Participants and Methods: Data was collected via mTurk. Adults (N = 106) who endorsed regularly gaming and who were determined to meet provisional criteria for PTSD completed the PTSD Checklist for DSM-5 (PCL-5) with Life Events Checklist for DSM-5 (LEC-5), Post-Traumatic Maladaptive Beliefs Scale (PMBS; Vogt et al., 2010), UPPS-P Impulsive Behavior Scale (Lynam et al., 2006), and the Internet Gaming Disorder Scale-Short Form (IGDS9-SF). Results: There was a significant, positive relationship between total scores on the PCL-5 and PMBS (r = .24, p < 0.05), and between total scores on the UPPS-P and IGDS9-SF, r = .33, p < .01. The relationship between PTSD symptom severity and general impulsivity was not significant. There was a significant, positive relationship between scores on the PCL-5 and IGDS9-SF, r = .37, p < .001, between negative urgency scores and maladaptive changes in cognition, r =.27, p = .01, and between negative urgency scores and problematic gaming behavior scores, r = .26, p < .05. Hierarchical regression analyses revealed that PCL-5 scores explained 13.7% of variance in IGDS9-SF scores, which was significant, R² = .137, F(1, 72) = 11.44, p = .001. PMBS scores did not significantly account for additional variance in IGDS9-SF scores over and above PCL-5 scores. Hierarchical regression analyses revealed that impulsivity assessed by the facets of lack of premeditation, lack of perseverance, sensation seeking, and positive urgency explained 16.8% of variance in IGDS9-SF scores, which was significant, R² = .168, F(4, 69) = 3.49, p = .012. Symptom severity of PTSD assessed by PCL-5 scores added 10.6% of variance in IGDS9-SF scores over above the previously described facets of impulsivity, which was significant, ΔR²= .106, ΔF(1, 68) = 9.93, p = .002. Negative urgency did not significantly account for additional variance over and above the other facets of impulsivity and PCL-5 scores. A third hierarchical regression analysis revealed that negative urgency and PMBS scores entered jointly did not significantly account for additional variance in IGDS9-SF scores over and above PCL-5 scores. The relationship between PTSD symptom severity and problematic gaming behaviors was not mediated by negative urgency, nor by maladaptive changes in cognition. Conclusions: Greater PTSD symptom severity and higher rates of impulsivity were both positively associated with rates of problematic gaming behaviors. PTSD symptom severity and impulsivity were not significantly associated with each other; however, negative urgency was positively associated with maladaptive changes in cognition and with problematic gaming behaviors. Neither negative urgency nor maladaptive changes in cognition associated with trauma mediated the relationship between PTSD symptom severity and problematic gaming behaviors. More work is needed to clarify the nature of these relationships to inform treatment, but it appears that much of what is understood about PTSD, impulsivity, and addiction in adults, can be extended to problematic gaming behaviors.

Objective:

The current study investigated the complex relationships between impulsivity, maladaptive changes in cognition associated with trauma, and their relationship with problematic gaming behaviors.

Participants and Methods:

Data was collected via mTurk. Adults (N = 106) who endorsed regularly gaming and who were determined to meet provisional criteria for PTSD completed the PTSD Checklist for DSM-5 (PCL-5) with Life Events Checklist for DSM-5 (LEC-5), Post-Traumatic Maladaptive Beliefs Scale (PMBS; Vogt et al., 2010), UPPS-P Impulsive Behavior Scale (Lynam et al., 2006), and the Internet Gaming Disorder Scale-Short Form (IGDS9-SF).

Results:

There was a significant, positive relationship between total scores on the PCL-5 and PMBS (r = .24, p < 0.05), and between total scores on the UPPS-P and IGDS9-SF, r = .33, p < .01. The relationship between PTSD symptom severity and general impulsivity was not significant. There was a significant, positive relationship between scores on the PCL-5 and IGDS9-SF, r = .37, p < .001, between negative urgency scores and maladaptive changes in cognition, r =.27, p = .01, and between negative urgency scores and problematic gaming behavior scores, r = .26, p < .05. Hierarchical regression analyses revealed that PCL-5 scores explained 13.7% of variance in IGDS9-SF scores, which was significant, R² = .137, F(1, 72) = 11.44, p = .001. PMBS scores did not significantly account for additional variance in IGDS9-SF scores over and above PCL-5 scores. Hierarchical regression analyses revealed that impulsivity assessed by the facets of lack of premeditation, lack of perseverance, sensation seeking, and positive urgency explained 16.8% of variance in IGDS9-SF scores, which was significant, R² = .168, F(4, 69) = 3.49, p = .012. Symptom severity of PTSD assessed by PCL-5 scores added 10.6% of variance in IGDS9-SF scores over above the previously described facets of impulsivity, which was significant, ΔR²= .106, ΔF(1, 68) = 9.93, p = .002. Negative urgency did not significantly account for additional variance over and above the other facets of impulsivity and PCL-5 scores. A third hierarchical regression analysis revealed that negative urgency and PMBS scores entered jointly did not significantly account for additional variance in IGDS9-SF scores over and above PCL-5 scores. The relationship between PTSD symptom severity and problematic gaming behaviors was not mediated by negative urgency, nor by maladaptive changes in cognition.

Conclusions:

Greater PTSD symptom severity and higher rates of impulsivity were both positively associated with rates of problematic gaming behaviors. PTSD symptom severity and impulsivity were not significantly associated with each other; however, negative urgency was positively associated with maladaptive changes in cognition and with problematic gaming behaviors. Neither negative urgency nor maladaptive changes in cognition associated with trauma mediated the relationship between PTSD symptom severity and problematic gaming behaviors. More work is needed to clarify the nature of these relationships to inform treatment, but it appears that much of what is understood about PTSD, impulsivity, and addiction in adults, can be extended to problematic gaming behaviors.
