, range 0–13). In-person ED sessions had high fidelity (mean 20/20) and competency (mean 54.8/56). Most participants (n=13, 86.67%) agreed or strongly agreed that iDOVE’s text-message system was easy to use. When asked whether iDOVE’s “various parts worked well together,” 80% (n=12) agreed or strongly agreed.

Regarding acceptability, the average rating on the modified Client Satisfaction Questionnaire was 80% (SD 15%; Cronbach’s alpha 0.95). Almost all (87%) rated both in-person and text-message portions of iDOVE as excellent or good (Table 2).

Positive Quote Negative Quote
A Welcome, if
Unexpected,
Intervention
I had no idea what I was signing
up for. Honestly, I thought it was
just gonna be asking me how
how my day was going and you
guys were gonna like put it in
some data table or something,
but the advice back was actually,
I didn’t even expect it to be as
good as it was, so, yeah, I liked it
a lot … (#15, 17 y.o. M)

Um, to be honest, I wasn’t really
expecting it….I thought it was
just going to be another day in
the ER or something like that.
[But] it was pretty interesting.
(#7, 13 y.o. F)
Yeah, I’m still kind of the same person
as I was before…I’m a very stubborn
person, you can’t change me (#16, 17
y.o. M)

The iPad I was fine with, because I
was kind of already laying there and I
was bored out of my mind … It’s just
like when we talked it was not like the
right moment, cause I was kind of
freaking out. (#10, 14 y.o. M)
Mood Check-In
Was “Most
Important”
It was a question that I don’t ever
get asked, like I get asked, “how
are you?” but that’s like not
specific enough, like, I might be
feeling good, bad, I don’t…It’s
like, kinda difficult to say how I
feel, but then when you actually
make me, that I have to actually
give an answer and be like from
one to five, generally one to
five… It makes it a lot easier and
it makes me, it helps me reflect
and see how I actually feel other
than just giving- saying “oh, I’m
fine.” (#13, 15 y.o. M)

Yeah, it’s like before I would
have a hard time like talking to
people, telling people how my
day was but I’ve been doing this
for a little bit and now it’s like, I
find it easier to talk to people, like
I can tell them how I’m doing like
if it’s a bad day or a good day.
(#14, 16 y.o. M)
I guess, um when the message that I
receive “How are you feeling today?” if
we can actually say how we are
feeling. Instead of using numbers, say
how we’re feeling (#1, 15 y.o. F)

Like [pause] like it was just like
annoying doing it every day… Yea, it
should have been like at the end of the
week, you know what I mean? (#16,
17 y.o. M)
Uplifting
Content
What I what I think about that is,
if my friend’s trying to put me
down then I’m in control of what
she or he has to say about me
and I can like take it and I can go
talk to that person and be like
“why did you say this and this
and this?” and that’s not true
instead of just blowing it out into
proport- into proportion and
getting mad and frustrated, just
go up to the person and ask
them why they would say it….
They are helpful, because it
helped me realize that I could
better – like I could make my
own decisions. (#4, 15 y.o. F)

They were, they were really
good, they helped me through,
there was one, I know there was
one incident where I wasn’t, I
was having a really bad day, and
I saw one of them that wa- that
said um, it was like, “on good
days, focus on the goals you
have for yourself and the next
stop to get there,” so it was like, I
don’t know, it just made me
happier. (#15, 17 y.o. M)
It’s like all the same it ‘cuz like I said
they’re they’re just different categories
of the same thing. (#5, 15 y.o. F)
The Conundrum
of Automation
Um, I liked the text message
more, ‘cuz I’m not really an open
person, Like, I, like, there’s
certain people I can like talk to,
but I’ve known them for like ever,
but, like, um, then the text
messaging was kind of like, I felt
kind of safe about it. Like, I’m not
really saying like what’s going
on, I’m just like putting a number,
stuff like what I felt, and then you
give information, like advice, and
then, even if it didn’t help, it was
still there. (#10, 14 y.o. M)

It was helpful in like it helped me
like emotional, because, like, it,
when I was like, it would give,
like, good feedback - when I was
saying, if I was not feeling good
or if I wasn’t feeling good about
myself or depressed or anything.
(#14, 16 y.o. M)
Like um, when you say like how you’re
feeling it would be nice if an actual
person were to write out the message
for you instead of it just being like an
automated one…. Because then it’s
just not like a randomly generated
response like someone actually
thought out like what to say to you.
(#11, 14 y.o. F)

Like, at some times it was, at times it
felt repetitive, and at other times it felt
like you didn’t really have a connection
with it, and it felt like, sorta like a
lesson at school or something, and
like… That’s not what I kinda thought it
would be like. Like, I thought it would
be like really personal. (#13, 15 y.o.
M)

1) iDOVE was Welcome and Helpful, if Unexpected

In line with quantitative findings regarding acceptability, feasibility, and usability, all participants expressed strong qualitative enthusiasm about iDOVE:

I would think ‘aw, I’m just gonna be upset all day,’ and then I’d receive a message and be like ‘hey, iDove texted me,’ and I’d just feel a little happier.” (#1, 15 y.o. F)

Almost all (13/15) felt iDOVE had been helpful in changing their thoughts, feelings, and actions. Many (10/15) cited the Cognitive Triangle when describing how change occurred: “Now I try to think before I say something and when I know I’m not in that great of a mood I try to do something to distract my mind” (#6, 17 y.o. F). The two participants who said the program was less helpful (#16, 17 y.o. M; #5, 15 y.o. F) spontaneously attributed this lack of helpfulness to their being “stubborn.”

Most participants (13/15) welcomed iDOVE’s initiation in the ED, despite not expecting a mental health intervention in this setting. Two participants, however, found it difficult to concentrate in the ED.

Many (9/15) highlighted that iDOVE was unexpectedly “simple,” particularly because it didn’t require them to “go out of my way” (#3). They appreciated that “it wasn’t just texting for fun or about drama, it was texting to help me” (#8, 14 y.o. M).

2) The Mood Check-In Was The “Most Important” Part

The daily check-in was almost universally (with the exception of #16, 17 y.o. M) articulated as a major strength. More than half (9/15) said the mood check-in was the “most important” element. They described the utility of this portion of iDOVE in multiple ways. Some appreciated its daily nature, saying that they would anticipate the check-in ahead of time. Others appreciated having to quantify their emotions.

Many (10/15) just liked knowing that “someone was listening” (#1, 15 y.o. F) to what their mood was each day, even if that “someone” was just a computer. Indeed, many commented that the anonymity of text-messaging provided allowed them to respond more honestly about their mood (see Theme 4 below).

Participants also mentioned that the queries helped them be aware of what constituted a good or bad day: “It’d be like a day-tracker almost, to see how I’m doing each day” (#15, 17 y.o. M). When asked to describe their overall perception of iDOVE, two participants used the mood query’s Likert-scale numbers to quantify its effect:

[I]t went from me like going to like 3’s every day, or 2’s, 3’s or 2’s every day… to like 5’s” (#10, 14 y.o. M)

Three participants, however, suggested they would prefer using “feeling words” (e.g., replying “happy” or “sad”) instead of a Likert scale.

3) “Uplifting” Content

Participants found messages “motivating,” “reassuring,” “uplifting,” and “empowering” (spontaneously used in 11/15 interviews). Participants highlighted messages teaching self-efficacy, cognitive modifications, and problem-solving as particularly valuable. They said these messages reminded them they could handle life choices, verbal or physical fights, or disappointments. Many (9/15) said the messages reminded them of in-ED session content.

Only two participants had negative responses to messages on self-efficacy, saying these messages were too general and anodyne.

4) “Relatability”: The Conundrum of Automation

Whether the automated program was adequately “relatable” and “personal” was a common theme. These words or their stems were mentioned by 14 participants.

Many (12/15) participants appreciated the automation, even saying that its automated nature was the “key part” (#15, 17 y.o. M) because “they won’t feel so like judged” (#4, 15 y.o. F). Despite knowing the program was automated, some participants still felt as if a person were checking in:

…even if there’s like just a machine texting me, like it was a person, you know, they’re just still supporting and then just kept reminding me to um to just think and relax myself.” (#13, 15 y.o. M)

Many (8/15) believed messages were useful even when not specifically applicable to their situation. Some (4/15), however, were concerned that automation limited iDOVE’s ability to give adequately personal advice. Some suggested the messages should respond not just to mood, but also to the specific situation that caused their mood.

So if I sent a 2 because I got in a fight with my mom it would send me a message about… something that like didn ‘t really have to do with the situation…. And it would take longer for me to kind of get myself back up than if I got a message that was like more related.” (#3, 17 y.o. F)

Some said that when iDOVE did provide situation-specific advice, it missed the mark. As iDOVE did not receive input on nor respond to each participant’s specific situation, it sometimes (according to the same participant), “was like taking advice about something that didn’t really happen.” (#3, 17 y.o. F)

To address this dilemma, a few (3/15) participants suggested more human contact, such as incorporating the ability to call or text a real person. One participant suggested using the 1–5 mood scale and then having the program ask why they answered that way (#5, 15 y.o. F).

Quantitative changes in depressive symptoms and covariates

The mean baseline BDI-2 score was 14.9 (SD 9.3), versus 9.9 at follow-up (SD 8.7), corresponding to a change from mild to minimal depressive symptoms.(23) The mean ΔBDI-2 from baseline to eight-week follow-up was −4.9 (95% CI −9.0- - 0.85, t(15)=2.6, p=0.02). Statistically significant differences were also found in the AIM score (positive affect) between baseline (53.1, SD 9.8) and follow-up (59.8, SD 14.4) (Δ6.7, 95% CI 0.75–12.6, t(15)=2.4, p=0.03), and in Violence Self-Efficacy (baseline 10.8, SD 4.6; follow-up 13.13, SD 4.13; Δ=2.38, SD 3.1; t(15)=3.1, p=0.007). Past-two-month self-reported physical peer violence (measured with a modified CTS-2) did not differ significantly between baseline (3.88 +/− 3.54) and follow-up (3.63 +/− 4.75) (p=0.8).

Discussion

This mixed-methods pilot study demonstrates that iDOVE - an innovative brief in-person session initiated during an ED visit, followed by a longitudinal two-way text-message curriculum - is acceptable, feasible, and shows promise for improving depressive symptoms among high-risk adolescents. Others have demonstrated high satisfaction and a trend toward efficacy for adjunctive mobile health interventions for adolescents engaged in longitudinal treatment. (29) To our knowledge, our study is the first to indicate the acceptability and feasibility of initiating mobile mental health interventions in the ED setting.

Although patients are enthusiastic in theory about mobile mental health interventions, they often fail to engage. (30) Our study, in contrast, showed high participant engagement. Our highly diverse ED population - mostly of minority race or ethnicity and low socioeconomic status - had high access to text-messaging (similar to American adolescents in general(31)). And of those eligible, 75% enrolled in the study.

We observed high response rates to daily assessments (80%) and high follow-up rates (94%) - despite participants being in the ED for chief complaints unrelated to the intervention topic. These engagement and retention rates are much higher than in other ED-initiated text-messaging interventions or other digital mental health interventions(13, 30, 32); for instance, one digital CBT intervention, combining in-person sessions with text-messaging, reported that only 38% of daily messages received responses.(29) iDOVE’s surprisingly high degree of engagement may be explained in multiple ways.

First, according to qualitative data, iDOVE filled an unmet need in participants’ lives. Participants described an awareness of their lack of support systems, whether because of personal or structural barriers. Our results reinforce the importance of developing accessible, developmentally-appropriate mental health preventive interventions for adolescents.(33)

Second, participants found the intervention “uplifting,” and gave both the in-person and text-message portions of the intervention higher satisfaction ratings than reported by other technology-based mental health interventions.(34) Prior literature(12, 35) and our own formative work(9, 10) emphasize the importance of a positive tone and of participant-relevant language in automated interventions. Accordingly, all aspects of iDOVE’s content and structure were iteratively refined prior to this pilot to reflect participants’ own experiences, literacy levels, and definitions of “positive” language, using a human-centric, qualitative approach.(9, 10) We suspect that this rigorous, theoretically-grounded development process and high attention to tone impacted engagement.(36)

Third, participants may have engaged because they perceived iDOVE as helpful. Others’ work suggests that perceived efficacy is a major determinant of intervention engagement.(37) Quantitatively, iDOVE is promising: reductions in depressive symptoms and improvements in potential mediators of depression (positive affect and self-efficacy in avoiding fights) were observed. Qualitatively, participants described feeling like they were helped by the intervention. Participants described easily comprehending the concepts of cognitive behavioral therapy – and even gave concrete, unsolicited examples of applying these concepts to their life. The daily mood assessment, in and of itself, may also have served as an intervention. Self-assessment has been shown to influence outcomes of therapy.(38) Participants’ active engagement with the material may both signal an intervention’s value and increase its effect.(39) Future research, including longer-term follow-ups and randomized comparisons, is critical to demonstrate true efficacy.

This study also provides an important caution for future work on digital mental health interventions. Participants articulated strong but conflicting opinions about how best to balance desires for ease of access and anonymity with the desire for a human touch and “relatability.”(10, 40) Many participants said the fact that “no one was there” was one of their most-liked aspects of iDOVE; they felt iDOVE’s automated two-way programming was adequately interactive. However, the popularity of text-message-based interventions such as CrisisText, which provide personal interactions with trained volunteers, highlight the need for additional research on blending human components into mental health technology.(11) Participants’ varying degrees of desired personalization and human contact is epitomized by the use of iDOVE’s on-demand messages: of the 30% of iDOVE participants who used this feature, most requested multiple messages. Future work may consider ways to meld a standardized, automatic curriculum with on-demand human interaction, and to test the relative value of each component. For instance, natural language processing or geospatial location data could be used as an adjunct to daily mood ratings, to improve personalization.

Limitations

The primary limitation of this mixed-methods study is that it was an open pilot study, with a small sample size and no control group. Quantitative changes in symptoms may reflect the natural course of symptomatology after an ED visit. A larger sample and a control group are necessary for conclusions about efficacy. Additionally, this study was conducted at a single site with exclusively English-speaking adolescents who had access to a cellphone. Although language and phone access were rarely criteria for exclusion, future work should better quantify the effects in a diverse population. Other recruitment sites, such as the juvenile justice system, may produce different results.

Conclusions

Participants’ high satisfaction and 80% daily engagement in this eight-week intervention emphasize the importance of creating positive, relevant, interactive, and theory-based digital health tools. To our knowledge, no prior work demonstrates the feasibility and acceptability of text-message mental health interventions in the ED. This study reinforces the appropriateness of the text-message modality for adolescent mental health; it also highlights the acceptability of initiating mental health preventive interventions for adolescents in settings where preventive needs are not typically addressed. Future work should enhance personalization of digital mental health interventions, and should test interventions in fully powered randomized controlled trials.

IMPLICATIONS AND CONTRIBUTION.

iDOVE, a brief in-person and 8-week automated text-message depression prevention intervention for high-risk adolescents, had high participant retention, text-message use, and satisfaction. Participants’ biggest concern was balancing accessibility and privacy with “relatability.” This study supports implementing text-message mental health interventions for adolescents, and provides suggestions for future interventions.
