Internet Gaming Disorder (IGD) embodies a persistent and recurrent engagement with video games, to the exclusion of other activities, that cannot be controlled, and with significant impairments in everyday functioning. Previous research suggests that IGD is experienced differently depending on the gamer's profile, while distress symptoms such as depression, anxiety, and stress have been independently associated to the development of IGD. Interestingly, no study to date has aimed to profile gamers based on these three psychopathologies. The present study aimed to (a) profile gamers concerning their depression, anxiety, and stress, and (b) examine the differences in IGD levels between the different profiles of distress. A sample consisting of 968 gamers (18-64 years, M age = 29.54) was assessed with the Depression, Anxiety and Stress Scale (DASS-21) and the Internet Gaming Disorder Scale-Short-Form (IGDS9-SF). Latent class analysis (LCA) identified three distinct distress profiles. These encompassed "High-Distress Comorbidity" (HDC; 25.9%), "Medium-Distress Comorbidity" (MDC; 48.7%) and "Low-Distress Comorbidity" (LDC; 25.4%) gamers. As hypothesised, higher distress comorbidity profiles are linked with higher IGD levels. Findings suggest that there are different distress profiles varying by symptom severity, with more distressed gamers presenting with higher IGD levels independent of the specific distress symptom they reported. Thus, differential diagnosis of depression, anxiety, and stress symptoms may not be necessary in the context of IGD treatment, but rather distress behaviours should be targeted concurrently and independent of their nature. Public Significance StatementBoth the type of gamer a person is and their level of distress play a part in the likelihood of developing Internet Gaming Disorder (IGD). Different profiles of distress were examined in relation to IGD levels, with results showing that higher distress profiles were accompanied by higher IGD levels.
Background As nightmares may be a risk factor for, or symptom of, multiple psychological disorders, some researchers suggest that nightmares should be screened, diagnosed, and treated. Treatments for nightmares include trauma-focused Cognitive Behavioural Therapy and Image Rehearsal Therapy, and pharmacological interventions such as prazosin and nitrazepam. As recent research has put into question our current understanding of treatment efficacy, there is a need to systematically review findings related to the effectiveness of nightmare treatments to inform best practice. The current review assessed the efficacy of psychosocial treatments of nightmare in all cohorts. Methods A systematic search of four databases for peer reviewed journal articles from 2000 onwards produced 69 (35 RCTs, 34 non-RCTs) eligible articles that underwent narrative synthesis. Results The results provide strong evidence for exposure and image rehearsal treatments for the reduction of nightmare frequency, severity, and distress, in civilian, military, idiopathic, and posttraumatic stress disorder (PTSD) cohorts. There is emerging evidence that self-guided and brief treatment modalities offer efficient and effective treatment options. There is an urgent need for clinical trials of treatment effectiveness in children. Conclusions The results suggest that treatments for nightmares are most effective when they facilitate a sense of control or mastery by directly targeting the nightmare content and/or the client’s emotional responses to the nightmare content. Trial registration A review protocol was registered with PROSPERO (CRD42020204861).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
