Online Intervention to Promote Change and Help-Seeking in Young Adults With Gambling and Trading Problems

January 28, 2026 updated by: Ainhoa Coloma Carmona, Universidad Miguel Hernandez de Elche

Online Personalized Normative Feedback to Foster Intention to Change and Help-Seeking in Young Adults With Gambling- and Trading-Related Problems: An Experimental Study

The goal of this study is to investigate if personalized online normative feedback (PONF) can increase intention to change and help-seeking behaviors in young adults with gambling or trading problems in Spain. The main questions it aims to answer are:

  1. Does PONF increase intention to change and help-seeking behaviors?
  2. How does receiving PONF affect gambling and trading behaviors?

Researchers will compare three groups:

  • Evaluation group: A control group with pre- and post-assessments.
  • Delayed evaluation group: A control group with only a post-assessment, to control for the effect of the assessment.
  • FNPO group: An intervention group receiving PONF after the initial evaluation and completing both pre- and post-assessments.

Participants will:

  • Receive PONF or no feedback at the first evaluation.
  • Complete initial and follow-up assessments after 12 weeks.

Detailed Description

Despite the availability of treatment options, the percentage of individuals with problem gambling who seek help or treatment remains low. To reach a larger number of pathological gamblers, other forms of online or self-guided interventions have been developed, with personalised normative feedback (NPF) being the most widely applied modality in the prevention of problem gambling in the young adult population. However, the majority of studies on the efficacy of PNF only assess its impact on the intensity and severity of gambling behaviour, and do not analyse its potential effect on increasing intention to change and treatment-seeking behaviour. Furthermore, there is a lack of studies analyzing the efficacy of NPF in reducing new forms of online money spending linked to pathological gambling, such as betting on video games and excessive trading of financial assets, including cryptocurrencies.

The present project has two objectives: (1) to quantify the intention to change and the prevalence of help-seeking behaviours in the Spanish young adult population with pathological gambling or trading behaviours; and (2) to analyze the effectiveness of personalised online normative feedback (PONF) to increase intention to change and help-seeking in this population.

The study will employ a randomised controlled design (three Solomon groups) with one intervention group and two control groups. The study will involve a sample of at least 656 men and women living in Spain, aged between 18 and 34 years. The impact of receiving FNPO on gambling and trading behaviour will be analysed over a 12-week period. This will include an assessment of the intention to change and treatment seeking, as well as the longitudinal trajectory of gambling and trading behaviours (in terms of intensity, frequency and severity). Furthermore, individual, interpersonal and contextual factors will be evaluated in order to ascertain the profile of those with gambling and trading issues who may derive the greatest benefit from this type of intervention.

This project is pioneering both nationally and internationally. Furthermore, this study will assess for the first time the intention to change and help-seeking in young adults with gambling behaviour (in traditional and new formats such as video games) and pathological trading. It will also develop and analyze the effectiveness of the first tool to mobilize change and reduce the prevalence of these behaviours. Furthermore, the study design will enable an independent assessment of the impact of both the intervention and the assessment of pathological gambling and trading behaviours on the individual.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Control group 1 (Assessment group)
Participants in this group will complete both pre- and post-assessments on intention to change, help-seeking behavior, and gambling/trading behaviors. However, they will not receive any feedback. This group serves as a comparison to both intervention groups.
No Intervention: Control group 2 (Delayed Assessment Group)
This group will complete only the post-assessment, measuring intention to change, help-seeking behavior, and gambling/trading behaviors, without completing a pre-test or receiving feedback, to independently analyze the immediate effects of the pre-test.
Experimental: Personalized Online Normative Feedback (PONF)

Participants in this group complete a pre-assessment measuring intention to change, help-seeking behavior, and gambling and trading behaviors (e.g., frequency and spending). They then receive personalized online normative feedback (PONF) based on their initial assessment and subsequently complete a post-assessment including the same outcomes.

Within this intervention arm, participants are randomly assigned to one of two predefined assessment sequences (PNF-A vs. PNF-B), differing only in the timing of the post-intervention assessment of gambling and trading behaviors. This sequencing is implemented exclusively to support secondary analyses of potential reporting reactivity (e.g., social desirability) and does not involve any differences in intervention content, delivery, or assessment of the primary motivational outcomes.

Those participating in this condition will receive a personalised brief report which summarises the results of their initial assessment. The PONF will comprise the following elements: (1) Details of the main gambling and trading activities performed, including frequency of engagement and amount of money spent; (2) Scores on the criteria of pathological trading and/or PGSI (problem gambling), together with an interpretation of the results and the level of severity. All results will be accompanied by graphs enabling participants to compare their scores with the average scores of the Spanish population of the same sex and age range. To prevent an increase in behaviour in participants whose frequency or intensity of gambling/trading is below the norm, as recommended by Newall et al. (2023), the normative data will include extreme averages and percentages. All participants assigned to the PNF intervention receive identical feedback content, regardless of assessment sequencing.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Intention to change
Time Frame: Baseline, immediate follow-up (after PONF), 3-month follow-up
The study will assess intention to change and help-seeking behavior using three custom items. In the initial assessment, participants will respond to a dichotomous question regarding whether they have considered reducing or abandoning gambling/trading in the past year. They will also rate the likelihood of engaging in these behaviors over the next 12 months on a scale from 0% (not likely) to 100% (very likely). Finally, participants will indicate their goal regarding their gambling/trading behavior, choosing from options to reduce, increase, maintain, or cease the behavior.
Baseline, immediate follow-up (after PONF), 3-month follow-up
Treatment-seeking behavior
Time Frame: Baseline, immediate follow-up (after PONF), 3-month follow-up
Treatment-seeking behavior will be assessed during the initial evaluation using a the following question: "Have you ever sought professional help, advice from family or friends, or done something on your own to limit or reduce your [gambling/trading] behavior?" If participants answer "yes," they will complete the Help-Seeking Questionnaire (HSQ), which includes 14 items assessing in-person (e.g., seeing a psychologist), remote (e.g., calling a helpline), and self-directed (e.g., reading forums or searching websites) help-seeking behaviors.
Baseline, immediate follow-up (after PONF), 3-month follow-up

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Gambling and trading behaviors
Time Frame: Baseline, immediate follow-up (after PONF), 3-month follow-up
The frequency and intensity of gambling and trading behaviors will be assessed with ad-hoc items. Gambling behavior will be evaluated with reference to the last year during the initial and post-test assessments, and for the last month during the 3-month follow-up. Trading behavior will focus on financial operations, types of trading, and frequency of market monitoring. A dichotomous item will also assess whether participants engage in professional or amateur trading.
Baseline, immediate follow-up (after PONF), 3-month follow-up
Disordered gambling
Time Frame: Baseline, 3-month follow-up

The Problem Gambling Severity Index (PGSI) and the Gambling Disorder Identification Test (GDIT) will be used to assess problem gambling. The Problem Gambling Severity Index (9 items) categorises participants as non-problem, low-risk, moderate-risk, or problem gambling. The total score ranges from 0 to 27, with higher scores indicating a greater severity of gambling problems.

The investigators will adapt the Gambling Disorder Identification Test, a 14-item Likert scale, to Spanish and validate it as a new measure. It evaluates gambling behaviours, symptoms, and negative consequences, categorising participants as non-gamblers, recreational gamblers, or problematic gamblers (mild, moderate, severe). The total score of the scale ranges from 0 to 62, with higher scores indicating more severe gambling disorder.

Baseline, 3-month follow-up
Disordered trading
Time Frame: Baseline, 3-month follow-up
Trading Disorder Scale which is based on the diagnostic criteria for gambling disorder from the DSM-5, adapted to evaluate problematic trading behaviors. This scale evaluates various dimensions of addictive behavior, including tolerance, withdrawal, loss of control, craving, social impairment, and continued engagement despite negative consequences. The total score of the scale ranges from 0 to 13, with scores ≥5 indicates the possible presence of disordered trading.
Baseline, 3-month follow-up

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Gambling and trading-related harms
Time Frame: Baseline and 3-month follow-up
An adapted version of the Short Gambling Harm Screen will be used to evaluate harms related to both gambling and trading activities, employing a yes/no response format. Scores range from 0 to 10, with higher scores indicating greater gambling/trading-related harm.
Baseline and 3-month follow-up
Gambling and trading self-efficacy
Time Frame: Baseline and 3-month follow-up
The Brief Situational Questionnaire, adapted for gambling and trading behaviors, will assess self-efficacy in resisting gambling or trading across 10 specific scenarios. Scores range from 0 to 100, reflecting the degree of self-efficacy to resist these behaviors, with higher scores indicating stronger self-efficacy in handling such situations.
Baseline and 3-month follow-up
Peer gambling and trading
Time Frame: Baseline
It will be assessed using a custom dichotomous item (yes/no) that evaluates whether the participant's friends or family engage in gambling, trading or financial investments.
Baseline
Satisfaction and perceived usefulness
Time Frame: Immediate follow-up
Feedback on the satisfaction with the personalized normative feedback received and the perceived usefulness of the information provided will be assessed using a 4-point Likert questionnaire (only in intervention groups). Scores range from 1 to 4, with higher scores reflect greater satisfaction and perceived usefulness of the PONF.
Immediate follow-up
