    socialdisorganization,endemictoslumareas(ShawandMcKay 1931, 1942;Thrasher[1927]1963).Oneoutgrowthof thislineofreasoningwascontroltheory,suggestingthatentryintodeviantpeergroupsisafunctionofalackofsocialcontrolexperiencedbyyouth(Hirschi1969).Deviantgroups suchasgangsalsohavebeenviewed asthecontextfordifferentialassociationthroughwhichcriminalbehaviorsarelearned(SutherlandandCressey 1978). Othertheoristsdescribeddelinquentsubcultureswithinthelower-andworkingclasscommunities(Cohen 1955;Cohen andShort1958)thattheearlierChicagotheoristsbelievedtobetheorigin ofgangformation. Miller(1958)suggestedthatyouthwhoengageingangdelinquencyarebehavinginamannerconsistentwithlower-classculture.Finally,straintheoristssuggestedthatdelinquencyandganginvolvementarise asanadaptationtostructuralpressures: blockedconventionalopportunitiesleadtofrustration,whichleadstoantisocialactsandthepursuitofgainthroughillegitimateopportunities(ClowardandOhlin 1960). Recentcontributorstogang theoryhave revivedthesocialdisorganizationtradition(BursikandGrasmick 1993;SpergelandCurry1993), oftenembedding itintheunderclass conceptofsocialdisadvantageandeconomicinequality(Fagan 1996;Short1996;Wilson 1987,1996).RISKFACTORS FOR GANG MEMBERSHIPReviewsofthelast30yearsoflongitudinalresearchhaveidentifiedanumberofpredictorsofdelinquencyandviolence(Hawkinsetal.1998; LipseyandDerzon1998;Loeberetal.1991)and substance abuse(Hawkins,Arthur,andCatalano 1995; Hawkins,Catalano,andMiller1992;SimchaFagan, Gersten,andLangner1986).Althoughdelinquency, violence,and substanceabusearenotsynonymouswithgangmembership,predictorsofthesebehaviorsprovideastartingpointforexamining thepredictorsofgangmembership.Thesepredictorsofdelinquency,violence,andsubstance abusearesummarizedinTable 1.Severalofthefactors inTable1havebeenfoundto distinguishgangfromnongangmembers incross-sectionalstudies(seeHowell 1997).Theseincludeneighborhood factorssuchasavailabilityof drugs(CurryandSpergel1992, Hagedorn 1988, 1994a,1994b),familyfactorssuchaspoorfamilymanagementandlowbonding tofamily(Adler,Ovando, and Hocevar1984;Bowkerand Klein1983; Friedman, Mann,andFriedman 1975;Maxson, Whitlock,andKlein1998),schoolfactorssuchaslowcommitmenttoschool(BowkerandKlein1983;Maxsonetal.1998), peerfactorssuchasassociationwithdelinquentpeers(Fagan1990;Maxsonetal.1998;VigilandYun 1990),andindividualfactorssuchasfewerconventionalbeliefs(Fagan1990)andpositiveattitudesaboutgangmembership(Friedmanetal.1975).Moore(1978, 1991)retrospectivelyexaminedfamily historiesofgangmembers,althoughwithoutthebenefitofacomparisongroup.Gang members reportedfrequentconflictandabuse amongtheirparents,childabuse,familymemberalcoholismanddrugaddiction,andfamilytroublewiththepolice.Todate,only twolongitudinalstudieshavereportedprospectivedataongangparticipation:theRochesterYouthDevelopmentStudy(Bjerregaardand Smith1993;Lizotteetal.1994;Thornberry etal.1993)andtheDenverYouthSurvey(EsbensenandHuizinga1993;Esbensen, Huizinga,andWeiher1993). IntheRochesterStudy,Bjerregaardand Smith(1993)examinedfactorsassociatedwithgangmembershipusingwavestwoandthree of theirstudy(coveringages13to15)andfoundsubstantial similarityamong malesandfemalesintherisk factorsassociatedwithgangparticipation.They foundthat,inRochester, neithersocialdisorganizationnorpovertywassignificantlyrelatedtogangmembership. However,they acknowledgedthatbecause thestudyoversampledhigh-riskyouth,therangeof the socialdisorganizationvariables waslimited.Having lowexpectationsforcompletingschoolsignificantlypredictedgangmembershipamongfemalesbutnotamong males. Havingdelinquentpeerswassignificantforbothgroups.Neitherattachment toparentsnorfamilysupervisionwasasignificantpredictoroflatergang membership.Lowself-esteemalsowasunrelatedtogangmembership.Earlysexualactivitywassignificantlyrelatedtogangmembershipforbothsexes,andtheassociationwassignificantlystrongerfor femalesthanformales.Theseanalysesmaybesomewhatconfounded, however, bythefactthatthepredictorsweredrawnfromwave twooftheirstudy,whereasgangmembershipwasameasurethatcombinedwavestwoandthree.Thus,clear statementsastowhetherthesefactorswerepredictorsorconsequencesofgang membershiparedifficulttomakefromtheseanalyses.IntheDenversample, Esbensenetal.(1993)examineddifferencesatwavethree oftheirstudy(malesandfemales,ages11to17)forthose youthwhowereeithergangmembers,nongangstreetoffenders(committed rape,robbery,oraggravatedassault),orneitheratwavefour(ages12to18).Comparedwithnonoffenders, bothgangmembersandnongangstreetoffendersreported(1)higherlevelsof commitmenttodelinquentpeers;(2)lowercommitmenttopositivepeers;(3)higherlevelsofnormlessnessin thefamily,peergroup,andschool context;(4)morenegativelabelingbyteachers;and(5)highertoleranceforcriminalactivityonthepartoftheirpeers.However, nodifferenceswereobservedamongthe threegroupswithrespecttosocialisolation,perceivedlimitedopportunities,andself-conceptmeasures.
