NCT04074681

Brief Summary

The aim of this study is to assess the efficacy of an online CBT-based intervention combined with an Ecological Momentary Intervention (EMI) and different complementary tools for the treatment of problem gambling and gambling disorder. The main hypothesis is that the Internet-based psychological intervention group will obtain better results than the waiting list control group.

Outcome Measures

Primary Outcomes (2)

  • Change in the Gambling Symptom Assessment Scale (G-SAS; Kim, Grant, Potenza, Blanco & Hollander, 2009) at Pre-intervention, Post-module, Post-intervention, 3-, 6-, and 12 months Follow-up.

    The G-SAS is a 12-item self-report instrument that assesses gambling symptom severity. All items are referred to as an average symptom based on the past 7 days.The statements correspond with gambling urges;average frequency, duration,and control of thoughts associated with gambling;time spent on gambling or gambling-related behaviour;anticipatory excitement caused by an imminent gambling act; pleasure associated with winning;emotional distress;and personal trouble.All items are rated on a 4-point scale (total score: 0-48).The higher score the higher gambling symptoms severity (mild=8-20;moderate=21-30;severe=31-40;extreme=41-48).It shows high internal consistency (α=0.87) and good convergent validity with other measures associated with gambling symptom severity in a sample of pathological gamblers.Because this instrument has not a Spanish version, standardized procedures were followed to adapt G-SAS to the Spanish language.Cronbach's alpha will be calculated with the data at hand.

    Up to 12 months

  • Change in the Gambling-Related Cognitions Scale (GRCS-S; Raylu & Oei, 2004; Spanish validation Del Prete, Steward, Navas, Fernández-Aranda, Jiménez-Murcia, Oei & Perales, 2016) at Pre-intervention, Post-intervention, 3-, 6-, and 12 months Follow-up.

    The GRCS-S is a self-report instrument aimed to assess five domains of gambling-related cognitions (interpretative bias, IB; the illusion of control, IC; predictive control, PC; gambling expectancies, GE; and perceived inability to stop gambling, ISG). It comprises 23 items which are worded on a 7-point Likert type scale (1= I completely disagree; 7=I completely agree). The total score consists of adding the values of the whole items. The score for each subscale is obtained adding the values for the items' set that represent each subscale. The higher the total score the higher the number of gambling-related cognitions presented. GRCS-S shows adequate psychometric properties in a sample composed by treatment-seeking gamblers and non-treatment-seeking gamblers: the concurrent and criterion-related validity are verified, the full scale reliability is 0.95, and for each subscale reliability ranges from 0.68 to 0.91 (GE= 0.77; IC=0.68; PC=0.84; ISG=0.91; IB= 0.89).

    Up to 12 months

Secondary Outcomes (3)

  • Change in the Gambling Self-Efficacy Questionnaire (GSEQ; May, Whelan, Steenbergh & Meyers, 2003; Winfree, Ginley, Whelan, & Meyers, 2014) at Pre-intervention, Post-module, Post-intervention, 3-, 6-, and 12 months Follow-up.

    Up to 12 months

  • Change in the University of Rhode Island Change Assessment Scale (URICA; McConnaughy, Prochaska & Velicer, 1983; Spanish validation Gómez-Peña et al., 2011) at Pre-intervention, Post-intervention, 3-, 6-, and 12 months Follow-up.

    Up to 12 months

  • Change in the EMI measures during procedure.

    During procedure.

Other Outcomes (11)

  • Change in the NORC DSM-IV Screen for Gambling Problems (NODS; Gernstein et al., 1999; Becoña, 2004) at Pre-intervention (screening), Post-intervention, 3-, 6- and 12 months Follow-up.

    Up to 12 months

  • Mini International Neuropsychiatric Interview - The M.I.N.I. 7.0.2, 8/8/16 version (Sheehan, 2016).

    Pre-intervention (screening)

  • Gambling history interview and current gambling situation and related variables assessment at the pre-intervention (screening)

    Pre-intervention (screening)

  • +8 more other outcomes

Study Arms (2)

Gambling Internet-based Protocol

EXPERIMENTAL

Intervention group that carries out the Gambling Internet-based Protocol based on Cognitive and Behavioral Therapy (CBT) and receives support by the therapist (a weekly 10-minute phone call without clinical content). In addition, they will receive one notification per day to respond to the EMI questions at 8 PM. The EMI includes immediate automatic feedback depending on the participant's responses.

Behavioral: Gambling Internet-based Protocol

Waiting List Control Group

NO INTERVENTION

Participants in a 12-week waiting list control condition. They will be offered the possibility of receiving the online treatment protocol after the waiting list period.

Interventions

Gambling Internet-based protocol is a multimedia interactive and self-help program for problem and pathological gamblers, which will allow individuals to learn and practice adaptive ways to cope with this problem. The main therapeutic modules included in this program are: 1) Motivational for change; 2) Psychoeducation; 3) Stimulus control (e.g. self-prohibition and blocking of usual gambling websites with therapist confirmation) and responsible return of debts; 4) Cognitive restructuring; 5) Emotion regulation; 6) Planning of significant activities; 7) Coping skills and exposure with response prevention; 8) Relapse prevention.
