Subtypes of British Adolescents Involved in Adolescent Dating Violence

Kate Walker & Erica Bowen

Background: Adolescent Dating Violence

Adolescent dating violence: The problems and prevalence

• Verbal, psychological and physical aggression are common features of adolescent dating relationships (e.g., Banyard & Cross, 2008; Danielsson, Blom, Nilses, Heimer, & Högberg, 2009; Reed, Silverman, Raj, Decker, & Miller, 2011)• 35% report mild form of abuse • 10-20% report more severe forms (Black et al., 2011)

• Comprehensive international review (Europe and North America; Leen et al., 2013) found rates of physical ADV ranged between 10 and 20% and psychological 17 and 88% in general population samples

• Perpetration and victimisation co-occur (e.g., Foshee et al., 1996; Gray & Foshee, 1997; Malik, Sorenson, & Aneshensel, 1997) i.e., a perpetrator is likely to be a victim, and a victim is likely to be a perpetrator

Typologies• Johnson (1995, 2008) Typology research in adults:

– Intimate Terrorism (IT), Violent Resistant (VR), Situational Couple Violence (SCV), Mutual Violent Control (MVC)

– Applied recently to ADV (Zweig et al. 2014): SCV most common (86% females; 80% males); IT (7% females; 11% males); VR (6% females; 6% males); MVC (1% females; 4% males)

• Only few other studies examined typologies of ADV (Bossarte, Simon, & Swahn, 2008; Draucker et al., 2010; Draucker et al., 2012; Foshee, Bauman, Linder, Rice, & Wilcher, 2007; Haynie et al., 2013)– Mutuality was a dominant characteristic of violence, but the motives for such a

presentation varied between types– Need to understand the role that each of the individual plays in relation to the

use, severity and types of violence employed– Little is known about role of control in ADV

Current Research

To extend typology research in adults to explore mutuality in use of violence in adolescent dating relationships

Aims Twofold:(1) To determine the prevalence of physical and psychological violence and controlling behaviours in a UK sample of adolescents in the context of a dating relationship(2) To determine whether meaningful subtypes of adolescents are evident based on involvement in physical ADV and if subtypes differ in relation to psychological violence and controlling behaviours

Research593 adolescents 203 males (34.2%), 390 females (65.8%)

Mean age 14.33 years (SD = 0.90, range 12.00 to 16.42 years) Mean age for

first relationship 11.25 years (SD = 2.32) Mean number of dating relationships 3.24 (SD = 3.10)

Clusters developedCluster analysis used on frequency scores of the PDR & VDR• Cluster 1: Low frequency victim/perpetrator group, (n = 152). Low

levels of victimisation and perpetration, but frequency of victimisation (M = 2.00, SE = .16) was higher than frequency of perpetration (M = .60, SE = .10) and the difference was significant t (151) = -9.53 p < .001, d = 0.61.

• Cluster 2: Moderate frequency victim/perpetrator group, (n = 40). Moderate levels of victimisation and perpetration, but frequency of victimisation (M = 9.50, SE = .86) was higher than frequency of perpetration (M = 5.01, SE = .47) and the difference was significant t (39) = -4.06 p < .001, d = 0.61.

• Cluster 3: High frequency perpetration/victimisation group, (n = 19). High levels of victimisation and perpetration, but frequency of perpetration (M = 23.49, SE = 1.82) was higher than frequency of victimisation (M = 20.44, SE = 1.64) and the difference was significant t (18) = 2.84 p < .05, d = 0.56.

Subtypes• Examination of the frequency of roles within each behavioural

subgroup (victim, perpetrator, mutual)• 5 subgroups developed

Cluster 1 Cluster 2 Cluster 3

Low frequency perpetrator (LP)(n = 18, 11.8%)

Moderate frequency mutual (MM) (n = 36, 90%)

High frequency mutual (HM) (n = 19, 100%).

Low frequency victim(LV)(n = 64, 42.1%) Low frequency mutual (LM)(n = 70, 46.1%)

Validation of SubtypesValidation of group memberships using psychological abuse and

controlling behaviours

Significant effects of group on: • Scores of controlling behaviour perpetration F (5, 583) = 107.95, p

< .001, partial η2 = .48• Scores of controlling behaviour victimisation F (5, 583) = 88.10, p

< .001, partial η2 = .43• Perpetration of psychological violence F (5, 583) = 97.60, p < .001,

partial η2 = .46• Victimisation of psychological violence F (5, 583) = 113.59, p < .001,

partial η2 = .49)

Conclusions

Adolescents who report ADV involvement were heterogeneous in relation to the nature of their involvement

CLUSTERS:5 subtypes

Perpetration and victimisation co-occurOf 5 subtypes 60% participants reported co-

occurrenceUse of control and psychological abuse (P &

V) distinguished groups

Implications

• Findings have potential to advance theory on the heterogeneity of violence in ADV

• Based on prevalence intervention and prevention required within the school curriculum– Typology research; examine behaviours of both

partners and different behaviours (physical, psychological, controlling)
