AbstractBackground: Thedegreetowhichpatientsparticipateintheircarecanhaveaposi‐tiveimpactonhealthoutcomes.Thisreviewaimedtomapthecurrentliteratureonpatient participation behaviours in interactionswith physicians and the extent towhichdifferences in thesebehaviours canbeexplainedby socio‐economic status(SES).Search strategy: Fourelectronicdatabasesweresearchedfrom1980onwardsusingkeywordsrelatedtosocio‐economicstatusandpatientparticipationbehaviours.Study selection: Titles,abstractsandfulltextswerescreenedbytworeviewers,withthesecondreviewerscreening20%ofallentries.Data extraction: Dataonyearofpublication, country, patientpopulation, setting,patientparticipationbehaviourstudied,andSESmeasureusedwereextracted.Main results: Forty‐ninestudieswereincludedinthereview.Moststudieswerecon‐ducted intheUnitedStates,andthemostcommonlystudiedpatientparticipationbehaviourwas involvement in decisionmaking.Most studiesmeasuredSESusingeducationasanindicator,withveryfewstudiesusingoccupationasameasure.Manystudies did not report onparticipants’medical conditionor study setting. Patientparticipation in theirhealth‐careappointment increasedwith increasingSES in24studies,althoughin27studiesnosignificantassociationwasfound.Discussion and conclusions: Current literaturewasfoundtobemainlyUS‐centric.Manystudiesdidnotspecifyparticipants’medicalconditionorinwhatsettingthestudywasundertaken.Morestudiesareneededonlesscommonlystudiedpatientparticipation behaviours. Itwould be helpful for further studies to also include awiderrangeofSESindicators.

1 | INTRODUC TION
Patient‐centredcarehasbeenassociatedwithbeneficialoutcomessuchasagreateradherencetotreatment,satisfactionandimprovedqualityof life.1‐4The InstituteofMedicinedefinespatient‐centredcareasprovidingcarethat is respectfulofandresponsiveto indi‐vidualpatientpreferences,needsandvalues,ensuringthatpatientvaluesguideallclinicaldecisions.5Thus,theextenttowhichpatientsparticipateindiscussionsduringtheirhospitalorclinicvisitsisseenasanimportantbarometerofpatient‐centredcare.Althoughthereisnouniversallyapplieddefinitiononwhattypeofbehavioursconsti‐tutespatientparticipationinclinicalvisits,6moststudiesfocusingonpatientparticipationbehavioursinvolvearangeofbehaviourssuchasquestionasking,raisingconcerns,andexpressingopinions,pref‐erencesandemotions.7
Often‘patientparticipationbehaviours’aredescribedasagen‐eralgroupofbehaviours thatcharacterizedoctor–patientcommu‐nication,ratherthandescribingindetailthedifferentwayspatientparticipationcanbemeasuredorothercomponentpartsofdoctor–patient communication behaviour which are classified in a differ‐entway.Forexample,animportantprevioussystematicreviewbyVerlindeetal8focusedmoregloballyondoctor–patientcommunica‐tionbehaviours,withtheelectronicsearchtermsbasedon‘doctor–patientcommunication’and‘physician–patientrelations’.Thereviewreportedevidenceshowingthatasocialgradientindoctor–patientcommunicationexistsandclassifiedthisaccordingtothefollowingclassification:verbalbehaviourincludinginstrumentalandaffectivebehaviour, non‐verbal behaviour and patient‐centred behaviour.Although the reviewfound thatpatientswith lowsocio‐economicstatus(SES)tendedtoparticipatelessactivelyintheircare,thestudyanditssearchstrategywereinsufficientlysensitivetoallowidenti‐ficationastowhethercertainpatientparticipationbehavioursweremoreresearchedormoreimportantthanothers,sincethefocusofthestudywasdoctor–patientcommunicationingeneral.
The Verlinde et al8 review also limited identification of litera‐tureexploringthesocialgradientindoctor–patientcommunicationand social gradient, to studies reporting the ‘social class relatedconceptsof’educational level, incomeoroccupation.Confusingly,threeofthestudiesincludedinthisreviewmeasuredSESusing‘so‐cialclass’,althoughtheauthorsdidnotspecifyexactlyhowthiswasdefined.However, thereareseveralother indicatorsofSESwhichmayalsobeassociatedwithpatientparticipationbehaviours suchas thepatients’health insurancestatusor receiptofbenefits,andalsoarea‐levelmeasuresofdeprivationrelatedtothepatients’homeaddress(IndicesofMultipleDeprivation),whichmaynothavebeencapturedpreviously,andmaystillberelevant.9Bearinginmindthepotentialimportanceofthisareaanditslikelyrelationshiptobenefi‐cialhealthoutcomes,weundertookasystematicmappingreviewtoidentifywhatresearchhadbeendonewhichspecificallyexaminedhowpatientparticipationbehavioursindoctor–patientinteractionsare related todifferences inawide rangeofpossiblemeasuresofsocio‐economicstatus.

2 | PURPOSE
Our research question was as follows: How and why does ten‐dencytoanddesireforpatientparticipationbehavioursinhealth‐careconsultationswithphysiciansvaryaccordingtoSESandwhatmeasuresofSEShavebeenexplored?Forthepurposeofthisre‐view,wedefinedpatientparticipationbehavioursasconsistingofquestion asking, raising concerns, involvement in decision mak‐ing,rapportbuilding,andexpressionofopinions,preferencesandemotions.
3 | DATA SOURCES
Anelectronic searchwasundertakenof the followingdatabases:Medline,CINAHL,PsychINFOandWebofScience.Literaturewassearchedfrom1980to2018;sincepriorto1980,therewasmuchlesselectronic indexing.Apilotsearchwasconductedto identifypotentiallyeligiblepapers,assesstheamountofrelevantliteraturein the field and identify suitable search terms. At this stage,wefound that including screening appointments and emergency ad‐missionsmadethescopeofthereviewfartoobroadandunman‐ageable;therefore,wedecidedtointroducelimitsintheelectronicsearchtermsregardingongoingdoctor–patient relationships.Theelectronic search contained free text and subject headings in‐cluding patient‐centred care, question asking, raising concerns,involvement in decision making, building rapport, expression ofpreferences,emotionsoropinions,educationalstatus,income,oc‐cupational status, employment, social class and socio‐economicfactors.ThiswasmodifiedasnecessaryforeachdatabaseandcanbefoundinAppendixS1.
Inclusioncriteriaforthereviewwereasfollows:
• Studies involving patient perspectives on actual and desiredquestion asking, raising concerns, involvement in decisionmak‐ing,rapportbuilding,orexpressionofopinions,preferencesandemotions.
• SESgradientmeasuredintheformofeducation,income,occupa‐tionor‘othermeasures’whichincludedpatients’healthinsurancestatus, incomeindicatorsofstatebenefitsandarea‐basedmea‐suresrelatingtothepatients’homeaddress.
• Publishedin1980onwards.• Studiesinvolvingadultpatients.• Onlystudieswhichfocusedondoctor–patientinteractions.• WritteninEnglishlanguageonly.

Thetitleandabstractsof4718articleswereimportedintoEndnote,and368duplicateswereremoved.Thisleft4350entries,ofwhich3989 articles were excluded leaving 361 entries. After screeningall361full‐textarticles,thetworeviewersdisagreedon11papers.Followingdiscussion,sevenpaperswereexcluded.Afterscreening,49studieswereincludedinthereview.ThePRISMAdiagramcanbefoundinFigure1.
Detailsofthecharacteristicsofthe49includedstudiescanbefound inTable1.Overall,39 (79.6%)of the includedstudieswerepublishedinthelast10years,withonly10beingpublishedbefore2008. Most of the studies were conducted in the United States(46.9%), with the Netherlands being the second most common(10.2%).TherewereonlythreestudiesconductedinAustralia,andonly threeconducted in theUK. ‘Other’ countries includedSpain,Estonia,Germany,NorwayandFinland(Figure2).
The majority of studies used questionnaires to collect data(75.5%),withonlyfivestudiesusingqualitativetechniquessuchasinterviewsorfocusgroups,andonlytwostudies13,14wereinterven‐tions.Bothinterventionswerepilotstudieswithnocontrolgroup.The most commonly studied condition was cancer (20.4%), withfourstudiesrecruitingarthritispatients,andfourstudieswithdia‐betespatients.Moststudiesdidnotspecifywhatcondition(ifany)theirparticipantshad (36.7%). ‘Other’conditions includedasthma,chronicpain,HIV,multiplesclerosisandinflammatoryboweldisease(Figure3).NoneofthethreeUKstudiesrecruitedcancerpatients.
Themostcommonsettingforstudiesinvolvedsecondaryorter‐tiary care (44.9%),with primary care being the setting in only 11studies.Unfortunately,16studiesdidnotspecifywhichsettingtheirresearch referred to when collecting data from participants. Themostcommonlystudiedpatientparticipationbehaviourwasinvolve‐mentindecisionmaking(46studies),whereasfivestudiesexaminedraising concerns,14‐18 and only one study looked at rapport build‐ing.19Question asking and expression of opinions, preferences oremotionswasmorecommonlystudied,featuringin13and12stud‐ies, respectively.The rapportbuildingstudy recruitedparticipantsfromthegeneralpopulationandsotherewasalackofstudieswhichfocusedonrapportbuildingwhichinvolvedparticipantsinahealthsetting.Threeoftheraisingconcernsstudieswerewithbreastcan‐cerpatients(Table2).
Themostcommonlyusedmeasuretoexplorerelationshipsbe‐tween patient participation behaviours and SES was educationallevel (45 studies).Only four studiesusedoccupationasan indica‐torofSES,20‐23andonlytwostudiesusedacompositemeasureofdeprivation.24,25Onestudymeasuredhousingsituationandreceiptofbenefits,26oneusedacompositemeasureofsocialclass,27 and onelookedatfinancialstrainandfinancesattheendofthemonth.28
It isalsoimportanttonotethatmanystudiesexaminedmorethanonetypeofpatientparticipationbehaviourorusedmorethanonemeasureofSES.Moststudies(33)usedmorethanonemeasureofSES,whereasonly18studiesexaminedmorethanonetypeofpa‐tientparticipationbehaviour(Table2).
Table1showsthedirectionofassociations reported in the in‐cludedstudies.Ofthe49 includedstudies,5didnotperformsta‐tistical analyses as they had employed qualitativemethodologies.Positive associations between SES and patient participation be‐haviours (PPBs) were reported by 24 studies, while 5 studies re‐ported negative associations. Twenty‐seven studies reported noassociationbetweenatleastsomeoftheirvariables.ElevenstudiesreportedassociationsofdifferingdirectionsfordifferentmeasuresofSESordifferentPPBswithintheirstudy.Sincethestudiesweresomixedintermsofdesign,participants’condition,outcomesandsetting,itwasnotappropriatetoundertakeanymeta‐analyses.

Althoughpreviousstudieshavefoundthatrapportbuilding inthedoctor–patientrelationshipcanhaveanumberofpositiveout‐comes, including treatment satisfaction, understanding health in‐formation,copingandadherencetotreatment,1,3,31onlyonestudywas identifiedwhich lookedathowthisbehaviourwasrelatedtoSESdifference,andsofurtherresearch inthisarea isparticularlyneeded.
Most studies used more than one measure of SES which insome cases allowed a comparison of the effects of each differ‐entmeasure,althoughinsomeofthese,notalltheSESvariableswereentered into theanalysisbutweresimplyusedtodescribethesample.Theobjectiveofourstudywastomaptheliteratureinthisarearatherthantoproduceasynthesisacrossseveraltypesofstudies;however,weextracteddatafromincludedstudiesonwhether a statistically significant association between SES andPPB had been reported. This indicated that although PPB wasfoundtobe related toSES inabouthalfof thestudies, inabouthalf, theywerenot.Summarizingresultsaremademoredifficultby the heterogeneitywhich exists between studies in this area,and the range of different measures of SES and indicators ofPPBwhichhadbeenused.Forexample,althoughseveralstudiesshowed an association with education and patient participationbehaviours,asmanyas17studiesfoundnostatisticallysignificantassociationbetweenthetwovariables;andsotherelationshipislikelytobecomplex.Ontheotherhand,fewstudiesseemtohavefoundasignificantassociationbetweenpatientparticipationbe‐haviours and employment or income. Larger andmore sophisti‐cated studies are needed, using a rangeof SES indicators and amorein‐depthdescriptionofpatientparticipationbehaviours,andthesettinginvolved.
Whilethemostcommonconditionstudiedwascancerandthemost common settingwas secondary or tertiary care, 36.7% ofstudies did not specifywhat condition (if any) their participantswerediagnosedwithorwhathealth‐caresettingtheirquestionsregardingpatientparticipationreferredto.Thisispotentiallyim‐portantinformationwhichismissingfromthesestudies,assettingand condition which the patient is consulting for can influencea patient's preferred and experienced level of participation in aconsultation.7,32,33
Most studies included in the review were conducted in theUnitedStates,makingthecurrentresearchinthisareaveryUS‐cen‐tric.Thismaylimitthegeneralizabilityoftheresultsofthesestudies,asothercountrieshavedifferentlystructuredhealth‐caresystemswhichmight influencepatient participationbehaviours. There is aneed formorestudiesonpatientparticipationbehavioursoutsideoftheUnitedStates.
