                <p>Adolescents engage cognitively, emotionally, and behaviorally with smartphones. Growing evidence suggests they struggle to interact with them in moderation, which has been framed in relation to behavioral addiction as problematic mobile phone use. This study contextualized 13-15 year-old adolescents&#x2019; self-awareness of problematic mobile phone use. Focus groups were conducted with 11 adolescents who assessed themselves using the problematic use of mobile phones scale. The authors used interpretative phenomenological epistemology as a guiding framework. Audio recordings were analyzed qualitatively using a constant comparison approach. Students agreed or strongly agreed with multiple dimensions of the problematic mobile phone use construct. Four major themes emerged in relation to circumstances, factors, processes, constraints, and opportunities:

            <p>Following the release of the iPhone in 2007, estimated smartphone ownership in the United States has steadily increased to 81% in 2019 and 96% for 18-29 year-olds (

Mobile phone dependency (a.k.a. problematic mobile phone use) has grown prevalent in keeping with this surge

                </sup> For the purposes of this study, we used the definition &#x201c;problematic mobile phone use is a habitual drive or compulsion to continue to repeat a human-technology interaction despite its negative impact on one&#x2019;s well-being.&#x201d;

                    <xref ref-type="bibr" rid="ref3">3</xref>
                </sup> Among the general population, determinants and effects of problematic phone use have been studied, screening tools developed, and prevalence of mobile dependency measured.

                </sup>, adolescents comprise a notably vulnerable age group. This relates to decreased levels of self-control and low resistance to peer pressure. Steinberg and Monahan (2007) noted &#x201c;susceptibility to peer pressure in adolescence follows an inverted U-shaped curve, increasing during early adolescence, peaking around age 14, and declining thereafter.&#x201d;

                </sup> Adolescents are knowledgeable agents capable of representing and articulating the different aspects of how they interact with smartphones. Yet little work has been devoted to exploring how adolescents experience mobile phone dependency and what meanings and interpretations they attach to it.</p>
            <p>This preliminary study sought to contextualize 13-15 year-old adolescents&#x2019; self-awareness of problematic mobile phone use by exploring interconnections between mobile phone dependency phenomena, the context in which they occur (
                <italic toggle="yes">i.e.</italic>, circumstances, factors, processes, constraints, or opportunities), and participants&#x2019; subjective experiences and interpretations.

Two 90-minute focus groups were held, one for the Clinton High School cohort on June 18, 2018 and one for the Dodd Middle School cohort on July 12, 2018, in a reservable meeting room of the Henry Carter Hull Library in Clinton, CT. Author A.K. was present as a non-participatory observer. They began with 60 minutes of facilitated, semi-structured discussion, then participants watched an eight-minute video clip on social media app development before discussion resumed (

                    <italic toggle="yes">i.e.</italic>, visual, audible, or tactile alerts) bolstered excessive use by prompting phone-checking and re-prioritization of current activities. Delaying or avoiding unpleasant tasks or managing stress were also connected with extended phone use.</p>

                        <p>&#x201c;I've kind of gotten into the habit of I go to sleep at 9:00pm every night because I've been on my phone all day and I put it far away from my bed where I don't have the energy to get up and grab it. So, I put it there and it feels actually nice when I put it down because I feel like I'm just disconnected and I can be soothing and I don't have to worry about people texting me all the time. So, it feels pretty good.&#x201d; (

And that's super-unhealthy for their physical state when they're super-tired during school, they're not paying attention, they're not into it. They're sitting there falling asleep in school and they look terrible. They shouldn't be up all night on their phones. It's just unhealthy for them.&#x201d; (

            <p>Nine and six of the eleven participants agreed or strongly agreed with items representing the PUMP dimensions of 
                <italic toggle="yes">longer than intended</italic> and 
                <italic toggle="yes">great deal of time spent</italic>, respectively. We found that these phenomena occurred for our 13-15 year-olds when they were interacting with only a select number of social media or texting apps, and this was facilitated by habitual processes of evaluating and responding to notifications or checking and re-checking app content. This infers it is not the phone that drives problematic behavior, it is the apps. A significant reason that adolescents are attracted to social media apps is that they increase a sense of social inclusion and connectedness.

                </sup> Social media tech companies have capitalized on this for the sake of monetization. They compete with one another for finite attention in a zero-sum game. One example of this is Snapchat, an app where users 
                <italic toggle="yes">snap</italic> each other (
                <italic toggle="yes">i.e.</italic>, send pictures or videos with overlying captions, emojis, or animations); as of March 2020, Snapchat had 229 million daily active users and 4 billion+ snaps are sent each day (Snap Inc. First Quarter 2020 Financial Results 
                <ext-link ext-link-type="uri" xlink:href="https://investor.snap.com/news-releases/2020/04-21-2020-210949737">https://investor.snap.com/news-releases/2020/04-21-2020-210949737</ext-link>). A design feature called 
                <italic toggle="yes">Snapstreak</italic> involves two users seeing how many days in a row they can maintain snapping each other. Snapstreaks are considered an indicator of success and are viewed by adolescents as proof of friendship (Lorenz T. 17 teens take us inside the world of Snapchat streaks, where friendships live or die. Mic. 
                <ext-link ext-link-type="uri" xlink:href="https://www.mic.com/articles/173998/17-teens-take-us-inside-the-world-of-snapchat-streaks-where-friendships-live-or-die">https://www.mic.com/articles/173998/17-teens-take-us-inside-the-world-of-snapchat-streaks-where-friendships-live-or-die</ext-link>). Adolescents are often sensitive and acutely aware of their own, and peers&#x2019;, social dynamics; therefore, having tangible evidence of committed friendships that endure over time can be a meaningful source of acceptance and recognition. One of our participants shared, &#x201c;I'll get 30 Snapchat in an hour or something&#x201d;. Adolescents can be devasted if months- or year-long snapstreaks lapse that they have poured an immoderate amount of time, energy, and self-validation into. Tristan Harris has stated, &#x201c;Snapstreak is driving some teenagers nuts&#x2014;to the point that before going on vacation, they give friends their log-in information and beg them to snap in their stead&#x201d; (Harris T. What&#x2019;s Now San Francisco with Tristan Harris. 
                <ext-link ext-link-type="uri" xlink:href="https://youtu.be/YQh2FQ7MZdA">https://youtu.be/YQh2FQ7MZdA</ext-link>). Harris refers to the persuasive tactics behind Snapstreaks as hijacking techniques intended to maximize viewership and consequently advertisement revenue. In addition to these conditions and processes, peer pressure, emergent social media etiquette, and competition for approval were factors that also fed into and shaped the relevant context here. These represent reinforcers; an operant conditioning term referring to anything that strengthens or increases a behavior. Our participants recognized the pressure to conform and do what their peers are doing to be powerful and hard to resist. This manifested in the form of coercion to maintain Snapstreaks and have an active presence with multiple prevailing social media apps. Social media etiquette, in setting conventions and expectations for behavior, connects to adolescents&#x2019; group identity. This reinforcer increased app engagement by threatening a person&#x2019;s sense of belonging and how they feel about themselves in relation to their peer group. In this sense, creating and posting a distinct version of a notable social media post and competing with peers for &#x2018;likes&#x2019; is normalized and offers raised perceived social status as a reward.</p>
            <p>Almost half of the participants agreed or strongly agreed with items representing the PUMP dimensions of 
                <italic toggle="yes">activities given up or reduced</italic> and 
                <italic toggle="yes">use despite physical or psychological problems.</italic> With regard to these phenomena, adolescents&#x2019; experiences were shaped by both constraints and opportunities. Problematic use of smartphones was limited when some participants were gathered socially with close family; they acceded to restrictions placed on their phone access. In contrast, when gathered for social activities with close friends, phone interactions were prioritized and quality time forfeited. Participants could not fully rationalize this behavior. Physical restrictions on the proximity of smartphones to adolescents&#x2019; beds at night was another relevant constraint that directly impacted sleep hygiene, wellness, and next day preparedness for education. Likewise, Smetaniuk (2014) studied 301 undergraduates and found that more than 20% deprived themselves of sleep due to late-night phone use.

                </sup> Smartphone interactions provided adolescents with opportunities to delay or avoid something unpleasant (
                <italic toggle="yes">e.g.</italic>, putting off studying for a test) or to manage stress. One of our participants noted, &#x201c;You don't wanna work at school and then come straight home and start working again &#x2026; I take a little break, but sometimes I'm on my phone for a long period of time &#x2026; . I'm procrastinating, procrastinating, procrastinating, making myself more stressed for this test that I still have to study for.&#x201d; This is consistent with the understanding that we mis-regulate ourselves by believing task avoidance will make us feel better.

            <p>The 21
                <sup>st</sup> century has seen the convergence of widely accessible software apps, participatory media, and internet connectivity such that virtual learning and online coaching are no longer uncommon. Having reflected on our findings, we suggest that future studies explore the effectiveness of app-based digital coaching and management techniques to scaffold adjustments to adolescents&#x2019; habits in favor of a healthy phone-life balance. For example, Moment (Moment Health Inc., Burlingame CA) offers features suited to the contexts described here including goal-setting and guided coaching to: track phone and app usage, establish phone-free times with friends and family, stop sleeping with your phone, reduce distractions, role-model accountability, and stop aimless browsing. This could affect a novel approach to reducing mobile phone use that would place some of the impetus for change upon the adolescent and facilitate conversations between teens, parents, and care providers.</p>

            </p>
            <p>This preliminary study was limited in that it involved only two adolescent cohorts from one geographical region of the United States. A minimum sample size of twelve participants is recommended for qualitative studies to reach data saturation (i.e., the point where redundancy signals to researchers that data collection may cease).

                </sup> Given this, our sample of eleven participants isn&#x2019;t quite sufficient for us to assert that our qualitative data achieved thematic saturation. The timeline of recruitment, data collection, and data analysis for this study necessarily followed the availability of the first author A.K. while he was in medical school. The authors had intended to recruit a third group of adolescents in 2020 to increase the participant number above twelve but the SARS-CoV-2 coronavirus pandemic prevented this.</p>

            <title>Conclusions</title>
            <p>Smartphones have ensconced themselves into the everyday lives of consumers around the globe. The prevalence of problematic phone use amongst adolescents and its connection with adverse wellness is a growing public health concern because harmful behaviors established in childhood can shape one&#x2019;s subsequent life course. Context is important for most phenomena of health care and health. This preliminary study supplies a contextualized glimpse into the adolescent assessment of perceived proper versus problematic smartphone use, potentially allowing parents, educators, and clinicians to reframe their approach to this critically important topic with the adolescents themselves.</p>

                <title>Underlying data</title>
                <p>The Quinnipiac University Institutional Review Board (IRB) required that the audio recordings of our focus groups not be made publicly available because 1) the participants were minors (adolescents 13-15 years old) and may accidentally use their real names rather than their assigned anonymous designations; e.g., &#x201c;participant A&#x201d; or &#x201c;participant C&#x201d; &#x2026; etc and 2) that our small sample size increased the risk of them being identified if their voices were to be heard in conjunction with the names and locations of their Schools and dates of the study being publicly available. This requirement shaped our informed consent documents which stated that the original audio recording would not be made publicly available, but de-identified transcripts of the focus group sessions would be available upon request of the corresponding author/principle investigator.</p>
                <p>Due to the age of the participants in this study, their parents/guardians did not agree for the original audio files to be shared publicly, so these data are not available to be shared. The de-identified focus group transcript data that support the findings of this study are available from the corresponding author, DM, upon request. Readers may apply for access to the de-identified transcripts by emailing the corresponding author at

                <p>Restrictions apply to the availability of these transcript data; disqualifying criteria for access consist of the following: data will not be available to any person under the age of 18 years old; and data will not be available to any person who currently is (or formerly was) a student, teacher, or employee of the schools from which participants in this study were recruited.</p>

                    </italic>: These are excellent questions that target the details of what specific content the adolescent participants were accessing on their smartphones as well as when and how often, and further contextualize smartphone upgrades and the presence of landline phones. Unfortunately, these questions are outside the scope of the data we collected for this preliminary study. Therefore, we will not be able to accommodate this requested revision simply because we do not have the relevant information. We agree that asking and gathering answers to these questions would be important to collect for future, generalizable quantitative studies. Thank you for this suggested improvement.</p>

            <p>The manuscript explored the experiences of adolescence in managing smartphone use. This is an interesting and valuable research area in the context of the pandemic and mental health impact on adolescents. Qualitative data collection was gathered from adolescents using interpretive phenomenology to guide the research process.

            </p>
            <p> A justification of why the study was implemented among students in the chosen schools can be helpful for readers. The authors mentioned reviewing the literature and the search terms used but has not clearly presented the outcome of the review or how this contributed to the study design.

            </p>
            <p> What is the impact of watching the Youtube clip before discussion with participants? Authors did not clarify why this is needed and how it contributed to responses from participants.</p>
            <p> Developing themes, how is the data analysis phase influenced by phenomenology approach adopted for the study, this needs to be further discussed; how does this influence the findings?</p>
            <p> </p>
            <p> 
                <bold>Results</bold>
            </p>
            <p> Similarly, to the methods section, the result from the study should be presented within the framework of phenomenology approach.

                <bold>Discussion</bold>
            </p>
            <p> A limitation of the study has been discussed due to the limited participants recruited for the study. However, the discussion can be improved by discussing the impact of smartphone use on mental health of adolescents.

            <p>Is the work clearly and accurately presented and does it cite the current literature?</p>
            <p>Partly</p>
            <p>If applicable, is the statistical analysis and its interpretation appropriate?</p>

                    <italic>Author response</italic>: Thank you for this prompt to clarify why we targeted adolescents in this study. We wrote in the introduction the following to draw readers&#x2019; attention to research on problematic mobile phone use that has involved the general population and why adolescents in particular represent a vulnerable age group,</p>
                <p> </p>
                <p> &#x201c;Among the general population, determinants and effects of problematic phone use have been studied, screening tools developed, and prevalence of mobile dependency measured. [2,4-5] While the detrimental effects of problematic mobile phone use on sleep, stress, anxiety, and depression can occur at various ages [2], adolescents comprise a notably vulnerable age group. This relates to decreased levels of self-control and low resistance to peer pressure. Steinberg and Monahan (2007) noted &#x201c;susceptibility to peer pressure in adolescence follows an inverted U-shaped curve, increasing during early adolescence, peaking around age 14, and declining thereafter.&#x201d; [6]</p>

                    <italic>Author response</italic>: We conducted a comprehensive review of the literature pertaining to adolescents and problematic mobile phone use in order to make readers of aware of what was available and to highlight the lack of qualitative data for those aged 13-15. The second paragraph of the introduction describes both how we conducted the literature review and a succinct summary of its findings (highlighted in bold below), consistent with the Brief Report category of F1000 Research. The lack of qualitative data for adolescents informed our choice to pursue a qualitative research question and study design that sought to explore the context of problematic mobile phone use with 13-15 year-olds..</p>
                <p> </p>
                <p> &#x201c;We searched the PubMed database using the query &#x201c;((Smartphone OR mobile phone OR cell phone) AND (dependency OR dependence OR problematic)) AND (adolescent OR adolescence OR teenage OR youth)&#x201d; 
                    <bold>and found with regard to adolescents that studies are limited to reports of prevalence and associations with adverse wellness. More specifically: cross-sectional studies have measured prevalence of mobile phone dependency [1,7-8]; mobile phone dependence correlated positively with unintentional injuries (odds ratio = 1.452) [9]; depressive symptoms, higher interpersonal anxiety, and lower self-esteem have been correlated with problematic cell phone use [10-12]; and Walsh et al (2008) held qualitative focus groups with Australian 16-24 year-olds and found extreme attachment to phones with symptoms of behavioral addiction evident in participants' descriptions. [13] Adolescent-specific investigations are limited to mobile phone dependency prevalence [1,7]; and to correlation with depression, interpersonal anxiety, lower self-esteem, and symptoms of behavioral addiction evident. [10,13] Adolescents are knowledgeable agents capable of representing and articulating the different aspects of how they interact with smartphones. Yet little work has been devoted to exploring how adolescents experience mobile phone dependency and what meanings and interpretations they attach to it.</bold>&#x201d;&#x00a0;</p>

                    <italic>Author response</italic>: In short, this was to help elicit participants&#x2019; views on Snapstreaks. It is not uncommon in humanities or sociology qualitative research for researchers to employ the use of artifacts (i.e., something created by humans which gives information) for participants to react or respond to (Crotty, 1998; Edwards et al, 2015). These artifacts are used, along with an episodic semi-structured interviewing style, to elicit participants&#x2019; views about the subject under investigation. The nature of this type of research is inherently subjective in contrast to basic science or clinical research where data can be objectively measured. In our case, the artifact was a YouTube-hosted CBS News interview with Tristan Harris the CEO of the social media app Snapchat which uses Snapstreaks. The adolescent participants are knowledgeable agents capable of representing and articulating what they think and believe (or don&#x2019;t think or don&#x2019;t believe) about the content of the video. In so doing, we as researchers were able to better explore from the qualitative data collected, how the use of social media apps may increase excessive mobile phone use in adolescents. Our citation of the video means that readers of the article can watch it and make their own judgments.</p>

                    <bold>The primary goal of researchers during the data analysis process in a phenomenological study is to deduce meaning out of the themes identified through organizing the data, coding the data, deducing categories, identifying common themes, making interpretations, and maintaining a reflective journal. The latter is an important step on phenomenological study to address researcher bias and overall credibility. It involves maintaining field notes detailing researchers&#x2019; choices and decision-making; it serves to keep the themes generation and interpretation transparent, coherent, and simple (Chenai 2011). </bold>K.G. wrote field notes after each focus group to reflect on the participants&#x2019; observations, K.G.&#x2019;s growing insights, and how her facilitator-outsider role informed the research process. [16] Audio recordings were transcribed verbatim then subject to de-identified inductive qualitative analysis using a constant comparison approach. [17] De-identified transcripts were read, then hand-coded by assigning first-stage preliminary codes. A.K. and D.M. then met together to group similar codes into categories and identify major concepts while referencing K.G.&#x2019;s memos and field notes. Iteratively, major concepts were further organized and expressed as themes and subthemes.&#x201d;</p>

                    <bold>Phenomenological data explication involves researchers&#x2019; inferring the meaning behind participants&#x2019; words and articulating experiences through thematic statements (Bassett 2004)</bold>. Participants possessed a notable awareness of problematic smartphone use in themselves and their peers. Four main themes with associated subthemes emerged 
                    <bold>from our phenomenological data analysis processes</bold>: drivers of excessive smartphone use, with family or friends, barriers to healthier smartphone use, and nighttime habits; Illustrative quotes are identified by anonymous participant codes.&#x201d;</p>

                    <italic>Author response</italic>: Thank you for this welcome recommendation to include a short discussion of the impact of problematic smartphone use on adolescents&#x2019; mental well-being. We have added the following to the end of the first paragraph in the Discussion section:</p>
                <p> </p>
                <p> &#x201c;Problematic smartphone use has been negatively associated with adolescents&#x2019; mental well-being. Souza Pereiva et al (2020), in a study of 359 female and 308 male students aged 13-18 years, associated it adversely with physical activity levels, personal interactions, academic performance, and mood disturbances. Abi-Jaoude et al (2020) also report, &#x201c;Evidence from a variety of cross-sectional, longitudinal and empirical studies implicate smartphone and social media use in the increase in mental distress, self-injurious behaviour and suicidality among youth; there is a dose&#x2013;response relationship, and the effects appear to be greatest among girls.&#x201d; As we also noted from our participants&#x2019; responses, Abi-Jaoude et al describe smartphone app-facilitated social comparisons among adolescents that negatively affected their self-view and led to increased cyberbullying and promotion of self-harming behaviors. They call for an increase in public awareness of problematic smartphone use. The contexts highlighted by our study may help inform social policy interactions aimed at promoting safe, inclusive, and nourishing home or educational environments.&#x201d;</p>
