Abstract

Aims, design and setting: The aim of this study was to test the efficacy of the integrated cognitive-behavioral therapy with a strength-based motivational approach [integrated cognitive-behavioral therapy (ICBT)] intervention to change gaming disorder (GD) symptoms and other outcomes and to study the therapeutic mechanism. A two-arm parallel randomized waiting-list controlled trial with 3- and 6-month follow-ups were conducted in a secondary vocational school in mainland China.

Participants: Participants comprised 77 Chinese adolescents with GD symptoms with a mean age of 16.36 years [standard deviation (SD) = 0.93]; 88.3% were male INTERVENTIONS: Participants were randomized into an ICBT group (n = 38) and a waiting-list control (WLC, n = 39) group. ICBT intervention comprised eight weekly sessions to encourage participants to identify their interests and strengths and set goals for developing personally meaningful real-life activities.

Measurements and findings: The outcomes were measured at pre-treatment (t₀ ), post-treatment (t₁ ), 3-month (t₂ ) and 6-month (t₃ ) follow-ups. The primary outcome was GD symptoms at t3. Secondary outcomes included GD symptoms at t₁ and t₂ , and gaming motivation, maladaptive gaming cognition, depression and anxiety symptoms at t₁ , t₂ and t₃ . With the intention-to-treat principle, the GD scores at t₃ were significantly different between the CBT and WLC groups [mean difference 62.08 (SD = 10.48) versus 73.64 (SD = 11.70); Hedges' g = 1.15, 95% confidence interval = 0.67-1.62]. Linear mixed-effects modeling showed significant group × time interaction for the secondary outcomes (P < 0.01), with a moderate to strong between-group effect size in the reduction in depression symptoms (g = 0.67-0.84) and anxiety symptoms (g = 0.6-0.64). Path analysis shows ICBT leads to GD reduction through reducing gaming motivation and maladaptive gaming cognition.

Conclusions: An integrated cognitive-behavioral therapy with strength-based motivational approach intervention reduced gaming disorder symptoms and time spent gaming over a 6-month period by decreasing maladaptive gaming motivation and cognition.
