Response trajectories of gambling severity after cognitive behavioral therapy in young-adult pathological gamblers

Background and aims: The significant increase in the prevalence of gambling disorder (GD) among young adults in recent years has attracted interest in determining therapeutic efficiency in this sector of the population. The aim of this work was to estimate the response trajectories of gambling severity during the six-month follow-up after a cognitive behavioral therapy (CBT) program in young adult patients and to identify the main variables associated with each trajectory. Methods: The sample included n 5 192 patients, aged 19-35 years old, seeking treatment for GD. Response trajectories were identified through latent class growth analysis. Results: Three trajectories emerged: T1 (n 5 118, 61.5%), composed of patients with severe GD at pre-treatment and good evolution to recovery; T2 (n 5 62, 32.3%), with patients with moderate-high GD affectation at baseline and good evolution to recovery; and T3 (n 5 12, 6.3%), with participants with severe baseline GD severity and poor evolution after CBT (Abbott, 2019). The highest risk of poor therapeutic outcomes was related to lower social index positions, high emotional distress, high scores in harm avoidance and low scores in self-directedness. Discussion and conclusions: Differences in the response trajectories at short-term follow-up after CBT reveal heterogeneity in the samples including young and young-adult GD patients. Patients' phenotype at baseline should be considered when developing efficient, person-centered intervention programs, which should comprise strategies aimed at increasing emotional regulation capacities, self-esteem and self-efficacy, with the aim of avoiding relapses in the medium-long term after therapy.
