OBJECTIVE

To explore the experiences of children with type 1 diabetes and their parentstaking part in an artificial pancreas (AP) clinical trial during a 7-day summer camp.

RESEARCH DESIGN AND METHODS

A semistructured interview, composed of 14 questions based on the TechnologyAcceptanceModel, was conducted at the end of the clinical trial. Participants alsocompleted the Diabetes Treatment Satisfaction Questionnaire (DTSQ, parent ver-sion) and the AP Acceptance Questionnaire.

RESULTS

Thirty children, aged 5–9 years, and their parents completed the study. A contentanalysis of the interviews showed that parents were focused on understandingthe mechanisms, risks, and benefits of the new device, whereas the children werefocused on the novelty of the new system. The parents’ main concerns aboutadopting the new system seemed related to the quality of glucose control. Themean scores of DTSQ subscales indicated general parents’ satisfaction (44.24 6

5.99, range 32–53) and trustful views of diabetes control provided by the newsystem (7.8 6 2.2, range 3–12). The AP Acceptance Questionnaire revealed thatmost parents considered the AP easy to use (70.5%), intended to use it long term(94.0%), and felt that it was apt to improve glucose control (67.0%).

CONCLUSIONS

Participants manifested a positive attitude toward the AP. Further studies arerequired to explore participants’ perceptions early in the AP development toindividualize the new treatment as much as possible, and to tailor it to respondto their needs and values.

As type 1 diabetes management moves toward the development and integration ofnew technologies, it becomes more critical to consider the psychological factorslikely to play a significant role in the use of these devices (1). Understanding psy-chological implications and managing expectations are particularly important in thecase of artificial pancreas (AP) technology. As noted by Barnard et al. (2), from a

psychosocial perspective, the AP isunique in taking responsibility for glu-cose concentrations, and it is this trans-fer of trust, along with the burden ofmultiple devices, novelty, and the day-to-day user requirement that makes ac-ceptance of AP technology a challenge.For these reasons, the impact of APtechnology requires a specific evalua-tion of related psychological implica-tions: the opportunity to assess humanfactors and effects on the lived experi-ence is the only way to reduce the risk ofproducing technologies that may be fitfor “glycemic” purposes but unfit for“lived experience” (2,3).Within the existing literature exam-

ining the psychosocial aspects of APtechnologies, most studies have beenperformed on adults. In these studies,participants who directly (4,5) and indi-rectly (by a “paper case description”)(6,7) experienced AP systems, describedthe positive impact of the tested APtechnology, positive attitudes, and ahigh likelihood of future acceptance.Similarly, the evaluation of the parentalfeelings of children and young peoplewith type 1 diabetes about diabetesmanagement through overnight closedloop insulin delivery, revealed trustand a positive attitude toward the newtechnology (8). Barnard et al. (9) evalu-ated the experiences of adolescentswith type 1 diabetes (and their parents)who took part in an overnight closed-loop study in a home setting, and foundthat the psychological and physicalbenefits of the closed-loop system out-weighed the practical challenges report-ed. The two existing studies (10,11)assessing the impact of an AP systemon children under real-life conditionsdescribed reductions in worries abouthypoglycemia and regimen burden, ahigh level of satisfaction, and an in-creased perceived ease of use of thenew technology.In light of the acknowledged impor-

tance of the psychosocial side of AP sys-tems and the critical role that humanfactors play in the adoption and efficientuse of this system, the aim of this studywas to evaluate the experiences of chil-dren with type 1 diabetes (and their par-ents) who took part in an AP clinical trialover multiple days in a diabetes campsetting. It was assumed that the adop-tion and maintenance of a new healthcare regimen is highly dependent on the

subjective perceptions of potentialusers, here including children and theirparents. Since there are currently no ex-isting validated and reliable measuresthat specifically assess the psychosocialaspects of AP systems, variables of theTechnology Acceptance Model (TAM)(12,13) and diabetes treatment satisfac-tion were considered in the currentstudy. The TAM, providing a general ex-planation of the intention to use a spe-cific system, has been adopted as atheoretical framework that can explainand identify psychological variablesthought to be key factors for under-standing and identifying the humanfactor side of AP technology (6,12).Treatment satisfaction is regarded asan important factor in the managementof type 1 diabetes and is assumed toplay a crucial role in predicting adher-ence to a new diabetes regimen, sinceits absence is considered to be a barrierthat is likely to interfere with the opti-mal use of and therapeutic benefitsfrom this technology.

The current study included a two-feature method approach: a semistruc-tured interview to evaluate participants’experience and perceptions of AP tech-nology, and psychosocial questionnairesto assess AP treatment satisfaction andacceptance.

RESEARCH DESIGN AND METHODS

ParticipantsThe participants included 33 childrenand 37 parents (some children were ac-companied by both parents) attendinga diabetes camp for an AP clinical trial.They were recruited from five Italianpediatric centers in Verona, Milano, Tor-ino, Napoli, and Roma. Inclusion criteriawere as follows: age 5–9 years; a diag-nosis of type 1 diabetes for at least12 months; use of an insulin pump andsensor for $3 months; HbA1c level,10%; a family proficient in continuoussubcutaneous insulin infusion/sensor-augmented pump; and the willingnessto send at least one parent to thecamp. Exclusion criteria were diabeticketoacidosis or severe hypoglycemiawithin the last month; concomitant dis-ease; and any medication use or condi-tions that could influence metaboliccontrol, compromise safety, or preventstudy completion. This was an open-label, randomized, crossover trial com-paring 3 days with an AP to 3 days of

parent-managed sensor-augmented pumpuse during a 7-day camp. Therewas a 1-daywashout period between the two treat-ments. Diet and physical activities (staticin the morning and moderate-to-high in-tensity in the afternoon) were kept asconstant as possible during the two studyperiods. The camp also hosted five pedi-atric diabetologists, three diabetolog-ists who were responsible for thestudy, and four bioengineers. Giventhe young age of the children, eachfamily was housed together. Duringthe 3 days of AP use, the system wasused continuously, except for the timeneeded for personal hygiene. As a re-sult, the AP remained fully operational97% of the time. When the AP systemwas active, the study team constantlymonitored the participants through atelemedicine system. More detailsabout the methodology and results ofthe trial have been described previously(14).

Semistructured InterviewTo explore participants’ experience andperceptions of AP technology, a semistruc-tured interviewwasdesignedbasedon theTAM (12,13). In particular, by making ref-erence to the questions used by van Bonet al. (6), for which there is no validatedtranslation for the Italian population, a sur-vey with 14 items adapted for both adultsand childrenwas constructed.Anoverviewof the methods used to develop the semi-structured interview and its contents isgiven in Supplementary Appendix 1. After3 days of AP treatment, a psychologist con-ducted the interviews individually, face toface; the interviews were audio recordedand then transcribed literally. When bothparentswere present, only one parentwasinterviewed.

Questionnaire DataAt the end of the AP treatment periods,the participants’ parents were askedto individually complete the DiabetesTreatment Satisfaction Questionnairefor parents (DTSQ-parent) (15) and theAP Acceptance Questionnaire (7).

The DTSQ-parent version (15) is basedon the widely used eight-item DTSQ foradults (16,17) that was developed andexpanded using extended interviewwork with parents of individuals withtype 1 diabetes. The DTSQ-parent is a14-item measure that enables self-reporting by parents of the satisfaction

about the current treatment of theirchildren. Treatment satisfaction is thecombined score of the 10 items (items1, 5–9, and 11–14) evaluating satisfac-tion, ease, flexibility, school day, medi-cal support, and continued treatment.The remaining questions relate to per-ceived frequencies of hyperglycemiaor hypoglycemia (items 2–4) and theeffects of the current treatment onthe parents’ life (item 10). All items arerated from 0 (very unsatisfied) to 6 (verysatisfied), and the range of the totalscore is 0 to 84, with higher scores in-dicating better satisfaction. The authorwas initially contacted for permissionto use the DTSQ-parent and for a copyof the instrument itself, and then theItalian version was constructed. It shouldbe specified that a trial-specific versionof DTQS-parent was used, with specificamendments suggested and authorizedby the author herself to make the ques-tionnaire appropriate for the aims of thecurrent study. For example, the clarifica-tion wording “past 3 days” has beenadded to replace “current treatment”in some items of the original DTSQ-parent(Supplementary Appendix 2).The AP Acceptance Questionnaire,

based on the TAM, was developed toexamine the future acceptance of anAP (7). It included 15 items measuringintention to use (items 1 and 2), perceivedusefulness (items 3–10), perceived ease ofuse (items 11–13), and trust in AP (items14 and 15). The questionnaire was trans-lated into Italian fromaprevious study (18)using a forward-back translation proce-dure. For the current study, the question-naire, which usually addressed patients,was modified to also fit the parents. An-swers were given on a 7-point Likert scale,where 0 = strongly disagree, 1 = moder-ately disagree, 2 = somewhat disagree, 3 =neutral, 4 = somewhat agree, 5 = moder-ately agree, and 6 = strongly agree. Ahigher total score indicates higher APacceptance (range 0–90). Further infor-mation on items of the AP AcceptanceQuestionnaire can be found in Supple-mentary Appendix 3.

Data AnalysisThe statistical analysis was performedwith Statistical Package for the SocialSciences (SPSS) version 21.0 for Macin-tosh. Frequencies or descriptive statisticswere run for demographic informationand data from questionnaires.

To quantitatively analyze the inter-views, computerized textual analysiswas applied to the textual corpus ob-tained from the verbatim transcript(both parents’ and children’s answers)of the semistructured interviews. Theparticipants’ answers were copied andcorrected for grammatical errors andpasted into a text file. The namesand surnames of the participants weredeleted. This remaining text constitutesthe text corpus. Textual analysis of theparticipants’ answers was conductedusing a content analysis software pack-age called T-Lab 5.1 (19). Two of thefunctions of T-Lab were used in this re-search: co-occurrence analysis (compu-tation of word association and sequenceanalysis of key words); and thematicanalyses of elementary contexts (ECs).To explore participants’ subjective per-ceptions of AP, a computation of wordassociation was first used to analyze therelationship between theword “AP” andeach other word in the corpus, identify-ing which concepts were most fre-quently associated with “AP” in theentire text, both in parents’ and in child-ren’s interviews. An association chart ofthe word “AP” was constructed withT-Lab to give an impression of the con-textual use of that word in terms ofwhich other words the term under con-sideration often co-occurred. The rela-tive closeness of one word to anotherword in the chart was assessed accord-ing to a parameter called the cosinecoefficient. The sequence analysis iden-tified the key words that are closer tothe word “AP,” selecting the wordswith the highest probability of preced-ing and succeeding the word “AP” inboth parents’ and children’s interviews.

Next, a thematic analysis of ECs wasconducted to identify the content of themain corpus through a small number ofsignificant thematic clusters emergingfrom the text. The clusters divided thetext into a number of themes that rep-resent the content of the narrative. Eachcluster was labeled based on the quali-tative interpretation performed by ana-lyzing the ECs grouped in each themeand the words connected to each clus-ter. Thematic clusters were internallyhomogeneous and externally heteroge-neous. Because of the shortage of textprovided by the children’s interviews,this analysis was performed only on par-ents’ answers.

RESULTS

Study Sample CharacteristicsOf 33 enrolled children, one discontinuedparticipation because of a febrile illness,one because of the illness of the parentattending the camp, and one because ofpoor acceptance of camp lifestyle. In total,30 children (19 males) and their parents(N = 34) completed the study (mean age7.66 1.2 years, mean bodyweight 26.066.1 kg, mean height 123 6 8 cm, meanBMI 16.9 6 2.1 kg/m2, mean BMI z-score 20.09 6 0.91, mean HbA1c 7.3 60.9% [576 10mmol/mol], mean durationof type 1 diabetes 4.76 1.6 years, meanpumpuse for 3.361.9 years, andmean totaldaily insulin use of 20.3 6 6.2 units/day(0.78 6 0.16 units/kg/day)] (14).

Semistructured InterviewAltogether, 27 parents (22 mothers) and27 children were interviewed. Sevenparents were not interviewed becausethey were not available during the in-terview period (e.g., they were resting).Only three children refused to be inter-viewed because they were unwilling toleave their current activity.

The concepts most frequently associ-ated with the word “AP” in the entiretext, both in parents’ interviews (Fig.1) and in children’s interviews (Fig. 2),were identified. The higher the cosinecoefficient of a word with respect tothe word “AP,” the closer that word ispositioned to the center of the figure.

Table 1 displays a sorted list of prede-cessors and successors of the word “AP”in parents’ and children’s interviews. Thelist is shown in descending order accord-ing to the probability values (Table 1,Prob.). For example, Table 1 shows thatthe probability that the parents’ answersincluded the word “son” after the word“AP” was 0.033.

The output of the thematic analysesof the ECs resulted in a structure of thefollowing four thematic clusters: check,using, glycemic control, and change. Table2 shows the four thematic clusters, listingthe x2 test values of the most importantlexical units in each cluster. A high x2 valuemeans that the corresponding lexical unitwas central to a cluster.

The four clusters contain words under-lying the parents’ main attitude towardthe use of AP concerning the properties

of the device. Especially in the “change”cluster, some positive aspects and advan-tages of the new technology were empha-sized (e.g., “curiosity,” “new,” “intriguing,”and “positive”). The remaining clustersshowed other positive views concerninggeneral type 1 diabetes management,such as medical examination, frequency

of physician office visits, and diabetescheck data (cluster “check”: “for me/ok,”“reducing,” “improving,” and “better”); APmanagement and related issues and fig-ures involved in this process (cluster “us-ing”: “learning,” “engineer,” and “easy”);and all contents related to the blood glu-cosemonitoring, such as nocturnal glucose

control and glucose level variation control(e.g., resulting from food intake) (cluster“glycemic control”: “peace of mind,” “tobe glad,” and “calm”).

Focusing on words referring to keytroublesome aspects of the AP, themain concerns included the psychologi-cal burden related to the constant effort

used to the new system (cluster “using”:“being alarmed” and “help”; cluster“change”: “disadvantages,” “difficult,”and “tired”).

Based on the overall number of ECs,the largest cluster was “glycemic con-trol” (31.6%), followed by “using”(27.7%), “change” (26.5%), and “check”(14.2%).

Questionnaire DataThe DTSQ-parent was completed by29 parents (11 fathers and 18 mothers).

Five parents did not complete the ques-tionnaire because they were not avail-able during the administration period.The mean scores of the Treatment Sat-isfaction (44.24 6 5.99, range 32–53)and Perceived Diabetes Control (7.8 62.2, range 3–12) subscales indicated ageneral satisfaction and trustful viewsof type 1 diabetes control provided bythe new system among parents.

was completed by 34 parents. Most par-ents (94.1%) noted the intention fortheir child to use the AP in the longterm (85.3% strongly, 8.8%moderately).Furthermore, 67.6% felt strongly and23.7% moderately that the AP wouldimprove their child’s glucose control;70.6% believed strongly and 26.5%moderately that it may reduce the fre-quency of hypoglycemia in their child;and 52.9% believed strongly and 26.5%moderately that it may prevent hyper-glycemia. Of the parents, 70.5% consid-ered AP easy to use (52.9% strongly and17.6% moderately) and 82.4% (47.1%strongly and 35.3% moderately) thoughtthat their children could handle it. Parentshad trust in the system, with 64.7% notingthat the AP will administer the rightamount of insulin and 76.5% believingthat the blood glucose level measured bysensor was correct.

CONCLUSIONS

This study investigated the psychologi-cal aspects of AP technology during day-and-night use. Assessing participantsattending diabetes summer camp, wherethey were able to experience aspects ofhow an AP would work in their daily lifesetting, rather than tightly controlled ex-perimental conditions, allowed for directand more realistic analysis of their sub-jective experience. In addition, sincethere are currently no existing validatedand reliable measures that specifi-cally address the needs of AP as a noveltechnology, a computerized text analysiswas performed for the first time on par-ticipants’ interview answers to betterunderstand and identify the psychologi-cal aspects of the new technology. Auto-matic text analysis has already proven tobe a powerful tool for helping chronicdisease researchers understand the ty-pology and nature of the responses,and the needs of those who are directlyaffected by a severe illness (22,23).In line with evidence from studies

evaluating the impact of the AP testedtechnology (4–7,10,11), the currentresults suggest a substantial positive

experience and approach of participantstoward the AP. In particular, the analysisof participant interviews showed thatthe parents are mainly focused on un-derstanding the mechanisms of thenew device, the risks and benefits of us-ing it in daily diabetes care, and the as-sociated need to obtain assurancesregarding the safety of using the AP inmanaging hypoglycemia. This is clearfrom an analysis of the most relevantwords surrounding the word “AP” (“in-sulin,” “hypoglycemia,” and “meal” fol-lowed by “ immediately,” “basal,”“working,” “sensor,” “child,” “night,”“seeing,” “managing to,” and “school”),and by the words identified as its mainpredecessors (“hypoglycemia,” “using,”“safe,” and “management”) and succes-sors (“managing to,” “seeing,” and “in-tervening”). The children’s perspectivewas characterized by curiosity aboutthe new system as revealed by themost relevant words surrounding theword “AP” in children’s answers (“see-ing/monitoring,” “asking,” “telephone,”“beautiful,” “experience,” “glycemia,”“touching,” “parent,” “teacher,” “new,”and “increasing”), and by its predecessors(“seeing/monitoring,” “trying,” “new,”“easy,” and “beautiful”) and successors(“beautiful,” “telephone,” “new,” and“easy”).

Evaluation of the most frequenttopics in parents’ interviews confirmsthe crucial role that the efficacy of gly-cemic control provided by the new sys-tem played in the parents’ perceptions.The analysis of the lexical units con-nected to the cluster “glycemic control”shows, in fact, that, along with the hopeof better quality of life (“autonomy,” “tobe glad,” “sleeping,” “advantage,” and“calm”), there were some concerns inadopting the new system, already de-scribed in the existing literature (4,6,9),related to the quality of glucose controlthat the new system would provide, es-pecially during nocturnal sleep (“night,”“hypoglycemia,” “peace of mind,” “in-tervening,” and “constant”). Thesedoubts and uncertainties were mostlikely caused by several factors, such asthe fear of changing the usual (and well-known) diabetes regimen, the lack of ex-perience with the new technology, andthe challenges in using a new therapywith related loss or passage of treatmentresponsibility from the parent to a tech-nological device. The weights of the

“using” and “change” clusters providefurther information regarding the rele-vant components shaping parents’ per-ception, such as the commitment andeffort requested of the child and familyin learning and growing accustomed tothe functioning of a new system (“new,”“difficult,” “to get used,” “tired,” and“changing” in the “change” cluster;“help,” “learning,” “easy,” and “time”in the “using” cluster), with related is-sues (i.e., inconvenience of the size ofthe device: “bringing” in the “change”cluster; risks: “to be alarmed,” “relyingon” in the “using” cluster; and “disad-vantages” in the “change” cluster), thepotential need to involve specific figuresto the aim of a proper use of AP (“help,”“engineer,” “relying on,” and “teacher”in the “using” cluster), and curiosity to-ward the new technology (“curiosity,”“new,” “hoping,” and “enthusiastic” inthe “change” cluster). The “check” clus-ter provides further information aboutsome of the possible effects of AP ongeneral disease management, especiallyin terms of changes of commitment andtasks (e.g., how and when to undergomedical examination, frequency of phy-sician office visits: “medical examina-tion,” “month,” “doctor,” “check up,”“times,” and “treatment”) and the re-lated psychological and emotional bur-den resulting from the novelties indiabetes regimen (e.g., the need to thinkand check, the risk of being alarmed:“thinking,” “being alarmed,” “continu-ously” “checking,” and “managing to”).

Data from the questionnaires indi-cated a general parental satisfactionand trustful views of diabetes controlprovided by the new system. Indeed,most parents believed it was easy touse and capable of providing good glu-cose control. Most parents noted theirintention to use the AP and expressed alow level of the perceived frequency ofhypoglycemia and hyperglycemia.

One limitation of this study was thesmall number of participants and theshort duration of the AP period: 3 daysof AP use may not provide a full evalua-tion of the psychological aspects and ac-ceptance of a new device created forlong-term use. Another limitation wasthat two of the used measures, the APAcceptance Questionnaire and the14-item semistructured interview sur-vey, have only preliminary empirical val-idation supporting their use in younger

patients, parents, and the Italian lan-guage. Furthermore, the subjects in-volved in the current study tended tobe highly motivated, subsequently mak-ing them less representative of the gen-eral type 1 diabetes population toprovide their perspective on an AP sys-tem. These limitations must be ad-dressed in future AP trials.In conclusion, these findings identify

the perceptions and emotions of partic-ipants about using the technology, andtheir ability to trust the new system.These aspects have been shown to becritical to the use and adherence of di-abetes technology (1,2,9), and contrib-ute to a greater understanding of thepsychological impact of AP technology.Although the parents’ concerns do notseem to affect the generally positiveapproach, they must be considered tobetter understand how to increase ad-herence to new diabetes treatmentsand to prevent potential psychologicalbarriers from reducing the likelihood ofAP technology adoption.Further studies are required to exten-

sively explore participants’ perceptionsearly in the AP development to individ-ualize the new treatment as much aspossible and tailor it to respond to theirneeds and values.
